Technical Field

Background

In a transaction business for an item, a user may initiate a transaction request for an item to another user, while in a transaction business for an item, a transaction virtual asset for an item is typically determined by manual calculation (e.g., in a retrofit business for an item, a determination of a retrofit virtual asset for an item is typically made by a user retrofitting an item), and a manual determination manner requires a lot of manpower and time to query for relevant data, thereby affecting the execution efficiency of the transaction business for an item.

Further, if both parties confirm that the transaction is performed on the article, both parties in the transaction service need to perform resource data exchange (for example, for a retrofit service for an article, an initiator of the retrofit service needs to provide the receiver with retrofit virtual asset data for retrofitting the article, and the receiver needs to provide the initiator with the retrofitted article).

However, in the transaction service of the article, it is highly likely that one party in the transaction of the article cannot provide corresponding resource data in the time agreed by the two parties, so that the resource data in the transaction service of the article cannot be exchanged and completed on time, and in this case, the transaction service is likely to fail, thereby reducing the execution success rate of the transaction service.

Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Referring to fig. 1, fig. 1 is a schematic diagram of a network architecture according to an embodiment of the present application. The block chain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like, and is mainly used for sorting data according to time sequence, encrypting the data into an account book, preventing the account book from being tampered and forged, and simultaneously verifying, storing and updating the data. A blockchain is essentially a de-centralized database in which each node stores an identical blockchain, and the blockchain network distinguishes the nodes into core nodes, data nodes, and light nodes, wherein the core nodes are responsible for the consensus of the blockchain network, i.e., the core nodes are consensus nodes in the blockchain network. The process of writing the transaction data into the account book in the blockchain network can be that the client sends the transaction data to the data nodes or the light nodes, then the transaction data is transmitted between the data nodes or the light nodes in the blockchain network in a baton mode until the transaction data is received by the consensus node, the consensus node packages the transaction data into blocks, performs consensus among other consensus nodes, and writes the blocks carrying the transaction data into the account book after the consensus is passed.

It will be appreciated that a blockchain system may include a smart contract that is understood in the blockchain system to be a type of code that each node of the blockchain (including the consensus node) may understand and execute, and that may execute any logic and obtain a result. The user can call the intelligent contract which is already deployed on the blockchain by means of the client initiating a transaction service request, then the data node or the light node on the blockchain can send the transaction service request to the consensus nodes, and each consensus node on the blockchain can respectively run the intelligent contract. It should be appreciated that one or more intelligent contracts may be included in the blockchain, where the intelligent contracts may be distinguished by an identification number (Identity document, ID) or a name, and the transaction service request initiated by the client may also carry the identification number or the name of the intelligent contract, so as to specify the intelligent contract that the blockchain needs to run, after the intelligent contract is run to obtain the execution result, each consensus node may mutually verify whether the execution result is consistent (i.e. perform consensus), and if so, may store the execution result in the respective local ledger and return the execution result to the client.

As shown in fig. 1, the network architecture may include a core node (consensus node) cluster 1000, a data node or light node cluster 100, and a user terminal (client) cluster 10. As shown in fig. 1, the core node cluster 1000 may include a core node 1000a, core nodes 1000b, …, and a core node 1000n, the data node cluster 100 may include a data node 100a, a data node 100b, …, and a data node 100n, and the user terminal cluster 10 may include a user terminal 10a, user terminals 10b, …, and a user terminal 10n.

As shown in fig. 1, the user terminals 10a, 10b, …, 10n may respectively make network connections with the data nodes 100a, 100b, …, 100n, so that the user terminals may perform data interaction with the data nodes through the network connections; the data node 100a, the data nodes 100b, … and the data node 100n can respectively perform network connection with the core node 1000a, the core nodes 1000b, … and the core node 1000n, so that the data node can perform data interaction with the core node through the network connection; the data nodes 100a, 100b, … and 100n are connected to each other so that data interaction can be performed between the data nodes, and the core nodes 1000a, 1000b, … and 1000n are connected to each other so that data interaction can be performed between the core nodes.

Taking the user terminal 10a, the data node 100a and the core node 1000a as an example, the data node 100a may receive a transaction service request (the transaction service request carries an ID or a name of an intelligent contract) sent by the user terminal 10a, and then the data node 100a may send the transaction service request to the core node 1000a through the data node cluster 100; the core node 1000a may run the smart contract, execute the transaction service through the smart contract, obtain an execution result, store the execution result in a memory pool (e.g., a transaction pool), and generate a new block according to the execution result; the core node 1000a may then send the newly generated blocks to other core nodes in the blockchain network according to the node identifiers of the other core nodes (i.e. consensus nodes) in the blockchain network, and the other core nodes check (i.e. perform consensus) the newly generated blocks, and after checking, add the newly generated blocks to the blockchain in which they are stored (i.e. store the execution result into the blockchain after the consensus passes). Each core node in the blockchain network has a node identifier corresponding to the core node, and each core node in the blockchain network can store node identifiers of other core nodes in the blockchain network, so that the generated blocks can be broadcast to other core nodes in the blockchain network according to the node identifiers of other core nodes later, and data stored on all core nodes in the blockchain network are consistent.

The application can propose a data processing method based on the characteristic that the blockchain can not be tampered or forged, thereby enabling the part information of the article to have true reliability, enabling the refitted asset reference value obtained based on the true and reliable part information to be more accurate and reliable, enabling related equipment (such as refitted party equipment refitted the article) to rapidly and accurately determine the final target refitted virtual asset based on the accurate and reliable refitted asset reference value, and improving the execution efficiency of the refitted service of the article; if the item is obtained by the refitting initiator through transaction (e.g., sales transaction) at the refitting party, the refitting initiator needs to transfer the target transaction virtual asset of the item to the refitting party when the appointed time is reached, the refitting party device can initiate a target asset authority transfer request to a third party based on the target refitting virtual asset and the target transaction virtual asset of the item, and the third party can quickly transfer virtual asset data corresponding to the application virtual asset value (the virtual asset value expected to be obtained from the third party device by the refitting party device before the appointed time is reached) to the first device. The specific method provided by the present application will be described below by taking the core node 1000a, the data node 100a, the user terminal 10b, and the user terminal 10c as examples, where the user terminal 10a may be a first device (for example, a device corresponding to a retrofit initiator), the user terminal 10b may be a second device (for example, a device corresponding to a retrofit initiator), and the user terminal 10c may be a third device (for example, a device corresponding to a third party, such as a device corresponding to a virtual asset provider). It should be appreciated that after the user terminal 10a obtains the item from the user terminal 10b through the transaction (the user terminal 10a needs to transfer the target transaction virtual asset to the user terminal 10b when reaching the second constraint), the user terminal 10a may send a modification request for requesting modification of the item to the core node 1000a through the data node 100a, where the modification request may further include part information of the item; subsequently, the core node 1000a may calculate a retrofit asset reference value for determining the item based on the part information and send the retrofit asset reference value to the user terminal 10b; the user terminal 10b may determine a final target retrofit virtual asset based on the retrofit asset reference value; subsequently, the user terminal 10b may send the retrofit electronic contract including the target retrofit virtual asset to the core node 1000a, and the core node 1000a may send the retrofit electronic contract to the user terminal 10a; if the user terminal 10a is not disagreeable to the retrofit electronic contract, an asset confirmation message may be returned to the core node 1000a, and the core node 1000a may send the asset confirmation message to the user terminal 10b. Further, the user terminal 10b may generate a target asset rights transfer request based on the asset confirmation message, the target retrofit virtual asset, and the target transaction virtual asset, and send the target asset rights transfer request to the user terminal 10c through the core node 1000 a; the target asset authority transfer request may include applying for a virtual asset value, a transaction electronic contract for the item (a transaction contract agreed by the user terminal 10a and the user terminal 10 b), where the transaction electronic contract includes user information of a retrofitting initiator and a retrofitting party, an agreed target transaction virtual asset for the item (i.e., a value for the item determined by the retrofitting initiator and the retrofitting party together), a retrofitting electronic contract for the item, basic attribute information of the item (for example, manufacturer information, model information, historical usage record information, historical accident record information, etc.), and the like; the core node 1000a may generate a block for the transaction electronic contract and a block for the retrofit electronic contract, and after the block passes the consensus, the block may be uplink to the affiliated blockchain, thereby ensuring that the transaction electronic contract and the retrofit electronic contract cannot be tampered with, and ensuring the true validity of the data in the transaction electronic contract and the retrofit electronic contract.

Further, the user terminal 10c may confirm, through a blockchain, that the transaction electronic contract and the retrofit electronic contract are authentic, and the provider of the virtual asset data may determine whether to provide the retrofit party with the virtual asset data corresponding to the application virtual asset value in the target asset right transfer request; if the provider of the virtual asset data determines to provide the refitted party with the virtual asset data corresponding to the applied virtual asset value, the core node 1000a and the user terminal 10b may jointly agree on a target time period for transferring the virtual asset data, and transfer the virtual asset data corresponding to the applied asset value to the user terminal 10b in the target time period.

It should be appreciated that for the asset rights transfer business of an item, the blockchain-based approach may enable the data to remain tamper-proof, non-tamperable, and transparent, with the authenticity and reliability being guaranteed, thereby enabling the user to quickly obtain the required virtual asset data from a third party based on the reliable data. The acquisition time of the virtual asset data can be quickened, so that the requirement of the user on the virtual asset data can be responded in time.

It will be appreciated that the method provided by the embodiments of the present invention may be performed by a computer device, including but not limited to a terminal or a server. The node in the embodiment of the invention can be a computer device.

For ease of understanding, please refer to fig. 2-3 together, fig. 2-3 are schematic views of a scene provided by an embodiment of the present application. The ue a shown in fig. 2-3 may be any ue in the ue cluster 10 in the embodiment corresponding to fig. 1, for example, the ue is the ue 10a; the ue B shown in fig. 2-3 may be any ue in the ue cluster 10 in the embodiment corresponding to fig. 1, for example, the ue is the ue 10B; the ue C shown in fig. 2-3 may be any ue in the ue cluster 10 in the embodiment corresponding to fig. 1, for example, the ue is the ue 10C; the blockchain node shown in fig. 2-3 may be any core node in the core node cluster 1000 in the embodiment corresponding to fig. 1, for example, the core node may be the core node 1000b.

It should be understood that the user terminal a may be a user terminal corresponding to the user a, the user terminal B may be a user terminal corresponding to the user B, and the user terminal C may be a user terminal corresponding to the user C; wherein, user b sells the article to user a, user a asks user b to modify the article and then delivers the article to user a, user a and user b sign two types of contracts, one type of contract is a transaction electronic contract of the article, the transaction electronic contract is contracted with the user a to transfer a target transaction virtual asset (for example, 50 ten thousand yuan) to user b when reaching the first contracted time (for example, 2021, 5 months 1); another category is a retrofit electronic contract in which the user a has a contract to transfer the target retrofit virtual asset (e.g., 20 ten thousand yuan) to user b when the second contract time is reached (e.g., 2021, 5, month 1). Wherein the target retrofit virtual asset in the retrofit electronic contract can be determined based on the retrofit asset reference value of the item, and the retrofit asset reference value can be generated by a block link point, as shown in fig. 2, user a can send a retrofit request to the block link point through user terminal a, and the block chain node can invoke the intelligent contract and generate a retrofit asset reference value through the intelligent contract and part information of the item in the retrofit request, the block chain node can send the retrofit asset reference value to user terminal B, and user terminal B can determine the final target retrofit virtual asset based on the retrofit asset reference value; subsequently, user B may determine a target retrofit virtual asset for the item based on the retrofit asset reference value and generate a retrofit electronic contract including the target retrofit virtual asset (the retrofit electronic contract including the target retrofit virtual asset, the user a having a contracted time to transfer the target retrofit virtual asset), user B may send the retrofit electronic contract to user terminal a via user terminal B, if user a is not contextually in the retrofit electronic contract, user a may send a contract confirmation message to the blockchain node via user terminal a, and the blockchain node may send the contract confirmation message to user terminal B.

Further, as shown in fig. 3, the user b may initiate a target asset rights transfer request to the user c (e.g., a provider of virtual asset data) based on the contract validation message, the target transaction virtual asset, and the target retrofit virtual asset, to obtain virtual asset data corresponding to the application virtual asset value (e.g., 65 ten thousand yuan) from the user c. As shown in fig. 3, the user B may send a target asset right transfer request for the item to a block link point through a user terminal B, where the target asset right transfer request may include an application virtual asset value (for example, 65 ten thousand yuan), a transaction electronic contract (a transaction electronic contract in which the user a and the user B are signed) and a retrofit electronic contract (a retrofit electronic contract in which the user a and the user B are signed), and the block link node may send the transaction electronic contract and the retrofit electronic contract to a user terminal a corresponding to the user a, and the user a may return confirmation transaction information to the block link point through the user terminal a.

Further, the blockchain node may send the confirmation transaction information to the user terminal C, the user C may view the confirmation transaction information through the user terminal C, if the user C confirms that the virtual asset data corresponding to the applied virtual asset value is provided to the user b (for example, 65 ten thousand yuan), the user C agrees with the user b through the blockchain node to transfer the target time period of the virtual asset data (for example, 2021, 4, 1, 4, 10, 4, and transfer the virtual asset data corresponding to the applied virtual asset value to the user b in the target time period.

It should be appreciated that, if the user B receives the virtual asset data corresponding to the applied virtual asset value transferred by the user c, the user B may send an asset receipt acknowledgement message to the blockchain node, and the blockchain node may transfer the asset acquisition rights of the target transaction virtual asset and the target retrofit virtual asset to the user c based on the asset receipt acknowledgement message, that is, when the asset transfer contract time (e.g., 2021, 5, 1), the user a does not need to transfer the target transaction virtual asset and the target retrofit virtual asset to the user B, but to the user c.

Further, referring to fig. 4, fig. 4 is a flowchart of a data processing method according to an embodiment of the present application, where the method may be performed by a blockchain node (e.g., a core node in the embodiment corresponding to fig. 1) or may be performed by a blockchain node together with a user terminal (e.g., a user terminal in the embodiment corresponding to fig. 1). The following will describe the method performed by the block link point as an example, wherein the data processing method may at least include the following steps S101-S106:

step S101, obtaining a refitting request for an article sent by first equipment; the article is obtained by the first equipment through transaction from the second equipment; the retrofit request includes part information of the article.

In the present application, the article may refer to an article that may be used to conduct a transaction, for example, the article may be a component of an aircraft (e.g., an engine, a landing gear, a fuselage, a component that constitutes an engine, a component that constitutes a landing gear, a component that constitutes a fuselage, etc.), an associated article of an aircraft or engine (e.g., a maintenance tool, etc. for an aircraft or engine), etc., and are not illustrated herein. It should be appreciated that for an item, a first user (corresponding to a first device) in possession of the item may transact with a second user (corresponding to a second device), which may include a buy and sell transaction, a retrofit transaction, a lease transaction, etc., for which the second user may agree on an asset transfer agreement time with the first user as well as on a virtual asset (e.g., 100 ten thousand yuan). The second user and the first user can sign a trade electronic contract with the appointed virtual asset based on the asset transfer appointed time, the trade electronic contract comprises order information (such as model number, quantity and the like) of the trade article, and the appointed virtual asset can be also included, wherein the appointed virtual asset is the contract virtual asset in the trade electronic contract, and after the trade electronic contract is validated, one user needs to transfer the contract virtual asset to the other user at the asset transfer appointed time.

For example, if the transaction is a sales transaction, the first user obtains the item from the second user through the sales transaction, the second user and the first user need to sign a transaction electronic contract (i.e. a sales contract) for the item, the transaction electronic contract needs to include a target transaction virtual asset (i.e. a sales value) commonly agreed by the first user and the second user, and an asset transfer appointment time, and the first user needs to transfer the target transaction virtual asset to the second user when the asset transfer appointment time is reached. Wherein the target transacted virtual asset may be determined by a virtual asset assessment reference, and the virtual asset assessment reference may be generated by the blockchain node upon receipt of a transaction request (sales request) sent by the first user. The process of the transaction (trade transaction) business for the article can be specifically that a transaction request for the article sent by the first equipment can be obtained; the transaction request is for requesting the retrieval of the item from the second device; wherein the transaction request may include a historical repair record of the item and an associated quantity of the item; wherein the association number may refer to the number of associated items having the same function as the item; according to the transaction request, calling an intelligent contract, and determining a virtual asset evaluation reference value of the article through the intelligent contract, the historical maintenance record and the associated quantity; the virtual asset evaluation reference value is used for evaluating and referencing the transaction virtual asset of the article; subsequently, the transaction request and the virtual asset evaluation reference value may be sent to the second device, such that the second device determines a target transaction virtual asset that matches the virtual asset evaluation reference value, generates a transaction electronic contract with the target transaction virtual asset according to the second contract time (i.e., the asset transfer contract time), and returns the transaction electronic contract; and sending the transaction electronic contract to the first device, if the first device has no objection to the transaction electronic contract, returning a second contract confirmation message to the blockchain node, receiving the second contract confirmation message returned by the first device based on the transaction electronic contract, and sending the device account corresponding to the second device to the first device according to the second contract confirmation message, so that when the first device reaches the second appointment time, transferring the virtual asset data corresponding to the target transaction virtual asset to the device account corresponding to the second device.

The specific method for determining the virtual asset evaluation reference value of the article through the intelligent contract, the historical maintenance record and the associated quantity can be that the historical maintenance record can be input into a value prediction model through the intelligent contract, and the maintenance characteristics of the historical maintenance record can be extracted through the value prediction model; determining a first virtual asset reference value for the item by the predictive model and the repair feature; matching the association quantity with a quantity threshold value, and determining a second virtual asset reference value of the article according to a matching result; and determining a virtual asset evaluation reference value of the item according to the first virtual asset reference value and the second virtual asset reference value.

The specific method for determining the second virtual asset reference value of the article according to the matching result can be that the association quantity and the quantity threshold value can be matched; if the association number is greater than the number threshold, determining the attribute of the article as a first attribute, and determining the configuration value corresponding to the first attribute as a second virtual asset reference value of the article; and if the association number is smaller than or equal to the number threshold, determining the attribute of the article as a second attribute, and determining the configuration value corresponding to the second attribute as a second virtual asset reference value of the article.

The specific method for determining the virtual asset evaluation reference value of the object according to the first virtual asset reference value and the second virtual asset reference value may be that a first evaluation parameter corresponding to the first virtual asset reference value and a second evaluation parameter corresponding to the second virtual asset reference value may be obtained; multiplying the first virtual asset reference value by a first evaluation parameter to obtain a first operation value; multiplying the second virtual asset reference value by a second evaluation parameter to obtain a second operation value; then, the first operation value and the second operation value can be added to obtain a virtual asset evaluation reference value of the article.

It should be appreciated that, based on the historical repair record and the value prediction model for an item, a first virtual asset reference value for the item may be output, and a repair frequency for the item may be determined based on the historical repair record, the higher the repair frequency, the higher the first virtual asset reference value for the item; the number of the related articles may be the number of the related articles having the same function as the articles, if the number of the related articles having the same function as the articles is larger, the more the related articles having the same function as the articles are, the lower the required degree of the articles is (other related articles can replace the articles), the lower the second virtual asset reference value of the articles is; and if the association number is smaller, that is, the association articles having the same function as the article are also smaller, the more needed the article is (the fewer other association articles that can replace the article are). It should be appreciated that the value obtained by adding the first virtual asset reference value and the second virtual asset reference value may be used as the virtual asset evaluation reference value of the item. It should be appreciated that the value prediction model may be a recurrent neural network model (Recurrent Neural Network, RNN) that may include an input layer that may be used to input data that may be a sequence (e.g., the historical repair record described above), a hidden layer that may be used to extract hidden variables of the input data (e.g., repair features of the historical repair record described above), i.e., to extract hidden features of the input sequence over time, from which a predicted value (e.g., the first asset-seeking reference value) corresponding to the historical repair record may be determined, and an output layer from which the predicted value may be output.

It should be appreciated that the first and second evaluation parameters described above may refer to evaluation weights that may be determined by human experience or by means of machine training.

In the application, after a first user obtains the article from a second user through a trade transaction, the first user can initiate a modification request for the article to request the second user to modify the article. The item delivered by the second user to the first user may be a retrofitted item.

Step S102, calling an intelligent contract according to the refitting request, and generating a refitting asset reference value for the article according to the intelligent contract and the part information; the retrofit asset reference value is used to evaluate a retrofit virtual asset for an item.

In the application, after receiving the refitting request for the article, the blockchain node can automatically calculate and generate the refitting asset reference value according to the refitting request and the part information in the refitting request, wherein the part information can comprise the model of the component parts of the article. The specific method for generating the refitted asset reference value of the article can be that the refitted part of the article can be determined according to the intelligent contract and the model of the component part; wherein the retrofit part can be used to replace a component part; the model of the refitted part is matched with the model of the component part; subsequently, a part virtual asset value of the retrofit part may be obtained, and a retrofit asset reference value for the item is generated based on the part virtual asset value. The specific method for generating the refitted asset reference value for the object according to the virtual asset value of the part can be that the structural feature of the refitted part can be obtained, the structural feature is input into a complexity prediction model, and the refitted complexity corresponding to the structural feature can be output through the complexity prediction model; when the refitting complexity is greater than or equal to the complexity threshold, the refitting additional virtual asset can be obtained, the refitting additional virtual asset and the part virtual asset value are added, and the refitting asset reference value of the article can be obtained; and when the retrofit complexity is less than the complexity threshold, the part virtual asset value may be determined as a retrofit asset reference value for the item.

It should be appreciated that the part virtual asset value may refer to the value of the part itself, while the retrofit additional virtual asset may refer to an additional virtual asset that retrofit the part, the greater the retrofit complexity of the part when the structural features of the part are more complex, the greater the retrofit complexity of the part when the retrofit complexity is greater than a certain threshold (e.g., a complexity threshold), the retrofit additional virtual asset will be generated, and the part virtual asset value plus the retrofit additional virtual asset may be used as the retrofit asset reference value for the part. It should be appreciated that if an item has only one part, then the retrofit asset reference value for that part may be used as the retrofit asset reference value for the item; if there are multiple parts in the article, the retrofitted asset reference values of each part in the article may be added, and the result may be used as the retrofit asset reference value of the article.

Step S103, sending the refitting request and the refitting asset reference value to the second equipment, so that the second equipment determines a target refitting virtual asset matched with the refitting asset reference value based on the refitting request and the refitting asset reference value, and returning a refitting electronic contract comprising the target refitting virtual asset; the target retrofit virtual asset refers to a virtual asset that the first device needs to transfer to the second device when the first contracted time is reached.

In the present application, the blockchain node may send a retrofit request with a retrofit asset reference value to a second device, the second device may retrofit a virtual asset for an item based on the retrofit asset reference value, the second device may generate a retrofit electronic contract based on the target retrofit virtual asset and the first contract time, and return the retrofit electronic contract to the blockchain node.

Step S104, the retrofit electronic contract is sent to the first device, so that the first device returns an asset confirmation message based on the retrofit electronic contract.

In the present application, the blockchain node may send the retrofit electronic contract to the first device, and if the first device is not inconsistent with the retrofit electronic contract, an asset confirmation message may be returned to the blockchain node.

It will be appreciated that if the first device is objecting to the retrofit electronic contract, the first device may modify the retrofit electronic contract (e.g., modify the first contract time), obtain a modified retrofit electronic contract and send the modified retrofit electronic contract to the second device via the blockchain node, and the second device may also modify the retrofit electronic contract. Until after the first device is unobjectionable to the retrofit electronic contract, the first device may send an asset confirmation message to the blockchain node.

Step S105, the asset confirmation message is sent to the second device, so that the second device generates a target asset authority transfer request based on the asset confirmation message, the target refitted virtual asset and the target transaction virtual asset, and returns the target asset transfer request; the target asset authority transfer request is used for requesting to acquire virtual asset data corresponding to the application virtual asset value from the third equipment in a target time period; the value of the applied virtual asset is smaller than or equal to the sum of the target refitted virtual asset and the target transaction virtual asset; the target transaction virtual asset is a virtual asset of an appointed article when the first equipment and the second equipment are used for transaction of the article; the target transaction virtual asset refers to a virtual asset which needs to be transferred to the second device by the first device when the second appointed time is reached; the target time period is earlier than the first contracted time and earlier than the second contracted time.

In the present application, the blockchain node may send an asset acknowledgement message to the second device; while the second device may generate an asset rights transfer request based on the asset validation message and send the asset rights transfer request to the blockchain node, it should be appreciated that upon arrival at the first appointment, the first user needs to retrofit the virtual asset (e.g., 20 ten thousand yuan) to the second user transfer target, that is, the second user has acquisition rights for the 20 ten thousand yuan upon arrival at the first appointment; when the second contract time is reached, the first user needs to transfer the target transaction virtual asset (for example, 100 ten thousand yuan) to the second user, that is, the second user has the acquisition right for the 20 ten thousand yuan when the second contract time is reached; the asset authority transfer request may refer to a request by the second user to transfer the acquisition authority of 120 ten thousand yuan (target transaction virtual asset plus target retrofit virtual asset) to a third user to acquire the virtual asset data corresponding to the applied virtual asset value (e.g., 90 ten thousand yuan) from the third user. That is, the second user requests the third user to acquire the virtual asset data corresponding to the application virtual asset value by using the 120-ten-thousand-element acquisition right as a certificate.

It should be appreciated that the blockchain may receive an asset rights transfer request for the item returned by the second device based on the asset confirmation message; the asset authority transfer request comprises a transaction electronic contract, a refitted electronic contract and an application virtual asset value of the first equipment and the second equipment aiming at the object; wherein the application virtual asset value is determined by the second device based on the target retrofit virtual asset and the target transaction virtual asset; the application virtual asset value is less than or equal to the sum of the target retrofit virtual asset and the target trade virtual asset, for example, the target retrofit virtual asset is 50 ten thousand yuan and the target trade virtual asset is 100 ten thousand yuan, then the application virtual asset value can be any value greater than 0 and less than (or equal to) 150 ten thousand yuan; then, the blockchain node can generate transaction confirmation prompt information aiming at the transaction electronic contract and the refitted electronic contract according to the intelligent contract, and the transaction confirmation prompt information is sent to the first equipment; if the first device does not have objection to the transaction electronic contract and the refitting electronic contract, the first device confirms that the transaction electronic contract and the refitting electronic contract are signed between the first device and the second device, and the first device can return confirmation transaction information to the block chain link point; the regional chain node can receive confirmation transaction information returned by the first equipment based on the transaction confirmation prompt information, and determine the recommended application virtual asset value of the article according to the confirmation transaction information, the target refitted virtual asset and the target transaction virtual asset; the recommended application virtual asset value may then be sent to the second device to cause the second device to return a target asset rights transfer request based on the recommended application virtual asset value.

Wherein, for the virtual asset value of the recommended application of the article according to the virtual asset yield, the target refitted virtual asset and the target transacted virtual asset, the specific method may be that confirmation transacting information is sent to the third device; receiving an intermediate electronic contract returned by the third equipment based on the confirmation transaction information; the intermediate electronic contract includes an asset rights transfer confirmation message, a target time period, and a virtual asset yield; the target time period refers to a time range in which the third device expects to transfer virtual asset data corresponding to the application virtual asset value to the device account of the second device; the virtual asset rate is used to determine additional virtual assets that the third device desires to obtain from the second device; and sending the intermediate electronic contract to the second equipment, receiving a first contract confirmation message returned by the second equipment based on the intermediate electronic contract, and determining the recommended application virtual asset value of the article according to the first contract confirmation message, the virtual asset yield, the target refitted virtual asset and the target transaction virtual asset.

The specific method for determining the recommended application virtual asset value of the article according to the first contract confirmation message, the virtual asset yield, the target refitted virtual asset and the target transaction virtual asset can be that according to the first contract confirmation message, an intelligent contract is called, and the target refitted virtual asset and the target transaction virtual asset are added through the intelligent contract to obtain the operation virtual asset; according to the intelligent contract, calculating the virtual asset and the yield of the virtual asset, determining the value of the recommended application virtual asset; wherein the sum of the recommended application virtual asset value and the additional virtual asset value is equal to the calculated virtual asset; the additional virtual asset value is obtained by calculating the intelligent contract and the virtual asset rate.

It should be appreciated that the second user and the third user (virtual asset provider, corresponding to the third device) may agree on an additional virtual asset yield (i.e., the virtual asset yield described above) for the applied virtual asset value. By calculating the additional virtual asset yield and the calculated virtual asset (the sum of the target transaction virtual asset and the target modification virtual asset), the additional virtual asset value can be determined, that is, after the third user transfers the virtual asset data corresponding to the applied virtual asset value (for example, 90 ten thousand yuan) to the second user, the second user should repay the virtual asset data corresponding to the applied virtual asset value (90 ten thousand yuan) and the additional virtual asset value (for example, 9 ten thousand yuan) to the third user when the first contract time (or the second contract time) is reached. Because the second user uses the total virtual asset value of the target transaction virtual asset and the target modification virtual asset as a guarantee, so that the user who actually pays back is the first user (the first user transfers the total virtual asset value of the target transaction virtual asset and the target modification virtual asset to the third user), the blockchain node can calculate a recommended application virtual asset value based on the additional virtual asset yield agreed between the second user and the third user and the total virtual asset value of the target transaction virtual asset and the target modification virtual asset (operation virtual asset), so that the sum of the recommended application virtual asset value and the additional virtual asset value is just equal to the operation virtual asset. That is, the first user transfers to the third user's computing virtual asset just enough to repay the application virtual asset value and the additional virtual asset value. For example, the blockchain node may automatically calculate a recommended application virtual asset value from the additional virtual asset yield such that the sum of the recommended application virtual asset value (e.g., 110 ten thousand yuan) and the additional virtual asset value (e.g., 10 ten thousand yuan) is equal to the sum of the target transaction virtual asset and the target retrofit virtual asset (e.g., 120 ten thousand yuan). And the blockchain node may send the recommended application virtual asset value to the second device, and if the second device is not inconsistent with the recommended application virtual asset value, the second device may generate a target asset rights transfer request based on the recommended application virtual asset value and send the target asset rights transfer request to the blockchain node.

And step S106, the target asset authority transfer request is sent to the third device, so that the third device transfers the virtual asset data corresponding to the applied virtual asset value to the second device in the target time period based on the target asset authority transfer request.

In the application, the blockchain node can send the target asset authority transfer request to the third device, and the third device can determine whether to transfer the virtual asset data corresponding to the application virtual asset value to the second device after receiving the target asset authority transfer request, if yes, the third device can jointly agree with the second device through the blockchain node to agree with the target time period, and transfer the virtual asset data corresponding to the application virtual asset value to the second device in the target time period.

It should be understood that the first device, the second device, and the third device in the present application may be all user terminals, and the first device may be any user terminal in the user terminal cluster in the embodiment corresponding to fig. 1, for example, the user terminal is the user terminal 10a; the second device may be any user terminal in the user terminal cluster in the embodiment corresponding to fig. 1, for example, the user terminal is the user terminal 10b; the third device may be any user terminal in the user terminal cluster in the embodiment corresponding to fig. 1, for example, the user terminal is the user terminal 10c.

It should be appreciated that in a gaming scenario, after player 1 and player 2 have made a trade electronic contract with player 1 for a game accessory or play item that is an item (e.g., an airplane part) (player 2 should pay player 1 for a target trade virtual asset 40 medal when the first appointment time is reached); player 2 may then delegate player 1 to retrofit the aircraft component. Player 2 may initiate a retrofit request for the item, the blockchain node may automatically calculate a retrofit asset reference value based on the part information of the aircraft item, and send the retrofit asset reference value to player 1, which player 1 may determine a target retrofit virtual asset (e.g., 20 game pieces) for the item based on the retrofit asset reference value. When both player 1 and player 2 are not contemplating the target retrofit virtual asset, a retrofit electronic contract may be entered (player 2 should pay player 1 for target retrofit virtual asset 20 medals when the second contract time is reached). Subsequently, player 1 may initiate an asset entitlement transfer request for a game accessory or play object, such as an item (airplane part), based on the target retrofit virtual asset 20 token, and the target trade virtual asset 40 token, to obtain virtual asset data for applying for a virtual asset value (e.g., 30 tokens) from a provider of the virtual asset (virtual currency such as game medals, game experience values, game credits, and game diamonds); it should be appreciated that, the user information in the game scenario may refer to player information, where the player information may include game behavior data (e.g., online time, floor data, performance data, reported data, complaint data, registration information, a party to which the player belongs, a game system to which the player belongs, etc.) of the player, after the player initiates the asset authority transfer request, the blockchain node may obtain the player information of the player, based on the player information, the blockchain node may calculate a reliability evaluation value of the player, after the reliability evaluation value reaches a reliability threshold, the blockchain node may obtain registration information (e.g., age, gender, etc.) of the player, and when the registration information satisfies a reliability condition (e.g., age over 16 years), the blockchain node may perform subsequent processing on the asset authority transfer request of player 1. For example, the blockchain node may send to the player 2 contract information to be validated (validation information for trading electronic contracts and retrofitting electronic contracts), upon receiving the validation transaction information sent by the player 2, the blockchain node may send the validation transaction information and the asset entitlement transfer request to a virtual asset provider (e.g., a gaming platform), from which the virtual asset provider may determine that the trade and the retrofitting transaction are actually present between the player 1 and the player 2 (i.e., that the target trading virtual asset is reliable with the target retrofitting virtual asset); after agreeing to provide player 1 with virtual asset data (e.g., 30 tokens) corresponding to the application virtual asset value, the virtual asset provider may agree with player 1 via the blockchain node to a target time period (earlier than the first agreed time and earlier than the second agreed time), and transfer the 30 tokens to player 1 in the target time period. Further, after the player 1 receives 30 tokens, the blockchain node may send an asset receipt acknowledgement message to the blockchain node, and the blockchain node may send the asset receipt acknowledgement message to the player 2, and the player 2 may transfer the target transaction virtual asset to the virtual asset provider when the first contract time is reached, and transfer the target retrofit virtual asset to the virtual asset provider when the second contract time is reached (or the player 2 may transfer the target retrofit virtual asset to the virtual asset provider together with the target transaction virtual asset when the first contract time or the second contract time is reached).

In the embodiment of the application, after the first equipment acquires the article through transaction at the second equipment, the first equipment can initiate a modification request for the article, and after receiving the modification request for the article, the data (part information) of the article can be stored in the blockchain, and the authenticity and the reliability of the part information of the article can be ensured because the blockchain is provided with anti-counterfeiting property and non-tamper property, so that the reliability can be provided for a modification asset reference value which is automatically generated subsequently based on the part information, and the second equipment can quickly and accurately determine a target modification virtual asset of the article based on the reliable modification asset reference value, thereby improving the execution efficiency of modification service of the article; moreover, the second device can initiate a target asset permission transfer request based on the target refitted virtual asset and the target transaction virtual asset of the object, quickly acquire virtual asset data corresponding to the application virtual asset value from the third device, and apply the target refitted virtual asset and the target transaction virtual asset of the object and the blockchain to the asset permission transfer service of the object, so that the second device does not need to wait for the first device to transfer the target refitted virtual asset or the target transaction virtual asset at the appointed time, but acquires corresponding virtual asset data in advance from the third party to complete the exchange of the resource data, thereby improving the execution success rate of the transaction service. In conclusion, the application can improve the execution efficiency and success rate of transaction service.
