Abstract

Las implementaciones de la descripción incluyen recibir datos de transacción asociados con la transacción, los datos de transacción comprenden: datos representativos de una pluralidad de activos, un primer compromiso que oculta un primer número aleatorio y una cantidad de transacción de la transacción, un segundo compromiso que oculta un segundo número aleatorio y un cambio, la cantidad de transacción y un tercer número aleatorio ambos cifrados por una clave pública del segundo nodo con base en un esquema de cifrado homomórfico, determinista, lineal (HE), el cambio y un cuarto número aleatorio ambos cifrados por una clave pública del primer nodo con base en el esquema de HE determinista lineal, y un comprobante de conocimiento cero (ZKP); determinar, con base en el ZKP, si la transacción es válida con base en la determinación si el primer número aleatorio es igual al tercer número aleatorio, el segundo número aleatorio es igual al cuarto número aleatorio y la cantidad de transacción oculta en el primer compromiso es igual a la cantidad de transacción cifrada por la clave pública del segundo nodo.
