Detailed description of the preferred embodiments
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
The embodiment of the application provides a voucher index storage method for asset class evidence, as shown in fig. 1, comprising the following steps:
And 102, receiving a service request message and first house purchasing information sent by the nodes on the blockchain by the intelligent contract.
In the embodiment of the application, based on the characteristics of the block chain, intelligent contracts are arranged on the nodes corresponding to the block chain, wherein the triggering conditions of the intelligent contracts are to receive service request messages sent by buyers and sellers. The first house purchasing information comprises identity information, house information and the like of the two purchasing parties. Therefore, the human resources can be optimized, the transaction time can be shortened, and the trust degree of the buyer and the seller can be improved.
And 103, the intelligent contract determines house purchasing process information corresponding to the house purchasing information according to the service request message.
And step 104, executing a preset house purchasing process according to the first house purchasing information and the house purchasing process information by the intelligent contract to generate second house purchasing information.
In the embodiment of the application, the buyer and the seller can request operations such as verification, house selection, signing, recording and the like through the service request information. The house purchase procedure information refers to steps required for completing a corresponding service. The house purchasing process generally comprises information authentication and data processing, wherein the data processing refers to processing of the intelligent contract according to a preset program according to a request of a user. For example, house selection requires the buyer to select a house source or propose house purchasing conditions, appoint house-viewing time, and the like. By writing the steps into the intelligent contract, the intelligent contract replaces manpower to carry out house source display, time appointment and other work with the buyer, and the work efficiency is greatly improved. The information authentication means that the intelligent contract can effectively verify the information of both the buyer and the seller, and the trust level of both the buyer and the seller is increased.
In addition, in order to further prevent personal information from being leaked in the house purchasing process, in the embodiment of the application, the intelligent contract receives the identity information sent by the house purchasing nodes in the block chain, then the identity information is converted into the hash value by using the preset hash function, the hash value is used as the identifier of the house purchasing nodes, and the hash value has uniqueness, so that the user identity information is converted into the hash value, the user information safety can be protected, and each house purchasing node can be distinguished. And finally, writing the identifier of the house purchasing node and the second house purchasing information into the same block to prevent the identifier of the house purchasing node from being tampered and facilitate information query.
For data processing, an intelligent contract may perform a query service, specifically:
receiving a house purchasing progress query message sent by a house purchasing node, wherein the house purchasing progress query message comprises: identification of the house purchase node.
And determining a target block according to the identifier of the house purchasing node, wherein the target block is the block with the shortest creation time corresponding to the identifier of the house purchasing node. The timeliness of the query result is ensured by querying the target block, so that the latest house purchasing progress is queried. And according to the identifier of the house purchasing node, acquiring corresponding second house purchasing information from the target block, and returning the corresponding second house purchasing information.
The intelligent contract can also prompt information for the house purchasing progress and other contents according to the request or setting of the user, for example, in order to avoid missing the time requirement of a certain house purchasing link, the buyer hopes that the system can prompt the information for the corresponding time, and the intelligent contract can execute the prompted service. The specific implementation method comprises the following steps: the intelligent contract generates prompt information according to the result obtained by the current step of the house purchasing process and/or the next step to be executed; and the intelligent contract writes the prompt information into the block and sends the prompt information to the corresponding house purchasing node. Therefore, the prompt information of each link of house purchasing can be traced. As an embodiment, for example, the current house purchasing step is house selection, the next house purchasing step is subscription, the intelligent contract may issue a time prompt for subscription or a material prompt required to be prepared according to an execution result of the house selection step, and the intelligent contract may also issue a time prompt for subscription or a material prompt required to be prepared according to the subscription step to be performed.
In addition, the intelligent contract can also realize electronic signing, and particularly, the intelligent contract initiates verification on first house purchasing information in a block chain;
after the verification is passed, the intelligent contract generates an electronic agreement according to the identity information of the buyer and the seller of the house, the house purchasing price and the agreement information reached by the buyer and the seller;
the intelligent contract writes the electronic protocol into the block and sends the electronic protocol to the corresponding house purchasing node. The identity information of the house buyer and the house seller, the house buying price and the agreement information of the house buyer and the house seller come from the first house buying information.
And 105, writing the first house purchasing information and the corresponding second house purchasing information into the block by the intelligent contract.
In the embodiment of the application, the first house purchasing information comprises identity information, house information and the like of the two buying parties, and the second house purchasing information is information generated by executing a house purchasing process by the intelligent contract, and comprises trading data, point data, commission income and the like. The data are stored in the block chain through the intelligent contract so as to ensure that verification can be carried out according to the data on the chain when disputes occur between the buyer and the seller.
