Is it possible to use Matrix purely over Tor? (piefed.social)

Could you host a matrix server using only the Tor network? If so it would make it possible to have a communication tool thats not only encrypted but anonymous, I assume much would have to be changed and maybe federations wouldn't work at all but would it be theoretically possible?

I mean it would make way more sense to use one of the many messengers that explicitly use TOR like Cwtch or Briar.

    Yes and federation works. The caveat is that since Matrix s2s de facto mandates TLS certs, you'll need to use self-signed certs as well as accept them from other onion peers. I've been aware of some more involved setups where a server name on the clearnet can be manually mapped to its Tor onionsite as well.

    Beyond that, c2s is just a simple HTTP service, and most clients should support it assuming they have a way to hop on Tor (Orbot, SOCKS5 proxy etc)

    I think it's possible to run anything that can be run over a network over Tor. Tor can be set up as a proxy for any piece of software.
