As answered by people managing Bit-Chat.xyz and Codegres.org.
Bit-Chat.xyz's answer
Completely Offline: No Wi-Fi, SIM card, or any servers required. All messages are relayed between devices through multi-hop Bluetooth Low Energy (BLE) mesh networking.
End-to-End Encryption + Perfect Forward Secrecy: Temporary key pairs are generated on each startup, with ChaCha20-Poly1305 encryption and X25519 handshake, ensuring messages cannot be eavesdropped on or replayed by third parties.
Anonymous and Lightweight: No account system, no phone or email registration, and no persistent identity. The application is small in size, runs efficiently, and has extremely low battery and bandwidth consumption.
Open Source Transparency: The protocol and client code are fully open source, allowing anyone to audit, deploy, or further develop them.
Bit-Chat.xyz's answer
True Decentralization: Unlike Briar, Bridgefy, etc., which still rely on certain servers or supporting services, BitChats can be deployed with "zero infrastructure."
Full Anonymity: No registration is required; it's ready to use upon launch. Keys reside temporarily in memory and are discarded after use.
Strong Fault Tolerance: Multi-hop routing and store-and-forward automatically bypass interrupted nodes, making the network more stable.
Cross-Platform Consistency: iOS/Android/macOS CLI all support the same protocol stack, allowing seamless message transfer between different systems.
Bit-Chat.xyz's answer
Individuals and organizations with a strong emphasis on privacy and security (journalists, human rights activists, NGOs).
Users in scenarios requiring offline communication (outdoor adventurers, disaster relief teams, music festival/exhibition attendees).
Tech-driven communities (open-source enthusiasts, decentralized technology researchers, geek gamers).
Bit-Chat.xyz's answer
In July 2025, Jack Dorsey personally experienced the fragility of traditional communication during a blackout drill, which sparked the idea of "staying connected even in an off-grid era." He then open-sourced a chat protocol based on BLE Mesh called BitChats, aiming to enable people to connect freely and securely with each other when any network infrastructure collapses. The community responded quickly, and in recent months, field tests have been completed in multiple extreme scenarios.
