Bitchat is a new experimental messaging app developed in 2025 by Jack Dorsey (co-founder of Twitter/X and Block, Inc.). Unlike WhatsApp or other mainstream messengers, it works without internet, SIM cards, or servers. Instead, it uses Bluetooth mesh networking to send encrypted messages between nearby devices.
How Does Bitchat Work?
- Bluetooth Mesh Messaging: Messages travel from one phone to another using Bluetooth, creating a network of connected devices. Range can extend up to 300+ meters depending on how many users are nearby.
- End-to-End Encryption: Strong encryption ensures chats remain private and secure.
- No Accounts Required: No phone numbers, emails, or personal details are needed. You simply choose a display name.
- Privacy Features: Password-protected chatrooms, panic mode to instantly delete chats, and even dummy messages for extra anonymity.
- No Servers: Fully decentralized; no data stored on central servers.

Final Awareness Note
