Overview

• Bitchat is now available in an early iOS TestFlight beta that has reached full enrollment and is limited to iPhones.
• The messenger uses Bluetooth Low Energy mesh networking to relay end-to-end encrypted messages up to seven hops without any user registration or central servers.
• Dummy traffic and random delivery delays conceal metadata and usage patterns to enhance user privacy and resist censorship.
• Future updates aim to integrate Wi-Fi Direct for higher bandwidth connections and LoRa for long-range transmissions beyond BLE’s limited range.
• The app’s reliance on device proximity restricts range to dozens of meters per link and requires a dense user network for reliable communication.
