The specification may use the phrases "in one embodiment," "in another embodiment," "in yet another embodiment," or "in other embodiments," which may each refer to one or more of the same or different embodiments in accordance with the application.
The embodiment of the application provides a block chain-based real estate transaction method which can be applied to intelligent contracts of block chains. In the application, a bank, a house administration office and the like can jointly construct an alliance chain in advance, each organization corresponds to one network node in the alliance, and transaction parties (buyers/sellers) needing house property transaction can also be added into the alliance chain in an authorization mode, namely, each buyer and each seller respectively correspond to one network node in the alliance chain. The federation chain/blockchain is deployed with an intelligent contract, and the method in this embodiment is specifically applied to the intelligent contract.
As shown in fig. 1, the method in this embodiment includes the following steps:
step S101, receiving a transaction request aiming at a target property sent by a first network node, wherein the transaction request at least comprises identification information of the target property; the transaction request is generated by the first network node based on the corresponding identification information of the target property after the target property is determined;
in the specific implementation process of this step, the first network node is a network node corresponding to the first electronic device of the buyer, that is, the first network node/the first electronic device generates a corresponding transaction request according to the identification information of the target property after determining the target property desired to be purchased, and then sends the transaction request to the intelligent contract. The identification information of the target property is generated in advance by an intelligent contract according to the property information and is stored in a block chain, and the identification information can be specifically a character string, a two-dimensional code and the like and is used for uniquely representing the target property.
Step S102, obtaining the selling state of the target property by using a prophetic machine module based on the identification information in the transaction request;
in this embodiment, the intelligent contract includes an agent contract and an application contract, and the application contract is provided with a real estate information synchronization module. The prediction machine module is constructed by a plurality of nodes which have the authority to access the data interface of the housing administration; the node may be formed by an organization such as a public inspection method, a head office, etc., to ensure that the node in the predictive engine module/network is relatively trusted.
Therefore, after the intelligent contract receives the transaction request sent by the first network node, the real estate authentication event can be triggered by calling the interface provided by the proxy contract through the real estate information synchronization module deployed in the application contract. The prediction machine module under the chain monitors the verification event, then acquires a target interface address from the block chain, and accesses the house management bureau to acquire the selling state of whether the house property is sold according to the target interface address. Specifically, each node of the predictive language machine module can acquire the selling state of the target property according to the target interface address, gather the selling state results acquired by each node to acquire the final selling state result of the target property, then return the acquired final selling state result to the broadcasting node of the predictive language machine module, write the final selling state result into the agent contract of the intelligent contract through the broadcasting node, and then invoke the application contract.
In specific implementation, the detailed process of obtaining the selling state of the target property is that the intelligent contract sends a selling state obtaining request to the predicting machine module based on the agent contract according to the transaction request; the selling state obtaining request comprises identification information of a target property; receiving the selling state of the target property obtained by the predicting machine module accessing the property management bureau based on the identification information of the target property and the target interface address based on the agent contract; the target interface address is obtained by the predictive engine module from a blockchain. Specifically, a property information synchronization module in the intelligent contract calls an agent contract, and the agent contract sends a selling state acquisition request to a prediction machine module according to the identification information of the target property in the transaction request; and the predictive teller module outside the block chain/alliance chain acquires a target interface address from the block chain, then accesses the house management bureau according to the target interface address, and acquires the selling state of the corresponding target house property from the house management bureau according to the identification information in the selling state acquisition request. Therefore, the current selling condition of the target property can be accurately known, whether the target property is sold currently or not is accurately determined, and a foundation is laid for the subsequent property transaction according to the selling state.
And step S103, responding to the house property transaction request based on the selling state of the target house property to complete the house property transaction or terminate the house property transaction.
The selling state in this step specifically includes a sold state and an unsold state, and the responding to the house property transaction request based on the selling state of the target house property to complete the house property transaction or terminate the house property transaction specifically includes: under the condition that the selling state is the unsold state, the house property transaction is completed; in the case where the selling state is the sold state, the property transaction is terminated.
In this embodiment, after the transaction request of receiving first network node is closed to intelligence, can be through calling the prelude machine module, utilize the prelude machine module to obtain the selling state of the target property that mesh and identification information correspond, can make the selling state of the target property that obtains more accurate from this, for follow-up accurate carrying out the property transaction based on the property selling state provides the guarantee, only can carry out the property transaction for selling under the condition that the state is not sold promptly, the problem of "two sells in one room" has been solved, the efficiency of the property transaction has been improved.
On the basis of the foregoing embodiment, another embodiment of the present application provides a block chain-based real estate transaction method, specifically as shown in fig. 2, including the following steps:
step S201, receiving the house property information to be sold released by each second network node;
in this step, the second network node is a network node corresponding to the second electronic device of the seller. That is, the second electronic device/the second network node may send the property information to the intelligent contract when the property needs to be sold and produced. Specifically, the house property information after structure notarization is identified by a judicial law is sent to a house property digitalization module in an intelligent contract.
Step S202, processing each house property information to be sold to obtain corresponding identification information;
in the specific implementation process of the step, the real estate information is specifically processed by a real estate digitizing module in the intelligent contract, and identification information such as character strings or two-dimensional codes and the like for uniquely representing the real estate is obtained. The identification information may include critical information such as the location of the property, price quoted, age of residence, age of use, time of construction, size of the house, etc.
Step S203, storing each property information identification information to a block chain;
in this step, after the house property digitization module processes and obtains the identification information of the house property, the identification information can be further stored, that is, the identification information is stored in the block chain, and a foundation is laid for each subsequent first network node to acquire the identification information from the block chain and perform house property transaction according to the identification information.
Step S204, at least storing each property information to a preset storage position outside the block chain;
in this step, the blockchain can only store data of a character string type, so that intuitive and detailed property information of types such as pictures, videos and the like can be stored in a storage device/database outside the blockchain, and information such as property position, quotation, living age, service life, construction time, house size and the like can also be stored in a storage device/database outside the blockchain, so that a basis is provided for a subsequent first network node to acquire detailed and intuitive property information from the chain according to identification information obtained from the chain, and the first network node can determine a target property conveniently.
In the specific implementation process of the step, the association relationship between the property information to be sold and the corresponding identification information can be established. Then, when each property information is stored to a predetermined storage location outside the blockchain, the association relationship between the property information and the corresponding identification information can be stored to the predetermined storage location outside the blockchain together. And the corresponding property information can be quickly found by searching the association relation according to the identification information.
Step S205, broadcasting each identification information to at least one first network node in the block chain, so that the first network node acquires corresponding property information from the predetermined storage location based on each identification information, so as to determine the target property.
Step S206, receiving a transaction request aiming at a target property sent by a first network node, wherein the transaction request at least comprises identification information of the target property; the transaction request is generated by the first network node based on the corresponding identification information of the target property after the target property is determined;
in this step, the property digitalization module in the intelligent contract may broadcast each identification information stored in the blockchain at regular time, and after receiving each identification information broadcast by the intelligent contract, the first network node may first obtain the property information corresponding to each identification information from a predetermined storage location according to the identification information and the association relationship between the identification information and the property information; and then the first network node determines a target property to be purchased according to the property information, and further generates a transaction request according to the identification information of the target property. In generating the transaction request, the transaction request may be generated according to a purchase operation of the user, and the purchase operation may be specifically clicking a virtual purchase key, inputting a predetermined purchase gesture, and the like.
In this step, before receiving the transaction request for the target property sent by the first network node, the intelligent contract needs to determine whether the first network node is the target first network node with the property of buying/transaction, and after determining that the first network node is the target first network node with the property of transaction, the intelligent contract receives the transaction request for the target property sent by the target first network node. The process of specifically determining whether the first network node is a target first network node with transaction qualification is as follows: the intelligent closing date generates a random number for each first network node; acquiring a target number based on a speaker module; determining at least one random number as a mid-signed number based on at least the random numbers of the first network nodes and the target number, for example, determining a random number smaller than the target number as a mid-signed number; and finally, determining the first network node corresponding to the middle-signed number as the target first network node. In the specific implementation process, the process of acquiring the target number based on the predictive speaker module is as follows: and after the number shaking event is monitored by the prediction machine module, the prediction machine module generates a plurality of preselected numbers under the chain by using a random seed and a verifiable random function provided by a room administration and returns each preselected number to the chain. Because the predictive machine network is provided with a plurality of nodes, only one node can generate an effective target number according to the random seeds provided by the house administration, and other nodes generate preselected numbers according to other random seeds, so that the generation process of the target number is safe, and the target number is not easy to identify. The number generator module may generate a plurality of preselected numbers, and return a preselected number set including the target number to the chain, whereby the intelligent contract may determine the target number from the preselected number set based on a characteristic of the verifiable random function, i.e., only preselected numbers less than the generation threshold of the bureau of housing administration may become the target number of the current round. It is often the case that only a preselected number generated based on a random seed provided by the homeowner's office will be less than a threshold generated by the homeowner's office; however, if all the pre-numbers are larger than the threshold generated by the administration office, the first network node corresponding to the smallest random number can be directly determined as the target network node according to the size sequence of the random numbers by adopting a polling principle.
Step S207, sending a selling state acquisition request to the language prediction machine module based on the agent contract according to the transaction request; the selling state obtaining request comprises identification information of a target property; receiving the selling state of the target property obtained by the predicting machine module accessing the property management bureau based on the identification information of the target property and the target interface address based on the agent contract; the target interface address is obtained by the predictive engine module from a blockchain;
and S208, responding to the property transaction request based on the selling state of the target property to complete the property transaction or terminate the property transaction.
In the specific implementation process of the step, when the selling state of the target property is determined to be the non-selling state, the property information synchronization module in the intelligent contract executes the property transaction, for example, generates a buying-selling contract corresponding to the target property, so as to complete the transaction of the target property. Meanwhile, the intelligent dating call a data interface of a house administration to modify the selling state of the target property, and modify the unsold state into the sold state; and the intelligent contract can also send the sold state information of the target property to each network node in the block chain in a broadcasting mode, so that other first network nodes (other buyers) can synchronously acquire the sold message of the target property. When the selling state of the target property is determined to be the sold state, the property information synchronization module in the intelligent contract can terminate the property transaction and feed back the message of terminating the property transaction to the first network node so as to prompt the first network node to finish the property transaction.
In the specific implementation process of the embodiment, the intelligent contract may further determine an active first network node according to the received transaction request; and after each identification information is broadcasted to at least one first network node in the block chain, sending prompt information to the active first network node. Specifically, a transaction analysis module is deployed in the intelligent contract, so that transaction request information, transaction completion information or transaction failure information can be sent to the transaction analysis module by the intelligent contract when the intelligent contract receives a transaction request or after the transaction is completed, the transaction analysis module is used for analyzing the house property transaction to determine an active buyer, and a guarantee is provided for further sending prompt information to an active first network node to prompt the first network node to perform house property transaction after each identification information is broadcast subsequently.
In this embodiment, after the transaction request of receiving first network node is closed to intelligence, through calling the prelude machine module, utilize the prelude machine module to obtain the selling state of the target property that mesh and identification information correspond, can make the selling state of the target property that obtains more accurate from this, for follow-up accurate the carrying out the property transaction based on the property selling state provides the guarantee, only can carry out the property transaction for selling under the condition that the state is not sold promptly, the problem of "two sells in one room" has been solved, the efficiency of the property transaction has been improved. The target first network node with the property of purchasing the house can be determined fairly according to the target number and the random number of each first node, and the fairness of house property transaction is guaranteed. The system and the method have the advantages that the functions of house property digitalization, transaction synchronization, number shaking and drawing lots and the like are realized through the block chain and the intelligent contract, the conditions of information opaqueness, data inconsistency, third-party cheating and the like in the house property transaction process are avoided, house property transaction generation is reduced, house property transaction efficiency is improved, and house property transaction fairness is maintained.
Another embodiment of the present application provides a house property transaction method based on a block chain, where the transaction method in this embodiment may be specifically applied to a first network node in the block chain, where the first network node is a network node corresponding to a first electronic device of a buyer in the block chain. Specifically, as shown in fig. 3, the method in this embodiment includes the following steps:
step S301, determining a target property based on the obtained property information;
in the specific implementation process of the step, the first network node receives identification information of each to-be-sold property broadcasted by the intelligent contract; then the first network node acquires the property information corresponding to the identification information from a preset storage position outside the block chain based on the identification information; and finally, determining the target property based on the property information. In this step, the property information corresponding to the identification information is acquired from the predetermined storage position according to the identification, so that a foundation is laid for subsequently determining a target property to be purchased according to the property information and then generating a transaction request based on the identification information corresponding to the target property.
Step S302, generating a transaction request based on the identification information of the target property;
in this step, the identification information is generated in advance by the intelligent contract according to the property information issued by the second network node and is stored in the block chain, and the identification information may specifically be a character string, a two-dimensional code, and the like, and is used for uniquely representing the property. The second network node is a network node corresponding to the second electronic device of the seller in the blockchain. By storing the identification information into the block chain, the intelligent contract can be broadcasted according to the stored identification information, and at least one first network node receives the identification information of each to-be-sold property broadcasted by the intelligent contract. When generating the transaction request, the step may specifically generate the transaction request based on a purchase operation of the user, where the purchase operation may specifically be to click a virtual purchase key, input a predetermined purchase gesture, and so on.
Step S303, sending the transaction request to an intelligent contract so as to obtain the selling state of the target property through a language predicting machine module by using the intelligent contract according to the identification information in the transaction request;
the intelligent contract in the embodiment comprises an agent contract and an application contract, and a real estate information synchronization module is deployed in the application contract. The prediction machine module is constructed by a plurality of nodes which have the authority to access the data interface of the housing administration; the node may be formed by an organization such as a public inspection method, a head office, etc., to ensure that the node in the predictive engine module/network is relatively trusted.
Therefore, after the intelligent contract receives the transaction request sent by the first network node, the real estate authentication event can be triggered by calling the interface provided by the proxy contract through the real estate information synchronization module deployed in the application contract. The prediction machine module under the chain monitors the verification event, then acquires a target interface address from the block chain, and accesses the house management bureau to acquire the selling state of whether the house property is sold according to the target interface address. Specifically, each node of the forecast machine module can acquire the selling state of the target property according to the target interface address, the selling state results acquired by the nodes are collected to obtain the final selling state result of the target property, the obtained final result is returned to the broadcast node of the forecast machine module, the broadcast node of the forecast machine module is written into an agent contract of the intelligent contract, and the agent contract further calls the application contract, so that the application and the jade can respond to the property transaction request according to the selling state of the target property to complete the property transaction or terminate the property transaction.
In specific implementation, the detailed process of obtaining the selling state of the target property is that the intelligent contract sends a selling state obtaining request to the predicting machine module based on the agent contract according to the transaction request; the selling state obtaining request comprises identification information of a target property; receiving the selling state of the target property obtained by the predicting machine module accessing the property management bureau based on the identification information of the target property and the target interface address based on the agent contract; the target interface address is obtained by the predictive engine module from a blockchain. Specifically, a property information synchronization module in the intelligent contract calls an agent contract, and the agent contract sends a selling state acquisition request to a prediction machine module according to the identification information of the target property in the transaction request; and the predictive teller module outside the block chain/alliance chain acquires a target interface address from the block chain, then accesses the house management bureau according to the target interface address, and acquires the selling state of the corresponding target house property from the house management bureau according to the identification information in the selling state acquisition request. Therefore, the current selling condition of the target property can be accurately known, whether the target property is sold currently or not is accurately determined, and a foundation is laid for the subsequent property transaction according to the selling state.
And step S304, receiving the intelligent contract according to the selling state of the target property and the response result of the property transaction request so as to complete the property transaction or terminate the property transaction.
In the specific implementation process of the step, when the selling state of the target property is determined to be the non-selling state, the property information synchronization module in the intelligent contract executes the property transaction, for example, generates a buying-selling contract corresponding to the target property, so as to complete the transaction of the target property. Meanwhile, the intelligent dating call a data interface of a house administration to modify the selling state of the target property, and modify the unsold state into the sold state; and the intelligent contract can also send the sold state information of the target property to each network node in the block chain in a broadcasting mode, so that other first network nodes (other buyers) can synchronously acquire the sold message of the target property. When the selling state of the target property is determined to be the sold state, the property information synchronization module in the intelligent contract can terminate the property transaction and feed back the message of terminating the property transaction to the first network node so as to prompt the first network node to finish the property transaction.
The method in the application calls the predictive machine module by utilizing the intelligent contract, obtains the selling state of the target property corresponding to the object and the identification information by utilizing the predictive machine module, can enable the obtained selling state of the target property to be more accurate, provides guarantee for the subsequent property transaction based on the accurate selling state of the property, namely, the property transaction can be carried out only under the condition that the selling state is not sold, solves the problem of 'two selling in one house', and improves the efficiency of the property transaction. The system and the method have the advantages that the functions of house property digitalization, transaction synchronization, number shaking and drawing lots and the like are realized through the block chain and the intelligent contract, the conditions of information opaqueness, data inconsistency, third-party cheating and the like in the house property transaction process are avoided, house property transaction generation is reduced, house property transaction efficiency is improved, and house property transaction fairness is maintained.
The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
