If you’re talking peer-to-peer then DAT Foundation (their DAT protocol) is getting more traction. Very differently positioned to SAFE (which has a very good completeness-of-vision), the recently revamped protocol gets some nice application (I am not really following them, so do not have many pointers… they can be hard to find). Recently I came upon CoBox, a cool DAT-based project providing “an encrypted p2p file system and distributed back-up tool”.
You also have Secure Scuttlebutt Foundation and the aforementioned IPFS suite of protocols. I am very interested in Fediverse (ActivityPub), which right now is federated-only, but there’s increasing amount of research into peer-to-peer usage. ActivityPub itself is just a messaging protocol and mostly agnostic to this. A wonderful development for Fediverse is Spritely Project.
