A community dedicated to fediverse news and discussion.
Fediverse is a portmanteau of "federation" and "universe".
Getting started on Fediverse;
This fediverse at least. AT Protocol, used for bluesky, supports nomadic identity. Instead of accounts being @user@domain.tld, they attach your domain / home instance / whatever, to a DID. You can read more about it in their various spec pages but here's the one for DIDs.
Well, Hubzilla / Streams, using Zot, which can federate over activity pub also have nomadic identity apparently, while I've read ActivityPub authors say that nomadic identity could be done on it but that no one has put the work in ... so it's not so clean cut as that.
Also ... I don't think BlueSky can be called a "fediverse" yet until decentralisation is shown to work well let alone until they even allow it and open signups. However much promise their tech/protocol has they, at the moment, are rather behind in terms of growth and scale.
