What is Bitchat? Jack Dorsey's Revolutionary Offline Messaging App
The decentralized messaging app that works without internet, inspired by Bitcoin's principles. Over 1 million downloads and counting.
What is Bitchat?
Bitchat is a peer-to-peer encrypted messaging app developed by Jack Dorsey, co-founder of Twitter (now X) and Block, Inc. Announced in July 2025 as a "weekend experiment," Bitchat enables users to send messages via Bluetooth mesh networks without requiring internet connections, cellular service, or user accounts.
Much like Bitcoin removes reliance on centralized financial intermediaries, Bitchat aims to eliminate central authorities from digital communications. The app has quickly become essential in regions facing internet restrictions or natural disasters.
Bitchat uses Bluetooth Low Energy (BLE) to create mesh networks where messages hop from device to device until they reach their destination - no internet, no phone number, no account needed.
How Does Bitchat Work?
Bitchat Hybrid Architecture
Bluetooth Mesh
Offline Communication
- No internet required
- Hop-by-hop relay between devices
- BLE (Bluetooth Low Energy)
Nostr Protocol
Global Reach
- Internet-based messaging
- Decentralized relay network
- Cryptographic identity
Bitchat seamlessly switches between Bluetooth mesh (offline) and Nostr (online) based on connectivity, ensuring messages always reach their destination.
Bitchat operates on a hybrid architecture with two complementary transport layers. When offline, it uses Bluetooth Low Energy to form mesh networks between nearby devices, relaying messages hop-by-hop. When online, it leverages the Nostr protocol for global reach through decentralized relays. The app seamlessly switches between these modes based on connectivity.
