Description

Technical Field

[0001] The present invention relates to the field of blockchain technology, and in particular to a real-time account reconciliation method and device, and electronic equipment based on blockchain. Background Art

[0002] In order to ensure data consistency, the current fund system chooses to conduct reconciliation at a fixed time: for example, the fixed time is selected at 15:00. After 15:00 every day, the transaction data is reconciled through file transfer and other methods, and adjustments are made when imbalances are found. However, due to the dependencies between the various systems, each system can only perform reconciliation operations within a centralized time. When the reconciliation finds that a transaction is abnormal, if the reconciliation and adjustment business personnel of the system are delayed in processing, the downstream system will also be delayed, resulting in problems such as delayed income distribution and delayed net value distribution. It can be seen that the reconciliation method in the prior art is not real-time and has low efficiency. Summary of the invention

[0066] Embodiment 2

[0067] See also Figure 2 , Figure 2Schematic diagram of a real-time reconciliation method based on blockchain disclosed in an embodiment of the present invention. Figure 2 The blockchain-based real-time reconciliation method may include the following steps:

[0068] 201. After a first participating node participating in a target transaction completes the transaction processing corresponding to the node, first transaction data is generated. The first participating node is a network node in the blockchain network.

[0069] In the embodiment of the present invention, for a certain target transaction, multiple participating nodes jointly participate, and each participating node completes its corresponding transaction processing and generates transaction data corresponding to its own transaction processing. For example, if the participating nodes include a seller, a share registration system, and a fund system, then after the seller participates in a certain target transaction and completes the transaction processing corresponding to the node, the generated transaction data may be "Subscription Fund 1, Subscription Shares X".

[0070] 202. Report the first transaction data to the blockchain network and broadcast it, so that any network node in the blockchain network except the first participating node can verify the target transaction according to the first transaction data.

[0071] In the embodiment of the present invention, all participating nodes participating in the target transaction will generate corresponding transaction data after completing the transaction processing corresponding to the node, and the corresponding transaction data generated by all participating nodes will be reported to the blockchain network and broadcast, so that any network node other than the first participating node in the blockchain network can verify the target transaction according to any transaction data. It can be understood that only when the target transaction is verified to be normal can the transaction data be uploaded to the public database maintained by the blockchain network.

[0072] 203. When any network node other than the first participating node verifies that the target transaction is abnormal according to the first transaction data, identify a second participating node participating in the target transaction, where the second participating node is the remaining node in the network node that participates in the target transaction except the first participating node.

[0073] In the embodiment of the present invention, the second participating node may be one network node or multiple network nodes, which is not limited in the present invention.

[0074] 204. Obtain second transaction data generated after the second participating node participates in the target transaction and completes the transaction processing corresponding to the node.

[0075] 205. Use the first transaction data and the second transaction data to perform reconciliation.

[0076] As an optional implementation, the first transaction data or the second transaction data may include target transaction information, which includes an identification code. Based on this, after executing step 204, the target transaction information in the second transaction data can be obtained, and the target transaction information includes an identification code; the reconciliation smart contract corresponding to the identification code is searched to trigger the reconciliation smart contract to perform a reconciliation operation. Accordingly, step 205 may include: determining whether the first attribute field of the target transaction exists in the first participating node and the second participating node; if so, determining all second attribute fields associated with the first attribute field in the first transaction data and the second transaction data; grouping all second attribute fields associated with the first attribute field to obtain multiple second attribute field sets of the same type; according to each second attribute field set, comparing the data corresponding to the second attribute field set in the first transaction data and the second transaction data.

[0077] By implementing this implementation mode, the reconciliation smart contract can be used to reconcile the first transaction data and the second transaction data, making the reconciliation method more intelligent.

[0078] visible, Figure 2 The described method can report the first transaction data generated by the first participating node participating in the target transaction after completing the transaction processing to the blockchain network and broadcast it. Any network node in the blockchain network can verify the target transaction in real time based on the first transaction data. When the target transaction is verified to be abnormal, the remaining participating nodes participating in the target transaction are identified, and the first transaction data is used to reconcile with the second transaction data generated by the remaining participating nodes. Reconciliation and adjustment can be performed in real time, thereby improving reconciliation efficiency.

[0079] Embodiment 3

[0080] See also Figure 3 , Figure 3 FIG. 1 is a flow chart of another real-time reconciliation method based on blockchain disclosed in an embodiment of the present invention. Figure 3 As shown, the real-time reconciliation method based on blockchain may include the following steps:

[0081] 301 to 304. Among them, steps 301 to 304 are the same as steps 201 to 204 described in the second embodiment, and will not be described in detail in this embodiment of the present invention.

[0082] As an optional implementation, after executing step 303, the following steps may be performed:

[0083] When any network node other than the first participating node verifies that the target transaction is abnormal according to the first transaction data, an alarm message is broadcast to the blockchain network to inform all network nodes on the blockchain network that the target transaction is abnormal. As another optional implementation, the above implementation can also be performed simultaneously with step 303.

[0084] By implementing this implementation method, timely alarms can be issued, and there is no need to wait until the designated time for centralized reconciliation to discover transaction anomalies, so that the entire transaction process can be monitored.

[0085] 305. Extract the corresponding public ledger within a preset time range from the public database maintained by the blockchain network.

[0086] In an embodiment of the present invention, when the target transaction is verified to be abnormal, the transaction data generated by all participating nodes after participating in the target transaction cannot be uploaded to the public database maintained by the blockchain network through verification. Therefore, extracting the corresponding public account book within the preset time range from the public database maintained by the blockchain network may include part of the transaction data of the target transaction, or may not include any transaction data of the target transaction, which is not limited by the present invention. Among them, the preset time range may be a period of time before the time node sent for the target transaction, and the corresponding public account book within the preset time range includes account book data associated with the transaction data of the target transaction.

[0087] 306. Verify whether the first transaction data is normal according to the public account book. If normal, execute step 307; if abnormal, execute step 308.

[0088] As an optional implementation, before executing step 306, the following steps may be performed: extracting all account book data related to the first participating node from the public account book within a preset time range; aggregating all account book data related to the first participating node to obtain a target account book centered on the first participating node. Accordingly, the specific method of executing step 306 may be to verify whether the first transaction data is normal based on the target account book.

[0089] The implementation of this embodiment can speed up the reconciliation process and provide a better understanding of the asset status of the first participating node.

[0090] In the embodiment of the present invention, the account data in the public account book that is associated with the transaction data is used to verify whether the transaction data is normal. For example, if the participating node is the payer, the transaction data of the payer is "transfer amount X", and before this transaction, the account data recorded by the payer in the public database maintained by the blockchain network is "total assets Y", and Y is less than X, then the transaction data is determined to be abnormal.

[0091] 307. Use the first transaction data as the benchmark data and use the benchmark data to reconcile with the second transaction data.

[0092] In the embodiment of the present invention, if the first transaction data is normal, the first transaction data is used as the reference data to reconcile with the second transaction data. For example, assuming that the first transaction data includes "amount X transferred to the second participating node" and the second transaction data includes "amount Y transferred from the first participating node", if X=Y, the second transaction data is normal; otherwise, the second transaction data is abnormal.

[0093] 308. Issue a reminder message to remind the business personnel corresponding to the first participating node to perform manual reconciliation, and remind the business personnel corresponding to the first participating node to adjust the first transaction data.

[0094] 309. Receive feedback information fed back by the business personnel through the first participating node, where the feedback information is used to indicate that the first transaction data is adjusted to the target first transaction data, and the target first transaction data is normal.

[0095] 310. Use the target first transaction data as the benchmark data and use the benchmark data to reconcile with the second transaction data.

[0096] It can be seen that the implementation Figure 3 The described method can not only perform reconciliation and adjustment in real time to improve reconciliation efficiency, but also issue timely alarms, eliminating the need to wait until a designated time for centralized reconciliation to discover transaction anomalies, thereby enabling monitoring of the entire transaction process.

[0097] In addition, the reconciliation process can be accelerated and the asset status of the first participating node can be better understood.

[0098] Embodiment 4

[0099] See also Figure 4 , Figure 4 This is a flowchart of another real-time reconciliation method based on blockchain disclosed in an embodiment of the present invention. Figure 4 The blockchain-based real-time reconciliation method may include the following steps:

[0100] 401 to 409. Among them, steps 401 to 409 are the same as steps 301 to 309 described in the third embodiment, and will not be described in detail in this embodiment of the present invention.

[0101] 410. Taking the target first transaction data as the reference data, determine whether the reference data matches the second transaction data. If they do not match, execute step 411; if they match, end this process.

[0102] In the embodiment of the present invention, as an optional implementation, step 410 may include the following steps:

[0103] The target first transaction data is used as the benchmark data;

[0104] Determining whether a first sum of the plurality of transaction detail data included in the reference data matches a second sum of the plurality of transaction detail data included in the second transaction data;

[0105] If the first sum does not match the second sum, it is determined that the reference data does not match the second transaction data.

[0106] If the first sum matches the second sum, determining whether each transaction detail data included in the reference data matches the corresponding transaction detail data in the second transaction data;

[0107] If any transaction detail data included in the reference data does not match the corresponding transaction detail data in the second transaction data, it is determined that the reference data does not match the second transaction data.

[0108] The implementation of this embodiment can improve the accuracy of data judgment.

[0109] 411. Send a reminder message to the second participating node to remind the second participating node to adjust the second transaction data.

[0110] 412. When the second participating node receives the reminder message, the second transaction data is adjusted based on the benchmark data according to the account adjustment rules agreed upon in the smart contract of the second participating node.

[0111] In the embodiment of the present invention, as an optional implementation, after executing step 412, the following steps may be performed:

[0112] receiving a reconciliation completion message fed back by the second participating node, where the reconciliation completion message is used to indicate that the second transaction data is adjusted to the target second transaction data, and the target second transaction data is normal;

[0113] The benchmark data and the target second transaction data are uploaded to a public database.

[0114] As an optional implementation, before uploading the benchmark data and the target second transaction data to the public database, the following steps may be performed:

[0115] Determine whether the baseline data and the target second transaction data need to be processed for privacy protection; if so, generate a key for the plaintext encryption algorithm, and use the plaintext encryption algorithm using the key to encrypt the baseline data and the target second transaction data respectively to generate encrypted baseline data and target second transaction data; encrypt the key using an agreed rule to generate a key ciphertext, and the agreed rule includes an algorithm that enables the first participating node and the second participating node to encrypt and decrypt the key ciphertext in a preset manner; upload the encrypted baseline data and target second transaction data to a public database.

[0116] By implementing this implementation method, all transaction data for a certain target transaction can be encrypted, and only the participating nodes participating in the target transaction can decrypt and view it, so the privacy of special transaction data can be protected.

[0117] It can be seen that the implementation Figure 4 The described method can not only perform real-time reconciliation and adjustment, improve reconciliation efficiency, but also improve the accuracy of data judgment. In addition, the privacy of special transaction data can be protected.

Figure 5 As shown, the real-time reconciliation system based on blockchain may include: a generation unit 501, a broadcast unit 502, an identification unit 503, an acquisition unit 504 and a reconciliation unit 505, wherein:

[0120] A generating unit 501 is used to generate first transaction data after a first participating node participating in a target transaction completes a transaction processing corresponding to the node, where the first participating node is a network node in the blockchain network;

[0121] A broadcast unit 502 is used to report the first transaction data to the blockchain network and broadcast it, so that any network node other than the first participating node in the blockchain network verifies the target transaction according to the first transaction data;

[0122] The identification unit 503 is used to identify a second participating node participating in the target transaction when any network node other than the first participating node verifies that the target transaction is abnormal according to the first transaction data, where the second participating node is a node in the network node other than the first participating node participating in the target transaction;

[0133] By implementing this implementation mode, the reconciliation smart contract can be used to reconcile the first transaction data and the second transaction data, making the reconciliation method more intelligent.

[0134] visible, Figure 5 The blockchain-based real-time reconciliation system shown can report the first transaction data generated after the first participating node participating in the target transaction completes the transaction processing to the blockchain network and broadcast it. Any network node in the blockchain network can verify the target transaction in real time based on the first transaction data. When the target transaction is verified to be abnormal, the remaining participating nodes participating in the target transaction are identified, and the first transaction data is used to reconcile with the second transaction data generated by the remaining participating nodes.
