permissionlesstech/bitchat
Summary
permissionlesstech/bitchat describes a decentralized, dual-transport peer-to-peer messaging app that works offline via Bluetooth mesh and online via the Nostr protocol, with no accounts or central servers. It emphasizes privacy through end-to-end encryption (Noise for mesh, NIP-17 for Nostr) and includes location-based channels, IRC-style commands, and an emergency wipe feature. The repo provides setup instructions for Xcode and a just-based workflow, and is released under an open/public-domain license.
