BitChat is a P2P messaging app that works without internet, cell towers, or any other infrastructure.
Using Bluetooth Low Energy (BLE) network technology and the Noise Protocol Framework, it provides secure, private communications.
— The main innovation is that BitChat combines Bluetooth mesh networks, the Noise protocol for encryption, and ephemeral IDs for enhanced privacy.
Until now, there have been no messengers on the market that combine all three of these qualities.
