#Tor and #ActivityPub experts, I'm curious to know if anyone has attempted to create a Fediverse instance as an Onion Service.

I understand that server-to-server communications in ActivityPub use HTTPS POST. So I imagine the sticking point would be routing server-to-server communications over the Tor network from, say, mastodon.social to valencia.onion.

Is this a problem with a trivial solution? Or perhaps an intractable one?
