Jack Dorsey, co-founder of Twitter (now X), has launched a new messaging app called "Bitchat." This move reflects his strong interest in privacy and decentralization. What makes Bitchat unique is its complete independence from the internet or cellular networks; it operates solely on Bluetooth technology, with future plans to support Wi-Fi for expanded range and improved performance.

Bitchat creates a mesh network among nearby devices, with each device connecting to others via low-energy Bluetooth. When you send a message, it doesn't go through a central server, unlike traditional apps. Instead, it travels directly from one device to another within the geographical range, and can even relay through intermediate devices that act as bridges to reach its final destination. These intermediary devices don't read the message; they simply transmit it in an encrypted form, ensuring complete privacy.

A key differentiator for Bitchat is that it requires no registration or account creation. There's no need for a phone number, email, or even a username. The first time you launch the app, a unique, encrypted identity is generated for you, based on a public key that serves as your identifier within the network. This approach keeps users completely anonymous, much like how cryptocurrencies such as Bitcoin operate, where interactions occur between wallets without revealing real identities.

Privacy isn't just a feature of Bitchat; it's the core of the app's philosophy. Messages are encrypted using robust technologies like Curve25519 and AES-GCM, and they are never stored on any servers. The app also includes a "Panic Mode," allowing users to instantly delete all data by tapping the logo three times. This feature is designed for emergencies or when immediate information protection is necessary.

Currently, Bitchat is available as a limited beta version on TestFlight for iOS devices, having reached its maximum capacity of 10,000 users. While still in its early stages, Bitchat signals a new direction toward more free and secure communication tools, moving away from surveillance and tracking.
