[0027] It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] In the following, the technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application, so that those skilled in the art can better understand the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of the present application.

[0029] It should be noted that the terms "first", "second" and the like in the description and claims of the present application and the above drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or a chronological sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not necessarily limit to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to the process, method, product or device.

[0030] It should be noted that the relevant information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for display, analyzed data, etc.) involved in the present disclosure are all information and data authorized by the user or authorized by all parties. For example, an interface is provided between the system and the relevant user or institution. Before obtaining the relevant information, the interface needs to send a request to the aforementioned user or institution, and after receiving the consent information feedback from the aforementioned user or institution, the relevant information is obtained.

[0031] The present application will be described below in conjunction with the preferred implementation steps, Figure 1 The flowchart of the transaction processing method based on the blockchain platform provided by the embodiments of the present application is shown in Figure 1 The method comprises the following steps:

[0032] In step S101, the target data information of multiple dynamic account transactions uploaded by a target object is received through a blockchain platform, wherein the target data information at least includes payee information, payee information, transaction amount and transaction currency.

[0033] In step S102, the payee information, payee information, transaction amount and transaction currency are evaluated for security and consistency through the blockchain platform, and the evaluation result is obtained.

[0034] Step S103, if the evaluation result is passed, a number is generated for each transaction by the blockchain platform, a plurality of approval numbers are obtained, and each approval number and the target data information corresponding to the approval number are stored in the blockchain platform.

[0035] Step S104, according to each approval number, each transaction is processed.

[0036] Specifically, at present, the client needs to provide paper materials to the financial institution counter to submit an application, and the business personnel verifies and approves the third party institution offline, and then the counter can process the transaction. Such processing method brings inconvenience to the client.

[0037] In the above technical background, a transaction processing method based on a blockchain platform is proposed, which realizes online management of the target client's fund transaction through the blockchain platform, and the data of the evaluation is directly chained to achieve the purpose of data tamper-proof. Each transaction approved by the blockchain platform generates an approval number, and the transaction processing is realized through the approval number, which avoids the target object from submitting various paper materials and offline approval.

[0038] The client subject to fund supervision (i.e. the target object mentioned above) enters the target data information of each transaction in the above-mentioned blockchain platform, which at least includes the information of the payer, the information of the payee, the transaction amount, the transaction currency and other data information.

[0039] The blockchain platform performs security evaluation and consistency audit on the above-mentioned target data information such as the information of the payer, the information of the payee, the transaction amount and the transaction currency. The security evaluation mainly evaluates the risk of the client's transaction, for example, whether the amount of the transaction exceeds the safety line. The consistency audit mainly checks whether the information of the payer and the payee is the same as the information in the financial institution and the third party institution. Through the security and consistency evaluation of the target data information, the evaluation result is obtained.

[0040] In the case where the evaluation result is passed, the blockchain platform generates a corresponding approval number for each transaction that passes the evaluation, and stores each approval number and the target data information corresponding to each approval number in the blockchain platform, and uses the tamper-proof and mutual trust mechanism of the blockchain platform to register and manage the target data information. The approval number generated by the blockchain platform executes the corresponding transaction.

[0041] It should be noted that the customer can query the relevant data information and the corresponding approval number of the assessment through the target platform (which can be an electronic trading platform or the like). Moreover, the customer can select a target account transaction to be performed on the target platform, such as a transfer, remittance, or the like. The customer selects a target account transaction to be performed on the target platform, and the blockchain platform receives the account transaction request of the customer, queries the valid approval number of the customer, and performs the target account transaction according to the approval number.

[0042] In summary, the above-mentioned blockchain platform realizes online integrated management of account supervision and account operation of the fund supervision customer, avoids the customer submitting various paper materials offline, and improves the efficiency of the account transaction.

[0043] How to perform the account transaction processing through the approval number is crucial. In the transaction processing method based on the blockchain platform provided in the embodiments of the present application, the transaction processing of each account transaction according to each approval number includes the following contents: receiving a target account transaction request initiated by a target object, and determining a target approval number corresponding to the target account transaction request from a plurality of approval numbers; verifying the validity of the target approval number, if the verification of the target approval number is passed, freezing the target approval number, and generating a first channel number, wherein the first channel number is a number corresponding to the target platform generated according to a preset rule, the target object performs a target operation on the target platform to trigger the target account transaction request; processing the target account transaction according to the target approval number and the first channel number to obtain a processing result.

[0044] Querying, through the blockchain platform, a plurality of approval numbers corresponding to the target object and satisfying a preset requirement and target data information corresponding to each approval number; and returning the plurality of approval numbers satisfying the preset requirement and the target data information corresponding to each approval number to the target object.

[0045] Specifically, the customer (i.e., the target object described above) selects a target account transaction to be performed on the target platform, and the target platform sends a target account transaction request to the blockchain platform. The blockchain platform receives the target account transaction request described above, and queries, according to the target account transaction request, a plurality of approval numbers of the customer satisfying a preset requirement and target data information corresponding to each approval number. It should be noted that the preset requirement can be to determine whether the approval number is within a valid period and whether the use state of the approval number is an unused state.

[0046] The blockchain platform returns the plurality of approval numbers and the target data information corresponding to each approval number to the target platform, so that the customer selects the corresponding target approval number. After determining the target approval number corresponding to the target account transaction request from the plurality of approval numbers, the blockchain platform will again verify the validity of the target approval number, determine that the target approval number is valid, freeze the target approval number, and generate a first channel number. Finally, according to the target approval number and the first channel number, the target account transaction is processed to obtain a processing result.

[0047] It should be noted that the first channel number is a number corresponding to the target platform generated according to a preset rule, and the first channel number is used as a matching condition for subsequent unfreezing of the target approval number. The first channel number includes at least a channel type identifier and a timestamp to ensure uniqueness.

[0048] In summary, by freezing a unique target approval number to control the corresponding account transaction, the security of the target object account transaction is ensured, and all operations are online operations. The data of the platforms are automatically linked, which facilitates the target object to handle the business and improves the efficiency of the account transaction.

[0049] After the target account transaction is executed, the target approval number needs to be unfrozen and set, to avoid the target approval number being used repeatedly, which includes the following contents: receiving a processing result and a second channel number; according to the processing result and the second channel number, the target approval number is unfrozen and the use state of the target approval number is updated.

[0050] If the processing result is processing success, it is determined whether the second channel number is the same as the first channel number; if the second channel number is the same as the first channel number, the target approval number is unfrozen, and the use state of the target approval number is set to used; the unfreezing result of the target approval number is fed back to the target platform.

[0051] If the processing result is processing failure, it is determined whether the second channel number is the same as the first channel number; if the second channel number is the same as the first channel number, the target approval number is unfrozen, and the use state of the target approval number is set to unused; the unfreezing result of the target approval number is fed back to the target platform.

[0052] Specifically, after the target transaction is completed, the target approval number needs to be unfrozen and its status set to prevent it from being used repeatedly. The processing result of the target transaction and the second channel number are sent to the blockchain platform so that the blockchain platform can perform the corresponding processing on the target approval number based on the processing result and the second channel number. If the processing result is successful, i.e., the transaction is successful, it is then determined whether the second channel number is the same as the first channel number. If the second channel number is the same as the first channel number, the target approval number is unfrozen, and its usage status is set to used.

[0053] It should be noted that the channel number is checked to ensure that the target approval number is frozen and unfrozen for the same person, thereby further improving data security.

[0054] If the processing result is failure, i.e., the transaction fails, the system checks if the second channel number is the same as the first channel number. If they are the same, the target approval number is unfrozen, and its usage status is set to unused. Since the transaction was not successful, the target approval number is essentially unused, allowing the customer to re-execute the target transaction request using that number. This avoids the customer having to approve the transaction again, effectively improving business processing efficiency.

[0055] Optionally, in the transaction processing method based on a blockchain platform provided in the embodiments of this application, the method further includes: if the target platform does not receive the unfreezing result for the target approval number within a preset time, the target platform initiates periodic polling of the blockchain platform to determine the unfreezing status of the target approval number.

[0056] Specifically, the information exchange between the target platform and the blockchain platform is synchronous. However, due to network or other reasons, information discrepancies may occur. In such cases, the following steps can be taken: For example, when initiating a freeze, if the target platform does not receive the freeze processing result before the timeout, the target platform will periodically poll the blockchain platform to obtain the usage status of the approval number. The polling interval and number of polls can be configured according to actual needs. The default setting is to poll once every 5 seconds, with a maximum of 3 polls. If the final processing result is still not obtained after multiple polls, the target platform will process it as a "submission failed".

[0057] For example, when initiating an unfreezing process, if the target platform has not received the unfreezing result before the timeout, the target platform will add a separate thread to query the blockchain platform again for the approval number that has not been synchronized to the final state. If the unfreezing is successful, the relevant information on the target platform will be updated synchronously. If the unfreezing fails, business personnel will need to manually review and process the usage status of the approval number.

[0058] In summary, the above arrangement can avoid the phenomenon that the information interaction between the target platform and the blockchain platform is not synchronized, and also avoid the phenomenon that the transaction is repeatedly operated due to the information inequality.

[0059] The transaction processing method based on the blockchain platform provided by the embodiment of the application receives target data information of multiple dynamic account transactions uploaded by a target object through a blockchain platform, wherein the target data information at least includes payee information, payor information, transaction amount and transaction currency; the payee information, the payor information, the transaction amount and the transaction currency are evaluated for security and consistency through the blockchain platform to obtain an evaluation result; if the evaluation result is passed, a number is generated for each dynamic account transaction through the blockchain platform to obtain multiple approval numbers, and each approval number and the target data information corresponding to the approval number are stored to the blockchain platform; each dynamic account transaction is processed according to each approval number, which solves the problem in the related art that the dynamic account transaction of the customer under fund supervision needs to provide paper materials and be approved offline before the dynamic account transaction is executed, resulting in a relatively low dynamic account transaction efficiency. The fund dynamic account of the target customer under fund supervision is managed online through the blockchain platform, and the data that passes the evaluation is directly managed on the chain to achieve the purpose of data tamper resistance. An approval number is generated for each dynamic account transaction that passes the evaluation through the blockchain platform, and the dynamic account transaction processing is realized through the approval number, which avoids the target object from submitting various paper materials and performing offline approval, thereby achieving the effect of improving the dynamic account transaction efficiency.

[0060] It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a group of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described herein can be executed in an order different from that shown herein.

[0061] The embodiment of the application also provides a transaction processing system based on a blockchain platform. It should be noted that the transaction processing system based on the blockchain platform of the embodiment of the application can be used to execute the transaction processing method based on the blockchain platform provided by the embodiment of the application. The transaction processing system based on the blockchain platform provided by the embodiment of the application is introduced as follows.

[0062] Figure 2 is a schematic diagram of the transaction processing system based on the blockchain platform according to the embodiment of the application. As shown in Figure 2 the system includes a blockchain platform and a target platform. The customer under fund supervision (i.e. the target object described above) enters the target data information of each dynamic account transaction into the blockchain platform described above, and the target data information at least includes payee information, payor information, transaction amount, transaction currency and other data information.

[0063] In the case of passing the evaluation result, the blockchain platform generates a corresponding approval number for each dynamic account transaction passing the evaluation, and stores each approval number and the target data information corresponding to each approval number on the blockchain platform, and uses the tamper-proof and mutual trust mechanism of the blockchain platform to register and manage the target data information. The approval number generated by the blockchain platform executes the corresponding dynamic account transaction.

[0064] The blockchain platform performs security evaluation and consistency audit on the above-mentioned target data information such as payer information, payee information, transaction amount and transaction currency. The customer can select a dynamic account transaction to be performed on the target platform, such as a transfer, remittance, etc. The customer selects a target dynamic account transaction to be executed on the target platform, and the blockchain platform queries the valid approval number of the customer after receiving the dynamic account transaction request of the customer, and executes the target dynamic account transaction according to the approval number.

[0066] It should be noted that the target platform can also be used for the internal financial approval link of the customer, as shown in Figure 2 , after submitting the dynamic account transaction request, the batch transaction processing is executed. The batch transaction processing is the internal financial approval link of the customer, and the dynamic account transaction processing is executed after the batch transaction processing.

[0067] In summary, through the above-mentioned transaction processing system based on the blockchain platform, the customer does not need to go to the bank to handle, and the teller and the third party involved in the organization such as the banking supervision department do not need to communicate offline, which improves the efficiency of the dynamic account transaction processing. And the data after the approval is stored on the chain, and the tamper-proof and mutual trust mechanism of the blockchain enhances the credibility and reliability of the supervision data.
