Jack Dorsey launched Bitchat, a chat app designed for secure and private messaging using Bluetooth and end-to-end encryption, avoiding centralized infrastructure. It aims to be effective in high-risk environments where internet connectivity is compromised.

Dorsey has since added disclaimers on GitHub, warning users against relying on Bitchat for secure communications until reviewed. Additionally, vulnerabilities found in its identity authentication allow for possible impersonation of users.
