Also worth explicitly mentioning SSB-style cryptographic “implicit identity”. Connecting consists of exchanging public keys (which can be global per person, or compartmentalized per contact/conversation). Rather than a central server relating messages to the right peers, there’s a global feed where you attempt to decrypt everything and the ones which succeed are obviously addressed at you. The benefit here is that not even a central server operator like Signal can trivially tie messages or chat identities to peers.
