There's two scenarios in which we're leaving a community:
We either get kicked or we leave ourselves.
In case of leaving ourselves it's fine to unsubscribe from further
community updates be cause we deliberately chose to leave.
In case of being kicked however, this is different.
Say I'm kicked from a community because its token permissions have
changed, in this case we don't want clients to manually re-subscribe to
the community to get informed when there were further changes.
status-go should rather not unsubscribe if we know for sure we've been
kicked by someone else.
applicationmetadata/ is an outer layer wrapping a payload with an app-specific metadata like a signature.
identity/ implements details related to creating a three-word name and identicon.
migrations/ contains implementation specific migrations for the sqlite database which is used by Messenger as a persistent data store.
History
Originally this package was a dedicated repo called status-protocol-go and was migrated into status-go. The new status-go/protocol package maintained its own dependencies until sub modules were removed and the root go.mod file managed all dependencies for the entire status-go repo.
