 ### Kinds
 
-Kinds specify how clients should interpret the meaning of each event and the other fields of each event (e.g. an `"r"` tag may have a meaning in an event of kind 1 and an entirely different meaning in an event of kind 10002). Each NIP may define the meaning of a set of kinds that weren't defined elsewhere. This NIP defines two basic kinds:
+Kinds specify how clients should interpret the meaning of each event and the other fields of each event (e.g. an `"r"` tag may have a meaning in an event of kind 1 and an entirely different meaning in an event of kind 10002). Each NIP may define the meaning of a set of kinds that weren't defined elsewhere. [NIP-10](10.md), for instance, specifies the `kind:1` text note for social media applications.
 
-- `0`: **metadata**: the `content` is set to a stringified JSON object `{name: <username>, about: <string>, picture: <url, string>}` describing the user who created the event. A relay may delete older events once it gets a new one for the same pubkey.
-- `1`: **text note**: the `content` is set to the **plaintext** content of a note (anything the user wants to say). Content that must be parsed, such as Markdown and HTML, should not be used. Clients should also not parse content as those.
+This NIP defines one basic kind:
+
+- `0`: **user metadata**: the `content` is set to a stringified JSON object `{name: <nickname or full name>, about: <short bio>, picture: <url of the image>}` describing the user who created the event. [Extra metadata fields](24.md#kind-0) may be set. A relay may delete older events once it gets a new one for the same pubkey.
 
 And also a convention for kind ranges that allow for easier experimentation and flexibility of relay implementation:
 
-- for kind `n` such that `1000 <= n < 10000`, events are **regular**, which means they're all expected to be stored by relays.
+- for kind `n` such that `1000 <= n < 10000 || 4 <= n < 45 || n == 1 || n == 2`, events are **regular**, which means they're all expected to be stored by relays.
 - for kind `n` such that `10000 <= n < 20000 || n == 0 || n == 3`, events are **replaceable**, which means that, for each combination of `pubkey` and `kind`, only the latest event MUST be stored by relays, older versions MAY be discarded.
 - for kind `n` such that `20000 <= n < 30000`, events are **ephemeral**, which means they are not expected to be stored by relays.
-- for kind `n` such that `30000 <= n < 40000`, events are **parameterized replaceable**, which means that, for each combination of `pubkey`, `kind` and the `d` tag's first value, only the latest event MUST be stored by relays, older versions MAY be discarded.

 In case of replaceable events with the same timestamp, the event with the lowest id (first in lexical order) should be retained, and the other discarded.

 ### From client to relay: sending events and creating subscriptions
 
 Clients can send 3 types of messages, which must be JSON arrays, according to the following patterns:

   * `["CLOSE", <subscription_id>]`, used to stop previous subscriptions.
 
-`<subscription_id>` is an arbitrary, non-empty string of max length 64 chars, that should be used to represent a subscription. Relays should manage `<subscription_id>`s independently for each WebSocket connection; even if `<subscription_id>`s are the same string, they should be treated as different subscriptions for different connections.

 ```
 
-Upon receiving a `REQ` message, the relay SHOULD query its internal database and return events that match the filter, then store that filter and send again all future events it receives to that same websocket until the websocket is closed. The `CLOSE` event is received with the same `<subscription_id>` or a new `REQ` is sent using the same `<subscription_id>`, in which case relay MUST overwrite the previous subscription.

 Filter attributes containing lists (`ids`, `authors`, `kinds` and tag filters like `#e`) are JSON arrays with one or more values. At least one of the arrays' values must match the relevant field in an event for the condition to be considered a match. For scalar event attributes such as `authors` and `kind`, the attribute from the event must be contained in the filter list. In the case of tag attributes such as `#e`, for which an event may have multiple values, the event and filter condition values must have at least one item in common.

 A `REQ` message may contain multiple filters. In this case, events that match any of the filters are to be returned, i.e., multiple filters are to be interpreted as `||` conditions.
 
-The `limit` property of a filter is only valid for the initial query and MUST be ignored afterwards. When `limit: n` is present it is assumed that the events returned in the initial query will be the last `n` events ordered by the `created_at`. It is safe to return less events than `limit` specifies, but it is expected that relays do not return (much) more events than requested so clients don't get unnecessarily overwhelmed by data.

If, for any reason, the address `https://bob.com/.well-known/nostr.json?name=bob` starts returning the public key `1d2...e3f` at any time in the future, the client must not replace `abc...def` in his list of followed profiles for the user (but it should stop displaying "bob@bob.com" for that user, as that will have become an invalid `"nip05"` property).

 Clients may treat the identifier `_@domain` as the "root" identifier, and choose to display it as just the `<domain>`. For example, if Bob owns `bob.com`, he may not want an identifier like `bob@bob.com` as that is redundant. Instead, Bob can use the identifier `_@bob.com` and expect Nostr clients to show and treat that as just `bob.com` for all purposes.

-On "e" and "p" tags in Text Events (kind 1).
---------------------------------------------
+Text Notes and Threads
+----------------------
 
 `draft` `optional`
 
+This NIP defines `kind:1` as a simple plaintext note.
+
 ## Abstract
-This NIP describes how to use "e" and "p" tags in text events, especially those that are replies to other text events.  It helps clients thread the replies into a tree rooted at the original event.
 
-## Positional "e" tags (DEPRECATED)
->This scheme is in common use; but should be considered deprecated.
+The `.content` property contains some human-readable text. 
 
-`["e", <event-id>, <relay-url>]`  as per NIP-01.
+`e` tags can be used to define note thread roots and replies. They SHOULD be sorted by the reply stack from root to the direct parent.
+
+`q` tags MAY be used when citing events in the `.content` with [NIP-21](21.md).
+
+```json
+["q", "<event-id> or <event-address>", "<relay-url>", "<pubkey-if-a-regular-event>"]
+```
+
+Authors of the `e` and `q` tags SHOULD be added as `p` tags to notify of a new reply or quote.
+
+Markup languages such as markdown and HTML SHOULD NOT be used. 
+
+## Marked "e" tags (PREFERRED)
+
+Kind 1 events with `e` tags are replies to other kind 1 events. Kind 1 replies MUST NOT be used to reply to other kinds, use [NIP-22](22.md) instead. 
+
+`["e", <event-id>, <relay-url>, <marker>, <pubkey>]`
+
+Where:
+
+ * `<event-id>` is the id of the event being referenced.
+ * `<relay-url>` is the URL of a recommended relay associated with the reference. Clients SHOULD add a valid `<relay-url>` field, but may instead leave it as `""`.
+ * `<marker>` is optional and if present is one of `"reply"`, `"root"`.
+ * `<pubkey>` is optional, SHOULD be the pubkey of the author of the referenced event
+
+Those marked with `"reply"` denote the id of the reply event being responded to.  Those marked with `"root"` denote the root id of the reply thread being responded to. For top level replies (those replying directly to the root event), only the `"root"` marker should be used. 
+
+A direct reply to the root of a thread should have a single marked "e" tag of type "root".
+
+>This scheme is preferred because it allows events to mention others without confusing them with `<reply-id>` or `<root-id>`.
+
+`<pubkey>` SHOULD be the pubkey of the author of the `e` tagged event, this is used in the outbox model to search for that event from the authors write relays where relay hints did not resolve the event.
+
+## The "p" tag
+Used in a text event contains a list of pubkeys used to record who is involved in a reply thread.
+
+When replying to a text event E the reply event's "p" tags should contain all of E's "p" tags as well as the `"pubkey"` of the event being replied to.

+

+        }
+    ]
+}
+```
+
+> [!NOTE]
+> Items sold as an auction are very similar in structure to fixed-price items, with some important differences worth noting.
+
+* The `start_date` can be set to a date in the future if the auction is scheduled to start on that date, or can be omitted if the start date is unknown/hidden. If the start date is not specified, the auction will have to be edited later to set an actual date.
+
+* The auction runs for an initial number of seconds after the `start_date`, specified by `duration`.
+
+### Event `1021`: Bid
+
+```jsonc
+{
+    "content": <int, amount of sats>,
+    "tags": [["e", <event ID of the auction to bid on>]],
+    // other fields...
+}
+```
+
+Bids are simply events of kind `1021` with a `content` field specifying the amount, in the currency of the auction. Bids must reference an auction.
+
+> [!NOTE]
+> Auctions can be edited as many times as desired (they are "addressable events") by the author - even after the start_date, but they cannot be edited after they have received the first bid! This is enforced by the fact that bids reference the event ID of the auction (rather than the product UUID), which changes with every new version of the auctioned product. So a bid is always attached to one "version". Editing the auction after a bid would result in the new product losing the bid!
+
+### Event `1022`: Bid confirmation
+
+**Event Content**:
+
+```json
+{
+    "status": <String, "accepted" | "rejected" | "pending" | "winner">,
+    "message": <String (optional)>,
+    "duration_extended": <int (optional), number of seconds>
+}
+```
+
+**Event Tags**:
+```json
+  "tags": [["e" <event ID of the bid being confirmed>], ["e", <event ID of the auction>]],
+```
+
+Bids should be confirmed by the merchant before being considered as valid by other clients. So clients should subscribe to *bid confirmation* events (kind `1022`) for every auction that they follow, in addition to the actual bids and should check that the pubkey of the bid confirmation matches the pubkey of the merchant (in addition to checking the signature).
+
+The `content` field is a JSON which includes *at least* a `status`. `winner` is how the *winning bid* is replied to after the auction ends and the winning bid is picked by the merchant.
+
+The reasons for which a bid can be marked as `rejected` or `pending` are up to the merchant's implementation and configuration - they could be anything from basic validation errors (amount too low) to the bidder being blacklisted or to the bidder lacking sufficient *trust*, which could lead to the bid being marked as `pending` until sufficient verification is performed. The difference between the two is that `pending` bids *might* get approved after additional steps are taken by the bidder, whereas `rejected` bids can not be later approved.
+
+An additional `message` field can appear in the `content` JSON to give further context as of why a bid is `rejected` or `pending`.
+
+Another thing that can happen is - if bids happen very close to the end date of the auction - for the merchant to decide to extend the auction duration for a few more minutes. This is done by passing a `duration_extended` field as part of a bid confirmation, which would contain a number of seconds by which the initial duration is extended. So the actual end date of an auction is always `start_date + duration + (SUM(c.duration_extended) FOR c in all confirmations`.

+Private Direct Messages
+-----------------------
+
+`draft` `optional`
+
+This NIP defines an encrypted direct messaging scheme using [NIP-44](44.md) encryption and [NIP-59](59.md) seals and gift wraps.
+
+## Direct Message Kind
+
+Kind `14` is a chat message. `p` tags identify one or more receivers of the message.
+
+```jsonc
+{
+  "id": "<usual hash>",
+  "pubkey": "<sender-pubkey>",
+  "created_at": "<current-time>",
+  "kind": 14,
+  "tags": [
+    ["p", "<receiver-1-pubkey>", "<relay-url>"],
+    ["p", "<receiver-2-pubkey>", "<relay-url>"],
+    ["e", "<kind-14-id>", "<relay-url>"] // if this is a reply
+    ["subject", "<conversation-title>"],
+    // rest of tags...
+  ],
+  "content": "<message-in-plain-text>",
+}
+```
+
+`.content` MUST be plain text. Fields `id` and `created_at` are required.
+
+An `e` tag denotes the direct parent message this post is replying to. 
+
+`q` tags MAY be used when citing events in the `.content` with [NIP-21](21.md).
+
+```json
+["q", "<event-id> or <event-address>", "<relay-url>", "<pubkey-if-a-regular-event>"]
+```
+
+Kind `14`s MUST never be signed. If it is signed, the message might leak to relays and become **fully public**.
+
+## File Message Kind
+
+```jsonc
+{
+  "id": "<usual hash>",
+  "pubkey": "<sender-pubkey>",
+  "created_at": "<current-time>",
+  "kind": 15,
+  "tags": [
+    ["p", "<receiver-1-pubkey>", "<relay-url>"],
+    ["p", "<receiver-2-pubkey>", "<relay-url>"],
+    ["e", "<kind-14-id>", "<relay-url>", "reply"], // if this is a reply
+    ["subject", "<conversation-title>"],
+    ["file-type", "<file-mime-type>"],
+    ["encryption-algorithm", "<encryption-algorithm>"],
+    ["decryption-key", "<decryption-key>"],
+    ["decryption-nonce", "<decryption-nonce>"],
+    ["x", "<the SHA-256 hexencoded string of the file>"],
+    // rest of tags...
+  ],
+  "content": "<file-url>"
+}
+```
+
+Kind `15` is used for sending encrypted file event messages:
+
+- `file-type`: Specifies the MIME type of the attached file (e.g., `image/jpeg`, `audio/mpeg`, etc.) before encryption.
+- `encryption-algorithm`: Indicates the encryption algorithm used for encrypting the file. Supported algorithms: `aes-gcm`.
+- `decryption-key`: The decryption key that will be used by the recipient to decrypt the file.
+- `decryption-nonce`: The decryption nonce that will be used by the recipient to decrypt the file.
+- `content`: The URL of the file (`<file-url>`).
+- `x` containing the SHA-256 hexencoded string of the encrypted file.
+- `ox` containing the SHA-256 hexencoded string of the file before encryption.
+- `size` (optional) size of the encrypted file in bytes
+- `dim` (optional) size in pixels in the form `<width>x<height>`
+- `blurhash`(optional) the [blurhash](https://github.com/woltapp/blurhash) to show while the client is loading the file
+- `thumb` (optional) URL of thumbnail with same aspect ratio (encrypted with the same key, nonce)
+- `fallback` (optional) zero or more fallback file sources in case `url` fails (encrypted with the same key, nonce)
+
+Just like kind `14`, kind `15`s MUST never be signed.
+
+## Chat Rooms
+
+The set of `pubkey` + `p` tags defines a chat room. If a new `p` tag is added or a current one is removed, a new room is created with a clean message history.
+
+Clients SHOULD render messages of the same room in a continuous thread.
+
+An optional `subject` tag defines the current name/topic of the conversation. Any member can change the topic by simply submitting a new `subject` to an existing `pubkey` + `p` tags room. There is no need to send `subject` in every message. The newest `subject` in the chat room is the subject of the conversation.
+
+## Encrypting
+
+Following [NIP-59](59.md), the **unsigned** `kind:14` & `kind:15` chat messages must be sealed (`kind:13`) and then gift-wrapped (`kind:1059`) to each receiver and the sender individually.
+
+```js
+{
+  "id": "<usual hash>",
+  "pubkey": randomPublicKey,
+  "created_at": randomTimeUpTo2DaysInThePast(),
+  "kind": 1059, // gift wrap
+  "tags": [
+    ["p", receiverPublicKey, "<relay-url>"] // receiver
+  ],
+  "content": nip44Encrypt(
+    {
+      "id": "<usual hash>",
+      "pubkey": senderPublicKey,
+      "created_at": randomTimeUpTo2DaysInThePast(),
+      "kind": 13, // seal
+      "tags": [], // no tags
+      "content": nip44Encrypt(unsignedKind14, senderPrivateKey, receiverPublicKey),
+      "sig": "<signed by senderPrivateKey>"
+    },
+    randomPrivateKey, receiverPublicKey
+  ),
+  "sig": "<signed by randomPrivateKey>"
+}
+```
+
+The encryption algorithm MUST use the latest version of [NIP-44](44.md).
+
+Clients MUST verify if pubkey of the `kind:13` is the same pubkey on the `kind:14`, otherwise any sender can impersonate others by simply changing the pubkey on `kind:14`.
+
+Clients SHOULD randomize `created_at` in up to two days in the past in both the seal and the gift wrap to make sure grouping by `created_at` doesn't reveal any metadata.
+
+The gift wrap's `p` tag can be the receiver's main pubkey or an alias key created to receive DMs without exposing the receiver's identity.
+
+Clients CAN offer disappearing messages by setting an `expiration` tag in the gift wrap of each receiver or by not generating a gift wrap to the sender's public key
+
+## Publishing
+
+Kind `10050` indicates the user's preferred relays to receive DMs. The event MUST include a list of `relay` tags with relay URIs.
+
+```jsonc
+{
+  "kind": 10050,

+
+Clients SHOULD publish kind `14` events to the `10050`-listed relays. If that is not found that indicates the user is not ready to receive messages under this NIP and clients shouldn't try.
+
+## Relays
+
+It's advisable that relays do not serve `kind:1059` to clients other than the ones tagged in them.
+
+It's advisable that users choose relays that conform to these practices.
+
+Clients SHOULD guide users to keep `kind:10050` lists small (1-3 relays) and SHOULD spread it to as many relays as viable.
+
+## Benefits & Limitations
+
+This NIP offers the following privacy and security features:
+
+1. **No Metadata Leak**: Participant identities, each message's real date and time, event kinds, and other event tags are all hidden from the public. Senders and receivers cannot be linked with public information alone.
+2. **No Public Group Identifiers**: There is no public central queue, channel or otherwise converging identifier to correlate or count all messages in the same group.
+3. **No Moderation**: There are no group admins: no invitations or bans.
+4. **No Shared Secrets**: No secret must be known to all members that can leak or be mistakenly shared
+5. **Fully Recoverable**: Messages can be fully recoverable by any client with the user's private key
+6. **Optional Forward Secrecy**: Users and clients can opt-in for "disappearing messages".
+7. **Uses Public Relays**: Messages can flow through public relays without loss of privacy. Private relays can increase privacy further, but they are not required.
+8. **Cold Storage**: Users can unilaterally opt-in to sharing their messages with a separate key that is exclusive for DM backup and recovery.
+
+The main limitation of this approach is having to send a separate encrypted event to each receiver. Group chats with more than 100 participants should find a more suitable messaging scheme.
+
+## Implementation
+
+Clients implementing this NIP should by default only connect to the set of relays found in their `kind:10050` list. From that they should be able to load all messages both sent and received as well as get new live updates, making it for a very simple and lightweight implementation that should be fast.
+
+When sending a message to anyone, clients must then connect to the relays in the receiver's `kind:10050` and send the events there but can disconnect right after unless more messages are expected to be sent (e.g. the chat tab is still selected). Clients should also send a copy of their outgoing messages to their own `kind:10050` relay set.
+
+## Examples
+
+This example sends the message `Hola, que tal?` from `nsec1w8udu59ydjvedgs3yv5qccshcj8k05fh3l60k9x57asjrqdpa00qkmr89m` to `nsec12ywtkplvyq5t6twdqwwygavp5lm4fhuang89c943nf2z92eez43szvn4dt`.
+

-Event `created_at` Limits
--------------------------
+Comment
+-------
 
 `draft` `optional`
 
-Relays may define both upper and lower limits within which they will consider an event's `created_at` to be acceptable. Both the upper and lower limits MUST be unix timestamps in seconds as defined in [NIP-01](01.md).
+A comment is a threading note always scoped to a root event or an [`I`-tag](73.md).
 
-If a relay supports this NIP, the relay SHOULD send the client an `OK` result saying the event was not stored for the `created_at` timestamp not being within the permitted limits.
+It uses `kind:1111` with plaintext `.content` (no HTML, Markdown, or other formatting).
 
-Client Behavior
----------------
+Comments MUST point to the root scope using uppercase tag names (e.g. `K`, `E`, `A` or `I`)
+and MUST point to the parent item with lowercase ones (e.g. `k`, `e`, `a` or `i`).
 
-Clients SHOULD use the [NIP-11](11.md) `supported_nips` field to learn if a relay uses event `created_at` time limits as defined by this NIP.
+Comments MUST point to the authors when one is available (i.e. tagging a nostr event). `P` for the root scope
+and `p` for the author of the parent item.
 
-Motivation
-----------
+```jsonc
+{
+  "kind": 1111,
+  "content": "<comment>",
+  "tags": [
+    // root scope: event addresses, event ids, or I-tags.
+    ["<A, E, I>", "<address, id or I-value>", "<relay or web page hint>", "<root event's pubkey, if an E tag>"],
+    // the root item kind
+    ["K", "<root kind>"],
 
-This NIP formalizes restrictions on event timestamps as accepted by a relay and allows clients to be aware of relays that have these restrictions.
+    // pubkey of the author of the root scope event
+    ["P", "<root-pubkey>", "relay-url-hint"],
 
-The event `created_at` field is just a unix timestamp and can be set to a time in the past or future. Relays accept and share events dated to 20 years ago or 50,000 years in the future. This NIP aims to define a way for relays that do not want to store events with *any* timestamp to set their own restrictions.
+    // parent item: event addresses, event ids, or i-tags.
+    ["<a, e, i>", "<address, id or i-value>", "<relay or web page hint>", "<parent event's pubkey, if an e tag>"],
+    // parent item kind
+    ["k", "<parent comment kind>"],
 
-_Replaceable events_ can behave rather unexpectedly if the user wrote them - or tried to write them - with a wrong system clock. Persisting an update with a backdated system now would result in the update not getting persisted without a notification and if they did the last update with a forward dated system, they will again fail to do another update with the now correct time.
-
-A wide adoption of this NIP could create a better user experience as it would decrease the amount of events that appear wildly out of order or even from impossible dates in the distant past or future.
-
-Keep in mind that there is a use case where a user migrates their old posts onto a new relay. If a relay rejects events that were not recently created, it cannot serve this use case.

-Python (pseudocode) Example
----------------------------
-
-```python
-import time
-
-TIME = int(time.time())
-LOWER_LIMIT = TIME - (60 * 60 * 24) # Define lower limit as 1 day into the past
-UPPER_LIMIT = TIME + (60 * 15)      # Define upper limit as 15 minutes into the future
-
-if event.created_at not in range(LOWER_LIMIT, UPPER_LIMIT):
-  ws.send('["OK", event.id, False, "invalid: the event created_at field is out of the acceptable range (-24h, +15min) for this relay"]')

+    ["p", "<parent-pubkey>", "relay-url-hint"]
+  ]
+  // other fields
+}
+```
+
+Tags `K` and `k` MUST be present to define the event kind of the root and the parent items.
+
+`I` and `i` tags create scopes for hashtags, geohashes, URLs, and other external identifiers.
+
+The possible values for `i` tags – and `k` tags, when related to an extenal identity – are listed on [NIP-73](73.md).
+Their uppercase versions use the same type of values but relate to the root item instead of the parent one.
+
+`q` tags MAY be used when citing events in the `.content` with [NIP-21](21.md).
+
+```json
+["q", "<event-id> or <event-address>", "<relay-url>", "<pubkey-if-a-regular-event>"]
+```
+
+`p` tags SHOULD be used when mentioning pubkeys in the `.content` with [NIP-21](21.md).
+
+Comments MUST NOT be used to reply to kind 1 notes. [NIP-10](10.md) should instead be followed.

+======
+
+Relay-based Groups
+------------------
+
+`draft` `optional`
+
+This NIP defines a standard for groups that are only writable by a closed set of users. They can be public for reading by external users or not.
+
+Groups are identified by a random string of any length that serves as an _id_.
+
+There is no way to create a group, what happens is just that relays (most likely when asked by users) will create rules around some specific ids so these ids can serve as an actual group, henceforth messages sent to that group will be subject to these rules.
+
+Normally a group will originally belong to one specific relay, but the community may choose to move the group to other relays or even fork the group so it exists in different forms -- still using the same _id_ -- across different relays.
+
+## Relay-generated events
+
+Relays are supposed to generate the events that describe group metadata and group admins. These are _addressable_ events signed by the relay keypair directly, with the group _id_ as the `d` tag.
+
+## Group identifier
+
+A group may be identified by a string in the format `<host>'<group-id>`. For example, a group with _id_ `abcdef` hosted at the relay `wss://groups.nostr.com` would be identified by the string `groups.nostr.com'abcdef`.
+
+Group identifiers must be strings restricted to the characters `a-z0-9-_`, and SHOULD be random in order to avoid name collisions.
+
+When encountering just the `<host>` without the `'<group-id>`, clients MAY infer `_` as the group id, which is a special top-level group dedicated to relay-local discussions.
+
+## The `h` tag
+
+Events sent by users to groups (chat messages, text notes, moderation events etc) MUST have an `h` tag with the value set to the group _id_.
+
+## Timeline references
+
+In order to not be used out of context, events sent to these groups may contain references to previous events seen from the same relay in the `previous` tag. The choice of which previous events to pick belongs to the clients. The references are to be made using the first 8 characters (4 bytes) of any event in the last 50 events seen by the user in the relay, excluding events by themselves. There can be any number of references (including zero), but it's recommended that clients include at least 3 and that relays enforce this.
+
+This is a hack to prevent messages from being broadcasted to external relays that have forks of one group out of context. Relays are expected to reject any events that contain timeline references to events not found in their own database. Clients should also check these to keep relays honest about them.
+
+## Late publication
+
+Relays should prevent late publication (messages published now with a timestamp from days or even hours ago) unless they are open to receive a group forked or moved from another relay.
+
+## Group management
+
+Groups can have any number of users with elevated access. These users are identified by role labels which are arbitrarily defined by the relays (see also the description of `kind:39003`). What each role is capable of not defined in this NIP either, it's a relay policy that can vary. Roles can be assigned by other users (as long as they have the capability to add roles) by publishing a `kind:9000` event with that user's pubkey in a `p` tag and the roles afterwards (even if the user is already a group member a `kind:9000` can be issued and the user roles must just be updated).
+
+The roles supported by the group as to having some special privilege assigned to them should be accessible on the event `kind:39003`, but the relay may also accept other role names, arbitrarily defined by clients, and just not do anything with them.
+
+Users with any roles that have any privilege can be considered _admins_ in a broad sense and be returned in the `kind:39001` event for a group.
+
+## Unmanaged groups
+
+Unmanaged groups are impromptu groups that can be used in any public relay unaware of NIP-29 specifics. They piggyback on relays' natural white/blacklists (or lack of) but aside from that are not actively managed and won't have any admins, group state or metadata events.
+
+In `unmanaged` groups, everybody is considered to be a member.
+
+Unmanaged groups can transition to managed groups, in that case the relay master key just has to publish moderation events setting the state of all groups and start enforcing the rules they choose to.
+
+## Event definitions
+
+These are the events expected to be found in NIP-29 groups.
+
+### Normal user-created events
+
+Groups may accept any event kind, including chats, threads, long-form articles, calendar, livestreams, market announcements and so on. These should be as defined in their respective NIPs, with the addition of the `h` tag.
+
+### User-related group management events
+
+These are events that can be sent by users to manage their situation in a group, they also require the `h` tag.

+Any user can send a kind `9021` event to the relay in order to request admission to the group. Relays MUST reject the request if the user has not been added to the group. The accompanying error message SHOULD explain whether the rejection is final, if the request is pending review, or if some other special handling is relevant (e.g. if payment is required). If a user is already a member, the event MUST be rejected with `duplicate: ` as the error message prefix.
+
+```json
+{
+  "kind": 9021,
+  "content": "optional reason",
+  "tags": [
+    ["h", "<group-id>"],
+    ["code", "<optional-invite-code>"]
+  ]
+}
+```
+
+The optional `code` tag may be used by the relay to preauthorize acceptances in `closed` groups, together with the `kind:9009` `create-invite` moderation event.
+
+- *leave request* (`kind:9022`)
+
+Any user can send one of these events to the relay in order to be automatically removed from the group. The relay will automatically issue a `kind:9001` in response removing this user.
+
+```json
+{
+  "kind": 9022,
+  "content": "optional reason",
+  "tags": [
+    ["h", "<group-id>"]
+  ]
+}
+```
+
+### Group state -- or moderation
+
+These are events expected to be sent by the relay master key or by group admins -- and relays should reject them if they don't come from an authorized admin. They also require the `h` tag.
+
+- *moderation events* (`kinds:9000-9020`) (optional)
+
+Clients can send these events to a relay in order to accomplish a moderation action. Relays must check if the pubkey sending the event is capable of performing the given action based on its role and the relay's internal policy (see also the description of `kind:39003`).
+
+```jsonc
+{
+  "kind": 90xx,
+  "content": "optional reason",
+  "tags": [
+    ["h", "<group-id>"],
+    ["previous", /*...*/]
+  ]
+}
+```
+
+Each moderation action uses a different kind and requires different arguments, which are given as tags. These are defined in the following table:
+
+| kind | name                | tags                                           |
+| ---  | ---                 | ---                                            |
+| 9000 | `put-user`          | `p` with pubkey hex and optional roles         |
+| 9001 | `remove-user`       | `p` with pubkey hex                            |
+| 9002 | `edit-metadata`     | fields from `kind:39000` to be modified        |
+| 9005 | `delete-event`      | `e` with event id hex                          |
+| 9007 | `create-group`      |                                                |
+| 9008 | `delete-group`      |                                                |
+| 9009 | `create-invite`     |                                                |
+
+It's expected that the group state (of who is an allowed member or not, who is an admin and with which permission or not, what are the group name and picture etc) can be fully reconstructed from the canonical sequence of these events.
+
+### Group metadata events
+
+These events contain the group id in a `d` tag instead of the `h` tag. They MUST be created by the relay master key only and a single instance of each (or none) should exist at all times for each group. They are merely informative but should reflect the latest group state (as it was changed by moderation events over time).
+
+- *group metadata* (`kind:39000`) (optional)
+
+This event defines the metadata for the group -- basically how clients should display it. It must be generated and signed by the relay in which is found. Relays shouldn't accept these events if they're signed by anyone else.
+
+If the group is forked and hosted in multiple relays, there will be multiple versions of this event in each different relay and so on.
+
+When this event is not found, clients may still connect to the group, but treat it as having a different status, `unmanaged`,
+
+```jsonc
+{
+  "kind": 39000,
+  "content": "",
+  "tags": [
+    ["d", "<group-id>"],
+    ["name", "Pizza Lovers"],
+    ["picture", "https://pizza.com/pizza.png"],
+    ["about", "a group for people who love pizza"],
+    ["public"], // or ["private"]
+    ["open"] // or ["closed"]
+  ]
+  // other fields...
+}
+```
+
+`name`, `picture` and `about` are basic metadata for the group for display purposes. `public` signals the group can be _read_ by anyone, while `private` signals that only AUTHed users can read. `open` signals that anyone can request to join and the request will be automatically granted, while `closed` signals that members must be pre-approved or that requests to join will be manually handled.
+
+- *group admins* (`kind:39001`) (optional)
+
+Each admin is listed along with one or more roles. These roles SHOULD have a correspondence with the roles supported by the relay, as advertised by the `kind:39003` event.
+
+```jsonc
+{
+  "kind": 39001,
+  "content": "list of admins for the pizza lovers group",
+  "tags": [
+    ["d", "<group-id>"],
+    ["p", "<pubkey1-as-hex>", "ceo"],
+    ["p", "<pubkey2-as-hex>", "secretary", "gardener"],
+    // other pubkeys...
+  ],
+  // other fields...
+}
+```
+
+- *group members* (`kind:39002`) (optional)
+
+It's a list of pubkeys that are members of the group. Relays might choose to not to publish this information, to restrict what pubkeys can fetch it or to only display a subset of the members in it.
+
+Clients should not assume this will always be present or that it will contain a full list of members.
+
+```jsonc
+{
+  "kind": 39002,
+  "content": "list of members for the pizza lovers group",
+  "tags": [
+    ["d", "<group-id>"],
+    ["p", "<admin1>"],
+    ["p", "<member-pubkey1>"],
+    ["p", "<member-pubkey2>"],
+    // other pubkeys...
+  ],
+  // other fields...
+}
+```
+
+- *group roles* (`kind:39003`) (optional)
+
+This is an event that MAY be published by the relay informing users and clients about what are the roles supported by this relay according to its internal logic.
+
+For example, a relay may choose to support the roles `"admin"` and `"moderator"`, in which the `"admin"` will be allowed to edit the group metadata, delete messages and remove users from the group, while the `"moderator"` can only delete messages (or the relay may choose to call these roles `"ceo"` and `"secretary"` instead, the exact role name is not relevant).
+
+The process through which the relay decides what roles to support and how to handle moderation events internally based on them is specific to each relay and not specified here.
+
+```jsonc
+{
+  "kind": 39003,
+  "content": "list of roles supported by this group",
+  "tags": [
+    ["d", "<group-id>"],
+    ["role", "<role-name>", "<optional-description>"],
+    ["role", "<role-name>", "<optional-description>"],
+    // other roles...
+  ],
+  // other fields...
+}
+```
+
+## Implementation quirks
+
+### Checking your own membership in a group
+
+The latest of either `kind:9000` or `kind:9001` events present in a group should tell a user that they are currently members of the group or if they were removed. In case none of these exist the user is assumed to not be a member of the group -- unless the group is `unmanaged`, in which case the user is assumed to be a member.
+
+### Adding yourself to a group
+
+When a group is `open`, anyone can send a `kind:9021` event to it in order to be added, then expect a `kind:9000` event to be emitted confirming that the user was added. The same happens with `closed` groups, except in that case a user may only send a `kind:9021` if it has an invite code.
+
+### Storing your list of groups
+
+A definition for `kind:10009` was included in [NIP-51](51.md) that allows clients to store the list of groups a user wants to remember being in.
+
+### Using `unmanaged` relays
+
+To prevent event leakage, when using `unmanaged` relays, clients should include the [NIP-70](70.md) `-` tag, as just the `previous` tag won't be checked by other `unmanaged` relays.
+
+Groups MAY be named without relay support by adding a `name` to the corresponding tag in a user's `kind 10009` group list.

+-----------
+
+`draft` `optional`
+
+This NIP defines all the ways code collaboration using and adjacent to [`git`](https://git-scm.com/) can be done using Nostr.
+
+## Repository announcements
+
+Git repositories are hosted in Git-enabled servers, but their existence can be announced using Nostr events, as well as their willingness to receive patches, bug reports and comments in general.
+
+```jsonc
+{
+  "kind": 30617,
+  "content": "",
+  "tags": [
+    ["d", "<repo-id>"], // usually kebab-case short name
+    ["name", "<human-readable project name>"],
+    ["description", "brief human-readable project description>"],
+    ["web", "<url for browsing>", ...], // a webpage url, if the git server being used provides such a thing
+    ["clone", "<url for git-cloning>", ...], // a url to be given to `git clone` so anyone can clone it
+    ["relays", "<relay-url>", ...], // relays that this repository will monitor for patches and issues
+    ["r", "<earliest-unique-commit-id>", "euc"],
+    ["maintainers", "<other-recognized-maintainer>", ...],
+    ["t", "<arbitrary string>"], // hashtags labelling the repository
+  ]
+}
+```
+
+The tags `web`, `clone`, `relays`, `maintainers` can have multiple values.
+
+The `r` tag annotated with the `"euc"` marker should be the commit ID of the earliest unique commit of this repo, made to identify it among forks and group it with other repositories hosted elsewhere that may represent essentially the same project. In most cases it will be the root commit of a repository. In case of a permanent fork between two projects, then the first commit after the fork should be used.
+
+Except `d`, all tags are optional.
+
+## Repository state announcements
+
+An optional source of truth for the state of branches and tags in a repository.
+
+```jsonc
+{
+  "kind": 30618,
+  "content": "",
+  "tags": [
+    ["d", "<repo-id>"], // matches the identifier in the coresponding repository announcement
+    ["refs/<heads|tags>/<branch-or-tag-name>","<commit-id>"]
+    ["HEAD", "ref: refs/heads/<branch-name>"]
+  ]
+}
+```
+
+The `refs` tag may appear multiple times, or none.
+
+If no `refs` tags are present, the author is no longer tracking repository state using this event. This approach enables the author to restart tracking state at a later time unlike [NIP-09](09.md) deletion requests.
+
+The `refs` tag can be optionally extended to enable clients to identify how many commits ahead a ref is:
+
+```jsonc
+{
+  "tags": [
+    ["refs/<heads|tags>/<branch-or-tag-name>", "<commit-id>", "<shorthand-parent-commit-id>", "<shorthand-grandparent>", ...],
+  ]
+}
+```
+
+## Patches
+
+Patches can be sent by anyone to any repository. Patches to a specific repository SHOULD be sent to the relays specified in that repository's announcement event's `"relays"` tag. Patch events SHOULD include an `a` tag pointing to that repository's announcement address.
+
+Patches in a patch set SHOULD include a [NIP-10](10.md) `e` `reply` tag pointing to the previous patch.
+
+The first patch revision in a patch revision SHOULD include a [NIP-10](10.md) `e` `reply` to the original root patch.
+
+```jsonc
+{
+  "kind": 1617,
+  "content": "<patch>", // contents of <git format-patch>
+  "tags": [
+    ["a", "30617:<base-repo-owner-pubkey>:<base-repo-id>"],
+    ["r", "<earliest-unique-commit-id-of-repo>"] // so clients can subscribe to all patches sent to a local git repo
+    ["p", "<repository-owner>"],
+    ["p", "<other-user>"], // optionally send the patch to another user to bring it to their attention
+
+    ["t", "root"], // omitted for additional patches in a series
+    // for the first patch in a revision
+    ["t", "root-revision"],
+
+    // optional tags for when it is desirable that the merged patch has a stable commit id
+    // these fields are necessary for ensuring that the commit resulting from applying a patch
+    // has the same id as it had in the proposer's machine -- all these tags can be omitted
+    // if the maintainer doesn't care about these things
+    ["commit", "<current-commit-id>"],
+    ["r", "<current-commit-id>"] // so clients can find existing patches for a specific commit
+    ["parent-commit", "<parent-commit-id>"],
+    ["commit-pgp-sig", "-----BEGIN PGP SIGNATURE-----..."], // empty string for unsigned commit
+    ["committer", "<name>", "<email>", "<timestamp>", "<timezone offset in minutes>"],
+  ]
+}
+```
+
+The first patch in a series MAY be a cover letter in the format produced by `git format-patch`.
+
+## Issues
+
+Issues are Markdown text that is just human-readable conversational threads related to the repository: bug reports, feature requests, questions or comments of any kind. Like patches, these SHOULD be sent to the relays specified in that repository's announcement event's `"relays"` tag. 
+
+Issues may have a `subject` tag, which clients can utilize to display a header. Additionally, one or more `t` tags may be included to provide labels for the issue.
+
+```json
+{
+  "kind": 1621,
+  "content": "<markdown text>",
+  "tags": [
+    ["a", "30617:<base-repo-owner-pubkey>:<base-repo-id>"],
+    ["p", "<repository-owner>"]
+    ["subject", "<issue-subject>"]
+    ["t", "<issue-label>"]
+    ["t", "<another-issue-label>"]
+  ]
+}
+```
+
+## Replies
+
+Replies to either a `kind:1621` (_issue_) or a `kind:1617` (_patch_) event should follow [NIP-22 comment](22.md).
+
+## Status
+
+Root Patches and Issues have a Status that defaults to 'Open' and can be set by issuing Status events.
+
+```jsonc
+{
+  "kind": 1630, // Open
+  "kind": 1631, // Applied / Merged for Patches; Resolved for Issues
+  "kind": 1632, // Closed
+  "kind": 1633, // Draft
+  "content": "<markdown text>",
+  "tags": [
+    ["e", "<issue-or-original-root-patch-id-hex>", "", "root"],
+    ["e", "<accepted-revision-root-id-hex>", "", "reply"], // for when revisions applied
+    ["p", "<repository-owner>"],
+    ["p", "<root-event-author>"],
+    ["p", "<revision-author>"],
+
+    // optional for improved subscription filter efficiency
+    ["a", "30617:<base-repo-owner-pubkey>:<base-repo-id>", "<relay-url>"],
+    ["r", "<earliest-unique-commit-id-of-repo>"]
+
+    // optional for `1631` status
+    ["e", "<applied-or-merged-patch-event-id>", "", "mention"], // for each
+    // when merged
+    ["merge-commit", "<merge-commit-id>"]
+    ["r", "<merge-commit-id>"]
+    // when applied
+    ["applied-as-commits", "<commit-id-in-master-branch>", ...]
+    ["r", "<applied-commit-id>"] // for each
+  ]
+}
+```
+
+The most recent Status event (by `created_at` date) from either the issue/patch author or a maintainer is considered valid.
+
+The Status of a patch-revision is to either that of the root-patch, or `1632` (_Closed_) if the root-patch's Status is `1631` (_Applied/Merged_) and the patch-revision isn't tagged in the `1631` (_Applied/Merged_) event.

+Torrents
+--------
+
+`draft` `optional`
+
+This NIP defined a new `kind 2003` which is a Torrent. 
+
+`kind 2003` is a simple torrent index where there is enough information to search for content and construct the magnet link. No torrent files exist on nostr.
+
+## Tags
+- `x`: V1 BitTorrent Info Hash, as seen in the [magnet link](https://www.bittorrent.org/beps/bep_0053.html) `magnet:?xt=urn:btih:HASH`
+- `file`: A file entry inside the torrent, including the full path ie. `info/example.txt`
+- `tracker`: (Optional) A tracker to use for this torrent
+
+In order to make torrents searchable by general category, you SHOULD include a few tags like `movie`, `tv`, `HD`, `UHD` etc.
+
+## Tag prefixes
+
+Tag prefixes are used to label the content with references, ie. `["i", "imdb:1234"]`
+
+- `tcat`: A comma separated text category path, ie. `["i", "tcat:video,movie,4k"]`, this should also match the `newznab` category in a best effort approach.
+- `newznab`: The category ID from [newznab](https://github.com/Prowlarr/Prowlarr/blob/develop/src/NzbDrone.Core/Indexers/NewznabStandardCategory.cs)
+- `tmdb`: [The movie database](https://www.themoviedb.org/) id.
+- `ttvdb`: [TV database](https://thetvdb.com/) id.
+- `imdb`: [IMDB](https://www.imdb.com/) id.
+- `mal`: [MyAnimeList](https://myanimelist.net/) id.
+- `anilist`: [AniList](https://anilist.co/) id.
+
+A second level prefix should be included where the database supports multiple media types.
+- `tmdb:movie:693134` maps to `themoviedb.org/movie/693134`
+- `ttvdb:movie:290272` maps to `thetvdb.com/movies/dune-part-two`
+- `mal:anime:9253` maps to `myanimelist.net/anime/9253`
+- `mal:manga:17517` maps to `myanimelist.net/manga/17517`
+
+In some cases the url mapping isnt direct, mapping the url in general is out of scope for this NIP, the section above is only a guide so that implementers have enough information to succsesfully map the url if they wish.

+
+## Torrent Comments
+
+A torrent comment is a `kind 2004` event which is used to reply to a torrent event.
+
+This event works exactly like a `kind 1` and should follow `NIP-10` for tagging.

+Draft Events 
+------------
+
+`draft` `optional`
+
+This NIP defines kind `31234` as a private wrap for drafts of any other event kind. 
+
+The draft event is JSON-stringified, [NIP44-encrypted](44.md) to the signer's public key and placed inside the `.content` of the event.
+
+An additional `k` tag identifies the kind of the draft event. 
+
+```js

+  "kind": 31234,
+  "tags": [
+    ["d", "<identifier>"],
+    ["k", "<kind of the draft event>"],

+    ["a", "<anchor event address>", "<relay-url>"],
+  ],
+  "content": nip44Encrypt(JSON.stringify(draft_event)),
+  // other fields
+}
+```
+
+A blanked `.content` means this draft has been deleted by a client but relays still have the event. 
+
+Tags `e` and `a` identify one or more anchor events, such as parent events on replies.   
+
+## Relay List for Private Content
+
+Kind `10013` indicates the user's preferred relays to store private events like Drafts. The event MUST include a list of `relay` URLs in private tags. Private tags are JSON Stringified, NIP-44-encrypted to the signer's keys and placed inside the .content of the event.
+
+```js
+{
+  "kind": 10013,

+  "content": nip44Encrypt(JSON.stringify([
+    ["relay", "wss://myrelay.mydomain.com"]
+  ]))
+  //...other fields
+}
+```
+
+Relays listed in this event SHOULD be authed and only allow downloads to events signed by the authed user.
+
+Clients SHOULD publish kind `10013` events to the author's [NIP-65](65.md) `write` relays.

 ```
 
+### `OK` and `CLOSED` machine-readable prefixes
+
+This NIP defines two new prefixes that can be used in `OK` (in response to event writes by clients) and `CLOSED` (in response to rejected subscriptions by clients):
+
+- `"auth-required: "` - for when a client has not performed `AUTH` and the relay requires that to fulfill the query or write the event.
+- `"restricted: "` - for when a client has already performed `AUTH` but the key used to perform it is still not allowed by the relay or is exceeding its authorization.
+
 ## Protocol flow
 
-At any moment the relay may send an `AUTH` message to the client containing a challenge. After receiving that the client may decide to
-authenticate itself or not. The challenge is expected to be valid for the duration of the connection or until a next challenge is sent by
-the relay.
+At any moment the relay may send an `AUTH` message to the client containing a challenge. The challenge is valid for the duration of the connection or until another challenge is sent by the relay. The client MAY decide to send its `AUTH` event at any point and the authenticated session is valid afterwards for the duration of the connection.
 
-The client may send an auth message right before performing an action for which it knows authentication will be required -- for example, right
-before requesting `kind: 4` chat messages --, or it may do right on connection start or at some other moment it deems best. The authentication
-is expected to last for the duration of the WebSocket connection.
+### `auth-required` in response to a `REQ` message
 
-Upon receiving a message from an unauthenticated user it can't fulfill without authentication, a relay may choose to notify the client. For
-that it can use a `NOTICE` or `OK` message with a standard prefix `"restricted: "` that is readable both by humans and machines, for example:
+Given that a relay is likely to require clients to perform authentication only for certain jobs, like answering a `REQ` or accepting an `EVENT` write, these are some expected common flows:
 
-```json
-["NOTICE", "restricted: we can't serve DMs to unauthenticated users, does your client implement NIP-42?"]
+```
+relay: ["AUTH", "<challenge>"]
+client: ["REQ", "sub_1", {"kinds": [4]}]
+relay: ["CLOSED", "sub_1", "auth-required: we can't serve DMs to unauthenticated users"]
+client: ["AUTH", {"id": "abcdef...", ...}]
+relay: ["OK", "abcdef...", true, ""]
+client: ["REQ", "sub_1", {"kinds": [4]}]
+relay: ["EVENT", "sub_1", {...}]
+relay: ["EVENT", "sub_1", {...}]
+relay: ["EVENT", "sub_1", {...}]
+relay: ["EVENT", "sub_1", {...}]
+...
 ```
 
-or it can return an `OK` message noting the reason an event was not written using the same prefix:
+In this case, the `AUTH` message from the relay could be sent right as the client connects or it can be sent immediately before the `CLOSED` is sent. The only requirement is that _the client must have a stored challenge associated with that relay_ so it can act upon that in response to the `auth-required` `CLOSED` message.
 
-```json
-["OK", <event-id>, false, "restricted: we do not accept events from unauthenticated users, please sign up at https://example.com/"]
+### `auth-required` in response to an `EVENT` message
+
+The same flow is valid for when a client wants to write an `EVENT` to the relay, except now the relay sends back an `OK` message instead of a `CLOSED` message:
+
+```
+relay: ["AUTH", "<challenge>"]
+client: ["EVENT", {"id": "012345...", ...}]
+relay: ["OK", "012345...", false, "auth-required: we only accept events from registered users"]
+client: ["AUTH", {"id": "abcdef...", ...}]
+relay: ["OK", "abcdef...", true, ""]
+client: ["EVENT", {"id": "012345...", ...}]
+relay: ["OK", "012345...", true, ""]

+NIP-44
+======
+
+Encrypted Payloads (Versioned)
+------------------------------
+
+`optional`
+
+The NIP introduces a new data format for keypair-based encryption. This NIP is versioned
+to allow multiple algorithm choices to exist simultaneously. This format may be used for
+many things, but MUST be used in the context of a signed event as described in NIP-01.
+
+*Note*: this format DOES NOT define any `kind`s related to a new direct messaging standard,
+only the encryption required to define one. It SHOULD NOT be used as a drop-in replacement
+for NIP-04 payloads.
+
+## Versions
+
+Currently defined encryption algorithms:
+
+- `0x00` - Reserved
+- `0x01` - Deprecated and undefined
+- `0x02` - secp256k1 ECDH, HKDF, padding, ChaCha20, HMAC-SHA256, base64
+
+## Limitations
+
+Every nostr user has their own public key, which solves key distribution problems present
+in other solutions. However, nostr's relay-based architecture makes it difficult to implement
+more robust private messaging protocols with things like metadata hiding, forward secrecy,
+and post compromise secrecy.
+
+The goal of this NIP is to have a _simple_ way to encrypt payloads used in the context of a signed
+event. When applying this NIP to any use case, it's important to keep in mind your users' threat
+model and this NIP's limitations. For high-risk situations, users should chat in specialized E2EE
+messaging software and limit use of nostr to exchanging contacts.
+
+On its own, messages sent using this scheme have a number of important shortcomings:
+
+- No deniability: it is possible to prove an event was signed by a particular key
+- No forward secrecy: when a key is compromised, it is possible to decrypt all previous conversations
+- No post-compromise security: when a key is compromised, it is possible to decrypt all future conversations
+- No post-quantum security: a powerful quantum computer would be able to decrypt the messages
+- IP address leak: user IP may be seen by relays and all intermediaries between user and relay
+- Date leak: `created_at` is public, since it is a part of NIP-01 event
+- Limited message size leak: padding only partially obscures true message length
+- No attachments: they are not supported
+
+Lack of forward secrecy may be partially mitigated by only sending messages to trusted relays, and asking
+relays to delete stored messages after a certain duration has elapsed.
+
+## Version 2
+
+NIP-44 version 2 has the following design characteristics:
+
+- Payloads are authenticated using a MAC before signing rather than afterwards because events are assumed
+  to be signed as specified in NIP-01. The outer signature serves to authenticate the full payload, and MUST
+  be validated before decrypting.
+- ChaCha is used instead of AES because it's faster and has
+  [better security against multi-key attacks](https://datatracker.ietf.org/doc/draft-irtf-cfrg-aead-limits/).
+- ChaCha is used instead of XChaCha because XChaCha has not been standardized. Also, xChaCha's improved collision
+  resistance of nonces isn't necessary since every message has a new (key, nonce) pair.
+- HMAC-SHA256 is used instead of Poly1305 because polynomial MACs are much easier to forge.
+- SHA256 is used instead of SHA3 or BLAKE because it is already used in nostr. Also BLAKE's speed advantage
+  is smaller in non-parallel environments.
+- A custom padding scheme is used instead of padmé because it provides better leakage reduction for small messages.
+- Base64 encoding is used instead of another encoding algorithm because it is widely available, and is already used in nostr.
+
+### Encryption
+
+1. Calculate a conversation key
+   - Execute ECDH (scalar multiplication) of public key B by private key A
+     Output `shared_x` must be unhashed, 32-byte encoded x coordinate of the shared point
+   - Use HKDF-extract with sha256, `IKM=shared_x` and `salt=utf8_encode('nip44-v2')`
+   - HKDF output will be a `conversation_key` between two users.
+   - It is always the same, when key roles are swapped: `conv(a, B) == conv(b, A)`
+2. Generate a random 32-byte nonce
+   - Always use [CSPRNG](https://en.wikipedia.org/wiki/Cryptographically_secure_pseudorandom_number_generator)
+   - Don't generate a nonce from message content
+   - Don't re-use the same nonce between messages: doing so would make them decryptable,
+     but won't leak the long-term key
+3. Calculate message keys
+   - The keys are generated from `conversation_key` and `nonce`. Validate that both are 32 bytes long
+   - Use HKDF-expand, with sha256, `PRK=conversation_key`, `info=nonce` and `L=76`
+   - Slice 76-byte HKDF output into: `chacha_key` (bytes 0..32), `chacha_nonce` (bytes 32..44), `hmac_key` (bytes 44..76)
+4. Add padding
+   - Content must be encoded from UTF-8 into byte array
+   - Validate plaintext length. Minimum is 1 byte, maximum is 65535 bytes
+   - Padding format is: `[plaintext_length: u16][plaintext][zero_bytes]`
+   - Padding algorithm is related to powers-of-two, with min padded msg size of 32 bytes
+   - Plaintext length is encoded in big-endian as first 2 bytes of the padded blob
+5. Encrypt padded content
+   - Use ChaCha20, with key and nonce from step 3
+6. Calculate MAC (message authentication code)
+   - AAD (additional authenticated data) is used - instead of calculating MAC on ciphertext,
+     it's calculated over a concatenation of `nonce` and `ciphertext`
+   - Validate that AAD (nonce) is 32 bytes
+7. Base64-encode (with padding) params using `concat(version, nonce, ciphertext, mac)`
+
+Encrypted payloads MUST be included in an event's payload, hashed, and signed as defined in NIP 01, using schnorr
+signature scheme over secp256k1.
+
+### Decryption
+
+Before decryption, the event's pubkey and signature MUST be validated as defined in NIP 01. The public key MUST be
+a valid non-zero secp256k1 curve point, and the signature must be valid secp256k1 schnorr signature. For exact
+validation rules, refer to BIP-340.
+
+1. Check if first payload's character is `#`
+   - `#` is an optional future-proof flag that means non-base64 encoding is used
+   - The `#` is not present in base64 alphabet, but, instead of throwing `base64 is invalid`,
+     implementations MUST indicate that the encryption version is not yet supported
+2. Decode base64
+   - Base64 is decoded into `version, nonce, ciphertext, mac`
+   - If the version is unknown, implementations must indicate that the encryption version is not supported
+   - Validate length of base64 message to prevent DoS on base64 decoder: it can be in range from 132 to 87472 chars
+   - Validate length of decoded message to verify output of the decoder: it can be in range from 99 to 65603 bytes
+3. Calculate conversation key
+   - See step 1 of [encryption](#Encryption)
+4. Calculate message keys
+   - See step 3 of [encryption](#Encryption)
+5. Calculate MAC (message authentication code) with AAD and compare
+   - Stop and throw an error if MAC doesn't match the decoded one from step 2
+   - Use constant-time comparison algorithm
+6. Decrypt ciphertext
+   - Use ChaCha20 with key and nonce from step 3
+7. Remove padding
+   - Read the first two BE bytes of plaintext that correspond to plaintext length
+   - Verify that the length of sliced plaintext matches the value of the two BE bytes
+   - Verify that calculated padding from step 3 of the [encryption](#Encryption) process matches the actual padding
+
+### Details
+
+- Cryptographic methods
+  - `secure_random_bytes(length)` fetches randomness from CSPRNG.
+  - `hkdf(IKM, salt, info, L)` represents HKDF [(RFC 5869)](https://datatracker.ietf.org/doc/html/rfc5869)
+    with SHA256 hash function comprised of methods `hkdf_extract(IKM, salt)` and `hkdf_expand(OKM, info, L)`.
+  - `chacha20(key, nonce, data)` is ChaCha20 [(RFC 8439)](https://datatracker.ietf.org/doc/html/rfc8439) with
+    starting counter set to 0.
+  - `hmac_sha256(key, message)` is HMAC [(RFC 2104)](https://datatracker.ietf.org/doc/html/rfc2104).
+  - `secp256k1_ecdh(priv_a, pub_b)` is multiplication of point B by scalar a (`a ⋅ B`), defined in
+    [BIP340](https://github.com/bitcoin/bips/blob/e918b50731397872ad2922a1b08a5a4cd1d6d546/bip-0340.mediawiki).
+    The operation produces a shared point, and we encode the shared point's 32-byte x coordinate, using method
+    `bytes(P)` from BIP340. Private and public keys must be validated as per BIP340: pubkey must be a valid,
+    on-curve point, and private key must be a scalar in range `[1, secp256k1_order - 1]`.
+    NIP44 doesn't do hashing of the output: keep this in mind, because some libraries hash it using sha256.
+    As an example, in libsecp256k1, unhashed version is available in `secp256k1_ec_pubkey_tweak_mul`
+- Operators
+  - `x[i:j]`, where `x` is a byte array and `i, j <= 0` returns a `(j - i)`-byte array with a copy of the
+    `i`-th byte (inclusive) to the `j`-th byte (exclusive) of `x`.
+- Constants `c`:
+  - `min_plaintext_size` is 1. 1 byte msg is padded to 32 bytes.
+  - `max_plaintext_size` is 65535 (64kB - 1). It is padded to 65536 bytes.
+- Functions
+  - `base64_encode(string)` and `base64_decode(bytes)` are Base64 ([RFC 4648](https://datatracker.ietf.org/doc/html/rfc4648), with padding)
+  - `concat` refers to byte array concatenation
+  - `is_equal_ct(a, b)` is constant-time equality check of 2 byte arrays
+  - `utf8_encode(string)` and `utf8_decode(bytes)` transform string to byte array and back
+  - `write_u8(number)` restricts number to values 0..255 and encodes into Big-Endian uint8 byte array
+  - `write_u16_be(number)` restricts number to values 0..65535 and encodes into Big-Endian uint16 byte array
+  - `zeros(length)` creates byte array of length `length >= 0`, filled with zeros
+  - `floor(number)` and `log2(number)` are well-known mathematical methods
+
+### Implementation pseudocode

+
+The file also contains intermediate values. A quick guidance with regards to its usage:
+
+- `valid.get_conversation_key`: calculate conversation_key from secret key sec1 and public key pub2
+- `valid.get_message_keys`: calculate chacha_key, chacha_nonce, hmac_key from conversation_key and nonce
+- `valid.calc_padded_len`: take unpadded length (first value), calculate padded length (second value)
+- `valid.encrypt_decrypt`: emulate real conversation. Calculate pub2 from sec2, verify conversation_key from (sec1, pub2), encrypt, verify payload, then calculate pub1 from sec1, verify conversation_key from (sec2, pub1), decrypt, verify plaintext.
+- `valid.encrypt_decrypt_long_msg`: same as previous step, but instead of a full plaintext and payload, their checksum is provided.
+- `invalid.encrypt_msg_lengths`
+- `invalid.get_conversation_key`: calculating conversation_key must throw an error
+- `invalid.decrypt`: decrypting message content must throw an error

 This NIP defines the verb `COUNT`, which accepts a subscription id and filters as specified in [NIP 01](01.md) for the verb `REQ`. Multiple filters are OR'd together and aggregated into a single count result.

 Counts are returned using a `COUNT` response in the form `{"count": <integer>}`. Relays may use probabilistic counts to reduce compute requirements.

-Nostr Connect
-------------------------
+Nostr Remote Signing
+--------------------
 
-`draft` `optional`
+## Changes
+
+`remote-signer-key` is introduced, passed in bunker url, clients must differentiate between `remote-signer-pubkey` and `user-pubkey`, must call `get_public_key` after connect, nip05 login is removed, create_account moved to another NIP.
 
 ## Rationale
 
 Private keys should be exposed to as few systems - apps, operating systems, devices - as possible as each system adds to the attack surface.
 
-Entering private keys can also be annoying and requires exposing them to even more systems such as the operating system's clipboard that might be monitored by malicious apps.
+This NIP describes a method for 2-way communication between a remote signer and a Nostr client. The remote signer could be, for example, a hardware device dedicated to signing Nostr events, while the client is a normal Nostr client.
 
+## Terminology
 
-## Terms
+- **user**: A person that is trying to use Nostr.
+- **client**: A user-facing application that _user_ is looking at and clicking buttons in. This application will send requests to _remote-signer_.
+- **remote-signer**: A daemon or server running somewhere that will answer requests from _client_, also known as "bunker".
+- **client-keypair/pubkey**: The keys generated by _client_. Used to encrypt content and communicate with _remote-signer_.
+- **remote-signer-keypair/pubkey**: The keys used by _remote-signer_ to encrypt content and communicate with _client_. This keypair MAY be same as _user-keypair_, but not necessarily.
+- **user-keypair/pubkey**: The actual keys representing _user_ (that will be used to sign events in response to `sign_event` requests, for example). The _remote-signer_ generally has control over these keys.
 
-* **App**: Nostr app on any platform that *requires* to act on behalf of a nostr account.
-* **Signer**: Nostr app that holds the private key of a nostr account and *can sign* on its behalf.
+All pubkeys specified in this NIP are in hex format.
 
+## Overview
 
-## `TL;DR`
+1. _client_ generates `client-keypair`. This keypair doesn't need to be communicated to _user_ since it's largely disposable. _client_ might choose to store it locally and they should delete it on logout;
+2. A connection is established (see below), _remote-signer_ learns `client-pubkey`, _client_ learns `remote-signer-pubkey`.
+3. _client_ uses `client-keypair` to send requests to _remote-signer_ by `p`-tagging and encrypting to `remote-signer-pubkey`;
+4. _remote-signer_ responds to _client_ by `p`-tagging and encrypting to the `client-pubkey`.
+5. _client_ requests `get_public_key` to learn `user-pubkey`.
 
+## Initiating a connection
 
-**App** and **Signer** sends ephemeral encrypted messages to each other using kind `24133`, using a relay of choice. 
+There are two ways to initiate a connection:
 
-App prompts the Signer to do things such as fetching the public key or signing events.
+### Direct connection initiated by _remote-signer_
 
-The `content` field must be an encrypted JSONRPC-ish **request** or **response**.
+_remote-signer_ provides connection token in the form:
 
-## Signer Protocol
+```
+bunker://<remote-signer-pubkey>?relay=<wss://relay-to-connect-on>&relay=<wss://another-relay-to-connect-on>&secret=<optional-secret-value>
+```
 
-### Messages
+_user_ passes this token to _client_, which then sends `connect` request to _remote-signer_ via the specified relays. Optional secret can be used for single successfully established connection only, _remote-signer_ SHOULD ignore new attempts to establish connection with old secret.
 
-#### Request
+### Direct connection initiated by the _client_
 
-```json
+_client_ provides a connection token using `nostrconnect://` as the protocol, and `client-pubkey` as the origin. Additional information should be passed as query parameters:
+
+- `relay` (required) - one or more relay urls on which the _client_ is listening for responses from the _remote-signer_.
+- `secret` (required) - a short random string that the _remote-signer_ should return as the `result` field of its response.
+- `perms` (optional) - a comma-separated list of permissions the _client_ is requesting be approved by the _remote-signer_
+- `name` (optional) - the name of the _client_ application
+- `url` (optional) - the canonical url of the _client_ application
+- `image` (optional) - a small image representing the _client_ application
+
+Here's an example:
+
+```
+nostrconnect://83f3b2ae6aa368e8275397b9c26cf550101d63ebaab900d19dd4a4429f5ad8f5?relay=wss%3A%2F%2Frelay1.example.com&perms=nip44_encrypt%2Cnip44_decrypt%2Csign_event%3A13%2Csign_event%3A14%2Csign_event%3A1059&name=My+Client&secret=0s8j2djs&relay=wss%3A%2F%2Frelay2.example2.com
+```
+
+_user_ passes this token to _remote-signer_, which then sends `connect` *response* event to the `client-pubkey` via the specified relays. Client discovers `remote-signer-pubkey` from connect response author. `secret` value MUST be provided to avoid connection spoofing, _client_ MUST validate the `secret` returned by `connect` response.

-## Flows
+## Auth Challenges
 
-The `content` field contains encrypted message as specified by [NIP04](https://github.com/nostr-protocol/nips/blob/master/04.md). The `kind` chosen is `24133`.
+An Auth Challenge is a response that a _remote-signer_ can send back when it needs the _user_ to authenticate via other means. The response `content` object will take the following form:
 
-### Connect
+```json
+{
+    "id": <request_id>,
+    "result": "auth_url",
+    "error": <URL_to_display_to_end_user>
+}
+```
 
-1. User clicks on **"Connect"** button on a website or scan it with a QR code
-2. It will show an URI to open a "nostr connect" enabled **Signer** 
-3. In the URI there is a pubkey of the **App** ie. `nostrconnect://<pubkey>&relay=<relay>&metadata=<metadata>`
-4. The **Signer** will send a message to ACK the `connect` request, along with his public key
+_client_ should display (in a popup or new tab) the URL from the `error` field and then subscribe/listen for another response from the _remote-signer_ (reusing the same request ID). This event will be sent once the user authenticates in the other window (or will never arrive if the user doesn't authenticate).
 
-### Disconnect (from App)
+### Example event signing request with auth challenge
 
-1. User clicks on **"Disconnect"** button on the **App**
-2. The **App** will send a message to the **Signer** with a `disconnect` request
-3. The **Signer** will send a message to ACK the `disconnect` request
+![signing-example-with-auth-challenge](https://i.nostr.build/W3aj.png)
 
-### Disconnect (from Signer)
+## Appendix
 
-1. User clicks on **"Disconnect"** button on the **Signer**
-2. The **Signer** will send a message to the **App** with a `disconnect` request
+### Announcing _remote-signer_ metadata
 
+_remote-signer_ MAY publish it's metadata by using [NIP-05](05.md) and [NIP-89](89.md). With NIP-05, a request to `<remote-signer>/.well-known/nostr.json?name=_` MAY return this:
+```jsonc
+{
+    "names":{
+        "_": <remote-signer-app-pubkey>,
+    },
+    "nip46": {
+        "relays": ["wss://relay1","wss://relay2"...],
+        "nostrconnect_url": "https://remote-signer-domain.example/<nostrconnect>"
+    }
+}
+```
 
-### Get Public Key
+The `<remote-signer-app-pubkey>` MAY be used to verify the domain from _remote-signer_'s NIP-89 event (see below). `relays` SHOULD be used to construct a more precise `nostrconnect://` string for the specific `remote-signer`. `nostrconnect_url` template MAY be used to redirect users to _remote-signer_'s connection flow by replacing `<nostrconnect>` placeholder with an actual `nostrconnect://` string.
 
-1. The **App** will send a message to the **Signer** with a `get_public_key` request
-3. The **Signer** will send back a message with the public key as a response to the `get_public_key` request
-
-### Sign Event
-
-1. The **App** will send a message to the **Signer** with a `sign_event` request along with the **event** to be signed
-2. The **Signer** will show a popup to the user to inspect the event and sign it
-3. The **Signer** will send back a message with the event including the `id` and the schnorr `signature` as a response to the `sign_event` request
-
-### Delegate
-
-1. The **App** will send a message with metadata to the **Signer** with a `delegate` request along with the **conditions** query string and the **pubkey** of the **App** to be delegated.
-2. The **Signer** will show a popup to the user to delegate the **App** to sign on his behalf
-3. The **Signer** will send back a message with the signed [NIP-26 delegation token](https://github.com/nostr-protocol/nips/blob/master/26.md) or reject it
+### Remote signer discovery via NIP-89
 
+_remote-signer_ MAY publish a NIP-89 `kind: 31990` event with `k` tag of `24133`, which MAY also include one or more `relay` tags and MAY include `nostrconnect_url` tag. The semantics of `relay` and `nostrconnect_url` tags are the same as in the section above.
 
+_client_ MAY improve UX by discovering _remote-signers_ using their `kind: 31990` events. _client_ MAY then pre-generate `nostrconnect://` strings for the _remote-signers_, and SHOULD in that case verify that `kind: 31990` event's author is mentioned in signer's `nostr.json?name=_` file as `<remote-signer-app-pubkey>`.

-Nostr Wallet Connect
+Nostr Wallet Connect (NWC)
 --------------------
 
 `draft` `optional`
 
 ## Rationale
 
-This NIP describes a way for clients to access a remote Lightning wallet through a standardized protocol. Custodians may implement this, or the user may run a bridge that bridges their wallet/node and the Nostr Wallet Connect protocol.
+This NIP describes a way for clients to access a remote lightning wallet through a standardized protocol. Custodians may implement this, or the user may run a bridge that bridges their wallet/node and the Nostr Wallet Connect protocol.
 
 ## Terms
 
-* **client**: Nostr app on any platform that wants to pay Lightning invoices.
-* **user**: The person using the **client**, and want's to connect their wallet app to their **client**.
+* **client**: Nostr app on any platform that wants to interact with a lightning wallet.
+* **user**: The person using the **client**, and wants to connect their wallet to their **client**.
 * **wallet service**: Nostr app that typically runs on an always-on computer (eg. in the cloud or on a Raspberry Pi).  This app has access to the APIs of the wallets it serves.
 
 ## Theory of Operation
- 1. **Users** who which to use this NIP to send lightning payments to other nostr users must first acquire a special "connection" URI from their NIP-47 compliant wallet application.  The wallet application may provide this URI using a QR screen, or a pasteable string, or some other means. 
+
+Fundamentally NWC is communication between a **client** and **wallet service** by the means of E2E-encrypted direct messages over a nostr relay. The relay knows the kinds and tags of notes, but not the content of the encrypted payloads. The **user**'s identity key is not used to avoid linking payment activity to the user. Ideally unique keys are used for each individual connection.
+

- 2. The **user** should then copy this URI into their **client(s)** by pasting, or scanning the QR, etc.  The **client(s)** should save this URI and use it later whenever the **user** makes a payment.  The **client** should then request an `info` (13194) event from the relay(s) specified in the URI.  The **wallet service** will have sent that event to those relays earlier, and the relays will hold it as a replaceable event.

The **user** should then copy this URI into their **client(s)** by pasting, or scanning the QR, etc.  The **client(s)** should save this URI and use it later whenever the **user** (or the **client** on the user's behalf) wants to interact with the wallet.  The **client** should then request an `info` (13194) event from the relay(s) specified in the URI.  The **wallet service** will have sent that event to those relays earlier, and the relays will hold it as a replaceable event.  
  
  3. When the **user** initiates a payment their nostr **client** create a `pay_invoice` request, encrypts it using a token from the URI, and sends it (kind 23194) to the relay(s) specified in the connection URI.  The **wallet service** will be listening on those relays and will decrypt the request and then contact the **user's** wallet application to send the payment.  The **wallet service** will know how to talk to the wallet application because the connection URI specified relay(s) that have access to the wallet app API.  
  
- 4. Once the payment is complete the **wallet service** will send an encrypted `response` (kind 23195) to the **user** over the relay(s) in the URI.  
+ 4. Once the payment is complete the **wallet service** will send an encrypted `response` (kind 23195) to the **user** over the relay(s) in the URI.

 ## Events
 
-There are three event kinds:
+There are four event kinds:
 - `NIP-47 info event`: 13194
 - `NIP-47 request`: 23194
 - `NIP-47 response`: 23195
+- `NIP-47 notification event`: 23196
 
-The info event should be a replaceable event that is published by the **wallet service** on the relay to indicate which commands it supports. The content should be
-a plaintext string with the supported commands, space-separated, eg. `pay_invoice get_balance`. Only the `pay_invoice` command is described in this NIP, but other commands might be defined in different NIPs.
+### Info Event
 
-Both the request and response events SHOULD contain one `p` tag, containing the public key of the **wallet service** if this is a request, and the public key of the **user** if this is a response. The response event SHOULD contain an `e` tag with the id of the request event it is responding to.
+The info event should be a replaceable event that is published by the **wallet service** on the relay to indicate which capabilities it supports.

+The content should be a plaintext string with the supported capabilities space-separated, eg. `pay_invoice get_balance notifications`.
+
+If the **wallet service** supports notifications, the info event SHOULD contain a `notifications` tag with the supported notification types space-separated, eg. `payment_received payment_sent`.

+### Request and Response Events

+Both the request and response events SHOULD contain one `p` tag, containing the public key of the **wallet service** if this is a request, and the public key of the **client** if this is a response. The response event SHOULD contain an `e` tag with the id of the request event it is responding to.
+Optionally, a request can have an `expiration` tag that has a unix timestamp in seconds. If the request is received after this timestamp, it should be ignored.

+
+The **wallet service** generates this connection URI with protocol `nostr+walletconnect://` and base path its 32-byte hex-encoded `pubkey`, which SHOULD be unique per client connection.
+
+The connection URI contains the following query string parameters:
 
 - `relay` Required. URL of the relay where the **wallet service** is connected and will be listening for events. May be more than one.
-- `secret` Required. 32-byte randomly generated hex encoded string. The **client** MUST use this to sign events and encrypt payloads when communicating with the **wallet service**.
+- `secret` Required. 32-byte randomly generated hex encoded string. The **client** MUST use this to sign events and encrypt payloads when communicating with the **wallet service**. The **wallet service** MUST use the corresponding public key of this secret to communicate with the **client**.
     - Authorization does not require passing keys back and forth.
     - The user can have different keys for different applications. Keys can be revoked and created at will and have arbitrary constraints (eg. budgets).
     - The key is harder to leak since it is not shown to the user and backed up.
     - It improves privacy because the user's main key would not be linked to their payments.
 - `lud16` Recommended. A lightning address that clients can use to automatically setup the `lud16` field on the user's profile if they have none configured.
 
-The **client** should then store this connection and use it when the user wants to perform actions like paying an invoice. Due to this NIP using ephemeral events, it is recommended to pick relays that do not close connections on inactivity to not drop events.
+The **client** should then store this connection and use it when the user wants to perform actions like paying an invoice. Due to this NIP using ephemeral events, it is recommended to pick relays that do not close connections on inactivity to not drop events, and ideally retain the events until they are either consumed or become stale.
+
+- When the **client** sends or receives a message it will use the `secret` from the connection URI and **wallet service**'s `pubkey` to encrypt or decrypt.
+- When the **wallet service** sends or receives a message it will use its own secret and the corresponding pubkey of the **client's** `secret` to encrypt or decrypt. The **wallet service** SHOULD NOT store the secret it generates for the client and MUST NOT rely on the knowing the **client** secret for general operation.

-0. The user scans the QR code generated by the **wallet service** with their **client** application, they follow a `nostr+walletconnect:` deeplink or configure the connection details manually.
-1. **client** sends an event to the **wallet service** service with kind `23194`. The content is a `pay_invoice` request. The private key is the secret from the connection string above.
+0. The user scans the QR code generated by the **wallet service** with their **client** application, they follow a `nostr+walletconnect://` deeplink or configure the connection details manually.
+1. **client** sends an event to the **wallet service** with kind `23194`. The content is a `pay_invoice` request. The private key is the secret from the connection string above.
 2. **wallet service** verifies that the author's key is authorized to perform the payment, decrypts the payload and sends the payment.
 3. **wallet service** responds to the event by sending an event with kind `23195` and content being a response either containing an error message or a preimage.
 
 ## Using a dedicated relay
 This NIP does not specify any requirements on the type of relays used. However, if the user is using a custodial service it might make sense to use a relay that is hosted by the custodial service. The relay may then enforce authentication to prevent metadata leaks. Not depending on a 3rd party relay would also improve reliability in this case.

+Private Key Encryption
+----------------------
+
+`draft` `optional`
+
+This NIP defines a method by which clients can encrypt (and decrypt) a user's private key with a password.
+
+Symmetric Encryption Key derivation
+-----------------------------------
+
+PASSWORD = Read from the user. The password should be unicode normalized to NFKC format to ensure that the password can be entered identically on other computers/clients.
+
+LOG\_N = Let the user or implementer choose one byte representing a power of 2 (e.g. 18 represents 262,144) which is used as the number of rounds for scrypt. Larger numbers take more time and more memory, and offer better protection:
+
+    | LOG_N | MEMORY REQUIRED | APPROX TIME ON FAST COMPUTER |
+    |-------|-----------------|----------------------------- |
+    | 16    | 64 MiB          | 100 ms                       |
+    | 18    | 256 MiB         |                              |
+    | 20    | 1 GiB           | 2 seconds                    |
+    | 21    | 2 GiB           |                              |
+    | 22    | 4 GiB           |                              |
+
+SALT = 16 random bytes
+
+SYMMETRIC_KEY = scrypt(password=PASSWORD, salt=SALT, log\_n=LOG\_N, r=8, p=1)
+
+The symmetric key should be 32 bytes long.
+
+This symmetric encryption key is temporary and should be zeroed and discarded after use and not stored or reused for any other purpose.
+
+
+Encrypting a private key
+------------------------
+
+The private key encryption process is as follows:
+
+PRIVATE\_KEY = User's private (secret) secp256k1 key as 32 raw bytes (not hex or bech32 encoded!)
+
+KEY\_SECURITY\_BYTE = one of:
+
+*  0x00 - if the key has been known to have been handled insecurely (stored unencrypted, cut and paste unencrypted, etc)
+*  0x01 - if the key has NOT been known to have been handled insecurely (stored unencrypted, cut and paste unencrypted, etc)
+ * 0x02 - if the client does not track this data
+
+ASSOCIATED\_DATA = KEY\_SECURITY\_BYTE
+
+NONCE = 24 byte random nonce
+
+CIPHERTEXT = XChaCha20-Poly1305(
+    plaintext=PRIVATE\_KEY,
+    associated_data=ASSOCIATED\_DATA,
+    nonce=NONCE,
+    key=SYMMETRIC\_KEY
+)
+
+VERSION\_NUMBER = 0x02
+
+CIPHERTEXT_CONCATENATION = concat(
+    VERSION\_NUMBER,
+    LOG\_N,
+    SALT,
+    NONCE,
+    ASSOCIATED\_DATA,
+    CIPHERTEXT
+)
+
+ENCRYPTED\_PRIVATE\_KEY = bech32_encode('ncryptsec', CIPHERTEXT\_CONCATENATION)
+
+The output prior to bech32 encoding should be 91 bytes long.
+
+The decryption process operates in the reverse.
+
+
+Test Data
+---------
+
+## Password Unicode Normalization
+
+The following password input: "ÅΩẛ̣"
+- Unicode Codepoints: U+212B U+2126 U+1E9B U+0323
+- UTF-8 bytes: [0xE2, 0x84, 0xAB, 0xE2, 0x84, 0xA6, 0xE1, 0xBA, 0x9B, 0xCC, 0xA3]
+
+Should be converted into the unicode normalized NFKC format prior to use in scrypt: "ÅΩẛ̣"
+- Unicode Codepoints: U+00C5 U+03A9 U+1E69
+- UTF-8 bytes: [0xC3, 0x85, 0xCE, 0xA9, 0xE1, 0xB9, 0xA9]
+
+## Encryption
+
+The encryption process is non-deterministic due to the random nonce.
+
+## Decryption
+
+The following encrypted private key:
+
+`ncryptsec1qgg9947rlpvqu76pj5ecreduf9jxhselq2nae2kghhvd5g7dgjtcxfqtd67p9m0w57lspw8gsq6yphnm8623nsl8xn9j4jdzz84zm3frztj3z7s35vpzmqf6ksu8r89qk5z2zxfmu5gv8th8wclt0h4p`
+
+When decrypted with password='nostr' and log_n=16 yields the following hex-encoded private key:
+
+`3501454135014541350145413501453fefb02227e449e57cf4d3a3ce05378683`
+
+Discussion
+----------
+
+### On Key Derivation
+
+Passwords make poor cryptographic keys. Prior to use as a cryptographic key, two things need to happen:
+
+1. An encryption key needs to be deterministically created from the password such that is has a uniform functionally random distribution of bits, such that the symmetric encryption algorithm's assumptions are valid, and
+2. A slow irreversible algorithm should be injected into the process, so that brute-force attempts to decrypt by trying many passwords are severely hampered.
+
+These are achieved using a password-based key derivation function. We use scrypt, which has been proven to be maximally memory hard and which several cryptographers have indicated to the author is better than argon2 even though argon2 won a competition in 2015.
+
+### On the symmetric encryption algorithm
+
+XChaCha20-Poly1305 is typically favored by cryptographers over AES and is less associated with the U.S. government.  It (or it's earlier variant without the 'X') is gaining wide usage, is used in TLS and OpenSSH, and is available in most modern crypto libraries.
+
+Recommendations
+---------
+
+It is not recommended that users publish these encrypted private keys to nostr, as cracking a key may become easier when an attacker can amass many encrypted private keys.
+
+It is recommended that clients zero out the memory of passwords and private keys before freeing that memory.

-* `start` (required) inclusive start date in ISO 8601 format (YYYY-MM-DD). Must be less than `end`, if it exists.
-* `end` (optional) exclusive end date in ISO 8601 format (YYYY-MM-DD). If omitted, the calendar event ends on the same date as `start`.

 * `p` (optional, repeated) 32-bytes hex pubkey of a participant, optional recommended relay URL, and participant's role in the meeting

+## Interactive Rooms and Meetings
+-----
+
+`draft` `optional`
+
+Service providers want to offer Interactive Rooms to the Nostr network in such a way that participants can easily log and query by clients. This NIP describes a general framework to advertise rooms and their associated events.
+
+## Concepts
+
+### Interactive Room (kind:30312)
+
+A special event with `kind:30312` "Interactive Room" defines the configuration and properties of a virtual interactive space. Each room has a unique identifier and can host multiple events/meetings.
+
+```jsonc
+{
+  "kind": 30312,
+  "tags": [
+    ["d", "<unique identifier>"],              // Required: Room identifier
+    ["room", "<name of the room>"],            // Required: Display name
+    ["summary", "<description>"],              // Optional: Room description
+    ["image", "<preview image url>"],          // Optional: Room image
+    ["status", "<open, private, closed>"],     // Required: Room accessibility

+    ["relays", "<url>", "<url>", /*...*/]     // Optional: Preferred relays
+  ],
+  "content": ""  // Usually empty, may contain additional metadata
+}
+```
+
+Room properties:
+* MUST be either open, private or closed. Closed means the room is not in operation.
+* MAY specify access control policy for private rooms (e.g. invite-only, payment required)
+* MAY persist when not in use
+* MUST have at least one provider with "Host" role
+* MAY have multiple providers with different roles
+Provider roles (p tags):
+* Host: Full room management capabilities
+* Moderator: Room moderation capabilities
+* Speaker: Allowed to present/speak
+* Optional proof field for role verification
+
+### Room Meeting (kind:30313)
+
+A special event with kind:30313 represents a scheduled or ongoing meeting within a room. It MUST reference its parent room using the d tag.
+
+```jsonc
+{
+  "kind": 30313,
+  "tags": [
+    ["d", "<event-unique-identifier>"],        // Required: Event identifier
+    ["a", "30312:<pubkey>:<room-id>", "wss://nostr.example.com"], // Required: Reference to parent room, 'd' from 30312
+    ["title", "<meeting-title>"],              // Required: Meeting title
+    ["summary", "<description>"],              // Optional: Meeting description
+    ["image", "<preview image url>"],          // Optional: Meeting image

+    ["ends", "<unix timestamp>"],              // Optional: End time
+    ["status", "<planned, live, ended>"],      // Required: Meeting status
+    ["total_participants", "<number>"],        // Optional: Total registered
+    ["current_participants", "<number>"],      // Optional: Currently active
+    ["p", "<pubkey>", "<url>", "<role>"],     // Optional: Participant with role
+  ],
+  "content": ""  // Usually empty, may contain additional metadata
+}
+```
+
+Event properties:
+* MUST reference parent room via d tag
+* MUST have a status (planned/live/ended)
+* MUST have a start time
+* MAY track participant counts
+* MAY include participant roles specific to the event
+Event management:
+* Clients SHOULD update event status regularly when live
+* Events without updates for 1 hour MAY be considered ended
+* starts and ends timestamps SHOULD be updated when status changes

+Wiki
+----
+
+`draft` `optional`
+
+This NIP defines `kind:30818` (an _addressable event_) for descriptions (or encyclopedia entries) of particular subjects, and it's expected that multiple people will write articles about the exact same subjects, with either small variations or completely independent content.
+
+Articles are identified by lowercase, normalized ascii `d` tags.
+
+### Articles
+```json
+{
+  "content": "A wiki is a hypertext publication collaboratively edited and managed by its own audience.",
+  "tags": [
+    ["d", "wiki"],
+    ["title", "Wiki"],
+  ]
+}
+```
+
+### `d` tag normalization rules
+
+- Any non-letter character MUST be converted to a `-`.
+- All letters MUST be converted to lowercase.
+
+### Content
+
+The `content` should be Asciidoc with two extra functionalities: **wikilinks** and **nostr:...** links.
+
+Unlike normal Asciidoc links `http://example.com[]` that link to external webpages, wikilinks `[[]]` link to other articles in the wiki. In this case, the wiki is the entirety of Nostr. Clicking on a wikilink should cause the client to ask relays for events with `d` tags equal to the target of that wikilink.
+
+Wikilinks can take these two forms:
+
+  1. `[[Target Page]]` -- in this case it will link to the page `target-page` (according to `d` tag normalization rules above) and be displayed as `Target Page`;
+  2. `[[target page|see this]]` -- in this case it will link to the page `target-page`, but will be displayed as `see this`.
+
+`nostr:...` links, as per [NIP-21](21.md), should link to profiles or arbitrary Nostr events. Although it is not recommended to link to specific versions of articles -- instead the _wikilink_ syntax should be preferred, since it should be left to the reader and their client to decide what version of any given article they want to read.
+
+### Optional extra tags
+
+  - `title`: for when the display title should be different from the `d` tag.
+  - `summary`: for display in lists.
+  - `a` and `e`: for referencing the original event a wiki article was forked from.
+
+### Merge Requests
+
+Event `kind:818` represents a request to merge from a forked article into the source. It is directed to a pubkey and references the original article and the modified event.
+
+[INSERT EVENT EXAMPLE]
+
+### Redirects
+
+Event `kind:30819` is also defined to stand for "wiki redirects", i.e. if one thinks `Shell structure` should redirect to `Thin-shell structure` they can issue one of these events instead of replicating the content. These events can be used for automatically redirecting between articles on a client, but also for generating crowdsourced "disambiguation" pages ([common in Wikipedia](https://en.wikipedia.org/wiki/Help:Disambiguation)).
+
+[INSERT EVENT EXAMPLE]
+
+How to decide what article to display
+-------------------------------------
+
+As there could be many articles for each given name, some kind of prioritization must be done by clients. Criteria for this should vary between users and clients, but some means that can be used are described below:
+
+### Reactions
+
+[NIP-25](25.md) reactions are very simple and can be used to create a simple web-of-trust between wiki article writers and their content. While just counting a raw number of "likes" is unproductive, reacting to any wiki article event with a `+` can be interpreted as a recommendation for that article specifically and a partial recommendation of the author of that article. When 2 or 3-level deep recommendations are followed, suddenly a big part of all the articles may have some form of tagging.
+
+### Relays
+
+[NIP-51](51.md) lists of relays can be created with the kind 10102 and then used by wiki clients in order to determine where to query articles first and to rank these differently in relation to other events fetched from other relays.
+
+### Contact lists
+
+[NIP-02](02.md) contact lists can form the basis of a recommendation system that is then expanded with relay lists and reaction lists through nested queries. These lists form a good starting point only because they are so widespread.
+
+### Wiki-related contact lists
+
+[NIP-51](51.md) lists can also be used to create a list of users that are trusted only in the context of wiki authorship or wiki curationship.
+
+Forks
+---------
+Wiki-events can tag other wiki-events with a `fork` marker to specify that this event came from a different version. Both `a` and `e` tags SHOULD be used and have the `fork` marker applied, to identify the exact version it was forked from.
+
+Deference
+---------
+Wiki-events can tag other wiki-events with a `defer` marker to indicate that it considers someone else's entry as a "better" version of itself. If using a `defer` marker both `a` and `e` tags SHOULD be used.
+
+This is a stronger signal of trust than a `+` reaction.
+
+This marker is useful when a user edits someone else's entry; if the original author includes the editor's changes and the editor doesn't want to keep/maintain an independent version, the `link` tag could effectively be a considered a "deletion" of the editor's version and putting that pubkey's WoT weight behind the original author's version.
+
+Why Asciidoc?
+-------------
+
+Wikitext is [garbage](nostr:nevent1qqsqt0gcggry60n72uglhuhypdlmr2dm6swjj69jex5v530gcpazlzsprpmhxue69uhhyetvv9ujumn0wdmksetjv5hxxmmdqy28wumn8ghj7un9d3shjtnyv9kh2uewd9hsygpm7rrrljungc6q0tuh5hj7ue863q73qlheu4vywtzwhx42a7j9n5ueneex) and Markdown is not powerful enough (besides being too freeform and unspecified and prone to generate incompatibilities in the future).
+
+Asciidoc has a strict spec, multiple implementations in many languages, and support for features that are very much necessary in a wiki article, like _sidebars_, _tables_ (with rich markup inside cells), many levels of _headings_, _footnotes_, _superscript_ and _subscript_ markup and _description lists_. It is also arguably easier to read in its plaintext format than Markdown (and certainly much better than Wikitext).
+
+# Appendix 1: Merge requests
+Users can request other users to get their entries merged into someone else's entry by creating a `kind:818` event.
+
+```json
+{
+  "content": "I added information about how to make hot ice-creams",
+  "kind": 818,
+  "tags": [
+    [ "a", "30818:<destination-pubkey>:hot-ice-creams", "<relay-url>" ],
+    [ "e", "<version-against-which-the-modification-was-made>", "<relay-url>" ],
+    [ "p", "<destination-pubkey>" ],
+    [ "e", "<version-to-be-merged>", "<relay-url>", "source" ]
+  ]
+}
+```
+
+`.content`: an optional explanation detailing why this merge is being requested.
+`a` tag: tag of the article which should be modified (i.e. the target of this merge request).
+`e` tag: optional version of the article in which this modifications is based
+`e` tag with `source` marker: the ID of the event that should be merged. This event id MUST be of a `kind:30818` as defined in this NIP.
+
+The destination-pubkey is the pubkey being requested to merge something into their article can create [[NIP-25]] reactions that tag the `kind:818` event with `+` or `-`

+The Android signer uses Intents (to accept/reject permissions manually) and Content Resolvers (to accept/reject permissions automatically in background if the user allowed it) to communicate between applications.
+
+To be able to use the Android signer in your application you should add this to your AndroidManifest.xml:
+
+```xml
+<queries>
+  <intent>
+    <action android:name="android.intent.action.VIEW" />
+    <category android:name="android.intent.category.BROWSABLE" />
+    <data android:scheme="nostrsigner" />
+  </intent>
+</queries>
+```
+
+Then you can use this function to check if there's a signer application installed:
+
+```kotlin
+fun isExternalSignerInstalled(context: Context): Boolean {
+  val intent =
+    Intent().apply {
+      action = Intent.ACTION_VIEW
+      data = Uri.parse("nostrsigner:")
+    }
+  val infos = context.packageManager.queryIntentActivities(intent, 0)
+  return infos.size > 0
+}
+```
+
+## Using Intents
+
+To get the result back from the Signer Application you should use `registerForActivityResult` or `rememberLauncherForActivityResult` in Kotlin. If you are using another framework check the documentation of your framework or a third party library to get the result.
+
+```kotlin
+val launcher = rememberLauncherForActivityResult(
+    contract = ActivityResultContracts.StartActivityForResult(),
+    onResult = { result ->
+        if (result.resultCode != Activity.RESULT_OK) {
+            Toast.makeText(
+                context,
+                "Sign request rejected",
+                Toast.LENGTH_SHORT
+            ).show()
+        } else {
+            val result = activityResult.data?.getStringExtra("result")
+            // Do something with result ...
+        }
+    }
+)
+```
+
+Create the Intent using the **nostrsigner** scheme:
+
+```kotlin
+val intent = Intent(Intent.ACTION_VIEW, Uri.parse("nostrsigner:$content"))
+```
+
+Set the Signer package name after you receive the response from **get_public_key** method:
+
+```kotlin
+intent.`package` = "com.example.signer"
+```
+
+If you are sending multiple intents without awaiting you can add some intent flags to sign all events without opening multiple times the signer
+
+```kotlin
+intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP or Intent.FLAG_ACTIVITY_CLEAR_TOP)
+```
+
+If you are developing a signer application them you need to add this to your AndroidManifest.xml so clients can use the intent flags above
+
+```kotlin
+android:launchMode="singleTop"
+```
+
+Signer MUST answer multiple permissions with an array of results
+
+```kotlin
+
+val results = listOf(
+  Result(
+    package = signerPackageName,
+    result = eventSignture,
+    id = intentId
+  )
+)
+
+val json = results.toJson()
+
+intent.putExtra("results", json)
+```
+
+Send the Intent:
+
+```kotlin
+launcher.launch(intent)
+```

+
+## Using Content Resolver
+
+To get the result back from Signer Application you should use contentResolver.query in Kotlin. If you are using another framework check the documentation of your framework or a third party library to get the result.
+
+If the user did not check the "remember my choice" option, the pubkey is not in Signer Application or the signer type is not recognized the `contentResolver` will return null
+
+For the SIGN_EVENT type Signer Application returns two columns "result" and "event". The column event is the signed event json
+
+For the other types Signer Application returns the column "result"
+
+If the user chose to always reject the event, signer application will return the column "rejected" and you should not open signer application

+
+# Usage for Web Applications
+
+You should consider using [NIP-46: Nostr Connect](46.md) for a better experience for web applications. When using this approach, the web app can't call the signer in the background, so the user will see a popup for every event you try to sign.
+
+Since web applications can't receive a result from the intent, you should add a modal to paste the signature or the event json or create a callback url.
+
+If you send the callback url parameter, Signer Application will send the result to the url.
+
+If you don't send a callback url, Signer Application will copy the result to the clipboard.
+
+You can configure the `returnType` to be **signature** or **event**.
+
+Android intents and browser urls have limitations, so if you are using the `returnType` of **event** consider using the parameter **compressionType=gzip** that will return "Signer1" + Base64 gzip encoded event json

+NIP-59
+======
+
+Gift Wrap
+---------
+
+`optional`
+
+This NIP defines a protocol for encapsulating any nostr event. This makes it possible to obscure most metadata
+for a given event, perform collaborative signing, and more.
+
+This NIP *does not* define any messaging protocol. Applications of this NIP should be defined separately.
+
+This NIP relies on [NIP-44](./44.md)'s versioned encryption algorithms.
+
+# Overview
+
+This protocol uses three main concepts to protect the transmission of a target event: `rumor`s, `seal`s, and `gift wrap`s.
+
+- A `rumor` is a regular nostr event, but is **not signed**. This means that if it is leaked, it cannot be verified.
+- A `rumor` is serialized to JSON, encrypted, and placed in the `content` field of a `seal`. The `seal` is then
+  signed by the author of the note. The only information publicly available on a `seal` is who signed it, but not what was said.
+- A `seal` is serialized to JSON, encrypted, and placed in the `content` field of a `gift wrap`.
+
+This allows the isolation of concerns across layers:
+
+- A rumor carries the content but is unsigned, which means if leaked it will be rejected by relays and clients,
+  and can't be authenticated. This provides a measure of deniability.
+- A seal identifies the author without revealing the content or the recipient.
+- A gift wrap can add metadata (recipient, tags, a different author) without revealing the true author.
+
+# Protocol Description
+
+## 1. The Rumor Event Kind
+
+A `rumor` is the same thing as an unsigned event. Any event kind can be made a `rumor` by removing the signature.
+
+## 2. The Seal Event Kind
+
+A `seal` is a `kind:13` event that wraps a `rumor` with the sender's regular key. The `seal` is **always** encrypted
+to a receiver's pubkey but there is no `p` tag pointing to the receiver. There is no way to know who the rumor is for
+without the receiver's or the sender's private key. The only public information in this event is who is signing it.
+
+```json
+{
+  "id": "<id>",
+  "pubkey": "<real author's pubkey>",
+  "content": "<encrypted rumor>",
+  "kind": 13,
+  "created_at": 1686840217,
+  "tags": [],
+  "sig": "<real author's pubkey signature>"
+}
+```
+
+Tags MUST always be empty in a `kind:13`. The inner event MUST always be unsigned.
+
+## 3. Gift Wrap Event Kind
+
+A `gift wrap` event is a `kind:1059` event that wraps any other event. `tags` SHOULD include any information
+needed to route the event to its intended recipient, including the recipient's `p` tag or [NIP-13](13.md) proof of work.
+
+```json
+{
+  "id": "<id>",
+  "pubkey": "<random, one-time-use pubkey>",
+  "content": "<encrypted kind 13>",
+  "kind": 1059,
+  "created_at": 1686840217,
+  "tags": [["p", "<recipient pubkey>"]],
+  "sig": "<random, one-time-use pubkey signature>"
+}
+```
+
+# Encrypting Payloads
+
+Encryption is done following [NIP-44](44.md) on the JSON-encoded event. Place the encryption payload in the `.content`
+of the wrapper event (either a `seal` or a `gift wrap`).
+
+# Other Considerations
+
+If a `rumor` is intended for more than one party, or if the author wants to retain an encrypted copy, a single
+`rumor` may be wrapped and addressed for each recipient individually.
+
+The canonical `created_at` time belongs to the `rumor`. All other timestamps SHOULD be tweaked to thwart
+time-analysis attacks. Note that some relays don't serve events dated in the future, so all timestamps
+SHOULD be in the past.
+
+Relays may choose not to store gift wrapped events due to them not being publicly useful. Clients MAY choose
+to attach a certain amount of proof-of-work to the wrapper event per [NIP-13](13.md) in a bid to demonstrate that
+the event is not spam or a denial-of-service attack.
+
+To protect recipient metadata, relays SHOULD guard access to `kind 1059` events based on user AUTH. When
+possible, clients should only send wrapped events to relays that offer this protection.
+
+To protect recipient metadata, relays SHOULD only serve `kind 1059` events intended for the marked recipient.
+When possible, clients should only send wrapped events to `read` relays for the recipient that implement
+AUTH, and refuse to serve wrapped events to non-recipients.
+
+# An Example
+
+Let's send a wrapped `kind 1` message between two parties asking "Are you going to the party tonight?"
+
+- Author private key: `0beebd062ec8735f4243466049d7747ef5d6594ee838de147f8aab842b15e273`
+- Recipient private key: `e108399bd8424357a710b606ae0c13166d853d327e47a6e5e038197346bdbf45`
+- Ephemeral wrapper key: `4f02eac59266002db5801adc5270700ca69d5b8f761d8732fab2fbf233c90cbd`
+
+Note that this messaging protocol should not be used in practice, this is just an example. Refer to other
+NIPs for concrete messaging protocols that depend on gift wraps.
+
+## 1. Create an event
+
+Create a `kind 1` event with the message, the receivers, and any other tags you want, signed by the author.
+Do not sign the event.
+
+```json
+{

+}
+```
+
+## 2. Seal the rumor
+
+Encrypt the JSON-encoded `rumor` with a conversation key derived using the author's private key and
+the recipient's public key. Place the result in the `content` field of a `kind 13` `seal` event. Sign
+it with the author's key.

+
+Cashu Wallets
+-------------
+
+`draft` `optional`
+
+This NIP defines the operations of a cashu-based wallet.
+
+A cashu wallet is a wallet which information is stored in relays to make it accessible across applications.
+
+The purpose of this NIP is:
+* ease-of-use: new users immediately are able to receive funds without creating accounts with other services.
+* interoperability: users' wallets follows them across applications.
+
+This NIP doesn't deal with users' *receiving* money from someone else, it's just to keep state of the user's wallet.
+
+# High-level flow
+1. A user has a `kind:17375` event that represents a wallet.
+2. A user has `kind:7375` events that represent the unspent proofs of the wallet. -- The proofs are encrypted with the user's private key.
+3. A user has `kind:7376` events that represent the spending history of the wallet -- This history is for informational purposes only and is completely optional.
+
+## Wallet Event
+```jsonc
+{
+    "kind": 17375,
+    "content": nip44_encrypt([
+        [ "privkey", "hexkey" ],
+        [ "mint", "https://mint1" ],
+        [ "mint", "https://mint2" ]
+    ]),
+    "tags": []
+}
+```
+
+The wallet event is an replaceable event `kind:17375`.
+
+Tags:
+* `mint` - Mint(s) this wallet uses -- there MUST be one or more mint tags.
+* `privkey` - Private key used to unlock P2PK ecash. MUST be stored encrypted in the `.content` field. **This is a different private key exclusively used for the wallet, not associated in any way to the user's Nostr private key** -- This is only used for receiving [NIP-61](61.md) nutzaps.
+
+## Token Event
+Token events are used to record unspent proofs.
+
+There can be multiple `kind:7375` events for the same mint, and multiple proofs inside each `kind:7375` event.
+
+```jsonc
+{
+    "kind": 7375,
+    "content": nip44_encrypt({
+        "mint": "https://stablenut.umint.cash",
+        "proofs": [
+            // one or more proofs in the default cashu format
+            {
+                "id": "005c2502034d4f12",
+                "amount": 1,
+                "secret": "z+zyxAVLRqN9lEjxuNPSyRJzEstbl69Jc1vtimvtkPg=",
+                "C": "0241d98a8197ef238a192d47edf191a9de78b657308937b4f7dd0aa53beae72c46"
+            }
+        ],
+        // tokens that were destroyed in the creation of this token (helps on wallet state transitions)
+        "del": [ "token-event-id-1", "token-event-id-2" ]
+    }),
+    "tags": []
+}
+```
+
+ * `.content` is a [NIP-44](44.md) encrypted payload:
+   * `mint`: The mint the proofs belong to.
+   * `proofs`: unencoded proofs
+   * `del`: token-ids that were destroyed by the creation of this token. This assists with state transitions.
+
+When one or more proofs of a token are spent, the token event should be [NIP-09](09.md)-deleted and, if some proofs are unspent from the same token event, a new token event should be created rolling over the unspent proofs and adding any change outputs to the new token event (the change output should include a `del` field).
+
+The `kind:5` _delete event_ created in the [NIP-09](09.md) process MUST have a tag `["k", "7375"]` to allow easy filtering by clients interested in state transitions.
+
+## Spending History Event
+Clients SHOULD publish `kind:7376` events to create a transaction history when their balance changes.
+
+```jsonc
+{
+    "kind": 7376,
+    "content": nip44_encrypt([
+        [ "direction", "in" ], // in = received, out = sent
+        [ "amount", "1" ],
+        [ "e", "<event-id-of-created-token>", "", "created" ]
+    ]),
+    "tags": [
+        [ "e", "<event-id-of-created-token>", "", "redeemed" ]
+    ]
+}
+```
+
+* `direction` - The direction of the transaction; `in` for received funds, `out` for sent funds.
+
+Clients MUST add `e` tags to create references of destroyed and created token events along with the marker of the meaning of the tag:
+* `created` - A new token event was created.
+* `destroyed` - A token event was destroyed.
+* `redeemed` - A [NIP-61](61.md) nutzap was redeemed.
+
+All tags can be [NIP-44](44.md) encrypted. Clients SHOULD leave `e` tags with a `redeemed` marker unencrypted.
+
+Multiple `e` tags can be added, and should be encrypted, except for tags with the `redeemed` marker.
+
+# Flow
+A client that wants to check for user's wallets information starts by fetching `kind:10019` events from the user's relays, if no event is found, it should fall back to using the user's [NIP-65](65.md) relays.
+
+## Fetch wallet and token list
+From those relays, the client should fetch wallet and token events.
+
+`"kinds": [17375, 7375], "authors": ["<my-pubkey>"]`
+
+## Fetch proofs
+
+## Spending token
+If Alice spends 4 sats from this token event
+```jsonc
+{
+    "kind": 7375,
+    "id": "event-id-1",
+    "content": nip44_encrypt({
+        "mint": "https://stablenut.umint.cash",
+        "proofs": [
+            { "id": "1", "amount": 1 },
+            { "id": "2", "amount": 2 },
+            { "id": "3", "amount": 4 },
+            { "id": "4", "amount": 8 },
+        ]
+    }),
+    "tags": []
+}
+```
+
+Her client:
+* MUST roll over the unspent proofs:
+```jsonc
+{
+    "kind": 7375,
+    "id": "event-id-2",
+    "content": nip44_encrypt({
+        "mint": "https://stablenut.umint.cash",

+        ],
+        "del": [ "event-id-1" ]
+    }),
+    "tags": []
+}
+```
+* MUST delete event `event-id-1`
+* SHOULD add the `event-id-1` to the `del` array of deleted token-ids.
+* SHOULD create a `kind:7376` event to record the spend
+```jsonc
+{
+    "kind": 7376,
+    "content": nip44_encrypt([
+        [ "direction", "out" ],
+        [ "amount", "4" ],
+        [ "e", "<event-id-1>", "", "destroyed" ],
+        [ "e", "<event-id-2>", "", "created" ],
+    ]),
+    "tags": []
+}
+```
+
+## Redeeming a quote (optional)
+When creating a quote at a mint, an event can be used to keep the state of the quote ID, which will be used to check when the quote has been paid. These events should be created with an expiration tag [NIP-40](40.md) of 2 weeks (which is around the maximum amount of time a Lightning payment may be in-flight).
+
+However, application developers SHOULD use local state when possible and only publish this event when it makes sense in the context of their application.
+
+```jsonc
+{
+    "kind": 7374,
+    "content": nip44_encrypt("quote-id"),
+    "tags": [
+        [ "expiration", "<expiration-timestamp>" ],
+        [ "mint", "<mint-url>" ]
+    ]
+}
+```
+
+## Appendix 1: Validating proofs
+Clients can optionally validate proofs to make sure they are not working from an old state; this logic is left up to particular implementations to decide when and why to do it, but if some proofs are checked and deemed to have been spent, the client should delete the token and roll over any unspent proof.

+Nutzaps
+-------
+
+`draft` `optional`
+
+A Nutzap is a P2PK Cashu token in which the payment itself is the receipt.
+
+# High-level flow
+Alice wants to nutzap 1 sat to Bob because of an event `event-id-1` she liked.
+
+## Alice nutzaps Bob
+1. Alice fetches event `kind:10019` from Bob to see the mints Bob trusts.
+2. She mints a token at that mint (or swaps some tokens she already had in that mint) P2PK-locked to the pubkey Bob has listed in his `kind:10019`.
+3. She publishes a `kind:9321` event to the relays Bob indicated with the proofs she minted.
+
+## Bob receives the nutzap
+1. At some point, Bob's client fetches `kind:9321` events p-tagging him from his relays.
+2. Bob's client swaps the token into his wallet.

+
+* `kind:10019` is an event that is useful for others to know how to send money to the user.
+* `relay`: relays where the user will be reading token events from. If a user wants to send money to the user, they should write to these relays.
+* `mint`: mints the user is explicitly agreeing to use to receive funds on. Clients SHOULD not send money on mints not listed here or risk burning their money. Additional markers can be used to list the supported base units of the mint.
+* `pubkey`: Public key that MUST be used to P2PK-lock receiving nutzaps -- implementations MUST NOT use the target user's main Nostr public key. This public key corresponds to the `privkey` field encrypted in a user's [nip-60](60.md) _wallet event_.
+
+## Nutzap event
+Event `kind:9321` is a nutzap event published by the sender, p-tagging the recipient. The outputs are P2PK-locked to the public key the recipient indicated in their `kind:10019` event.
+
+Clients MUST prefix the public key they P2PK-lock with `"02"` (for nostr<>cashu compatibility).

+
+# Receiving nutzaps
+
+Clients should REQ for nutzaps:
+* Filtering with `#u` for mints they expect to receive ecash from.
+  * this is to prevent even interacting with mints the user hasn't explicitly signaled.
+* Filtering with `since` of the most recent `kind:7376` event the same user has created.

+
+Upon receiving a new nutzap, the client should swap the tokens into a wallet the user controls, either a [NIP-60](60.md) wallet, their own LN wallet or anything else.
+
+## Updating nutzap-redemption history
+When claiming a token the client SHOULD create a `kind:7376` event and `e` tag the original nutzap event. This is to record that this token has already been claimed (and shouldn't be attempted again) and as signaling to the recipient that the ecash has been redeemed.
+
+Multiple `kind:9321` events can be tagged in the same `kind:7376` event.
+
+```jsonc
+{
+    "kind": 7376,
+    "content": nip44_encrypt([
+        [ "direction", "in" ], // in = received, out = sent

+        [ "p", "<sender-pubkey>" ] // pubkey of the author of the 9321 event (nutzap sender)
+    ]
+}
+```
+
+Events that redeem a nutzap SHOULD be published to the sender's [NIP-65](65.md) "read" relays.
+
+## Verifying a Cashu Zap
+When listing or counting zaps received by any given event, observer clients SHOULD:
+
+* check that the receiving user has issued a `kind:10019` tagging the mint where the cashu has been minted.
+* check that the token is locked to the pubkey the user has listed in their `kind:10019`.
+* look at the `u` tag and check that the token is issued in one of the mints listed in the `kind:10019`.
+* locally verify the DLEQ proof of the tokens being sent.
+
+All these checks can be done offline (as long as the observer has the receiver mints' keyset and their `kind:10019` event), so the process should be reasonably fast.
+
+## Final Considerations
+1. Clients SHOULD guide their users to use NUT-11 (P2PK) and NUT-12 (DLEQ proofs) compatible-mints in their `kind:10019` event to avoid receiving nutzaps anyone can spend.
+2. Clients SHOULD normalize and deduplicate mint URLs as described in NIP-65.
+3. A nutzap event MUST include proofs in one of the mints the recipient has listed in their `kind:10019` and published to the NIP-65 relays of the recipient, failure to do so may result in the recipient donating the tokens to the mint since the recipient might never see the event.

+Request to Vanish
+-----------------
+
+`draft` `optional`
+
+This NIP offers a Nostr-native way to request a complete reset of a key's fingerprint on the web. This procedure is legally binding in some jurisdictions, and thus, supporters of this NIP should truly delete events from their database. 
+
+## Request to Vanish from Relay
+
+Kind `62` requests a specific relay to delete everything, including [NIP-09](09.md) Deletion Events, from the `.pubkey` until its `.created_at`. 
+
+```jsonc
+{
+  "kind": 62,
+  "pubkey": <32-byte hex-encoded public key of the event creator>,
+  "tags": [

+  ],
+  "content": "<reason or note>",
+  //...other fields
+}
+```
+
+The tag list MUST include at least one `relay` value. 
+
+Content MAY include a reason or a legal notice to the relay operator. 
+
+Relays MUST fully delete any events from the `.pubkey` if their service URL is tagged in the event. 
+
+Relays SHOULD delete all [NIP-59](59.md) Gift Wraps that p-tagged the `.pubkey` if their service URL is tagged in the event, deleting all DMs to the pubkey.
+
+Relays MUST ensure the deleted events cannot be re-broadcasted into the relay. 
+
+Relays MAY store the signed request to vanish for bookkeeping.
+
+Paid relays or relays that restrict who can post MUST also follow the request to vanish regardless of the user's status. 
+
+Publishing a deletion request event (Kind `5`) against a request to vanish has no effect. Clients and relays are not obliged to support "unrequest vanish" functionality.
+
+Clients SHOULD send this event to the target relays only. 
+
+## Global Request to Vanish
+
+To request ALL relays to delete everything, the event MUST include a `relay` tag with the value `ALL_RELAYS` in uppercase. 
+
+```jsonc
+{
+  "kind": 62,
+  "pubkey": <32-byte hex-encoded public key of the event creator>,
+  "tags": [
+    ["relay", "ALL_RELAYS"]
+  ],
+  "content": "<reason>",
+  //...other fields
+}
+```
+
+Clients SHOULD broadcast this event to as many relays as possible.

+Chess (Portable Game Notation)
+------------------------------
+
+`draft` `optional`
+
+This NIP defines `kind:64` notes representing chess games in [PGN][pgn_specification] format, which can be read by humans and is also supported by most chess software.
+
+## Note
+
+### Content
+
+The `.content` of these notes is a string representing a [PGN-database][pgn_formal_syntax].
+
+### Notes
+
+```jsonc

+
+## Client Behavior
+
+Clients SHOULD display the content represented as chessboard.
+
+Clients SHOULD publish PGN notes in ["export format"][pgn_export_format] ("strict mode", i.e. created by machines) but expect incoming notes to be in ["import format"][pgn_import_format] ("lax mode", i.e. created by humans).
+
+Clients SHOULD check whether the formatting is valid and all moves comply with chess rules.
+
+Clients MAY include additional tags (e.g. like [`"alt"`](31.md)) in order to represent the note to users of non-supporting clients.
+
+## Relay Behavior
+
+Relays MAY validate PGN contents and reject invalid notes.
+
+
+## Examples
+
+```pgn
+// A game where nothing is known. Game still in progress, game abandoned, or result otherwise unknown. 
+// Maybe players died before a move has been made.

-- Broadcast the event to the WRITE relays of the author
-- Broadcast the event all READ relays of each tagged user
+Clients SHOULD guide users to keep `kind:10002` lists small (2-4 relays of each category).
 
-## Motivation
+### Discoverability
 
-The old model of using a fixed relay list per user centralizes in large relay operators: 
-
-  - Most users submit their posts to the same highly popular relays, aiming to achieve greater visibility among a broader audience
-  - Many users are pulling events from a large number of relays in order to get more data at the expense of duplication
-  - Events are being copied between relays, oftentimes to many different relays
-  
-This NIP allows Clients to connect directly with the most up-to-date relay set from each individual user, eliminating the need of broadcasting events to popular relays. 
-
-## Final Considerations
-
-1. Clients SHOULD guide users to keep `kind:10002` lists small (2-4 relays). 
-
-2. Clients SHOULD spread an author's `kind:10002` event to as many relays as viable. 
-
-3. `kind:10002` events should primarily be used to advertise the user's preferred relays to others. A user's own client may use other heuristics for selecting relays for fetching data.
-
-4. DMs SHOULD only be broadcasted to the author's WRITE relays and to the receiver's READ relays to keep maximum privacy. 
-
-5. If a relay signals support for this NIP in their [NIP-11](11.md) document that means they're willing to accept kind 10002 events from a broad range of users, not only their paying customers or whitelisted group.
-
-6. Clients SHOULD deduplicate connections by normalizing relay URIs according to [RFC 3986](https://datatracker.ietf.org/doc/html/rfc3986#section-6).
+Clients SHOULD spread an author's `kind:10002` event to as many relays as viable, paying attention to relays that, at any moment, serve naturally as well-known public indexers for these relay lists (where most other clients and users are connecting to in order to publish and fetch those).

+Relay Discovery and Liveness Monitoring
+-------------------
+
+`draft` `optional`
+
+You want to find relays. You may want to discover relays based on criteria that's up to date. You may even want to ensure that you have a complete dataset. You probably want to filter relays based on their reported liveness.
+
+In its purest form:
+
+```json
+{
+  "kind": 30166,
+  "created_at": 1722173222,  
+  "content": "{}",
+  "tags": [
+    [ "d", "wss://somerelay.abc/" ]
+  ],
+  "pubkey": "<pubkey>", 
+  "sig": "<signature>",
+  "id": "<eventid>"
+}
+```
+
+This event signals that the relay at `wss://somerelay.abc/` was reported "online" by `<pubkey>` at timestamp `1722173222`. This event **MAY** be extended upon to include more information.
+
+## Kinds
+`NIP-66` defines two (2) event kinds, `30166` and `10166`
+
+| kind  | name                       | description                                                                             |

+| [10166](#k10166) | Relay Monitor Announcement | An RE that stores data that signals the intent of a pubkey to monitor relays and publish `30166` events at a regular _frequency_ |
+
+## Ontology
+- `Relay Operator`: someone who operates a relay 
+- `Monitor`: A pubkey that monitors relays and publishes `30166` events at the frequency specified in their `10166` event.
+- `Ad-hoc Monitor`: A pubkey that monitors relays and publishes `30166` events at an irregular frequency.
+- `Monitor Service`: A group or individual that monitors relays using one or more `Monitors`.
+- `Check`: a specific data point that is tested or aggregated by a monitor.
+
+## `30166`: "Relay Discovery" <a id="k30166"></a>
+
+### Summary
+`30166` is a `NIP-33` addressable event, referred to as a "Relay Discovery" event. These events are optimized with a small footprint for protocol-level relay Discovery.
+
+### Purpose 
+Discovery of relays over nostr. 
+
+### Schema 
+
+#### Content 
+`30166` content fields **SHOULD** include the stringified JSON of the relay's NIP-11 informational document. This data **MAY** be provided for informational purposes only. 
+
+#### `created_at`
+The `created_at` field in a NIP-66 event should reflect the time when the relay liveness (and potentially other data points) was checked.
+
+#### `tags`
+
+##### Meta Tags (unindexed)
+- `rtt-open` The relay's open **round-trip time** in milliseconds.
+- `rtt-read` The relay's read **round-trip time** in milliseconds.
+- `rtt-write` The relay's write **round-trip time** in milliseconds.
+
+_Other `rtt` values **MAY** be present. This NIP should be updated if there is value found in more `rtt` values._
+
+##### Single Letter Tags (indexed)
+- `d` The relay URL/URI. The `#d` tag **must** be included in the `event.tags[]` array. Index position `1` **must** be the relay websocket URL/URI. If a URL it **SHOULD** be [normalized](https://datatracker.ietf.org/doc/html/rfc3986#section-6). For relays not accessible via conventional means but rather by an npub/pubkey, an npub/pubkey **MAY** be used in place of a URL.
+  ```json
+  [ "d", "wss://somerelay.abc/"]
+  ```
+
+- `n`: Network
+  ```json
+  [ "n", "clearnet" ]
+  ```
+
+- `T`: Relay Type. Enumerated [relay type](https://github.com/nostr-protocol/nips/issues/1282) formatted as `PascalCase`
+  ```json
+  ["T", "PrivateInbox" ]
+  ```
+
+- `N`: Supported Nips _From NIP-11 "Informational Document" `nip11.supported_nips[]`_

+  ```
+
+- `R`: Requirements _NIP-11 "Informational Document" `nip11.limitations.payment_required`, `nip11.limitations.auth_required` and/or any other boolean value within `nip11.limitations[]` that is added in the future_
+  ```json
+  [ "R", "payment" ],
+  [ "R", "auth" ],
+  ```
+  Since the nostr protocol does not currently support filtering on whether an indexed tag **is** or **is not** set, to make "public" and "no auth" relays discoverable requires a `!` flag
+
+  ```json
+  [ "R", "!payment" ], //no payment required, is public
+  [ "R", "!auth" ], //no authentication required
+  ```
+
+- `t`: "Topics" _From NIP-11 "Informational Document" `nip11.tags[]`_
+  ```json
+  [ "t", "nsfw" ]
+  ```
+
+- `k`: Accepted/Blocked Kinds [`NIP-22`]
+  ```json
+  [ "k", "0" ],
+  [ "k", "3" ],
+  [ "k", "10002" ]
+  ```
+
+  or for blocked kinds
+
+  ```json
+  [ "k", "!0" ]
+  [ "k", "!3" ],
+  [ "k", "!10002" ]
+  ```
+
+- `g`: `NIP-52` `g` tags (geohash)
+  ```json
+  [ "g", "9r1652whz" ]
+  ```
+
+- `30166` **MAY** be extended with global tags defined by other NIPs that do no collide with locally defined indices, including but not limited to: `p`, `t`, `e`, `a`, `i` and `l/L`. 
+
+#### Robust Example of a `30166` Event
+_Relay was online, and you can filter on a number of different tags_
+```json

+
+## `10166`: "Relay Monitor Announcement" Events <a id="k10166"></a>
+
+### Summary 
+`10166` is a replacable event herein referred to as "Relay Monitor Announcement" events. These events contain information about a publisher's intent to monitor and publish data as `30166` events. This event is optional and is intended for monitors who intend to provide monitoring services at a regular and predictable frequency.
+
+### Purpose 
+To provide a directory of monitors, their intent to publish, their criteria and parameters of monitoring activities. Absence of this event implies the monitor is ad-hoc and does not publish events at a predictable frequency, and relies on mechanisms to infer data integrity, such as web-of-trust.
+
+### Schema
+
+#### Standard Tags
+
+- `frequency` The frequency **in seconds** at which the monitor publishes events. A string-integer at index `1` represents the expected frequency the monitor will publish `30166` events. There should only be `1` frequency per monitor. 
+
+  ```json
+  [ "frequency", "3600" ]
+  ```
+
+- `timeout` (optional) The timeout values for various checks conducted by a monitor. Index `1` is the monitor's timeout in milliseconds. Index `2` describes what test the timeout is used for. If no index `2` is provided, it is inferred that the timeout provided applies to all tests. These values can assist relay operators in understanding data signaled by the monitor in _Relay Discovery Events_. 
+  ```json
+  [ "timeout", "2000", "open" ],
+  [ "timeout", "2000", "read" ],
+  [ "timeout", "3000", "write" ],
+  [ "timeout", "2000", "nip11" ],
+  [ "timeout", "4000", "ssl" ]
+  ```
+
+#### Indexed Tags
+- `c`  "Checks" **SHOULD** be a lowercase string describing the check(s) conducted by a monitor. Due to the rapidly evolving nature of relays, enumeration is organic and not strictly defined. But examples of some checks could be websocket `open/read/write/auth`, `nip11` checks, `dns` and `geo` checks, and and any other checks the monitor may deem useful.. Other checks **MAY** be included. New types of checks **SHOULD** be added to this NIP as they are needed.
+  ```json
+  [ "c", "ws" ],
+  [ "c", "nip11" ],
+  [ "c", "dns" ],
+  [ "c", "geo" ],
+  [ "c", "ssl" ],
+  ```
+
+- `g`: `NIP-52` `g` tags (geohash)
+  ```json
+  [ "g", "9r1652whz" ]
+  ```
+
+- Any other globally defined indexable tags **MAY** be included as found necessary.
+
+### Other Requirements
+Monitors **SHOULD** have the following 
+- A published `0` (NIP-1) event
+- A published `10002` (NIP-65) event that defines the relays the monitor publishes to.
+
+### Robust Example of a `10166` Event
+```json
+{
+  "id": "<eventid>",
+  "pubkey": "<monitor's pubkey>",
+  "created_at": "<created_at  [some recent date ...]>",
+  "signature": "<signature>",
+  "content": "",
+  "tags": [  
+
+    [ "timeout", "open", "5000"  ],
+    [ "timeout", "read", "3000"  ],
+    [ "timeout", "write", "3000" ],
+    [ "timeout", "nip11", "3000" ],
+
+    [ "frequency", "3600" ],
+
+    [ "c", "ws" ],
+    [ "c", "nip11" ],
+    [ "c", "ssl" ],
+    [ "c", "dns" ],
+    [ "c", "geo" ]
+
+    [ "g", "ww8p1r4t8" ]
+  ]
+} 
+```
+
+## Methodology 
+
+### Monitors
+1. A _Relay Monitor_ checks the liveness and potentially other attributes of a relay. 
+
+2. _Relay Monitor_ publishes a kind `30166` note when a relay it is monitoring is online. If the monitor has a `10166` event, events should be published at the frequency defined in their `10166` note. 
+
+_Any pubkey that publishes `30166` events **SHOULD** at a minimum be checking that the relay is available by websocket and behaves like a relay_
+
+### Clients
+1. In most cases, a client **SHOULD** filter on `30166` events using either a statically or dynamically defined monitor's `pubkey` and a `created_at` value respective of the monitor's published `frequency`. If the monitor has no stated frequency, other mechanisms should be employed to determine data integrity.
+
+2. _Relay Liveness_ is subjectively determined by the client, starting with the `frequency` value of a monitor. 
+
+3. The liveness of a _Relay Monitor_ can be subjectively determined by detecting whether the _Relay Monitor_ has published events with respect to `frequency` value of any particular monitor.
+
+4. The reliability and trustworthiness of a _Relay Monitor_ could be established via web-of-trust, reviews or similar mechanisms. 
+
+## Risk Mitigation
+
+- When a client implements `NIP-66` events, the client should have a fallback if `NIP-66` events cannot be located.
+
+- A `Monitor` or `Ad-hoc Monitor` may publish erroneous `30166` events, intentionally or otherwise. Therefor, it's important to program defensively to limit the impact of such events. This can be achieved with web-of-trust, reviews, fallbacks and/or data-aggregation for example.

+-------------------
+
+`draft` `optional`
+
+This NIP defines event kind `20` for picture-first clients. Images must be self-contained. They are hosted externally and referenced using `imeta` tags.
+
+The idea is for this type of event to cater to Nostr clients resembling platforms like Instagram, Flickr, Snapchat, or 9GAG, where the picture itself takes center stage in the user experience.
+
+## Picture Events
+
+Picture events contain a `title` tag and description in the `.content`.
+
+They may contain multiple images to be displayed as a single post.
+
+```jsonc
+{
+  "id": <32-bytes lowercase hex-encoded SHA-256 of the the serialized event data>,
+  "pubkey": <32-bytes lowercase hex-encoded public key of the event creator>,

+    ["g", "<geohash>"],
+
+    // When text is written in the image, add the tag to represent the language
+    ["L", "ISO-639-1"],
+    ["l", "en", "ISO-639-1"]
+  ]
+}
+```
+
+The `imeta` tag `annotate-user` places a user link in the specific position in the image.
+
+Only the following media types are accepted:
+- `image/apng`: Animated Portable Network Graphics (APNG)
+- `image/avif`: AV1 Image File Format (AVIF)
+- `image/gif`: Graphics Interchange Format (GIF)
+- `image/jpeg`: Joint Photographic Expert Group image (JPEG)
+- `image/png`: Portable Network Graphics (PNG)
+- `image/webp`: Web Picture format (WEBP)
+
+Picture events might be used with [NIP-71](71.md)'s kind `22` to display short vertical videos in the same feed.

+Peer-to-peer Order events
+-------------------------
+
+`draft` `optional`
+
+## Abstract
+
+Peer-to-peer (P2P) platforms have seen an upturn in recent years, while having more and more options is positive, in the specific case of p2p, having several options contributes to the liquidity split, meaning sometimes there's not enough assets available for trading. If we combine all these individual solutions into one big pool of orders, it will make them much more competitive compared to centralized systems, where a single authority controls the liquidity.
+
+This NIP defines a simple standard for peer-to-peer order events, which enables the creation of a big liquidity pool for all p2p platforms participating.
+
+## The event
+
+Events are [addressable events](01.md#kinds) and use `38383` as event kind, a p2p event look like this:
+
+```json

+Protected Events
+----------------
+
+`draft` `optional`
+
+When the `"-"` tag is present, that means the event is "protected".
+
+A protected event is an event that can only be published to relays by its author. This is achieved by relays ensuring that the author is [authenticated](42.md) before publishing their own events or by just rejecting events with `["-"]` outright.
+
+The default behavior of a relay MUST be to reject any event that contains `["-"]`.
+
+Relays that want to accept such events MUST first require that the client perform the [NIP-42](42.md) `AUTH` flow and then check if the authenticated client has the same pubkey as the event being published and only accept the event in that case.
+
+## The tag
+
+The tag is a simple tag with a single item: `["-"]`. It may be added to any event.
+
+## Example flow
+
+- User `79be667ef9dcbbac55a06295ce870b07029bfcdb2dce28d959f2815b16f81798` connects to relay `wss://example.com`:
+
+```jsonc

+```
+
+## Why
+
+There are multiple circumstances in which it would be beneficial to prevent the unlimited spreading of an event through all relays imaginable and restrict some to only a certain demographic or to a semi-closed community relay. Even when the information is public it may make sense to keep it compartimentalized across different relays.
+
+It's also possible to create closed access feeds with this when the publisher has some relationship with the relay and trusts the relay to not release their published events to anyone.
+
+Even though it's ultimately impossible to restrict the spread of information on the internet (for example, one of the members of the closed group may want to take an event intended to be restricted and republish it to other relays), most relays would be happy to not facilitate the acts of these so-called "pirates", in respect to the original decision of the author and therefore gladly reject these republish acts if given the means to.
+
+This NIP gives these authors and relays the means to clearly signal when a given event is not intended to be republished by third parties.

+Video Events
+------------
+
+`draft` `optional`
+
+This specification defines _video_ events representing a dedicated post of externally hosted content.
+
+Unlike a `kind:1` event with a video attached, video events are meant to contain all additional metadata concerning the subject media and to be surfaced in video-specific clients rather than general micro-blogging clients. The thought is for events of this kind to be referenced in a Netflix, YouTube, or TikTok like nostr client where the video itself is at the center of the experience.
+
+## Video Events
+
+There are two types of video events represented by different kinds: _normal_ and _short_ video events. This is meant to allow clients to cater to each as the viewing experience for longer, mostly horizontal (landscape) videos is often different than that of short-form, mostly vertical (portrait), videos ("stories", "reels", "shorts" etc).
+
+Nothing except cavaliership and common sense prevents a _short_ video from being long, or a _normal_ video from being vertical, and that may or may not be justified, it's mostly a stylistic qualitative difference, not a question of actual raw size.
+
+#### Format
+
+The format uses a _regular event_ kind `21` for _normal_ videos and `22` for _short_ videos.
+
+The `.content` of these events is a summary or description on the video content.
+
+The primary source of video information is the `imeta` tags which is defined in [NIP-92](92.md)
+
+Each `imeta` tag can be used to specify a variant of the video by the `dim` & `m` properties.
+
+Example:
+```json
+[
+  ["imeta",
+    "dim 1920x1080",
+    "url https://myvideo.com/1080/12345.mp4",
+    "x 3093509d1e0bc604ff60cb9286f4cd7c781553bc8991937befaacfdc28ec5cdc",
+    "m video/mp4",
+    "image https://myvideo.com/1080/12345.jpg",
+    "image https://myotherserver.com/1080/12345.jpg",
+    "fallback https://myotherserver.com/1080/12345.mp4",
+    "fallback https://andanotherserver.com/1080/12345.mp4",
+    "service nip96",
+  ],
+  ["imeta",
+    "dim 1280x720",
+    "url https://myvideo.com/720/12345.mp4",
+    "x e1d4f808dae475ed32fb23ce52ef8ac82e3cc760702fca10d62d382d2da3697d",
+    "m video/mp4",
+    "image https://myvideo.com/720/12345.jpg",
+    "image https://myotherserver.com/720/12345.jpg",
+    "fallback https://myotherserver.com/720/12345.mp4",
+    "fallback https://andanotherserver.com/720/12345.mp4",
+    "service nip96",
+  ],
+  ["imeta",
+    "dim 1280x720",
+    "url https://myvideo.com/720/12345.m3u8",
+    "x 704e720af2697f5d6a198ad377789d462054b6e8d790f8a3903afbc1e044014f",
+    "m application/x-mpegURL",
+    "image https://myvideo.com/720/12345.jpg",
+    "image https://myotherserver.com/720/12345.jpg",
+    "fallback https://myotherserver.com/720/12345.m3u8",
+    "fallback https://andanotherserver.com/720/12345.m3u8",
+    "service nip96",
+  ],
+]
+```
+
+Where `url` is the primary server url and `fallback` are other servers hosting the same file, both `url` and `fallback` should be weighted equally and clients are recommended to use any of the provided video urls.
+
+The `image` tag contains a preview image (at the same resolution). Multiple `image` tags may be used to specify fallback copies in the same way `fallback` is used for `url`.
+
+Additionally `service nip96` may be included to allow clients to search the authors NIP-96 server list to find the file using the hash.
+

+* `published_at`, for the timestamp in unix seconds (stringified) of the first time the video was published
+* `duration` (optional) video duration in seconds

+Previously kind 1 events were used for posts in communities, with an "a" tag pointing to the community. For backwards compatibility, clients MAY still query for kind 1 events, but SHOULD NOT use them for new posts. Instead, clients SHOULD use kind 1111 events with the `A` and `a` tags as described above.
+
+# Moderation
+
+Anyone may issue an approval event to express their opinion that a post is appropriate for a community. Clients MAY choose which approval events to honor, but SHOULD at least use ones published by the group's defined moderators.
+
+An approval event MUST include one or more community `a` tags, an `e` or `a` tag pointing to the post, and the `p` tag of the author of the post (for approval notifications). `a` tag prefixes can be used to disambiguate between community and replaceable event pointers (community `a` tags always begin with `34550`).
+
+The event SHOULD also include the JSON-stringified `post request` event inside the `.content`, and a `k` tag with the original post's event kind to allow filtering of approved posts by kind.
+
+Moderators MAY request deletion of their approval of a post at any time using [NIP-09 event deletion requests](09.md).

 It's recommended that multiple moderators approve posts to avoid deleting them from the community when a moderator is removed from the owner's list. In case the full list of moderators must be rotated, the new moderator set must sign new approvals for posts in the past or the community will restart. The owner can also periodically copy and re-sign of each moderator's approval events to make sure posts don't disappear with moderators.
 
-Post Approvals of replaceable events can be created in three ways: (i) by tagging the replaceable event as an `e` tag if moderators want to approve each individual change to the repleceable event; (ii) by tagging the replaceable event as an `a` tag if the moderator authorizes the replaceable event author to make changes without additional approvals and (iii) by tagging the replaceable event with both its `e` and `a` tag which empowers clients to display the original and updated versions of the event, with appropriate remarks in the UI.

+
+Negentropy Syncing
+------------------
+
+`draft` `optional`
+
+This document describes a protocol extension for syncing events. It works for both client-relay and relay-relay scenarios. If both sides of the sync have events in common, then this protocol will use less bandwidth than transferring the full set of events (or even just their IDs).
+
+It is a Nostr-friendly wrapper around the [Negentropy](https://github.com/hoytech/negentropy) protocol, which uses a technique called [Range-Based Set Reconciliation](https://logperiodic.com/rbsr.html).
+
+Since Negentropy is a binary protocol, this wrapper hex-encodes its messages. The specification for Negentropy Protocol V1 is attached as an appendix to this NIP below.
+
+## High-Level Protocol Description
+
+We're going to call the two sides engaged in the sync the client and the relay (even though the initiator could be another relay instead of a client).
+
+* (1) Client (initiator) chooses a filter, and retrieves the set of events that it has locally that match this filter (or uses a cache), and constructs an initial message.
+* (2) Client sends a `NEG-OPEN` message to the relay, which includes the filter and the initial message.
+* (3) Relay selects the set of events that it has locally that match the filter (or uses a cache).
+* (4) Relay constructs a response and returns it to the client in a `NEG-MSG` message.
+* (5) Client parses the message to learn about IDs it has (and relay needs) and IDs it needs (and relay has).
+  * If client wishes to continue, then it constructs a new message and sends it to the relay in a `NEG-MSG` message. Goto step 4.
+  * If client wishes to stop, then it sends a `NEG-CLOSE` message or disconnects the websocket.
+
+The above protocol only results in the client learning about IDs it has/needs, and does not actually transfer events. Given these IDs, the client can upload events it has with `EVENT`, and/or download events it needs with `REQ`. This can be performed over the same websocket connection in parallel with subsequent `NEG-MSG` messages. If a client is only interested in determining the number of unique events (ie, reaction counts), it may choose to not download/upload at all.
+
+## Nostr Messages
+
+### Initial message (client to relay):
+
+```jsonc
+[
+    "NEG-OPEN",
+    <subscription ID string>,
+    <filter>,
+    <initialMessage, hex-encoded>
+]
+```
+
+* The subscription ID is used by each side to identify which query a message refers to. It only needs to be long enough to distinguish it from any other concurrent subscriptions on this websocket connection (an integer that increments once per `NEG-OPEN` is fine). Subscription IDs are in a separate namespace from `REQ` subscription IDs. If a `NEG-OPEN` is issued for a currently open subscription ID, the existing subscription is first closed.
+* The filter is as described in [NIP-01](01.md).
+* `initialMessage` is the initial Negentropy binary message, hex-encoded. See appendix.
+
+### Error message (relay to client):
+
+If a request cannot be serviced by the relay, an error is returned to the client:
+
+```jsonc
+[
+    "NEG-ERR",
+    <subscription ID string>,
+    <reason code string>
+]
+```
+
+Error reasons are the same format as in NIP-01. They should begin with a machine-readable single-word prefix, followed by a `:` and then a human-readable message with more information.
+
+The current suggested error reasons are
+
+* `blocked`
+  * Relays can optionally reject queries that would require them to process too many records, or records that are too old
+  * The maximum number of records that can be processed can optionally be returned as the 4th element in the response
+  * Example: `blocked: this query is too big`
+* `closed`
+  * Because the `NEG-OPEN` queries may be stateful, relays may choose to time-out inactive queries to recover memory resources
+  * Example: `closed: you took too long to respond!`
+
+After a `NEG-ERR` is issued, the subscription is considered to be closed.
+
+### Subsequent messages (bidirectional):
+
+Relay and client alternate sending each other `NEG-MSG`s:
+
+```jsonc
+[
+    "NEG-MSG",
+    <subscription ID string>,
+    <message, hex-encoded>
+]
+```
+
+* `message` is a Negentropy binary message, hex-encoded. Both message directions use the same format. See appendix.
+
+### Close message (client to relay):
+
+When finished, the client should tell the relay it can release its resources with a `NEG-CLOSE`:
+
+```jsonc
+[
+    "NEG-CLOSE",
+    <subscription ID string>
+]
+```
+
+
+## Appendix: Negentropy Protocol V1
+
+### Preparation
+
+There are two protocol participants: Client and server. The client creates an initial message and transmits it to the server, which replies with its own message in response. The client continues querying the server until it is satisifed, and then terminates the protocol. Messages in either direction have the same format.
+
+Each participant has a collection of records. A records consists of a 64-bit numeric timestamp and a 256-bit ID. Each participant starts by sorting their items according to timestamp, ascending. If two timestamps are equal then items are sorted lexically by ID, ascending by first differing byte. Items may not use the max uint64 value (`2**64 - 1`) as a timestamp since this is reserved as a special "infinity" value.
+
+The goal of the protocol is for the client to learn the set of IDs that it has and the server does not, and the set of items that the server has and it does not.
+
+### `Varint`
+
+Varints (variable-sized unsigned integers) are represented as base-128 digits, most significant digit first, with as few digits as possible. Bit eight (the high bit) is set on each byte except the last.
+
+    Varint := <Digit+128>* <Digit>
+
+### `Id`
+
+IDs are represented as byte-strings of length `32`:
+
+    Id := Byte{32}
+
+### `Message`
+
+A reconciliation message is a protocol version byte followed by an ordered list of ranges:
+
+    Message := <protocolVersion (Byte)> <Range>*
+
+The current protocol version is 1, represented by the byte `0x61`. Protocol version 2 will be `0x62`, and so forth. If a server receives a message with a protocol version that it cannot handle, it should reply with a single byte containing the highest protocol version it supports, allowing the client to downgrade and retry its message.
+
+Each Range corresponds to a contiguous section of the timestamp/ID space. The first Range starts at timestamp 0 and an ID of 0 bytes. Ranges are always adjacent (no gaps). If the last Range doesn't end at the special infinity value, an implicit `Skip` to infinity Range is appended. This means that the list of Ranges always covers the full timestamp/ID space.
+
+### `Range`
+
+A Range consists of an upper bound, a mode, and a payload:
+
+    Range := <upperBound (Bound)> <mode (Varint)> <payload (Skip | Fingerprint | IdList)>
+
+The contents of the payload is determined by mode:
+
+* If `mode = 0`, then payload is `Skip`, meaning the sender does not wish to process this Range further. This payload is empty:
+
+      Skip :=
+
+* If `mode = 1`, then payload is a `Fingerprint`, which is a [digest](#fingerprint-algorithm) of all the IDs the sender has within the Range:
+
+      Fingerprint := Byte{16}
+
+* If `mode = 2`, the payload is `IdList`, a variable-length list of all IDs the sender has within the Range:
+
+      IdList := <length (Varint)> <ids (Id)>*
+
+
+### `Bound`
+
+Each Range is specified by an *inclusive* lower bound and an *exclusive* upper bound. As defined above, each Range only includes an upper bound: the lower bound of a Range is the upper bound of the previous Range, or 0 timestamp/0 ID for the first Range.
+
+A Bound consists of an encoded timestamp and a variable-length disambiguating prefix of an ID (in case multiple items have the same timestamp):
+
+    Bound := <encodedTimestamp (Varint)> <length (Varint)> <idPrefix (Byte)>*
+
+* The timestamp is encoded specially. The infinity timestamp is encoded as `0`. All other values are encoded as `1 + offset`, where offset is the difference between this timestamp and the previously encoded timestamp. The initial offset starts at `0` and resets at the beginning of each message.
+
+  Offsets are always non-negative since the upper bound's timestamp is greater than or equal to the lower bound's timestamp, ranges in a message are always encoded in ascending order, and ranges never overlap.
+
+* The size of `idPrefix` is encoded in `length`, and can be between `0` and `32` bytes, inclusive. This allows implementations to use the shortest possible prefix to separate the first record of this Range from the last record of the previous Range. If these records' timestamps differ, then the length should be 0, otherwise it should be the byte-length of their common ID-prefix plus 1.
+
+  If the `idPrefix` length is less than `32` then the omitted trailing bytes are implicitly 0 bytes.
+
+
+### Fingerprint Algorithm
+
+The fingerprint of a Range is computed with the following algorithm:
+
+* Compute the addition mod 2<sup>256</sup> of the element IDs (interpreted as 32-byte little-endian unsigned integers)
+* Concatenate with the number of elements in the Range, encoded as a [Varint](#varint)
+* Hash with SHA-256
+* Take the first 16 bytes

+Relay Management API
+--------------------
+
+`draft` `optional`
+
+Relays may provide an API for performing management tasks. This is made available as a JSON-RPC-like request-response protocol over HTTP, on the same URI as the relay's websocket.
+
+When a relay receives an HTTP(s) request with a `Content-Type` header of `application/nostr+json+rpc` to a URI supporting WebSocket upgrades, it should parse the request as a JSON document with the following fields:
+
+```json
+{
+  "method": "<method-name>",
+  "params": ["<array>", "<of>", "<parameters>"]
+}
+```
+
+Then it should return a response in the format
+
+```json

+  "error": "<optional error message, if the call has errored>"
+}

+Ecash Mint Discoverability
+--------------------------------
+
+`draft` `optional`
+
+This NIP describes `kind:38173`, `kind:38172` and `kind:38000`: a way to discover ecash mints, their capabilities, and people who recommend them.
+
+## Rationale
+
+Nostr's discoverability and transparent event interaction is one of its most interesting/novel mechanics.
+This NIP provides a simple way for users to discover ecash mints recommended by other users and to interact with them.
+
+### Parties involved
+
+There are three actors to this workflow:
+
+* An ecash mint operator, announces their mint and its capabilities.
+    * Publishes `kind:38173` or `kind:38172`, detailing how to connect to it and its capabilities.
+* user A, who recommends an ecash mint
+    * Publishes `kind:38000`
+* user B, who seeks a recommendation for an ecash mint
+    * Queries for `kind:38000` and, based on results, queries for `kind:38173`/`kind:38172`
+
+## Events
+
+### Recommendation event
+```json
+{
+  "kind": 38000,
+  "pubkey": <recommender-user-pubkey>,
+  "tags": [
+    ["k", "38173"],
+    ["d", "<d-identifier>"],
+    ["u", <recommended-fedimint-invite-code>],
+    ["a", "38173:fedimint-pubkey:<d-identifier>", "wss://relay1"]
+  ],
+  "content": "I trust this mint with my life"
+}
+```
+
+The recommendation event is a parameterized-replacable event so that a user can change edit their recommendation without creating a new event.
+
+The `d` tag in `kind:38000` is the `kind:38173`/`kind:38172` event identifier this event is recommending, if no event exists, the `d` tag can still be calculated from the mint's pubkey/id.
+The `k` tag is the kind number that corresponds to the event kind that the user is recommending, in this case `kind:38173` for fedimints and `kind:38172` for cashu mints.
+
+Optional `u` tags can be added to give a recommend way to connect to the mint.
+The value of the tag is the URL or invite code of the ecash mint.
+Multiple `u` tags can appear on the same `kind:38000`.
+
+`a` tags are used to point to the `kind:38173`/`kind:38172` event of the ecash mint.
+The first value of the tag is the `kind:38173`/`kind:38172` event identifier, the second value of the tag is a relay hint.
+This is used to correctly point to the mint's `kind:38173`/`kind:38172` event in case there are duplicates claiming to be the same mint.
+
+The content can be used to give a review.
+
+## Ecash Mint Information
+
+Cashu mints SHOULD publish `kind:38172` events to announce their capabilities and how to connect to them.
+
+For cashu mints, the `u` tag SHOULD be the URL to the cashu mint and it should list the nuts that the cashu mint supports.
+
+The `d` tag SHOULD be the mint's pubkey (found when querying `/v1/info`), this way users can query by pubkey and find the mint announcement.
+
+An `n` tag SHOULD be added to signify the network the cashu mint is on (either `mainnet`, `testnet`, `signet`, or `regtest`)
+
+```json
+{
+  "kind": 38172,
+  "pubkey": "<application-pubkey>",
+  "content": "<optional-kind:0-style-metadata>",
+  "tags": [
+    ["d", <cashu mint pubkey>],
+    ["u", "https://cashu.example.com"],
+    ["nuts", "1,2,3,4,5,6,7"],
+    ["n", "mainnet"]
+  ]
+}
+```
+
+Fedimints SHOULD publish `kind:38173` events to announce their capabilities and how to connect to them.
+
+For fedimints, it should list all known fedimint invite codes in `u` tags and it should list the modules it supports.
+
+The `d` tag SHOULD be the federation id, this way users can query by federation id and find the fedimint announcement.
+
+An `n` tag SHOULD be added to signify the network the fedimint is on (either `mainnet`, `testnet`, `signet`, or `regtest`)
+
+```json
+{
+  "kind": 38173,
+  "pubkey": "<application-pubkey>",
+  "content": "<optional-kind:0-style-metadata>",
+  "tags": [
+    ["d", <federation-id>],
+    ["u", "fed11abc.."],
+    ["u", "fed11xyz.."],
+    ["modules", "lightning,wallet,mint"],
+    ["n", "signet"]
+  ]
+}
+```
+
+* `content` is an optional `metadata`-like stringified JSON object, as described in NIP-01. This content is useful when the pubkey creating the `kind:38173` is not a normal user. If `content` is empty, the `kind:0` of the pubkey should be used to display mint information (e.g. name, picture, web, LUD16, etc.)
+
+## Example
+
+### User A recommends some mints
+User A might be a user of a cashu mint. Using a client, user A publishes an event recommending the cashu mint they use.
+
+```json
+{
+  "kind": 38000,
+  "tags": [
+    ["u", "fed11abc..", "fedimint"],
+    ["u", "https://cashu.example.com", "cashu"],
+    ["a", "38173:fedimint-pubkey:<d-identifier>", "wss://relay1", "fedimint"],
+    ["a", "38172:cashu-mint-pubkey:<d-identifier>", "wss://relay2", "cashu"]
+  ],
+  ...
+}
+```
+
+### User B finds a mint
+User B wants to use an ecash wallet, they need to find a mint.
+
+User B's wallet client queries for `kind:38000` events, looking for recommendations for ecash mints.
+
+```json
+["REQ", <id>, [{ "kinds": [38000], "authors": [<user>, <users-contact-list>], "#k": ["38173"] }]]
+```
+
+User B, who follows User A, sees that `kind:38000` event and tries to connect to the corresponding mints.
+
+### Alternative query bypassing `kind:38000`
+Alternatively, users might choose to query directly for `kind:38173` for an event kind. Clients SHOULD be careful doing this and use spam-prevention mechanisms or querying high-quality restricted relays to avoid directing users to malicious handlers.
+
+```json
+["REQ", <id>, [{ "kinds": [38173], "authors": [...] }]]

+Polls
+-----
+
+`draft` `optional`
+
+This NIP defines the event scheme that describe Polls on nostr.
+
+## Events
+
+### Poll Event
+
+The poll event is defined as a `kind:1068` event.
+
+- **content** key holds the label for the poll.
+
+Major tags in the poll event are:
+
+- **option**: The option tags contain an OptionId(any alphanumeric) field, followed by an option label field.
+- **relay**: One or multiple tags that the poll is expecting respondents to respond on.
+- **polltype**: can be "singlechoice" or "multiplechoice". Polls that do not have a polltype should be considered a "singlechoice" poll.
+- **endsAt**: signifying at which unix timestamp the poll is meant to end.
+
+Example Event
+
+```json
+{
+  "content": "Pineapple on pizza",
+  "created_at": 1719888496,
+  "id": "9d1b6b9562e66f2ecf35eb0a3c2decc736c47fddb13d6fb8f87185a153ea3634",
+  "kind": 1068,
+  "pubkey": "dee45a23c4f1d93f3a2043650c5081e4ac14a778e0acbef03de3768e4f81ac7b",

+  "tags": [
+    ["option", "qj518h583", "Yay"],
+    ["option", "gga6cdnqj", "Nay"],
+    ["relay", "<relay url1>"],
+    ["relay", "<relay url2>"],
+    ["polltype", "singlechoice"],
+    ["endsAt", "<unix timestamp in seconds>"]
+  ]
+}
+```
+
+### Responses
+
+The response event is a `kind:1018` event. It contains an e tag with the poll event it is referencing, followed by one or more response tags.
+
+- **response** : The tag contains "response" as it's first positional argument followed by the option Id selected.
+
+The responses are meant to be published to the relays specified in the poll event.
+
+Example Response Event
+
+```json
+{
+  "content": "",
+  "created_at": 1720097117,
+  "id": "60a005e32e9596c3f544a841a9bc4e46d3020ca3650d6a739c95c1568e33f6d8",
+  "kind": 1018,
+  "pubkey": "1bc70a0148b3f316da33fe7e89f23e3e71ac4ff998027ec712b905cd24f6a411",
+  "sig": "30071a633c65db8f3a075c7a8de757fbd8ce65e3607f4ba287fe6d7fbf839a380f94ff4e826fbba593f6faaa13683b7ea9114ade140720ecf4927010ebf3e44f",
+  "tags": [
+    ["e", "1fc80cf813f1af33d5a435862b7ef7fb96b47e68a48f1abcadf8081f5a545550"],
+    ["response", "gga6cdnqj"],
+    ["response", "m3agjsdq1"]
+  ]
+}
+```
+
+### Poll Types
+
+The polltype setting dictates how multiple response tags are handled in the `kind:1018` event.
+
+- **polltype: singlechoice**: The first response tag is to be considered the actual response.
+- **polltype: multiplechoice**: The first response tag pointing to each id is considered the actual response, without considering the order of the response tags.
+
+### Counting Results
+
+Results can be queried by fetching `kind:1018` events from the relays specified in the poll.
+The results displayed should only be 1 vote event per pubkey.
+In case of multiple events for a pubkey, the event with the largest timestamp within the poll limits should be considered.
+
+Example for querying polls.
+
+```ts
+const fetchVoteEvents = (filterPubkeys: string[]) => {
+  let resultFilter: Filter = {
+    "#e": [pollEvent.id],
+    kinds: [1018],
+  };
+  if (filterPubkeys?.length) {
+    resultFilter.authors = filterPubkeys;
+  }
+  if (pollExpiration) {
+    resultFilter.until = Number(pollExpiration);
+  }
+  pool.subscribeMany(relays, [resultFilter], {
+    onevent: handleResultEvent,
+  });
+};
+```
+
+Example for maintaining OneVotePerPubkey
+
+```ts
+const oneVotePerPubkey = (events: Event[]) => {
+  const eventMap = new Map<string, Event>();
+
+  events.forEach((event) => {
+    if (
+      !eventMap.has(event.pubkey) ||
+      event.created_at > eventMap.get(event.pubkey)!.created_at
+    ) {
+      eventMap.set(event.pubkey, event);
+    }
+  });
+
+  return Array.from(eventMap.values());
+};
+```
+
+### Relays
+
+It is advisable for poll authors to use relays that do not allow backdated events and do not honor kind:5 (delete) requests for vote events in order to maintain the integrity of poll results after the poll has ended.
+
+### Curation
+
+The clients may configure fetching results by specific people. This can be achieved by creating `kind:30000` follow sets, and fetching results only from the follow set.
+Clients can also employ other curation algorithms, like Proof Of Work and Web of Trust scores for result curations.

+
+HTTP File Storage Integration
+-----------------------------
+
+`draft` `optional`
+
+## Introduction
+
+This NIP defines a REST API for HTTP file storage servers intended to be used in conjunction with the nostr network.
+The API will enable nostr users to upload files and later reference them by url on nostr notes.
+
+The spec DOES NOT use regular nostr events through websockets for
+storing, requesting nor retrieving data because, for simplicity, the server
+will not have to learn anything about nostr relays.
+
+## Server Adaptation
+
+File storage servers wishing to be accessible by nostr users should opt-in by making available an https route at `/.well-known/nostr/nip96.json` with `api_url`:
+
+```jsonc
+{
+  // Required
+  // File upload and deletion are served from this url
+  // Also downloads if "download_url" field is absent or empty string
+  "api_url": "https://your-file-server.example/custom-api-path",
+  // Optional
+  // If absent, downloads are served from the api_url
+  "download_url": "https://a-cdn.example/a-path",
+  // Optional
+  // Note: This field is not meant to be set by HTTP Servers.
+  // Use this if you are a nostr relay using your /.well-known/nostr/nip96.json
+  // just to redirect to someone else's http file storage server's /.well-known/nostr/nip96.json
+  // In this case, "api_url" field must be an empty string
+  "delegated_to_url": "https://your-file-server.example",
+  // Optional
+  "supported_nips": [60],
+  // Optional
+  "tos_url": "https://your-file-server.example/terms-of-service",
+  // Optional
+  "content_types": ["image/jpeg", "video/webm", "audio/*"],
+  // Optional
+  "plans": {
+    // "free" is the only standardized plan key and
+    // clients may use its presence to learn if server offers free storage
+    "free": {
+      "name": "Free Tier",
+      // Default is true
+      // All plans MUST support NIP-98 uploads
+      // but some plans may also allow uploads without it
+      "is_nip98_required": true,
+      "url": "https://...", // plan's landing page if there is one
+      "max_byte_size": 10485760,
+      // Range in days / 0 for no expiration
+      // [7, 0] means it may vary from 7 days to unlimited persistence,
+      // [0, 0] means it has no expiration
+      // early expiration may be due to low traffic or any other factor
+      "file_expiration": [14, 90],
+      "media_transformations": {
+        "image": [
+          "resizing"
+        ]
+      }
+    }
+  }
+}
+```
+
+### Relay Hints
+
+Note: This section is not meant to be used by HTTP Servers.
+
+A nostr relay MAY redirect to someone else's HTTP file storage server by
+adding a `/.well-known/nostr/nip96.json` with "delegated_to_url" field
+pointing to the url where the server hosts its own
+`/.well-known/nostr/nip96.json`. In this case, the "api_url" field must
+be an empty string and all other fields must be absent.
+
+If the nostr relay is also an HTTP file storage server,
+it must use the "api_url" field instead.
+
+### List of Supporting File Storage Servers
+
+See https://github.com/aljazceru/awesome-nostr#nip-96-file-storage-servers.
+
+## Auth
+
+When indicated, `clients` must add an [NIP-98](98.md) `Authorization` header (**optionally** with the encoded `payload` tag set to the base64-encoded 256-bit SHA-256 hash of the file - not the hash of the whole request body).
+
+## Upload
+
+`POST $api_url` as `multipart/form-data`.
+
+**AUTH required**
+
+List of form fields:
+
+- `file`: **REQUIRED** the file to upload
+- `caption`: **RECOMMENDED** loose description;
+- `expiration`: UNIX timestamp in seconds. Empty string if file should be stored forever. The server isn't required to honor this.
+- `size`: File byte size. This is just a value the server can use to reject early if the file size exceeds the server limits.
+- `alt`: **RECOMMENDED** strict description text for visibility-impaired users.
+- `media_type`: "avatar" or "banner". Informs the server if the file will be used as an avatar or banner. If absent, the server will interpret it as a normal upload, without special treatment.
+- `content_type`: mime type such as "image/jpeg". This is just a value the server can use to reject early if the mime type isn't supported.
+- `no_transform`: "true" asks server not to transform the file and serve the uploaded file as is, may be rejected.
+
+Others custom form data fields may be used depending on specific `server` support.
+The `server` isn't required to store any metadata sent by `clients`.
+
+The `filename` embedded in the file may not be honored by the `server`, which could internally store just the SHA-256 hash value as the file name, ignoring extra metadata.
+The hash is enough to uniquely identify a file, that's why it will be used on the `download` and `delete` routes.
+
+The `server` MUST link the user's `pubkey` string as the owner of the file so to later allow them to delete the file.
+
+`no_transform` can be used to replicate a file to multiple servers for redundancy, clients can use the [server list](#selecting-a-server) to find alternative servers which might contain the same file. When uploading a file and requesting `no_transform` clients should check that the hash matches in the response in order to detect if the file was modified.
+
+### Response codes
+
+- `200 OK`: File upload exists, but is successful (Existing hash)
+- `201 Created`: File upload successful (New hash)
+- `202 Accepted`: File upload is awaiting processing, see [Delayed Processing](#delayed-processing) section
+- `413 Payload Too Large`: File size exceeds limit
+- `400 Bad Request`: Form data is invalid or not supported.
+- `403 Forbidden`: User is not allowed to upload or the uploaded file hash didnt match the hash included in the `Authorization` header `payload` tag.
+- `402 Payment Required`: Payment is required by the server, **this flow is undefined**.
+
+The upload response is a json object as follows:
+
+```jsonc
+{
+  // "success" if successful or "error" if not
+  "status": "success",
+  // Free text success, failure or info message
+  "message": "Upload successful.",
+  // Optional. See "Delayed Processing" section
+  "processing_url": "...",
+  // This uses the NIP-94 event format but DO NOT need
+  // to fill some fields like "id", "pubkey", "created_at" and "sig"
+  //
+  // This holds the download url ("url"),
+  // the ORIGINAL file hash before server transformations ("ox")
+  // and, optionally, all file metadata the server wants to make available
+  //
+  // nip94_event field is absent if unsuccessful upload
+  "nip94_event": {
+    // Required tags: "url" and "ox"
+    "tags": [
+      // Can be same from /.well-known/nostr/nip96.json's "download_url" field
+      // (or "api_url" field if "download_url" is absent or empty) with appended
+      // original file hash.
+      //
+      // Note we appended .png file extension to the `ox` value
+      // (it is optional but extremely recommended to add the extension as it will help nostr clients
+      // with detecting the file type by using regular expression)
+      //
+      // Could also be any url to download the file
+      // (using or not using the /.well-known/nostr/nip96.json's "download_url" prefix),
+      // for load balancing purposes for example.
+      ["url", "https://your-file-server.example/custom-api-path/719171db19525d9d08dd69cb716a18158a249b7b3b3ec4bbdec5698dca104b7b.png"],

+      ["ox", "719171db19525d9d08dd69cb716a18158a249b7b3b3ec4bbdec5698dca104b7b"],

+      // The server can but does not need to store this value.
+      ["x", "543244319525d9d08dd69cb716a18158a249b7b3b3ec4bbde5435543acb34443"],

+      // Optional. Recommended for helping clients to reserve an adequate UI space to show the file before downloading it.
+      ["dim", "800x600"]
+      // ... other optional NIP-94 tags
+    ],
+    "content": ""
+  },
+  // ... other custom fields (please consider adding them to this NIP or to NIP-94 tags)
+}
+```
+
+Note that if the server didn't apply any transformation to the received file, both `nip94_event.tags.*.ox` and `nip94_event.tags.*.x` fields will have the same value. The server MUST link the saved file to the SHA-256 hash of the **original** file before any server transformations (the `nip94_event.tags.*.ox` tag value). The **original** file's SHA-256 hash will be used to identify the saved file when downloading or deleting it.
+
+`clients` may upload the same file to one or many `servers`.
+After successful upload, the `client` may optionally generate and send to any set of nostr `relays` a [NIP-94](94.md) event by including the missing fields.
+
+Alternatively, instead of using NIP-94, the `client` can share or embed on a nostr note just the above url.
+
+`clients` may also use the tags from the `nip94_event` to construct an `imeta` tag
+
+### Delayed Processing
+
+Sometimes the server may want to place the uploaded file in a processing queue for deferred file processing.
+
+In that case, the server MUST serve the original file while the processing isn't done, then swap the original file for the processed one when the processing is over. The upload response is the same as usual but some optional metadata like `nip94_event.tags.*.x` and `nip94_event.tags.*.size` won't be available.
+
+The expected resulting metadata that is known in advance should be returned on the response.
+For example, if the file processing would change a file from "jpg" to "webp",
+use ".webp" extension on the `nip94_event.tags.*.url` field value and set "image/webp" to the `nip94_event.tags.*.m` field.
+If some metadata are unknown before processing ends, omit them from the response.
+
+The upload response MAY include a `processing_url` field informing a temporary url that may be used by clients to check if
+the file processing is done.
+
+If the processing isn't done, the server should reply at the `processing_url` url with **200 OK** and the following JSON:
+
+```jsonc
+{
+  // It should be "processing". If "error" it would mean the processing failed.
+  "status": "processing",
+  "message": "Processing. Please check again later for updated status.",
+  "percentage": 15 // Processing percentage. An integer between 0 and 100.
+}
+```
+
+When the processing is over, the server replies at the `processing_url` url with **201 Created** status and a regular successful JSON response already mentioned before (now **without** a `processing_url` field), possibly including optional metadata at `nip94_event.tags.*` fields
+that weren't available before processing.
+
+### File compression
+
+File compression and other transformations like metadata stripping can be applied by the server.
+However, for all file actions, such as download and deletion, the **original** file SHA-256 hash is what identifies the file in the url string.
+
+## Download
+
+`GET $api_url/<sha256-hash>(.ext)`
+
+The primary file download url informed at the upload's response field `nip94_event.tags.*.url`
+can be that or not (it can be any non-standard url the server wants).
+If not, the server still MUST also respond to downloads at the standard url
+mentioned on the previous paragraph, to make it possible for a client
+to try downloading a file on any NIP-96 compatible server by knowing just the SHA-256 file hash.
+
+Note that the "\<sha256-hash\>" part is from the **original** file, **not** from the **transformed** file if the uploaded file went through any server transformation.
+
+Supporting ".ext", meaning "file extension", is required for `servers`. It is optional, although recommended, for `clients` to append it to the path.
+When present it may be used by `servers` to know which `Content-Type` header to send (e.g.: "Content-Type": "image/png" for ".png" extension).
+The file extension may be absent because the hash is the only needed string to uniquely identify a file.
+
+Example: `$api_url/719171db19525d9d08dd69cb716a18158a249b7b3b3ec4bbdec5698dca104b7b.png`
+
+### Media Transformations
+
+`servers` may respond to some media transformation query parameters and ignore those they don't support by serving
+the original media file without transformations.
+
+#### Image Transformations
+
+##### Resizing
+
+Upon upload, `servers` may create resized image variants, such as thumbnails, respecting the original aspect ratio.
+`clients` may use the `w` query parameter to request an image version with the desired pixel width.
+`servers` can then serve the variant with the closest width to the parameter value
+or an image variant generated on the fly.
+
+Example: `$api_url/<sha256-hash>.png?w=32`
+
+## Deletion
+
+`DELETE $api_url/<sha256-hash>(.ext)`
+
+**AUTH required**
+
+Note that the `/<sha256-hash>` part is from the **original** file, **not** from the **transformed** file if the uploaded file went through any server transformation.
+
+The extension is optional as the file hash is the only needed file identification.
+
+The `server` should reject deletes from users other than the original uploader with the appropriate http response code (403 Forbidden).

+It should be noted that more than one user may have uploaded the same file (with the same hash). In this case, a delete must not really delete the file but just remove the user's `pubkey` from the file owners list (considering the server keeps just one copy of the same file, because multiple uploads of the same file results
+in the same file hash).

+Voice Messages
+-----------
+
+**Status:** Draft
+
+This NIP defines new events `kind: 1222` for root messages and `kind: 1244` for reply messages to be used for short voice messages, typically up to 60 seconds in length.
+
+## Specification
+
+### Event Kind `1222` and Kind `1244`
+
+The `kind: 1222` event is defined as follows:
+
+-   `content`: MUST be a URL pointing directly to an audio file.
+    -   The audio file SHOULD be in `audio/mp4` (.m4a) format using AAC or Opus encoding. Clients MAY support other common audio formats like `audio/ogg`, `audio/webm`, or `audio/mpeg` (mp3), but `audio/mp4` is recommended for broad compatibility and efficiency.
+    -   The audio duration SHOULD be no longer than 60 seconds. Clients publishing `kind: 1222` events SHOULD enforce this limit or provide a clear warning to the user if exceeded.
+-   `tags`:
+    -   Tags MAY be included as per other NIPs (e.g., `t` for hashtags, `g` for geohash, etc.).
+
+  The `kind: 1244` event is defined as follows:
+  
+-    To be used for replies, `kind: 1244` events MUST follow the structure of `NIP-22`.
+-   `content`: MUST be a URL pointing directly to an audio file.
+    -   The audio file SHOULD be in `audio/mp4` (.m4a) format using AAC or Opus encoding. Clients MAY support other common audio formats like `audio/ogg`, `audio/webm`, or `audio/mpeg` (mp3), but `audio/mp4` is recommended for broad compatibility and efficiency.
+    -   The audio duration SHOULD be no longer than 60 seconds. Clients publishing `kind: 1222` events SHOULD enforce this limit or provide a clear warning to the user if exceeded.
+-   `tags`:
+    -   Tags MAY be included as per other NIPs (e.g., `t` for hashtags, `g` for geohash, etc.).
+
+
+## Visual representation with `imeta` (NIP-92) tag (optional)
+
+The following imeta (NIP-92) tags MAY be included so clients can render a visual preview without having to download the audio file first:
+
+- `waveform`: amplitude values over time, space separated full integers, less than 100 values should be enough to render a nice visual
+- `duration`: audio length in seconds

+Web Bookmarking
+---------------
+
+`draft` `optional`
+
+This NIP defines `kind:39701` (an _addressable event_) for a URI as a web bookmark which uses the HTTP (Hypertext transfer protocol) scheme.
+These web bookmark events are _addressable_ and deletable per [NIP-09](09.md).
+
+### Editability
+
+Web bookmarks are meant to be editable, so they should include a `d` tag with an identifier for the bookmark. Clients should take care to only publish and read these events from relays that implement that. If they don't do that they should also take care to hide old versions of the same bookmark they may receive.
+
+### Format
+
+The format uses an _addressable event_ of `kind:39701`.
+
+The `.content` of these events should be a detailed description of the web bookmark. It is required but can be an empty string.
+
+The `d` tag is required.
+
+In this way web bookmarks events can be queried by the `d` tag by clients, which is just their URL without the scheme, which is always and everywhere assumed to be `https://` or `http://`.
+
+The querystring and the hash must be removed entirely, unless their requirement is explicitly stated either by the user or by some hardcoded list of URLs that rely on querystrings for basic routing provided by the client.
+
+### Metadata
+
+For the date of the last update the `.created_at` field should be used. For "tags"/"hashtags" (i.e. topics about which the event might be of relevance) the `t` tag should be used.
+
+Other metadata fields can be added as tags to the event as necessary.
+
+* `"published_at"`, for the timestamp in unix seconds (stringified) of the first time the bookmark was published
+* `"title"`, title about bookmark and can be used as a attribute for the HTML link element

+
+Blossom media
+-------------
+
+`draft` `optional`
+
+This NIP specifies how Nostr clients can use [Blossom][] for handling media.
+
+Blossom is a set of standards (called BUDs) for dealing with servers that store files addressable by their SHA-256 sums. Nostr clients may make use of all the BUDs for allowing users to upload files, manage their own files and so on, but most importantly Nostr clients SHOULD make use of [BUD-03][] to fetch `kind:10063` lists of servers for each user:
+
+```json
+{
+  "id": "e4bee088334cb5d38cff1616e964369c37b6081be997962ab289d6c671975d71",
+  "pubkey": "781208004e09102d7da3b7345e64fd193cd1bc3fce8fdae6008d77f9cabcd036",
+  "content": "",
+  "kind": 10063,
+  "created_at": 1708774162,
+  "tags": [
+    ["server", "https://blossom.self.hosted"],
+    ["server", "https://cdn.blossom.cloud"]
+  ],
+  "sig": "cc5efa74f59e80622c77cacf4dd62076bcb7581b45e9acff471e7963a1f4d8b3406adab5ee1ac9673487480e57d20e523428e60ffcc7e7a904ac882cfccfc653"
+}
+```
+
+Whenever a Nostr client finds a URL in an event published by a given user and that URL ends a 64-character hex string (with or without an ending file extension) and that URL is not available anymore, that means that string is likely a representation of a sha256 and that the user may have a `kind:10063` list of Blossom servers published.
+
+Given that, the client SHOULD look into the `kind:10063` list for other Blossom servers and lookup for the same 64-character hex string in them, by just using the hex string as a path (optionally with the file extension at the end), producing a URL like `https://blossom.self.hosted/<hex-string>.png`.
+
+When downloading such files Nostr clients SHOULD verify that the sha256-hash of its contents matches the 64-character hex string.
+
+More information can be found at [BUD-03][].
+
+### More complex interactions
+
+Clients may use other facilities exposed by Blossom servers (for example, for checking if a file exists in a Blossom server, instead of actually downloading it) which are better documented in the [BUDs][Blossom].

+Code Snippets
+-------------
+
+`draft` `optional`
+
+## Abstract
+
+This NIP defines a new event kind for sharing and storing code snippets. Unlike regular text notes (`kind:1`), code snippets have specialized metadata like language, extension, and other code-specific attributes that enhance discoverability, syntax highlighting, and improved user experience.
+
+## Event Kind
+
+This NIP defines `kind:1337` as a code snippet event.
+
+The `.content` field contains the actual code snippet text.
+
+## Optional Tags
+
+- `l` - Programming language name (lowercase). Examples: "javascript", "python", "rust"
+- `name` - Name of the code snippet, commonly a filename. Examples: "hello-world.js", "quick-sort.py"
+- `extension` - File extension (without the dot). Examples: "js", "py", "rs"
+- `description` - Brief description of what the code does
+- `runtime` - Runtime or environment specification (e.g., "node v18.15.0", "python 3.11")
+- `license` - License under which the code is shared (e.g., "MIT", "GPL-3.0", "Apache-2.0")
+- `dep` - Dependency required for the code to run (can be repeated)
+- `repo` - Reference to a repository where this code originates
+
+## Format
+
+```json
+{
+  "id": "<32-bytes lowercase hex-encoded SHA-256 of the the serialized event data>",
+  "pubkey": "<32-bytes lowercase hex-encoded public key of the event creator>",
+  "created_at": <Unix timestamp in seconds>,
+  "kind": 1337,
+  "content": "function helloWorld() {\n  console.log('Hello, Nostr!');\n}\n\nhelloWorld();",
+  "tags": [
+    ["l", "javascript"],
+    ["extension", "js"],
+    ["name", "hello-world.js"],
+    ["description", "A basic JavaScript function that prints 'Hello, Nostr!' to the console"],
+    ["runtime", "node v18.15.0"],
+    ["license", "MIT"],
+    ["repo", "https://github.com/nostr-protocol/nostr"]
+  ],
+  "sig": "<64-bytes signature of the id>"
+}
+```
+
+## Client Behavior
+
+Clients that support this NIP SHOULD:
+
+1. Display code snippets with proper syntax highlighting based on the language.
+2. Allow copying the full code snippet with a single action.
+3. Render the code with appropriate formatting, preserving whitespace and indentation.
+4. Display the language and extension prominently.
+5. Provide "run" functionality for supported languages when possible.
+6. Display the description (if available) as part of the snippet presentation.
+
+Clients MAY provide additional functionality such as:
+
+1. Code editing capabilities
+2. Forking/modifying snippets
+3. Creating executable environments based on the runtime/dependencies
+4. Downloading the snippet as a file using the provided extension
+5. Sharing the snippet with attribution

+
+A chat message is a `kind 9` event.
+
+```json
+{
+  "kind": 9,
+  "content": "GM",
+  "tags": []
+}
+```
+
+A reply to a `kind 9` is an additional `kind 9` which quotes the parent using a `q` tag.
+
+```json
+{
+  "kind": 9,
+  "content": "nostr:nevent1...\nyes",
+  "tags": [
+    ["q", <event-id>, <relay-url>, <pubkey>]

+1. They should be fully implemented in at least two clients and one relay -- when applicable.
 2. They should make sense.
 3. They should be optional and backwards-compatible: care must be taken such that clients and relays that choose to not implement them do not stop working when interacting with the ones that choose to.
 4. There should be no more than one way of doing the same thing.

 These two ways of standardizing things are supported by this repository. Although the second is preferred, an effort will be made to codify standards emerged outside this repository into NIPs that can be later referenced and easily understood and implemented by others -- but obviously as in any human system discretion may be applied when standards are considered harmful.
