Jack Dorsey Builds Bitchat, A Bluetooth Messaging App That Doesn’t Need Internet, Phone Numbers

Jack Dorsey has launched a messaging app called Bitchat, which operates without an internet connection by using a Bluetooth mesh network. The app allows devices to communicate directly, facilitating message exchanges without mobile data or centralized servers. Currently in beta testing on Apple TestFlight, Bitchat aims for peer-to-peer communication off the grid and incorporates "store and forward" technology for message delivery. It allows users to communicate anonymously without the need for accounts or personal information, making it suitable for privacy-conscious individuals, activists, and those in areas with restricted internet access. However, Bitchat has limitations, including range restrictions due to Bluetooth connectivity, support for only plain text messages, and potential increased battery consumption. The app is still in development and not fully polished.
