[0048] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0050] It should be noted that the acquisition, storage, use and processing of data in the embodiments of the present application are in compliance with the relevant provisions of national laws and regulations.

[0051] It should be noted that in the embodiments of the present application, certain software, components, models and other existing solutions in the industry may be mentioned, and they should be regarded as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of the present application, but it does not mean that the applicant has or will necessarily use the solution.

[0052] With the continuous improvement of economic level, the types and number of transactions involved in various industries have increased dramatically. Usually, the transaction data involved in various industries will be stored in the database, which is convenient for users to query historical transaction data. Moreover, for the databases corresponding to the two parties of the transaction, the transaction data of the same transaction will be checked for consistency to ensure the consistency of the transaction and the security of resource information.

[0053] At present, both the transaction request device and the transaction response device will first submit the transaction data to the database, and then determine the consistency of the transaction by verifying whether the transaction data corresponding to the same transaction is consistent between multiple databases. This verification method is inefficient and the verification is not timely, resulting in low security of resource information.

[0054] It should be noted that transaction consistency refers to the transaction consistency of the upstream and downstream of the transaction. Transaction consistency must be ensured for a transaction submission. For example, for a transaction, the transaction data of the transaction request device and the transaction response device must be consistent.

[0055] In order to solve the problems of the prior art, the embodiments of the present application provide a data verification method, device, equipment, medium and product. The data verification method provided by the embodiments of the present application is applied to a financial business system, and the financial business system includes multiple blockchain nodes, and the multiple blockchain nodes include a first target blockchain node and a second target blockchain node. Based on the different nodes in the blockchain built by the two parties to the transaction, first query whether the blockchain node records the transaction data corresponding to the target transaction identifier sent by the transaction response device, that is, whether there is transaction data corresponding to the transaction with the same transaction identifier. If so, send the first target information to the transaction response device for the transaction response device to perform subsequent transaction processes; receive the transaction data sent by the transaction response device, record it using different blockchain nodes, and then verify whether the transaction data recorded by the two blockchain nodes are consistent. If they are consistent, it means that the transactions are consistent, write the data in the two blockchain nodes into the database, and verify the transaction data corresponding to the same transaction in time, thereby improving the security of resource information.

[0056] The following first introduces the data verification method provided in the embodiment of the present application. Figure 1 As shown, the data verification method provided in the embodiment of the present application includes the following steps.

[0057] S110: Receive a query request sent by a transaction response device, where the query request includes a target transaction identifier.

[0058] Here, the target transaction identifier is the transaction identifier carried by the transaction request device when sending a transaction request to the transaction response device.

[0059] In some embodiments, before the financial service system receives the query request sent by the transaction response device, the transaction request device sends a transaction request to the transaction response device, and the transaction request includes basic transaction information and a target transaction identifier. The basic transaction information includes a transaction account number, a replacement quantity of resource information, and a type of resource information. Before the transaction response device adjusts the resource information based on the basic transaction information, it first sends a query request to the financial service system. If the transaction data corresponding to the target transaction identifier is recorded in the blockchain node, it means that the transaction request device has adjusted the resource information and generated the transaction data.

[0060] The transaction data may include, but is not limited to, the transaction account number, the exchange quantity of resource information, the type of resource information, the transaction time, etc.

[0061] It should be noted that a blockchain platform is built in the financial business system, and the blockchain platform includes multiple blockchain nodes, and the multiple blockchain nodes include a first target blockchain node and a second target blockchain node. Each blockchain node corresponds to a database node.

[0062] S120. In response to the query request, query whether multiple blockchain nodes record the first transaction data corresponding to the target transaction identifier.

[0063] Here, the first transaction data is set in advance.

[0064] In some embodiments, the first transaction data is transaction data sent by the transaction request device, and is transaction data generated after the transaction request device adjusts resource information.

[0065] It should be noted that multiple blockchain nodes can only record transaction data and do not store transaction data. Regardless of whether the transaction data can pass the consistency check, the transaction data in the blockchain node will disappear after the verification is completed.

[0066] S130. When it is found that the first target blockchain node records the first transaction data, the first target information is sent to the transaction response device, so that the transaction response device adjusts the resource information based on the first transaction data to obtain the second transaction data, and the second transaction data includes the target transaction identifier.

[0067] Here, the first target information is set in advance. The first target information indicates that the transaction corresponding to the target transaction identifier in the transaction response device can continue.

[0068] In some embodiments, the first target information includes first transaction data, and the transaction response device adjusts the resource information based on the first transaction data to obtain second transaction data.

[0069] In some embodiments, the transaction response device adjusts the resource information based on the basic information of the transaction to obtain the second transaction data. Here, the basic information of the transaction is obtained from the transaction request sent by the transaction request device.

[0070] The second transaction data may include, but is not limited to, a transaction account number, a replacement quantity of resource information, a type of resource information, a transaction time, etc.

[0071] S140: Receive second transaction data sent by the transaction response device.

[0072] S150. Use the second target blockchain node to record the second transaction data.

[0073] Here, the second target blockchain node and the first target blockchain node can be different blockchain nodes or the same blockchain node.

[0074] In some embodiments, if the second target blockchain node and the first target blockchain node are different blockchain nodes, the second target blockchain node is only used to record the second transaction data, and the first target blockchain node is only used to record the first transaction data.

[0075] In some embodiments, if the second target blockchain node and the first target blockchain node are the same blockchain node, the blockchain node is used to record the first transaction data and the second transaction data.

[0076] In some embodiments, the second target blockchain node is a blockchain node configured for the transaction response device, or a randomly selected blockchain node.

[0077] S160. When the first transaction data and the second transaction data are consistent, write the data of the first target blockchain node and the second target blockchain node into the database.

[0078] Here, after the data of the first target blockchain node and the second target blockchain node are successfully written into the database, the transaction corresponding to the target transaction identifier is completed.

[0079] In some embodiments, when the first transaction data and the second transaction data are consistent, it means that the transaction transaction corresponding to the target transaction identifier has passed the consistency check, and the data of the first target blockchain node and the second target blockchain node are blocked. When the data is successfully blocked, the database is also successfully written to achieve data consistency.

[0080] It should be noted that the consensus algorithm of blockchain is used to block data, that is, either the data succeeds together or fails together. There is no possibility of one succeeding and the other failing.

[0081] In this way, based on the different nodes in the blockchain built by the two parties to the transaction, it is first queried whether the blockchain node has recorded the transaction data corresponding to the target transaction identifier sent by the transaction response device, that is, whether there is transaction data corresponding to the transaction with the same transaction identifier. If so, the first target information is sent to the transaction response device for the transaction response device to perform subsequent transaction processes; the transaction data sent by the transaction response device is received, recorded using different blockchain nodes, and then it is verified whether the transaction data recorded by the two blockchain nodes are consistent. If they are consistent, it means that the transactions are consistent, and the data in the two blockchain nodes are written into the database, and the transaction data corresponding to the same transaction is verified in time, thereby improving the security of resource information.

[0082] Based on this, in some embodiments, such as Figure 2 As shown, the above S150 may specifically include:

[0083] S151, receiving a first login key sent by a transaction response device;

[0084] S152. When the first login key meets the preset conditions, the second transaction data is recorded using the second target blockchain node.

[0085] Here, the first login key is set in advance. The preset condition is set in advance.

[0086] In some embodiments, before the above S151, the financial service system performs identity authentication on the transaction response device, and after the identity authentication is passed, allocates and sends a first login key to the transaction response device.

[0087] In some embodiments, the above S152 may specifically include:

[0088] When the first login key is consistent with the preset login key in the financial business system and the first login key meets the usage time information, the second transaction data is recorded using the second target blockchain node.

[0089] Here, the usage time limit information may be pre-set. For example, the usage time limit information includes a first expiration time. If the time of receiving the first login key sent by the transaction response device exceeds the first expiration time, it is considered that the first login key does not meet the usage time limit information.

[0090] In some embodiments, when the first login key does not meet the preset condition, a prompt message is sent to the transaction request device to prompt the user to pay attention to the security of resource information and transaction data.

[0091] In this way, the use authority of the transaction response device is verified through the first login key. Only after the verification is passed can the second target blockchain node be used to record the second transaction data sent by the transaction response device until the transaction is completed, thereby improving the security of resource information and transaction data.

[0092] Based on this, in some embodiments, such as Figure 3 As shown, before the above S110, the method may further include:

[0093] S101, receiving first transaction data sent by a transaction request device, where the first transaction data includes a target transaction identifier;

[0094] S102. Use a first target blockchain node among multiple blockchain nodes to record first transaction data.

[0095] Here, the first transaction data is transaction data generated after the transaction request device adjusts the resource information.

[0096] In some embodiments, before the above S101, the transaction request device receives input of basic transaction information, adjusts resource information based on the basic transaction information, and generates first transaction data, where the first transaction data includes a target transaction identifier.

[0097] The first transaction data may include, but is not limited to, a transaction account number, a replacement quantity of resource information, a type of resource information, a transaction time, etc.

[0098] In some embodiments, the first target blockchain node is a blockchain node configured for the transaction requesting device, or a randomly selected blockchain node.

[0099] In this way, before receiving the query request sent by the transaction response device, the first transaction data sent by the upstream transaction request device is first received for comparison with the second transaction data sent by the downstream transaction response device to verify whether the upstream and downstream transaction affairs are consistent, thereby improving the security of resource information.

[0100] Based on this, in some embodiments, such as Figure 4 As shown, the above S102 may specifically include:

[0101] S210, receiving a second login key sent by a transaction requesting device;

[0102] S220. When the second login key meets a preset condition, the first transaction data is recorded using a first target blockchain node among multiple blockchain nodes.

[0103] Here, the second login key is set in advance. The preset condition is set in advance.

[0104] In some embodiments, before the above S210, the financial service system performs identity authentication on the transaction request device, and after the identity authentication is passed, allocates and sends a second login key to the transaction request device.

[0105] In some embodiments, the above S220 may specifically include:

[0106] When the second login key is consistent with the preset login key in the financial business system and the second login key meets the usage time information, the first target blockchain node is used to record the first transaction data.

[0107] Here, the usage time limit information may be pre-set. For example, the usage time limit information includes a second expiration time. If the time of receiving the second login key sent by the transaction request device exceeds the second expiration time, it is considered that the second login key does not meet the usage time limit information.

[0108] In some embodiments, when the second login key does not meet the preset condition, a prompt message is sent to the transaction request device to prompt the user to pay attention to the security of resource information and transaction data.

[0109] In this way, the use authority of the transaction request device is verified through the second login key. Only after the verification is passed can the first target blockchain node be used to record the first transaction data sent by the transaction request device until the transaction is completed, thereby improving the security of resource information and transaction data.

[0110] Based on this, in some embodiments, such as Figure 5 As shown, after the above S160, the method may further include:

[0111] S170. Send second target information to the transaction requesting device.

[0112] Here, the second target information is set in advance. The second target information represents the end of the transaction.

[0113] As an example, the second target information is "Transaction Completed".

[0114] In this way, by sending the second target information to the transaction request device, the user is notified that the transaction corresponding to the target transaction identifier has been completed, and the user does not need to perform complex query work, thereby improving the user experience.

[0115] Based on this, in some embodiments, such as Figure 6 As shown, corresponding to the above S160, the method may further include:

[0116] S180: When the first transaction data and the second transaction data are inconsistent, send third target information to the transaction request device.

[0117] Here, the third target information is set in advance. The third target information indicates that the transaction has not passed the consistency check.

[0118] As an example, the third target information is "the transaction contents are inconsistent".

[0119] In this way, by sending the third target information to the transaction request device, the user is notified that the transaction corresponding to the target transaction identifier has not passed the consistency check, and the user is reminded to pay attention to the security of the resource information, thereby improving the security of the resource information.

[0120] In the embodiments provided in this application, blockchain is used to achieve transaction consistency, avoiding complex code development to ensure transaction consistency of the database. The blockchain consensus mechanism is used to ensure transaction consistency, reducing a large amount of coding to achieve transaction consistency.

[0121] In the embodiment provided in this application, through the blockchain platform, when the transaction data recorded by the blockchain nodes reach a consensus and are placed in a block, the database transaction is submitted and the transaction data is submitted to the corresponding database, which improves the security of resource information. And based on the record-only nature of the blockchain, the security of transaction data can be further improved.
