Jack Dorsey launches Bitchat, a secure messaging app that doesn’t use the internet

Jack Dorsey, co-founder of Twitter, Bluesky, and Square, has introduced a private messaging application called Bitchat, which operates independently of traditional internet or cellular networks. Bitchat utilizes decentralized Bluetooth technology and end-to-end encryption for secure communication. It is based on Bluetooth Low Energy (BLE) mesh networks, extending the typical Bluetooth range from 100 meters to 300 meters. Developed with the help of an AI coding companion named Goose, Bitchat is described as a "weekend project." The app aims to provide resilient and private communication, but critics have raised security concerns about its authentication system. Dorsey has issued a disclaimer stating that Bitchat is a "work in progress" and has not undergone external security review, warning users against relying on its security until it is evaluated.

No Internet, No Problem: Jack Dorsey Unveils Bluetooth Messaging App ‘Bitchat’

Jack Dorsey, co-founder of Twitter and CEO of Block, has launched a messaging app called Bitchat, which enables communication without internet connectivity using Bluetooth mesh networking. Bitchat operates on a peer-to-peer basis, does not require user accounts, and ensures messages are encrypted and temporary, without interaction with a central server. Users can communicate within a 300-meter radius, and messages can be relayed to others beyond direct Bluetooth range. The app features password-protected group chats, delayed message delivery for offline users, and will support Wi-Fi Direct for improved range and speed. All messages are stored solely on users' devices and are designed to disappear over time. Bitchat is described as a decentralized, peer-to-peer messaging application resilient to network outages and censorship. The beta release quickly filled all 10,000 slots, indicating significant interest.
