How should group chats work in decentralized systems?

The hardest problem is social. Who is going to use this?

I agree, and since there is no mobile version, this won't replace your whatsapp, and it was never designed for that. The actual people I see using this: - People who want anonymous messaging (I realize that there are already Tor messengers, so the idea was to make this one much more feature rich) - Friend groups that want private group chats without any central dependencies or accounts - security, self-hosting, decentralization and open-source enthusiasts

One option that you sort-of mentioned but missed: go with the static groups, but don’t let the users feel that.

In other words, show the kick/invite options to users when it does happen, but destroy and create a new group behind the scenes.

I understand the vision, but I would still have to rotate keys through different groups. It doesn't solve anything, it just gives the illusion of a clean group delete-then-rebuild

This is a nice little write up and I kinda feel like the author (sensibly) chose centralization just on a smaller scale. I also think that the algorithm is pretty similar to the og textsecure2[1] protocol signal used (and still uses?) in terms of key generation. It's different in that messages are in a distributed hash table instead of sent through a server and also that there's less cross-verification by chat members, but I'm not sure the author would lose any of their goals by using the signal approach (with distributed storage).
