Master-Slave Multi-Chain Consensus Mechanism of Consortium Blockchain Based on Hypergraph and MuSig2
摘要
Abstract
To solve the problems of multi-chain blockchain using the final consensus mechanism of the main block-chain,resulting in a large load on the main blockchain and restricting the performance of the slave blockchain,a master-slave multi-chain consensus mechanism of the consortium blockchain based on hypergraph and MuSig2 aggregate signature is proposed.Firstly,according to the hypergraph theory,a master-slave multi-chain architecture of the consortium block-chain with the transverse hypergraph as the main blockchain and the sub-hypergraph as the slave blockchain is constructed.Then,drawing on the divide and conquer ideology,combined with the consensus mode of"endorsement-sorting-verifica-tion",a hierarchical classification consensus mechanism is constructed to reduce the load pressure of the main chain through classification processing transactions.Finally,a multi-party endorsement signature method based on MuSig2 aggre-gate signature is constructed to improve the verification efficiency and performance of endorsement signatures.Performance analysis shows that the multi-party endorsement signature of the consortium blockchain based on MuSig2 aggregate signa-ture is safe and reliable,and the hierarchical classification consensus mechanism based on hypergraph and MuSig2 aggre-gate signature has strong consistency and linear time complexity.Experimental result shows that the total efficiency of the multi-party endorsement method based on MuSig2 aggregate signature is 1.55 times that of elliptic curve digital signature algorithm(ECDSA),and the hierarchical classification consensus mechanism can improve the consensus efficiency by 12.5%.This mechanism has high performance and can meet the diversified business needs of enterprises.关键词
