Further, referring to fig. 4, the present invention provides a second embodiment of a transaction platform system method based on a blockchain, based on the embodiment shown in fig. 3, based on that the electronic contract is a purchase-sale contract made by a buyer and a seller according to a preset rule before transaction initiation, the electronic contract has at least two transaction terminals, the transaction terminals are a buyer transaction terminal and a seller transaction terminal, for convenience of management, based on a secret principle, the blockchain is authorized in groups, and the transaction terminals in the same group are on the same blockchain branch chain. Each transaction terminal signing the electronic contract is on the same blockchain branch chain, and the step of determining each transaction terminal of a blockchain according to the electronic contract comprises the following steps:
step S21, determining the corresponding block chain branch chain according to the electronic contract;
and step S22, determining each transaction terminal according to the block chain branch chain.
The blockchain also includes group authorization, and transaction terminals of the same group are on the same blockchain branch chain. The grouping is set by preset rules of the electronic contract, such as: the electronic contract is made by a supplier and a core enterprise, but a logistics provider exists in the concrete implementation process, and it can be understood that the supplier and the core enterprise can set the logistics provider as the same group and participate and share all or part of transaction information in the electronic contract when making the electronic contract. The above list of one or more embodiments is only one of group authorization and is not intended to represent only such embodiments, and other embodiments similar to the present application are also within the scope of the present application.

In this embodiment, the blockchain further includes group authorization, where each transaction terminal that signs the electronic contract is on the same blockchain branched chain, and by determining the corresponding blockchain branched chain according to the electronic contract and then determining each transaction terminal according to the blockchain branched chain, transactions of transaction terminals in the same group are realized on the same blockchain branched chain, and transaction information can be shared controllably and limitedly without revealing business privacy.
Further, referring to fig. 5, the present invention provides a third embodiment of a transaction platform system method based on a blockchain, and based on the embodiment shown in fig. 3, when the transaction information type is a reconciliation request, the step of synchronously updating the transaction information with a transaction ledger corresponding to each transaction terminal of the blockchain includes:
step S31, comparing the reconciliation voucher of each transaction terminal of the block chain;
and step S32, determining the reconciliation voucher matching of each transaction terminal, and synchronously updating the reconciled information to the transaction ledger book reconciled by each transaction terminal.
When the account checking request is obtained, an electronic contract corresponding to the account checking request is determined, then each transaction terminal of the block chain is determined according to the electronic contract, and account checking certificates of each transaction terminal are obtained and compared. The reconciliation voucher can be transaction information recorded at each transaction terminal of the block chain, and can also be acquired through an electronic contract. For example: when the account checking request is obtained, determining an electronic contract corresponding to the account checking request, determining each transaction terminal of the block chain according to the electronic contract, comparing a delivery certificate recorded by a delivery terminal with a receiving certificate recorded by a receiving terminal, and when the delivery quantity in the delivery certificate is consistent with the receiving information in the receiving certificate, determining that the account checking certificates of each transaction terminal are matched. The above list of one or more embodiments for matching and determining a match of reconciliation documents is not intended to represent only this embodiment, and other embodiments similar to the present application are also within the scope of the present application.
It can be understood that after the comparison and matching, the checked information needs to be synchronously updated to the transaction ledger of the check of each transaction terminal. For example: and synchronously updating the account checked information to the delivery terminal and the vending terminal. The synchronization method is the same as the transaction information synchronization method, and is not described here.
In this embodiment, when the transaction information type is a reconciliation request, the transaction terminal and the transaction ledger book which need to be reconciled are determined, the recorded reconciliation certificates are extracted, the reconciliation certificates are compared, and after the reconciliation certificates of the transaction terminals are determined to be matched, the reconciled information is synchronously updated to the transaction ledger book reconciled by the transaction terminals. The account checking processing of the transaction information is realized, and the operation is simple, convenient and quick.
Further, referring to fig. 6, the fourth embodiment of the transaction platform system method based on the blockchain according to the present invention, based on the embodiment shown in fig. 5, after the step of determining that the reconciliation documents of the transaction terminals are matched and synchronously updating the reconciled information to the transaction ledger of the reconciliation of the transaction terminals, the method further includes:
step S33, acquiring the contract period of the electronic contract;
step S34, after the contract period is reached, a payment terminal and a collection terminal are determined, wherein each transaction terminal comprises the payment terminal and the collection terminal;
and step S35, transferring accounts payable agreed by the electronic contract from the account corresponding to the payment terminal to the account corresponding to the collection terminal.
And when the buyer and the seller formulate an electronic contract according to the preset rules, the contract deadline is determined at the same time, and the contract deadline is recorded in the transaction ledger of each transaction terminal. And after confirming that the reconciliation certificates of all transaction terminals are matched and synchronously updating the reconciled information to the transaction ledgers of all transaction terminals, acquiring the contract deadline by initiating an acquisition request.
It is understood that when the contract term is reached, i.e., the electronic contract expires, the payment terminal and the payment receiving terminal may be determined based on the electronic contract. The payment terminal is a buyer, and the collection terminal is a seller. For example: according to the delivery information, the collection terminal can be determined, namely the delivery terminal is the collection terminal. And obtaining the payment terminal according to the determined receiving terminal.
The transaction terminal also records bank information of the user, and the transaction platform can directly use the bank information to pay and collect money under the preset condition. For example: when the buyer and the seller make an electronic contract, the platform can automatically transfer accounts payable of the buyer account into the seller account according to the reserved bank information by appointing when the contract expires.
Therefore, in this embodiment, the electronic contract only contains one reconciliation transaction, which means that the transaction process of the electronic contract is completed by one delivery and receipt. Therefore, after the reconciliation voucher of each transaction terminal is determined to be matched, the transaction is finished. For example: the electronic contract is that a buyer purchases 100 tons of goods to a seller, the seller only sends 100 tons of goods, the buyer also receives 100 tons of goods, and the reconciliation step is completed. It is understood that when the reconciliation certificates of the transaction terminals are determined to be matched and the contract period is reached, the platform can automatically transfer accounts payable of the buyer account to the seller account according to the reserved bank information.
Optionally, after determining that the reconciliation certificates of the transaction terminals are matched and the reconciled information is synchronously updated to the transaction ledger of the reconciled transaction terminals, the receivable accounts can be obtained according to the electronic contract, then, invoice information is automatically generated according to the reconciliation information, the logistics information, the goods acceptance information, the fund information and the like, after the invoice information is generated, a preset invoicing program is called to automatically generate an electronic invoice, and after the electronic invoice and the invoice information are synchronously updated to the transaction ledger corresponding to each transaction terminal of the block chain, the step of obtaining the contract deadline of the electronic contract in this embodiment is executed.
In this embodiment, after the reconciliation information is synchronized to the transaction book of the reconciliation of each transaction terminal, the payment terminal and the collection terminal are determined after the contract expires by acquiring the contract term of the electronic contract, so that the accounts payable agreed by the electronic contract is transferred from the account corresponding to the payment terminal to the account corresponding to the collection terminal, the accounting is intelligently and conveniently urged, and the default risk of the enterprise is reduced.

step S311, sending transaction reminding information to the transaction terminal corresponding to the current transaction node.
After the contract period is reached, the condition that the transaction information agreed by the electronic contract is not finished is also existed. For example: the electronic contract is that a buyer purchases 100 tons of goods to a seller, the seller delivers goods for 4 times according to the contract, after the contract is expired, the seller only sends 75 tons of goods, the buyer only receives 75 tons of goods, and then the goods of 25 tons are not transacted, namely, the buyer and the seller complete 3 times of reconciliation, and one time of reconciliation is incomplete. The partial transaction message is the 25 ton item in the above example. Then when some of the transaction information remains unchecked, it is necessary to determine the current transaction node, i.e., whether 25 tons of items in the above example were not delivered at the shipping node or received at the receiving node. When it is determined that 25 tons of items in the above example are not delivered at the shipping node, a transaction reminder message is sent to the shipping terminal.
Optionally, when the transaction information agreed by the electronic contract is checked, the step of determining the payment terminal and the payment receiving terminal is performed. For example: the electronic contract is that a buyer purchases 100 tons of goods to a seller, the seller is specified to deliver goods for 4 times by the contract, after the contract is expired, the 4-time goods receiving and delivery of the buyer and the seller are checked, and then all transaction information appointed by the electronic contract is checked.
In this embodiment, after the contract expires, it is first determined whether each transaction information agreed by the electronic contract has been reconciled, and when each transaction information agreed by the electronic contract has been reconciled, the step of determining the payment terminal and the payment receiving terminal is performed; and when partial transaction information in each transaction information agreed by the electronic contract is not checked, determining a current transaction node, and then sending transaction reminding information to a transaction terminal corresponding to the current transaction node. If the transaction is not completed, the reminding operation is carried out on the responsible party, and the operation is intelligent.
The invention also provides a transaction platform system terminal based on the blockchain, which comprises a memory, a processor and a platform management program stored on the memory and capable of running on the processor, wherein when the platform management program is executed by the processor, the platform management program realizes the steps of the transaction platform system method based on the blockchain.
In addition, an embodiment of the present invention further provides a computer-readable storage medium, where a platform management program is stored on the computer-readable storage medium, and the platform management program, when executed by a processor, implements the steps of the above-mentioned transaction platform system method based on blockchain.
