Abstract
With the increase of the housing population, it is very important for renters to find credible housing information through rental platforms. However, due to the imperfection of relevant laws and insufficient supervision of the housing rental market, problems have emerged one after another. In this article, we propose a housing rental scheme based on redactable blockchain, introducing a trusted third party to verify the homeowner rental listings, and fundamentally preventing false listings from flowing into the housing rental market. Specifically, a trusted third party similar to the housing authority will issue a verifiable claim for the homeowners listing, and then the accounting node of the consortium blockchain will publish the verified listing information on the blockchain so as tenants to make inquiries according to their needs. At the same time, we use the new chameleon hash to build a redactable blockchain. After the homeowner proposes to change the housing price or housing information, the content of the historical block is modified as required. Thus, to a certain extent, the changes in housing prices can be monitored to curb chaos in the housing rental market.
Highlights
With the development of social economy and changes of people’s concepts, the housing rental market’s demand has increased significantly and the number of renters has increased year by year
There are selfish mining attacks in blockchain where attackers compromise the blockchain system by exploiting the vulnerability of the consensus mechanism [2]; while semiselfish mining attacks are proved by Li et al through simulation that semiselfish mining is impossible in practice [3]
We introduce a new chameleon hash to achieve the editable character of the consortium blockchain as a way to build a housing rental platform
Summary
With the development of social economy and changes of people’s concepts, the housing rental market’s demand has increased significantly and the number of renters has increased year by year. The abovementioned problems have severely affected the vigorous development of the housing rental market and increased the additional burden of renters. Solving the various problems in the housing rental market plays a very important role in meeting the housing needs of residents and promoting stable economic and social development. Blockchain transactions are generated by participating entities. The transactions are packaged into blocks and added to the blockchain by miners in chronological order [1]. Participating entities in the blockchain need to update the block regularly and store it. The use of blockchain in these scenarios cannot be directly applied to the housing rental market
