The block chain-based transaction payment method, the block chain-based transaction payment device, the block chain-based transaction payment computer equipment and the block chain-based transaction payment computer readable medium can effectively guarantee information security of a client during network transaction, are beneficial to standardizing transaction flow, and prevent behavior of a seller for manufacturing false orders, malicious orders and the like which disturb economic order of the market.

Example one
Referring to fig. 1, the present embodiment provides a transaction payment method based on a block chain, which specifically includes the following steps:
providing a blockchain network comprised of a plurality of nodes including a payor node, a payee node, and a manager node S1.
Blockchain technology, also known as distributed ledger technology, is a type of "accounting" that is commonly participated by several computing devices to collectively maintain a complete database. Since the blockchain technology has the characteristics of decentralization and transparency, each computing device can participate in database recording, and data synchronization can be rapidly performed among the computing devices, building a decentralization system by using the blockchain technology is widely applied in a plurality of fields.
The present proposal applies blockchain technology to the process of online shopping transaction payment in e-commerce. Firstly, a block chain network comprising a plurality of nodes is constructed, and the block chain network at least comprises a payment node, a collection node and a management node.
A payment node is a party that provides electronic money during a network transaction, commonly referred to as a buyer; the money receiving node is a party that receives electronic money and provides goods during a network transaction, and is generally referred to as a seller. The proposal does not limit the single function of the nodes added into the block chain network, namely, the nodes formed by the same computing equipment can be used as payment nodes and collection nodes. The system further comprises a management node, which is used for performing management actions such as authorization and supervision on transaction activities of a buyer and a seller, and is used as a centralized management mechanism for performing auxiliary management on a transaction process when a block chain network fails to operate normally. Specifically, the management node in the present proposal may be a banking system.
And S2, the target payment node issues order information to the management node, and the management node broadcasts authorization information to the blockchain network based on the order information and confirms the target collection node which is authorized to view the order information.
The step is used for limiting the viewing range of the order information, so that only authorized sellers and authorized nodes with order information viewing permission have the right to view the order information issued by the buyers, and other unrelated individuals or units have no right to view the order information.
After a target payment node in the proposal selects a commodity to be purchased and generates order information, the order information is encrypted through an asymmetric algorithm, the encrypted order information and a public key are issued to a management node, and the management node determines a node capable of checking the order information. The order information may specifically include contents such as an order number, a buyer ID, a product attribute, a seller ID, and a payment amount, where the product attribute field may further include a plurality of contents, such as a product name, a product category, and a product quantity. And after receiving the ciphertext of the order information, the management node decrypts the ciphertext through a preset public key corresponding to the target payment node to obtain the plaintext of the order information.
The management node confirms the target collection node with the authority of checking the order information according to the order information, generally, the target collection node is a node corresponding to the ID of the seller, and the order information can be checked only by an authorized node, so that the actions of carrying out malicious fraud and the like after the order information of the buyer is acquired by a lawbreaker can be effectively prevented. In specific implementation, the management node authorizes the target payment node by sending the public key of the target payment node. In addition, on the basis that the node corresponding to the seller ID is used as a target collection node capable of viewing order information, other nodes with authority of viewing order information, such as security nodes added into a white list and selling similar commodities, can be added, so that the other security nodes can recommend similar commodities to the buyer, a safe and healthy competition mechanism is introduced for market economy, and the shopping experience of the buyer is improved. Similarly, for the other nodes with the authority of viewing the order information, authorization is also carried out in a mode that the management node sends the public key of the target payment node.
This proposal is explained in further detail herein with respect to other nodes having the authority to view order information. First, the other nodes with the right to view order information are selected nodes from a white list by the target payment node. In the block chain network of the present disclosure, a white list node record representing a higher reputation is stored, where the white list node record is a trusted payment node or a trusted collection node determined by the management node according to a historical transaction record, and the conditions that the trusted payment node or the trusted collection node needs to satisfy at least include: (1) the order rate of the trusted payment node or the goodness of the trusted collection node is above a first threshold for a fixed period of time, which may be specified to be within approximately three months, approximately half a year, or approximately one year, for example, and which may be set to 98%; (2) the order distribution abnormal curvature of the trusted payment node or the trusted collection node in a fixed time period reaches below a second threshold value. The order distribution abnormal curvature refers to a curvature value corresponding to the highest point in an order quantity/time curve obtained by a statistical method. Generally speaking, the more evenly the order quantity is distributed in a fixed time period, the more gradually the order quantity/time curve is obtained, and therefore the curve value corresponding to the highest point is smaller. On the contrary, if there is a sudden surge in the order quantity in a fixed time period, the larger the surge quantity is relative to the order quantity at other time points, the larger the curvature value corresponding to the highest point is.
The proposal has important significance for the conditions which need to be met and are set by the trusted payment node or the trusted collection node. The condition (1) is used for screening nodes with good credibility, and the condition (2) is used for excluding nodes which may have a single-swiping behavior. Particularly for the condition (2), the condition that some illegal merchants falsely swipe the bills to make good comments can be effectively found, and for the payment nodes or the collection nodes with the number of orders being increased at a certain time, the payment nodes or the collection nodes are considered as dangerous nodes with the hidden danger of swiping the bills, and the dangerous nodes are automatically excluded from the white list nodes.
The trusted payment node or the trusted collection node that satisfies the two conditions is recorded in the white list. When the target payment node needs to add other nodes with the authority of viewing order information, a trusted payment node or a trusted collection node needs to be selected from the white list. The selected nodes can play a role in authentication in the transaction payment process and are used for confirming that the behaviors of the corresponding links are effective. For example, the order information submitted by the targeted payment node is validated.
And S3, the target collection node verifies the order information and broadcasts a verification result to an authorization node in the block chain network.
The step is used for the seller to verify the commodity information contained in the order, and the order verification result is broadcasted and issued to the node with the authority of checking the order information in the blockchain, so as to remind the buyer to prepare to enter the payment process. The proposal has been described in detail in step S2 as to how to select an authorized node having the right to view order information. That is, a trusted payment node or a trusted collection node is selected from the white list to confirm that the order verification result is valid. In order to guarantee the customer information, the order verification result in the present proposal only includes information such as an order number, a buyer ID, a seller ID, and a collection address link, and therefore, other nodes in the block chain cannot know the specific commodity content in the order information through the order verification result. Other nodes in the block chain participate in recording order verification results, so that smooth trading of orders is facilitated, and specific order information is guaranteed not to be revealed.
The target payment node broadcasts an issued payment information to authorized nodes in the blockchain network based on the verification result S4.
And when the order verification result is true, the target payment node is linked to pay equivalent commodity money according to the collection address in the order verification result, and the payment information is issued to the block chain network. Specifically, the payment information includes a buyer ID, a seller ID, and a payment amount.
And S5, the authorization node in the block chain network verifies the payment information and broadcasts and issues a payment verification result to all nodes in the block chain network.
When all other nodes in the blockchain network receive the payment information issued by the target payment node, the payment information can be verified. Specifically, the method comprises the steps of entering a bank transfer system through a network interface to verify whether the buyer ID, the seller ID and the payment amount contained in the payment information are correct or not, and issuing a verification result related to the payment information to a blockchain network.
The payment information is verified through the authorization node on the block chain, so that the phenomenon that a merchant cheats evaluation scores by forging false order information and swiping false payment information can be effectively avoided. Any authorized node on the blockchain may enter the bank transfer system to verify that the sheet payment node has actually paid money, which typically includes two cases, e.g., verified or not verified. For the condition of failing to pass the verification, considering the reasons of misoperation and the like, the proposal provides the preset times which are not less than three times, and the condition of failing to pass the verification occurs within the preset times and is not processed; however, when the payment information does not pass the verification for the preset number of times, the authorized node in the block chain has the right to mark the target payment node, for example, suspicious node reminding information is added in the verification result to remind all nodes in the block chain network to pay attention to the target payment node, and there may be a case of forging false payment information.
The proposal allows the suspicious nodes to operate and wash suspicions through integrity and legality, and meanwhile, punishment measures are taken for the suspicious nodes which are frequently unrevealed. For example, when the marked target payment node does not pass the verification of the payment information within the preset transaction times, the mark of the target payment node is deleted. For another example, when the marked target payment node is verified again within the preset transaction times, the target payment node is removed from the blockchain network, and a specific removal measure may be to prohibit the target payment node from issuing payment information to the blockchain network.
And S6, when the payment verification result is true, the target collection node issues delivery information to the blockchain network.
When the verification result of the payment information is determined to be correct, the target collection node, namely the seller can send the commodity through the logistics system, and meanwhile, the delivery information is broadcast and issued to the blockchain network. The specific content of the shipping information may include: sender ID, receiver ID, order number, etc.
And S7, the authorization node in the block chain network verifies the delivery information and broadcasts and issues a delivery verification result to the block chain network.
When all other nodes in the blockchain network receive the delivery information issued by the target collection node, the delivery information can be verified. Specifically, the method comprises the steps of entering the logistics system through an interface to verify whether a sender ID, a receiver ID and an order number contained in the delivery information are correct or not, and issuing a verification result about the delivery information to a block chain network.
The delivery information is verified through the authorization node on the block chain, so that the phenomenon that a merchant cheats evaluation scores by forging false order information and swiping false delivery information can be effectively avoided. Any authorized node on the blockchain can enter the logistics system to verify whether the target receiving node has actually delivered the goods, and the verification result generally comprises two cases, such as passing verification or failing verification. For the condition of failing to pass the verification, considering the reasons of misoperation and the like, the proposal provides the preset times which are not less than three times, and the condition of failing to pass the verification occurs within the preset times and is not processed; but when the delivery information is not verified for a preset number of times or exceeds, any node in the block chain has the right to mark the target collection node, for example, suspicious node reminding information is contained in the verification result, all nodes in the block chain network are reminded to pay attention to the target collection node, and there may be a case that the false delivery information is forged.
The proposal allows the suspicious nodes to operate and wash suspicions through integrity and legality, and meanwhile, punishment measures are taken for the suspicious nodes which are frequently unrevealed. For example, when the marked target collection node does not pass the verification of the delivery information within the preset transaction times, the mark of the target collection node is deleted. For another example, when the marked target receiving node fails to verify the shipping information again within the preset number of transactions, the target receiving node is removed from the blockchain network, and a specific removal measure may be to prohibit the target receiving node from issuing the shipping information to the blockchain network.
