In a move that has captured the attention of tech enthusiasts and privacy advocates, Jack Dorsey, co-founder of Twitter and CEO of Block, has launched “Bitchat,” a new messaging app that operates without an internet connection.
The app, which he reportedly developed over a weekend, has been sparking conversations about the future of communication and the possibility of a “free internet” powered by decentralized technologies.
So, how does Bitchat work, and does it really offer a path to a free internet with Bitcoin?
Bitchat’s core technology is a Bluetooth mesh network. Instead of relying on a central server, Wi-Fi, or cellular data, the app uses Bluetooth Low Energy (BLE) to create a peer-to-peer network of nearby devices. Messages “hop” from one user’s phone to another, extending the communication range far beyond a single device’s typical Bluetooth range. This decentralized structure makes it resilient to network outages and censorship, as there’s no central point of control to shut down.
Privacy is a key focus for Bitchat. The app is end-to-end encrypted, doesn’t require a phone number or email to sign up, and has a “panic mode” to instantly wipe all local data. This commitment to user privacy and a server-free model is what has drawn parallels to Bitcoin’s own decentralized philosophy.
While the connection to Bitcoin is more philosophical at this stage, some reports have indicated that the app is already being used for offline Bitcoin transactions. A user can create and sign a transaction, which is then passed through the mesh network until a device with an internet connection can broadcast it to the main Bitcoin network. This “store-and-forward” mechanism is a significant innovation for payments in areas with poor or no connectivity.
However, the idea of Bitchat building a “free internet” with Bitcoin comes with its own set of challenges. The app’s range is currently limited, and its effectiveness depends on the number of users in a given area. It’s a messaging app, not a full-fledged internet replacement, and the speed and reliability are not yet on par with traditional services. While it’s a promising step toward more resilient and private communication, it’s a long way from replacing the global internet infrastructure we rely on today.
Bitchat is currently available for iOS and macOS, with an Android version planned. It’s an open-source project, meaning anyone can inspect the code, though the app’s developers have issued a warning that it has not yet undergone a full security review. Still, as a proof-of-concept, Bitchat is a fascinating development that pushes the boundaries of what’s possible for decentralized, off-grid communication.
