gun VS sandstorm-earthstar-foyer

I've been doing some experimentation along the same lines ... I've got a small proof-of-concept working where I can sync Earthstar databases between multiple Sandstorm instances - each "grain" acts as a pub, and you can use "webkeys" as pubs. I'm using powerbox-http-proxy to request capabilities for connections, so it works even with fully sandboxed client-side networking (ALLOW_LEGACY_RELAXED_CSP=false). It's maddeningly complex to do simple networking, but it's amazing to have the security layer there. I'll put together a blog post / video soonish.

Sandstorm is very interesting for privacy-focused peer-to-peer because it has the tools in place to sandbox networking. The networking security model is designed to prevent things from talking to each other without user approvals - so it's extra tricky to do peer-to-peer things with it.

I'm excited to try to stick some of my old IPFS/IPLD/libp2p/Dat/CRDT things into Sandstorm - there's a tonne of interesting things that could be done with it.
