JACK DORSEY LAUNCHES A WHATSAPP MESSAGING RIVAL BUILT ON BLUETOOTH

Summary from the TLDR newsletter

Bitchat is a decentralized, peer-to-peer messaging app that works entirely over Bluetooth mesh networks - no internet, central servers, phone numbers, or emails required. It enables ephemeral, encrypted communication - nearby devices form clusters and pass messages from device to device, allowing them to reach peers beyond standard range, even without Wi-Fi or cell service. Messages are stored only on-device, disappear by default, and never touch centralized infrastructure. A beta version of Bitchat is currently live on TestFlight.
