About BitChat
Decentralized communication for everyone, everywhere. Built on open-source principles and cutting-edge Bluetooth mesh technology.
Our Mission
BitChat was created with a simple yet powerful vision: to enable secure, private communication without dependence on centralized infrastructure. In a world where internet connectivity can be unreliable, censored, or simply unavailable, BitChat provides a lifeline for free communication.
Built on Jack Dorsey's latest vision for decentralized technology, BitChat leverages Bluetooth Low-Energy mesh networking to create resilient peer-to-peer networks that work anywhere, anytime. Whether you're at a music festival with overloaded cell towers, traveling through areas with poor coverage, or in situations where traditional communication is compromised, BitChat keeps you connected.
Technology Stack
Core Technologies
- • Bluetooth Low Energy (BLE) 5.0+ mesh networking
- • X25519 key exchange and ChaCha20-Poly1305 encryption
- • LZ4 compression for message optimization
- • Swift implementation for iOS/macOS universal deployment
- • Adaptive duty cycling for battery optimization
Security Features
- • Ephemeral key pairs generated on each launch
- • End-to-end encryption with perfect forward secrecy
- • No persistent identity storage or user accounts
- • Cover traffic patterns to resist traffic analysis
- • Emergency wipe functionality with triple-tap gesture
Open Source Community
BitChat is completely open source, released under the MIT License. We believe that privacy-focused communication tools should be transparent and auditable by the community. Our source code is available on GitHub, where developers, security researchers, and privacy advocates collaborate to improve the platform.
The project welcomes contributions from developers worldwide. Whether you're interested in security audits, feature development, bug fixes, or documentation improvements, there are many ways to get involved and help shape the future of decentralized communication.
