Elon Musk announces new feature "XChat" to enhance privacy with Bitcoin-like encryption.

## New feature "XChat" announced

Elon Musk announced the release of "XChat" on his X on the 2nd. The newly added features include end-to-end encryption, message self-destruction, file sharing of any kind, and voice and video calls.

"A completely new XChat will be released. It features encryption, message disappearance functionality, the ability to send all kinds of files, and voice/video calls. Built on a brand new architecture based on Rust, it adopts Bitcoin-style encryption. Additionally, voice and video calls are possible on all platforms without a phone number." Source: Elon Musk

Mr. Musk explained that these features are designed based on Rust, referencing "Bitcoin-style encryption." This does not simply mean that the technology of Bitcoin itself has been implemented, but rather that the tamper resistance and self-sovereign security principles of Bitcoin have been applied to XChat's messaging.

This background includes the increasing risks of personal information leakage and surveillance, as well as the rising awareness of user privacy. Disappearing messages and encryption features are attractive elements for users who want to conduct highly confidential conversations and exchanges of personal information more safely. Additionally, the support for voice and video calls and the ability to send various files suggests an intention to evolve XChat from a mere messaging app into a "universal tool that supports work and life."

XChat can be said to be aiming for a position as a "next-generation messaging service" centered around privacy protection, not just as a mere feature addition. It differentiates itself from competing services like Signal, Telegram, and WeChat, and supports the plan to evolve X into an "everything app."
