Jack Dorsey, co-founder of Twitter and CEO of Block, has launched the beta version of Bitchat, a decentralized messenger that operates over Bluetooth. This application allows for encrypted conversations without internet infrastructure.
Overview of Bitchat
Bitchat uses Bluetooth Low Energy mesh networks with a 30-meter range to relay messages between devices. The app requires no central servers, accounts, or registration, providing ephemeral messaging with end-to-end encryption.
Technical Architecture and Privacy Features
The white paper outlines Bitchat's fully decentralized architecture, eliminating the need for central servers and infrastructure dependencies. Messages only exist in device memory and are not stored in any central database. Notably, each device acts as both a client and a peripheral, creating a self-organizing network.
Use Cases and Market Context
The system targets scenarios where internet-based messaging is unavailable or poses security risks. These include conferences, protests, and disaster areas. Dorsey has previously worked on issues of data privacy, which is reflected in this project.
Bitchat demonstrates that secure, private messaging can be achieved without centralized infrastructure by combining Bluetooth technologies and encryption.
