Jack dorsey launched a proto type of BitChat in early of July 2025. BitChat is an open-source messaging platform designed to work on Bluetooth mesh networking. It allows users to send and receive messages without requiring internet, SIM cards, or centralized servers.
BitChat provides a modern take on decentralized communication, offering
- Peer-to-peer messaging via Bluetooth Low Energy (BLE)
- Multi-hop relay, so messages can hop across several users
- End-to-end encryption using AES-256-GCM and X25519
- No account registration, no phone numbers, no tracking, no internet
The project is publicly available on github.com/permissionlesstech/bitchatGitHub
Its goal? To empower offline-first, encrypted communication, especially in high-risk, high-value, or high-censorship environments.

Seems there is an Android version available:
