bitchat is a decentralized peer-to-peer messaging application that operates over bluetooth mesh networks. no internet required, no servers, no phone numbers.

traditional messaging apps depend on centralized infrastructure that can be monitored, censored, or disabled. bitchat creates ad-hoc communication networks using only the devices present in physical proximity. each device acts as both client and server, automatically discovering peers and relaying messages across multiple hops to extend the network's reach.

this approach provides censorship resistance, surveillance resistance, and infrastructure independence. the network remains functional during internet outages, natural disasters, protests, or in regions with limited connectivity.
