The request being associated by a selected fee quote and/or service level associated with the selected fee quote among the received fee quotes in the above aspect. In a third aspect the method includes creating, processing and mining a blockchain transaction associated with a client by a miner, based on the miner satisfying the selected fee quote from the client, as mentioned in the above aspect.
