[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0043] With the continuous development of the financial sector, in order to facilitate the supervision and auditing of financial data on various financial platforms, each financial platform can upload processed financial data to the blockchain, and the auditor can directly obtain the required financial data from the blockchain.

[0044] However, due to the frequent changes in financial processing rules, directly uploading processed financial data to the blockchain can lead to a mismatch between the financial data and the financial processing rules, thereby reducing the reliability of financial data acquisition.

[0045] Based on this, in an exemplary embodiment, a resource processing method is provided. Taking the application of this method to a blockchain node as an example, it can be executed by a data query platform, a blockchain node, where various financial platforms, auditors, and the data query platform can jointly participate in the blockchain. Figure 1 As shown, the specific steps include:

[0046] S101, in response to a data query request initiated by a data requester for a target business, retrieves the event ledger corresponding to the target business from the blockchain.

[0047] In this context, the "data requester" refers to the blockchain node that needs to query resource data, which can be various financial platforms or auditors. The "target business" refers to the financial business that needs to be queried, such as loan repayment or tax calculation. The "data query request" is the request to perform a data query.

[0048] An event ledger is a persistent storage unit that stores an ordered, immutable sequence of events, which can be implemented using blockchain. The event ledger contains real resource processing information corresponding to at least one user business event related to a target business. Furthermore, a user business event is a business action initiated by a user for the target business, such as a loan repayment. Real resource processing information refers to the actual information regarding resource processing involved in the business action; these resources can be financial resources, for example, the actual repayment amount.

[0049] Understandably, to ensure that the data stored in the blockchain can adapt to complex and ever-changing financial processing rules, the data stored in the blockchain can be changed from calculated financial data to unprocessed real resource processing information. For example, for a resource borrowing transaction, after repaying 100 yuan, the remaining repayment amount for the resource borrowing transaction is 1000 yuan. In related technologies, "remaining repayment amount of 1000 yuan" can be stored in the blockchain, while in this embodiment, "repayment of 100 yuan" is stored in the blockchain.

[0050] It's worth noting that, to ensure efficient data storage, the granularity of event uploading can be adaptively adjusted. An event can be generated for each business action, or actions over a period of time can be aggregated into a composite event to optimize performance and storage costs.

[0051] Optionally, when a data requester has a data query requirement for a target business, they can initiate a data query request for the target business through the blockchain node associated with the data requester, based on the business identification information of the target business and the data query requirement.

[0052] Upon detecting a data query request, the business identifier information of the target business can be obtained from the request. Then, based on this business identifier information, the event ledger corresponding to the target business can be retrieved from the blockchain.

[0053] S102 invokes the resource processing smart contract to process the real resource processing information in the event ledger, obtains the resource calculation results, and feeds back the resource calculation results to the data requester.

[0054] In this context, a resource processing smart contract is a smart contract with resource processing capabilities; for example, it may include contract code corresponding to financial processing rules. The resource calculation result is the resource information obtained after calculating the actual resource processing information.

[0055] In one alternative implementation, the calculation rules contained in the resource processing smart contract can be invoked to calculate the actual resource processing information in the event ledger, thereby obtaining the resource calculation result. For example, in cases where the data query requirement is a query request involving only business actions, such as querying the total repayment amount, the calculation formula contained in the resource processing smart contract can be invoked to calculate the actual resource processing information, thereby obtaining the resource calculation result.

[0056] Understandably, to ensure the rationality of resource calculation, the target business will be associated with business description information, such as the resource borrowing amount in a resource borrowing business. Therefore, in another optional implementation, the calculation rules contained in the resource processing smart contract can be invoked based on the business description information of the target business to calculate the actual resource processing information in the event ledger, thereby obtaining the resource calculation result. For example, in cases where the data query requirement is a query for the amount to be repaid, which involves basic business information, the calculation formula contained in the resource processing smart contract can be invoked to calculate the actual resource processing information based on the business description information of the target business, thereby obtaining the resource calculation result.

[0057] Furthermore, after determining the resource calculation results, these results can be fed back to the data requester. For example, the resource calculation results can be displayed on a designated page associated with the data requester, allowing them to access them.

[0058] For example, refer to Figure 2 The diagram illustrates a blockchain structure. When Bank A makes a repayment, its corresponding client A can encapsulate the repayment action into a structured event A'. This event contains factual information such as the resource borrowing business ID, the repayment amount, and a timestamp. This event is an atomic fact record that occurs in the business domain and has business significance; it is immutable.

[0059] Furthermore, client A signs event A' using its bank private key and broadcasts it to the consortium blockchain network. At this point, the ledger nodes in the blockchain use the consensus mechanism in the consensus layer to sort event A' among other events and package it into blocks, forming an immutable and ordered event ledger. Depending on the trade-off between performance and decentralization, consensus mechanisms can be implemented using algorithms such as Proof of Authority (PoA), Raft Consensus Algorithm (RAFT), or Istanbul Byzantine Fault Tolerance (IBFT).

[0060] Auditor C can initiate a data query request for business D through the Auditor C node in the blockchain. Subsequently, the nodes in the blockchain can call the resource processing smart contract to calculate the actual resource processing information corresponding to business D in the event ledger, obtain the resource calculation result, and feed the resource calculation result back to Auditor C. At this point, the auditor can independently verify the entire resource calculation process, upgrading the audit from "result verification" to "process reproduction," thereby ensuring the reliability of the audit results.

[0061] It is worth noting that since the blockchain no longer stores the results of financial resources, when querying data, it is necessary to replay the event chain through smart contracts to dynamically deduce the resource calculation results. Therefore, the method in this embodiment supports state tracing at any historical point in time and data reconstruction under rule changes, thereby ensuring the reliability of resource calculation.

[0062] Furthermore, since both the resource processing smart contract and the event ledger are public, any blockchain node can repeat this process to verify the authenticity of the results without the need for a third party, thus ensuring the convenience of resource computation.

[0063] The aforementioned resource processing method introduces an event ledger containing real resource processing information corresponding to at least one user business event targeting the target business. In response to a data query request initiated by a data requester for the target business, the event ledger corresponding to the target business is retrieved from the blockchain. Then, a resource processing smart contract is invoked to process the real resource processing information in the event ledger, obtaining the resource calculation result, which is then fed back to the data requester. Compared to related technologies that directly upload processed financial data to the blockchain, this method stores the real resource processing information corresponding to user business events in the blockchain. Upon detecting a data query request, the resource processing smart contract is invoked to process the real resource processing information and obtain the resource calculation result. This is equivalent to replaying the event chain of the target business and dynamically deriving the resource calculation result, ensuring the reliability of financial data acquisition.

[0064] Based on the above embodiments, in this application embodiment, when the event ledger contains at least two pieces of real resource processing information, an optional method for determining the resource calculation result is provided, such as... Figure 3 As shown, the specific steps include:

[0065] S301, Sort each piece of real resource processing information according to its generation timestamp to obtain the sorting result.

[0066] The so-called generation timestamp is used to characterize the generation time of the actual resource processing information. The so-called sorting result contains the actual resource processing information of each time series.

[0067] Optionally, the real resource processing information can be sorted according to the generation timestamps of each real resource processing information, in chronological order, to obtain the sorting result.

[0068] S302, based on the sorting results, invoke the resource processing smart contract to process each real resource processing information in sequence and obtain the resource calculation results.

[0069] Optionally, the calculation rules contained in the resource processing smart contract can be invoked to calculate each real resource processing information in the sorted result sequentially, thereby obtaining the resource calculation result. Alternatively, the calculation rules contained in the resource processing smart contract can be invoked based on the business description information of the target business to calculate each real resource processing information in the sorted result sequentially, thereby obtaining the resource calculation result.

[0070] In this embodiment of the application, by sorting the real resource processing information according to the generated timestamp, the rationality of target service retransmission during resource calculation can be guaranteed, thereby ensuring the accuracy of resource calculation results.

[0071] Based on the above embodiments, the method for determining the resource calculation result is further refined in this embodiment. Specifically, based on the data query request, the parameters to be processed in each real resource processing information are determined; based on the sorting result, the resource processing function in the resource processing smart contract is called to process the parameters to be processed in each real resource processing information in turn to obtain the resource calculation result.

[0072] The so-called parameters to be processed are the actual resource parameters that need to be involved in resource calculation. For example, this could be the actual repayment amount. The so-called resource processing function is the function used for resource processing; for example, it could be the calculation function corresponding to the calculation logic in the tax calculation rules.

[0073] Understandably, since real resource processing information contains various types of data, such as resource parameters, generation timestamps, and business action identifiers, in order to save computing resources, the parameters to be processed in each piece of real resource processing information can be determined based on the corresponding resource parameter identifier in the data query request before calculation.

[0074] For example, if the resource parameter is identified as a repayment resource identifier, the repayment resource identifier can be used as an index to query the actual resource processing information, obtain the repayment parameter in the actual resource processing information, and use the repayment parameter as a parameter to be processed.

[0075] Furthermore, after determining the parameters to be processed in each real resource processing information, the resource processing function in the resource processing smart contract can be called to calculate the parameters to be processed in each real resource processing information in the sorting result in turn, thereby obtaining the resource calculation result.

[0076] In this embodiment of the application, by first determining the parameters to be processed in the real resource processing information, and then calling the resource processing function to process the parameters to be processed in sequence, the resource calculation result can be obtained, which can reduce the computing power consumption in the calculation process and improve the efficiency of resource calculation.

[0077] Based on the above embodiments, this application provides an optional method for information acquisition, such as... Figure 4 As shown, the specific steps include:

[0078] S401, obtain a snapshot of the business status associated with the target business.

[0079] A business status snapshot is a snapshot that represents the resource processing status of a target business at a specific moment. To ensure computational efficiency, a business status snapshot can be saved at the corresponding moment in a preset snapshot generation cycle and stored in a preset snapshot cache. For example, the business status snapshot can be saved daily at 1 AM, then hashed, and the hash result stored on the blockchain.

[0080] Optionally, the latest business status snapshot associated with the target business can be obtained from the snapshot cache based on the business identifier in the data query request.

[0081] S402: Based on the snapshot generation time of the business status snapshot, retrieve the event ledger corresponding to the target business from the blockchain.

[0082] The snapshot generation time refers to the moment when a snapshot of the business state is generated. The actual resource processing information contained in the event ledger is the actual resource processing information generated after the snapshot generation time.

[0083] It is understandable that since the business status snapshot already contains the business status at a certain moment, there is no need to repeatedly obtain the actual resource processing information before the snapshot generation time. Instead, only the actual resource processing information after the snapshot generation time needs to be obtained.

[0084] Optionally, an event ledger containing real resource processing information generated by the target business after the snapshot generation time can be obtained from the blockchain based on the snapshot generation time of the business status snapshot.

[0085] In this embodiment of the application, a business status snapshot is introduced. By using the business status snapshot as a calculation benchmark, computing resources can be effectively saved and resource computing efficiency can be improved.

[0086] Based on the above embodiments, this application provides another optional method for determining resource calculation results. Specifically, it involves calling a resource processing smart contract to process the real resource processing information in the business state snapshot and event ledger to obtain the resource calculation results.

[0087] Optionally, before performing calculations, the parameters to be processed in each real resource processing information can be determined based on the resource parameter identifier corresponding to the data query request. Then, the resource processing function in the resource processing smart contract can be called to calculate the parameters to be processed in the real resource processing information sequentially based on the business state snapshot, thus obtaining the resource calculation result.

[0088] In this embodiment of the application, by processing the business status snapshot and the actual resource processing information generated after the business status snapshot is generated, the resource calculation result is obtained, which can improve the efficiency of resource calculation while ensuring the accuracy of the resource calculation result.

[0089] Based on the above embodiments, this application provides an optional method for updating smart contracts, specifically, in response to an update event for resource processing rules, updating the resource processing smart contract according to the resource processing logic in the update event.

[0090] Among them, the so-called resource processing rules are the calculation rules for resource processing, and the so-called resource processing logic is the calculation logic for resource processing.

[0091] Optionally, when there is a need to change resource processing rules, the rule management terminal corresponding to the resource processing rules can initiate an update event for the resource processing rules based on the updated resource processing logic corresponding to the resource processing rules.

[0092] Upon detecting an update event, the original resource processing logic in the resource processing smart contract can be updated based on the resource processing logic within the update event, resulting in an updated resource processing smart contract. At this point, the updated resource processing smart contract can be directly invoked to reprocess the actual resource processing information and obtain the resource calculation result. It is worth noting that no data migration or other operations are required during this process; simply recalculating the resources based on the updated resource processing smart contract is sufficient to obtain the resource calculation result.

[0093] Alternatively, based on the logical differences between the original resource processing logic in the resource processing smart contract and the resource processing logic in the update event, a target processing logic can be determined that can directly convert the resource calculation result based on the original resource processing logic into the resource calculation result based on the updated resource processing logic. Then, the target processing logic can be used as the resource calculation logic in the resource processing smart contract. At this point, the original resource calculation result can be directly updated using the target processing logic in the resource processing smart contract, resulting in a resource calculation result adapted to the changed resource processing rules.

[0094] In this embodiment of the application, by updating the resource processing smart contract, the real resource processing information stored in the blockchain can be recalculated using the updated resource processing smart contract to obtain resource calculation results that are compatible with the changed resource processing rules, thereby avoiding data migration and improving the efficiency of resource calculation.

[0095] Figure 5 This is a flowchart illustrating a resource processing method in another embodiment. Based on the above embodiments, this embodiment provides an optional example of a resource processing method. (In conjunction with...) Figure 5 The specific implementation process is as follows:

[0096] S501 responds to a data query request initiated by a data requester for a target business and retrieves the event ledger corresponding to the target business from the blockchain.

[0097] The event ledger contains real resource processing information corresponding to at least one user business event for the target business.

[0098] S502, based on the generation timestamp of each real resource processing information in the event ledger, sort the real resource processing information to obtain the sorting result.

[0099] S503, based on the data query request, determine the parameters to be processed in each real resource processing information.

[0100] S504: Based on the sorting results, the resource processing function in the resource processing smart contract is called to process the parameters to be processed in each real resource processing information in turn, and the resource calculation results are obtained.

[0101] Optionally, a snapshot of the business status associated with the target business can also be obtained; based on the snapshot generation time of the business status snapshot, the event ledger corresponding to the target business can be obtained from the blockchain; wherein, the actual resource processing information contained in the event ledger is the actual resource processing information generated after the snapshot generation time.

[0102] Furthermore, the resource processing smart contract is invoked to process the actual resource processing information in the business state snapshot and event ledger to obtain the resource calculation results.

[0103] Optionally, in response to an update event for resource processing rules, the resource processing smart contract is updated according to the resource processing logic in the update event.
