Elon Musk officially announced the rollout of XChat, a revamped direct messaging platform for X, featuring vanishing messages, file sharing, and integrated audio and video calling capabilities. The platform, which is currently transitioning from a limited beta phase, is expected to reach all global users within the week, provided no major infrastructure scaling issues arise.
Architecture and Security Claims
Musk stated that the updated XChat architecture is built on the Rust programming language and utilizes what he describes as “Bitcoin-style” encryption. However, this terminology has triggered immediate pushback from the cybersecurity community. Technical experts point out that Bitcoin relies on public key cryptography and digital signatures, rather than traditional encryption protocols used for private messaging, leading many to question whether the term was used for marketing purposes or due to a fundamental misunderstanding of cryptographic principles.
The confusion has ignited a widespread debate across social media and tech forums. Critics are questioning the actual security posture of the new system, especially as Musk has long positioned X as a direct competitor to privacy-focused platforms like Signal and iMessage.
New Features and Platform Stability
Beyond the encryption controversy, the update introduces the ability for users to initiate audio and video calls across all devices without the requirement of a linked phone number. This shift follows the company’s decision to pause previous iterations of encrypted DMs, effectively signaling that XChat is intended to serve as the unified replacement for the platform’s messaging infrastructure.
Despite the ambitious rollout, the timing remains precarious. X has experienced significant instability over the past week, with multiple outages hindering timeline access and core service functionality. Whether the team can maintain system uptime while integrating this complex new architecture remains the primary challenge for the platform moving forward.
