Relay List Metadata
|
|
-------------------
|
|
|
|
`draft` `optional`
|
|
|
|
Defines a replaceable event using `kind:10002` to advertise preferred relays for discovering a user's content and receiving fresh content from others.
|
|
|
|
The event MUST include a list of `r` tags with relay URIs and a `read` or `write` marker. Relays marked as `read` / `write` are called READ / WRITE relays, respectively. If the marker is omitted, the relay is used for both purposes.
|
|
|
|
The `.content` is not used.
|
|
|
|
```json
|
|
{
|
|
"kind": 10002,
|
|
"tags": [
|
|
["r", "wss://alicerelay.example.com"],
|
|
["r", "wss://brando-relay.com"],
|
|
["r", "wss://expensive-relay.example2.com", "write"],
|
|
["r", "wss://nostr-relay.example.com", "read"]
|
|
],
|
|
"content": "",
|
|
...other fields
|
|
}
|
|
```
|
|
|
|
This NIP doesn't fully replace relay lists that are designed to configure a client's usage of relays (such as `kind:3` style relay lists). Clients MAY use other relay lists in situations where a `kind:10002` relay list cannot be found.
|
|
|
|
## When to Use Read and Write Relays
|
|
|
|
When seeking events **from** a user, Clients SHOULD use the WRITE relays of the user's `kind:10002`.
|
|
|
|
When seeking events **about** a user, where the user was tagged, Clients SHOULD use the READ relays of the user's `kind:10002`.
|
|
|
|
When broadcasting an event, Clients SHOULD:
|
|
|
|
- Broadcast the event to the WRITE relays of the author
|
|
- Broadcast the event to all READ relays of each tagged user
|
|
|
|
## Motivation
|
|
|
|
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).
