What is Bitchat?

Bitchat is a groundbreaking decentralized messaging app, allegedly developed by Jack Dorsey, that functions without internet via Bluetooth mesh networks. It serves as 'the side-groupchat' for effortless offline communication, requiring no servers or phone numbers. This cutting-edge app leverages automatic peer discovery and multi-hop message relay, ideal for situations where internet-based messaging is unavailable, such as remote locations or emergencies.

How to use Bitchat?

To get started with Bitchat, either set up the development environment by cloning from GitHub and using XcodeGen (or run `just run` on macOS) or install the pre-built iOS app or Android APK. After launching, choose a nickname, and the app will connect to nearby peers via Bluetooth LE mesh. Join channels with IRC commands like `/j #general`, list channels with `/channels`, or chat in public local channels. Advanced options include private messaging with `/m @name message`, securing channels with `/pass password`, and managing users with `/block @name`. Messages are relayed through the mesh to reach distant peers.
