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.

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.

## Calendar Events
There are two types of calendar events represented by different kinds: date-based and time-based calendar events. Calendar events are not required to be part of a [calendar](#calendar).
There are two types of calendar events represented by different kinds: _date-based_ and _time-based_ calendar events.
### Date-Based Calendar Event
These tags are common to both types of calendar events:
This kind of calendar event starts on a date and ends before a different date in the future. Its use is appropriate for all-day or multi-day events where time and time zone hold no significance. e.g., anniversary, public holidays, vacation days.
#### Format
The format uses an _addressable event_ of `kind:31922`.
The `.content` of these events should be a detailed description of the calendar event. It is required but can be an empty string.
The list of tags are as follows:
* `d` (required) universally unique identifier (UUID). Generated by the client creating the calendar event.
* `d` (required) a short unique string identifier. Generated by the client creating the calendar event.
* `title` (required) title of the calendar event
* `start` (required) inclusive start date in ISO 8601 format (YYYY-MM-DD). Must be less than `end`, if it exists.
* `end` (optional) exclusive end date in ISO 8601 format (YYYY-MM-DD). If omitted, the calendar event ends on the same date as `start`.
* `summary` (optional) brief description of the calendar event
* `image` (optional) url of an image to use for the event
* `location` (optional, repeated) location of the calendar event. e.g. address, GPS coordinates, meeting room name, link to video call

Calendar events are _not_ required to be part of a [calendar](#calendar).
### Date-Based Calendar Event
This kind of calendar event starts on a date and ends before a different date in the future. Its use is appropriate for all-day or multi-day events where time and time zone hold no significance. e.g., anniversary, public holidays, vacation days.
It's an _addressable event_ of `kind:31922`.
The `.content` of these events SHOULD be a description of the calendar event.
Aside from the common tags, this also takes the following tags:
* `start` (required) inclusive start date in ISO 8601 format (YYYY-MM-DD). Must be less than `end`, if it exists.
* `end` (optional) exclusive end date in ISO 8601 format (YYYY-MM-DD). If omitted, the calendar event ends on the same date as `start`.

## Calendar
A calendar is a collection of calendar events, represented as a custom replaceable list event using kind `31924`. A user can have multiple calendars. One may create a calendar to segment calendar events for specific purposes. e.g., personal, work, travel, meetups, and conferences.

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

NIP-66
======
Relay Discovery and Liveness Monitoring
-------------------
`draft` `optional`
You want to find relays. You may want to discover relays based on criteria that's up to date. You may even want to ensure that you have a complete dataset. You probably want to filter relays based on their reported liveness.
In its purest form:
```json
{
"kind": 30166,
"created_at": 1722173222,
"content": "{}",
"tags": [
[ "d", "wss://somerelay.abc/" ]
],
"pubkey": "<pubkey>",
"sig": "<signature>",
"id": "<eventid>"
}
```
This event signals that the relay at `wss://somerelay.abc/` was reported "online" by `<pubkey>` at timestamp `1722173222`. This event **MAY** be extended upon to include more information.
## Kinds
`NIP-66` defines two (2) event kinds, `30166` and `10166`
| kind | name | description |
|-------|----------------------------|-----------------------------------------------------------------------------------------|
| [30166](#k30166) | Relay Discovery | An addressable event that is published by a monitor when a relay is online |
| [10166](#k10166) | Relay Monitor Announcement | An RE that stores data that signals the intent of a pubkey to monitor relays and publish `30166` events at a regular _frequency_ |
## Ontology
- `Relay Operator`: someone who operates a relay
- `Monitor`: A pubkey that monitors relays and publishes `30166` events at the frequency specified in their `10166` event.
- `Ad-hoc Monitor`: A pubkey that monitors relays and publishes `30166` events at an irregular frequency.
- `Monitor Service`: A group or individual that monitors relays using one or more `Monitors`.
- `Check`: a specific data point that is tested or aggregated by a monitor.
## `30166`: "Relay Discovery" <a id="k30166"></a>
### Summary
`30166` is a `NIP-33` addressable event, referred to as a "Relay Discovery" event. These events are optimized with a small footprint for protocol-level relay Discovery.
### Purpose
Discovery of relays over nostr.
### Schema
#### Content
`30166` content fields **SHOULD** include the stringified JSON of the relay's NIP-11 informational document. This data **MAY** be provided for informational purposes only.
#### `created_at`
The `created_at` field in a NIP-66 event should reflect the time when the relay liveness (and potentially other data points) was checked.
#### `tags`
##### Meta Tags (unindexed)
- `rtt-open` The relay's open **round-trip time** in milliseconds.
- `rtt-read` The relay's read **round-trip time** in milliseconds.
- `rtt-write` The relay's write **round-trip time** in milliseconds.
_Other `rtt` values **MAY** be present. This NIP should be updated if there is value found in more `rtt` values._
##### Single Letter Tags (indexed)
- `d` The relay URL/URI. The `#d` tag **must** be included in the `event.tags[]` array. Index position `1` **must** be the relay websocket URL/URI. If a URL it **SHOULD** be [normalized](https://datatracker.ietf.org/doc/html/rfc3986#section-6). For relays not accessible via conventional means but rather by an npub/pubkey, an npub/pubkey **MAY** be used in place of a URL.
```json
[ "d", "wss://somerelay.abc/"]
```
- `n`: Network
```json
[ "n", "clearnet" ]
```
- `T`: Relay Type. Enumerated [relay type](https://github.com/nostr-protocol/nips/issues/1282) formatted as `PascalCase`
```json
["T", "PrivateInbox" ]
```
- `N`: Supported Nips _From NIP-11 "Informational Document" `nip11.supported_nips[]`_
```json
[ "N", "42" ]
```
- `R`: Requirements _NIP-11 "Informational Document" `nip11.limitations.payment_required`, `nip11.limitations.auth_required` and/or any other boolean value within `nip11.limitations[]` that is added in the future_
```json
[ "R", "payment" ],
[ "R", "auth" ],
```
Since the nostr protocol does not currently support filtering on whether an indexed tag **is** or **is not** set, to make "public" and "no auth" relays discoverable requires a `!` flag
```json
[ "R", "!payment" ], //no payment required, is public
[ "R", "!auth" ], //no authentication required
```
- `t`: "Topics" _From NIP-11 "Informational Document" `nip11.tags[]`_
```json
[ "t", "nsfw" ]
```
- `k`: Accepted/Blocked Kinds [`NIP-22`]
```json
[ "k", "0" ],
[ "k", "3" ],
[ "k", "10002" ]
```
or for blocked kinds
```json
[ "k", "!0" ]
[ "k", "!3" ],
[ "k", "!10002" ]
```
- `g`: `NIP-52` `g` tags (geohash)
```json
[ "g", "9r1652whz" ]
```
- `30166` **MAY** be extended with global tags defined by other NIPs that do no collide with locally defined indices, including but not limited to: `p`, `t`, `e`, `a`, `i` and `l/L`.
#### Robust Example of a `30166` Event
_Relay was online, and you can filter on a number of different tags_

}
```
## `10166`: "Relay Monitor Announcement" Events <a id="k10166"></a>
### Summary
`10166` is a replacable event herein referred to as "Relay Monitor Announcement" events. These events contain information about a publisher's intent to monitor and publish data as `30166` events. This event is optional and is intended for monitors who intend to provide monitoring services at a regular and predictable frequency.
### Purpose
To provide a directory of monitors, their intent to publish, their criteria and parameters of monitoring activities. Absence of this event implies the monitor is ad-hoc and does not publish events at a predictable frequency, and relies on mechanisms to infer data integrity, such as web-of-trust.
### Schema
#### Standard Tags
- `frequency` The frequency **in seconds** at which the monitor publishes events. A string-integer at index `1` represents the expected frequency the monitor will publish `30166` events. There should only be `1` frequency per monitor.
```json
[ "frequency", "3600" ]
```
- `timeout` (optional) The timeout values for various checks conducted by a monitor. Index `1` is the monitor's timeout in milliseconds. Index `2` describes what test the timeout is used for. If no index `2` is provided, it is inferred that the timeout provided applies to all tests. These values can assist relay operators in understanding data signaled by the monitor in _Relay Discovery Events_.
```json
[ "timeout", "2000", "open" ],
[ "timeout", "2000", "read" ],
[ "timeout", "3000", "write" ],
[ "timeout", "2000", "nip11" ],
[ "timeout", "4000", "ssl" ]
```
#### Indexed Tags
- `c` "Checks" **SHOULD** be a lowercase string describing the check(s) conducted by a monitor. Due to the rapidly evolving nature of relays, enumeration is organic and not strictly defined. But examples of some checks could be websocket `open/read/write/auth`, `nip11` checks, `dns` and `geo` checks, and and any other checks the monitor may deem useful.. Other checks **MAY** be included. New types of checks **SHOULD** be added to this NIP as they are needed.
```json
[ "c", "ws" ],
[ "c", "nip11" ],
[ "c", "dns" ],
[ "c", "geo" ],
[ "c", "ssl" ],
```
- `g`: `NIP-52` `g` tags (geohash)
```json
[ "g", "9r1652whz" ]
```
- Any other globally defined indexable tags **MAY** be included as found necessary.
### Other Requirements
Monitors **SHOULD** have the following
- A published `0` (NIP-1) event
- A published `10002` (NIP-65) event that defines the relays the monitor publishes to.
### Robust Example of a `10166` Event

## Methodology
### Monitors
1. A _Relay Monitor_ checks the liveness and potentially other attributes of a relay.
2. _Relay Monitor_ publishes a kind `30166` note when a relay it is monitoring is online. If the monitor has a `10166` event, events should be published at the frequency defined in their `10166` note.
_Any pubkey that publishes `30166` events **SHOULD** at a minimum be checking that the relay is available by websocket and behaves like a relay_
### Clients
1. In most cases, a client **SHOULD** filter on `30166` events using either a statically or dynamically defined monitor's `pubkey` and a `created_at` value respective of the monitor's published `frequency`. If the monitor has no stated frequency, other mechanisms should be employed to determine data integrity.
2. _Relay Liveness_ is subjectively determined by the client, starting with the `frequency` value of a monitor.
3. The liveness of a _Relay Monitor_ can be subjectively determined by detecting whether the _Relay Monitor_ has published events with respect to `frequency` value of any particular monitor.
4. The reliability and trustworthiness of a _Relay Monitor_ could be established via web-of-trust, reviews or similar mechanisms.
## Risk Mitigation
- When a client implements `NIP-66` events, the client should have a fallback if `NIP-66` events cannot be located.
- A `Monitor` or `Ad-hoc Monitor` may publish erroneous `30166` events, intentionally or otherwise. Therefor, it's important to program defensively to limit the impact of such events. This can be achieved with web-of-trust, reviews, fallbacks and/or data-aggregation for example.

Web Bookmarking
---------------
`draft` `optional`
This NIP defines `kind:39701` (an _addressable event_) for a URI as a web bookmark which uses the HTTP (Hypertext transfer protocol) scheme.
These web bookmark events are _addressable_ and deletable per [NIP-09](09.md).
### Editability
Web bookmarks are meant to be editable, so they should include a `d` tag with an identifier for the bookmark. Clients should take care to only publish and read these events from relays that implement that. If they don't do that they should also take care to hide old versions of the same bookmark they may receive.
### Format
The format uses an _addressable event_ of `kind:39701`.
The `.content` of these events should be a detailed description of the web bookmark. It is required but can be an empty string.
The `d` tag is required.
In this way web bookmarks events can be queried by the `d` tag by clients, which is just their URL without the scheme, which is always and everywhere assumed to be `https://` or `http://`.
The querystring and the hash must be removed entirely, unless their requirement is explicitly stated either by the user or by some hardcoded list of URLs that rely on querystrings for basic routing provided by the client.
### Metadata
For the date of the last update the `.created_at` field should be used. For "tags"/"hashtags" (i.e. topics about which the event might be of relevance) the `t` tag should be used.
Other metadata fields can be added as tags to the event as necessary.
* `"published_at"`, for the timestamp in unix seconds (stringified) of the first time the bookmark was published
* `"title"`, title about bookmark and can be used as a attribute for the HTML link element
## Example event
```jsonc
{
"kind": 39701,
"id": "d7a92714f81d0f712e715556aee69ea6da6bfb287e6baf794a095d301d603ec7",

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

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