Block CEO and co-founder of Twitter Jack Dorsey has released a beta version of Bitchat, a decentralized peer-to-peer messaging service that operates entirely through Bluetooth Mesh Networks. The app provides encrypted communication without internet infrastructure, making it resilient to network failures and censorship.
What you need to know:
Bitchat uses Bluetooth Low Energy Mesh Networks with a range of 30 meters to transmit messages between devices.
The system does not require central servers, accounts, or registration and provides ephemeral messaging with end-to-end encryption.
Target use cases include conferences, protests, disaster zones, and scenarios where internet access is unavailable or unreliable.
Dorsey announced the project on Sunday X, stating he spent the weekend studying 'Bluetooth Mesh Networks, relays, storage and forwarding models, message encryption models, and several other things.' He described the system as having 'IRC vibes,' referring to early Internet Relay Chat systems from the late 1990s.
Technical architecture and privacy features
The white paper details the fully decentralized architecture of Bitchat, which eliminates central servers, accounts, email addresses, phone numbers, or reliance on infrastructure. Messages by default exist only in the device's memory and are not stored in any central database. The system provides end-to-end encryption for additional layers of security.
Each device functions as both a client and a peripheral, creating a self-organizing mesh where messages can hop between devices to reach distant peer nodes. Bridge nodes connect individual clusters, extending the network's reach beyond the standard 30-meter Bluetooth range.
The app fragments large messages into 500-byte chunks and uses various encryption methods depending on whether the messages are private, sent to rooms, or broadcast. Room-based chat includes group chats with hashtags and additional password protection. The storage and forwarding system caches messages for offline peers for predetermined periods.
Future plans include the ability to message over Wi-Fi to increase bandwidth for larger messages. This sharply contrasts with current popular messaging apps like WhatsApp and Messenger, which are managed by centralized corporations like Meta that use personal data and message data as products.
Use cases and market context
The system targets several scenarios where traditional internet messaging fails or creates security risks. These include conferences, protests, disaster zones, and any situations where internet infrastructure is unavailable, unreliable, or unstable.
Dorsey's experience in messaging spans his tenure as CEO of Twitter and founding the decentralized social messaging platform Bluesky in 2019. He left the Bluesky board in May 2024 without explanation. His latest project addresses the growing concerns about surveillance and data collection by major messaging platforms.
In April, reports emerged that popular social messaging apps might track users and collect personal information and messages. Dorsey's approach eliminates these privacy issues by completely removing centralized data collection.
Final thoughts
The white paper concludes that Bitchat demonstrates that secure, private messaging is achievable without centralized infrastructure. By combining a mesh Bluetooth network, end-to-end encryption, and privacy-preserving protocols, the system provides resilient communication that functions wherever people gather, regardless of internet availability.
