基于区块链的长租房可靠交易系统设计与实现

Design and implementation of reliable transaction system for long-term rental housing based on blockchain

针对当前长租房系统中出现的难以维权、信息不对称等问题,同时改善用户的使用体验,开发一套基于区块链的长租房可靠租赁交易系统。从用户的实际需求与利益出发,系统基于区块链技术的不可篡改性、自治性等特点,依托于共识机制,并通过智能合约进行交易,同时根据现实需求对当前区块链网络结构与共识算法进行优化。能够解决租房过程中“第三方信任”的问题,可以提高平台的用户可信度、改善国内长租房整体环境,响应国家政策、保障民生,推动国内长租房市场健康蓬勃发展。

In view of problems such as difficulty in safeguarding rights and information asymmetry in the current long-term rental system,meanwhile for improving the user experience,the paper develops a set of long-term rental housing transaction system based on blockchain.The system is based on the actual needs,interests of users and the characteristics of blockchain technology,such as immutability and autonomy.Relying on the consensus mechanism,transactions are conducted through smart contracts.Furtherly,the current blockchain network structure and consensus algorithm are optimized according to the actual needs.It can solve the“third party trust”problem in the rental process,improve the credibility of users of the system and the environment of domestic rental houses,respond to national policies,protect people′s livelihood,and promote the healthy and vigorous development of China′s rental market.
