I guess this is when it gets fuzzy. A true peer-to-peer social network would mean that every node has to be able to get everything and also be able to share whatever it has with every other node. If every participant on this kind of social network was required to maintain their own "seedbox", then it implicitly limits access to only people with means.

But if there were hubs funded by groups of interested people that allowed those folks to share the cost of "seeding" and in return only "leech" the information they care about... then isn't that essentially the same kind of decentralization that already exists on the fediverse? The way I understand it, instances are set up by communities of people with similar interests and those instances are configured to only propagate a subset of the events that their community is interested in.

how i solved for this was reciprocal pinning so any node owns all their data (personal log) + whoever they follow (mutual follow reprocity) last x content (indices so its easy to get last n, or last since xyz) and so anyone can decide exactly what they keep or not on their node and thus share by simply following or not (maybe two level, so you can choose to not pin people you follow) heh, smt like that

anyways the idea is very much to do like bittorrent or kademilia but for social media posts i need to research more the fediverse before building anything tho

That's more or less what atproto is, except the indexer is called a relay and provides the data directly. Currently bluesky is providing their relay for free, but I don't believe there's any reason they couldn't make it paid in the future.

yeah they had an outage in 2024 i think or was that registrations only?
