Abstract
Methods and systems for authorizing the access of a service are described. A server is operative to receive a request to subscribe to a service. The server is to receive from the requestor a selected service offer from the set of service offers, where the selected service offer is cryptographically signed with the private key of the requestor and the private key of the service. The server is further to record a delegation contract into a blockchain database, where the delegation contract includes an identification of the service, an identification of the requestor, and the service offer that is cryptographically signed with the private keys of the requestor and the service. The server is to transmit, to the requestor, a confirmation that the service can be accessed based on the selected service offer; and transmit to the service the delegation contract causing the service to provide access to the requestor.
