- No whitespace, line breaks or other unnecessary formatting should be included in the output JSON.
- No characters except the following should be escaped, and instead should be included verbatim:
- A line break, `0x0A`, as `\n`
- A double quote, `0x22`, as `\"`
- A backslash, `0x5C`, as `\\`
- A carriage return, `0x0D`, as `\r`
- A tab character, `0x09`, as `\t`
- A backspace, `0x08`, as `\b`
- A form feed, `0x0C`, as `\f`
- UTF-8 should be used for encoding.

This NIP defines one basic kind:
- `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.

[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.

Relays SHOULD continue to publish/share the deletion events indefinitely, as clients may already have the event that's intended to be deleted. Additionally, clients SHOULD broadcast deletion events to other relays which don't have it.
When an `a` tag is used, relays SHOULD delete all versions of the replaceable event up to the `created_at` timestamp of the deletion event.
## Client Usage
Clients MAY choose to fully hide any events that are referenced by valid deletion events. This includes text notes, direct messages, or other yet-to-be defined event kinds. Alternatively, they MAY show the event along with an icon or other indication that the author has "disowned" the event. The `content` field MAY also be used to replace the deleted events' own content, although a user interface should clearly indicate that this is a deletion reason, not the original content.

======
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.
```js
{
"id": "<usual hash>",
  "pubkey": "<sender-pubkey>",
"created_at": now(),
  "kind": 14,
  "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>"],
    ...
  ],
  "content": "<message-in-plain-text>",
}
```
`.content` MUST be plain text. Fields `id` and `created_at` are required.
Tags that mention, quote and assemble threading structures MUST follow [NIP-10](10.md).
Kind `14`s MUST never be signed. If it is signed, the message might leak to relays and become **fully public**.
## 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 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 thread is the subject of the conversation.
## Encrypting
Following [NIP-59](59.md), the **unsigned** `kind:14` chat message 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.
```js
{
"kind": 10050,
"tags": [
["relay", "wss://inbox.nostr.wine"],
["relay", "wss://myrelay.nostr1.com"],
],
"content": "",
//...other fields
}
```
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:14` 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`.
The two final GiftWraps, one to the receiver and the other to the sender, are:

Quote reposts are `kind 1` events with an embedded `e` tag

an `e` tag, it may show up along replies to the reposted note.
Quote reposts are `kind 1` events with an embedded `q` tag of the note being

NIP-29
======
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 parameterized replaceable 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`.
## 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.
## Event definitions
- *text root note* (`kind:11`)
This is the basic unit of a "microblog" root text note sent to a group.
```js
"kind": 11,
"content": "hello my friends lovers of pizza",
"tags": [
["h", "<group-id>"],
["previous", "<event-id-first-chars>", "<event-id-first-chars>", ...]
]
...
```
- *threaded text reply* (`kind:12`)
This is the basic unit of a "microblog" reply note sent to a group. It's the same as `kind:11`, except for the fact that it must be used whenever it's in reply to some other note (either in reply to a `kind:11` or a `kind:12`). `kind:12` events SHOULD use NIP-10 markers, leaving an empty relay url:
* `["e", "<kind-11-root-id>", "", "root"]`
* `["e", "<kind-12-event-id>", "", "reply"]`
- *chat message* (`kind:9`)
This is the basic unit of a _chat message_ sent to a group.
```js
"kind": 9,
"content": "hello my friends lovers of pizza",
"tags": [
["h", "<group-id>"],
["previous", "<event-id-first-chars>", "<event-id-first-chars>", ...]
]
...
```
- *chat message threaded reply* (`kind:10`)
Similar to `kind:12`, this is the basic unit of a chat message sent to a group. This is intended for in-chat threads that may be hidden by default. Not all in-chat replies MUST use `kind:10`, only when the intention is to create a hidden thread that isn't part of the normal flow of the chat (although clients are free to display those by default too).
`kind:10` SHOULD use NIP-10 markers, just like `kind:12`.
- *join request* (`kind:9021`)
Any user can send one of these events to the relay in order to be automatically or manually added to the group. If the group is `open` the relay will automatically issue a `kind:9000` in response adding this user. Otherwise group admins may choose to query for these requests and act upon them.
```js
{
"kind": 9021,
"content": "optional reason",
"tags": [
["h", "<group-id>"]
]
}
```
- *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. The relay may discard the event after taking action or keep it as a moderation log.
```js
{
"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 | `add-user` | `p` (pubkey hex) |
| 9001 | `remove-user` | `p` (pubkey hex) |
| 9002 | `edit-metadata` | `name`, `about`, `picture` (string) |
| 9003 | `add-permission` | `p` (pubkey), `permission` (name) |
| 9004 | `remove-permission` | `p` (pubkey), `permission` (name) |
| 9005 | `delete-event` | `e` (id hex) |
| 9006 | `edit-group-status` | `public` or `private`, `open` or `closed` |
| 9007 | `create-group` | |
- *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.
```js
{
"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"]
]
...
}
```
`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)
Similar to the group metadata, this event is supposed to be generated by relays that host the group.
Each admin gets a label that is only used for display purposes, and a list of permissions it has are listed afterwards. These permissions can inform client building UI, but ultimately are evaluated by the relay in order to become effective.
The list of capabilities, as defined by this NIP, for now, is the following:
- `add-user`
- `edit-metadata`
- `delete-event`
- `remove-user`
- `add-permission`
- `remove-permission`
- `edit-group-status`
```js
{
"kind": 39001,
"content": "list of admins for the pizza lovers group",
"tags": [
["d", "<group-id>"],
["p", "<pubkey1-as-hex>", "ceo", "add-user", "edit-metadata", "delete-event", "remove-user"],
["p", "<pubkey2-as-hex>", "secretary", "add-user", "delete-event"]
]
...
}
```
- *group members* (`kind:39002`) (optional)
Similar to *group admins*, this event is supposed to be generated by relays that host the group.
It's a NIP-51-like list of pubkeys that are members of the group. Relays might choose to not to publish this information or to restrict what pubkeys can fetch it.
```json
{
"kind": 39002,
"content": "list of members for the pizza lovers group",
"tags": [
["d", "<group-id>"],
["p", "<admin1>"],
["p", "<member-pubkey1>"],
["p", "<member-pubkey2>"],
]
}
```
## Storing the list of groups a user belongs to
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.

======
`git` stuff
-----------
`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>", ...]
]
}
```
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.
## 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 `e` `reply` tag pointing to the previous patch.
The first patch revision in a patch revision SHOULD include a NIP-10 `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"], // ommited 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.
```jsonc
{
"kind": 1621,
"content": "<markdown text>",
"tags": [
["a", "30617:<base-repo-owner-pubkey>:<base-repo-id>"],
["p", "<repository-owner>"]
]
}
```
## Replies
Replies are also Markdown text. The difference is that they MUST be issued as replies to either a `kind:1621` _issue_ or a `kind:1617` _patch_ event. The threading of replies and patches should follow NIP-10 rules.
```jsonc
{
"kind": 1622,
"content": "<markdown text>",
"tags": [
["a", "30617:<base-repo-owner-pubkey>:<base-repo-id>", "<relay-url>"],
["e", "<issue-or-patch-id-hex>", "", "root"],
// other "e" and "p" tags should be applied here when necessary, following the threading rules of NIP-10
["p", "<patch-author-pubkey-hex>", "", "mention"],
["e", "<previous-reply-id-hex>", "", "reply"],
// ...
]
}
```
## 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 Status event with the largest created_at date is valid.
The Status of a patch-revision defaults to either that of the root-patch, or `1632` (Closed) if the root-patch's Status is `1631` and the patch-revision isn't tagged in the `1631` event.

- inline file comments kind (we probably need one for patches and a different one for merged files)

NIP-35
======
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.
```jsonc
{
"kind": 2003,
"content": "<long-description-pre-formatted>",
"tags": [
["title", "<torrent-title>"],
["x", "<bittorrent-info-hash>"],

["i", "tmdb:movie:693134"],
["i", "ttvdb:movie:290272"],
["t", "movie"],
["t", "4k"],
]
}
```
## 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.

NIP-54
======
Wiki
----
`draft` `optional`
This NIP defines `kind:30818` (a _parameterized replaceable event_) for long-form text content similar to [NIP-23](23.md), but with one important difference: articles are meant to be 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
```jsonc
{
"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 rules
The content should be Markdown, following the same rules as of [NIP-23](23.md), although it takes some extra (optional) metadata 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.
One extra functionality is added: **wikilinks**. Unlike normal Markdown links `[]()` that link to 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`.
### 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 Markdown?
-------------
If the idea is to make a wiki then the most obvious text format to use is probably the mediawiki/wikitext format used by Wikipedia since it's widely deployed in all mediawiki installations and used for decades with great success. However, it turns out that format is very bloated and convoluted, has way too many features and probably because of that it doesn't have many alternative implementations out there, and the ones that exist are not complete and don't look very trustworthy. Also it is very much a centralized format that can probably be changed at the whims of the Wikipedia owners.
On the other hand, Markdown has proven to work well for small scale wikis and one of the biggest wikis in the planet (which is not very often thought of as a wiki), [StackOverflow](https://stackoverflow.com) and its child sites, and also one of the biggest "personal wiki" software, [Obsidian](https://obsidian.md/). Markdown can probably deliver 95% of the functionality of wikitext. When augmented with tables, diagram generators and MathJax (which are common extensions that exist in the wild and can be included in this NIP) that rate probably goes to 99%, and its simplicity is a huge benefit that can't be overlooked. Wikitext format can also be transpíled into Markdown using Pandoc. Given all that, I think it's a reasonable suspicion that mediawiki is not inherently better than Markdown, the success of Wikipedia probably cannot be predicated on the syntax language choice.
# 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.
```jsonc
{
"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 (the pubkey being requested to merge something into their article can create [[NIP-25]] reactions that tag the `kind:818` event with `+` or `-`

# NIP-55
## Android Signer Application
`draft` `optional`
This NIP describes a method for 2-way communication between an Android signer and any Nostr client on Android. The Android signer is an Android Application and the client can be a web client or an Android application.
# Usage for Android applications
The Android signer uses Intents and Content Resolvers 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 signature = activityResult.data?.getStringExtra("signature")
// Do something with signature ...
}
}
)
```
Create the Intent using the **nostrsigner** scheme:
```kotlin
val intent = Intent(Intent.ACTION_VIEW, Uri.parse("nostrsigner:$content"))
```
Set the Signer package name:
```kotlin
intent.`package` = "com.example.signer"
```
Send the Intent:
```kotlin
launcher.launch(intent)
```
### Methods
- **get_public_key**
- params:
```kotlin
val intent = Intent(Intent.ACTION_VIEW, Uri.parse("nostrsigner:"))
intent.`package` = "com.example.signer"
intent.putExtra("type", "get_public_key")
// You can send some default permissions for the user to authorize for ever
val permissions = listOf(
Permission(
type = "sign_event",
kind = 22242
),
Permission(
type = "nip44_decrypt"
)
)
intent.putExtra("permissions", permissions.toJson())
context.startActivity(intent)
```
- result:
- If the user approved intent it will return the **npub** in the signature field
```kotlin
val npub = intent.data?.getStringExtra("signature")
// The package name of the signer application
val packageName = intent.data?.getStringExtra("package")
```
- **sign_event**
- params:
```kotlin
val intent = Intent(Intent.ACTION_VIEW, Uri.parse("nostrsigner:$eventJson"))

// To handle results when not waiting between intents
intent.putExtra("id", event.id)
// Send the current logged in user npub
intent.putExtra("current_user", npub)
context.startActivity(intent)
```
- result:
- If the user approved intent it will return the **signature**, **id** and **event** fields
```kotlin
val signature = intent.data?.getStringExtra("signature")
// The id you sent
val id = intent.data?.getStringExtra("id")
val signedEventJson = intent.data?.getStringExtra("event")
```
- **nip04_encrypt**
- params:
```kotlin
val intent = Intent(Intent.ACTION_VIEW, Uri.parse("nostrsigner:$plaintext"))
intent.`package` = "com.example.signer"
intent.putExtra("type", "nip04_encrypt")
// to control the result in your application in case you are not waiting the result before sending another intent
intent.putExtra("id", "some_id")
// Send the current logged in user npub
intent.putExtra("current_user", account.keyPair.pubKey.toNpub())
// Send the hex pubKey that will be used for encrypting the data
intent.putExtra("pubKey", pubKey)
context.startActivity(intent)
```
- result:
- If the user approved intent it will return the **signature** and **id** fields
```kotlin
val encryptedText = intent.data?.getStringExtra("signature")
// the id you sent
val id = intent.data?.getStringExtra("id")
```
- **nip44_encrypt**
- params:
```kotlin
val intent = Intent(Intent.ACTION_VIEW, Uri.parse("nostrsigner:$plaintext"))
intent.`package` = "com.example.signer"
intent.putExtra("type", "nip44_encrypt")
// to control the result in your application in case you are not waiting the result before sending another intent
intent.putExtra("id", "some_id")
// Send the current logged in user npub
intent.putExtra("current_user", account.keyPair.pubKey.toNpub())
// Send the hex pubKey that will be used for encrypting the data
intent.putExtra("pubKey", pubKey)
context.startActivity(intent)
```
- result:
- If the user approved intent it will return the **signature** and **id** fields
```kotlin
val encryptedText = intent.data?.getStringExtra("signature")
// the id you sent
val id = intent.data?.getStringExtra("id")
```
- **nip04_decrypt**

## 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 npub 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 "signature" and "event". The column event is the signed event json
For the other types Signer Application returns the column "signature"
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
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

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](https://github.com/nostr-protocol/nips/blob/master/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`:

```
## 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. These video events are _parameterized replaceable_ and deletable per [NIP-09](09.md).
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: horizontal and vertical video events. This is meant to allow clients to cater to each as the viewing experience for horizontal (landscape) videos is often different than that of vertical (portrait) videos (Stories, Reels, Shorts, etc).
#### Format
The format uses a parameterized replaceable event kind `34235` for horizontal videos and `34236` for vertical videos.
The `.content` of these events is a summary or description on the video content.
The list of tags are as follows:
* `d` (required) universally unique identifier (UUID). Generated by the client creating the video event.
* `url` (required) the url to the video file
* `m` a string indicating the data type of the file. The [MIME types](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Common_types) format must be used, and they should be lowercase.
* `title` (required) title of the video
* `"published_at"`, for the timestamp in unix seconds (stringified) of the first time the video was published
* `x` containing the SHA-256 hexencoded string of the file.
* `size` (optional) size of file in bytes
* `dim` (optional) size of file in pixels in the form `<width>x<height>`
* `duration` (optional) video duration in seconds
* `magnet` (optional) URI to magnet file
* `i` (optional) torrent infohash
* `text-track` (optional, repeated) link to WebVTT file for video, type of supplementary information (captions/subtitles/chapters/metadata), optional language code
* `thumb` (optional) url of thumbnail with same aspect ratio
* `image` (optional) url of preview image with same dimensions
* `content-warning` (optional) warning about content of NSFW video
* `alt` (optional) description for accessibility
* `segment` (optional, repeated) start timestamp in format `HH:MM:SS.sss`, end timestamp in format `HH:MM:SS.sss`, chapter/segment title, chapter thumbnail-url
* `t` (optional, repeated) hashtag to categorize video
* `p` (optional, repeated) 32-bytes hex pubkey of a participant in the video, optional recommended relay URL
* `r` (optional, repeated) references / links to web pages
```json

}
```
## Video View
A video event view is a response to a video event to track a user's view or progress viewing the video.
### Format
The format uses a parameterized replaceable event kind `34237`.
The `.content` of these events is optional and could be a free-form note that acts like a bookmark for the user.
The list of tags are as follows:
* `a` (required) reference tag to kind `34235` or `34236` video event being viewed
* `d` (required) same as `a` reference tag value
* `viewed` (optional, repeated) timestamp of the user's start time in seconds, timestamp of the user's end time in seconds
```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": 34237,
"content": "<note>",
"tags": [
["a", "<34235 | 34236>:<video event author pubkey>:<d-identifier of video event>", "<optional relay url>"],
["e", "<event-id", "<relay-url>"]
["d", "<34235 | 34236>:<video event author pubkey>:<d-identifier of video event>"],
["viewed", <start>, <end>],
]
}

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. Since relays are instructed to delete old versions of a replaceable event, the `.content` of an `e`-approval MUST have the specific version of the event or Clients might not be able to find that version of the content anywhere.

## 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
A file can be uploaded one at a time to `https://your-file-server.example/custom-api-path` (route from `https://your-file-server.example/.well-known/nostr/nip96.json` "api_url" field) as `multipart/form-data` content type using `POST` method with the file object set to the `file` form data field.
`POST $api_url` as `multipart/form-data`.
`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).
If using an html form, use an `Authorization` form data field instead.
**AUTH required**
These following **optional** form data fields MAY be used by `servers` and SHOULD be sent by `clients`:
- `expiration`: string of the UNIX timestamp in seconds. Empty string if file should be stored forever. The server isn't required to honor this;
- `size`: string of the 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;
- `caption`: loose description;
- `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;
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`.
Note for `clients`: if using an HTML form, it is important for the `file` form field to be the **last** one, or be re-ordered right before sending or be appended as the last field of XHR2's FormData object.
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 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 (which is embedded in the decoded header value) as the owner of the file so to later allow them to delete the file.
Note that if a file with the same hash of a previously received file (so the same file) is uploaded by another user, the server doesn't need to store the new file.
It should just add the new user's `pubkey` to the list of the owners of the already stored file with said hash (if it wants to save space by keeping just one copy of the same file, because multiple uploads of the same file results in the same file hash).
The `server` MUST link the user's `pubkey` string as the owner of the file so to later allow them to delete the file.
The `server` MAY also store the `Authorization` header/field value (decoded or not) for accountability purpose as this proves that the user with the unique pubkey did ask for the upload of the file with a specific hash. However, storing the pubkey is sufficient to establish ownership.
`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.
The `server` MUST reject with 413 Payload Too Large if file size exceeds limits.
### Response codes
The `server` MUST reject with 400 Bad Request status if some fields are invalid.
The `server` MUST reply to the upload with 200 OK status if the `payload` tag value contains an already used SHA-256 hash (if file is already owned by the same pubkey) or reject the upload with 403 Forbidden status if it isn't the same of the received file.
The `server` MAY reject the upload with 402 Payment Required status if the user has a pending payment (Payment flow is not strictly required. Server owners decide if the storage is free or not. Monetization schemes may be added later to correlated NIPs.).
On successful uploads the `server` MUST reply with **201 Created** HTTP status code or **202 Accepted** if a `processing_url` field is added
to the response so that the `client` can follow the processing status (see [Delayed Processing](#delayed-processing) section).
- `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**.

## Criteria for acceptance of NIPs
1. They should be implemented in at least two clients and one relay -- when applicable.
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.
