“Block CEO Jack Dorsey spent the weekend building Bitchat, a new decentralized, peer-to-peer messaging app that works entirely over Bluetooth mesh networks, with no internet, central servers, phone numbers or emails required. The Twitter co-founder announced Sunday that the beta version is live on TestFlight, with a full white paper available on GitHub. … Bitchat enables ephemeral, encrypted communication between nearby devices. As users move through physical space, their phones form local Bluetooth clusters and pass messages from device to device, allowing them to reach peers beyond standard range — even without Wi-Fi or cell service.” (07/07/25)
