Jack Dorsey just released a decentralized, peer-to-peer messaging app that functions entirely over Bluetooth networks, as reported by CNBC. It's called Bitchat and doesn't need the internet to work, as there are no central servers.The Twitter co-founder calls it an experiment in "Bluetooth mesh networks, relays and store and forward models, message encryption models and a few other things." It works by enabling encrypted communication between nearby gadgets. Basically, it sends messages directly from one device to another, but each device is also a node that widens the network a little bit.

Earlier this month, Block CEO and Twitter co-founder Jack Dorsey unveiled a peer-to-peer, Bluetooth-based messaging app he put together. Now, anyone with a compatible iPhone, Mac or iPad (or even Apple Vision Pro) can try Bitchat as it's available on the App Store.Dorsey created Bitchat under the auspices of "and Other Stuff," an open-source development collective he has backed financially. Per the free app's description, it allows users to chat with others who are physically close to them without needing to have their email address or phone number, which could make Bitchat handy for in-person events. Messages are private and encrypted, while the Panic Mode function allows you to delete all your Bitchat data with a triple tap.Dorsey said he built Bitchat as an experiment in "Bluetooth mesh networks, relays and store and forward models, message encryption models and a few other things." The app doesn't need internet access to function, making it a useful option in situations in which authorities block mobile data and Wi-Fi connectivity. Other apps that offer Bluetooth mesh messaging first started appearing over a decade ago.
