I think you're pretty much describing Solid

Though I could be wrong. I never fully grokked Solid last time I read about it.

That and Mastodon, ActivityPub and IPFS are examples of the sort of thing I have in mind.

Also the decentralised flood-fill model of Usenet.

You can't move between Mastodon instances and keep your followers.

And that's a poor design decision. Why should it matter.

I'm envisaging something like mastodon, not something that is mastodon.

Can you tell me what you mean by flood-fill ? I'm looking at different strategies for sync'ing activity between domains, and ActivityPub / IPFS seem like a lot of conceptual overhead. I'd rather just rsync directories on my friends' servers.

OK, imagine a load of servers. Each is connected to some (not all) of the others, and they all peer messages to each other.

     A -- B -- C -- D
          |    |
          E -- F -- H
          |
          G -- I

A message M is sent to one (say A). B asks A "have you got any new messages?" (or it might be A pushes them onto B) and A replies with M.

From B, M is sent to C and E. From E it is sent to F and G. Eventually it gets to all the servers on the network.

I envisage that each message would have a unique ID consisting of a cryptographic hash of its contents and timestamp.
