The fediverse is federated (it's in the name). This is distributed (P2P). They're fundamentally different concepts in the underlying protocol so compatibility is a bit odd to think about here. There are certainly overlaps in the two concepts and certain parts of them can be compatible to a small extent: a bunch of people have compared Bluesky Social's AT protocol to SSB despite the former being federated & the latter being p2p. But similarities aside they can't really be compatible at protocol level.
