NIP-FA

Kind-scoped follows

draft optional

This NIP defines kind 967, a kind-scoped follow event.

{
  "kind": 967,
  "tags": [
    ["p", "<followed-pubkey>", 'relay-url'],
    ["k", "<some-kind>"],
    ["k", "<some-other-kind>"]
  ]
}

Multiple p tags and multiple k tags are allowed.

The k tag(s) define the scope of the follows.

Unfollow action

Unfollowing is done by deleting the follow event, copying over the k tags from the follow event.

{
  "kind": 5,
  "tags": [
    ["e", "<follow-event-id>"],
    ["k", "<some-kind>"],
    ["k", "<some-other-kind>"]
  ]
}

Constructing specialized follow lists

A client can fetch the events of the kinds they are interested in, and perhaps adjacent kinds if they choose to. For example, a client specialized in videos might also want to extend its computed follow list to include events related to live streams.

Clients can use the last kind:967 and kind:5 tagged with a k they care about and use the last created_at they have seen to REQ for updates.
