ssb-same-as

A scuttlebot plugin that provides a stream of which feeds are (and are not) the same as other feeds.

The basis for creating the illusion of multi-feed identities in SSB!

Based on ssb-friends and graphreduce

TODO

• [ ] need to test merge blocking and unmerging
• [ ] hook into replication to ensure the correct feeds are replicated
• [ ] improve realtime performance (avoid re-traversing entire graph)

Spec

Assert that you are the same as another feed

pe: 'contact',
ntact: TARGET_FEED_ID,
llowing: true, // for backwards compat reasons
meAs: true

Block a sameAs

pe: 'contact',
ntact: TARGET_FEED_ID,
llowing: true, // for backwards compat reasons
meAs: false

Agree with another feed's assertion

pe: 'contact',
ntact: TARGET_FEED_ID,
llowing: true, // for backwards compat reasons
meAs: {
SOURCE_FEED_ID: true // or `false` to remove an agreement

Logic behind sameAs resolution

• If one side explicitly disagrees (with a sameAs: false), the identities will NEVER be merged.
• If both sides agree, the identity will ALWAYS be merged.
• If one side agrees (and the other side has not shared an opinion), and you agree, then the identities will be merged.
• In all other cases, the identities will not be merged.

This module uses graphreduce to walk the sameAs links, so this means that any topology of links will be resolved.

Exposed API (as sbot plugin)

sbot.sameAs.stream({live: false, sync: true, old: true}) source

Gets a list of all of the resolved and verified sameAs links between feeds.

m: 'a', to: 'b', value: true}
m: 'a', to: 'c', value: true}
m: 'a', to: 'd', value: true}
m: 'b', to: 'a', value: true}
m: 'b', to: 'c', value: true}
m: 'b', to: 'd', value: true}

sbot.sameAs.get({id}, cb) async

Gets a list of all of the verified sameAs links for a given feed.
