The new messaging application called "BitChat," developed by Jack Dorsey, co-founder of Twitter. This platform is designed to operate without an internet connection, using Bluetooth mesh networks for direct, decentralized, and encrypted peer-to-peer communication. Dorsey announced the application on his "X" account, emphasizing its resilience to outages and censorship, and comparing its mechanism to the old IRC protocol. The app has been well-received, particularly by cryptocurrency experts who note its capability to send digital currencies via Bluetooth, leading some to call it a "WhatsApp killer." BitChat's beta invitations were quickly claimed after its announcement.
