This sounds like what I wanted from GNU Social when I first joined over a year ago. GNU Social/Mastodon is a fun idea, but it falls apart when you realise that you still don't own your content and it's functionally impossible to switch nodes like it advertised, along with federation being a giant mess.
I tried to switch what server my account was on halfway through my GNU Social life, and you just can't; all your followers are on the old server, all your tweets, and there is no way to say "I'm still the same person". I didnt realise I wanted cryptographic identity and accounts until I tried to actually use the alternative.
That's also part of the interest I have in something like Urbit, which has an identity system centered on public keys forming a web of trust, which also lets you have a reputation system and ban spammers which you can't do easily with a pure DHT.
