**Bitchat: Bluetooth Messaging Application Without Internet from Jack Dorsey**
Jack Dorsey, the founder of Twitter and Square, recently launched a new messaging application called **Bitchat**. This application allows users to send messages directly between devices using **Bluetooth mesh** technology without needing an internet connection.
Bitchat features **end-to-end encryption** to maintain message privacy and uses a multi-hop relay system, allowing messages to be forwarded through other devices to extend communication range to about 300 meters. Additionally, this application does not require a phone number, email, or central account, making it truly decentralized and censorship-free.
Messages sent are temporary and only stored in the device's memory, enhancing user data security. Bitchat also supports hashtag-based group chats with password protection options, suitable for community or small group communication without relying on the internet network.
With Bitchat, Jack Dorsey offers a secure, private, and independent communication solution, ideal for situations without internet access or for avoiding digital surveillance.
