Abstract：Toaddress theissuesof insuffcientthroughput，poorliveness，andhighvalidationoverheadinexistingrelaychain cross-chain schemes for cloud-edge-endarchitectures，this paper proposeda dynamic multi-relaychainscheme namedMultiRelay.Firstly，thesheme employed multiplerelaychainsandadynamic transactionalocationstrategytoprocess cross-chain transactionsinparalel，whichnhancedoverall systemthroughput.Secondlyitproposedanon-interactiverandomodeselectionmethodtoimprovethelivenessof thecross-chain processFinally，thesheme proposedacro-chainvalidationmethodbasdontheRSAacumulatortoreduceon-chainvalidationoverhead.Experimentalresultsdemonstratethat，compared to existing schemes，MultiRelay increases throughput by up to 6 times and reduces transaction latency by up to 70% ，providing an inovativecros-chainschemeforcomplexcloud-edgeendarchitectureapplications involvingmulti-chaincollboration， featuring both high performance and scalability.

0引言

物联网设备数量的激增以及5G技术的广泛应用，催生出一系列对时延和资源具有较高要求的新兴应用，这些应用促使资源和服务从传统云中心，经由地理上广泛分布、逻辑上分层组织的边缘/雾节点，向网络边缘转移[1]。（剩余21980字）
