BITCHAT OF THE CO-FOUNDER OF TWITTER WORKS WITH BLUETOOTH
Without SIM, Wi-Fi, and Internet.
Jack Dorsey, the co-founder of former Twitter, now X, is working on a new messaging app that does not rely on the Internet to send and receive messages, but only on Bluetooth.
It's called Bitchat.
Classic Bluetooth does not have a very wide range. To overcome this limitation, Bitchat leverages its "mesh" network. Essentially, with Bitchat, as users move around, their phones form local Bluetooth clusters and transmit messages from one device to another. Even if two users are not within direct range of each other, the message can still reach its destination by passing through intermediate phones.
The purpose of Bitchat is not to replace WhatsApp or Telegram, but it is dedicated to specific needs, such as communicating without being tracked or in particular contexts, such as during blackouts or natural disasters.
Brilliant, right?
