Jack Dorsey, co-founder of Twitter (now X) and Block, has launched Bitchat, a new Bluetooth-based peer-to-peer messaging app that works entirely without internet, data, phone numbers, or servers. The app, currently in beta via TestFlight, reached its 10,000-user limit almost instantly. Built using Bluetooth Mesh and encrypted with Curve25519/AES‑GCM, Bitchat lets users chat within a 30m range and relay messages up to 300 m through others nearby—making it a true off-grid communication tool.
This decentralized messaging app could become a game-changer for communities with no or unreliable internet, such as rural villages or areas experiencing network disruptions. In crisis or protest situations (as seen with apps like Bridgefy in Hong Kong) Bitchat’s mesh network could provide resilient, censorship-resistant, and secure communication. Features like password-protected channels, anonymous identities, and a panic-mode data wipe offer privacy and safety tailored for high-risk scenarios.
Still in early stages, Bitchat is iOS-only in beta and hasn’t launched widely yet. Users report occasional glitches, and the mesh network depends on device density and battery life. Dorsey is working to introduce Wi-Fi Direct support and extend functionality. As it matures, Bitchat may not replace mainstream apps like WhatsApp, but could serve as a vital backup tool for Africa’s offline-first communities and activist networks.
