1. A method performed by a network node of a service management system, the method comprising:
receiving, from a service installer, a first signed message including a request to authorize installation of a service image, a service image identifier, a service installer account identifier, and one or more hashes of the service image; and
responsive to determining, based on the service installer account identifier and a distributed ledger, that the service installer is authorized to install a service image identified with the service image identifier in a cloud computing system, performing the following:
recording the one or more hashes of the service image in a list of valid service images of the distributed ledger, and
transmitting, to the service installer, a first message including a first service installation token and the service image identifier, wherein the first service installation token causes the service installer to install the service image in the cloud computing system.
