### Kinds ### Kinds
Kinds specify how clients should interpret the meaning of each event and the other fields of each event (e.g. an `"r"` tag may have a meaning in an event of kind 1 and an entirely different meaning in an event of kind 10002). Each NIP may define the meaning of a set of kinds that weren't defined elsewhere. This NIP defines two basic kinds: Kinds specify how clients should interpret the meaning of each event and the other fields of each event (e.g. an `"r"` tag may have a meaning in an event of kind 1 and an entirely different meaning in an event of kind 10002). Each NIP may define the meaning of a set of kinds that weren't defined elsewhere. 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. - `0`: **user metadata**: the `content` is set to a stringified JSON object `{name: <username>, about: <string>, picture: <url, string>}` describing the user who created the event. [Extra metadata fields](24.md#kind-0) may be set. A relay may delete older events once it gets a new one for the same pubkey.
- `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. - `1`: **text note**: the `content` is set to the **plaintext** content of a note (anything the user wants to say).

## Notes ## Notes
### Identification, not verification
The NIP-05 is not intended to _verify_ a user, but only to _identify_ them, for the purpose of facilitating the exchange of a contact or their search.
Exceptions are people who own (e.g., a company) or are connected (e.g., a project) to a well-known domain, who can exploit NIP-05 as an attestation of their relationship with it, and thus to the organization behind it, thereby gaining an element of trust.
### User discovery implementation suggestion
A client can use this to allow users to search other profiles. If a client has a search box or something like that, a user may be able to type "bob@example.com" there and the client would recognize that and do the proper queries to obtain a pubkey and suggest that to the user.
### Clients must always follow public keys, not NIP-05 addresses ### Clients must always follow public keys, not NIP-05 addresses
For example, if after finding that `bob@bob.com` has the public key `abc...def`, the user clicks a button to follow that profile, the client must keep a primary reference to `abc...def`, not `bob@bob.com`. If, for any reason, the address `https://bob.com/.well-known/nostr.json?name=bob` starts returning the public key `1d2...e3f` at any time in the future, the client must not replace `abc...def` in his list of followed profiles for the user (but it should stop displaying "bob@bob.com" for that user, as that will have become an invalid `"nip05"` property).

Clients MAY 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 request reason, not the original content.
A client MUST validate that each event `pubkey` referenced in the `e` tag of the deletion request is identical to the deletion request `pubkey`, before hiding or deleting any event. Relays can not, in general, perform this validation and should not be treated as authoritative. A client MUST validate that each event `pubkey` referenced in the `e` tag of the deletion request is identical to the deletion request `pubkey`, before hiding or deleting any event. Relays can not, in general, perform this validation and should not be treated as authoritative.
Clients display the deletion event itself in any way they choose, e.g., not at all, or with a prominent notice. Clients display the deletion request event itself in any way they choose, e.g., not at all, or with a prominent notice.
Clients MAY choose to inform the user that their request for deletion does not guarantee deletion because it is impossible to delete events from all relays and clients.
## Relay Usage ## Relay Usage
Relays MAY validate that a deletion event only references events that have the same `pubkey` as the deletion itself, however this is not required since relays may not have knowledge of all referenced events. Relays MAY validate that a deletion request event only references events that have the same `pubkey` as the deletion request itself, however this is not required since relays may not have knowledge of all referenced events.
## Deleting a Deletion ## Deletion Request of a Deletion Request
Publishing a deletion event against a deletion has no effect. Clients and relays are not obliged to support "undelete" functionality. Publishing a deletion request event against a deletion request has no effect. Clients and relays are not obliged to support "unrequest deletion" functionality.

Private Direct Messages
-----------------------
`draft` `optional`
This NIP defines an encrypted direct messaging scheme using [NIP-44](44.md) encryption and [NIP-59](59.md) seals and gift wraps.
## Direct Message Kind
Kind `14` is a chat message. `p` tags identify one or more receivers of the message.
```jsonc
{
"id": "<usual hash>",
  "pubkey": "<sender-pubkey>",
"created_at": "<current-time>",
  "kind": 14,
  "tags": [
    ["p", "<receiver-1-pubkey>", "<relay-url>"],
    ["p", "<receiver-2-pubkey>", "<relay-url>"],
    ["e", "<kind-14-id>", "<relay-url>", "reply"] // if this is a reply
["subject", "<conversation-title>"],
    // rest of tags...
  ],
  "content": "<message-in-plain-text>",
}
```
`.content` MUST be plain text. Fields `id` and `created_at` are required.
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.
```jsonc
{
"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:1059` to clients other than the ones tagged in them.
It's advisable that users choose relays that conform to these practices.
Clients SHOULD guide users to keep `kind:10050` lists small (1-3 relays) and SHOULD spread it to as many relays as viable.
## Benefits & Limitations
This NIP offers the following privacy and security features:
1. **No Metadata Leak**: Participant identities, each message's real date and time, event kinds, and other event tags are all hidden from the public. Senders and receivers cannot be linked with public information alone.
2. **No Public Group Identifiers**: There is no public central queue, channel or otherwise converging identifier to correlate or count all messages in the same group.
3. **No Moderation**: There are no group admins: no invitations or bans.
4. **No Shared Secrets**: No secret must be known to all members that can leak or be mistakenly shared
5. **Fully Recoverable**: Messages can be fully recoverable by any client with the user's private key
6. **Optional Forward Secrecy**: Users and clients can opt-in for "disappearing messages".
7. **Uses Public Relays**: Messages can flow through public relays without loss of privacy. Private relays can increase privacy further, but they are not required.
8. **Cold Storage**: Users can unilaterally opt-in to sharing their messages with a separate key that is exclusive for DM backup and recovery.
The main limitation of this approach is having to send a separate encrypted event to each receiver. Group chats with more than 100 participants should find a more suitable messaging scheme.
## Implementation
Clients implementing this NIP should by default only connect to the set of relays found in their `kind:10050` list. From that they should be able to load all messages both sent and received as well as get new live updates, making it for a very simple and lightweight implementation that should be fast.
When sending a message to anyone, clients must then connect to the relays in the receiver's `kind:10050` and send the events there, but can disconnect right after unless more messages are expected to be sent (e.g. the chat tab is still selected). Clients should also send a copy of their outgoing messages to their own `kind:10050` relay set.
## Examples
This example sends the message `Hola, que tal?` from `nsec1w8udu59ydjvedgs3yv5qccshcj8k05fh3l60k9x57asjrqdpa00qkmr89m` to `nsec12ywtkplvyq5t6twdqwwygavp5lm4fhuang89c943nf2z92eez43szvn4dt`.
The two final GiftWraps, one to the receiver and the other to the sender, are:

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 _addressable_ events signed by the relay keypair directly, with the group _id_ as the `d` tag.
## Group identifier
A group may be identified by a string in the format `<host>'<group-id>`. For example, a group with _id_ `abcdef` hosted at the relay `wss://groups.nostr.com` would be identified by the string `groups.nostr.com'abcdef`.
## 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.
```jsonc
"kind": 11,
"content": "hello my friends lovers of pizza",
"tags": [
["h", "<group-id>"],
["previous", "<event-id-first-chars>", "<event-id-first-chars>", /*...*/]
]
// other fields...
```
- *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.
```jsonc
"kind": 9,
"content": "hello my friends lovers of pizza",
"tags": [
["h", "<group-id>"],
["previous", "<event-id-first-chars>", "<event-id-first-chars>", /*...*/]
]
// other fields...
```
- *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.
```json
{
"kind": 9021,
"content": "optional reason",
"tags": [
["h", "<group-id>"]
]
}
```
- *leave request* (`kind:9022`)
Any user can send one of these events to the relay in order to be automatically removed from the group. The relay will automatically issue a `kind:9001` in response removing this user.
```json
{
"kind": 9022,
"content": "optional reason",
"tags": [
["h", "<group-id>"]
]
}
```
- *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.
```json
{
"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` | |
| 9008 | `delete-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.
```jsonc
{
"kind": 39000,
"content": "",
"tags": [
["d", "<group-id>"],
["name", "Pizza Lovers"],
["picture", "https://pizza.com/pizza.png"],
["about", "a group for people who love pizza"],
["public"], // or ["private"]
["open"] // or ["closed"]
]
// other fields...
}
```
`name`, `picture` and `about` are basic metadata for the group for display purposes. `public` signals the group can be _read_ by anyone, while `private` signals that only AUTHed users can read. `open` signals that anyone can request to join and the request will be automatically granted, while `closed` signals that members must be pre-approved or that requests to join will be manually handled.
- *group admins* (`kind:39001`) (optional)
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`
- `delete-group`
```json
{
"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"]
]
// other fields...
}
```
- *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.

NIP-34
======
`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.
## Repository state announcements
An optional source of truth for the state of branches and tags in a repository.
```jsonc
{
"kind": 30618,
"content": "",
"tags": [
["d", "<repo-id>"], // matches the identifier in the coresponding repository announcement
["refs/<heads|tags>/<branch-or-tag-name>","<commit-id>"]
["HEAD", "ref: refs/heads/<branch-name>"]
]
}
```
The `refs` tag may appear multiple times, or none.
If no `refs` tags are present, the author is no longer tracking repository state using this event. This approach enables the author to restart tracking state at a later time unlike [NIP-09](09.md) deletion requests.
The `refs` tag can be optionally extended to enable clients to identify how many commits ahead a ref is:
```jsonc
{
"tags": [
["refs/<heads|tags>/<branch-or-tag-name>", "<commit-id>", "<shorthand-parent-commit-id>", "<shorthand-grandparent>", ...],
]
}
```
## Patches
Patches can be sent by anyone to any repository. Patches to a specific repository SHOULD be sent to the relays specified in that repository's announcement event's `"relays"` tag. Patch events SHOULD include an `a` tag pointing to that repository's announcement address.
Patches in a patch set SHOULD include a NIP-10 `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"], // omitted for additional patches in a series
// for the first patch in a revision
["t", "root-revision"],
// optional tags for when it is desirable that the merged patch has a stable commit id
// these fields are necessary for ensuring that the commit resulting from applying a patch
// has the same id as it had in the proposer's machine -- all these tags can be omitted
// if the maintainer doesn't care about these things
["commit", "<current-commit-id>"],
["r", "<current-commit-id>"] // so clients can find existing patches for a specific commit
["parent-commit", "<parent-commit-id>"],
["commit-pgp-sig", "-----BEGIN PGP SIGNATURE-----..."], // empty string for unsigned commit
["committer", "<name>", "<email>", "<timestamp>", "<timezone offset in minutes>"],
]
}
```
The first patch in a series MAY be a cover letter in the format produced by `git format-patch`.
## Issues
Issues are Markdown text that is just human-readable conversational threads related to the repository: bug reports, feature requests, questions or comments of any kind. Like patches, these SHOULD be sent to the relays specified in that repository's announcement event's `"relays"` tag.
```json
{
"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"],
// rest of tags...
],
// other fields...
}
```
## 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.
## Possible things to be added later
- "branch merge" kind (specifying a URL from where to fetch the branch to be merged)
- 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.
```json
{
"kind": 2003,
"content": "<long-description-pre-formatted>",
"tags": [
["title", "<torrent-title>"],
["x", "<bittorrent-info-hash>"],
["file", "<file-name>", "<file-size-in-bytes>"],
["file", "<file-name>", "<file-size-in-bytes>"],
["tracker", "udp://mytacker.com:1337"],
["tracker", "http://1337-tracker.net/announce"],

["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.

Nostr Connect Nostr Remote Signing
------------- --------------------
`draft` `optional` ## Rationale
This NIP describes a method for 2-way communication between a **remote signer** and a normal Nostr client. The remote signer could be, for example, a hardware device dedicated to signing Nostr events, while the client is a normal Nostr client. Private keys should be exposed to as few systems - apps, operating systems, devices - as possible as each system adds to the attack surface.
## Signer Discovery This NIP describes a method for 2-way communication between a remote signer and a Nostr client. The remote signer could be, for example, a hardware device dedicated to signing Nostr events, while the client is a normal Nostr client.
The client always starts by generating a random key which is used to communicate with the signer, then it one of the methods below is used to allow the client to know what is the signer public key for the session and which relays to use. ## Terminology
### Started by the signer (nsecBunker) - **Local keypair**: A local public and private key-pair used to encrypt content and communicate with the remote signer. Usually created by the client application.
- **Remote user pubkey**: The public key that the user wants to sign as. The remote signer has control of the private key that matches this public key.
- **Remote signer pubkey**: This is the public key of the remote signer itself. This is needed in both `create_account` command because you don't yet have a remote user pubkey.
The remote signer generates a connection token in the form All pubkeys specified in this NIP are in hex format.
## Initiating a connection
To initiate a connection between a client and a remote signer there are a few different options.
### Direct connection initiated by remote signer
This is most common in a situation where you have your own nsecbunker or other type of remote signer and want to connect through a client that supports remote signing.
The remote signer would provide a connection token in the form:
``` ```
bunker://<hex-pubkey>?relay=wss://...&relay=wss://...&secret=<optional-secret> bunker://<remote-user-pubkey>?relay=<wss://relay-to-connect-on>&relay=<wss://another-relay-to-connect-on>&secret=<optional-secret-value>
``` ```
The user copies that token and pastes it in the client UI somehow. Then the client can send events of kind `24133` to the specified relays and wait for responses from the remote signer. This token is pasted into the client by the user and the client then uses the details to connect to the remote signer via the specified relay(s). Optional secret can be used for single successfully established connection only, remote signer SHOULD ignore new attempts to establish connection with old optional secret.
### Started by the client ### Direct connection initiated by the client
The client generates a QR code in the following form (URL-encoded): In this case, basically the opposite direction of the first case, the client provides a connection token (or encodes the token in a QR code) and the signer initiates a connection to the client via the specified relay(s).
``` ```
nostrconnect://<client-key-hex>?relay=wss://...&metadata={"name":"...", "url": "...", "description": "..."} nostrconnect://<local-keypair-pubkey>?relay=<wss://relay-to-connect-on>&metadata=<json metadata in the form: {"name":"...", "url": "...", "description": "..."}>
``` ```
The signer scans the QR code and sends a `connect` message to the client in the specified relays. ## The flow
## Event payloads 1. Client creates a local keypair. This keypair doesn't need to be communicated to the user since it's largely disposable (i.e. the user doesn't need to see this pubkey). Clients might choose to store it locally and they should delete it when the user logs out.
2. Client gets the remote user pubkey (either via a `bunker://` connection string or a NIP-05 login-flow; shown below)
3. Clients use the local keypair to send requests to the remote signer by `p`-tagging and encrypting to the remote user pubkey.
4. The remote signer responds to the client by `p`-tagging and encrypting to the local keypair pubkey.
Event payloads are [NIP-04](04.md)-encrypted JSON blobs that look like JSONRPC messages (their format is specified inside the `.content` of the event formats below). ### Example flow for signing an event
Events sent by the client to the remote signer have the following format: - Remote user pubkey (e.g. signing as) `fa984bd7dbb282f07e16e7ae87b26a2a7b9b90b7246a44771f0cf5ae58018f52`
- Local pubkey is `eff37350d839ce3707332348af4549a96051bd695d3223af4aabce4993531d86`
```js #### Signature request
```json
{ {
"pubkey": "<client-key-hex>"
"kind": 24133, "kind": 24133,
"tags": [ "pubkey": "eff37350d839ce3707332348af4549a96051bd695d3223af4aabce4993531d86",
["p", "<signer-key-hex>"] "content": nip04({
], "id": <random_string>,
"content": "nip04_encrypted_json({id: <random-string>, method: <see-below>, params: [array_of_strings]})", "method": "sign_event",
... "params": [json_stringified(<{
content: "Hello, I'm signing remotely",
kind: 1,
tags: [],
created_at: 1714078911
}>)]
}),
"tags": [["p", "fa984bd7dbb282f07e16e7ae87b26a2a7b9b90b7246a44771f0cf5ae58018f52"]], // p-tags the remote user pubkey
} }
``` ```
And the events the remote signer sends to the client have the following format: #### Response event
```js ```json
"pubkey": "<signer-key-hex>" {
"kind": 24133, "kind": 24133,
"tags": [ "pubkey": "fa984bd7dbb282f07e16e7ae87b26a2a7b9b90b7246a44771f0cf5ae58018f52",
["p", "<client-key-hex>"] "content": nip04({
], "id": <random_string>,
"content": "nip04_encrypted_json({id: <request-id>, result: <string>, error: <reason-string>})", "result": json_stringified(<signed-event>)
... }),
"tags": [["p", "eff37350d839ce3707332348af4549a96051bd695d3223af4aabce4993531d86"]], // p-tags the local keypair pubkey
}
``` ```
The signer key will always be the key of the user who controls the signer device. #### Diagram

- **connect** ## Request Events `kind: 24133`
- params: [`pubkey`, `secret`]
- result: `"ack"` ```jsonc
- **get_public_key** {
- params: [] "id": <id>,
- result: `pubkey-hex` "kind": 24133,
- **sign_event** "pubkey": <local_keypair_pubkey>,
- params: [`event`] "content": <nip04(<request>)>,
- result: `json_string(event_with_pubkey_id_and_signature)` "tags": [["p", <remote_user_pubkey>]], // NB: in the `create_account` event, the remote signer pubkey should be `p` tagged.
- **get_relays** "created_at": <unix timestamp in seconds>
- params: [] }
- result: `json_string({[url: string]: {read: boolean, write: boolean}})` ```
- **nip04_encrypt**
- params: [`third-party-pubkey`, `plaintext`] The `content` field is a JSON-RPC-like message that is [NIP-04](04.md) encrypted and has the following structure:
- result: `nip04-ciphertext`
- **nip04_decrypt** ```json
- params: [`third-party-pubkey`, `nip04-ciphertext`] {
- result: `plaintext` "id": <random_string>,
- **nip44_get_key** "method": <method_name>,
- params: [`third-party-pubkey`] "params": [array_of_strings]
- result: `nip44-conversation-key` }
- **nip44_encrypt** ```
- params: [`third-party-pubkey`, `plaintext`]
- result: `nip44-ciphertext` - `id` is a random string that is a request ID. This same ID will be sent back in the response payload.
- **nip44_decrypt** - `method` is the name of the method/command (detailed below).
- params: [`third-party-pubkey`, `nip44-ciphertext`] - `params` is a positional array of string parameters.
- result: `plaintext`
- **ping** ### Methods/Commands
- params: []
- result: `"pong"` Each of the following are methods that the client sends to the remote signer.
| Command | Params | Result |
| ------------------------ | ------------------------------------------------- | ---------------------------------------------------------------------- |
| `connect` | `[<remote_user_pubkey>, <optional_secret>, <optional_requested_permissions>]` | "ack" |
| `sign_event` | `[<{kind, content, tags, created_at}>]` | `json_stringified(<signed_event>)` |
| `ping` | `[]` | "pong" |
| `get_relays` | `[]` | `json_stringified({<relay_url>: {read: <boolean>, write: <boolean>}})` |
| `get_public_key` | `[]` | `<hex-pubkey>` |
| `nip04_encrypt` | `[<third_party_pubkey>, <plaintext_to_encrypt>]` | `<nip04_ciphertext>` |
| `nip04_decrypt` | `[<third_party_pubkey>, <nip04_ciphertext_to_decrypt>]` | `<plaintext>` |
| `nip44_encrypt` | `[<third_party_pubkey>, <plaintext_to_encrypt>]` | `<nip44_ciphertext>` |
| `nip44_decrypt` | `[<third_party_pubkey>, <nip44_ciphertext_to_decrypt>]` | `<plaintext>` |
### Requested permissions
The `connect` method may be provided with `optional_requested_permissions` for user convenience. The permissions are a comma-separated list of `method[:params]`, i.e. `nip04_encrypt,sign_event:4` meaning permissions to call `nip04_encrypt` and to call `sign_event` with `kind:4`. Optional parameter for `sign_event` is the kind number, parameters for other methods are to be defined later.
## Response Events `kind:24133`
```json
{
"id": <id>,
"kind": 24133,
"pubkey": <remote_signer_pubkey>,
"content": <nip04(<response>)>,
"tags": [["p", <local_keypair_pubkey>]],
"created_at": <unix timestamp in seconds>
}
```
The `content` field is a JSON-RPC-like message that is [NIP-04](04.md) encrypted and has the following structure:
```json
{
"id": <request_id>,
"result": <results_string>,
"error": <optional_error_string>
}
```
- `id` is the request ID that this response is for.
- `results` is a string of the result of the call (this can be either a string or a JSON stringified object)
- `error`, _optionally_, it is an error in string form, if any. Its presence indicates an error with the request.
### Auth Challenges
An Auth Challenge is a response that a remote signer can send back when it needs the user to authenticate via other means. This is currently used in the OAuth-like flow enabled by signers like [Nsecbunker](https://github.com/kind-0/nsecbunkerd/). The response `content` object will take the following form:
```json
{
"id": <request_id>,
"result": "auth_url",
"error": <URL_to_display_to_end_user>
}
```
Clients should display (in a popup or new tab) the URL from the `error` field and then subscribe/listen for another response from the remote signer (reusing the same request ID). This event will be sent once the user authenticates in the other window (or will never arrive if the user doesn't authenticate). It's also possible to add a `redirect_uri` url parameter to the auth_url, which is helpful in situations when a client cannot open a new window or tab to display the auth challenge.
#### Example event signing request with auth challenge
![signing-example-with-auth-challenge](https://i.nostr.build/W3aj.png)
## Remote Signer Commands
Remote signers might support additional commands when communicating directly with it. These commands follow the same flow as noted above, the only difference is that when the client sends a request event, the `p`-tag is the pubkey of the remote signer itself and the `content` payload is encrypted to the same remote signer pubkey.
### Methods/Commands
Each of the following are methods that the client sends to the remote signer.
| Command | Params | Result |
| ---------------- | ------------------------------------------ | ------------------------------------ |
| `create_account` | `[<username>, <domain>, <optional_email>, <optional_requested_permissions>]` | `<newly_created_remote_user_pubkey>` |
## Appendix
### NIP-05 Login Flow
Clients might choose to present a more familiar login flow, so users can type a NIP-05 address instead of a `bunker://` string.
When the user types a NIP-05 the client:
- Queries the `/.well-known/nostr.json` file from the domain for the NIP-05 address provided to get the user's pubkey (this is the **remote user pubkey**)
- In the same `/.well-known/nostr.json` file, queries for the `nip46` key to get the relays that the remote signer will be listening on.
- Now the client has enough information to send commands to the remote signer on behalf of the user.
### OAuth-like Flow
#### Remote signer discovery via NIP-89
In this last case, most often used to facilitate an OAuth-like signin flow, the client first looks for remote signers that have announced themselves via NIP-89 application handler events.
First the client will query for `kind: 31990` events that have a `k` tag of `24133`.
These are generally shown to a user, and once the user selects which remote signer to use and provides the remote user pubkey they want to use (via npub, pubkey, or nip-05 value), the client can initiate a connection. Note that it's on the user to select the remote signer that is actually managing the remote key that they would like to use in this case. If the remote user pubkey is managed on another remote signer, the connection will fail.
In addition, it's important that clients validate that the pubkey of the announced remote signer matches the pubkey of the `_` entry in the `/.well-known/nostr.json` file of the remote signer's announced domain.
Clients that allow users to create new accounts should also consider validating the availability of a given username in the namespace of remote signer's domain by checking the `/.well-known/nostr.json` file for existing usernames. Clients can then show users feedback in the UI before sending a `create_account` event to the remote signer and receiving an error in return. Ideally, remote signers would also respond with understandable error messages if a client tries to create an account with an existing username.

NIP-54
======
Wiki
----
`draft` `optional`
This NIP defines `kind:30818` (an _addressable event_) for descriptions (or encyclopedia entries) of particular subjects, and it's expected that multiple people will write articles about the exact same subjects, with either small variations or completely independent content.
Articles are identified by lowercase, normalized ascii `d` tags.
### Articles
```json
{
"content": "A wiki is a hypertext publication collaboratively edited and managed by its own audience.",
"tags": [
["d", "wiki"],
["title", "Wiki"],
]
}
```
### `d` tag normalization rules
- Any non-letter character MUST be converted to a `-`.
- All letters MUST be converted to lowercase.
### Content
The `content` should be Asciidoc with two extra functionalities: **wikilinks** and **nostr:...** links.
Unlike normal Asciidoc links `http://example.com[]` that link to external webpages, wikilinks `[[]]` link to other articles in the wiki. In this case, the wiki is the entirety of Nostr. Clicking on a wikilink should cause the client to ask relays for events with `d` tags equal to the target of that wikilink.
Wikilinks can take these two forms:
1. `[[Target Page]]` -- in this case it will link to the page `target-page` (according to `d` tag normalization rules above) and be displayed as `Target Page`;
2. `[[target page|see this]]` -- in this case it will link to the page `target-page`, but will be displayed as `see this`.
`nostr:...` links, as per [NIP-21](21.md), should link to profiles or arbitrary Nostr events. Although it is not recommended to link to specific versions of articles -- instead the _wikilink_ syntax should be preferred, since it should be left to the reader and their client to decide what version of any given article they want to read.
### Optional extra tags
- `title`: for when the display title should be different from the `d` tag.
- `summary`: for display in lists.
- `a` and `e`: for referencing the original event a wiki article was forked from.
### Merge Requests
Event `kind:818` represents a request to merge from a forked article into the source. It is directed to a pubkey and references the original article and the modified event.
[INSERT EVENT EXAMPLE]
### Redirects
Event `kind:30819` is also defined to stand for "wiki redirects", i.e. if one thinks `Shell structure` should redirect to `Thin-shell structure` they can issue one of these events instead of replicating the content. These events can be used for automatically redirecting between articles on a client, but also for generating crowdsourced "disambiguation" pages ([common in Wikipedia](https://en.wikipedia.org/wiki/Help:Disambiguation)).
[INSERT EVENT EXAMPLE]
How to decide what article to display
-------------------------------------
As there could be many articles for each given name, some kind of prioritization must be done by clients. Criteria for this should vary between users and clients, but some means that can be used are described below:
### Reactions
[NIP-25](25.md) reactions are very simple and can be used to create a simple web-of-trust between wiki article writers and their content. While just counting a raw number of "likes" is unproductive, reacting to any wiki article event with a `+` can be interpreted as a recommendation for that article specifically and a partial recommendation of the author of that article. When 2 or 3-level deep recommendations are followed, suddenly a big part of all the articles may have some form of tagging.
### Relays
[NIP-51](51.md) lists of relays can be created with the kind 10102 and then used by wiki clients in order to determine where to query articles first and to rank these differently in relation to other events fetched from other relays.
### Contact lists
[NIP-02](02.md) contact lists can form the basis of a recommendation system that is then expanded with relay lists and reaction lists through nested queries. These lists form a good starting point only because they are so widespread.
### Wiki-related contact lists
[NIP-51](51.md) lists can also be used to create a list of users that are trusted only in the context of wiki authorship or wiki curationship.
Forks
---------
Wiki-events can tag other wiki-events with a `fork` marker to specify that this event came from a different version. Both `a` and `e` tags SHOULD be used and have the `fork` marker applied, to identify the exact version it was forked from.
Deference
---------
Wiki-events can tag other wiki-events with a `defer` marker to indicate that it considers someone else's entry as a "better" version of itself. If using a `defer` marker both `a` and `e` tags SHOULD be used.
This is a stronger signal of trust than a `+` reaction.
This marker is useful when a user edits someone else's entry; if the original author includes the editor's changes and the editor doesn't want to keep/maintain an independent version, the `link` tag could effectively be a considered a "deletion" of the editor's version and putting that pubkey's WoT weight behind the original author's version.
Why Asciidoc?
-------------
Wikitext is [garbage](nostr:nevent1qqsqt0gcggry60n72uglhuhypdlmr2dm6swjj69jex5v530gcpazlzsprpmhxue69uhhyetvv9ujumn0wdmksetjv5hxxmmdqy28wumn8ghj7un9d3shjtnyv9kh2uewd9hsygpm7rrrljungc6q0tuh5hj7ue863q73qlheu4vywtzwhx42a7j9n5ueneex) and Markdown is not powerful enough (besides being too freeform and unspecified and prone to generate incompatibilities in the future).
Asciidoc has a strict spec, multiple implementations in many languages, and support for features that are very much necessary in a wiki article, like _sidebars_, _tables_ (with rich markup inside cells), many levels of _headings_, _footnotes_, _superscript_ and _subscript_ markup and _description lists_. It is also arguably easier to read in its plaintext format than Markdown (and certainly much better than Wikitext).
# Appendix 1: Merge requests
Users can request other users to get their entries merged into someone else's entry by creating a `kind:818` event.

======
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")
```

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")

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:

// the id you sent
val id = intent.data?.getStringExtra("id")
```

```
- result:
- If the user approved intent it will return the **signature** and **id** fields
```kotlin

- If the user approved intent it will return the **signature** and **id** fields
```kotlin
val eventJson = intent.data?.getStringExtra("signature")
// the id you sent
val id = intent.data?.getStringExtra("id")
```
## 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
### Methods

```
# 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

Chess (Portable Game Notation)
------------------------------
`draft` `optional`
This NIP defines `kind:64` notes representing chess games in [PGN][pgn_specification] format, which can be read by humans and is also supported by most chess software.
## Note
### Content
The `.content` of these notes is a string representing a [PGN-database][pgn_formal_syntax].
### Notes
```jsonc
{
"kind": 64,
"content": "1. e4 *",
// other fields...
}
```
```jsonc

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

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

```
## 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.

NIP-71
======
Video Events
------------
`draft` `optional`
This specification defines video events representing a dedicated post of externally hosted content. These video events are _addressable_ and delete-requestable 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
```jsonc

// Hashtags
["t", "<tag>"],
["t", "<tag>"],
// Reference links
["r", "<url>"],
["r", "<url>"]
]
}
```
## 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>,

"content": "<note>",

["d", "<34235 | 34236>:<video event author pubkey>:<d-identifier of video event>"],
["viewed", <start>, <end>],
]
}

# Post Approval by moderators 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.
The post-approval event MUST include `a` tags of the communities the moderator is posting into (one or more), the `e` tag of the post and `p` tag of the author of the post (for approval notifications). The event SHOULD also include the stringified `post request` event inside the `.content` ([NIP-18-style](18.md)) and a `k` tag with the original post's event kind to allow filtering of approved posts by kind. An approval event MUST include one or more community `a` tags, an `e` or `a` tag pointing to the post, and the `p` tag of the author of the post (for approval notifications). `a` tag prefixes can be used to disambiguate between community and replaceable event pointers (community `a` tags always begin with `34550`).
The event SHOULD also include the JSON-stringified `post request` event inside the `.content`, and a `k` tag with the original post's event kind to allow filtering of approved posts by kind.

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.

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. Approvals of replaceable events can be created in three ways:
Clients SHOULD evaluate any non-`34550:*` `a` tag as posts to be included in all `34550:*` `a` tags. 1. By tagging the replaceable event as an `e` tag if moderators want to approve each individual change to the replaceable event
2. By tagging the replaceable event as an `a` tag if the moderator authorizes the replaceable event author to make changes without additional approvals and
3. 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.
# Displaying Since relays are instructed to delete old versions of a replaceable event, the `content` of an approval using an `e` tag MUST have the specific version of the event or clients might not be able to find that version of the content anywhere.
Community clients SHOULD display posts that have been approved by at least 1 moderator or by the community owner. Clients SHOULD evaluate any non-`34550:*` `a` tag as posts to be approved for all `34550:*` `a` tags.
The following filter displays the approved posts. # Cross-posting
```json Clients MAY support cross-posting between communities by posting a NIP 18 `kind 6` or `kind 16` repost to one or more communities using `a` tags as described above. The `content` of the repost MUST be the original event, not the approval event.

NIP-73
======
External Content IDs
--------------------
`draft` `optional`
There are certain established global content identifiers that would be useful to reference in nostr events so that clients can query all events assosiated with these ids.
- Book [ISBNs](https://en.wikipedia.org/wiki/ISBN)
- Podcast [GUIDs](https://podcastnamespace.org/tag/guid)
- Movie [ISANs](https://en.wikipedia.org/wiki/International_Standard_Audiovisual_Number)
Since the `i` tag is already used for similar references in kind-0 metadata events it makes sense to use it for these content ids as well.
## Supported IDs
### Books:
- Book ISBN: `["i", "isbn:9780765382030"]` - https://isbnsearch.org/isbn/9780765382030
Book ISBNs MUST be referenced _**without hyphens**_ as many book search APIs return the ISBNs without hyphens. Removing hypens from ISBNs is trivial, whereas adding the hyphens back in is non-trivial requiring a library.
### Podcasts:
- Podcast RSS Feed GUID: `["i", "podcast:guid:c90e609a-df1e-596a-bd5e-57bcc8aad6cc"]` - https://podcastindex.org/podcast/c90e609a-df1e-596a-bd5e-57bcc8aad6cc
- Podcast RSS Item GUID: `["i", "podcast:item:guid:d98d189b-dc7b-45b1-8720-d4b98690f31f"]`
- Podcast RSS Publisher GUID: `["i", "podcast:publisher:guid:18bcbf10-6701-4ffb-b255-bc057390d738"]`
### Movies:
- Movie ISAN: `["i", "isan:0000-0000-401A-0000-7"]` - https://web.isan.org/public/en/isan/0000-0000-401A-0000-7
Movie ISANs SHOULD be referenced _**without the version part**_ as the versions / edits of movies are not relevant. More info on ISAN parts here - https://support.isan.org/hc/en-us/articles/360002783131-Records-relations-and-hierarchies-in-the-ISAN-Registry
---
### Optional URL Hints
Each `i` tag MAY have a url hint as the second argument to redirect people to a website if the client isn't opinionated about how to interpret the id:
`["i", "podcast:item:guid:d98d189b-dc7b-45b1-8720-d4b98690f31f", https://fountain.fm/episode/z1y9TMQRuqXl2awyrQxg]`

## Upload ## 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). **AUTH required**
If using an html form, use an `Authorization` form data field instead.
These following **optional** form data fields MAY be used by `servers` and SHOULD be sent by `clients`: List of form fields:
- `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; - `file`: **REQUIRED** the file to upload
- `alt`: (recommended) strict description text for visibility-impaired users; - `caption`: **RECOMMENDED** loose description;
- `caption`: loose description; - `expiration`: UNIX timestamp in seconds. Empty string if file should be stored forever. The server isn't required to honor this.
- `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; - `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. - `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. Others custom form data fields may be used depending on specific `server` support.
The `server` isn't required to store any metadata sent by `clients`. The `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 `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. The `server` MUST link the user's `pubkey` string 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` 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. - `200 OK`: File upload exists, but is successful (Existing hash)
- `201 Created`: File upload successful (New hash)
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. - `202 Accepted`: File upload is awaiting processing, see [Delayed Processing](#delayed-processing) section
- `413 Payload Too Large`: File size exceeds limit
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.). - `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.
On successful uploads the `server` MUST reply with **201 Created** HTTP status code or **202 Accepted** if a `processing_url` field is added - `402 Payment Required`: Payment is required by the server, **this flow is undefined**.
