Aiming to solve the queuing delay problem of the blockchain in the cloud manufacturing system, and explore factors that reduce the queuing delay of the blockchain in the cloud manufacturing system, this paper proposes a new type of cloud manufacturing system blockchain model. The blockchain services are introduced into the service layer of the traditional cloud manufacturing system architecture. The queuing delay process of manufacturing service requests in the blockchain service is decomposed into the buffer phase and the consensus phase, and the M/M/1 queuing model is used to analyze system indicators. An adaptive difficulty value mechanism is proposed to optimize the chances of nodes with different computing powers to participate in consensus. And the relationship between node revenue and node service rate is studied. The simulation results show that the M/M/1 queue model can reflect the request queuing delay process of the cloud manufacturing system. After the introduction of the adaptive difficulty value, the blockchain node with small computing power has a greater chance to obtain the bookkeeping right, and the node’s revenue is positively correlated with its service rate.
