Abstract: A method, a device and a system for certifying a resource contributing to a communication service that can be instantiated in a data infrastructure. The method is carried out in an evaluation entity deployed in the infrastructure. The evaluation entity is associated with at least one parameter of the resource. The method includes receiving, from the resource, a request to certify the at least one parameter of the resource contributing to the service to be instantiated; comparing the at least one parameter contained in the received request with at least one value required to perform the service in the data infrastructure; and transmitting, to the resource, data certifying the resource in the data infrastructure for the service to be instantiated if the at least one parameter is equivalent to the required value.

Abstract: In known implementations of distributed ledgers, all of the transactions linked to a service are archived in nodes involved in the implementation of the service. This makes it possible to verify the authenticity and the integrity of the transactions and to ensure that the service that is provided is compliant. This poses a problem for nodes having limited storage capacities, some ledgers possibly reaching a significant size and ultimately potentially making it impossible for some modes to be able to record new transactions, thus causing a problem in terms of controlling the actual execution of the operations linked to these transactions. The present solution allows some nodes involved in the implementation of a service to be able to empty their local ledgers without this jeopardizing the correct operation of the associated distributed ledger. The transparency and the permanence of the transactions relating to the service are thus guaranteed.
