Bitchat, a new decentralized messaging application created by Jack Dorsey, is now officially available to the public in the Apple App Store.
The application allows iPhone users to securely send encrypted messages without the use of the internet or a centralized server. The application was launched by the Twitter founder in beta mode on July 7.
Bitchat creates mesh networks using Bluetooth Low Energy (BLE) between nearby devices. Bitchat utilizes the Noise protocol for its end‑to‑end encryption and does not have to use phone numbers, usernames, or store messages in the cloud.
Messages are sent directly between devices within a 3.2 km radius, and messages are deleted after delivery, unless held by the app's store-and-forward function. Group chats can also be protected by a password.
