Jack Dorsey, CEO of Block, has launched Bitchat, a decentralised messaging app that enables private, peer-to-peer communication over Bluetooth mesh networks. Bitchat works without the internet, central servers, phone numbers, or emails, offering users a fully offline, privacy-focused way to connect.
The Twitter Co-Founder that the beta version is live on TestFlight, with a full white paper available on GitHub.
In a post on X, Dorsey called it a personal experiment in “Bluetooth mesh networks, relays and store and forward models, message encryption models, and a few other things.”
Bitchat enables ephemeral, encrypted communication between nearby devices. As users move through physical space, their phones form local Bluetooth clusters and pass messages from device to device, allowing them to reach peers beyond standard range — even without Wi-Fi or cell service.
Certain “bridge” devices connect overlapping clusters, expanding the mesh across greater distances. Messages are stored only on the device, disappear by default and never touch centralised infrastructure — echoing Dorsey’s long-running push for privacy-preserving, censorship-resistant communication.
The launch builds on his support of Damus and Bluesky and reflects a broader campaign to decentralise everything from social media to payments.

The app also supports optional group chats, or “rooms,” which can be named with hashtags and protected by passwords. It includes store-and-forward functionality to deliver messages to users who are temporarily offline.
A future update will add WiFi Direct to increase speed and range, pushing Dorsey’s vision for off-grid, user-owned communication even further.
Unlike mainstream messaging platforms such as Meta’s WhatsApp and Messenger, which are owned and built by big tech companies and rely on personal data, Bitchat operates entirely peer-to-peer with no accounts, no identifiers and no data collection.
