Xchat is likely to use some type of elliptical curve cryptography (ECC).

Bitcoin uses ECDSA, an elliptical curve focused on digital firms.
Elon Musk, the current CEO of X, announced a series of novelties in Xchat, the social network messaging function. Among other improvements, the chat uses end -to -end encryption, such as Telegram, and is capable of transmitting video calls, erase messages (vanishing mode), Allow group chat and load attachments. But the most interesting novelty announced by Musk is that XChat is built on Rust, the programming language, and inspired by Bitcoin. «It is built on Rust with encryption (bitcoin style), a completely new architecture.» The Tesla CEO commented.
XChat is a new messaging function that began to be implemented in the social network X, although for now it is in the beta phase. Its purpose is to improve and strengthen the system that currently exists, which works by sending direct messages («DM»).
Only some X users, those who pay for the subscription of the platform, can access Xcat currently, although certain information indicates that an encrypted version of direct messages has exists in X for two years. Nevertheless, Xchat, the new system, would be close to being launched definitively. This was reported by Nima Owji, an independent applications.
While Musk does not explain what he refers to with an «bitcoin» encryption, it is possible that Xchat uses an encryption method similar to the one that works in the cryptoactive protocol. Bitcoin uses elliptical curve cryptography (ECC), specifically a version for digital signatures called ECDSA, which means in Spanish «digital signature algorithm of elliptical curve.»
Since messaging applications As WhatsApp and Signal they use ECC methodsXchat is likely to use a similar solution for messing of messages. This implies that XChat, like these applications, uses public and private key based on elliptical curves to encrypt messages from end to extreme, ensuring that only participants can read them.
At the time of writing, it is not yet detailed what elliptical curve uses XChat. For example, Curve25519 or FHMQV? Nor is it known how private keys are managed (are they locally stored in the user’s device or is there a key server involved?).
