The protocol could require “dual-homing” user accounts, where each account is automatically replicated on 2 different instances without need for hacks and workarounds. That would prevent users from losing their account if an instance is shut down, and also make it easy to migrate to a new instance without losing followers etc. The clients following your account always check for updates on both instances and if you move one of your accounts they update automatically.

Sounds like Nomadic identity from the Hubzilla and Streams projects.
