Abstract

En un sistema de transacción en el que las transacciones se organizan en bloques, se construye un nuevo bloque Br de transacciones válidas, en relación con una secuencia de bloques anteriores B0, B1, ..., Br ~ 1, haciendo que una entidad determine una cantidad Q de los bloques anteriores, haciendo que la entidad use una clave secreta para calcular una cadena S asociada únicamente a Q y a la entidad, haciendo que la entidad calcule a partir de S una cantidad T que es S, una función de S, o un valor hash de S, haciendo que la entidad determine si T posee una propiedad dada y, si T posee la propiedad dada, haciendo que la entidad firme digitalmente Br y ponga a disposición S y una versión firmada digitalmente de Br, en donde la entidad se selecciona con base en un valor aleatorio que varía de acuerdo con una firma digital de Br.
