Abstract
Implementaciones de la presente descripción proveen la administración de claves de servicio para redes de cadena de bloques de consorcio dentro de una plataforma de cadena de bloques-como-un-servicio (BaaS). Las implementaciones incluyen acciones para recibir una petición de una clave de servicio de un participante en una red de cadena de bloques de consorcio provista dentro de la plataforma BaaS, determinar que el participante está autorizado para la clave de servicio en base a una tabla de autorización de servicio que registra privilegios de participantes dentro de la red de cadena de bloques de consorcio, proveer un paquete de claves que incluye una clave privada cifrada de la clave de servicio y una clave pública de la clave de servicio y enviar el paquete de claves al participante, el participante descifra la clave privada de la clave de servicio usando una clave pública asociada con el participante.
