Elon Musk lanza la mensajería XChat "al estilo bitcóin" y la Red estalla en críticas

"Puedes realizar llamadas de audio/video sin necesidad de un número de teléfono en todas las plataformas", destacó el magnate.

Elon Musk anunció este domingo el lanzamiento de la plataforma de mensajería XChat, una de cuyas características clave es el cifrado de datos "al estilo de bitcóin".

"El nuevo XChat se lanza con cifrado, mensajes que desaparecen y la posibilidad de enviar cualquier tipo de archivo. Además, llamadas de audio y video", escribió el magnate en su red social X. Asimismo, señaló que el sistema está construido con el lenguaje de programación Rust y "una arquitectura completamente nueva", sin presentar más detalles técnicos. "Puedes realizar llamadas de audio/vídeo sin necesidad de un número de teléfono en todas las plataformas", destacó.

Sin embargo, la comunidad criptográfica no está especialmente entusiasmada, expresando dudas sobre el aspecto tecnológico de la aplicación. "Bitcóin ni siquiera utiliza cifrado", respondió a la publicación el criptoexperto Luke Dashjr. Además, expresó que Rust es de la agenda 'woke', debido principalmente a "la cultura que lo rodea", y enfatizó que "también es una mala idea por motivos de seguridad". Samson Mow, experto en bitcóin y director ejecutivo de JAN3, también indicó que la criptomoneda no está encriptada.

"En serio, ¿qué es el cifrado al estilo bitcóin? Bitcóin utiliza principalmente firmas, no cifrado. Es como decir que hemos decidido propulsar nuestro cohete con agua, ya que la NASA utiliza hidrógeno y oxígeno", tuiteó Ian Miers, profesor adjunto de Informática en la Universidad de Maryland. "No hace falta decir que 'estilo bitcóin' y 'Rust' no son descripciones de un esquema de cifrado, ni son indicadores sólidos de la seguridad de una aplicación de mensajería. Además, a menos que los mensajes directos cifrados solo estén en la aplicación, lo más probable es que no estén solo en Rust", añadió.

Mientras, el portal CoinDesk explicó que el cifrado implica convertir información en un formato que solo quienes poseen las claves adecuadas pueden interpretar. A diferencia de esto, las operaciones realizadas en la 'blockchain' de bitcóin son firmadas en lugar de estar cifradas. En realidad, la información intercambiada entre los nodos de la criptomoneda no está protegida por cifrado, lo que facilita que individuos ajenos puedan participar en la red.
