✖️ XChat is built on Rust with "Bitcoin-style" encryption. It is "a completely new architecture," commented Elon Musk.
↪️ XChat, an enhanced version of direct messages (DM), would employ some type of elliptic curve algorithm in its encryption.
💬 Bitcoin uses ECDSA, an elliptic curve focused on digital signatures. It is possible that XChat uses some algorithm of this kind, as WhatsApp and Signal already do.
