Jakarta, INTI – The tech world is once again surprised by an innovative move from Jack Dorsey, founder of X (formerly Twitter), who introduced a new messaging app called BitChat. Unlike mainstream chat applications like WhatsApp or Telegram, BitChat brings a bold concept: it operates without internet or phone numbers.
Dorsey unveiled BitChat through his X account on the evening of Sunday, July 6, 2025, accompanied by a white paper detailing the technical framework of the app. This launch underscores Dorsey’s commitment to building a more decentralized communication and social media ecosystem, following his earlier project, Bluesky.
What is BitChat?
BitChat is a messaging app that uses peer-to-peer mesh Bluetooth networks instead of relying on the internet. This makes BitChat highly useful in areas with weak signals or no internet access at all.
Unlike WhatsApp, which requires central servers and phone numbers for account registration, BitChat does not depend on servers, accounts, emails, or phone numbers. All communication is done directly between users via Bluetooth, offering more privacy and control.
How BitChat Works: Bluetooth Mesh Network
BitChat leverages mesh Bluetooth technology, where each connected device acts as a signal extender. Through this setup, messages can travel from one device to another until they reach the intended recipient.
Although Bluetooth normally works within a 10-meter range, the mesh network allows BitChat to cover a much broader area, potentially over 300 meters, depending on how many devices are nearby and how close they are to each other.
Security and Key Features
Beyond its independence from the internet, BitChat emphasizes data security. All messages are protected with end-to-end encryption using Curve25519 and AES-GCM technologies, ensuring that messages remain private and cannot be intercepted by third parties.
Other notable features of BitChat include:
- Local message storage (not saved on any central server)
- Group chats
- Mentions using usernames
- Favorites to bookmark important messages
- Rooms and Password Rooms for private conversations
Is BitChat Publicly Available?
Currently, BitChat is still in its beta testing phase, available only on iOS through Apple’s TestFlight program. This trial phase has already reached its maximum capacity of 10,000 users.
Dorsey has not yet confirmed whether BitChat will be made available for Android or other platforms. However, considering the public's interest, a broader release is likely on the horizon.
A Lifeline in Emergency Situations
BitChat is not just an alternative to WhatsApp it’s also a lifeline in emergencies, such as during natural disasters or internet blackouts enforced by authorities. Its offline capability makes it possible to communicate when traditional networks are down.
Conclusion
BitChat is a testament to the ongoing innovation in the world of communication. With its decentralized structure, strong encryption, and independence from internet or phone numbers, BitChat may pave the way for a new generation of messaging apps. Time will tell whether it can truly challenge the dominance of WhatsApp and Telegram.
