Research And Implementation Of Blockchain Consistency Performance Based On Hyperledger Fabrci Framework

Hyperledger Fabric is the representative of the blockchain technology framework generated in the era of blockchain 3.0.Hyperledger Fabric is characterized by modularity and pluggability.Therefore,it can flexibly choose the construction and application of blockchain applicationsaccording to specific application scenarios and needs.Development method.The process of Hyperledger Fabric achieving blockchain consistency is not only the execution process of the consensus algorithm,but the execution-sort-verification mode to achieve the consistency of the system data.This article analyzes the consistency process of the Hyperledger Fabric blockchain,And apply the conclusion to the design and implementation of specific blockchain applications.The main contents are as follows:1.This article divides the functional modules of Hyperledger Fabric,and designs a comparative test for the pluggable options of each module.It uses Hyperledger Caliper as a test tool,uses Docker to build a test network,and uses JavaScripts to write test loads,plotting,and analysis tests.result.2.This article selects two types of blockchain application scenarios from the new coronary pneumonia incident and exposed social problems in 2020.These are the charity rescue platform that uses blockchain to solve the crisis of philanthropic credibility and the use of blockchain to solve medical data cross.The medical data sharing platform shared by the platform hascompleted the requirements analysis,system design and Hyperledger Fabric blockchain network design of the application platform.3.According to the design plan of the application platform,use Docker containers to build a simulated Hyperledger Fabric blockchain network for the application platform,use Go language to write smart contracts for the application platform,and use Hyperledger Fabric's Node.js SDK to complete the application platform client implementation.
