it's been a while so I don't recall the specifics, and it's probably a really bad idea but you can convert between libsignal keypairs and torv3 keypairs
letting you have a deterministic p2p nat punching anonymous address to connect to
i'm sure someone smarter than me can like implement it securely and support multiple devices well
but if you forced people to use their onion address as a username it'd stop people correlating themselves
