Jack Dorsey’s Bitchat: A Decentralized Messaging App

Jack Dorsey, the visionary co-founder of Twitter (now X), is no stranger to shaking up the tech world. His latest endeavor, Bitchat, is a bold step into the realm of decentralized, peer-to-peer messaging that operates entirely over Bluetooth mesh networks, requiring no internet, central servers, or personal identifiers. Launched as a beta on Apple’s TestFlight platform in July 2025, Bitchat has already garnered significant attention, hitting its 10,000-user cap shortly after its announcement. Let’s dive into what makes Bitchat a potential game-changer for privacy-focused communication and explore its features, use cases, and implications for the future.

What is Bitchat?

Bitchat is a messaging app that allows users to communicate without Wi-Fi or cellular service, leveraging Bluetooth Low Energy (BLE) mesh networks. Unlike traditional apps like WhatsApp or Telegram, which rely on centralized servers and user accounts, Bitchat operates on a decentralized model. Messages are sent directly from one device to another, forming local Bluetooth clusters that can relay messages across greater distances—up to 300 meters (984 feet)—through a process called mesh routing. This makes it ideal for scenarios where internet access is unreliable, restricted, or nonexistent.

Dorsey described Bitchat as a “weekend project” to explore Bluetooth mesh networks, message encryption, and store-and-forward models, giving it “IRC vibes” reminiscent of the 36-year-old Internet Relay Chat system. The app supports both topic-based group chats (or “rooms”) with optional password protection and encrypted private messaging, ensuring privacy and security without the need for phone numbers or email addresses.

Key Features of Bitchat

• Offline Communication: Bitchat operates without internet or cellular networks, using Bluetooth to connect nearby devices. Messages can hop from one device to another, extending the range beyond the standard Bluetooth limit of about 30 meters.
• End-to-End Encryption: All messages, whether private or in group chats, are encrypted, prioritizing user privacy.
• No Personal Identifiers: Users don’t need to provide phone numbers, emails, or any personal information, ensuring anonymity. Random peer IDs are generated for each session.
• Group Chats and Rooms: Users can create hashtag-named group chats with optional password protection for secure, topic-based conversations.
• Store-and-Forward Messaging: Messages for offline users are cached on nearby devices and delivered when the recipient reconnects.
• Platform-Agnostic Potential: While currently in beta on iOS via TestFlight, the protocol is designed to support Android development in the future.
• Future Wi-Fi Direct Support: Dorsey plans to integrate Wi-Fi Direct to enhance speed and range, potentially enabling richer content sharing like images and videos.

Why Bitchat Matters

Bitchat’s decentralized, internet-free design makes it a powerful tool for specific scenarios:

• Censorship Resistance: Similar apps like FireChat and Bridgefy gained traction during the 2019 Hong Kong protests, allowing users to communicate despite government-imposed internet blackouts. Bitchat could serve similar purposes in regions with heavy censorship or surveillance.
• Event and Disaster Use Cases: From music festivals with spotty cell service to natural disasters where infrastructure fails, Bitchat enables communication in challenging environments.
• Privacy Advocacy: With no servers, no data collection, and end-to-end encryption, Bitchat aligns with Dorsey’s long-standing push for decentralized, user-controlled technology, as seen in his work with Bitcoin and Bluesky.

However, Bitchat isn’t without challenges. Critics have raised concerns about its security, noting that the app’s authentication system may be vulnerable to interception by malicious actors. Dorsey has acknowledged these issues, adding a disclaimer that the software “has not received external security review and may contain vulnerabilities.” Additionally, Bluetooth’s limited range (typically 30-100 meters without relays) and potential for spam in open mesh networks could pose scalability issues.

The Bigger Picture

Bitchat reflects Dorsey’s ongoing commitment to decentralizing technology and championing free expression. His previous ventures, like Bluesky (a decentralized social network) and his support for Nostr, show a consistent focus on giving users control over their data and communications. As the CEO of Block Inc., which powers financial services like Square and holds significant Bitcoin assets, Dorsey is also exploring intersections between decentralized messaging and cryptocurrency. Posts on X suggest users have already started sending Bitcoin via Bitchat, storing transactions offline until they can be broadcast to the Bitcoin network.

While Bitchat remains an experimental project, its implications are significant. In a world where online censorship and internet shutdowns are increasingly common, tools like Bitchat could empower users to communicate freely and securely. The app’s open-source nature, with its code and whitepaper available on GitHub, invites community contributions to improve its security and functionality.

What’s Next for Bitchat?

Currently in beta and limited to 10,000 iOS testers, Bitchat is still under review for a full App Store release. Dorsey and his team are working on battery optimization, relay stability, and an Android version. The planned Wi-Fi Direct integration could make Bitchat even more versatile, supporting faster data transfer and broader network reach.

As Dorsey continues to refine Bitchat, its success will depend on addressing security concerns, scaling the mesh network, and navigating potential regulatory hurdles in regions wary of decentralized communication tools. For now, Bitchat stands as a fascinating experiment in offline, privacy-first messaging—one that could inspire larger platforms to rethink how they approach user privacy and resilience.
