Xmpp is the best solution for chat or social media.
Change my mind.

@ravenclaw if ricochet.im received way more community development then I could say this. It is decentralized, free of meta data, secure and anonymous. Well the last two may not be true unless this thing gets some much needed updates.

@Untersuchende well. I never heard about ricochet.
But i think self hosting xmpp server is enough.
Don't forget to make your server only accessible trough tor it's address.
Tell your "user" to choose the encryption they liked and you're done.

@ravenclaw ah ricochet is an interesting concept. It creates an onion site (whole separate concept) and each user has their own. Basically no server is needed just multiple contacts. Encryption is done through the onion technology as .onion websites/tech have its own encryption outside of Tor .
Can't explain in a toot. Check it out when you get a chance
