Not yet. Is it a matrix over tor?
I think its own protocol. Mostly matrix isn’t p2p.
How many time it took for you? https://image.nostr.build/896582b73e9f39881a54da8605301653fcd33c56fb1168bdb4ec8433d984e2c2.jpg
it might be Tor is censored in your region. That's why you can't connect.
it's connected now, took a some time in background. I'm in France, tor is not censored yet 🤗
orbitdb is IPFS/libp2p. ( https://github.com/TryQuiet/quiet?tab=readme-ov-file#how-it-works )
