Elon Musk announced the upcoming feature "X Chat" for his social media platform, X, during his appearance on the "Joe Rogan Experience." This new messaging service will utilize a peer-to-peer encryption model similar to Bitcoin and is designed to enhance security by minimizing vulnerabilities compared to other messaging applications. X Chat will not include advertising hooks, focusing instead on user privacy and security. A standalone app is also planned for release in a few months, allowing users to send messages, share files, and make audio or video calls. The in-app chat will support various media linked to X handles rather than phone numbers.
