 ### 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, especifies the `kind:1` text note for social media applications.

+
+The negotiation works as follows.
+
+1. The **wallet service** includes an `encryption` tag in the `info` event. This tag contains a space-separated list of encryption schemes that the **wallet service** supports (eg. `nip44_v2 nip04`)
+2. The **client application** includes an `encryption` tag in each request event. This tag contains the encryption scheme which should be used for the request. The **client application** should always prefer nip44 if supported by the **wallet service**.
+
+### Info event
+
+First, the **wallet service** adds an `encryption` tag to its `info` event containing a space-separated list of encryption schemes it supports. For example,
+if a wallet service supports nip44, but also allows backwards-compatibility to nip04 client applications, its `encryption` tag in the `info` event might look something like:
+
+```jsonc
+{
+    "kind": 13194,
+    "tags": [
+        ["encryption", "nip44_v2 nip04"],
+        // ...
+    ],
+    "content": "pay_invoice get_balance make_invoice lookup_invoice list_transactions get_info",
+    // ...
+}
+```
+
+When a **client application** establishes a connection, it should read the info event and look for the `encryption` tag.
+
+**Absence of this tag implies that the wallet only supports nip04.**
+
+If the `encryption` tag is present, the **client application** will choose optimal encryption supported by both itself, and the **wallet service**, which should always be nip44 if possible.
+
+### Request events
+
+When a **client application** sends a request event, it should include a `encryption` tag with the encryption scheme it is using. The scheme MUST be supported by the **wallet service** as indicated by the info event.
+For example, if the client application supports nip44, the request event might look like:
+
+```jsonc
+{
+    "kind": 23194,
+    "tags": [
+        ["encryption", "nip44_v2"],
+        // ...
+    ],
+    // ...
+}
+```
+
+If the **wallet service** does not support the specified encryption scheme, it will return an `UNSUPPORTED_ENCRYPTION` error. Absence of the `encryption` tag indicates use of nip04 for encryption.
+
+### Notification events
+
+As described above in the [Notifications](#notifications) section, if a **wallet service** supports both nip04 and nip44, it should publish two notification events for each notification - kind 23196 encrypted with NIP-04, and kind 23197 encrypted with NIP-44. If the **wallet service** only supports nip44, it should only publish kind 23197 events.
+
+The **client** should check the `encryption` tag in the `info` event to determine which encryption schemes the **wallet service** supports, and listen to the appropriate notification event.

 ## 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.

+## Collaborative Calendar Event Requests
+
+Calendar events can include an `a` tag referencing a calendar (kind 31924) to request addition to that calendar. When a calendar event includes such a reference, clients should interpret this as a request to add the event to the referenced calendar by referencing it with an `a` tag.

+## 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
+    ["service", "<url>"],                      // Required: URL to access the room
+    ["endpoint", "<url>"],                     // Optional: API endpoint for status/info
+    ["t", "<hashtag>"],                        // Optional: Multiple hashtags allowed
+    ["p", "<pubkey>", "<url>", "<role>", "<proof>"],  // Required: At least one provider
+    ["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
+    ["starts", "<unix timestamp>"],            // Required: Start time
+    ["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

+## Room Presence
+
+New `kind: 10312` provides an event which signals presence of a listener. 
+
+The presence event SHOULD be updated at regular intervals and clients SHOULD filter presence events older than 
+a given time window.
+
+**This kind `10312` is a regular replaceable event, as such presence can only be indicated in one room at a time.**
+
+```json
+{

-### 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.
+Tags with more than one value should be repeated, rather than putting all values in a single tag, for example `[["t", "cats"], ["t", "dogs"]]`, rather than `[["t", "cats", "dogs"]]`.
 
-### Purpose 
-Discovery of relays over nostr. 
+Example:
 
-### 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.

-  [ "R", "auth" ],

+## Relay Monitor Announcements
 
-### 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.
+Kind `10166` relay monitor announcements advertise the author's intent to publish `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.
+Tags include:
 
-### Schema
+- `frequency` - The frequency in seconds at which the monitor publishes events.
+- `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.
+- `c` - a lowercase string describing the checks conducted by a monitor. Examples include `open`, `read`, `write`, `auth`, `nip11`, `dns`, and `geo`.

-- `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. 
+Example:
 
-  ```json
-  [ "frequency", "3600" ]

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_.

-## 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.

 # Posting to a community
 
-Any Nostr event can be posted to a community. Clients MUST add one or more community `a` tags, each with a recommended relay.
+[NIP-22](NIP-22) kind 1111 events SHOULD be used for text notes posted to a community, with the `A` tag always scoped to the community definition.
+
+## Top-level posts
+
+For top-level posts, the uppercase and lowercase NIP-22 tags should both refer to the community definition itself.
 
 ```jsonc
 {
-  "kind": 1,
+  "kind": 1111,

+
+## Backwards compatibility note
+
+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.

+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

+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": [...] }]]

+  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

+
+Out-of-line Styles
+------------------
+
+`draft` `optional`
+
+Out-of-line styles are text formatting data not inlined in the
+event's `.content` field but placed into `st` (style) tags.
+
+## Motivation
+
+With markup languages such as Markdown, AsciiDoc and HTML, clients
+would be required to add an ever growing number of parsers to
+support textual event kinds.
+
+If keeping `.content` field limited to plaintext,
+clients can show text with no extraneous markup delimiter chars
+that could impact readability.
+
+When a client chooses to support formatting, it can
+add parser code just once and it will work for all textual
+events. If the parser in incomplete, there is not much
+problem because the raw text inside `.content` is perfectly readable.
+
+## Writing Text
+
+A client should offer text formatting in any markup language,
+for example, WYSIWYG powered by HTML, or Markdown editor.
+However, before saving the event it should transform the resulting
+text into an unformatted `.content` with added style tags.
+
+## Style Tags
+
+A style tag delimits an inclusive character range
+and specifies a style to be applied using the following syntax:
+`["st", "<starting-character-index>:<ending-character-index>", "<style-name>"]`
+
+### Style Names
+
+- `h<1-to-9>`: Header (h1) or subheader
+- `strong`: Strong importance; should use heavier weight font.
+- `em`: Emphasis; should use italic type.
+- `small`: Small print, like copyright and legal text. Use smaller font-size.
+- `strike`: Stricken text. Should remove leading and trailing `-`.
+- `del`: Deleted text, such as after a git commit. Should remove leading `-` and spaces.
+- `ins`: Inserted text, such as after a git commit. Should remove leading `+` and spaces.
+- `sub`: Text should be displayed as subscript.
+- `sup`: Text should be displayed as superscript.
+- `link`: Alternative text to be displayed in place of a URL as a link. The alternative text can't itself be a URL.
+E.g.: `["st", "0:35", "link", "my previous post"]`
+- `mark` Text should be highlighted with a different background color.
+- `quote`: Quoted text. Should remove leading and trailing `"`.
+- `dsv` or `dsv:<delimiter-char-sequence>`: Delimiter separated value. The default delimiter is `|`.
+Another delimiter that doesn't clash with the actual values may be choosed, e.g.: `dsv:#-#`. Values should be trimmed.
+- `code` or `code:<lowercase-language-name-without-space>)`: Displays code, optionally in some language.
+
+Styles may be combined, for instance, a `dsv`'s header may have its char range set to `h1`.
+
+## Example
+
+```js
+{
+  "tags": [
+    ["st", "0:7", "h1"],
+    ["st", "10:29", "h2"],
+    ["st", "51:51", "h1"],
+    ["st", "10:71", "dsv"]
+  ],
+  "content": "My Title
+
+  |    B    |    C
+D | Item B1 | Item C1
+E | Item B2 | Item C2
+
+  • Bullet points don't need style tags
+  • I simply used spaces to ident these
+  1) Here too
+  1.1) Example"
+  // other fields
+}
+```
