Twitter co-founder and Block CEO Jack Dorsey has begun testing Bitchat, a new decentralized messaging app designed to function without the internet. 

Bitchat operates over a Bluetooth Low Energy (BLE) mesh network, enabling users to send ephemeral, encrypted messages fully offline. 

This story is an excerpt from the Unchained Daily newsletter.

The system is built to be censorship-resistant and to function even during network outages or in disconnected environments, Dorsey explained in a whitepaper.

It will also support ephemeral messaging, meaning messages are temporary and not stored permanently.

“It’s almost like this guy has some experience building decentralized peer to peer networks..,” commented tech entrepreneur and Neosync founder Evis Drenova.
