-### Tags
-
-Each tag is an array of strings of arbitrary size, with some conventions around them. Take a look at the example below:
-
-```json
-{
-  ...,
-  "tags": [
-    ["e", "5c83da77af1dec6d7289834998ad7aafbd9e2191396d75ec3cc27f5a77226f36", "wss://nostr.example.com"],

-    ["alt", "reply"],
-    ...
-  ],
-  ...
-}
-```
-
-The first element of the tag array is referred to as the tag _name_ or _key_ and the second as the tag _value_. So we can safely say that the event above has an `e` tag set to `"5c83da77af1dec6d7289834998ad7aafbd9e2191396d75ec3cc27f5a77226f36"`, an `alt` tag set to `"reply"` and so on. All elements after the second do not have a conventional name.
-
-This NIP defines 3 standard tags that can be used across all event kinds with the same meaning. They are as follows:
-
-- The `e` tag, used to refer to an event: `["e", <32-bytes lowercase hex of the id of another event>, <recommended relay URL, optional>]`
-- The `p` tag, used to refer to another user: `["p", <32-bytes lowercase hex of a pubkey>, <recommended relay URL, optional>]`
-- The `a` tag, used to refer to a (maybe parameterized) replaceable event
-    - for a parameterized replaceable event: `["a", <kind integer>:<32-bytes lowercase hex of a pubkey>:<d tag value>, <recommended relay URL, optional>]`
-    - for a non-parameterized replaceable event: `["a", <kind integer>:<32-bytes lowercase hex of a pubkey>:, <recommended relay URL, optional>]`
-
-As a convention, all single-letter (only english alphabet letters: a-z, A-Z) key tags are expected to be indexed by relays, such that it is possible, for example, to query or subscribe to events that reference the event `"5c83da77af1dec6d7289834998ad7aafbd9e2191396d75ec3cc27f5a77226f36"` by using the `{"#e": "5c83da77af1dec6d7289834998ad7aafbd9e2191396d75ec3cc27f5a77226f36"}` filter.
-
-### 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:
-
-- `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.
-
-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 `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.
-
-When answering to `REQ` messages for replaceable events such as `{"kinds":[0],"authors":[<hex-key>]}`, even if the relay has more than one version stored, it SHOULD return just the latest one.
-
-These are just conventions and relay implementations may differ.
-
 ## Communication between clients and relays
 
-Relays expose a websocket endpoint to which clients can connect. Clients SHOULD open a single websocket connection to each relay and use it for all their subscriptions. Relays MAY limit number of connections from specific IP/client/etc.
-
-### Meaning of WebSocket status codes
-
-- When a websocket is closed by the relay with a status code `4000` that means the client shouldn't try to connect again.

For scalar event attributes such as `authors` and `kind`, the attribute from the event must be contained in the filter list.

-The `ids`, `authors`, `#e` and `#p` filter lists MUST contain exact 64-character lowercase hex values.
+The `ids` and `authors` lists contain lowercase hexadecimal strings, which may either be an exact 64-character match, or a prefix of the event value.  A prefix match is when the filter string is an exact string prefix of the event value.  The use of prefixes allows for more compact filters where a large number of values are queried, and can provide some privacy for clients that may not want to disclose the exact authors or events they are searching for.
 
 The `since` and `until` properties can be used to specify the time range of events returned in the subscription. If a filter includes the `since` property, events with `created_at` greater than or equal to `since` are considered to match the filter. The `until` property is similar except that `created_at` must be less than or equal to `until`. In short, an event matches a filter if `since <= created_at <= until` holds.

-  * `["OK", <event_id>, <true|false>, <message>]`, used to indicate acceptance or denial of an `EVENT` message.

   * `["NOTICE", <message>]`, used to send human-readable error messages or other things to clients.
 
 This NIP defines no rules for how `NOTICE` messages should be sent or treated.
 
-- `EVENT` messages MUST be sent only with a subscription ID related to a subscription previously initiated by the client (using the `REQ` message above).
-- `OK` messages MUST be sent in response to `EVENT` messages received from clients, they must have the 3rd parameter set to `true` when an event has been accepted by the relay, `false` otherwise. The 4th parameter MAY be empty when the 3rd is `true`, otherwise it MUST be a string containing a machine-readable single-word prefix followed by a `:` and then a human-readable message. The standardized machine-readable prefixes are: `duplicate`, `pow`, `blocked`, `rate-limited`, `invalid`, and `error` for when none of that fits. Some examples:

-  * `["OK", "b1a649ebe8...", false, "blocked: please register your pubkey at https://my-expensive-relay.example.com"]`
-  * `["OK", "b1a649ebe8...", false, "rate-limited: slow down there chief"]`
-  * `["OK", "b1a649ebe8...", false, "invalid: event creation date is too far off from the current time. Is your system clock in sync?"]`
-  * `["OK", "b1a649ebe8...", false, "pow: difficulty 26 is less than 30"]`
-  * `["OK", "b1a649ebe8...", false, "error: could not connect to the database"]`
+## Basic Event Kinds
+
+  - `0`: `set_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 past `set_metadata` 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.
+  - `2`: `recommend_server`: the `content` is set to the URL (e.g., `wss://somerelay.com`) of a relay the event creator wants to recommend to its followers.
+
+A relay may choose to treat different message kinds differently, and it may or may not choose to have a default way to handle kinds it doesn't know about.
+
+## Other Notes:
+
+- Clients should not open more than one websocket to each relay. One channel can support an unlimited number of subscriptions, so clients should do that.
+- The `tags` array can store a case-sensitive tag name as the first element of each subarray, plus arbitrary information afterward (always as strings). This NIP defines `"p"` — meaning "pubkey", which points to a pubkey of someone that is referred to in the event —, and `"e"` — meaning "event", which points to the id of an event this event is quoting, replying to or referring to somehow. See [NIP-10](10.md) for a detailed description of "e" and "p" tags.
+- The `<recommended relay URL>` item present on the `"e"` and `"p"` tags is an optional (could be set to `""`) URL of a relay the client could attempt to connect to fetch the tagged event or other events from a tagged profile. It MAY be ignored, but it exists to increase censorship resistance and make the spread of relay addresses more seamless across clients.
+- Clients should use the created_at field to judge the age of a metadata event and completely replace older metadata events with newer metadata events regardless of the order in which they arrive.  Clients should not merge any filled fields within older metadata events into empty fields of newer metadata events.
+- When a websocket is closed by the relay with a status code 4000 that means the client shouldn't try to connect again.

+The attestation can be either provided by relays automatically (and the OTS binary contents just appended to the events it receives) or by clients themselves when they first upload the event to relays — and used by clients to show that an event is really "at least as old as [OTS date]".

 Generic Tag Queries
 -------------------
 
-`final` `mandatory` `author:scsibug` `author:fiatjaf`
+`draft` `optional` `author:scsibug` `author:fiatjaf`
 
-Moved to [NIP-01](01.md).
+Relays may support subscriptions over arbitrary tags.  `NIP-01` requires relays to respond to queries for `e` and `p` tags.  This NIP allows any single-letter tag present in an event to be queried.
+
+The `<filters>` object described in `NIP-01` is expanded to contain arbitrary keys with a `#` prefix.  Any single-letter key in a filter beginning with `#` is a tag query, and MUST have a value of an array of strings.  The filter condition matches if the event has a tag with the same name, and there is at least one tag value in common with the filter and event.  The tag name is the letter without the `#`, and the tag value is the second element. Subsequent elements are ignored for the purposes of tag queries. Note that tag names are case-sensitive.
+
+Example Subscription Filter
+---------------------------
+
+The following provides an example of a filter that matches events of kind `1` with an `r` tag set to either `foo` or `bar`.
+
+```
+{
+  "kinds": [1],
+  "#r": ["foo", "bar"]
+}
+```
+
+Client Behavior
+---------------
+
+Clients SHOULD use the `supported_nips` field to learn if a relay supports generic tag queries. Clients MAY send generic tag queries to any relay, if they are prepared to filter out extraneous responses from relays that do not support this NIP.
+
+Rationale
+---------
+
+The decision to reserve only single-letter tags to be usable in queries allow applications to make use of tags for all sorts of metadata, as it is their main purpose, without worrying that they might be bloating relay indexes. That also makes relays more lightweight, of course. And if some application or user is abusing single-letter tags with the intention of bloating relays that becomes easier to detect as single-letter tags will hardly be confused with some actually meaningful metadata some application really wanted to attach to the event with no spammy intentions.
+
+Suggested Use Cases
+-------------------
+
+Motivating examples for generic tag queries are provided below.  This NIP does not promote or standardize the use of any specific tag for any purpose.
+
+* Decentralized Commenting System: clients can comment on arbitrary web pages, and easily search for other comments, by using a `r` ("reference", in this case an URL) tag and value.
+* Location-specific Posts: clients can use a `g` ("geohash") tag to associate a post with a physical location. Clients can search for a set of geohashes of varying precisions near them to find local content.
+* Hashtags: clients can use simple `t` ("hashtag") tags to associate an event with an easily searchable topic name. Since Nostr events themselves are not searchable through the protocol, this provides a mechanism for user-driven search.

+Relays may decide to allow replaceable and/or ephemeral events.
+
+Regular Events
+------------------
+A *regular event* is defined as an event with a kind `1000 <= n < 10000`.
+Upon a regular event being received, the relay SHOULD send it to all clients with a matching filter, and SHOULD store it. New events of the same kind do not affect previous events in any way.
+
+Replaceable Events
+------------------
+A *replaceable event* is defined as an event with a kind `10000 <= n < 20000`.
+Upon a replaceable event with a newer timestamp than the currently known latest replaceable event with the same kind and author being received, the old event SHOULD be discarded,
+effectively replacing what gets returned when querying for
+`author:kind` tuples.
+
+If two events have the same timestamp, the event with the lowest id (first in lexical order) SHOULD be retained, and the other discarded.
+
+Ephemeral Events
+----------------
+An *ephemeral event* is defined as an event with a kind `20000 <= n < 30000`.
+Upon an ephemeral event being received, the relay SHOULD send it to all clients with a matching filter, and MUST NOT store it.
+
+Client Behavior
+---------------
+
+Clients SHOULD use the `supported_nips` field to learn if a relay supports this NIP.  Clients SHOULD NOT send ephemeral events to relays that do not support this NIP; they will most likely be persisted.  Clients MAY send replaceable events to relays that may not support this NIP, and clients querying SHOULD be prepared for the relay to send multiple events and should use the latest one.  
+
+Suggested Use Cases
+-------------------
+
+* States: An application may create a state event that is replaced every time a new state is set (such as statuses)
+* Typing indicators: A chat application may use ephemeral events as a typing indicator.
+* Messaging: Two pubkeys can message over nostr using ephemeral events.

-Moved to [NIP-01](01.md).
+When submitting events to relays, clients currently have no way to know if an event was successfully committed to the database. This NIP introduces the concept of command results which are like NOTICE's except provide more information about if an event was accepted or rejected.
+
+A command result is a JSON object with the following structure that is returned when an event is successfully saved to the database or rejected:
+
+    ["OK", <event_id>, <true|false>, <message>]
+
+Relays MUST return `true` when the event is a duplicate and has already been saved. The `message` SHOULD start with `duplicate:` in this case.
+
+Relays MUST return `false` when the event was rejected and not saved.
+
+The `message` SHOULD provide additional information as to why the command succeeded or failed.
+
+The `message` SHOULD start with `blocked:` if the pubkey or network address has been blocked, banned, or is not on a whitelist.
+
+The `message` SHOULD start with `invalid:` if the event is invalid or doesn't meet some specific criteria (created_at is too far off, id is wrong, signature is wrong, etc)
+
+The `message` SHOULD start with `pow:` if the event doesn't meet some proof-of-work difficulty. The client MAY consult the relay metadata at this point to retrieve the required posting difficulty.
+
+The `message` SHOULD start with `rate-limited:` if the event was rejected due to rate limiting techniques.
+
+The `message` SHOULD start with `error:` if the event failed to save due to a server issue.
+
+Ephemeral events are not acknowledged with OK responses, unless there is a failure.
+
+If the event or `EVENT` command is malformed and could not be parsed, a NOTICE message SHOULD be used instead of a command result. This NIP only applies to non-malformed EVENT commands.
+
+
+Examples
+--------
+
+Event successfully written to the database:
+
+    ["OK", "b1a649ebe8b435ec71d3784793f3bbf4b93e64e17568a741aecd4c7ddeafce30", true, ""]

+
+Event blocked due to ip filter
+
+    ["OK", "b1a649ebe8...", false, "blocked: tor exit nodes not allowed"]
+
+Event blocked due to pubkey ban
+
+    ["OK", "b1a649ebe8...", false, "blocked: you are banned from posting here"]
+
+Event blocked, pubkey not registered
+
+    ["OK", "b1a649ebe8...", false, "blocked: please register your pubkey at https://my-expensive-relay.example.com"]
+
+Event rejected, rate limited
+
+    ["OK", "b1a649ebe8...", false, "rate-limited: slow down there chief"]
+
+Event rejected, `created_at` too far off
+
+    ["OK", "b1a649ebe8...", false, "invalid: event creation date is too far off from the current time. Is your system clock in sync?"]
+
+Event rejected, insufficient proof-of-work difficulty
+
+    ["OK", "b1a649ebe8...", false, "pow: difficulty 26 is less than 30"]
+
+Event failed to save, 
+
+    ["OK", "b1a649ebe8...", false, "error: could not connect to the database"]
+
+
+
+Client Handling
+---------------
+
+`messages` are meant for humans, with `reason:` prefixes so that clients can be slightly more intelligent with what to do with them. For example, with a `rate-limited:` reason the client may not show anything and simply try again with a longer timeout.
+
+For the `pow:` prefix it may query relay metadata to get the updated difficulty requirement and try again in the background.
+
+For the `invalid:` and `blocked:` prefix the client may wish to show these as styled error popups.
+
+The prefixes include a colon so that the message can be cleanly separated from the prefix by taking everything after `:` and trimming it.
+
+
+Future Extensions
+-----------------
+
+This proposal SHOULD be extended to support further commands in the future, such as REQ and AUTH. They are left out of this initial version to keep things simpler.

 Parameterized Replaceable Events

+`draft` `optional` `author:Semisol` `author:Kukks` `author:Cameri` `author:Giszmo`
 
-Moved to [NIP-01](01.md).
+This NIP adds a new event range that allows for replacement of events that have the same `d` tag and kind unlike NIP-16 which only replaced by kind.
+
+Implementation
+--------------
+The value of a tag can be any string and is defined as the first parameter of a tag after the tag name.
+
+A *parameterized replaceable event* is defined as an event with a kind `30000 <= n < 40000`.
+Upon a parameterized replaceable event with a newer timestamp than the currently known latest
+replaceable event with the same kind, author and first `d` tag value being received, the old event
+SHOULD be discarded, effectively replacing what gets returned when querying for
+`author:kind:d-tag` tuples.
+
+If two events have the same timestamp, the event with the lowest id (first in lexical order) SHOULD be retained, and the other discarded.
+
+A missing or a `d` tag with no value should be interpreted equivalent to a `d` tag with the
+value as an empty string. Events from the same author with any of the following `tags`
+replace each other:
+
+* `"tags":[["d",""]]`
+* `"tags":[]`: implicit `d` tag with empty value
+* `"tags":[["d"]]`: implicit empty value `""`
+* `"tags":[["d",""],["d","not empty"]]`: only first `d` tag is considered
+* `"tags":[["d"],["d","some value"]]`: only first `d` tag is considered
+* `"tags":[["e"]]`: same as no tags
+* `"tags":[["d","","1"]]`: only the first value is considered (`""`)
+
+Clients SHOULD NOT use `d` tags with multiple values and SHOULD include the `d` tag even if it has no value to allow querying using the `#d` filter.
+
+Referencing and tagging
+-----------------------
+
+Normally (as per NIP-01, NIP-12) the `"p"` tag is used for referencing public keys and the
+`"e"` tag for referencing event ids and the `note`, `npub`, `nprofile` or `nevent` are their
+equivalents for event tags (i.e. an `nprofile` is generally translated into a tag
+`["p", "<event hex id>", "<relay url>"]`).
+
+To support linking to parameterized replaceable events, the `naddr` code is introduced on
+NIP-19. It includes the public key of the event author and the `d` tag (and relays) such that
+the referenced combination of public key and `d` tag can be found.
+
+The equivalent in `tags` to the `naddr` code is the tag `"a"`, comprised of `["a", "<kind>:<pubkey>:<d-identifier>", "<relay url>"]`.
+
+Client Behavior
+---------------
+
+Clients SHOULD use the `supported_nips` field to learn if a relay supports this NIP.
+Clients MAY send parameterized replaceable events to relays that may not support this NIP, and clients querying SHOULD be prepared for the relay to send multiple events and should use the latest one and are recommended to send a `#d` tag filter. Clients should account for the fact that missing `d` tags or ones with no value are not returned in tag filters, and are recommended to always include a `d` tag with a value.

-User Statuses
---------------

-`draft` `optional` `author:jb55`
-
-## Abstract
-
-This NIP enables a way for users to share live statuses such as what music they are listening to, as well as what they are currently doing: work, play, out of office, etc.
-
-## Live Statuses
-
-A special event with `kind:30315` "User Status" is defined as an *optionally expiring* _parameterized replaceable event_, where the `d` tag represents the status type:
-
-For example:
-
-```js
-{
-  "kind": 30315,
-  "content": "Sign up for nostrasia!",
-  "tags": [
-    ["d", "general"],
-    ["r", "https://nostr.world"]
-  ],
-}
-
-{
-  "kind": 30315,
-  "content": "Intergalatic - Beastie Boys",
-  "tags": [
-    ["d", "music"],
-    ["r", "spotify:search:Intergalatic%20-%20Beastie%20Boys"],
-    ["expiration", "1692845589"]
-  ],
-}
-```
-
-Two common status types are defined: `general` and `music`. `general` represent general statuses: "Working", "Hiking", etc.
-
-`music` status events are for live streaming what you are currently listening to. The expiry of the `music` status should be when the track will stop playing.
-
-Any other status types can be used but they are not defined by this NIP.
-
-The status MAY include an `r`, `p`, `e` or `a` tag linking to a URL, profile, note, or parameterized replaceable event.
-
-# Client behavior
-
-Clients MAY display this next to the username on posts or profiles to provide live user status information.
-
-# Use Cases
-
-* Calendar nostr apps that update your general status when you're in a meeting
-* Nostr Nests that update your general status with a link to the nest when you join
-* Nostr music streaming services that update your music status when you're listening
-* Podcasting apps that update your music status when you're listening to a podcast, with a link for others to listen as well
-* Clients can use the system media player to update playing music status
-
-The `content` MAY include emoji(s), or [NIP-30](30.md) custom emoji(s). If the `content` is an empty string then the client should clear the status.

+Encrypted Payloads (Versioned)
+------------------------------
+
+`optional` `author:paulmillr` `author:staab`
+
+The NIP introduces a new data format for keypair-based encryption. This NIP is versioned to allow multiple algorithm choices to exist simultaneously.
+
+An encrypted payload MUST be encoded as a JSON object. Different versions may have different parameters. Every format has a `v` field specifying its version.
+
+Currently defined encryption algorithms:
+
+- `0x00` - Reserved
+- `0x01` - XChaCha with same key `sha256(ecdh)` per conversation
+
+# Version 1
+
+Params:
+
+1. `nonce`: base64-encoded xchacha nonce
+2. `ciphertext`: base64-encoded xchacha ciphertext, created from (key, nonce) against `plaintext`.
+
+Example:
+
+- Alice's private key: `5c0c523f52a5b6fad39ed2403092df8cebc36318b39383bca6c00808626fab3a`
+- Bob's private key: `4b22aa260e4acb7021e32f38a6cdf4b673c6a277755bfce287e370c924dc936d`
+
+Encrypting the message `hello` from Alice to Bob results in the base-64 encoded tlv payload:
+
+```
+AZKyMIHbfVYFlAAK7Ci5wuM5GFOLaeI7LQKDzWJY
+```
+
+# Other Notes
+
+By default in the [libsecp256k1](https://github.com/bitcoin-core/secp256k1) ECDH implementation, the secret is the SHA256 hash of the shared point (both X and Y coordinates). We are using this exact implementation. In NIP-94, unhashed shared point was used.
+
+This encryption scheme replaces the one described in NIP-04, which is not secure. It used bad cryptographic building blocks and must not be used.

-
-## Nostr Event
-
-A `kind:9041` event is used.
-
-The `.content` contains a human-readable description of the goal.
-
-The following tags are defined as REQUIRED.
-
-- `amount` - target amount in milisats.
-- `relays` - a list of relays the zaps to this goal will be sent to and tallied from.
-
-Example event:
-
-```json

-
-The following tags are OPTIONAL.

-  ],
-  "content": "Nostrasia travel expenses",
-  ...other fields
-```
-
-The goal MAY include an `r` or `a` tag linking to a URL or parameterized replaceable event.
-
-The goal MAY include multiple beneficiary pubkeys by specifying [`zap` tags](57.md#appendix-g-zap-tag-on-other-events).
-
-Parameterized replaceable events can link to a goal by using a `goal` tag specifying the event id and an optional relay hint.
-

-  "tags": [
-    ...
-    ["goal", "<event id>", "<Relay URL (optional)>"],

-
-## Client behavior
-
-Clients MAY display funding goals on user profiles.
-
-When zapping a goal event, clients MUST include the relays in the `relays` tag of the goal event in the zap request `relays` tag.
-
-When zapping a parameterized replaceable event with a `goal` tag, clients SHOULD tag the goal event id in the `e` tag of the zap request.

-`draft` `optional` `author:pablof7z`
-
-This NIP defines a way for a pubkey to create recurring subscription payments to another pubkey.
-
-## Tier Event
-A pubkey can create "tiers". These tiers might provide certain benefits to the supporters who subscribe to these.
-
-```json
-{
-    "kind": 7002,
-    "content": "<description of the tier>",
-    "tags": [
-        [ "title", "..." ],
-        [ "amount", "<amount-in-base-unit>", "currency", "<cadence>" ]
-    ]
-}
-```
-
-This event is generated by a pubkey who wants to allow users to support with different tiers.
-
-`.content` SHOULD be a description of what users who subscribe can expect.
-Tag `title` is an optional title for the tier.
-Tag `amount` MUST specify the payment required for this tier and its cadence.
-    * The first argument should be the stringified amount and the second argument the currency
-    * The third argument SHOULD be one of `daily`, `monthly`, `yearly`
-One or more `amount` tags MUST exist.
-
-#### Examples
-* `[ "amount", "100", "usd", "daily" ]`, $1.00 a day.
-* `[ "amount", "1000000", "btc", "daily" ]`, 1000000 millisats a day.
-
-## Subscribe Event
-
-```json
-{
-    "kind": 7001,
-    "content": "<optional-message>",
-    "tags": [
-        [ "p", "<recipient-pubkey>" ],
-        [ "e", "<supporting-tier-id>" ],
-        [ "amount", "<amount-in-base-unit>", "currency", "<cadence>" ]
-    ]
-}
-```
-
-When a user wants to subscribe to subscribe to support a user they create a `kind:7001` event.
-
-* `.content` is an optional message the supporter can write.
-* The `p` tag MUST tag the pubkey being supported.
-* The `e` tag is optional, and should point to a `kind:7001` support tier event. There MUST be exactly 0 or 1 `e` tags.
-* The `amount` tag specifies what the supporters is committing to pay to the supported pubkey and the candence.
-
-The `kind:7001` event can be created without an `e` tag so that users can create recurring support events without the pubkey receiving the support having explicitly created a support tier.
-
-## Paying
-The supporting user should create a zap p-tagging the receiver and e-tagging the `kind:7001`. There MUST be a single `p` and a single `e` tag in the zap request.

-Data Vending Machine
---------------------
-
-`draft` `optional` `author:pablof7z` `author:dontbelievethehype`
-
-This NIP defines the interaction between customers and Service Providers for performing on-demand computation.
-
-Money in, data out.
-
-## Kinds
-This NIP reserves the range `5000-7000` for data vending machine use.
-
-| Kind | Description |
-| ---- | ----------- |
-| 5000-5999 | Job request kinds |
-| 6000-6999 | Job result |
-| 7000 | Job feedback |
-
-Job results always use a kind number that is `1000` higher than the job request kind. (e.g. request: `kind:5001` gets a result: `kind:6001`).
-
-Job request types are defined [separately](https://github.com/nostr-protocol/data-vending-machines/tree/master/kinds).
-
-## Rationale
-Nostr can act as a marketplace for data processing, where users request jobs to be processed in certain ways (e.g., "speech-to-text", "summarization", etc.), but they don't necessarily care about "who" processes the data.
-
-This NIP is not to be confused with a 1:1 marketplace; instead, it describes a flow where a user announces a desired output, willingness to pay, and service providers compete to fulfill the job requirement in the best way possible.
-
-### Actors
-There are two actors in the workflow described in this NIP:
-* Customers (npubs who request a job)
-* Service providers (npubs who fulfill jobs)
-
-## Job request (`kind:5000-5999`)
-A request to process data, published by a customer. This event signals that an customer is interested in receiving the result of some kind of compute.
-
-```json
-{
-    "kind": 5xxx, // kind in 5000-5999 range
-    "content": "",
-    "tags": [
-        [ "i", "<data>", "<input-type>", "<relay>", "<marker>" ],
-        [ "output", "<mime-type>" ],
-        [ "relays", "wss://..." ],
-        [ "bid", "<msat-amount>" ],
-        [ "t", "bitcoin" ]
-    ]
-}
-```
-
-All tags are optional.
-
-* `i` tag: Input data for the job (zero or more inputs)
-    * `<data>`: The argument for the input
-    * `<input-type>`: The way this argument should be interpreted. MUST be one of:
-        * `url`: A URL to be fetched of the data that should be processed.
-        * `event`: A Nostr event ID.
-        * `job`: The output of a previous job with the specified event ID. The dermination of which output to build upon is up to the service provider to decide (e.g. waiting for a signaling from the customer, waiting for a payment, etc.)
-        * `text`: `<data>` is the value of the input, no resolution is needed
-    * `<relay>`: If `event` or `job` input-type, the relay where the event/job was published, otherwise optional or empty string
-    * `<marker>`: An optional field indicating how this input should be used within the context of the job
-* `output`: Expected output format. Different job request `kind` defines this more precisely.
-* `param`: Optional parameters for the job as key (first argument)/value (second argument). Different job request `kind` defines this more precisely. (e.g. `[ "param", "lang", "es" ]`)
-* `bid`: Customer MAY specify a maximum amount (in millisats) they are willing to pay
-* `relays`: List of relays where Service Providers SHOULD publish responses to
-* `p`: Service Providers the customer is interested in. Other SPs MIGHT still choose to process the job
-
-## Job result (`kind:6000-6999`)
-
-Service providers publish job results, providing the output of the job result. They should tag the original job request event id as well as the customer's pubkey.
-
-```json
-{
-    "pubkey": "<service-provider pubkey>",
-    "content": "<payload>",
-    "kind": 6xxx,
-    "tags": [
-        [ "request", "<job-request>" ],
-        [ "e", "<job-request-id>", "<relay-hint>" ],
-        [ "i", "<input-data>" ],
-        [ "p", "<customer's-pubkey>" ],
-        [ "amount", "requested-payment-amount", "<optional-bolt11>" ]
-    ]
-}
-```
-
-* `request`: The job request event stringified-JSON.
-* `amount`: millisats that the Service Provider is requesting to be paid. An optional third value can be a bolt11 invoice.
-* `i`: The original input(s) specified in the request.
-
-## Job feedback
-Service providers can give feedback about a job back to the customer.
-
-```json
-{
-    "kind": 7000,
-    "content": "<empty-or-payload>",
-    "tags": [
-        [ "status", "<status>", "<extra-info>" ],
-        [ "amount", "requested-payment-amount", "<bolt11>" ],
-        [ "e", "<job-request-id>", "<relay-hint>" ],
-        [ "p", "<customer's-pubkey>" ],
-    ]
-}
-```
-
-* `content`: Either empty or a job-result (e.g. for partial-result samples)
-* `amount` tag: as defined in the [Job Result](#job-result) section.
-* `status` tag: Service Providers SHOULD indicate what this feedback status refers to. [Appendix 1](#appendix-1-job-feedback-status) defines status. Extra human-readable information can be added as an extra argument.
-
-### Job feedback status
-
-| status | description |
-|--------|-------------|
-| `payment-required` | Service Provider requires payment before continuing. |
-| `processing` | Service Provider is processing the job. |
-| `error` | Service Provider was unable to process the job. |
-| `success` | Service Provider successfully processed the job. |
-| `partial` | Service Provider partially processed the job. The `.content` might include a sample of the partial results. |
-
-Any job feedback event MIGHT include results in the `.content` field, as described in the [Job Result](#job-result) section. This is useful for service providers to provide a sample of the results that have been processed so far.
-
-
-# Protocol Flow
-* Customer publishes a job request (e.g. `kind:5000` speech-to-text).
-* Service Providers MAY submit `kind:7000` job-feedback events (e.g. `payment-required`, `processing`, `error`, etc.).
-* Upon completion, the service provider publishes the result of the job with a `kind:6000` job-result event.
-* At any point, if there is an `amount` pending to be paid as instructed by the service provider, the user can pay the included `bolt11` or zap the job result event the service provider has sent to the user
-
-Job feedback (`kind:7000`) and Job Results (`kind:6000-6999`) events MAY include an `amount` tag, this can be interpreted as a suggestion to pay. Service Providers MUST use the `payment-required` feedback event to signal that a payment is required and no further actions will be performed until the payment is sent.
-
-Customers can always either pay the included `bolt11` invoice or zap the event requesting the payment and service providers should monitor for both if they choose to include a bolt11 invoice.
-
-## Notes about the protocol flow
-The flow is deliberately ambiguous, allowing vast flexibility for the interaction between customers and service providers so that service providers can model their behavior based on their own decisions/perceptions of risk.
-
-Some service providers might choose to submit a `payment-required` as the first reaction before sending a `processing` or before delivering results, some might choose to serve partial results for the job (e.g. a sample), send a `payment-required` to deliver the rest of the results, and some service providers might choose to assess likelihood of payment based on an npub's past behavior and thus serve the job results before requesting payment for the best possible UX.
-
-It's not up to this NIP to define how individual vending machines should choose to run their business.
-
-# Cancellation
-A job request might be cancelled by publishing a `kind:5` delete request event tagging the job request event.
-
-# Appendix 1: Job chaining
-A Customer MAY request multiple jobs to be processed as a chain, where the output of a job is the input of another job. (e.g. podcast transcription -> summarization of the transcription). This is done by specifying as input an event id of a different job with the `job` type.
-
-Service Providers MAY begin processing a subsequent job the moment they see the prior job's result, but they will likely wait for a zap to be published first. This introduces a risk that Service Provider of job #1 might delay publishing the zap event in order to have an advantage. This risk is up to Service Providers to mitigate or to decide whether the service provider of job #1 tends to have good-enough results so as to not wait for an explicit zap to assume the job was accepted.
-
-This gives a higher level of flexibility to service providers (which sophisticated service providers would take anyway).
-
-# Appendix 2: Service provider discoverability
-Service Providers MAY use NIP-89 announcements to advertise their support for job kinds:
-
-```json
-{
-    "kind": 31990,
-    "pubkey": "<pubkey>",
-    "content": "{
-        \"name\": \"Translating DVM\",
-        \"about\": \"I'm a DVM specialized in translating Bitcoin content.\"
-    }",
-    "tags": [
-        [ "k", "5005" ], // e.g. translation
-        [ "t", "bitcoin" ] // e.g. optionally advertises it specializes in bitcoin audio transcription that won't confuse "Drivechains" with "Ridechains"
-    ]
-}
-```
-
-Customers can use NIP-89 to see what service providers their follows use.
