Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.
In order to facilitate understanding of the technical process of the embodiments of the present application, some terms related to the embodiments of the present application are explained below:
blockchain (Block chain): is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and the like. The blockchain is essentially a de-centralized database, which is a series of data blocks generated by cryptographic association, each data block containing information of a network transaction for verifying the validity (anti-counterfeiting) of the information and generating a next block, each block containing a time stamp and a link to the previous block. In a narrow sense, a blockchain is a chain data structure that combines blocks of data in a sequential manner in time order, and cryptographically guaranteed, non-tamperable and non-counterfeitable, distributed ledgers, i.e., the data in the blockchain will be irreversible once recorded.
Consensus mechanism (Consensus mechanism): is a mathematical algorithm for realizing trust establishment and rights acquisition among different nodes in a block chain system. In a blockchain system, the verification and confirmation of a transaction can be completed in a short time through voting of special nodes, and if a plurality of nodes with irrelevant interests can reach consensus for one transaction, all the nodes in the system can be considered to reach consensus for the same.
Smart contract: is a computer protocol that aims to propagate, verify or execute contracts in an informative manner. Each node in the blockchain system can operate the data stored on the chain according to the contract program automatically executed by the specific condition, and is an important way for users to interact with the blockchain and realize business logic by using the blockchain. The purpose of smart contracts is to provide a secure method over traditional contracts and reduce other transaction costs associated with the contracts, which allows trusted transactions to be conducted without third parties, which transactions are traceable and irreversible.
Public key (public key) and private key (private key): is a key pair (i.e., a public key and a private key) obtained by an algorithm, the public key being the public part of the key pair and the private key being the non-public part. The public key is typically used to encrypt a session key, verify a digital signature, or encrypt data that may be decrypted with a corresponding private key. The key pair obtained by this algorithm can be ensured to be unique. When using such a key pair, if a piece of data is encrypted with one of the keys, it must be decrypted with the other key. For example, encrypting data with a public key must be decrypted with a private key, and if encrypted with a private key must also be decrypted with a public key, otherwise decryption will not succeed.
Fig. 1 is a schematic diagram of an implementation environment of a resource processing method according to an embodiment of the present application, and referring to fig. 1, the implementation environment may include a terminal 100, a server 110, and a blockchain system 120.
The terminal 100 may be, but is not limited to, a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, etc. The terminal 100 may be a terminal used by any user, and the terminal 100 is installed and operated with a client of a target transaction platform, where the target transaction platform may support a virtual resource transaction, and the virtual resource may be a financial product or the like. For example, an account of any user may be logged into a client of a target transaction platform running in the terminal 100, and the any user may transfer or purchase virtual resources such as financial products through the target transaction platform. The terminal 100 may refer broadly to one of a plurality of terminals, and the present embodiment is illustrated by the terminal 100 only.
The server 110 may be a background server of the target trading platform, and the server 110 may be configured to process trading data generated during a virtual resource trading process. The server 110 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs (Content Delivery Network, content delivery networks), basic cloud computing services such as big data and artificial intelligence platforms, and the like.
The blockchain system 120 may include a plurality of node devices 1201, and the node devices 1201 may be any form of computer device in a network, such as servers, hosts, user terminals, etc. Data can be shared from node device 1201 to node device 1201, i.e., each node device 1201 can collectively maintain a blockchain in the blockchain system 120. Among other things, the node devices 1201 may establish a P2P network based on a Peer-To-Peer (P2P) protocol. The P2P protocol is an application layer protocol that runs on top of the transmission control protocol (Transmission Control Protocol, TCP) protocol. Each node device 1201 may receive input information during normal operation and maintain shared data within the blockchain system 120, i.e., maintain blockchains in the blockchain system 120, based on the received input information. To ensure interworking of information within the blockchain system 120, an information connection may exist between each node device 1201 in the blockchain system 120, and information may be transferred between the node devices 1201 through the information connection. For example, when any node device in the blockchain system receives input information, other node devices in the blockchain system may also acquire the input information, and store the input information as data in the shared data, so that the data stored on all node devices in the blockchain system are consistent. In an embodiment of the present application, the node device 1201 may obtain transaction data sent by the server 120, process the transaction data, and record a transaction process of the virtual resource.
In the embodiment of the present application, the terminal 100 and the server 110 may be registered as node devices in the blockchain system 120. The terminals 100, the server 110 and the blockchain system 120 may be directly or indirectly connected through wired or wireless communication to implement data transmission.
Those skilled in the art will appreciate that the number of terminals, servers, and node devices may be greater or lesser. The embodiment of the application does not limit the number and the device types of the terminal, the server and the node devices.
According to the technical scheme provided by the embodiment of the application, the target virtual resource with a certain value can flow among all users in a ownership transfer mode, so that all users holding the target virtual resource in different time periods can obtain reasonable benefits. For example, in the financial field, the target virtual resource may be a periodic financial product issued by a financial institution, and in a normal case, after a user purchases the periodic financial product, that is, the target virtual resource needs to be held for a fixed holding period, so that a higher profit can be obtained, and if an asset put into the target virtual resource is collected in advance, the obtained profit is greatly reduced. By combining the technical scheme provided by the embodiment of the application, the holding user of the target virtual resource can transfer the ownership of the target virtual resource within a fixed holding period, and the assigned user of the ownership continuously holds the target virtual resource. That is, the target virtual resource is held by the user for the fixed holding period, and the asset which is put into the target virtual resource does not need to be withdrawn. In this case, the users holding the target virtual resource in different time periods can obtain higher benefits, and the fluidity of the target virtual resource can also be improved.
Fig. 2 is a flowchart of a resource processing method according to an embodiment of the present application, as shown in fig. 2, the method may be applied to a node device of a blockchain system, and the method may specifically include the following steps:
201. an ownership-assigned request is received, the ownership-assigned request carrying a user identification of a user to be assigned, a resource identification of a target virtual resource to which the request is assigned, and an intelligent contract identification.
The target virtual resource may be any type of financial product, for example, a periodic financial product, and may be traded in a target trading platform. The to-be-assigned user is the user who will acquire ownership of the target virtual resource, i.e., the sending user of the ownership-assigned request.
The target virtual resource can be yielded by the user to which the source belongs, namely, the user currently owning the ownership of the target virtual resource can be yielded by the user to which the source belongs, and the source can send an ownership transfer request for the target virtual resource to node equipment in the blockchain system through the client of the target transaction platform so as to transfer the ownership of the target virtual resource. And the node equipment responds to the ownership transfer request and issues transfer information of the target virtual resource in the block chain system, and other users of the target transaction platform can acquire the transfer information issued in the block chain system.
After the to-be-assigned user obtains the transfer information of the target virtual resource through the client of the target transaction platform, after determining that the ownership of the target virtual resource needs to be transferred, an ownership assigned request can be sent to the node device to obtain the ownership of the target virtual resource.
202. And responding to the target intelligent contract indicated by the contract identification, and acquiring the user information of the user to be assigned and the resource information of the target virtual resource from a blockchain of a blockchain system based on the user identification of the user to be assigned and the resource identification of the target virtual resource.
Wherein the target smart contract may be used to indicate data processing logic during an ownership transaction of the target virtual resource, and may include processing logic for ownership transfer requests and processing logic for ownership assigned requests.
In the embodiment of the application, the blockchain of the blockchain system can store the user information of each user of the target transaction platform and the resource information of each virtual resource. After receiving the ownership grant request, the node device may invoke the target intelligent contract indicated by the contract identifier, and acquire the usage information and the resource information from the blockchain through the target intelligent contract, so as to perform subsequent user authentication to be granted and target virtual resource authentication based on the user information and the resource information. Because the data stored in the blockchain is not tamperable and not deletable, the accuracy and comprehensiveness of acquiring the user information and the resource information can be ensured, and the influence on the follow-up authentication process of the user to be assigned and the target virtual resource authentication process caused by inaccurate data is avoided.
203. Based on the user information and the resource information, verifying the assigned qualification of the user to be assigned and the target virtual resource to obtain a verification result.
The assigned qualification refers to that the to-be-assigned user needs to satisfy the assigned condition of the target virtual resource, for example, when the number of virtual currencies contained in the account of the to-be-assigned user is greater than or equal to the number of virtual currencies corresponding to the target virtual resource, the to-be-assigned user has the assigned qualification of the target virtual resource, that is, sufficient assets are needed in the account of the to-be-assigned user to purchase the target virtual resource. Of course, it may also be determined whether the to-be-assigned user has the assigned qualification based on other information, for example, whether the user information of the to-be-assigned user includes a bad transaction record, which is not limited in the embodiment of the present application.
In the embodiment of the present application, verifying the target virtual resource may include verifying the validity to which the target virtual resource belongs, that is, verifying whether the ownership user of the target virtual resource is the user to which the source belongs; verifying the transaction status of the target virtual resource, i.e., verifying whether the target virtual resource is transactable, may be included. Of course, the virtual resource may be verified in other aspects, which are not limited by the embodiment of the present application.
In the technical scheme, the user qualification of the user to be assigned and the target virtual resource are verified, so that the ownership assigned request can be ensured to be effective, and illegal transactions are avoided.
204. And responding to the assigned qualification of the user to be assigned and the verification result of the target virtual resource, and executing the operation corresponding to the verification result in the target intelligent contract.
In the embodiment of the present application, if the assigned qualification of the to-be-assigned user and the verification of the target virtual resource pass, virtual money transfer may be performed in the blockchain system, and the virtual money corresponding to the target virtual resource may be transferred from the account of the to-be-assigned user to the account of the user to which the target virtual resource originally belongs. That is, the user to be assigned pays a certain amount of virtual money to the original user of the target virtual resource to purchase the target virtual resource, and obtains ownership of the target virtual resource. The virtual currency number corresponding to the target virtual resource can be set by the user to which the target virtual resource belongs. In one possible implementation, the node device may also store an ownership transfer record in the blockchain, and in particular, the node device may package the ownership transfer record and other transaction information into a block, consensus the block by each node device in the blockchain system, and add the block to the tail of the blockchain in response to the block being consensus. The ownership transfer record may be used to record that the ownership of the target virtual resource is updated from the original user to the to-be-assigned user, where the ownership transfer record may include information such as a resource identifier of the target virtual resource, a user identifier of the original user, a user identifier of the to-be-assigned user, a virtual currency number corresponding to the target virtual resource, and a timestamp.
In the embodiment of the application, if any one of the assigned qualification of the to-be-assigned user and the target virtual resource is verified to be not passed, the block chain system can output transfer refusal information, and the block chain system can feed back the result of transaction failure to the to-be-assigned user.
The above embodiment is merely a brief description of an embodiment of the present application, where the technical solution provided by the embodiment of the present application is to obtain, from a blockchain of a blockchain system, user information of a to-be-assigned user and resource information of a target virtual resource in response to an ownership-assigned request for the target virtual resource, and since data stored in the blockchain is indelible and untampered, it is possible to ensure accuracy of obtaining the user information and the resource information, and therefore, based on the user information and the resource information, the feasibility and legality of the present assignment can be determined by verifying the assigned qualification of the to-be-assigned user and the target virtual resource, virtual money transfer is performed in the blockchain system in response to the passing of the assigned qualification of the to-be-assigned user and the verification of the target virtual resource, ownership record of the target virtual resource is stored in the blockchain, and the ownership of the target virtual resource is updated from the original to the to-be-assigned user, so as to implement the target virtual resource assignment, and the above assignment step is performed based on the blockchain, and the security of the target virtual resource assignment can be improved.
The above embodiment describes a process that a to-be-assigned user obtains ownership of a target virtual resource, where the target virtual resource may be a virtual resource that is yielded by a user to which the to-be-assigned user belongs, and a process that the to-be-assigned user transfers ownership of the target virtual resource is shown in fig. 3. Fig. 3 is a flowchart of a resource transfer method according to an embodiment of the present application, where the method may be applied in the implementation environment shown in fig. 1, and referring to fig. 3, the method may specifically include the following steps:
301. the first terminal sends an ownership transfer request for the target virtual resource to the server.
The first terminal may be a terminal used by a user to which the target virtual resource belongs, where the user to which the target virtual resource belongs may transfer ownership of the target virtual resource through a client of a target transaction platform running in the first terminal. The server may be a background server of the target transaction platform, and the server may process data generated by a client of the target transaction platform. In the embodiment of the application, the virtual resource can be a financial product issued by a financial institution such as a bank.
In the embodiment of the present application, the ownership transfer request may carry a user identifier of the user to which the source belongs, a resource identifier of the target virtual resource, and transfer information of the target virtual resource. The user identifier may be used to uniquely indicate a user, and the user identifier may be represented by a document number, an account address, or the like, which is not limited by the embodiment of the present application. The resource identification may be used to uniquely indicate a virtual resource. The transfer information of the target virtual resource may include a transfer interest rate of the target virtual resource, a virtual currency number corresponding to the target virtual resource, and a transfer share of the target virtual resource. The transfer interest rate of the target virtual resource and the transfer share of the target virtual resource may be set by the user to whom the source belongs, and the virtual currency number corresponding to the target virtual resource, that is, the virtual currency number paid by the user to purchase the target virtual resource, may be determined based on the transfer interest rate of the target virtual resource and the transfer share of the target virtual resource. Of course, the transfer information of the target virtual resource may also include information such as remaining holding time of the target virtual resource, which is not limited in the embodiment of the present application.
In one possible implementation manner, the first terminal may display a detail page of the target virtual resource, referring to fig. 4, and fig. 4 is a schematic diagram of a detail page provided by an embodiment of the present application, where the detail page may include an information display area 401 of the target virtual resource and a transfer control 402. Taking the target virtual resource as a periodic financial product as an example, the information display area 401 may display information such as a holding period, a deposit time, an expiration time, an interest rate, and a total interest of the periodic financial product. When the first terminal detects the triggering operation of the transfer control 402 by the original user, the first terminal may display a transfer page of the target virtual resource, where the transfer page is used to collect transfer information of the target virtual resource.
Referring to fig. 5, fig. 5 is a schematic diagram of a transfer page provided in an embodiment of the present application, where the transfer page may include a transfer share display area 501, a transfer interest rate setting area 502, an information display area 503, and a confirmation control 504. The transfer share display area 501 may display the total share of the target virtual resource held by the user to which the source belongs, that is, the user to which the source belongs needs to transfer all the shares held in the current virtual resource transfer process. Of course, the user to whom the source belongs may set the transfer share, and only a part of the share is transferred in a virtual resource transfer process, which is not limited in the embodiment of the present application, and in the embodiment of the present application, only the transfer of all the shares is described as an example. In the embodiment of the present application, the primary user may set the transfer interest rate of the target virtual resource in the transfer interest setting area 502 based on the interest rate interval corresponding to the target virtual resource, and the first terminal may determine the virtual currency number corresponding to the target virtual resource in the current resource transfer process based on the transfer interest rate set by the primary user and the transfer share. The interest rate interval corresponding to the target virtual resource may be set by the issuing mechanism of the target virtual resource, different virtual resources may correspond to different interest rate intervals, and in one possible implementation manner, for one virtual resource, multiple interest rate intervals may be set based on the remaining holding time length of the virtual resource, that is, different remaining holding time lengths correspond to different interest rate intervals, for example, when the remaining holding time length of the target virtual resource is less than or equal to 2 years, the transfer interest rate may be set in the first interest rate interval, and when the remaining holding time length of the target virtual resource is greater than 2 years, the transfer interest rate may be set in the first interest rate interval. In one possible implementation, the higher the transfer interest rate set by the former affiliated user, the higher the income obtained by the assignee user after purchasing the target virtual resource, and the greater the number of virtual currencies corresponding to the target virtual resource determined based on the transfer interest rate already in the transfer share, that is, the greater the number of virtual currencies paid by the assignee user for purchasing the target virtual resource. It should be noted that the above description of the relationship between the virtual currency number corresponding to the target virtual resource and the transfer interest rate and the transfer share is merely an exemplary description, and the embodiment of the present application does not limit what kind of calculation method is specifically adopted to determine the virtual currency number corresponding to the target virtual resource. When the first terminal detects the triggering operation of the confirmation control 504 by the original user, information such as the share, the interest rate, the number of virtual currencies corresponding to the target virtual resource and the like collected by the transfer page can be obtained as transfer information of the target virtual resource, and an ownership transfer request of the target virtual resource is generated based on the transfer information.
The first terminal may send an ownership transfer request of the target virtual resource to a background server of the target transaction platform, and the server performs data processing based on the ownership transfer request.
302. The server validates the target virtual resource and transfer information of the target virtual resource in response to the ownership transfer request for the target virtual resource.
In one possible implementation, the server may initially verify the target virtual resource and transfer information for the target virtual resource based on data stored in a local database. The local database may store user information of each user and resource information of each virtual resource in the target transaction platform. For example, the server may obtain, from the local data, user information of the user to which the source belongs based on the user identifier of the user to which the source belongs, and verify whether the virtual resource held by the user to which the source belongs includes the target virtual resource, that is, verify whether the ownership user of the target virtual resource is the target user; based on the resource identification of the target virtual resource, acquiring resource information of the target virtual resource from a local database, wherein the resource information can comprise information such as interest rate interval and transaction state corresponding to the target virtual resource, and the server can compare transfer information of the target virtual resource with the resource information to verify whether the transfer interest rate of the target virtual resource is in the interest rate interval or not and verify whether the target virtual resource is in a tradable state or not. The above description of the verification method of the target virtual resource and the transfer information is merely an exemplary description, and the embodiment of the present application is not limited to the specific verification method adopted.
If the target virtual resource and the transfer information of the target virtual resource are both verified, the server may continue to execute the following step 303; if any one of the verification of the target virtual resource and the transfer information of the target virtual resource fails, the server does not need to execute the following step 303, and the server may feed back the transaction failure information to the user to which the source belongs.
303. Responsive to the target virtual resource and verification of transfer information of the target virtual resource passing, the server sends an ownership transfer request of the target virtual resource to a node device in the blockchain system.
In an embodiment of the present application, after determining that the target virtual resource and the transfer information of the target virtual resource pass verification, the server may broadcast the ownership transfer request to each node device of the blockchain system, and each node device verifies whether the ownership transfer request is valid based on the data in the blockchain, that is, performs step 304 described below.
In the embodiment of the application, the target virtual resource and the transfer information are initially verified based on the information stored in the local database of the server, namely whether the ownership transfer transaction of the target virtual resource is legal or not is initially verified, after the server passes the verification, the ownership transfer request is sent to the block chain system, and the block chain system performs the verification again. The server performs preliminary screening on ownership transfer transactions, so that the data processing capacity of the block chain system can be reduced, and invalid operation of the block chain is avoided. Of course, the server may also directly send the received ownership transfer request to the blockchain system, which is not limited in this embodiment of the present application.
304. The node equipment acquires user information of the original user and resource information of the target virtual resource from the blockchain, and verifies the validity of the ownership transfer request based on the acquired user information, resource information and transfer information of the target virtual resource.
Taking a node device to verify the ownership transfer request as an example, in one possible implementation manner, the ownership transfer request may carry a contract identifier of a target smart contract, the node device may invoke the target smart contract based on the contract identifier, obtain user information of the original user and resource information of the target virtual resource based on the target smart contract, and perform a subsequent verification step of the ownership transfer request based on the obtained information. In the embodiment of the application, the node equipment can verify whether the ownership of the original user to the target virtual resource is valid or not based on the user information of the original user and the resource information of the target virtual resource; verifying whether transfer information of the target virtual resource is valid based on resource information of the target virtual resource; based on the transaction state information in the resource information of the target virtual resource, verifying whether the target virtual resource is in a tradable state. And determining that the ownership transfer request is valid in response to the ownership of the target virtual resource by the original affiliated user being valid, the transfer information of the target virtual resource being valid, and the target virtual resource being in a tradable state. The verification process is the same as the verification process of the target virtual resource and the transfer information in step 302, and will not be described herein.
In one possible implementation, the node device may also verify a digital signature carried by the ownership transfer request. For example, the first terminal and the server may each be registered in the blockchain system, and public and private keys are assigned to the first terminal and the server by the blockchain system. When the first terminal sends the ownership transfer request to the server, a private key signature of the first terminal can be added in the ownership transfer request, after the server receives the ownership transfer request, a public key of the first terminal can be applied to match with the private key signature, and if the matching is successful, the ownership transfer request can be determined to be valid; similarly, when the server sends the ownership transfer request to the node device, a private key signature of the ownership transfer request may be added to the ownership transfer request, and after the node device receives the ownership transfer request, the public key of the server may be applied to verify the ownership transfer request.
It should be noted that the above description of the method for verifying the target virtual resource and the transfer information by the node device is merely an exemplary description, and the embodiment of the present application is not limited to what verification method is specifically adopted. If the ownership transfer request verifies, the server may proceed to step 305, described below; if the ownership transfer request fails to verify, the server does not need to perform the following step 305, and the server may feed back the transaction failure information to the user to whom the source belongs.
It should be noted that, in the steps 302, 303, and 404, in response to the target intelligent contract indicated by the contract identifier, the user information of the user to which the source belongs and the resource information of the target virtual resource are obtained from the blockchain based on the user identifier of the user to which the source belongs and the resource identifier of the target virtual resource; and verifying the validity of the ownership transfer request based on the user information of the user to which the source belongs, the resource information of the target virtual resource and the transfer information of the target virtual resource. In the embodiment of the application, the data stored in the blockchain is undeletable and untampereable, so that the node equipment can be ensured to acquire the comprehensiveness and accuracy of the user information and the resource information, the accuracy of a verification result can be further ensured, the validity of an ownership transfer request is ensured, and the condition of illegal transaction is avoided.
305. Responsive to the ownership transfer request verifying, the node device issues transfer information for the target virtual resource in the blockchain system.
In one possible implementation, after determining that the ownership transfer request passes, the node device in the blockchain system may feed back the verification result to the server, and the server modifies the resource information in the local database, for example, may modify the transaction state of the target virtual resource to be a state to be assigned. After the modification of the resource information of the target virtual resource by the server is completed, a release request for the target virtual resource can be sent to the blockchain system, and the node equipment in the blockchain system executes the step of releasing the target virtual resource.
In one possible implementation manner, the node device may add the transfer information of the target virtual resource to a transaction list of a target transaction platform in the blockchain system, and in an embodiment of the present application, the node device may maintain a transaction list of at least one transaction platform, where the transaction list may be used to store transfer information of each virtual resource to be assigned in each transaction platform. In the embodiment of the present application, the node device also needs to update the transaction status of the target virtual resource in the blockchain system. For example, first, the node device may generate a transaction state update record, where the transaction state update record may include information that the target virtual resource is in a state to be assigned; then, storing the transaction state update record into a memory pool, and packaging data in the memory pool based on a target period to construct a block; finally, based on the consensus mechanism, the latest constructed block is added to the tail of the blockchain to finish updating the transaction state. The memory pool may be used to store data that is not uplink in the blockchain system, and the target period may be set by a developer. In one possible implementation, the updating of the transaction state may be accomplished based on a target smart contract, i.e., in response to the ownership transfer request verifying, the node device may invoke a target smart contract in the blockchain system, by which the transaction state of the target virtual resource is set to a to-be-assigned state.
The above description of the transfer information distribution method of the target virtual resource is merely an exemplary description, and the embodiment of the present application is not limited to what kind of transfer information distribution method is specifically adopted.
In the embodiment of the application, the transfer information of the target virtual resource is recorded by the blockchain system by modifying the transaction state information of the target virtual resource in the blockchain system, so that the transfer information is prevented from being tampered, and the real and effective ownership transfer transaction is ensured.
306. And the node equipment sends the target virtual resource release result to the server.
In the embodiment of the application, after the blockchain system completes the release of the target virtual resource, the release result of the target virtual resource can be fed back to the server.
In response to successful release of the target virtual resource in the blockchain system, the server may perform data synchronization based on the transaction list corresponding to the target transaction platform, that is, the server may update display information of a transaction display page of the target transaction platform based on the transaction list, add transfer information of the target virtual resource in the transaction display page, and the first terminal may display the transfer information of the target virtual resource in a link or hyperlink form on the transaction display page. Referring to fig. 6, fig. 6 is a schematic diagram of a transaction notification page according to an embodiment of the present application. The page may display transfer information 601 of the target virtual resource transferred by the user to which the source belongs, or may display transfer information of the virtual resource transferred by another user. In one possible implementation manner, the server may further send a prompt message that the target virtual resource is successfully issued to the first terminal, where the prompt message may be displayed in the first terminal in a form of a short message or a push message. The prompt information may further include a link of the release success page, and the first terminal may display the release success page when detecting a click operation of the link by the user to which the first terminal belongs. Fig. 7 is a schematic diagram of a successful release page according to an embodiment of the present application, where the successful release page may include an information display area 701, where the information display area 701 may display the share of the target virtual resource to be transferred, the rate of interest to be transferred, the number of virtual currencies corresponding to the target virtual resource, and the effective time of the current transfer transaction. The valid time of the transfer transaction may be set to seven days, and if the target virtual resource is not yielded within seven days, the blockchain system may delete the transfer information of the target virtual resource from the transaction list of the target transaction platform, the transaction public page may not display the transfer information of the target virtual resource any more, and the original affiliated user may initiate an ownership transfer request for the target virtual resource again.
And responding to the failure of the release of the target virtual resource in the blockchain system, the server can send prompt information of the failure of the release of the target virtual resource to the first terminal, and the first terminal displays the prompt information of the failure of the release so as to prompt the user to which the source belongs to resubmit the release request of the target virtual resource.
In the embodiment of the application, the original user of the target virtual resource can transfer the ownership of the target virtual resource, and the target virtual resource can flow in an ownership transfer mode, so that partial benefits are obtained in advance. For example, when the target virtual resource is a periodic financial product, the user can transfer the periodic financial product in a holding period, and different users can hold the periodic financial product in different time periods, so that the mobility of the periodic financial product is improved under the condition of taking a guarantee benefit.
The above embodiments mainly describe a process of publishing a target virtual resource to be yielded in a blockchain system, and in the embodiments of the present application, each user may purchase a virtual resource transferred by another user to obtain ownership of the virtual resource. Fig. 8 is a flowchart of a resource assigning method according to an embodiment of the present application, where the method may be applied in the implementation environment shown in fig. 1, and referring to fig. 8, the method may specifically include the following steps:
801. The second terminal sends an ownership-granted request for the target virtual resource to the server.
The second terminal may be a terminal used by a to-be-assigned user of the target virtual resource, where the to-be-assigned user may purchase the target virtual resource through a client of a target transaction platform running in the second terminal, and acquire ownership of the target virtual resource. In the embodiment of the application, the ownership assigned request can carry information such as user identification of the user to be assigned, resource identification of the target virtual resource to be assigned by the request, and the like.
In one possible implementation, the second terminal may display a transaction notification page of the target transaction platform, where transfer information of the target virtual resource may be displayed in the form of a hyperlink. And when the second terminal detects clicking operation of the hyperlink corresponding to the transfer information of the to-be-assigned user on the target virtual resource, displaying a transaction detail page of the target virtual resource. Fig. 9 is a schematic diagram of a transaction detail page provided in an embodiment of the present application, and referring to fig. 9, the transaction detail page may include an information display area 901 and a purchase control 902, where the information display area may display transfer information of the target virtual resource, for example, may display information of a transfer share, a transfer rate, an effective time of the current transfer transaction, and the like of the target virtual resource. When the second terminal detects the click operation of the purchase control by the to-be-assigned user, the resource identifier of the target virtual resource and the user identifier of the current login user in the client, namely the user identifier of the to-be-assigned user, can be obtained, and the ownership assigned request of the target virtual resource is generated based on the resource identifier of the target virtual resource and the user identifier of the to-be-assigned user.
The second terminal can send the ownership assigned request of the target virtual resource to a background server of the target transaction platform, and the server processes data based on the ownership assigned request.
802. The server initially verifies the ownership assigned request in response to the ownership assigned request for the target virtual resource.
In one possible implementation, after the server receives the ownership assigned request, the server may initially verify assigned qualifications of the target virtual resource and the to-be-assigned user based on data stored in a local database. For example, the server may obtain, from a local database, user information of the to-be-assigned user based on the user identifier of the to-be-assigned user, and further obtain the number of virtual currencies included in the target account of the to-be-assigned user, to determine whether the virtual currencies of the to-be-assigned user are sufficient, that is, whether funds for the to-be-assigned user to purchase the target virtual resource are sufficient. The target account may be one account or a plurality of accounts, for example, the publishing platform of the target virtual resource may limit payment to be made through a certain target account when the target virtual resource is purchased. The server may further obtain resource information of the target virtual resource from the local data based on the resource identifier of the target virtual resource, determine whether the transaction state of the target virtual resource is a state to be assigned, determine whether an ownership user of the target virtual resource is a user to which the source belongs, and determine whether the transfer interest rate corresponding to the target virtual resource is correct.
If the assigned qualification of the user to be assigned and the target virtual resource pass the verification, then it may be determined that the ownership assigned request passes the preliminary verification, and the server may continue to execute step 803 described below; if any one of the assigned qualification of the to-be-assigned user and the target virtual resource fails to verify, the ownership assigned request fails to initially verify, the server does not need to perform step 803 described below, and the server may feed back information of transaction failure to the to-be-assigned user.
It should be noted that the foregoing description of the verification method of the ownership assigned request is merely an exemplary illustration, and the embodiment of the present application is not limited to what kind of verification method is specifically adopted.
803. In response to the preliminary verification passing of the ownership grant request of the target virtual resource, the server sends the ownership grant request of the target virtual resource to a node device in the blockchain system.
In the embodiment of the present application, after determining that the ownership assigned request of the target virtual resource passes the preliminary verification, the server may broadcast the ownership assigned request to each node device of the blockchain system, and each node device verifies whether the ownership assigned request is valid again based on the data in the blockchain, that is, performs step 804 described below.
In the embodiment of the application, the ownership assigned request is initially verified based on the information stored in the local database of the server, and after the server passes the verification, the ownership assigned request is sent to the blockchain system and verified again by the blockchain system. The server performs preliminary screening on the ownership assigned request, so that the data processing capacity of the block chain system can be reduced, and invalid operation of the block chain is avoided. Of course, the server may also directly send the received ownership assigned request to the blockchain system, which is not limited in this embodiment of the present application.
804. The node equipment acquires user information of the user to be assigned and resource information of the target virtual resource from a block chain of the block chain system, and verifies assigned qualification of the user to be assigned and the target virtual resource based on the user information and the resource information.
Taking a node device to verify the ownership-allowed request as an example, in one possible implementation manner, the ownership-allowed request may carry a contract identifier of a target intelligent contract, the node device may invoke the target intelligent contract based on the contract identifier, acquire user information of the user to be allowed and resource information of the target virtual resource based on the target intelligent contract, and execute subsequent steps of verifying the allowed qualification and the target virtual resource based on the acquired information. In the embodiment of the application, the node equipment can verify the assigned qualification of the assigned user based on the user information of the to-be-assigned user and the virtual currency corresponding to the target virtual resource. For example, the node device may obtain the number of virtual currencies in the target account from the user information of the to-be-assigned user, and if the number of virtual currencies in the target account is greater than or equal to the number of virtual currencies corresponding to the target virtual resource, may determine that the to-be-assigned user has assigned qualification for the target virtual resource. The node device may also verify the target virtual resource based on ownership information and transaction status information in the resource information. In response to the to-be-assigned user having assigned qualification and the ownership information and transaction status information of the target virtual resource being correct, the ownership assigned request may be determined to be valid. The authentication process is the same as the authentication process of the server for the ownership assigned request in step 802, and will not be described in detail herein.
In one possible implementation, the node device may also verify a digital signature carried by the ownership-assigned request. For example, the second terminal and the server may each be registered in the blockchain system, and public and private keys are assigned to the first terminal and the server by the blockchain system. When the second terminal and the server send the ownership assigned request, a private key signature of the second terminal and the server can be added into the ownership assigned request, a receiver of the ownership assigned request applies a corresponding public key to match with the private key signature, and whether the ownership assigned request is valid or not is determined based on a matching result. The above-mentioned process of verifying the ownership assigned request based on the key pair is the same as the above-mentioned process of verifying the ownership assigned request based on the key pair in step 304, and will not be described in detail here.
It should be noted that the foregoing description of the method for verifying the ownership-assigned request by the node device is merely an exemplary illustration, and the embodiment of the present application is not limited to what verification method is specifically adopted.
In one possible implementation, the node device may also calculate a match score for the to-be-assigned user with the target virtual resource through a target model, and the to-be-assigned user may determine whether to proceed with trading the target virtual resource, i.e., whether to perform a subsequent virtual money transfer step, based on the match score. The target model may be a model constructed based on a deep neural network, and the specific structure of the target model is not limited in the embodiment of the present application. In the embodiment of the application, the node device can input the user information of the to-be-assigned user and the resource information of the target virtual resource into a target model, the target model can perform data analysis based on the user information of the to-be-assigned user and the resource information of the target virtual resource, extract the user characteristics of the to-be-assigned user and the resource characteristics of the target virtual resource, and further determine the matching score between the user information of the to-be-assigned user and the resource information based on the user characteristics and the resource characteristics. For example, the target model may determine the investment preference type of the to-be-assigned user based on the user information, determine the rate of return, holding time length, and other characteristics of the target virtual resource based on the resource information, and obtain the matching score according to the matching degree between the target virtual resource and the investment preference type of the to-be-assigned user, where the higher the matching between the target virtual resource and the investment preference type of the to-be-assigned user is, the higher the matching score is. The foregoing description of the method for calculating the matching score is merely an exemplary illustration, and the embodiment of the present application is not limited thereto.
The node device may send the match score to the to-be-assigned user, which determines whether to perform the virtual money transfer based on the match score. If the to-be-assigned user determines to terminate the transaction, the node device need not perform step 805 described below, and if the to-be-assigned user determines to continue the transaction, the node device may continue to perform step 805 described below. In the embodiment of the application, the risk in the virtual resource transaction process can be reduced by feeding back the matching score to the user to be assigned, so that the user is prevented from purchasing the virtual resource which does not accord with the self investment preference, and the transaction risk is reduced.
If the ownership-assigned request is authenticated and the to-be-assigned user determines to continue the transaction, the node device may continue to perform step 805 as described below; if the ownership-assigned request fails or the pending-assigned user terminates the transaction, the node device may feed back to the server information of the transaction failure without performing step 805 described below.
It should be noted that, in the steps 802, 803 and 804, in response to the target intelligent contract indicated by the contract identifier, based on the user identifier of the user to be assigned and the resource identifier of the target virtual resource, the user information of the user to be assigned and the resource information of the target virtual resource are obtained from the blockchain of the blockchain system; and verifying the assigned qualification of the user to be assigned and the target virtual resource based on the user information and the resource information. In the embodiment of the application, the data stored in the blockchain is undeletable and untampereable, so that the node equipment can acquire the comprehensiveness and accuracy of the user information and the resource information when carrying out ownership assigned request verification, the accuracy of a verification result can be further ensured, the validity of the ownership assigned request is ensured, and the illegal transaction is avoided.
805. The node device initiates a virtual money transfer request in the blockchain system in response to the assigned qualification of the to-be-assigned user and the target virtual resource verification passing.
The virtual currency transfer request may be used to transfer virtual currency corresponding to the target virtual resource from the account of the user to be assigned to the account of the user to whom the target virtual resource belongs.
In one possible implementation, in response to the assigned qualification of the to-be-assigned user and the verification of the target virtual resource passing, the node device may invoke a target intelligent contract in the blockchain system, and the target intelligent contract sets the transaction state of the target virtual resource to a pre-transaction state, that is, locks the target virtual resource, so as to avoid transaction conflicts caused by other users initiating transactions on the target virtual resource. Of course, the locking time may also be set to the target virtual resource, for example, the locking time may be set to 5 seconds, that is, the transaction state of the target virtual resource is 5 seconds with the duration of the transaction state, and if the blockchain system does not complete the subsequent virtual money transfer step within 5 seconds, it may be determined that the transaction fails, and the transaction state of the target virtual resource is restored to the state to be assigned.
In one possible implementation, after the target virtual resource is locked, the virtual money transfer request may be initiated in the blockchain system by the target smart contract, and the step of transferring the virtual money corresponding to the target virtual resource from the account of the user to be assigned to the account of the user to whom the source belongs is performed. For example, the node device may send a request for a virtual money transfer to the server based on the target smart contract, and in response to the request, the server may perform a step of virtual money transfer based on the target smart contract, that is, deducting the virtual money corresponding to the target virtual resource from the target account of the to-be-assigned user, and transferring the virtual money to the account of the original user. In the embodiment of the application, the virtual money transfer is completed based on the intelligent contract in the blockchain system, so that the transaction security can be improved. In one possible implementation, in response to completion of the virtual money transfer step execution, the node device may set the transaction status of the target virtual resource to a transaction completion status via a target smart contract, deleting transfer information of the target virtual resource from a transaction list of a target transaction platform in the blockchain system. The server may update the display information of the transaction display page and the data in the local database based on the data in the blockchain system, and the second terminal may no longer display the transfer information of the target virtual resource.
In one possible implementation, after the virtual money transfer is completed, that is, after the target virtual resource transaction is completed, the server may send a prompt for the completion of the transaction to the one terminal and the second terminal, so as to inform the user to whom the source belongs and the user to be assigned that the ownership transfer of the target virtual resource is completed.
806. The node device stores an ownership transfer record of the target virtual resource on the blockchain in response to the virtual money transfer request.
The ownership transfer record is used for recording that ownership of the target virtual resource is updated from the original affiliated user to the to-be-assigned user.
In one possible implementation, the ownership transfer record may be added to a memory pool of a node device in the blockchain system, the node device may construct a block based on the ownership transfer record, i.e., the node device may package data in the memory pool according to a target period to construct a block, and then store the block containing the ownership transfer record into the blockchain based on a consensus mechanism. It should be noted that the specific method for storing the ownership transfer record in the blockchain is not limited in the embodiment of the present application.
Any combination of the above optional solutions may be adopted to form an optional embodiment of the present application, which is not described herein.
According to the technical scheme provided by the embodiment of the application, the user information of the user to be assigned and the resource information of the target virtual resource are acquired from the blockchain of the blockchain system in response to the ownership assigned request of the target virtual resource, and the accuracy of acquiring the user information and the resource information can be ensured because the data stored in the blockchain is undeletable and untampered, so that the assigned qualification of the user to be assigned and the target virtual resource are verified based on the user information and the resource information, the feasibility and the legality of the assignment can be determined, virtual currency transfer is performed in the blockchain system in response to the assigned qualification of the user to be assigned and the verification of the target virtual resource, ownership assignment records of the target virtual resource are stored on the blockchain, the ownership of the target virtual resource is updated from the original user to be assigned, and the security of the target virtual resource can be improved based on the blockchain to execute the assignment step. Fig. 10 is a schematic diagram of data interaction in a resource processing process according to an embodiment of the present application, referring to fig. 10, in the resource processing process, a user may send a request to a server 1002 of a target application platform through a client 1001 of the target transaction platform, where the request may be an ownership assigned request, an ownership transfer request, etc., and the server 1002 performs data confirmation to a blockchain system 1003, and the blockchain system 1003 may feed back a data confirmation result to the server 1002, and then the server 1002 feeds back data to the client 1001, that is, feeds back data to the user. In the resource processing process, namely, transaction data generated in the transaction process is verified by the blockchain system, so that the transaction safety can be ensured.
Fig. 11 is a schematic structural diagram of a resource processing device according to an embodiment of the present application, referring to fig. 11, the device includes:
a receiving module 1101, configured to receive an ownership assigned request, where the ownership assigned request carries a user identifier of a user to be assigned, a resource identifier of a target virtual resource to be assigned by the request, and an intelligent contract identifier;
an obtaining module 1102, configured to obtain, in response to the target intelligent contract indicated by the contract identifier, user information of the user to be assigned and resource information of the target virtual resource from a blockchain of the blockchain system based on a user identifier of the user to be assigned and a resource identifier of the target virtual resource;
