After receiving the house information sent by the house and property supplier and the agent cost information sent by the house and property broker, the service platform can generate first transaction data containing the house information and the agent information and issue the first transaction data to the blockchain network; after receiving the agent file information related to the house information sent by the house agency, the service platform can also issue the agent file information to the block chain network.
The house information may include house identification (e.g., house number, etc.) and house value data (e.g., price per unit area of house and total area of house); the agent cost information may include identity information of the property broker (e.g., identity number of the property broker, job number of the property broker, etc.) and agent cost data of the property broker for the premises sold by the local producer. If the house buyer is interested in the house sold by the estate manufacturer, the house buyer can acquire the related information of the house and the related information of the estate agency through the service platform, and the house buyer can acquire the price information of the house provided by the estate manufacturer and the agency fee data collected when the estate agency sells the house. The agent file information may include agent agreement information (e.g., agent contract) and identity information of the property broker, and the agent agreement information may include a scale factor, which is a point of raising provided by the property producer after the property broker sells the premises of the property producer. The service platform issues the agency contract signed by the property agency and the property supplier to the block chain network, so that the property supplier can be prevented from being promoted to the property agency without paying according to the agency contract, or one of the property supplier and the property agency changes to points privately.
After receiving the first transaction information sent by the house buyer and the collection information sent by the real estate agency, the service platform can generate second transaction data containing the first transaction information and the collection information and issue the second transaction data to the blockchain network. The first transaction information may include transaction agreement information (e.g., house purchase contract), which is a transaction certificate for house transaction between the property agency and the house purchaser; the collection information can be generated by the house property intermediary according to a collection certificate sent by the bank, wherein the collection certificate is a transaction certificate of the house initial payment successfully received by the account of the house property manufacturer and paid by the house buyer.
After receiving the second transaction information sent by the house buyer and the repayment information sent by the second house seller, the service platform can generate third transaction data containing the second transaction information and the repayment information, and issue the third transaction data to the blockchain network. The second transaction information may include transfer agreement information (e.g., a house transfer contract), where the transfer agreement information is a transfer certificate for house transfer between the second-hand house seller and the house buyer; the repayment information can be generated by the second-hand house seller according to a repayment voucher sent by the bank, wherein the repayment voucher is a transaction voucher for the second-hand house seller to successfully repay the house credit of the transferred house.
The service platform may also send the second transaction data and the third transaction data to the dispatch office. The house can handle the house-buying user for the house-buying person according to the second transaction data (e.g. house-buying contract, house property certificate, etc.). Alternatively, the house may handle account change for the house buyer based on the third transaction data (for example, house transfer contract, payment information, and the like). The service platform realizes information sharing, the service platform can connect the house buyer with the dispatching station, the house buyer can initiate a house falling application or a household registration change application to the dispatching station through the service platform, and the time cost of the house falling of the house buyer can be saved.

Step S302: and receiving the agent expense information sent by the second block chain link point device.
In one implementation, the proxy cost information may include identity information of the second block-linked point device and proxy cost data of the second block-linked point device identifying the corresponding house for the house. In another implementation, the proxy cost information may further include credit rating information of the second block-linked point device, and the credit rating information may be used to indicate a credit evaluation level of the second block-linked point device, where the higher the credit evaluation level is, the higher the degree to which the second block-linked point device is trusted, and conversely, the lower the credit evaluation level is, the lower the degree to which the second block-linked point device is trusted is.
For example, the second block-linked point device is a block-linked point device used by a property broker, the higher the credit evaluation rating of the property broker, the higher the degree to which the property broker is trusted, the more easily the property broker is selected by the homeowner; the lower the credit rating of the property broker, the lower the degree to which the property broker is trusted and the less likely the house buyer will choose the property broker.
Step S303: first transaction data is generated that includes house information and agent fee information.
Step S304: the first transaction data is published to a blockchain network.
In one implementation manner, the management node device may calculate a first hash value of the first transaction data according to a hash algorithm, and establish an association relationship between the first hash value and the first transaction data; the management node device may generate a first chunk according to the first hash value and the associated first transaction data, and publish the first chunk to the blockchain network. The management node device may use the first hash value as a key, use the first transaction data as a value, establish an association relationship between the first hash value and the first transaction data in a form of a key value pair, and obtain the first transaction data associated with the first hash value through the first hash value. The Hash Algorithm may include, but is not limited to, MD4(Message-Digest Algorithm 4, information Digest Algorithm 4) Algorithm, MD5 Algorithm, SHA (Secure Hash Algorithm) 1 Algorithm, SHA256 Algorithm, SHA512 Algorithm.
In one implementation, the management node device may receive a transaction data acquisition request sent by the third blockchain node device, where the transaction data acquisition request includes a first hash value; the management node device may determine, in response to the transaction data acquisition request, first transaction data associated with the first hash value; the management node device may send the first transaction data to the third blockchain node device.

In one implementation, the management node device may further receive proxy file information corresponding to the house information and sent by the second block link node device, and generate a fourth block according to the proxy file information, and the management node device may issue the fourth block to the block link network. The proxy file information may include proxy protocol information, a first digital signature of the first block link node device, a second digital signature of the second block link node device, and identity information of the second block link node device. The proxy protocol information may include a scaling factor, which is a transfer ratio of resource transfer from the first blockchain node device to the second blockchain node device. The first digital signature is generated by the first blockchain node device encrypting the proxy protocol information by using the public key of the second blockchain node device. And the second digital signature is generated by encrypting the proxy protocol information by using the public key of the second block chain node device after the second block chain node device verifies the first digital signature by using the private key of the second block chain node device. The first block chain node point device encrypts the proxy protocol information by using a public key of the second block chain node point device to generate a first digital signature, only the second block chain node point device can decrypt the first digital signature by using a private key of the second block chain node point device to obtain the proxy protocol information, and other block chain node point devices in the block chain network cannot obtain the proxy protocol information.
For example, in a house buying and selling scenario, a property producer may consign a property broker to sell a house, and the property producer may draw up an agent contract (agent agreement information) that includes a scaling factor that is the number of points the property producer provides to the property broker. The property supplier encrypts the agent contract by using the public key of the property broker to obtain a first digital signature, and sends the first digital signature to the property broker. The real estate agent may decrypt the first digital signature using the private key of the real estate agent to obtain the proxy contract. If the real estate agency has no objection to the proportionality coefficient in the agent contract, the real estate agency encrypts the agent contract by using the public key of the real estate agency to obtain a second digital signature. The property broker generates broker file information including the broker contract, the first digital signature, the second digital signature, and identity information of the property broker. The property broker can send the agent file information to the service platform, and the service platform can generate a fourth block according to the agent file and issue the fourth block to the block chain network. After the house is sold by the house property agency, the house property supplier issues and draws the house property agency according to the proportionality coefficient in the agency contract.
In one implementation, the agent file information corresponding to different houses is different, that is, the scaling factors corresponding to different houses are different. For example, the proportionality coefficient corresponding to a house with good house type and convenient traffic is different from the proportionality coefficient corresponding to a house with poor house type and inconvenient traffic.
In this embodiment of the application, after receiving the house information sent by the first block link point device and the agent cost information sent by the second block link point device, the management node device may generate first transaction data including the house information and the agent cost information, and issue the first transaction data to the block link network; the management node device may also issue proxy protocol information corresponding to the house information and sent by the second block chain node device to the block chain network, where the proxy protocol information includes a transfer ratio of resource transfer from the first block chain node device to the second block chain node device and identity information of the second block chain node device. The first transaction data containing the house information and the agent expense information and the agent file information are issued to the blockchain network by the management node device, each node device in the blockchain network can acquire the house information, the agent expense information and the agent file information, and the house information, the agent expense information and the agent file information issued to the blockchain network cannot be tampered, so that the house information, the agent expense information and the agent file information are public and transparent, and the house information, the agent expense information and the agent file information are shared in the blockchain network. The block chain for storing data in the block chain network ensures that the data stored in the block chain cannot be falsified and forged in a cryptographic mode, and further improves the reliability of the house information, the agency expense information and the agency file information.
