Overview

• Bitchat routes messages directly between devices using Bluetooth Low Energy mesh networks without internet or user accounts
• All messages are end-to-end encrypted, stored only on individual phones and set to disappear by default for privacy and censorship resistance
• Bridge nodes link overlapping Bluetooth clusters to extend message delivery up to 300 meters beyond standard range
• An open-source whitepaper on GitHub outlines Bitchat’s decentralized architecture, store-and-forward messaging model and encryption protocols
• Developers plan to add Wi-Fi Direct support for higher speeds and greater reach and are working on an Android client to broaden platform availability
