## Feeds & Metafeeds
|
|
|
|
- Peers maintain a list of feeds they subscribe to
|
|
- When peers connect, they ask for updates to subscribed feeds
|
|
- Metafeeds can provide metadata about other feeds, and can form a tree structure with other Metafeeds as subfeeds.
|
|
- {index}`Bencoded <single: Encoding; Bencoding>` rather than JSON.

Uses for metafeeds
|
|
|
|
- Storing multiple network identities with a special feed off the user's root metafeed. (contents of metafeed entries can be encrypted)
|
|
- Allow for multiple devices to use the same identity - https://github.com/ssbc/fusion-identity-spec
|
|
- Device A `invite`s Device B to identity
|
|
- Device B `consent`s
|
|
- Device A `entrust`s phone with private key
|
|
- Device B posts a `proof-of-key` message
|
|
- If device B lost, `tombstone` the fusion identity message
|
