Research on data sharing mechanism of power material supply chain based on blockchain

Aiming at the common problems of data centralized storage, poor security and weak tamper resistance in the existing power material supply chain management, a data sharing mechanism based on block chain is proposed: the power limit setting and identity authentication of power material supply chains at all levels are realized through joint consensus algorithm and digital signature; Through the interstellar file system (IPFS) technology in the blockchain, data protection, verification, recovery and sharing are realized. Finally, through experimental comparison, this method has the characteristics of decentralization, security, credibility and non-tampering. It not only reduces the overall inventory cost of the supply chain, but also ensures the security of data and improves the overall response speed of the supply chain.
