Maybe some sort of CRDT + gossip network? But at that point you are quite close to a blockchain.
(Not that I'm confident such a thing is a good idea, but I do think that a decent portion of the blockchain stack makes sense given the idea)
Data can be:
- decentralized
- public
- immutable
- redundant
- verifiable with asymmetric cryptography
..without being part of a blockchain. The technology to do this has existed much longer than blockchain has as a concept. Torrents are a good example.
