encryption security

Jack Dorsey has introduced Bitchat, a decentralized messaging application that operates using Bluetooth Low Energy (BLE) mesh networks for peer-to-peer messaging without traditional internet connectivity. Bitchat features end-to-end encryption for security, operates independently of the internet, and allows users to send messages over a range of more than 300 meters. Each device functions as both a client and server, enabling multi-hop message delivery. Messages are ephemeral by default, with a caching feature for recipients who are temporarily unavailable. Regular messages last 12 hours, while favorites are retained indefinitely. Bitchat does not require phone numbers or email addresses, enhancing user privacy, and includes features such as mentions and topic-based discussion rooms that can be password-protected. The app is currently in beta testing via Apple's TestFlight program.
