Twitter founder Jack Dorsey has revealed the white paper for Bitchat, a decentralized messaging platform working completely over Bluetooth.
The app is designed to work with out web entry, relying as an alternative on Bluetooth Low Power (BLE) mesh networks for peer-to-peer communication.
What’s Bitchat?
Bitchat is a privacy-first chat platform constructed on a store-and-forward structure utilizing BLE.
Its purpose is to supply censorship-resistant communication that is still practical even throughout web outages or infrastructure failures.
