Jack Dorsey, the co-founder of Twitter, has unveiled Bitchat, a beta messaging app that operates without an internet connection and is based on Bluetooth technology. The app promises a reliable and secure communication method when traditional networks are unavailable.
Bluetooth Mesh Architecture for Decentralized Communication
Bitchat operates on a custom mesh networking protocol using Bluetooth Low Energy technology. Each device acts both as a central client and a peripheral server, allowing for automatic message relay between connected devices. The system forms local clusters based on the physical proximity of devices within a 30-meter range.
Message Relay and Privacy Features
Messages in Bitchat are encrypted and ephemeral, meaning they disappear after delivery. The app allows for automatic caching of messages when recipients are out of reach, storing them until they return to the network. All messages are protected by end-to-end encryption, and no phone numbers or email addresses are required for account creation.
Use Cases Targeting Infrastructure-Independent Communication
Bitchat provides solutions for equal communication when traditional networks become unavailable. Users can exchange messages at conferences without relying on Wi-Fi, as well as in protest situations or during natural disasters when internet connectivity is lost. Jack Dorsey developed Bitchat as a weekend project to explore mesh networking concepts.
The Bitchat application represents an intriguing step in the realm of decentralized communication, providing opportunities for secure and independent messaging in various conditions.
