Abstract

Las implementaciones de la presente descripción incluyen recibir, por un nodo de consenso de una primera cuenta, una copia digitalmente firmada de un valor de compromiso de una cantidad de transacción, un segundo número aleatorio cifrado usando una clave pública de la primera cuenta, un tercer número aleatorio cifrado usando una clave pública de la segunda cuenta, una o más pruebas de intervalo, y un conjunto de valores generado con base en uno o más números aleatorios seleccionados. El nodo de consenso entonces verifica una firma digital que corresponde a la copia digitalmente firmada usando una clave pública de la primera cuenta que corresponde a una clave privada usada para generar la firma digital. También actualiza el saldo de la primera cuenta y un saldo de la segunda cuenta con base en la cantidad de la transferencia de saldo si el primer número aleatorio, el segundo número aleatorio, y el tercer número aleatorio son el mismo.
