Abstract

Los métodos para un protocolo de cadena de bloques virtual incluyen generar una clave pública y una clave privada para transmitir un mensaje desde un emisor a un destinatario. El emisor encripta el mensaje usando la clave pública y una clave criptográfica del destinatario para generar una primera carga útil de datos. El emisor firma una función de troceo de la primera carga útil de datos usando una clave criptográfica del emisor para generar una segunda carga útil de datos. El emisor transmite la primera carga útil de datos y la segunda carga útil de datos al destinatario. El emisor recibe una versión firmada de la segunda carga útil de datos firmada usando la clave criptográfica del destinatario. El emisor determina que se ha publicado la versión firmada de la segunda carga útil de datos en una cadena de bloques. El emisor publica la clave privada en la cadena de bloques.
