Abstract: In manufacturing industry chain,the complex business relations are difficult to deal with when traditional block chain is used to construct the block chain model.For this reason,a block graph model was proposed.The original block was decomposed into two parts: business relationship and business data.The relationship model was constructed by the business relationship,and the physical block was constructed by the business data.Then,the corresponding relationship between the vertices in the block graph and the physical blocks was established by the double mapping mechanism.According to the business characteristics of the manufacturing industry chain,the operation mechanism of the manufacturing alliance graph was established,and the framework of the manufacturing alliance graph was built based on the business scenarios of the manufacturing industry.Combined with the Hyperledger Fabric platform,the block graph was verified and the preliminary effect was obtained,which provided a new method and idea for the manufacturing industry chain to break through the bottleneck of business processing and blockchain.

Key words: manufacturing industry chain, block diagram, consensus mechanism, smart contract
