Jack Dorsey, known for his advocacy of decentralization, has taken a bold step into the realm of hands-on experimentation with the launch of a new messaging application, Bitchat. Over the recent weekend, Dorsey, who serves as CEO of Block and co-founder of Twitter, introduced this innovative platform that operates outside the conventional internet framework.
Revolutionizing Communication
Bitchat distinguishes itself by eliminating the need for a phone number and refraining from storing data on a server. Instead, it utilizes Bluetooth technology to transmit messages directly between devices. This unique approach allows users to communicate without relying on a data plan or Wi-Fi connection. When users are in proximity to one another, messages can be relayed through a chain of devices, extending the reach of communication beyond standard Bluetooth capabilities, potentially up to 300 meters in optimal conditions.
In a departure from traditional messaging apps, Bitchat does not feature usernames, chat backups, or lengthy inbox histories. Conversations are designed to be ephemeral, with messages encrypted and stored locally before disappearing. This streamlined approach aims to bypass servers and tracking mechanisms entirely, aligning with Dorsey’s vision for a more user-centric digital experience.
While Bitchat is not the first app to explore this decentralized communication model—Bridgefy previously gained attention for similar functionality during protests in Hong Kong—it is built from the ground up according to Dorsey’s specifications. The beta version of the app launched on Apple’s TestFlight, quickly filling its initial allocation of 10,000 testing slots.
Accompanying the launch, Dorsey shared a white paper outlining the project as a personal experiment. This document delves into the principles of Bluetooth-based networking, message relays, encryption techniques, and data transfer devoid of central control.

Bitchat currently supports small group chats, allowing users to create rooms, tag them with hashtags, and implement password protection for added privacy. Future updates are expected to introduce WiFi Direct support, enhancing message delivery speed and range while maintaining the app’s offline capabilities.
In contrast to established messaging platforms like WhatsApp or Messenger, Bitchat offers a radically different experience. It strips away the complexities of profiles, syncing, and cloud storage, focusing instead on direct, unmediated communication between devices. Whether Bitchat evolves into a widely adopted tool or remains a niche project, it embodies Dorsey’s commitment to fostering simpler, user-controlled technology. With no grand announcements or fanfare, this new tool is quietly being shared among users, reflecting a grassroots approach to modern communication.
