摘    要:针对联盟链扩展能力差、互操作性差、存储资源浪费等问题,借助原有公证人跨链机制研究了一种去中心化的分布式公证人跨链模型。从各个局部链中推选节点组为分布式公证人链——全局链,将全局链作为跨链媒介提升模型的去中心化程度;以JMeter工具对系统的延迟和吞吐量进行测试,并从理论角度对系统存储空间利用率以及安全性进行分析;将所提出的跨链模型用于医疗健康领域,验证了该模型的可行性。

关 键 词:区块链  互操作性  跨链  分布式公证人  全局链

Abstract:Aiming at the problems of poor scalability, poor interoperability, and waste of storage resources in the consortium chain, a decentralized distributed notary cross-chain model is studied with the help of the original notary cross-chain mechanism. A node group is selected from each local chain as a distributed notary chain-global chain, and the global chain is used as a cross-chain medium to improve the degree of decentralization of the model. The JMeter tool is used to test the delay and throughput of the system, and theoretically from the perspective of system storage space utilization and security, the feasibility of the proposed cross-chain model is verified by using it in a medical and health scenario.
Keywords:blockchain  interoperability  cross-chain  distributed notaries  global chain
