Bitchat Review: How Jack Dorsey’s Private Offline Messenger Works

Bitchat employs the Noise Protocol Framework, specifically the XX pattern, for encrypted and authenticated communication. The Android version uses X25519 for key exchange and AES-256-GCM for message encryption. Bitchat operates without a central infrastructure, phone numbers, or traditional accounts, which reduces data collection and risks of censorship and surveillance. The app relies on Bluetooth connectivity, requiring physical proximity between users, which can enhance security but may lead to device identification. Metadata about nearby devices and connection instances may still be retained. Bitchat has not yet undergone a comprehensive external security audit, raising concerns despite its focus on privacy and encryption.
