Cwtch: Decentralized, Surveillance Resistant Infrastructure

cross-posted from: https://lemmy.toot.pt/post/346

"Cwtch is decentralized and focused on metadata-privacy in addition to communications privacy. Unlike other communication platforms, none of your messages are routed through a centralized server that has access to metadata such as your social network of friends, or who sent and received a particular message."

Looks like it's based on the onion-routed protocol used in Ricochet, so should be fairly robust (but not yet audited).
