Description

Technical Field

[0001] The present application relates to the field of data processing technology, and in particular to a blockchain-based annuity data supervision method, device, equipment and medium. Background Art

[0002] In the process of annuity management and operation, the trustee shall promptly and effectively deal with the violations, errors, and anti-statute of limitations claims of other managers. If a violation occurs, the trustee shall work with other management agencies to effectively control the potential risks or losses caused by the violation, record the violation and the process of occurrence during the accident handling process, and investigate the party at fault. If the risk has already occurred and caused losses to the annuity, the principal shall deal with the defaulting institution accordingly. At the same time, the trustee shall negotiate with the principal to decide whether to replace the defaulting institution. At present, when managing annuities, reporting and supervision are mostly done through emails, and many processes involve human intervention, resulting in low timeliness and difficulty in ensuring security and authenticity.

[0003] When correcting errors and seeking compensation during the annuity management process, after discovering errors, the correction and adjustment are also done through email. The entire process is uncontrollable, and the relevant responsible persons may cheat and falsify, making it difficult to ensure the fairness and reliability of the supervision process. For example, the regulatory authorities discovered that the investment manager used a large amount of funds to purchase risky assets such as bonds with default risks. After being notified by the regulatory authorities, the investment manager did not adjust the investment assets in accordance with the regulations, but instead forged data together with the custodian and sent the falsified data to the regulatory authorities, which ultimately led to the loss of the client's assets. After the result occurred, due to the lack of a credible notarization platform, the investment manager and the custodian blamed each other, and may even put the blame on the trustee.

[0004] It can be seen that in the prior art, in the process of annuity management, when data reporting and data error correction are performed by sending emails, there are problems such as low timeliness and difficulty in ensuring the fairness, security and reliability of supervision. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] It should be understood that the references to "one embodiment" or "an embodiment" throughout the specification mean that the specific features, structures, or characteristics associated with the embodiment are included in at least one embodiment of the present application. Therefore, the references to "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0029] In the prior art, in the annuity management process, data reporting and data error correction are performed by sending emails offline, which requires human intervention, has the problem of poor timeliness, and the fairness, security and reliability of supervision are difficult to guarantee. In view of the above situation, the embodiment of the present application provides an annuity data supervision method based on blockchain, relying on blockchain, the supervision verification platform publishes the annuity supervision rules on the chain, and ensures the fairness and authenticity of the annuity supervision rules. Each management node creates a reporting subsystem based on the annuity supervision rules, and calls the daily settlement reporting data through the remote procedure call protocol (Remote Procedure Call Protocol, RPC), and automatically reports to the supervision verification platform. The supervision verification platform verifies the reporting data according to the annuity supervision rules, and publicizes the verification results on the chain. The management node performs corresponding processing according to the verification results, and appends the processing results to the chain, which can reduce human intervention and the process of sending files and communicating offline, and improve the efficiency of the entire supervision process. At the same time, by putting the verification results and processing results on the chain, offline fraud and other situations are avoided, and the fairness, fairness and security of the supervision process are guaranteed.

[0030] In the annuity business scenario, the custody node refers to the equipment corresponding to the custodian. The custodian accepts the entrustment of the trustee to keep the annuity fund property, such as a banking institution; the investment management node refers to the equipment corresponding to the investment manager. The investment manager accepts the entrustment of the trustee to invest and manage the annuity fund property, such as a professional investment management institution; the trustee node refers to the equipment corresponding to the trustee. The trustee is entrusted with the management of the annuity fund property, such as a legal trustee institution such as a pension management company that complies with national regulations.

[0031] The following is an introduction to the annuity data supervision method based on blockchain provided in the embodiment of the present application. The annuity data supervision method based on blockchain in the embodiment of the present application is applied to the supervision verification platform, see Figure 1 As shown, the supervision verification platform is deployed on the entrusted node, the entrusted node, the custodian node, the investment management node and the blockchain platform node are nodes in the blockchain system, and the supervision verification platform is connected to the custodian node and the investment management node in communication, and the entrusted node, the custodian node and the investment management node are connected to the blockchain platform node respectively, see Figure 2 As shown, the method includes:

[0032] Step 201: upload the annuity supervision rules to the blockchain platform node, and the annuity supervision rules are issued by the blockchain platform node to the entrusted node, the custodian node and the investment management node.

[0033] After determining the annuity supervision rules, the supervision verification platform deployed on the trustee node uploads the annuity supervision rules to the blockchain platform node. The annuity supervision rules in the embodiment of the present application can be supervision rules related to enterprise annuities or occupational annuities. After uploading the annuity supervision rules to the blockchain platform node, the blockchain platform node sends the received annuity supervision rules to each management node, that is, to the trustee node, the custody node and the investment management node.

[0034] It should be noted that the regulatory verification platform is deployed on the trusted nodes, so the trusted nodes can obtain the annuity regulatory rules determined by the regulatory verification platform offline. In order to ensure the fairness and impartiality of data distribution, the blockchain platform nodes need to issue annuity regulatory rules to the trusted nodes, custodial nodes and investment management nodes when issuing them.

[0035] Step 202: Receive first reporting data respectively sent by the entrusted node, the custodian node and the investment management node based on the annuity supervision rules.

[0036] After receiving the annuity supervision rules, the trustee node, the custodian node and the investment management node determine the corresponding data format based on the annuity supervision rules, generate the corresponding first reporting data, and send it to the supervision verification platform. By determining the corresponding data format based on the annuity supervision rules, it is convenient for the supervision verification platform to quickly verify the data. The first reporting data reported by the trustee node, the custodian node and the investment management node are all data associated with the annuity. And by sending the annuity supervision rules to each management node, each management node can generate and report the first reporting data with reference to the annuity supervision rules.

[0037] When receiving the first reporting data, the regulatory verification platform can receive the first reporting data sent by the custodian node and the investment management node respectively based on the communication connection with the custodian node and the investment management node. For the entrusted node, the regulatory verification platform can receive the first reporting data sent by the entrusted node based on the communication connection with the entrusted node, and since the regulatory verification platform is deployed on the entrusted node, the transmission of the first reporting data can also be completed through internal interaction between the two, wherein the data format corresponding to the transmitted first reporting data matches the data format required by the annuity regulatory rules.

[0038] Step 203: Verify the first reported data according to the annuity regulatory rules to obtain a first verification result, and send the first verification result to the blockchain platform node. The first verification result is sent by the blockchain platform node to the entrusted node, the custodian node and the investment management node.

[0039] After receiving the first reporting data respectively sent by the entrusted node, the custodian node and the investment management node based on the annuity regulatory rules, the regulatory verification platform verifies the received first reporting data according to the annuity regulatory rules and obtains a first verification result. Based on the first verification result, it can be determined whether there is first reporting data that does not match the annuity regulatory rules, wherein the first reporting data that does not match the annuity regulatory rules is the first reporting data with abnormalities.

[0040] After obtaining the first verification result, the supervision verification platform will send the first verification result to the blockchain platform node. The blockchain platform node will send the received first verification result to the entrusted node, custodian node and investment management node, so as to put the first verification result on the chain and ensure the openness and transparency of the supervision process.

[0041] For the entrusted nodes, since the regulatory verification platform is deployed on the entrusted nodes, the entrusted nodes can obtain the first verification results determined by the regulatory verification platform offline. In order to ensure the fairness and impartiality of data distribution, the blockchain platform nodes need to send the first verification results to the entrusted nodes, custodial nodes and investment management nodes when sending them.

[0042] The first verification result includes the first sub-verification result associated with the entrusted node, the second sub-verification result associated with the custodian node, and the third sub-verification result associated with the investment management node. After obtaining the first verification result, the entrusted node can check the first sub-verification result to determine whether the uploaded first report data has any abnormality; after obtaining the first verification result, the custodian node can check the second sub-verification result to determine whether the uploaded first report data has any abnormality; after obtaining the first verification result, the investment management node can check the third sub-verification result to determine whether the uploaded first report data has any abnormality.

[0043] Step 204: When the first verification result does not meet the verification criteria, receive the second reporting data re-uploaded by at least one of the entrusted node, the custodian node and the investment management node, perform data verification on the second reporting data according to the annuity regulatory rules to obtain a second verification result, and send the second verification result to the entrusted node, the custodian node and the investment management node through the blockchain platform node.

[0044] When it is determined through data verification that there is first filing data that does not match the annuity regulatory rules in the first filing data uploaded by the entrusted node, the custodian node, and the investment management node, it is determined that the first verification result does not meet the verification standard. The verification standard is determined based on the annuity regulatory rules, and the verification standard includes the first sub-standard corresponding to the entrusted node, the second sub-standard corresponding to the custodian node, and the third sub-standard corresponding to the investment management node. The first verification result does not meet the verification standard, which may be at least one of the first sub-verification result does not meet the first sub-standard, the second sub-verification result does not meet the second sub-standard, and the third sub-verification result does not meet the third sub-standard.

[0045] For the entrusted nodes, custodian nodes and investment management nodes, when they receive the first verification result and check it and determine that the first verification result does not meet the verification criteria, they can re-upload the second reporting data, which is the data associated with the annuity.

[0046] The nodes that upload the second report data may include nodes with abnormalities in the first report data and nodes without abnormalities in the first report data. For nodes with abnormalities in the first report data, the second report data uploaded is the data obtained after modifying the first report data. For nodes without abnormalities in the first report data, the second report data uploaded is the first report data. In this case, all nodes need to re-upload data.

[0047] The nodes that upload the second report data may also only include the nodes where the first report data has abnormalities. In this case, the uploaded second report data is the data obtained after modifying the first report data. In this case, only the nodes where the first report data has abnormalities need to re-upload the data.

[0048] It can be seen that the second report data received by the supervision and verification platform includes at least the modified report data, and may also include the unmodified first report data when including the modified report data. The specific situation needs to be determined according to the rules for re-uploading data. When only the node with abnormal first report data needs to re-upload data, the second report data received at this time includes the modified report data; when all nodes need to re-upload data, the second report data received at this time includes the modified report data and the unmodified first report data.

[0049] The regulatory verification platform verifies the second reporting data received according to the annuity regulatory rules and obtains a second verification result. Based on the second verification result, it can be determined whether there is second reporting data that does not match the annuity regulatory rules, among which the second reporting data that does not match the annuity regulatory rules is the second reporting data with abnormalities.

[0050] After obtaining the second verification result, the supervision verification platform sends the second verification result to the blockchain platform node. The blockchain platform node sends the received second verification result to each management node (trusted node, custodial node and investment management node), so as to upload the second verification result obtained after data error correction and data verification to the chain, thereby ensuring the openness and transparency of the supervision process.

[0051] It should be noted that, for any of the entrusted nodes, custodian nodes and investment management nodes, after receiving the first verification result, if it is determined that there is an abnormality in the uploaded first reporting data, the first reporting data can be re-uploaded without modifying the first reporting data. For the supervision and verification platform, the verification of the re-uploaded first reporting data can continue until the confirmation information sent by the management node that it will not be modified is received. The supervision and verification platform can stop the re-verification and only retain the verification records and verification results.

[0052] The above-mentioned implementation process of the present application can realize the chain-up of the annuity regulatory rules by uploading the annuity regulatory rules to the blockchain platform node, thereby ensuring the fairness and authenticity of the annuity regulatory rules. After the blockchain platform node sends the annuity regulatory rules to each management node, it can be convenient for each management node to upload the reporting data in the corresponding data form based on the annuity regulatory rules to ensure the verification efficiency of the regulatory verification platform; the regulatory verification platform will publicize the first verification result on the chain after obtaining it, and when the management node re-uploads the reporting data according to the first verification result, the regulatory verification platform will verify the data again and upload the verification result to the chain, which can avoid offline fraud and the like, ensure the fairness, equity and security of the regulatory process, and at the same time improve the timeliness of data processing.

[0053] In an optional embodiment of the present application, uploading the annuity supervision rules to the blockchain platform node includes: generating the annuity supervision rules according to the target supervision requirements, and uploading the annuity supervision rules to the blockchain platform node; wherein, in the event that the target supervision requirements change, updating the annuity supervision rules, and uploading the updated annuity supervision rules to the blockchain platform node, and the blockchain platform node sends the updated annuity supervision rules to the entrusted node, the custodian node and the investment management node.

[0054] The supervision verification platform first generates annuity supervision rules based on the target supervision requirements, where the target supervision requirements can be determined based on the requirements of the Ministry of Human Resources and Social Security and the supervision requirements of the trustee. For example, the requirements of the Ministry of Human Resources and Social Security include: assets allocated to liquid assets are less than 20% of the total assets, and investment in default risk bonds is not allowed. After the annuity supervision rules are generated based on the target supervision requirements, the annuity supervision rules are uploaded to the blockchain platform node so that the blockchain platform node sends the received annuity supervision rules to each management node to realize the chaining and distribution of the annuity supervision rules. By publishing the annuity supervision rules on the chain, the fairness and authenticity of the annuity supervision rules are guaranteed.

[0055] In the event of a change in the target regulatory requirements, such as a change in the requirements of the Ministry of Human Resources and Social Security and / or the trustee's regulatory requirements, the regulatory verification platform regenerates the annuity regulatory rules based on the changed target regulatory requirements to update the annuity regulatory rules. The regulatory verification platform can regularly detect whether the target regulatory requirements have changed, so that when it is determined that the target regulatory requirements have changed, the annuity regulatory rules can be quickly updated, and the regulatory verification platform can also receive notification information when the target regulatory requirements have changed, and quickly update the annuity regulatory rules based on the notification information.

[0056] After the update of the annuity regulatory rules is completed, the updated annuity regulatory rules are uploaded to the blockchain platform node, and the blockchain platform node sends the updated annuity regulatory rules to the trustee node, the custody node and the investment management node, so as to realize the update of the annuity regulatory rules on the chain and in each management node. Among them, the annuity regulatory rules include a main data structure and a sub-data structure. The main data structure is used to record the main information of the annuity regulatory rules, and the sub-data structure is used to record the relevant content for each management node. The main data structure can be seen in Table 1, and the sub-data structure can be seen in Table 2.

[0057]

[0058] Table 1

[0059]

[0060] Table 2

[0061] The following is an example of the main data structure of the next year's financial regulatory rules, as shown in Table 3.

[0062]

[0063] Table 3

[0064] In the above implementation process, after obtaining the target regulatory requirements, the regulatory verification platform generates annuity regulatory rules based on the target regulatory requirements, which can ensure the rationality and reliability of the annuity regulatory rules. In the event of changes in the target regulatory requirements, the annuity regulatory rules are updated and the updated annuity regulatory rules are put on the chain to complete the update of the annuity regulatory rules at each management node, thus ensuring the timeliness of data updates.

[0065] In an optional embodiment of the present application, the receiving of first reporting data respectively sent by the entrusted node, the custodian node, and the investment management node based on the annuity supervision rule includes:

[0066] receiving first reporting data including annuity asset allocation plan sent by the first reporting subsystem after the entrusted node creates the first reporting subsystem based on the annuity supervision rule;

[0067] Receiving first reporting data including daily reconciliation information sent by the second reporting subsystem after the escrow node creates the second reporting subsystem based on the annuity supervision rules;

[0068] Receiving first reporting data including daily transaction records sent by the third reporting subsystem after the investment management node creates the third reporting subsystem based on the annuity supervision rules;

[0069] Among them, the supervision and verification platform is communicatively connected with the first reporting subsystem, the second reporting subsystem and the third reporting subsystem.

[0070] For each management node (trustee node, custodian node and investment management node), after receiving the annuity supervision rules, a corresponding reporting subsystem can be created according to the annuity supervision rules to facilitate uploading of reporting data to the supervision verification platform through the reporting subsystem. Since the reporting subsystem is created based on the annuity supervision rules, the reporting data uploaded through the reporting subsystem complies with the data format required by the annuity supervision rules.

[0071] The reporting subsystem created by each management node is connected to the supervision and verification platform. Figure 3 As shown, the first reporting subsystem corresponding to the entrusted node, the second reporting subsystem corresponding to the custodian node, and the third reporting subsystem corresponding to the investment and management node are respectively connected to the supervision and verification platform for communication.

[0072] When receiving the first reporting data sent by the trustee node based on the annuity regulatory rules, after the trustee node creates the first reporting subsystem based on the annuity regulatory rules, based on the communication connection between the first reporting subsystem and the regulatory verification platform, the first reporting data including the annuity asset allocation plan is sent. When receiving the first reporting data sent by the custodian node based on the annuity regulatory rules, after the trustee node creates the second reporting subsystem based on the annuity regulatory rules, based on the communication connection between the second reporting subsystem and the regulatory verification platform, the first reporting data including the daily reconciliation information is sent, wherein the daily reconciliation information is the daily reconciliation information corresponding to the annuity data. When receiving the first reporting data sent by the investment management node based on the annuity regulatory rules, after the investment management node creates the third reporting subsystem based on the annuity regulatory rules, based on the communication connection between the third reporting subsystem and the regulatory verification platform, the first reporting data including the daily transaction records is sent, wherein the daily transaction records are the daily transaction records corresponding to the annuity data.

[0073] In the above implementation process, each management node creates a corresponding reporting subsystem, and based on the communication connection between the supervision and verification platform and the reporting subsystem, receives the first reporting data uploaded by each management node through the reporting subsystem. It can receive the reporting data in a data format that meets the requirements of the annuity supervision rules to ensure the data verification efficiency of the supervision and verification platform.

[0074] Among them, when receiving the re-uploaded second report data, you can receive the second report data re-uploaded by three management nodes respectively, or you can only receive the second report data re-uploaded by the management node where there is an abnormality in the first report data. The situation of receiving the second report data re-uploaded by at least one management node is introduced below.

[0075] Optionally, the receiving the second reporting data re-uploaded by at least one of the entrusted node, the hosting node and the investment node includes:

[0076] receiving the second report data determined after the first report data is modified and re-uploaded by the first target node, and receiving the second report data identical to the first report data and re-uploaded by the second target node; or

[0077] Receiving the second report data determined after the first report data is modified and re-uploaded by the first target node;

[0078] Among them, the first reporting data corresponding to the first target node does not match the annuity supervision rules, the first reporting data corresponding to the second target node matches the annuity supervision rules, the first target node includes at least one node among the trusted node, the custodial node and the investment management node, and the second target node includes the remaining nodes among the trusted node, the custodial node and the investment management node.

[0079] When receiving the second report data re-uploaded by the three management nodes respectively, the second report data re-uploaded by the first target node and the second report data re-uploaded by the second target node can be received. Among them, the first target node is the management node where the first report data has an abnormality, and the number of first target nodes is at least one, and the second target node is the management node where the first report data does not have an abnormality, and the number of second target nodes can be zero or two. The existence of an abnormality in the first report data means that the first report data does not match the annuity supervision rules, and correspondingly, the absence of an abnormality in the first report data means that the first report data matches the annuity supervision rules.

[0080] For the first target node, the re-uploaded second reporting data is obtained by modifying the first reporting data. For the second target node, the re-uploaded second reporting data is the first reporting data.

[0081] After obtaining the second reporting data uploaded by the three management nodes, the regulatory verification platform re-uploads the second reporting data of the first target node and the second target node for data verification according to the annuity regulatory rules, obtains the second verification results and uploads them to the blockchain platform node, which distributes the second verification results to each management node, thereby realizing the chain-up and distribution of the second verification results.

[0082] In case there is an abnormality in the first reported data corresponding to the trusted node, the first target node includes the trusted node, and the second target node includes the custodial node and the investment management node; in case there is an abnormality in the first reported data corresponding to the custodial node, the first target node includes the custodial node, and the second target node includes the trusted node and the investment management node; in case there is an abnormality in the first reported data corresponding to the investment management node, the first target node includes the investment management node, and the second target node includes the trusted node and the custodial node.

[0083] Of course, it can also be that the first reporting data corresponding to the entrusted node and the investment management node is abnormal, the first reporting data corresponding to the entrusted node and the custodian node is abnormal, the first reporting data corresponding to the custodian node and the investment management node is abnormal, or the first reporting data corresponding to the entrusted node, the custodian node and the investment management node is abnormal. For the above situations, the specific management nodes corresponding to the first target node and the second target node are not elaborated here one by one.

[0084] By receiving the second reporting data re-uploaded by each management node respectively, and verifying and obtaining the second verification result based on the obtained second reporting data, data verification can be performed based on the same verification method as the first reporting data, thereby ensuring the uniformity of the style of the obtained verification results.

[0085] When receiving the second reporting data re-uploaded by the management node that contains anomalies in the first reporting data, only the first reporting data re-uploaded by the first target node may be received, and the received second reporting data may be verified according to the annuity supervision rules, and the second verification result may be obtained and uploaded to the blockchain platform node, which will distribute the second verification result to each management node, thereby realizing the chain-up and distribution of the second verification result.

[0086] Among them, in the case where there is an abnormality in the first reported data corresponding to the trusted node, the first target node includes the trusted node; in the case where there is an abnormality in the first reported data corresponding to the custodial node, the first target node includes the custodial node; in the case where there is an abnormality in the first reported data corresponding to the investment and management node, the first target node includes the investment and management node; in the case where there is an abnormality in the first reported data corresponding to the trusted node and the custodial node, the first target node includes the trusted node and the investment and management node; in the case where there is an abnormality in the first reported data corresponding to the custodial node and the investment and management node, the first target node includes the trusted node and the investment and management node; in the case where there is an abnormality in the first reported data corresponding to the custodial node and the investment and management node, the first target node includes the custodial node and the investment and management node; in the case where there is an abnormality in the first reported data corresponding to the trusted node, the custodial node and the investment and management node, the first target node includes the trusted node, the custodial node and the investment and management node.

[0087] Among them, when there are exceptions in the first reporting data corresponding to the three management nodes, there is no second target node, and both solutions protect the second reporting data re-uploaded by the three management nodes.

[0088] By only receiving the second report data re-uploaded by the management node with an abnormality in the first report data, compared with the situation of receiving the second report data re-uploaded by all management nodes, the data verification pressure can be reduced and the verification efficiency can be improved.

[0089] In the above implementation process, by receiving the second report data re-uploaded by each management node, data verification can be performed based on the same verification method as the first report data, thereby ensuring the uniformity of the style of the obtained verification results; by only receiving the second report data re-uploaded by the management node where there is an abnormality in the first report data, the data verification pressure can be reduced and the verification efficiency can be improved; and this embodiment provides two methods for data retransmission, enriching the data retransmission methods.

[0090] In an optional embodiment of the present application, when the second verification result does not meet the verification standard, receiving the target reporting data re-uploaded by at least one of the entrusted node, the hosting node and the investment management node;

[0091] According to the annuity supervision rules, the target reporting data is verified to obtain a target verification result, and the target verification result is sent to the entrusted node, the custodian node and the investment management node through the blockchain platform node;

[0092] If the target verification result does not meet the verification criteria, return to the step of receiving the target filing data re-uploaded by at least one of the entrusted node, the custodian node and the investment management node until a verification result meeting the verification criteria is obtained or the first confirmation information fed back by the third target node through the blockchain platform node is received;

[0093] The reporting data received each time are distinguished, the third target node is the node where the latest reporting data uploaded has an abnormality, and the first confirmation information is used to indicate not to re-upload the reporting data.

[0094] After step 204, if the second verification result does not meet the verification criteria, it is necessary to receive the target reporting data (such as target reporting data 1) re-uploaded by at least one of the trusted node, the custodial node and the investment and management node. The target reporting data received this time is different from the second reporting data and the first reporting data received. At least one of the trusted node, the custodial node and the investment and management node re-uploads the target reporting data after modifying the data.

[0095] It should be noted that the target reporting data can be uploaded by the node with abnormal second reporting data, or by all management nodes. The second verification result not meeting the verification standard can be at least one of the following: the sub-verification result corresponding to the entrusted node does not meet the first sub-standard, the sub-verification result corresponding to the custodian node does not meet the second sub-standard, and the sub-verification result corresponding to the investment management node does not meet the third sub-standard.

[0096] For the target reporting data received this time, data verification can continue to be carried out according to the annuity supervision rules to obtain the corresponding target verification results, and the target verification results can be sent to each management node through the blockchain platform node. If the target verification result obtained this time still does not meet the verification criteria, it is necessary to continue to receive the target reporting data (such as target reporting data 2) re-uploaded by at least one of the entrusted node, the custodian node and the investment management node. The target reporting data received this time is different from the reporting data received three times before, that is, each time the reporting data is received, it is different from the reporting data received before, and then continue to execute the data verification process to send the corresponding target verification result to each management node through the blockchain platform node. If the target verification result obtained this time still does not meet the verification criteria, continue to receive the re-uploaded target reporting data (such as target reporting data 3) that is different from the reporting data uploaded several times before, until the verification result that meets the verification criteria is obtained (it can be that the sub-verification result corresponding to the entrusted node meets the first sub-standard, the sub-verification result corresponding to the custodian node meets the second sub-standard, and the sub-verification result corresponding to the investment management node meets at least one of the third sub-standards), or, receive the first confirmation information fed back by the third target node through the blockchain platform node to indicate that the reporting data will not be re-uploaded.

[0097] If the first confirmation information is received from the third target node (the node with the latest reported data uploaded containing anomalies), it is determined that the third target node will no longer modify the data. At this time, the supervision and verification platform can stop verifying the group of reported data.

[0098] Each time the management node re-uploads the reporting data, all the management nodes may re-upload the data respectively, or the management node whose reporting data was abnormal in the previous upload may re-upload the data.

[0099] In the above implementation process, if the verification result does not meet the verification standard, the process of receiving the re-uploaded reporting data, performing data verification and distributing the verification result is executed in a loop until a verification result that meets the verification standard is obtained, or the first confirmation information is received, and effective data correction can be performed based on the data verification.

[0100] In an optional embodiment of the present application, after obtaining the verification results that meet the verification standards, it also includes: receiving second confirmation information fed back by at least one of the entrusted node, the custodian node and the investment management node through the blockchain platform node; wherein the second confirmation information is used to indicate that the reporting data corresponding to the current node has passed the verification.

[0101] If the first verification result meets the verification standards, the second confirmation information can be received from the entrusted node, the custodian node and the investment management node respectively through the blockchain platform node. The supervision verification platform can determine that the supervision of this group of data is completed based on the second confirmation information respectively fed back by the three management nodes, while ensuring the fairness and reliability of the supervision process.

[0102] For each management node, when it is determined that the sub-verification result corresponding to the management node meets the corresponding standard, the second confirmation information can be fed back. Therefore, in the case where the second verification result meets the verification standard, after it is determined that the second verification result meets the verification standard, the second confirmation information fed back by at least one of the entrusted node, the custodial node and the investment management node through the blockchain platform node can be received; accordingly, in the case where it is determined that the verification result meets the verification standard after three or more verifications, after it is determined that the verification result meets the verification standard, the second confirmation information fed back by at least one of the entrusted node, the custodial node and the investment management node can be received.

[0103] In the above implementation process, the supervision verification platform can further ensure the fairness and reliability of the supervision process by receiving the second confirmation information fed back by the management node.

[0104] The data structure of the verification result is introduced below, and the details can be seen in Table 4.

[0105]

[0106] Table 4

[0107] The following example illustrates the data structure of the verification results, see Table 5 and Table 6, where Table 5 is the data structure of the verification results corresponding to the regulatory verification platform, and Table 6 is the data structure of the verification results corresponding to the management node. For the management node, the relevant content can be replied to the regulatory verification platform through the blockchain platform node, and the reply format is shown in Table 6.

[0112] The following is an elaboration of the annuity data supervision method based on blockchain provided by the embodiment of the present application through a specific implementation process, see Figure 4 shown.

[0113] Regulatory verification platform: Generate annuity regulatory rules based on target regulatory requirements and upload them to the blockchain platform node. Update annuity regulatory rules when target regulatory requirements change.

[0114] Blockchain platform nodes: distribute annuity regulatory rules to trustee nodes, custodian nodes and investment management nodes.

[0115] Trustee node: Create a first reporting subsystem that communicates with the supervision and verification platform according to the annuity supervision rules, and send the first reporting data including the annuity asset allocation plan through the first reporting subsystem.

[0116] Custody node: Create a second reporting subsystem that communicates with the regulatory verification platform in accordance with the annuity regulatory rules, and send the first reporting data including daily reconciliation information through the second reporting subsystem.

[0117] Investment management node: Create a third reporting subsystem that communicates with the regulatory verification platform in accordance with annuity regulatory rules, and send the first reporting data including daily transaction records through the third reporting subsystem.

[0118] Supervision and verification platform: verify the first reporting data uploaded by the entrusted nodes, custodian nodes and investment management nodes to obtain the first verification results, and upload the first verification results to the blockchain platform nodes.

[0119] Blockchain platform node: Send the first verification result to the entrusted node, custodian node and investment management node.

[0120] Trustee nodes, custodian nodes and investment management nodes: Determine whether it is necessary to re-upload the second reporting data based on the first verification results. If not, upload additional confirmation information to the blockchain platform node; otherwise, re-upload the second reporting data.

[0121] Supervision and verification platform: continue to verify data based on the second reporting data received, obtain the second verification results and upload them to the blockchain platform node.

[0122] The above process combines the annuity supervision process with blockchain and uploads relevant data to the chain, ensuring the security, authenticity, fairness and impartiality of the supervision process, while ensuring the rationality and security of annuity asset investment and protecting the rights and interests of the client to the greatest extent.

[0123] The above is the overall implementation process of the blockchain-based annuity data supervision method provided in the embodiment of the present application. By uploading the annuity supervision rules to the blockchain platform node, the annuity supervision rules can be uploaded to the chain, ensuring the fairness and authenticity of the annuity supervision rules. After the blockchain platform node sends the annuity supervision rules to each management node, it can be convenient for each management node to upload the reporting data in the corresponding data form based on the annuity supervision rules to ensure the verification efficiency of the supervision verification platform; after obtaining the first verification result, the supervision verification platform will publish it on the chain. When the management node re-uploads the reporting data according to the first verification result, the supervision verification platform will perform data verification again and upload the verification result to the chain, which can avoid offline fraud and ensure the fairness, equity and security of the supervision process.

[0124] Furthermore, by generating annuity regulatory rules based on target regulatory requirements, the rationality and reliability of annuity regulatory rules can be guaranteed. When the target regulatory requirements change, the annuity regulatory rules can be updated to ensure the timeliness of data updates. By receiving reported data in a data format that meets the requirements of annuity regulatory rules, the data verification efficiency of the regulatory verification platform can be guaranteed. By providing two methods for data retransmission, the data retransmission methods are enriched. By cyclically executing the process of receiving re-uploaded reported data, performing data verification and distributing verification results, effective data correction can be performed based on data verification. By receiving the second confirmation information fed back by the management node, the fairness and reliability of the regulatory process can be further guaranteed.
