@glyn Decentralised identity has been available for longer than Mastodon, let alone ActivityPub. Only that it is known as "nomadic identity" here.

It was first implemented by Friendica creator @Mike Macgirvin ?️ in the Zot protocol in 2011 and in a Friendica fork named Red in 2012, later renamed into the Red Matrix, eventually reworked and renamed into Hubzilla in 2015.

Proof: This Hubzilla channel of mine actually simultaneously resides on two servers.

(Almost) everything that Mike has made afterwards, forks and forks of forks of Hubzilla, used to have or still have nomadic identity implemented.

His streams repository contains a fork of a fork... of Hubzilla that intentionally has no name, and that offers nomadic identity via the Nomad protocol with better compatibility with non-nomadic ActivityPub. In July, it had decentralised IDs as per FEP-ef61 (see also here) implemented, a first step by Mike to fully implement nomadic identity in ActivityPub.

Forte, Mike's most recent fork from August, had all support for Nomad and Zot6 removed and only uses ActivityPub anymore while still offering nomadic identity. To my best knowledge, however, it has yet to be declared stable enough to be daily-driven, and it has no public instances.

Other than all this, a non-public development version of @silverpill's Mitra has nomadic identity via ActivityPub in development. I'm not sure whether FEP-ef61 is implemented in the release version yet. It's the only Fediverse project aiming to implement nomadic identity which Mike Macgirvin has nothing directly to do with.

The ultimate goal is to be able to clone a Fediverse identity across project borders. Only considering stable releases, it's currently only possible to clone Hubzilla channels within Hubzilla, using Zot6, or (streams) channels within (streams), using Nomad.

Unfortunately, Mike has officially retired from Fediverse development and only occasionally submits code to the streams repository and Forte anymore.
