This application also provides an order status update method based on blockchain.

Referring to FIG. 2, FIG. 2 is a schematic flowchart of a first embodiment of a method for updating an order status based on a blockchain in this application.

The embodiment of the application provides an embodiment of the method for updating the order status based on the blockchain. It should be noted that although the logical sequence is shown in the flowchart, in some cases, the sequence may be different from here. Perform the steps shown or described.

The order status update method based on the blockchain is applied to the blockchain. A blockchain is a chain composed of a series of blocks. In addition to recording the data of this block, each block also records the Hash (hash) value of the previous block. In this way, a chain is formed. There are two core concepts of the blockchain, one is cryptography and the other is decentralization. Based on these two concepts, the historical information on the blockchain cannot be tampered with. A block consists of a block header and a block body. The block header definition includes important fields such as the height of the block and the hash value of the previous block. The block body mainly stores transaction data. Nodes specifically refer to network nodes that participate in the blockchain network for transactions and data exchange. Each independent institution member can have one or more transaction nodes. Each transaction node is a set of physical networks, computers, and blockchain applications. The combination of software and database. The nodes are connected to each other through TCP/IP (Transmission Control Protocol/Internet Protocol, Transmission Control Protocol/Internet Protocol) protocol. In the various embodiments of the method for updating the order status based on the blockchain, for ease of description, the execution subject is omitted to describe the various embodiments. Blockchain-based order status update methods include:

Step S10: After detecting that the supply node uploads the commodity information of the commodity for sale to the blockchain, it is detected whether a purchase instruction triggered by the purchasing node to purchase the commodity for sale is received.

In the embodiment of the present application, the supply node corresponding to the supplier system and the purchasing node corresponding to the buyer system are both connected to the blockchain and become a node in the blockchain. The PBFT (Practical Byzantine Fault Tolerance, Practical Byzantine Fault Tolerance) consensus algorithm is adopted between each node of the blockchain, and each node of the blockchain jointly confirms the transactions in the blockchain. Purchasing nodes and supply nodes use the same API (Application Programming Interface) to connect to the blockchain, avoiding the existence of different API interfaces between different merchants (purchasers and suppliers) in the prior art. In the process of data interaction between different merchants, different interface standards need to be compatible, and the cost of data interaction between different merchants is high. This improves the access efficiency of the procurement node and the supply node in the blockchain, and reduces the procurement node and supply. The cost of node access to the blockchain. In the process of connecting to the blockchain, the open platform of the blockchain can provide an open platform interface, and the buyer system and supplier system can be connected to the blockchain through the open platform interface and become a node in the blockchain ; Or connect the platform that connects with the buyer system and supplier system to the development platform of the blockchain; or connect the buyer system and supplier system as a node of the blockchain to the card coupons of the blockchain Procurement platform.

When the supply node wants to sell goods, such as selling various types of coupons or other goods, the supply node can upload the product information of the goods for sale to the blockchain to store the product information of the goods for sale in the zone Block chain. Among them, the product information includes but is not limited to product type, product unit price and product usage. For example, when the commodity for sale is a coupon, the product information includes but is not limited to the type of the coupon, the unit price of the coupon, the time of use of the coupon, and the location of the coupon. After the product information of the product for sale is successfully stored in the blockchain, it is detected whether a purchase instruction triggered by the purchasing node to purchase the product for sale is received. It should be noted that if the supply node has authorized the purchasing node to obtain its product information, after successfully storing the product information of the product for sale in the blockchain, the purchasing node can obtain the product information of the product for sale from the blockchain. At the time, the purchasing user corresponding to the purchasing node can trigger the purchasing instruction according to specific needs.

Among them, purchasing users can trigger different types of purchasing instructions in the purchasing node at different stages. In this embodiment of the application, the purchase instruction includes an upload instruction for uploading the order information corresponding to the purchase order for the purchased product, a download instruction for downloading the attribute information of the product for sale, and a payment instruction for paying the amount corresponding to the purchase order.

Step S20, if the purchase instruction is received, update the order status of the purchase order corresponding to the purchase of the goods for sale by the purchasing node in the blockchain according to the purchase instruction to obtain the updated order status .

When the purchase instruction triggered by the purchase node is received, the order status of the purchase order corresponding to the purchase of goods for sale by the purchase node is updated in the blockchain according to the purchase execution, and the updated order status is obtained. It is understandable that through the order information in the purchase order, the type and quantity of the goods purchased by the purchasing node can be known. In the embodiment of this application, the order status includes but is not limited to the generated status, the paid status and the completed status. Further, if the purchase instruction is not received, continue to detect whether the purchase instruction triggered by the purchase node to purchase the commodity for sale is received.

Further, if the purchase instruction is an upload instruction for uploading order information of the purchase node to purchase the commodity for sale, step S20 includes:

Step a: If the upload instruction is received, a purchase order for the purchasing node to purchase the commodity for sale is generated in the blockchain according to the upload instruction, and the state of the purchase order is initialized to Generate status and get the updated order status.

If an upload instruction of the purchase order information of the item for sale uploaded by the purchase node is received, a purchase order for the purchase node to purchase the item for sale is generated in the blockchain according to the upload instruction, and the state of the purchase order is initialized to the generated state, Get the updated order status. It should be noted that after receiving the upload instruction, a purchase order is generated according to the order information, and the purchase order is updated from the stateless to the generated state.

Further, the step of generating a purchase order for the purchase node to purchase the commodity for sale in the blockchain according to the upload instruction includes:

Step b: Obtain order information corresponding to the upload instruction in the blockchain, and obtain order parameters for creating an order from the order information.

Step c: Generate a purchase order for the purchase node to purchase the commodity for sale based on the order parameters and preset order generation rules.

Specifically, the order information is obtained from the upload instruction, and the order parameters required to create the order are obtained from the order information, and then based on the obtained order parameters and preset order generation rules, a purchase order for the purchase node to purchase goods for sale is generated . Order parameters include, but are not limited to, the order number, the quantity and time of purchase of goods for sale. The preset order generation rules include but are not limited to: a. The preset order generation rules include: adding order parameters to the order template in advance In the set position, to generate a purchase order; b. Use the preset connector to connect the order parameters to obtain the purchase order. Specifically: a. Extract the order number, quantity and time in the order information of the goods for sale, and add the order number, quantity and time to the position set in the order template in advance to generate a purchase order; b. Extract the order for the goods for sale The order number and quantity in the information are connected with the order number and quantity using the preset connector to obtain the purchase order. It should be noted that the purchase orders are generated through the above-mentioned methods to unify the orders of different purchasers and suppliers, and there is no need to generate different forms of orders in a personalized manner. Compared with the traditional way of generating orders, which is customized by suppliers, this Application makes the generation of orders more convenient, and the efficiency of unified generation is higher.

Further, if the purchase instruction is a download instruction for the purchase node to download the attribute information of the commodity for sale, step S20 includes:

Step d, if the download instruction is received, the order status of the purchase order corresponding to the purchase of the commodity for sale by the purchasing node is updated to the completed state in the blockchain according to the download instruction, and after the update is obtained The status of the order.

If the download instruction to download the attribute information of the item for sale uploaded by the purchasing node is received, the order status of the purchase order corresponding to the item purchased by the purchasing node for sale is updated to the completed state according to the download instruction in the blockchain, and the updated state is obtained. Order Status. Specifically, the order status is updated from the paid status to the completed status. Attribute information is information that can uniquely identify a certain product. A certain product can be used or obtained through the attribute information. For example, the attribute information corresponding to a coupon is a code, and the coupon can be used through the coupon code.

In step S30, the updated order status is synchronized to the purchasing node and the supply node, so that the purchasing node and the supply node can perform corresponding operations according to the updated order status.

When the updated order status is obtained, the updated order status is synchronized to the purchasing node and the supply node, so that the purchasing node and the supply node can perform corresponding operations according to the updated order status. It is understandable that in the process of acquiring the order status of the purchase order by the purchasing node and the supply node, the purchasing node and the supply node do not need to be connected to each other, and the order status can be directly obtained from the blockchain. Specifically, when the generated state of the purchase order is synchronized to the purchase node and the supply node, the supply node obtains the order information in the blockchain, and freezes the goods that the purchase node needs to purchase according to the order information, so as to avoid the purchase node need to purchase The situation that the product of the product is purchased by other procurement nodes, that is, to avoid the situation of one thing two selling. Specifically, the supply node can add a freeze identifier to the attribute information of the product corresponding to the order information to freeze the product that the purchase node needs to purchase. In this embodiment of the application, the expression form of the freeze identifier is not limited, and the freeze identifier can be numbers and letters. Or sign etc. The purchasing node triggers a payment instruction according to the operation of the purchasing user to pay the corresponding amount of the purchase order.

Further, in order to ensure the success rate of the transaction between the procurement node and the supply node, when the supply node freezes the goods that the procurement node needs to purchase, the supply node uploads the successful freeze message to the blockchain for the procurement node to get from the zone. The success message is obtained in the block chain, and the purchasing user is prompted to trigger the payment instruction according to the success message.

When the completed status of the purchase order is synchronized to the purchase node and the supply node, the purchase node can output the purchase prompt information to remind the purchasing user according to the purchase prompt information that the goods have been successfully purchased from the supply node; the supply node can output the supply The prompt information is used to prompt the supplying user according to the supply prompting information that the goods for sale have been successfully supplied to the purchasing user.

In this embodiment, after detecting that the supply node uploads the product information of the product for sale to the blockchain, and receives the purchase instruction for purchasing the product for sale triggered by the purchase node, the purchase node is updated in the blockchain according to the purchase instruction Purchasing goods for sale corresponds to the order status of the purchase order, obtains the updated order status, and synchronizes the updated order status to the purchasing node and the supply node, so that the purchasing node and the supply node can execute the corresponding according to the updated order status Operation, realize the synchronization of the order status of the purchase order in the buyer system and the supplier system through the blockchain. The order status is subject to the status in the blockchain, which improves the consistency of the order status in the supplier system and the buyer system Sex.

Further, the order status of the purchase order is synchronized to the purchase node and the supply node through the blockchain, which realizes that the supplier system and the purchaser system no longer need to record the order status of the purchase order, and the purchaser system and the supplier system can be simultaneously Obtain the order status of the purchase order from the blockchain; it avoids that the order status in the prior art is based on the supplier system. The buyer system needs to intelligently and actively inquire or wait for the order status notification from the supplier system, and avoids When a large number of commodities are traded, a large number of order status query requests or order status notification messages are generated, which reduces the system pressure of the buyer system and the supplier system, and improves the timeliness of the buyer system to obtain the status of the purchase order.

Furthermore, since the order status in the prior art is based on the supplier system, the buyer system can only passively synchronize the order status, so there is a risk that the supplier system will tamper with the order status. Since the order status is closely related to funds, if The order status is tampered with, which will reduce the security of commodity transactions. The embodiment of the application uses the blockchain to synchronize the order status, thereby ensuring that the order status of the purchase order is not tampered with through the immutable modification of the data in the blockchain, ensuring the accuracy of the order status, and improving online commodity transactions The security, and the on-chain audit of orders and the traceability of data are realized through the blockchain.

Further, a second embodiment of the method for updating the order status based on the blockchain of this application is proposed.

The difference between the second embodiment of the blockchain-based order status update method and the first embodiment of the blockchain-based order status update method is that, referring to FIG. 3, if the purchase instruction is for the purchase node to pay For the payment instruction of the corresponding amount of the purchase order, step S20 includes:

Step S21, if the payment instruction is received, the order status of the purchase order corresponding to the purchase of the commodity for sale by the purchasing node is updated to the paid status in the blockchain according to the payment instruction, and the updated status is obtained The status of the order.

It should be noted that the payment instruction can optionally prompt the purchasing user to trigger based on the interface periodically within a preset time after the purchase order is generated. In addition, it can also optionally be uploaded by the supply node after the supply node freezes the goods that the purchase node needs to purchase The successful success message is frozen in the blockchain so that the purchasing node can obtain the success message from the blockchain, and prompt the purchasing user to trigger the payment instruction based on the interface according to the success message.

After receiving the payment instruction sent by the purchasing node to pay the corresponding amount of the purchase order, the order status of the purchase order corresponding to the purchase of goods for sale by the purchasing node is updated to the paid state according to the payment instruction in the blockchain. Specifically, the purchase The status of the order is updated from the generated status to the paid status, and the updated order status is obtained.

Specifically, when the paid status of the purchase order is synchronized to the purchase node and the supply node, the supply node stores the attribute information of the corresponding commodity for sale in the blockchain according to the purchase order in the paid state. At this time, the purchase node The attribute information of the commodity for sale can be downloaded in the blockchain, that is, a download instruction to download the attribute information of the commodity for sale is triggered.

Further, in order to ensure the timeliness of the purchase order, after the purchase order is in the effective state, it is determined whether a payment instruction is received within a preset time period. If the payment instruction is received within the preset time period, the order status of the purchase order will be changed from the generated state to the updated state according to the payment instruction in the blockchain, and the updated order status will be obtained; if not within the preset time period After receiving the payment instruction, the purchase order stored in the blockchain is closed, and the order status is changed from the generated state to the closed state. Among them, the preset time length can be set according to specific needs, such as 3 minutes, 10 minutes, or 30 minutes, etc. By setting the preset time length, the order can be prevented from being unpaid for a long time.

In this embodiment, after receiving a payment instruction for the purchase node to pay the corresponding amount of the purchase order, the order status of the purchase order corresponding to the purchase of goods for sale by the purchase node is updated to the paid state in the blockchain according to the payment instruction to obtain the updated state The order status of the purchase order is synchronized to the purchase node and the supply node through the blockchain, which improves the consistency of the order status in the supplier system and the buyer system.

Further, a third embodiment of the method for updating the order status based on the blockchain of the present application is proposed.

Real-time or timing detection whether a clearing order is detected. If a clearing instruction is detected, the blockchain shared ledger is obtained. Wherein, the clearing instruction may be sent by the purchasing node or the supply node. In the blockchain shared ledger, the transaction information of each commodity transaction is stored. The transaction information includes but is not limited to the name of the buyer, the name of the supplier, the transaction time, the name of the purchased commodity, the quantity and the amount. When the blockchain shared ledger is obtained, the purchase order in the paid state is cleared according to the blockchain shared ledger, and the clearing result is obtained, and the clearing result is correspondingly sent to the supply node and the purchase node. In the clearing result, the quantity and name of the goods supplied by the supply node and the amount of the goods supplied, etc., and the quantity and name of the goods purchased by the procurement node, and the amount paid for the purchased goods are included. Further, if the clearing instruction is not detected, continue to detect whether the clearing instruction is detected.

Further, the method for updating the order status based on the blockchain further includes:

Step g: Obtain the current time, and determine whether the current time is within a preset liquidation time period.

Step h, if the current time is within the preset clearing time period, trigger the clearing instruction.

Further, the current time is obtained, and it is determined whether the current time is within the preset liquidation time period. If it is determined that the current time is within the preset clearing time period, the clearing instruction is automatically triggered; if it is determined that the current time is not within the preset clearing time period, continue to determine whether the current time is within the preset clearing time period. Among them, the preset clearing time period can be set according to specific needs. For example, the preset clearing time period can be set between 4:00 and 4:30 pm every day, or between 5:00 and 5:45.

Step i: Send the clearing result to the transfer agency, so that the transfer agency transfers the corresponding amount from the purchase node account to the supply node account according to the clearing result.

Further, when the clearing result is obtained, the clearing result is sent to the transfer agency. After the transfer agency receives the clearing result, the transfer agency transfers the corresponding amount from the purchase node account to the supply node account according to the clearing result, specifically, transfers the amount corresponding to the purchase order to the supply node account. It should be noted that the clearing result sent to the purchasing node only includes information related to the purchasing node, such as the quantity and name of the goods purchased by the purchasing node, and the amount paid for the purchased goods; the clearing result sent to the supply node Only the information related to the supply node is included, such as the quantity, name, and amount of goods supplied by the supply node; and the clearing result sent to the transfer agency includes the information related to the purchase node and the related information of the supply node.
