Jack Dorsey — Twitter, Bluesky, and Sq. co-founder and Bitcoin evangelist — is now taking over the world of personal messaging apps.

Introduced earlier this week, Dorsey’s newest mission is known as Bitchat, a reportedly safe and personal messaging app that does not want to connect with the web or cell service in any respect. As a substitute, Dorsey explains in a latest white paper revealed on GitHub, the end-to-end encrypted app makes use of decentralized Bluetooth tech to attach one person to a different — a sort of offline communication popularized by apps like Bridgefy and most popular among the many privacy-focused.

The system Dorsey is hinging his newest mission on is named Bluetooth Low Vitality (BLE) mesh networks. These networks historically have restricted vary — most Bluetooth connections work inside 100 meters — however Dorsey claims his new tech can lengthen to 300 meters (or 984 toes). The app, which Dorsey known as a “weekend mission,” was coded utilizing the assistance of Goose, an open-source AI “vibe coding” assistant constructed by his firm Block.

“bitchat addresses the necessity for resilient, personal communication that does not rely upon centralized infrastructure,” Dorsey writes. “By leveraging Bluetooth Low Vitality mesh networking, bitchat allows direct peer-to-peer messaging inside bodily proximity, with computerized message relay extending the efficient vary past direct Bluetooth connections.”

Nevertheless, the tech founder’s guarantees of a completely decentralized, safe platform have already been known as into query by customers and consultants, partly as a result of a doubtlessly susceptible authentication system that would enable a malicious actor to intercept the safe connection. Dorsey has since added a disclaimer alongside a word that the mission is a “work in progress.” The disclaimer reads: “This software program has not obtained exterior safety overview and will comprise vulnerabilities and doesn’t essentially meet its acknowledged safety objectives. Don’t use it for manufacturing use, and don’t depend on its safety in anyway till it has been reviewed.”
