基于区块链技术的房产交易系统的设计与实现DesignandImplementationofRealEstateTransactionSystemBasedonBlockchainTechnology摘要随着人们的生活逐渐富足，社会压力的不断增加，购房租房的需求也逐年增长。然而传统的房产交易系统存在着黑中介、假房源、成本高、政策推广缓慢等诸多问题，Web2.0搭建的房产交易系统显然不能很好的解决这些问题。随着Web3.0时代到来，区块链技术的引用已经逐渐成为时代项目开发的热潮，有了区块链技术作为系统底层，使系统更加智能。本文针对现有的房产交易平台现状，采用区块链技术开发，提出了以区块链技术为底层开发的房产交易系统。本文在原有的房产交易系统的基础上引入区块链技术作为底层，使系统中的信息不可篡改，可解决合约纠纷、黑中介、房产信息造假等诸多问题。同时系统的房源信息基于区块链技术也做到了数据信息公开共享。系统的开发服务端使用的是Go语言搭建，底层逻辑使用HyperledgerFabric来进行逻辑操作，网络节点中的交易或者更改数据的验证等操作需要区块链网络中所有节点来进行共同验证，可以有效的杜绝黑中介假信息等。使用Vue+Element技术来搭建前端界面使用Docker容器开发来使系统更容易部署与运维。运用区块链技术搭建房产交易系统，解决了传统房产交易系统的痛点。同时论文根据具体的实现，给出了系统的测试方案，并且对系统进行功能、性能、安全测试，最后对系统进行测试结果进行分析，证实系统能达到预期效果。关键词：区块链；HyperledgerFabric智能合约；房产交易系统AbstractWiththegradualaffluenceofpeople'slivesandtheincreasingsocialpressure,thedemandforhousepurchaseandrentalisalsoincreasingyearbyyear.However,therearemanyproblemsinthetraditionalrealestatetradingsystem,suchasblackintermediary,fakehouses,highcost,slowpolicypromotionandsoonTherealestatetradingsystembuiltby0obviouslycannotsolvetheseproblemswell.WithWeb3Withtheadventoftheeraofblockchain,thereferenceofblockchaintechnologyhasgraduallybecometheupsurgeofprojectdevelopmentintheera.Withblockchaintechnologyasthebottomlayerofthesystem,thesystemismoreintelligent.Inviewofthecurrentsituationoftheexistingrealestatetradingplatform,thisthesisadoptsblockchaintechnologytodevelop,andputsforwardarealestatetradingsystembasedonblockchaintechnology.Basedontheoriginalrealestatetradingsystem,thisthesisintroducesblockchaintechnologyasthebottomlayer,sothattheinformationinthesystemcannotbetamperedwith,andmanyproblemssuchascontractdisputes,blackintermediary,realestateinformationfraudandsooncanbesolved.Atthesametime,thehousinginformationofthesystemisbasedonblockchaintechnology,andthedatainformationispubliclyshared.Thedevelopmentserverofthesystemisbuiltingolanguage,andtheunderlyinglogicuseshyperledgerfabricforlogicoperation.Theverificationoftransactionsorchangeddatainnetworknodesrequiresthejointverificationofallnodesintheblockchainnetwork,whichcaneffectivelyeliminateblackintermediaryandfalseinformation.Vue+Elementtechnologyisusedtobuildthefront-endinterface,anddockercontainerdevelopmentisusedtomakethesystemeasiertodeployandoperate.Usingblockchaintechnologytobuildarealestatetradingsystemsolvesthepainpointsofthetraditionalrealestatetradingsystem.Atthesametime,accordingtothespecificimplementation,thethesisgivesthetestschemeofthesystem,andteststhefunction,performanceandsecurityofthesystem.Finally,thetestresultsofthesystemareanalyzedtoconfirmthatthesystemcanachievetheexpectedeffect.Keywords:Blockchain;HyperledgerFabric;RealEstateTradingSystem目录TOC\o"1-3"\h\z\u第1章绪论......................................................................................................31.1研究背景........
