Jack Dorsey has introduced Bitchat, a messaging app that operates without internet connectivity by using Bluetooth technology for direct messaging. The beta version is available via TestFlight, and a white paper is accessible on GitHub. Bitchat functions as a peer-to-peer platform, leveraging Bluetooth mesh networks to allow users to exchange encrypted messages without requiring internet access, central servers, phone numbers, or email addresses. Messages can travel up to 300 meters by relaying through other devices. All messages are stored on users' devices, disappear by default, and do not pass through central servers, prioritizing user privacy and resistance to censorship. Bitchat allows for group chats called “rooms” and includes a feature for saving messages for offline delivery. Future updates will introduce WiFi Direct capabilities. Following the announcement, all 10,000 beta spots were filled.
