@racchio there has been a lot of chatter about it on https://scuttlebutt.nz over the years, if you care to install Yet Another Distributed Social Network to dive deeper. It is the usual rhetoric & dog-whistles in #Nostr projects- "complete freedom of expression" "without the risk of de-platforming" predictably attracts bigots who want to shout hateful things. 'Big Tent' philosophy and the 'Nazi bar' outcome etc etc https://startup-weekly.com/Primal-launches-new-social-network-for-digital-freedom/
@racchio I don't know much about #Nostr, other than that it's a fascist-run project with a disastrous cultural history. But yes, #Keet is for IM and runs fully decentralised.
(I'm going to use that word rather than "distributed" as the architecture *does* actually facilitate the distribution of power as well as of compute & storage. It's also built by a pretty cool community of anarchists & anarcho-syndicalists, at least the ones I've met.)
