| Summary: | In cloud manufacturing platform, virtual manufacturing resources have difficulty to guarantee the authen-ticity and security of transaction data in the process of transaction, and have dependency on the unified deployment of cloud manufacturing platform operators (CPO). The centralized framework is prone to single point of failure and the risk of privacy data leakage. In view of these problems, combined with the advantages of decentralization and tamper-proofing of blockchain, the application of blockchain technology in cloud manufacturing is innovatively ex-plored, and a resource allocation method of cloud manufacturing based on blockchain is proposed. Firstly, a decen-tralized cloud manufacturing trading platform framework based on blockchain is proposed, the elliptic curve digital signature algorithm (ECDSA) in the process of manufacturing resource/demand issuance is studied, and the mech-anism of matching between manufacturing resources and manufacturing demand is analyzed. Then, the manu-facturing resource verification contract and manufacturing resource trading contract for cloud manufacturing are designed with the smart contract (SC), and the experimental test on the Remix platform is completed with Solidity. The test results show that the proposed method can provide a secure and reliable guarantee for virtual manufacturing resource trading. Finally, the game problem of supply and demand balance of manufacturing resource suppliers (MRS) and manufacturing resource demanders (MRD) is explored in the decentralized architecture, and the simu-lation is carried out on MATLABR2019b. The simulation results show that the game of manufacturing resource suppliers and manufacturing resource demanders can reach Nash equilibrium, and the convergence speed is faster than the existing research.
