Hyperledger Fabric并发冲突消除机制
Concurrency conflict elimination mechanism for Hyperledger Fabric
摘要
Abstract
Hyperledger Fabric is a mainstream consortium blockchain platform.When facing multiple concurrent transactions that are interrelated,the existing architecture tends to generate a large number of invalid transactions,which severely reduces the system's effective transaction processing capability.To address this issue,this paper proposed a conflict elimination mecha-nism that integrated map and directed acyclic graph(DAG),known as the FabricIMD(Fabric integrated with map and DAG)mechanism.The mechanism identified dependencies between transactions at the peer node(endorser)through map and con-structed these relationships using a directed acyclic graph to adjust the endorsement order of transactions,thereby effectively a-voiding transaction conflicts.Experiments demonstrate that when there are multiple interrelated concurrent transactions,Fab-ricIMD mechanism can significantly reduce invalid transactions caused by transaction conflicts.With varying degrees of conflict among transactions,the system's effective transaction throughput increased by 15.68％to 96.08％.Moreover,when dealing with unrelated concurrent transactions,the introduction of this mechanism did not significantly impact system perfor-mance.In summary,FabricIMD mechanism not only avoids transaction conflicts but also enhances the system's effective transaction throughout and significantly reduces the number of invalid transactions.关键词
