📡 bitchat: Jack Dorsey’s off-grid messenger for the end times
Twitter cofounder Jack Dorsey just dropped bitchat — a fully decentralized messenger that doesn’t need the internet. You read that right.
It uses Bluetooth Low Energy to build a mesh network between phones. Each phone becomes a mini-server, passing messages down the line until they reach the target. Messages are encrypted, cached, and there's no signup — no phone number, no email, no nothing.
Right now it’s just text chats, but media sharing and Wi-Fi support are coming. The source code’s on GitHub, and the iOS TestFlight? Already full.
So yeah — when the grid goes down, you can still slide into the DMs.
