Twitter co-founder introduces new messaging app named Bitchat

In the digital age, the importance of secure and private communication has never been more prominent. Enter Bitchat, a new mobile messaging app launched by Jack Dorsey, co-founder of Twitter and Block, on July 8, 2025. The app, available for download on the App Store and Android via GitHub, promises to revolutionize offline communication, especially in situations where traditional methods fail.

Bitchat operates on a peer-to-peer, end-to-end encrypted messaging system, making it an attractive choice for those seeking privacy and security. Unlike other messaging apps, Bitchat does not rely on central servers or internet connections. Instead, it uses Bluetooth Mesh networking to pass messages device-to-device, ensuring that messages never get stored indefinitely or touch centralized infrastructure.

Key features of Bitchat include:

End-to-end encryption: Messages are encrypted so only the sender and recipient can read them, providing protection from eavesdropping, even on mesh relays.
No data collection or accounts: Users do not create identifiable accounts, and Bitchat collects no user data, reducing risks of surveillance or tracking.
Decentralized mesh networking: Because it uses Bluetooth mesh to relay messages directly among nearby devices, there is no reliance on cellular or Wi-Fi networks that could be shut down or monitored.
Open-source design: Bitchat’s code is publicly available for inspection, enabling independent security researchers to find and report vulnerabilities.

However, it's important to note that Bitchat has not yet undergone a formal external security audit, and users should exercise caution when using the app for sensitive communications. Security researchers have identified potential vulnerabilities such as ease of impersonation, which Dorsey partially addressed by implementing the Noise Protocol Framework to improve encryption and authentication.

Given its experimental status and lack of comprehensive security audits, users should remain cautious and not rely on Bitchat yet for highly sensitive or critical communications. Nevertheless, the app has sparked interest among users due to its concept and technological features, especially given the growing demand for decentralized and offline communication tools.

In localized communication scenarios, Bitchat proves to be a powerful tool. It allows users to exchange messages with others within a 100-meter radius, regardless of mobile connectivity or Wi-Fi. This feature has been praised by experts, with Alex Radoch stating that it's "very easy to impersonate someone else" in the Bitchat program. However, this potential vulnerability should be addressed in future updates to ensure the app's security.

Bitchat's minimalistic interface takes users directly to the messaging window upon opening, making it user-friendly and accessible. The app has already gained popularity, with users downloading it on iOS devices from the App Store and Android devices from GitHub. It has even been used by activists during protests, demonstrating its potential as a powerful tool for offline communication.

In conclusion, Bitchat offers a promising solution for privacy and security in offline communication. While it's still an experimental app, its strong encryption, decentralized peer-to-peer networking, and minimal data collection make it an attractive choice for those seeking privacy and resistance to censorship. However, users should remain cautious and await comprehensive security audits before relying on it for sensitive communications.
