Jack Dorsey Launches Decentralized Bitchat Messaging App

Jack Dorsey, co-founder of Twitter and Block, has launched Bitchat, a decentralized messaging app now available on the Apple App Store. The app enables encrypted, peer-to-peer Bluetooth mesh messaging without internet, user accounts, phone numbers, or central servers, and features rapid data deletion via 'Panic Mode.' Messages are stored only on devices and deleted soon after delivery, emphasizing privacy and security. Bitchat is especially useful in areas with limited connectivity, such as protests, disaster zones, or large events. However, external security experts have yet to review the app, and impersonation vulnerabilities have been flagged. The launch coincides with Block’s recent inclusion in the S&P 500, underscoring the increasing mainstream adoption of crypto and decentralized technologies.
