Jack Dorsey Launches Bitchat: A New Way to Message Without the Internet

Jack Dorsey Launches Bitchat: A New Way to Message Without the Internet

July 9, 2025 – Jack Dorsey, co-founder of Twitter and CEO of Block, has introduced Bitchat, a groundbreaking peer-to-peer messaging app that works without an internet connection. Announced on July 6, 2025, as a personal “weekend project,” Bitchat uses Bluetooth mesh networks to enable secure, private communication, even in areas with no Wi-Fi or cellular service. The app, now in beta testing, is designed to prioritize user privacy, decentralization, and resistance to censorship.

What is Bitchat?

Bitchat allows users to send encrypted messages directly between devices using Bluetooth Low Energy (BLE) mesh networks. Unlike traditional messaging apps like WhatsApp or Telegram, Bitchat does not rely on central servers, phone numbers, or email addresses. This makes it ideal for situations where internet access is unavailable, unreliable, or blocked, such as during protests, natural disasters, or in regions with heavy surveillance.

The app creates a self-organizing network where each device acts as both a sender and a relay, passing messages to nearby devices within a 30-meter range. These messages can “hop” across multiple devices to reach users farther away, extending the network’s reach. For example, in a crowded event or a remote area, Bitchat can keep people connected without any internet infrastructure.

Key Features of Bitchat

– No Internet Required: Messages are sent via Bluetooth, making Bitchat functional even during internet blackouts or in areas with no connectivity.
– End-to-End Encryption: All messages are encrypted, ensuring only the sender and recipient can read them.
– No Accounts or Personal Data: Users don’t need to sign up with a phone number or email, reducing the risk of data collection or tracking.
– Ephemeral Messages: Messages are stored only temporarily on devices, not on central servers, minimizing the chance of data breaches.
– Group Chats: Users can create hashtag-named “rooms” for group discussions, with optional password protection for added security.
– Store-and-Forward System: Messages for offline users are held by nearby devices and delivered when the recipient comes online.

Dorsey shared the project on X, describing it as an experiment in “Bluetooth mesh networks, relays, store-and-forward models, and message encryption.” He also published a whitepaper on GitHub, outlining Bitchat’s technical details and inviting developers to contribute.

Why Bitchat Matters

Bitchat is built for privacy and resilience. By eliminating central servers, it reduces the risk of surveillance, censorship, or data leaks by governments or corporations. This design echoes tools like Bridgefy and FireChat, used during the 2019 Hong Kong protests to bypass internet shutdowns. However, Bitchat’s focus on encryption and simplicity, combined with Dorsey’s influence, could make it more accessible to a global audience.

Dorsey, a long-time advocate for decentralization, has supported projects like Bluesky and Bitcoin, which aim to give users more control over their data and communication. Bitchat continues this mission, offering a tool for secure, independent messaging in challenging environments.

Current Status and Future Plans

Bitchat is currently available for beta testing on Apple’s TestFlight platform, though its 10,000-user limit was quickly reached after Dorsey’s announcement. The app is open-source, with its code and whitepaper available on GitHub for developers to review and improve. Dorsey has hinted at future updates, including Wi-Fi Direct support to increase speed and range, which could allow for sharing larger files like photos or videos.

While still in its early stages, Bitchat has sparked interest among privacy advocates, tech enthusiasts, and those in regions with limited internet access. Its success will depend on user adoption and how well it performs in real-world scenarios like protests, festivals, or disaster zones.

A Step Toward a Decentralized Future

Bitchat represents a bold step toward reimagining how people communicate in a world increasingly concerned with privacy and censorship. By leveraging Bluetooth mesh networks, it offers a practical solution for staying connected without relying on Big Tech or government-controlled infrastructure. As Dorsey wrote on X, Bitchat has “IRC vibes,” harking back to the early days of internet chat while embracing modern security and decentralization.

For now, Bitchat is an experimental project, but its potential to empower users in challenging environments is clear. As the app evolves, it could redefine secure, private messaging for a global audience.
