Abstract

Implementaciones de la presente descripción incluyen recibir, de una primera cuenta, una copia digitalmente firmada de una pluralidad de notas, un compromiso de una cantidad de transacción de una transacción entre la primera cuenta y una segunda cuenta pagada por al menos una porción de la pluralidad de notas, un compromiso de un cambio de deducir la cantidad de transacción de un valor total de la pluralidad de notas, y una prueba de conocimiento cero generada con base en uno o más números aleatorios seleccionados. La primera cuenta determina que el valor total de la pluralidad de notas equivale a la suma de la cantidad de transacción y el cambio, valida la transacción, y actualiza la primera cuenta y la segunda cuenta con base en la pluralidad de notas, la cantidad de transacción, y el cambio.
