Description

Background Art

[0002] Transaction matching refers to a transaction method in which the seller entrusts a sales order / sales response order in the trading market, and the buyer entrusts a purchase order / purchase response order in the trading market. The trading market determines the transaction price of both parties based on the principle of price priority and time priority, and generates an electronic transaction contract.

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the technical solution of the present application, rather than all of the embodiments. Based on the embodiments recorded in the application documents, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the technical solution of the present application.

[0043] The following is a brief introduction to the design concept of the embodiment of the present application:

[0044] Transaction matching refers to a transaction method in which the seller entrusts a sales order / sales response order in the trading market, and the buyer entrusts a purchase order / purchase response order in the trading market. The trading market determines the transaction price of both parties based on the principle of price priority and time priority, and generates an electronic transaction contract.

[0045] Transaction matching has the advantages of efficiency, fairness and transparency. However, manual transaction matching is easily affected by subjective factors such as the operator's personal experience, knowledge level, and information processing ability. There is a lack of strict standardized processes, and the decision-making criteria between different operators may differ, resulting in poor consistency and stability in transaction matching results, and may miss better trading opportunities. This not only increases operational risks, but also reduces the overall efficiency of the system.

[0046] In view of this, the embodiments of the present application provide a transaction matching method, device, equipment and storage medium. The method includes: through a smart contract, matching the purchase order of the product purchaser and the supply products of multiple original suppliers to obtain a transaction matching result; then synchronizing the transaction matching result to multiple blockchain nodes, and after node verification and node consensus, putting the block storing the transaction matching result on the chain.

[0047] This application calls smart contracts to fairly and reasonably arrange and match orders placed by product purchasers, ensure the consistency and stability of transaction matching results, and achieve high throughput, low latency response, low fault tolerance, strong scalability and load balancing of the transaction matching system.

[0048] The preferred embodiments of the present application are described below in conjunction with the drawings in the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In addition, the embodiments and features in the embodiments of the present application may be combined with each other if there is no conflict.

[0049] The present application embodiment provides a transaction matching system based on blockchain, the core functional modules of which are as follows: Figure 1 As shown, it includes the core system management module, product release information query module, transaction management module, transaction matching engine, matching behavior audit module, transaction fund settlement module and trader order module.

[0050] Before executing transaction matching, the core system management module calls the unified identity authentication system to verify the authority of the product purchaser and the original supplier. After the verification is passed, the product purchaser and the original supplier are allowed to log in to the transaction matching system, publish purchase orders and product supply information in the system, and view the purchase order and transaction matching processing progress.

[0051] When executing transaction matching, the transaction matching engine calls the smart contract of the blockchain, and integrates the purchase order of the product purchaser with the product supply information of multiple original suppliers into transaction matching data through the smart contract, matches the product purchaser with a suitable supplier, and completes the transaction matching.

[0052] After the transaction matching is completed, the transaction management module generates the transaction matching result, digitally signs the transaction matching result, and uploads the signed transaction matching result to the blockchain node for storage. Furthermore, the transaction compliance audit module can also be used to audit the transaction compliance of each completed transaction.

[0053] Product purchasers can view the order details and transaction matching progress of each purchase order through the product release information query module. The transaction matching progress includes any of the following: unprocessed, being processed, and completed.

[0054] The transaction matching system adopts an authoritative real-name authentication model for individuals and enterprises to ensure that the signatories of the electronic contract have legal identities and guarantee the legitimacy of the prerequisites for signing the contract. Therefore, the product purchaser can place orders with the target supplier selected by the smart contract through the trader order module, generate an electronic transaction contract, and pay the corresponding funds to the target supplier through the transaction fund settlement module.

[0055] Combination Figure 2A-2B The schematic diagram shown shows that the specific process of transaction matching using the method provided in the embodiment of the present application is as follows:

[0056] S201: Through smart contracts, the purchase order of the product purchaser and the supply products of multiple original suppliers are matched to obtain the transaction matching results.

[0057] Before executing transaction matching, the core system management module calls the unified identity authentication system to verify the authority of the product purchaser and the original supplier. The product purchaser and the original supplier log in to the supply chain unified identity authentication system respectively to verify whether they have the login authority to the enterprise transaction matching system. After passing the authority verification, they log in to the enterprise transaction matching system respectively.

[0058] The product purchaser generates a purchase order in the enterprise transaction matching system and uploads the purchase order to the smart contract of the blockchain. In addition, the original supplier records the specific product information of the supplied products in the enterprise transaction matching system, generates their own product supply information, and uploads each product information to the smart contract of the blockchain.

[0059] When executing transaction matching, the transaction matching engine calls the smart contract of the blockchain, and matches the purchase order with the product supply information of multiple original suppliers stored in the blockchain through the smart contract.

[0060] The purchase order includes the product to be purchased, the transaction quantity, and the expected price, and the product supply information includes the supplied product, supply quantity, and supply price. Through smart contracts, the purchase order of the product purchaser is matched with the product supply information of multiple original suppliers to obtain candidate suppliers that support the supply of the purchased product in the purchase quantity.

[0061] Then, through smart contracts, the supplied products of multiple candidate suppliers are evaluated to obtain the corresponding product evaluation values, and the candidate supplier with the highest product evaluation value is selected as the target supplier for the product purchaser.

[0062] When a candidate supplier has not supplied products to any product purchaser before, the supply product is evaluated through the smart contract based on the sales volume, price, and supply capacity of the candidate supplier to obtain the product evaluation value of the supply product;

[0063] When a candidate supplier has previously supplied products to at least one product purchaser, the supplied products are evaluated through a smart contract based on the candidate supplier's historical purchase value and supplier credit value to obtain a product evaluation value of the supplied products.

[0064] S202: Synchronize the transaction matching results to multiple blockchain nodes. After passing the node verification and node consensus, the block storing the transaction matching results is put on the chain.

[0065] Based on the purchase order and the selected target supplier, the smart contract generates the corresponding transaction matching results, and writes the transaction matching results into the blockchain node, using the immutability of the blockchain to ensure the accuracy and traceability of the data and realize the tracking and recording of the entire transaction process. Among them, the transaction matching results include: transaction products, transaction quantity, transaction price, and the identity information of both parties to the transaction.

[0066] The product release information query module generates a purchase order in response to the order generation operation triggered by the product purchaser, and also displays each purchase order and the transaction matching processing progress of the purchase order in response to the order viewing operation triggered by the product purchaser. The transaction matching processing progress includes any of the following: unprocessed, being processed, and completed.

[0067] The transaction matching system adopts an authoritative real-name authentication model for individuals and enterprises to ensure that the signatories of the electronic contract have legal identities and guarantee the legitimacy of the prerequisites for signing the contract. Therefore, the product purchaser can place orders with the target supplier selected by the smart contract through the trader order module, generate an electronic transaction contract, and pay the corresponding funds to the target supplier through the transaction fund settlement module.
