the requirements are four: whether the house sale rental platform can be trusted by the user;
the fifth requirement: whether the house renter has subsequent trust requirements after selling or renting.
A house sale rental platform based on a block chain is mainly aimed at a person who has purchase requirements and rental requirements on houses, and a user using the platform enters the platform through network equipment and operates according to distributed authorities. Based on the characteristics of non-tampering, traceability and disclosure of the block chain technology, the trueness and the credibility of the platform are realized, and the platform can enable a user to pay a small amount of cost to obtain reliable and credible house resources.
As shown in fig. 2, a block chain based real estate information sharing platform adopts a block chain technology, transfer service is performed through the block chain, transfer information is stored on the block chain, transactions between two parties are realized through intelligent contracts, and the intelligent contracts guarantee the security of the transactions; the authentication information of the user is identity card information, name and the like, the identity information is uploaded to the block chain, the property information is the authentication information of the house source, and the part of the information is also stored in the block chain. Part of the information is stored in the database, and part of the information, such as the identity information of the user and the information of the house source, is stored on the blockchain; and after generating a hash value by using the information of the user and the house source information, the hash value is used as a remark, and the user is stored in the block chain after finishing verification.
As shown in fig. 3, the intelligent contract implements the process of real estate transaction, and the steps are as follows:
the method comprises the following steps: a user submits a request for house purchase or house renting;
step two: the block chain generates a contract according to the information submitted by the user, and then the user signs;
step three: judging whether 72 hours are reached by the block chain, determining that the house source is credible, and automatically signing and executing a contract if the house source is credible;
step four: if the time does not reach 72 hours, judging whether the user withdraws, if yes, canceling the contract, and if not, returning to the third step.
As shown in fig. 4, the house property information sharing platform is structured, and the top layer is an interface display of the user, and provides functions of registering, logging in, entering information and the like. The functional module comprises message management, house source information management, transaction management, personal information management, an incentive method and system management; information in the house source information management and the personal information management needs to be stored in the block chain, and then a hash value is generated according to the information and stored in the block chain.
