Description

Technical Field

[0001] The present invention relates to the field of blockchain technology, and in particular to an intelligent analysis system based on blockchain. Background Art

[0002] The supply chain is a network structure that connects the upstream and downstream, and flows goods from the production end to the consumer. It connects the enterprises in each link of the supply chain process, improves the coordination efficiency between enterprises, and maximizes the economic benefits of enterprises. A complete supply chain includes at least the following types of participants: raw material suppliers, transporters, commodity manufacturers, retailers and final consumers. The efficient operation of the supply chain is an important guarantee for economic development. As the number of various enterprises from raw materials to final consumers continues to increase, the production process of commodities has become more complicated. Moreover, with the development of economic globalization and the continuous expansion of the consumer market, various enterprises are constantly expanding their product production scale, which seriously affects the traceability analysis and processing. Therefore, it is necessary to design an intelligent analysis system based on blockchain with high intelligent control analysis and processing efficiency. Summary of the invention

The random value is further verified and signed to complete the corresponding consensus node election.

[0005] According to the above technical solution, the consensus management and data storage of the blockchain analysis system includes: After the election is completed, the blockchain enters the consensus stage, controlling the set of accounting nodes to package the transactions in the blockchain in turn. When the accounting node receives a transaction request, it verifies the legitimacy of its signature and transaction address. If the verification is successful, it is added to the transaction body of the current block. If the verification fails, the transaction request is directly rejected. The blockchain analysis system performs on-chain data storage management. The signature value of the upstream enterprise is verified by using a hash algorithm to calculate the hash value of the current enterprise's plaintext data. When calculating the hash value of the data, the hash value of the upstream enterprise will be included, so that the traceability data of a product stored in the database forms a chain structure.

Then, the contract address where the on-chain data is saved is stored in the corresponding off-chain data to complete the expanded storage.

[0007] According to the above technical solution, the optimization analysis process of the blockchain analysis system further includes: Further optimize the design and processing of the database table of the blockchain analysis system, so that each enterprise first registers information, including the blockchain address of the enterprise to which the enterprise belongs, the identity of the enterprise, the raw material production enterprise, the transportation enterprise, the commodity production enterprise and the commodity sales enterprise, and store consumer data information in a separate database; After setting the finishFlag flag, when the item is handed over to the downstream enterprise, the enterprise needs to call the setComplete function to change the flag status. The hash value and signature value can no longer be changed.

[0014] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. Together with the embodiments of the present invention, they are used to explain the present invention and do not constitute a limitation of the present invention. In the accompanying drawings: Figure 1 This is a flowchart of a blockchain-based intelligent analysis method provided in Example 1 of the present invention; Figure 2 This is a module structure diagram of a blockchain-based intelligent analysis system provided in Example 2 of the present invention. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] Embodiment 1: Figure 1 This is a flowchart of a blockchain-based intelligent analysis method provided in Embodiment 1 of the present invention. This embodiment can be applied to a blockchain analysis system. The method can be executed by a blockchain-based intelligent analysis system provided in an embodiment of the present invention. The system is composed of multiple software and hardware modules, such as Figure 1 As shown, the method specifically comprises the following steps: S101. Perform node selection management for the blockchain analysis system; Exemplarily, in an embodiment of the present invention, when a proof-of-work request is broadcast on a blockchain network, the control request includes a hash value of a parent block in a block header verified by a candidate node, wherein the value is the hash value of the latest block at the current moment and a random number, and the random value is further verified and signed to complete the corresponding consensus node election; in this step, after receiving the proof-of-work request, the candidate node in the network verifies the random value according to the above-mentioned proof-of-work principle, and when a random number that meets the difficulty value is verified, the candidate node sends a verification success message to the blockchain, and the message includes a verification success block header, and the verification success node will sign the information. When the system receives the verification success message and verifies successfully, it broadcasts a stop verification message to other nodes in the network, and the message includes the address information of the consensus node in this round. After receiving the message, other candidate nodes in the network stop the proof of work in this round, and the consensus node election in this round ends. Through this step, it can be ensured that more candidate nodes have the possibility of becoming consensus nodes, making the node selection of the blockchain analysis system more comprehensive, and making the node selection more efficient and accurate.

[0017] S102. Perform consensus management and data storage on the blockchain analysis system; Exemplarily, in an embodiment of the present invention, after the election is completed, the blockchain enters the consensus stage, and the control accounting node set takes turns to package the transactions in the blockchain. When the accounting node receives the transaction request, it verifies the legitimacy information of its signature and transaction address. If the verification is successful, it is added to the transaction body of the current block. If the verification fails, its transaction request is directly rejected; in this step, at the end of the current accounting node production cycle, the accounting node signs the block it generates and sends it to all nodes in the verification node set for verification. If the block cannot be generated normally during the production cycle, a node is selected from the candidate nodes to replace the current accounting node, and the accounting node replacement message is broadcast. The broadcast message contains the new accounting node information. When the verification node receives the block verification request, it verifies whether the block signature and each transaction in the transaction body are correct. If the verification is passed, a verification pass message is sent to the accounting node. If it is found that there are transactions in the block that are wrong, a verification failure message is sent to the accounting node. Through this step, the transaction delay of the blockchain analysis system is effectively reduced and the overall performance of the blockchain is improved.

[0018] The blockchain analysis system is used to store and manage on-chain data. The signature value of the upstream enterprise is verified by using a hash algorithm, and the hash value of the current enterprise's plaintext data is calculated. When calculating the hash value of the current data, the hash value of the upstream enterprise will be included, so that the traceability data of a product stored in the database forms a chain structure. In this step, when consumers verify the product, they only need to read the on-chain hash value and signature value of the last enterprise after obtaining the off-chain plaintext data to complete the verification, without having to obtain the on-chain data of all sub-enterprises. Therefore, this step can improve the traceability verification efficiency of the system.

[0019] S103, performing optimization analysis and processing of the blockchain analysis system; Illustratively, in an embodiment of the present invention, the off-chain data generated by each link of the commodity is processed, and the hash value and signature value results generated are stored in the blockchain by deploying a smart contract, and the enterprise public key is uploaded to the chain through the smart contract, and after the enterprise signature is successfully verified, the hash value and signature value are uploaded to the chain, and then the contract address where the on-chain data is saved is stored in the corresponding off-chain data to complete the expanded storage; through this step, all the data of the commodity from raw materials to sales can be obtained, which is used to trace the data of the commodity, effectively improving the operation and processing efficiency and accuracy of the blockchain analysis system.

[0020] The database table of the blockchain analysis system is further optimized and designed so that each enterprise first registers its information, including the blockchain address of the enterprise, the enterprise's identity, the raw material production enterprise, the transportation enterprise, the commodity production enterprise and the commodity sales enterprise, and stores consumer data information in a separate database; through this step, the efficiency of data information traceability processing can be effectively improved to avoid errors.

[0021] After setting the finishFlag flag, when the item is handed over to the downstream enterprise, the enterprise needs to call the setComplete function to change the flag status. After that, the hash value and signature value cannot be changed. When the downstream enterprise verifies the current enterprise data and its signature value, the finishFlag is false to avoid the same tag from being used again. In this step, before the item is delivered, in order to prevent the subsidiary from entering the wrong data due to negligence, the hash value and signature value can be modified through the update Value function, but only once. After the modification is completed, the modifyFlag flag needs to be set to true. The identificationCode represents the identification code of the downstream enterprise or consumer delivered by the current subsidiary. After the current subsidiary calls the setNextOwner function to set the identification code of its downstream enterprise or consumer, the downstream enterprise or consumer can obtain the hash value and signature value in the current contract. When the downstream enterprise receives the current subsidiary product, it first confirms the product status through the getFinishFlag function. If the product has been accepted, it rejects the product. If it has not been confirmed, it verifies its signature value. If the verification passes, the subsidiary to which the product belongs is notified to change the delivery status of the current product.

[0022] S104, performing interaction and feedback processing of the blockchain analysis system; Exemplarily, in the embodiment of the present invention, the query traceability analysis and display between the user and the system are enabled through interactive processing, which effectively improves the user's satisfaction; After the user uploads the usage opinion information of the blockchain analysis system, the feedback is transmitted to the workbench for management personnel to review and analyze.
