This embodiment is applied to a blockchain, which can specifically include private chains, public chains, and alliance chains. The blockchain includes two or more nodes (here "above" includes the number, the same below). In this embodiment It is not particularly limited.

Before conducting transactions, build a blockchain trading platform. The blockchain trading platform includes multiple transaction terminals. The multiple transaction terminals may include suppliers, core enterprises, logistics providers, distributors, customs, and taxation. Wait two or more. Through the blockchain transaction platform, each transaction terminal can perform data transmission with the transaction platform system. The trading platform can synchronously update the data of the platform to each trading terminal for storage. Each transaction terminal performs transaction processing and information management, and records multiple different transaction ledgers, and different transaction information corresponds to different transaction ledgers.

Specifically, transaction information includes, but is not limited to, order information, shipping information, product information, transportation information, payment information, and the like. The transaction information can be obtained by manual input. For example, when the seller delivers the goods, the seller can check the goods to be shipped in the electronic contract on the transaction platform to obtain the shipping information or product information. The seller can also scan the QR code of the goods to be shipped to obtain product information or shipping information. For another example: when the seller receives a reconciliation request for accounts receivable, the seller can click Confirm to obtain the confirmation information. The method of obtaining the transaction information can also be obtained through an operation request inside the trading platform, for example: after the expiration of the electronic contract, a payment program is triggered, and the trading platform obtains the payment request.

It is understandable that each transaction information has a corresponding contract number or company attribute, company name, code number, etc., and the electronic contract to which the transaction information belongs can be determined according to the contract number or company attribute, company name, code number, etc. The electronic contract is a purchase and sale contract formulated by the buyer and the seller according to preset rules before the transaction is initiated, and is signed on the transaction platform based on the smart contract function. The smart contract can automatically execute the agreement that requires manual tasks to be completed and can Reduce manual intervention during the implementation of the agreement. For example, buyers and sellers sign electronic contracts based on smart contracts on the trading platform. The electronic contracts may include: transaction items, transaction periods, payment methods, contract sharers, etc. Based on smart contracts, the electronic contracts can be Real transaction records automatically complete transaction steps such as reconciliation and payment. For another example: after acquiring the transaction information, extract the contract number in the transaction information, and query the corresponding electronic contract according to the contract number.

It is understandable that the electronic contract is a purchase and sale contract formulated by the buyer and the seller according to preset rules before the transaction is initiated. The electronic contract has at least two transaction terminals, and transaction processing and information management are performed at the transaction terminals. The terminals are a buyer's transaction terminal and a seller's transaction terminal, and all transaction information of the electronic contract is recorded in each of them. Each transaction terminal has more than two transaction ledgers, and the transaction ledgers respectively record different transaction information of the electronic contract, that is, all transaction ledgers in the transaction terminal add up to the complete transaction information of the electronic contract . For example: when obtaining the shipping information, the shipping information is updated synchronously to the shipping account books of the buyer terminal and the seller terminal. For another example: after obtaining the reconciliation confirmation, the reconciliation confirmation is updated synchronously to the reconciliation book of the buyer terminal and the seller terminal.

Specifically, before the transaction information is synchronized to the transaction ledger corresponding to the transaction information type of each transaction terminal of the blockchain, the transaction information type is determined according to the transaction information, and the transaction information type includes transaction At least one of contract and logistics contract signing, delivery, receipt, logistics processing and information, import and export methods, customs clearance requests and customs information, invoice requests and invoicing, tax management requests, fund receipts and payments, and reconciliation requests. Optionally, the transaction may be divided into domestic trade and import and export trade. Specifically, the transaction information types of the domestic trade include: sales and purchase contracts, logistics contracts, receipts, shipments, logistics information, warehousing management, reconciliation requests, invoices, confirmation of accounts receivable and payable, receipts, payments, funds Mobility, taxation, etc. The transaction information types of the import and export trade include: sales and purchase contracts, import and export methods (general trade, processing with imported materials, transfer to factories), customs filing procedures, logistics contracts, logistics information, warehousing management (general trade and bonded logistics are managed differently ), reconciliation request, invoice, accounts receivable and payable confirmation, collection, payment, foreign exchange processing, tax processing, etc.

In this embodiment, after obtaining the transaction information, the transaction platform first determines the corresponding electronic contract according to the transaction information, and then determines each transaction terminal of the blockchain according to the electronic contract, and finally synchronously updates the transaction information to In the transaction ledger corresponding to each transaction terminal of the blockchain. The digital trading platform based on blockchain technology securely records the real trade background information of each participant in the trading platform, so that after obtaining the transaction information, the transaction information is updated to the transaction ledger of each terminal on the blockchain simultaneously. Accurately record and save the transaction information, make the transaction information true and transparent, can not be tampered with, and improve the reliability and security of the system.

Further, referring to Fig. 4, this application provides a second embodiment of a blockchain-based transaction platform system method. Based on the embodiment shown in Fig. 3 above, based on the above electronic contract, the buyer and seller follow the preset rules before the transaction is initiated. The established purchase and sale contract, the electronic contract has at least two transaction terminals, the transaction terminals are the buyer’s transaction terminal and the seller’s transaction terminal. For ease of management, based on the principle of confidentiality, the blockchain is authorized by groups, and the transaction terminals in the same group On the same blockchain branch. Each transaction terminal that signs the electronic contract is on the same blockchain branch, and the step of determining each transaction terminal of the blockchain according to the electronic contract includes:

Step S21: Determine the corresponding blockchain branch according to the electronic contract;

Step S22: Determine each transaction terminal according to the blockchain branch.

The blockchain also includes group authorization, and transaction terminals of the same group are on the same branch chain of the blockchain. The grouping is set by the preset rules of the electronic contract. For example, the electronic contract is formulated by the supplier and the core enterprise, but there are logistics providers in the specific implementation process. It is understandable that the supplier and the core enterprise When formulating an electronic contract, the logistics providers can be set to the same group to participate in and share all or part of the transaction information in the electronic contract. The foregoing list is only one or more embodiments in the group authorization, and does not represent only this embodiment, and other embodiments similar to the present application also belong to the protection scope of the present application.

It is understandable that the electronic contract authorized by the group is recorded in the blockchain branch, and the branch only records the unique electronic contract, which ensures that the participants of the electronic contract can share or verify the electronic contract Transaction information within a preset range.

In this embodiment, the block chain also includes group authorization, wherein each transaction terminal that signs the electronic contract is on the same block chain branch, and the corresponding block chain branch is first determined according to the electronic contract. Then, each transaction terminal is determined according to the blockchain branch chain, so that the transaction terminals of the same group can trade on the same blockchain branch chain, and the transaction information can be controlled and limitedly shared without leaking business privacy.

Further, referring to Fig. 5, the present application provides a third embodiment of a blockchain-based transaction platform system method. Based on the embodiment shown in Fig. 3 above, when the transaction information type is an account reconciliation request, the The step of synchronously updating the transaction ledger corresponding to each transaction terminal of the blockchain with transaction information includes:

Step S31, comparing the reconciliation vouchers of each transaction terminal of the blockchain;

Step S32: It is determined that the reconciliation vouchers of each transaction terminal match, and the reconciled information is updated synchronously to the transaction ledger reconciled by each transaction terminal.

When the reconciliation request is obtained, the electronic contract corresponding to the reconciliation request is determined first, and then each transaction terminal of the blockchain is determined according to the electronic contract, and the reconciliation certificate of each transaction terminal is obtained for comparison. The reconciliation voucher may be transaction information recorded in each transaction terminal of the blockchain, or it may be obtained through an electronic contract. For example: when obtaining a reconciliation request, determine the electronic contract corresponding to the reconciliation request, and then determine each transaction terminal of the blockchain according to the electronic contract, and combine the shipping certificate recorded by the shipping terminal with the receipt recorded by the receiving terminal. When the delivery voucher is compared, and the delivery quantity in the delivery voucher is consistent with the receipt information in the delivery voucher, it can be determined that the reconciliation voucher of each transaction terminal matches. The foregoing list is only one or more embodiments for comparing the reconciliation vouchers and determining the matching of the reconciliation vouchers, and does not represent only this embodiment. Other embodiments similar to this application also belong to the protection scope of this application.

It is understandable that, after the comparison and matching, the reconciled information needs to be updated synchronously to the transaction account reconciled by each transaction terminal. For example: Synchronously update the reconciled information to the shipping terminal and the vending terminal. The synchronization method is the same as the synchronization method of transaction information, and will not be described here.

In this embodiment, when the transaction information type is a reconciliation request, first determine the transaction terminal and the transaction account book that need to be reconciled, and then extract the recorded reconciliation voucher, and then compare the reconciliation voucher to determine the After the reconciliation vouchers of each transaction terminal are matched, the reconciled information is synchronously updated to the transaction account book of each transaction terminal. Realize the reconciliation processing of transaction information, the operation is simple and fast.

Further, referring to FIG. 6, the present application provides a fourth embodiment of a blockchain-based transaction platform system method. Based on the embodiment shown in FIG. 5, the determining that the reconciliation vouchers of each transaction terminal match, After the step of synchronously updating the reconciled information to the transaction account book of each transaction terminal, it also includes:

Step S33, obtaining the contract period of the electronic contract;

Step S34, after the expiration of the contract period, determine the payment terminal and the payment terminal, and each transaction terminal includes the payment terminal and the payment terminal;

Step S35: Transfer the accounts payable agreed in the electronic contract from the account corresponding to the payment terminal to the account corresponding to the payment terminal.

When the buyer and the seller formulate the electronic contract according to the preset rules, the contract period is also determined at the same time, and the contract period is recorded in the transaction account book of each transaction terminal. After it is determined that the reconciliation vouchers of each transaction terminal match, and the reconciled information is synchronously updated to the transaction account book of each transaction terminal, the acquisition request is initiated to obtain the contract period.

It is understandable that when the contract period arrives, that is, when the electronic contract expires, the payment terminal and the payment terminal can be determined according to the electronic contract. The payment terminal is a buyer, and the payment terminal is a seller. For example, the payment terminal can be determined according to the shipping information, that is, the shipping terminal is the payment terminal. According to the confirmation of the receiving terminal, the payment terminal can be obtained.

The transaction terminal also records the bank information of the user to which it belongs. Under preset conditions, the transaction platform can directly use the bank information for payment and collection. For example, when the buyer and seller formulate an electronic contract, they agree that when the contract expires, the platform can automatically transfer the accounts payable from the buyer's account to the seller's account based on the reserved bank information.

Therefore, in this embodiment, the electronic contract only includes one reconciliation transaction, which means that the transaction process of the electronic contract is completed in one delivery and delivery. Therefore, after it is determined that the reconciliation vouchers of the various transaction terminals match, it means that the transaction is completed. For example, the electronic contract is that the buyer purchases 100 tons of goods from the seller, and when the seller only sends out 100 tons of goods, the buyer also receives 100 tons of goods and completes the reconciliation step. It is understandable that when it is determined that the reconciliation vouchers of the various transaction terminals match and the contract period is reached, the platform can automatically transfer the accounts payable of the buyer's account to the seller's account according to the reserved bank information.

Optionally, after determining that the reconciliation vouchers of each transaction terminal match, and synchronously updating the reconciled information to the transaction ledger reconciled by each transaction terminal, the receivables may be obtained according to the electronic contract. Accounts, and then automatically generate invoice information based on the reconciliation information, logistics information, goods acceptance information, capital information, etc. After the invoice information is generated, the preset invoicing program is called to automatically generate the electronic invoice, and the electronic invoice and the invoice are automatically generated. After the information is synchronized to update the transaction ledger corresponding to each transaction terminal of the blockchain, the step of obtaining the contract period of the electronic contract described in this embodiment is performed.

In this embodiment, after the reconciliation information is synchronized to the transaction ledger reconciled by each transaction terminal, the contract period of the electronic contract is acquired first, and the payment terminal and the payment terminal are determined after the contract expires, It is realized that the accounts payable agreed in the electronic contract are transferred from the account corresponding to the payment terminal to the account corresponding to the payment terminal, which is intelligent and convenient in dunning and reduces the risk of default by the enterprise.

Further, referring to FIG. 7, the present application provides a fifth embodiment of a blockchain-based trading platform system method. Based on the embodiment shown in FIG. 6, the steps of the blockchain-based trading platform system method include :

Step S37, obtaining accounts payable and accounts receivable agreed in the electronic contract;

Step S38, sending the confirmation information of the accounts payable to the payment terminal, and sending the confirmation information of the accounts receivable to the receiving terminal;

Step S35, after receiving the response information of the payment terminal and the payment terminal, execute the transfer of the payment receivable from the account corresponding to the payment terminal to the account corresponding to the payment terminal.

Accounts payable and accounts receivable are the transaction amount recorded by the electronic contract, and the transaction amount can be obtained directly by the electronic contract, or can be obtained from the transaction account book where the reconciliation information is recorded in the transaction terminal. According to the transaction amount, the confirmation information of the accounts payable is sent to the payment terminal, and the confirmation information of the accounts receivable is sent to the receiving terminal. Only after both the payment terminal and the payment terminal make a determination operation, the payment operation can be triggered, and the platform system can transfer the payment receivable from the account corresponding to the payment terminal to the account corresponding to the payment terminal.

In this embodiment, by obtaining the accounts payable and accounts receivable agreed in the electronic contract, sending the confirmation information of the accounts payable to the payment terminal, and then sending the accounts receivable to the receiving terminal After receiving the response information of the payment terminal and the payment terminal, execute the transfer of the payment receivable from the account corresponding to the payment terminal to the account corresponding to the payment terminal , To realize the intelligent payment of electronic contracts, simplify the operation, and reduce the enterprise's risk of arrears.

Further, referring to FIG. 8, the present application provides a sixth embodiment of a blockchain-based trading platform system method. Based on the embodiment shown in FIG. 6, the steps of the blockchain-based trading platform system method include :

Step S39, after the expiration of the contract period, determine whether each transaction information agreed in the electronic contract has been reconciled;

Step S34, when each transaction information agreed in the electronic contract has been reconciled, execute the step of determining the payment terminal and the payment terminal;

Step S310, in each transaction information agreed in the electronic contract, when part of the transaction information is not reconciled, determine the current transaction node;

Step S311: Send transaction reminder information to the transaction terminal corresponding to the current transaction node.

After the expiration of the contract period, there is still the transaction information agreed in the electronic contract that has not been reconciled. For example: the electronic contract is that the buyer buys 100 tons of goods from the seller, and the contract stipulates that the seller will deliver the goods in 4 times. After the contract expires, the seller only sends out 75 tons of goods, and the buyer only receives 75 tons of goods. There are still 25 tons of items that have not been completed, that is, the buyer and the seller have completed 3 reconciliations, and one reconciliation is not completed. The part of the transaction information is the 25-ton item in the above example. When there is still part of the transaction information that has not been reconciled, the current transaction node needs to be determined, that is, whether the 25-ton item in the above example has not been sent out at the shipping node or has not been received at the receiving node. When it is determined that the 25-ton item in the above example is not sent out at the shipping node, a transaction reminder message is sent to the shipping terminal.

Optionally, when all transaction information agreed in the electronic contract has been reconciled, the step of determining the payment terminal and the payment terminal is executed. For example: the electronic contract is that the buyer purchases 100 tons of goods from the seller, and the contract stipulates that the seller will deliver the goods in 4 installments. After the contract expires, the 4 receipts and deliveries of the buyer and seller have been reconciled, which represents the electronic contract All agreed transaction information has been reconciled.

In this embodiment, after the contract expires, it is first determined whether each transaction information agreed in the electronic contract has been reconciled, and when the transaction information agreed in the electronic contract has been reconciled, the payment terminal is determined And the steps of the payment terminal; in each transaction information agreed in the electronic contract, when part of the transaction information is not reconciled, the current transaction node is determined first, and then the transaction reminder information is sent to the transaction terminal corresponding to the current transaction node.
