Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
In order to facilitate understanding of the technical processes of the embodiments of the present application, some terms referred to in the embodiments of the present application are explained below:
block chain (Block chain): the method 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. The blockchain is essentially a decentralized database, which is a string of data blocks associated by cryptography, each data block containing information about a network transaction for verifying the validity (anti-counterfeiting) of the information and generating the next block, each block containing a timestamp and a link to the previous block. In a narrow sense, a blockchain is a distributed ledger of data blocks assembled in a sequential manner into a chain data structure in chronological order and cryptographically secured as non-falsifiable and non-forgeable, i.e. the data in the blockchain will be irreversible once recorded.
Consensus mechanism (Consensus mechanism): the block chain system is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes. In the block chain system, the verification and confirmation of the transaction can be completed in a short time through the voting of special nodes, and if a plurality of nodes with irrelevant benefits can achieve consensus on a transaction, all the nodes in the system can also achieve consensus on the transaction.
Smart contract (Smart contract): is a computer protocol intended to propagate, validate or execute contracts in an informational manner. Each node in the blockchain system can automatically execute a contract program according to a specific condition, can operate data stored in the chain, and is an important way for a user to interact with the blockchain and realize business logic by using the blockchain. The goal of smart contracts is to provide a secure method over traditional contracts and to reduce other transaction costs associated with the contracts, which allows for trusted transactions that are traceable and irreversible without third parties.
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 a public part of the key pair, and the private key being a non-public part. The public key is typically used to encrypt session keys, verify digital signatures, or encrypt data that can be decrypted with a corresponding private key. The pair of keys derived by such an algorithm can be guaranteed to be unique. When such a key pair is used, if one of the keys is used to encrypt a piece of data, the other key must be used to decrypt the encrypted piece of data. For example, encrypting data with a public key necessitates decryption with the private key, and if encrypting with the private key, also must decrypt with the 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 disclosure, 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, and the like. 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 trading platform, and the target trading platform may support trading of virtual resources, and the virtual resources may be financial products and the like. For example, the client of the target trading platform running in the terminal 100 may log in an account of any user, and any user may transfer or purchase a virtual resource such as a financial product through the target trading platform. The terminal 100 may be generally referred to as one of a plurality of terminals, and the present embodiment is illustrated only by the terminal 100.
The server 110 may be a background server of the target trading platform, and the server 110 may be used for processing trading data generated in the 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 basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a Network service, cloud communication, a middleware service, a domain name service, a security service, a CDN (Content Delivery Network), a big data and artificial intelligence platform.
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 a server, a host, a user terminal, etc. The node devices 1201 and the node devices 1201 can share data, that is, each node device 1201 can jointly maintain a blockchain in the blockchain system 120. Among them, 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 (TCP) Protocol. Each node device 1201 may receive input information during normal operation, and maintain shared data in the blockchain system 120 based on the received input information, i.e., maintain a blockchain in the blockchain system 120. In order to ensure information intercommunication in the blockchain system 120, an information connection may exist between each node device 1201 in the blockchain system 120, and the node devices 1201 may perform information transmission 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 shared data, so that the data stored on all node devices in the blockchain system are consistent. In this embodiment, the node device 1201 may obtain the transaction data sent by the server 120, process the transaction data, and record the transaction process of the virtual resource.
In the embodiment of the present application, both the terminal 100 and the server 110 can be registered as node devices in the blockchain system 120. The terminal 100, the server 110 and the blockchain system 120 may be directly or indirectly connected through wired or wireless communication to realize data transmission.
Those skilled in the art will appreciate that the number of terminals, servers, and node devices may be greater or fewer. The number and the device type of the terminal, the server and the node device are not limited in the embodiment of the application.
According to the technical scheme, the target virtual resources with certain values can flow among users in an ownership transfer mode, and the users holding the target virtual resources at 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, the user needs to hold the target virtual resource within a fixed holding period to obtain a higher benefit, and if an asset invested in the target virtual resource is paid in advance, the obtained benefit 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 ownership is continuously held by the ownership transfered user. That is, the target virtual resource is held by the user for the fixed holding period, and the assets put into the target virtual resource do not need to be withdrawn. In this case, the user holding the target virtual resource in different time periods can obtain a high profit and improve the liquidity of the target virtual resource.
Fig. 2 is a flowchart of a resource processing method according to an embodiment of the present application, and as shown in fig. 2, the method may be applied to a node device of a blockchain system, and the method specifically includes the following steps:
201. and receiving an ownership transfer request, wherein the ownership transfer request carries the user identification of the user to be transferred, the resource identification of the requested target virtual resource to be transferred and the intelligent contract identification.
The target virtual resource can be any type of financial product, for example, a periodic financial product, and the target virtual resource can be traded in the target trading platform. The to-be-granted user is a user who will acquire ownership of the target virtual resource, that is, the sending user of the ownership granted request.
The target virtual resource can be transferred by the original user, that is, by the user who currently owns the target virtual resource, and the original user can transmit an ownership transfer request for the target virtual resource to the node device in the blockchain system through the client of the target trading platform to transfer the ownership of the target virtual resource. And the node equipment responds to the ownership transfer request, and releases the transfer information of the target virtual resource in the blockchain system, and other users of the target trading platform can acquire the transfer information released in the blockchain system.
After the user to be granted obtains the transfer information of the target virtual resource through the client of the target trading platform, that is, after it is determined that the ownership of the target virtual resource needs to be transferred, an ownership granting request may be sent to the node device to obtain the ownership of the target virtual resource.
202. And responding to a target intelligent contract indicated by the contract identification, and acquiring user information of the user to be assigned and resource information of the target virtual resource from a block chain of a block chain system based on the user identification of the user to be assigned and the resource identification of the target virtual resource.
The target intelligent contract may be used to indicate data processing logic in the ownership transaction process of the target virtual resource, and may include processing logic for ownership transfer requests and processing logic for ownership transfer requests.
In this embodiment, the blockchain of the blockchain system may store user information of each user of the target trading platform and resource information of each virtual resource. After receiving the ownership granting request, the node device may invoke a target intelligent contract indicated by the contract identifier, and obtain information and resource information from the block chain 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. Due to the fact that the data stored in the block chain cannot be tampered and deleted, accuracy and comprehensiveness of the user information and the resource information can be guaranteed, and the influence on the follow-up user verification process to be given and the target virtual resource verification process due to inaccurate data is avoided.
203. 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 to obtain a verification result.
The granted qualification refers to that the user to be granted needs to satisfy the granted condition of the target virtual resource, for example, when the number of virtual currencies included in the account of the user to be granted is greater than or equal to the number of virtual currencies corresponding to the target virtual resource, the user to be granted has the granted qualification of the target virtual resource, that is, sufficient assets need to be present in the account of the user to be granted to purchase the target virtual resource. Of course, it may also be determined whether the user to be granted has the granted qualification based on other information, for example, whether the user information of the user to be granted includes a bad transaction record, and the like, which is not limited in this embodiment of the application.
In this embodiment of the present application, verifying the target virtual resource may include verifying the validity of the target virtual resource, that is, verifying whether an ownership user of the target virtual resource is the original owner user; may include verifying the transactional state of the target virtual resource, i.e., verifying whether the target virtual resource is tradable. Of course, the virtual resource may also be verified from other aspects, which is not limited in this embodiment of the present application.
In the above technical solution, the user qualification and the target virtual resource of the user to be granted are verified, so that the ownership granting request can be ensured to be valid, 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 this embodiment, if the granted qualification of the user to be granted and the verification of the target virtual resource pass, the virtual money transfer may be performed in the blockchain system, and the virtual money corresponding to the target virtual resource is transferred from the account of the user to be granted to the account of the original user of the target virtual resource. That is, the user to be granted pays a certain amount of virtual money to the original user of the target virtual resource to purchase the target virtual resource and obtain ownership of the target virtual resource. The number of virtual currencies corresponding to the target virtual resource may be set by the original user of the target virtual resource. In one possible implementation, the node device may further store an ownership transfer record in the blockchain, and specifically, the node device may package the ownership transfer record and other transaction information into a chunk, perform consensus on the chunk by each node device in the blockchain system, and add the chunk to the tail of the blockchain in response to the chunk passing the 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-granted user, and 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-granted user, and a number of virtual currencies corresponding to the target virtual resource and a timestamp.
In this embodiment of the application, if any one of the assigned qualification of the user to be assigned and the target virtual resource fails to be verified, transfer rejection information may be output, and the blockchain system may feed back a result of the transaction failure to the user to be assigned.
The above-mentioned embodiment is only a brief introduction to an embodiment of the present application, and the technical solution provided in the embodiment of the present application can ensure the accuracy of obtaining the user information and the resource information by obtaining the user information of the user to be granted and the resource information of the target virtual resource from the blockchain of the blockchain system in response to the ownership grant request for the target virtual resource, since the data stored in the blockchain cannot be deleted or tampered, so that the availability and the validity of the transfer can be determined by verifying the grant of the user to be granted and the target virtual resource based on the user information and the resource information, performing virtual money transfer in the blockchain system in response to the grant of the user to be granted and the verification of the target virtual resource, storing the transfer record of the target virtual resource on the blockchain, and updating the ownership of the target virtual resource from the original user to the user to be granted so as to realize the transfer of the target virtual resource, and executing the transfer step based on the block chain, so that the safety of the transfer process of the target virtual resource can be improved.
The above embodiment describes a process of acquiring ownership of a target virtual resource by a user to be granted, where the target virtual resource may be a virtual resource transferred by an original user to which the target virtual resource belongs, and the process of transferring ownership of the target virtual resource by the original user is shown in fig. 3. Fig. 3 is a flowchart of a resource transfer method provided in 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:

The server may be a background server of the target trading platform, and the server may process data generated by a client of the target trading platform. In the embodiment of the present application, the virtual resource may be a financial product issued by a financial institution such as a bank.
In this embodiment of the present application, the ownership transfer request may carry the user identifier of the original user, the 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 as a certificate number, an account address, and the like, which is not limited in this embodiment of the application. The resource identifier 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 number of virtual currencies 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 original user, and the number of virtual currencies corresponding to the target virtual resource, that is, the number of virtual currencies paid by the target virtual resource purchased by the transferee, 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 further include information such as remaining holding time of the target virtual resource, which is not limited in the embodiment of the present application.
In a possible implementation manner, the first terminal may display a detail page of the target virtual resource, referring to fig. 4, where fig. 4 is a schematic diagram of a detail page provided by an embodiment of the present application, and the detail page may include an information display area 401 of the target virtual resource and an assignment control 402. Taking the target virtual resource as a periodic financing 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 financing product. When the first terminal detects that the original user triggers the assignment control 402, the first terminal may display an assignment page of the target virtual resource, where the assignment page is used to collect assignment information of the target virtual resource.
Referring to fig. 5, fig. 5 is a schematic diagram of an assignment page provided by an embodiment of the present application, and the assignment page may include an assignment share display area 501, an assignment 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 original user, that is, all shares held by the original user need to be transferred in the current virtual resource transfer process. Of course, the originally affiliated user may also set the transfer share, and only transfer a part of shares in one virtual resource transfer process, which is not limited in this application embodiment. In this embodiment of the application, the original 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 number of virtual currencies corresponding to the target virtual resource in the resource transfer process based on the transfer interest rate and the transfer share set by the original user. In a possible implementation manner, for a virtual resource, multiple interest rate intervals may be set based on the remaining holding duration of the virtual resource, that is, different remaining holding durations correspond to different interest rate intervals, for example, when the remaining holding duration of the target virtual resource is less than or equal to 2 years, the transfer interest rate may be set in a first interest rate interval, and when the remaining holding duration of the target virtual resource is greater than 2 years, the transfer interest rate may be set in the first interest rate interval. In a possible implementation manner, the higher the transfer interest rate set by the original user is, the higher the profit obtained after the target virtual resource is purchased by the transferee user is, the larger the number of virtual currencies corresponding to the target virtual resource determined based on the transfer share of the transfer interest rate is, that is, the larger the number of virtual currencies paid by the transferee user for purchasing the target virtual resource is. It should be noted that the above description of the relationship between the number of virtual currencies corresponding to the target virtual resource and the transfer interest rate and transfer share is only an exemplary description, and the embodiment of the present application does not limit which calculation method is specifically adopted to determine the number of virtual currencies corresponding to the target virtual resource. When the first terminal detects that the original user triggers the confirmation control 504, the first terminal may obtain information, such as transfer share, transfer interest rate, and number of virtual currencies corresponding to the target virtual resource, collected by the transfer page, as transfer information of the target virtual resource, and generate an ownership transfer request of the target virtual resource based on the transfer information.
The first terminal can send the ownership transfer request of the target virtual resource to a background server of the target trading platform, and the server performs data processing based on the ownership transfer request.
302. And the server responds to the ownership transfer request of the target virtual resource and verifies the target virtual resource and the transfer information of the target virtual resource.
In one possible implementation, the server may perform preliminary verification on the target virtual resource and the transfer information of the target virtual resource based on data stored in the local database. The local database may store user information of each user and resource information of each virtual resource in the target trading platform. For example, the server may obtain the user information of the original user from the local data based on the user identifier of the original user, and verify whether the virtual resource held by the original user 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 identifier of the target virtual resource, resource information of the target virtual resource is acquired from a local database, the resource information may include information such as a interest rate interval and a transaction state corresponding to the target virtual resource, and the server may compare the assignment information of the target virtual resource with the resource information, verify whether the interest rate of the assignment of the target virtual resource is within the interest rate interval, and verify whether the target virtual resource is in a tradable state. It should be noted that the above description of the verification method for the target virtual resource and the assignment information is only an exemplary description, and the embodiment of the present application does not limit which verification method is specifically adopted.
If the target virtual resource and the transfer information of the target virtual resource are 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 information of the transaction failure to the original user.
303. And in response to the verification of the target virtual resource and the transfer information of the target virtual resource, the server sends an ownership transfer request of the target virtual resource to the node equipment in the blockchain system.
In this embodiment, after determining that the transfer information of the target virtual resource and the target virtual resource passes 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 data in the blockchain, that is, step 304 is executed.
In the embodiment of the application, the target virtual resource and the transfer information are preliminarily verified based on the information stored in the local database of the server, that is, whether the ownership transfer transaction of the target virtual resource is legal or not is preliminarily verified, and after the server passes the verification, the ownership transfer request is sent to the block chain system, and the block chain system conducts verification again. The ownership transfer transaction is primarily screened by the server, so that the data processing amount of the blockchain system can be reduced, and invalid operation of the blockchain 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 invention.
304. The node equipment acquires user information of an original user and resource information of a target virtual resource from the block chain, 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 an example that one node device verifies the ownership transfer request, in one possible implementation manner, the ownership transfer 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, obtain, based on the target intelligent contract, user information of the original user and resource information of the target virtual resource, and perform a subsequent verification step of the ownership transfer request based on the obtained information. In this embodiment of the present application, the node device may verify whether the ownership of the target virtual resource by the original belonging user is valid based on the user information of the original belonging user and the resource information of the target virtual resource; verifying whether the transfer information of the target virtual resource is effective or not based on the resource information of the target virtual resource; and verifying whether the target virtual resource is in a tradable state or not based on the transaction state information in the resource information of the target virtual resource. In response to that the ownership of the target virtual resource is valid by the original user, the transfer information of the target virtual resource is valid, and the target virtual resource is in a tradable state, it may be determined that the ownership transfer request is valid. The verification process is the same as the verification process of the target virtual resource and the transfer information in step 302, and is not described herein again.
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 both register in the blockchain system, and the public key and the private key are assigned to the first terminal and the server by the blockchain system. The first terminal may add its private key signature to the ownership transfer request when sending the ownership transfer request to the server, and after receiving the ownership transfer request, the server may apply the public key of the first terminal to match the private key signature, and if matching is successful, may determine that the ownership transfer request is valid; similarly, when the server sends the ownership transfer request to the node device, the server may add its private key signature to the ownership transfer request, and after the node device receives the ownership transfer request, the node device may verify the ownership transfer request by using the public key of the server.
It should be noted that the above description of the method for node device to authenticate the target virtual resource and transfer information is only an exemplary description, and the embodiment of the present application does not limit which authentication method is specifically adopted. If the ownership transfer request is verified, the server may proceed to step 305; if the ownership transfer request fails to be verified, the server does not need to perform step 305, and the server may feed back information of the transaction failure to the original belonging user.
It should be noted that, in the above step 302, step 303, and step 404, in response to the target intelligent contract indicated by the contract identifier, based on the user identifier of the original user and the resource identifier of the target virtual resource, the user information of the original user and the resource information of the target virtual resource are obtained from the block chain; and verifying the validity of the ownership transfer request based on the user information of the original user, the resource information of the target virtual resource and the transfer information of the target virtual resource. In the embodiment of the application, because the data stored in the blockchain cannot be deleted and tampered, the comprehensiveness and accuracy of the node device for acquiring the user information and the resource information can be ensured, the accuracy of the verification result can be further ensured, the ownership transfer request is ensured to be effective, and the condition of illegal transaction is avoided.
305. And responding to the verification of the ownership transfer request, and the node equipment issues transfer information of the target virtual resource in the blockchain system.
In one possible implementation manner, after determining that the ownership transfer request passes the verification, 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 a waited state. After the server finishes modifying the resource information of the target virtual resource, the server may send a publishing request for the target virtual resource to the blockchain system, and the node device in the blockchain system executes the step of publishing the target virtual resource.
In a possible implementation manner, the node device may add the assignment information of the target virtual resource to a transaction list of a target transaction platform in the blockchain system, and in this 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 assignment information of each virtual resource to be granted in each transaction platform. In this embodiment, the node device further 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 status update record, where the transaction status update record may include information that the target virtual resource is in a to-be-granted state; then, storing the transaction state updating record into a memory pool, and packing data in the memory pool based on a target period to construct a block; finally, based on the consensus mechanism, the newly constructed block is added to the tail of the block chain to complete the update of the transaction state. The memory pool may be used to store data not linked in the blockchain system, and the target period may be set by a developer, which is not limited in the embodiment of the present application. In one possible implementation, the updating process of the transaction state may be completed based on a target intelligent contract, that is, in response to the verification of the ownership transfer request, the node device may invoke the target intelligent contract in the blockchain system, and the target intelligent contract sets the transaction state of the target virtual resource to the to-be-yielded state.
The above description of the assignment information distribution method for the target virtual resource is merely an exemplary description, and the embodiment of the present application does not limit which assignment information distribution method is specifically adopted.
In the embodiment of the application, the transaction state information of the target virtual resource is modified in the blockchain system, and the blockchain system records the transfer information of the target virtual resource, so that the transfer information can be prevented from being tampered, and the ownership transfer transaction is guaranteed to be real and effective.
306. And the node equipment sends the target virtual resource release result to the server.
In this embodiment, after the blockchain system completes the publishing of the target virtual resource, the publishing result of the target virtual resource may be fed back to the server.
In response to that the target virtual resource is successfully published 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 bulletin page of the target transaction platform based on the transaction list, add assignment information of the target virtual resource to the transaction bulletin page, and the first terminal may display the assignment information of the target virtual resource in the transaction bulletin page in a link or hyperlink manner. Referring to fig. 6, fig. 6 is a schematic diagram of a transaction bulletin page provided in the embodiment of the present application. The page may display transfer information 601 of the target virtual resource transferred by the original user, or may display transfer information of virtual resources transferred by other users. In a 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 message may further include a link of a page which is successfully published, and the first terminal may display the page which is successfully published when detecting a click operation of the original user on the link. Fig. 7 is a schematic diagram of a successful issue page provided in an embodiment of the present application, where the successful issue page may include an information display area 701, and the information display area 701 may display the transfer share, the transfer interest rate, the number of virtual currencies corresponding to the target virtual resource, and the effective time of the transfer transaction. For example, the effective time of the transfer transaction may be set to seven days, if the target virtual resource is not transferred 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 transfer information of the target virtual resource is no longer displayed on the transaction bulletin page, and the originally affiliated user may initiate an ownership transfer request to the target virtual resource again.
In response to that the target virtual resource fails to be published in the blockchain system, the server may send a prompt message indicating that the target virtual resource fails to be published to the first terminal, and the first terminal displays the prompt message indicating that the target virtual resource fails to be published, so as to prompt the original user to resubmit the publishing 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 income is obtained in advance. For example, when the target virtual resource is a periodic financing product, a user can transfer the periodic financing product in a holding period, different users can hold the periodic financing product in different time periods, and the liquidity of the periodic financing product is improved under the condition of obtaining and guaranteeing benefits.
In the embodiment 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 assignment method provided in an embodiment of the present application, where the method may be applied in an 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-granted user of the target virtual resource, and the to-be-granted user may purchase the target virtual resource through a client of a target trading platform running in the second terminal to obtain ownership of the target virtual resource. In this embodiment of the application, the ownership transference request may carry information such as a user identifier of the user to be transfered, a resource identifier of the target virtual resource requested to be transfered, and the like.
In one possible implementation manner, the second terminal may display a trading publicity page of the target trading platform, and the transfer information of the target virtual resource may be displayed on the trading publicity page in a hyperlink form. When the second terminal detects the click operation of the to-be-assigned user on the hyperlink corresponding to the transfer information of the target virtual resource, the transaction detail page of the target virtual resource can be displayed. 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, information such as a transfer share, a transfer rate, and an effective time of the current transfer transaction of the target virtual resource. When the second terminal detects the click operation of the to-be-granted user on the purchase control, the second terminal can acquire 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-granted user, and generates an ownership granting request of the target virtual resource based on the resource identifier of the target virtual resource and the user identifier of the to-be-granted user.
The second terminal can send the ownership granted request of the target virtual resource to a background server of the target trading platform, and the server performs data processing based on the ownership granted request.
802. The server responds to the ownership granted request of the target virtual resource, and performs preliminary verification on the ownership granted request.
In one possible implementation manner, after receiving the ownership granting request, the server may perform preliminary verification on the target virtual resource and the granting qualification of the user to be granted based on the data stored in the local database. For example, the server may obtain the user information of the to-be-transfered user from the local database based on the user identifier of the to-be-transfered user, further obtain the number of the virtual money included in the target account of the to-be-transfered user, and determine whether the virtual money of the to-be-transfered user is sufficient, that is, determine whether the fund for purchasing the target virtual resource by the to-be-transfered user is sufficient. For example, the publishing platform of the target virtual resource may limit payment through a certain target account when purchasing the target virtual resource, which is not limited in the embodiment of the present application. The server can also acquire resource information of the target virtual resource from local data based on the resource identifier of the target virtual resource, judge whether the transaction state of the target virtual resource is a to-be-granted state, judge whether an ownership user of the target virtual resource is the original user and judge whether the transfer interest rate corresponding to the target virtual resource is correct.
If the granted qualification of the user to be granted and the target virtual resource are both verified, it may be determined that the ownership granted request is primarily verified, and the server may continue to perform the following step 803; if any one of the granted qualification of the user to be granted and the target virtual resource fails to be verified, the ownership granted request fails to be primarily verified, the server does not need to execute the following step 803, and the server can feed back the transaction failure information to the user to be granted.
It should be noted that the above description of the verification method of the ownership granted request is only an exemplary description, and the embodiment of the present application does not limit which verification method is specifically adopted.
803. And in response to the initial verification of the ownership granted request of the target virtual resource, the server sends the ownership granted request of the target virtual resource to the node equipment in the blockchain system.
In this embodiment, after the server determines that the ownership granted request of the target virtual resource passes the preliminary verification, the server may broadcast the ownership granted request to each node device of the blockchain system, and each node device verifies whether the ownership granted request is valid again based on the data in the blockchain, that is, the following step 804 is performed.
In the embodiment of the application, the ownership granted request is preliminarily verified based on information stored in a local database of the server, and after the server passes the verification, the ownership granted request is sent to the blockchain system and is verified again by the blockchain system. The server preliminarily screens the ownership granted requests, so that the data processing amount 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 granted request to the blockchain system, which is not limited in this embodiment.
804. The node equipment acquires user information of a user to be assigned and resource information of a target virtual resource based on a block chain of a block chain system, and verifies the assigned qualification and the target virtual resource of the user to be assigned based on the user information and the resource information.
Taking an example that one node device verifies the ownership granted request, in one possible implementation manner, the ownership granted 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, obtain user information of the user to be granted and resource information of the target virtual resource based on the target intelligent contract, and perform subsequent steps of verifying the granted qualification and the target virtual resource based on the obtained information. In this embodiment, the node device may verify the granted qualification of the granted user based on the user information of the to-be-granted 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-granted 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, it may be determined that the to-be-granted user has the granted qualification of the target virtual resource. The node device can also verify the target virtual resource based on ownership information and transaction state information in the resource information. In response to the transferee user having the transferee qualification and the ownership information and transaction status information of the target virtual resource being correct, it may be determined that the ownership transferee request is valid. The verification process is the same as the verification process of the ownership granted request by the server in step 802, and details are not described herein.
In one possible implementation, the node device may also verify a digital signature carried by the ownership transference request. For example, the second terminal and the server may both register in the blockchain system, and the public key and the private key are assigned to the first terminal and the server by the blockchain system. When the second terminal and the server send the ownership granted request, the private key signature of the second terminal and the private key signature of the server can be added to the ownership granted request, a receiver of the ownership granted request applies a corresponding public key to match the private key signature, and whether the ownership granted request is valid or not is determined based on a matching result. The process of verifying the ownership transfer request based on the key pair is the same as the process of verifying the ownership transfer request based on the key pair in step 304, and is not described herein again.
It should be noted that the above description of the method for verifying the ownership granted request by the node device is only an exemplary illustration, and the embodiment of the present application does not limit which verification method is specifically adopted.
In one possible implementation, the node device may further calculate, through a target model, a matching score of the to-be-admitted user with the target virtual resource, and the to-be-admitted user may determine whether to continue to trade the target virtual resource, i.e., whether to perform a subsequent virtual money transfer step, based on the matching 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 this embodiment of the application, the node device may input the user information of the to-be-assigned user and the resource information of the target virtual resource into a target model, and the target model may 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 a 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 characteristics such as the profitability and the duration of holding of the target virtual resource based on the resource information, and obtain the matching score according to the matching degree between the investment preference type of the to-be-assigned user and the target virtual resource, 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 above description of the matching score calculation method is merely an exemplary description, and the present embodiment is not limited thereto.
The node device may send the matching score to the transferee user, the step of determining by the transferee user whether to perform a virtual money transfer based on the matching score. If the transferee user determines to terminate the transaction, the node device does not need to perform step 805 described below, and if the transferee user determines to continue the transaction, the node device may continue to perform step 805 described below. In the embodiment of the application, the matching score is fed back to the user to be given back, so that the risk in the virtual resource transaction process can be reduced, the user is prevented from purchasing the virtual resource which is not in accordance with the investment preference of the user, and the transaction risk is reduced.
If the ownership granted request is authenticated and the transferee user determines to continue the transaction, the node device may continue to step 805; if the ownership granted request fails or the to-be-granted user terminates the transaction, the node device does not need to perform the following step 805, and the node device may feed back information of the transaction failure to the server.
It should be noted that, in the above step 802, step 803, and step 804, in response to the target intelligent contract indicated by the contract identifier, based on the user identifier of the user to be admitted and the resource identifier of the target virtual resource, the user information of the user to be admitted 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, because the data stored in the blockchain cannot be deleted and tampered, the comprehensiveness and accuracy of obtaining the user information and the resource information when the node equipment verifies the ownership granted request can be ensured, the accuracy of the verification result can be further ensured, the validity of the ownership granted request can be ensured, and the condition of illegal transaction can be avoided.
805. The node device initiates a virtual money transfer request in the blockchain system in response to the granted qualification of the user to be granted and the target virtual resource verification passing.
The virtual money transfer request may be used to transfer the virtual money corresponding to the target virtual resource from the account of the user to be granted to the account of the user to which the target virtual resource belongs.
In a possible implementation manner, in response to the granted qualification of the user to be granted 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 conflict caused by initiating a transaction to the target virtual resource by other users. Of course, a locking time may also be set for the target virtual resource, for example, the locking time may be set to 5 seconds, that is, the duration of the transaction state of the target virtual resource is 5 seconds, if the blockchain system does not complete the subsequent virtual money transfer step within 5 seconds, it may be determined that the transaction is failed, and the transaction state of the target virtual resource is recovered to the to-be-granted state.
In a possible implementation manner, after the target virtual resource is locked, the virtual money transfer request may be initiated in the blockchain system through the target intelligent contract, and the step of transferring the virtual money corresponding to the target virtual resource from the account of the user to be granted to the account of the user to which the target virtual resource belongs is performed. For example, the node device may send a request for virtual money transfer to the server based on the target intelligent contract, and in response to the request, the server may perform a step of virtual money transfer based on the target intelligent contract, that is, deducting virtual money corresponding to the target virtual resource from the target account of the user to be transfered, and transferring the virtual money to the account of the original user. In the embodiment of the application, the transaction safety can be improved by completing the virtual money transfer based on the intelligent contracts in the blockchain system. In one possible implementation manner, in response to the completion of the virtual money transfer step, the node device may set the transaction state of the target virtual resource to a transaction completion state through the target smart contract, and delete the transfer information of the target virtual resource in the transaction list of the target transaction platform in the blockchain system. The server can update the display information of the transaction bulletin page and the data in the local database based on the data in the blockchain system, and the second terminal does not display the transfer information of the target virtual resource any more.
In a possible implementation manner, after the virtual money transfer is completed, that is, after the transaction of the target virtual resource is completed, the server may send a prompt message of completion of the transaction to the one terminal and the second terminal to notify the original user and the user to be granted that the ownership transfer of the target virtual resource is completed.
806. The node device stores an ownership transfer record for the target virtual resource on the blockchain in response to the virtual money transfer request.
And the ownership transfer record is used for recording that the ownership of the target virtual resource is updated from the original user to the to-be-assigned user.
In a possible implementation manner, the ownership transfer record may be added to a memory pool of a node device in the blockchain system, and the node device may construct a block based on the ownership transfer record, that is, the node device may pack data in the memory pool according to a target cycle, construct a block, and store the block including the ownership transfer record into the blockchain based on a common recognition mechanism. It should be noted that, the embodiment of the present application does not limit the specific method for storing the ownership transfer record to the block chain.
All the above optional technical solutions may be combined arbitrarily to form optional embodiments of the present application, and are not described herein again.
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 block chain of the block chain system in response to the ownership assignment request of the target virtual resource, the accuracy of the user information and the resource information can be ensured as the data stored in the block chain can not be deleted and tampered, therefore, 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 transfer can be determined, the virtual money transfer is performed in the block chain system in response to the passing of the assigned qualification of the user to be assigned and the verification of the target virtual resource, the ownership assignment record of the target virtual resource is stored on the block chain, and the ownership of the target virtual resource is updated from the original user to the user to be assigned, the transfer of the target virtual resources is realized, and the transfer steps are executed based on the block chain, so that the safety of the transfer process of the target virtual resources can be improved. 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, which may be an ownership transfer request, or the like, to a server 1002 of a target application platform through a client 1001 of a target trading platform, and perform data validation to a blockchain system 1003 by the server 1002, and the blockchain system 1003 may feed back a data validation result to the server 1002, and then feed back data to the client 1001 by the server 1002, that is, feed back to the user. In the resource processing process, namely, transaction data generated in the transaction process are verified by the blockchain system, so that the security of the transaction can be ensured.
