Jack Dorsey introduced a test version of a decentralized messaging application called Bitchat, designed for private conversations through end-to-end encryption. The app enables ephemeral, encrypted communication without relying on internet infrastructure, making it resilient to network outages and censorship. Bitchat operates using Bluetooth to facilitate communication within a range of approximately 300 meters and does not require users to provide phone numbers or email addresses. Instead, users create their own handles for identification. The app automatically detects nearby users, allowing them to connect through chatrooms. Bitchat is intended for use in scenarios lacking internet access, such as concerts, airplanes, or during disaster response efforts.
