Twitter Co-Founder Jack Dorsey has announced a new decentralised messaging app, Bitchat, which will be a peer-to-peer public domain messaging project.
Taking to X (formerly Twitter), Dorsey stated that Bitchat is said to offer a more secure method of messaging, protected with end-to-end encryption. The app does not require internet, an account, or even a phone number to function.
In addition, other features include a favourites system, mentions, and rooms for topic-based conversations.
Bitchat features
The app is currently available in beta via Apple's TestFlight programme, although the slots were taken up soon after it was announced.
Bitchat is said to leverage Bluetooth Low Energy (BLE) mesh networking which enables direct peer-to-peer messaging within physical proximity. It has a range of approximately 30 metres within which, each device serves as both a central (client) and peripheral (server).
Bitchat provides automatic caching when the recipient is unreachable, with the messages getting delivered when the peer returns.
Moreover, the messaging platform offers end-to-end encryption, protected by Curve25519 elliptic curve and AES-GCM authenticated encryption algorithm as part of a multi-layered encryption setup.
It is worth noting that Bitchat does not require any phone numbers, emails, or permanent identifiers to work, as per Dorsey.
Bitchat launch
The company has yet to officially reveal the launch date of the Bitchat app and its availability in countries.
