[0030] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0031] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise," "include," etc. used herein indicate the presence of the features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0032] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0033] When expressions such as “at least one of A, B, and C, etc.” are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art (e.g., “a system having at least one of A, B, and C” should include but is not limited to systems having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, and C, etc.). When expressions such as “at least one of A, B, or C, etc.” are used, they should generally be interpreted in accordance with the meaning commonly understood by those skilled in the art (e.g., “a system having at least one of A, B, or C” should include but is not limited to systems having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, and C, etc.).

[0034] In online shopping scenarios, group buying often offers lower unit prices, making it increasingly popular among consumers. However, group buying typically requires that the total purchase quantity of multiple consumers within a group order exceed the minimum group size. Therefore, in this scenario, servers need to store a large amount of order information and update it in real time, increasing server pressure.

[0035] On the other hand, when e-commerce platforms launch group buying events, they typically set a maximum number of units per item for profit. Consequently, peak server pressure in the first half of the event is typically concentrated, while the latter half experiences less pressure. Therefore, adopting the related art solution of adding servers would result in significant waste of server resources in the latter half of the event, and adding servers would also increase costs, including server purchase, maintenance, and server space.

[0036] In view of this, an embodiment of the present disclosure provides an order processing method based on a blockchain network to reduce server performance pressure in group buying scenarios.

[0037] Specifically, embodiments of the present disclosure provide a blockchain-based order processing method, apparatus, electronic device, readable storage medium, and computer program product. The method includes: receiving a group purchase request message from a first client device, wherein the group purchase request message carries an item identifier and a purchase quantity; if the purchase quantity is less than a preset group purchase quantity, associating a first service node among multiple service nodes of the blockchain network with the first client device; generating a group purchase order based on the item identifier, wherein the group purchase order has an order identifier; and adding a block generated based on the order identifier and the group purchase request message to an order information ledger of the blockchain network.

[0041] Figure 1 The following schematically illustrates an exemplary system architecture to which a blockchain network-based order processing method according to an embodiment of the present disclosure can be applied. Figure 1 The examples shown are merely examples of system architectures to which the embodiments of the present disclosure may be applied, to help those skilled in the art understand the technical content of the present disclosure, but do not mean that the embodiments of the present disclosure may not be used in other devices, systems, environments or scenarios.

[0042] like Figure 1 As shown, the system architecture 100 according to this embodiment may include service nodes 101 , 102 , 103 , 104 , 105 , and 106 .

[0043] Business nodes 101, 102, 103, 104, 105, and 106 can be any node in the blockchain network.

[0044] The service nodes 101 , 102 , 103 , 104 , 105 , and 106 may have corresponding electronic devices, which may be client devices or server devices, including but not limited to mobile phones, computers, servers, and the like.

[0045] The service nodes 101 , 102 , 103 , 104 , 105 , and 106 may be connected via a network, which may include various connection types, such as wired and / or wireless communication links.

[0046] Business nodes 101, 102, 103, 104, 105, and 106 may be configured with a blockchain ledger, the contents of which may be synchronized in real time over the network.

[0047] It should be noted that the order processing method based on the blockchain network provided in the embodiment of the present disclosure can generally be executed by an electronic device corresponding to any one of the business nodes 101, 102, 103, 104, 105, and 106; accordingly, the order processing device based on the blockchain network provided in the embodiment of the present disclosure can generally be set in an electronic device corresponding to any one of the business nodes 101, 102, 103, 104, 105, and 106.

[0048] It should be understood that Figure 1 The number of service nodes in FIG is only for illustration. Any number of service nodes may be provided according to implementation requirements.

[0049] Figure 2 The flowchart of the method for processing group orders based on a blockchain network according to an embodiment of the present disclosure is schematically shown.

[0050] like Figure 2 As shown, the method includes operations S201 to S204.

[0051] In operation S201, a group creation request message is received from a first client device, wherein the group creation request message carries an item identifier and a purchase quantity.

[0052] In operation S202 , when the purchase quantity is less than a preset group purchase quantity, a first business node among multiple business nodes of the blockchain network is associated with the first client device.

[0053] In operation S203 , a group purchase order is generated based on the item identifier, wherein the group purchase order has an order identifier.

[0054] In operation S204, the block generated based on the order identifier and the group creation request message is added to the order information ledger of the blockchain network.

[0055] According to an embodiment of the present disclosure, there may be multiple business nodes in a blockchain network, and one of the multiple business nodes establishes an association relationship with a server device.

[0056] According to an embodiment of the present disclosure, the first client device may be any electronic device that supports a specific client application, such as a mobile phone or a computer. The specific client application may be a shopping application. A user may perform a click operation within the shopping application. Upon receiving the click operation, the first client device may generate a group creation request message based on the clicked target item.

[0057] According to an embodiment of the present disclosure, the first client device may send a group creation request message to the server device based on the network address of the server device.

[0058] In some embodiments, in addition to the item identification and purchase quantity, the group creation request message may also include information such as the group creation user identification, the network address of the first client device, the payment bill identification, an encrypted verification field, etc. This information can be used to verify the user's identity, ship the items after the group is confirmed, and refund if the group fails to be formed.

[0059] According to an embodiment of the present disclosure, the preset group purchase quantity can be set according to a specific business scenario.

[0060] According to an embodiment of the present disclosure, when the purchase quantity in the group purchase request message is greater than or equal to the preset group purchase quantity, it can be considered that the order corresponding to the group purchase request message can be formed into a separate group, and the server device can return a message requesting the provision of shipping information to the first client device so as to directly enter the shipping process, or enter the shipping process after the pressure on the server device drops.

[0061] According to an embodiment of the present disclosure, there may be multiple group purchase orders for one item at the same time, and each group purchase order uniquely corresponds to an item identifier and an order identifier of the group purchase order.

[0062] According to an embodiment of the present disclosure, the order information ledger may be a blockchain ledger in a blockchain network, and the order information ledger may be synchronized to each business node of the blockchain network in real time.

[0063] According to an embodiment of the present disclosure, when a request to start a group purchase is received from a first client device, it is determined whether a separate group purchase can be formed based on the purchase quantity submitted by the first client device. If a separate group purchase cannot be formed, the first client device is associated with a business node in the blockchain, and the relevant information for starting the group purchase is stored in the order information ledger. Blockchain technology can utilize the storage resources of the client device, and the order information when the group purchase is made can be stored on the client device, reducing the consumption of server resources. Therefore, it at least partially overcomes the technical problem in the related art that adding servers will cause waste of resources, thereby effectively reducing the operation and maintenance costs of the e-commerce platform, and realizing the transfer of server pressure without adding servers, thereby improving the processing efficiency of group purchase orders.

[0064] Reference below Figures 3 to 6 , combined with specific embodiments Figure 2 The method shown is further explained.

[0065] Figure 3 The flowchart of the group order processing method based on the blockchain network according to an embodiment of the present disclosure is schematically shown.

[0066] like Figure 3 As shown, the method includes operations S301 to S310.

[0067] It should be noted that, unless it is explicitly stated that there is a sequence of execution between different operations shown in the flowchart in the embodiments of the present disclosure, or there is a sequence of execution between different operations in technical implementation, otherwise, the execution order between multiple operations may not be prioritized, and multiple operations may also be executed simultaneously.

[0068] In operation S301, a group joining request message is received from a second client device.

[0069] In operation S302, a first target group purchase order is determined based on the group joining request message.

[0070] In operation S303, N first target business nodes associated with the first target group purchase order in the blockchain network are determined.

[0071] In operation S304 , a network address list is generated based on the network addresses of the first target client devices associated with the N first target service nodes.

[0072] In operation S305 , the network address list is returned to the second client device.

[0073] In operation S306 , a feedback message is received from the first target client device.

[0074] In operation S307 , it is determined whether the first target service nodes have reached a consensus. If it is determined that the first target service nodes have reached a consensus, operation S308 is performed. If it is determined that the first target service nodes have not reached a consensus, operation S310 is performed.

[0075] In operation S308, a second business node among the plurality of business nodes of the blockchain network is associated with the second client device.

[0076] In operation S309, the block generated based on the group joining request message is added to the order information ledger.

[0077] In operation S310 , feedback information indicating refusal to join the group is sent to the second client device.

[0078] According to an embodiment of the present disclosure, the group joining request message may carry the network address of the second client device, the first target item identifier, the first target order identifier and the target purchase quantity; accordingly, the group creation request message may also carry the network address of the first client device.

[0079] According to an embodiment of the present disclosure, the second client device can be any electronic device that supports a specific client application, such as a mobile phone or a computer. The specific client application can be a shopping application. A user can perform a click operation within the shopping application. Upon receiving the click operation, the second client device assembles a group joining request message based on the target item and target group corresponding to the clicked group group option.

[0080] In some embodiments, corresponding to the group creation request message, the group joining request message may also carry information such as the group joining user identifier, payment bill representation, and encryption verification field.

[0081] According to an embodiment of the present disclosure, the first target group purchase order may be determined based on the first target item identifier and the first target order identifier.

[0082] According to an embodiment of the present disclosure, N may be a positive integer greater than or equal to 1.

[0083] According to an embodiment of the present disclosure, based on the contents of multiple blocks in the order information ledger, one or more group purchase orders associated with each business node can be determined, and then based on the order identifier of the first target group purchase order, N first target business nodes associated with the first target group purchase order can be determined.

[0084] According to an embodiment of the present disclosure, based on the contents of multiple blocks in the order information ledger, the network address of the client device associated with each business node can be determined; the network address list may include the network addresses of N first target client devices.

[0085] According to an embodiment of the present disclosure, after returning the network address list to the second client device, the second client device may send group joining request messages to each of the N first target client devices based on the network address list.

[0086] According to an embodiment of the present disclosure, after receiving a group-joining request message, the first target client device can determine whether the total purchase quantity meets the group-joining criteria based on the target purchase quantity carried in the group-joining request message and the current purchase quantity determined based on the order information ledger, and send a feedback message to the server device based on the judgment result. Specifically, the first target client device determines the current purchase quantity of the first target group purchase order based on the order information ledger of the first target business node; if the current purchase quantity is less than the preset group purchase quantity, the first target client device generates a feedback message indicating that it agrees to join the group; and if the current purchase quantity is greater than or equal to the preset group purchase quantity, the first target client device generates a feedback message indicating that it refuses to join the group.

[0087] According to an embodiment of the present disclosure, the current purchase quantity may be the sum of the purchase quantities of the target item by users corresponding to the N first target service nodes.

[0088] According to an embodiment of the present disclosure, a first consensus result of N first target client devices can be determined based on all received feedback messages. For example, when the number of feedback messages indicating agreement to join the group in the received feedback messages is greater than or equal to M, a first consensus result indicating agreement to join the group can be obtained, wherein M is the product of N and a preset consensus ratio; when the number of feedback messages indicating agreement to join the group in the received feedback messages is less than M, a first consensus result indicating refusal to join the group can be obtained; wherein the preset consensus ratio can be set according to the specific application scenario, for example, it can be set to 3 / 5, 5 / 6, 1, etc. For another example, when the number of received feedback messages is greater than or equal to N / 2, and the received feedback messages do not indicate agreement to join the group, a first consensus result indicating agreement to join the group can be obtained; otherwise, a first consensus result indicating refusal to join the group can be obtained.

[0089] According to an embodiment of the present disclosure, after receiving the feedback information of rejection of group participation, the second client device can display the information to the user through the display device of the second client device, so that the user can perform subsequent refund operations and group opening and group participation operations.

[0090] According to the embodiments of the present disclosure, through the above-mentioned technical means, in the group joining process, the server-side device only needs to perform data communication and statistical operations, while the specific logical operations such as judging whether it is possible to join the group are performed by the client device, thereby effectively reducing the operating pressure of the server-side device and improving the processing efficiency of puzzle orders.

[0091] Figure 4 The present invention schematically illustrates a flowchart of a method for interaction between business nodes in a blockchain network according to an embodiment of the present disclosure.

[0092] like Figure 4 As shown, the method includes operations S401 to S403.

[0093] In operation S401, it is determined whether a scheduled task is triggered; if it is determined that the scheduled task is triggered, operation S402 is executed; if it is determined that the scheduled task is not triggered, the process returns to operation S401.

[0094] In operation S402, a service node in the blockchain network sends a heartbeat message to other nodes in the blockchain network.

[0095] In operation S403, other nodes reach a consensus on the contents of the order information ledger.

[0096] According to an embodiment of the present disclosure, a scheduled task may be pre-set in each business node. The scheduled task may be to send a heartbeat message to other business nodes in the blockchain network at regular intervals to verify the order information ledger stored in each business node.

[0097] According to an embodiment of the present disclosure, the heartbeat message may carry summary information of the order information ledger. For example, the summary information may be the MD5 code of the order information ledger in the service node.

[0098] According to an embodiment of the present disclosure, other nodes may reach a consensus on the contents of the order information ledger by synchronizing the contents of the order information ledger based on the contents of more than half of the nodes, and completing or correcting the contents of the order information ledger in the inconsistent business nodes.

[0099] In some embodiments, the other nodes may include a server node associated with the server device. In this case, the service node may also add the network address of the current client device to the heartbeat message so that the server node uses the current network address to update the originally recorded network address to update the network address list.

[0100] In some embodiments, after receiving the heartbeat message from the business node, the server node may also return a response message to the business node, which may carry a list of items for which the puzzle has been completed. After receiving the list of items, the client device corresponding to the business node may determine whether the target item of the group purchase order corresponding to the client device is on the list; if the target item of the group purchase order corresponding to the client device is on the list, a feedback message "The rush for xx item has ended, failed to grab xx item, automatic refund in progress" may be displayed to the user on the display device; thereafter, the client device may send the locally recorded data to the server device, so that after the operating pressure of the server device decreases, the server device can verify and reconcile the data with the data of other nodes participating in the same group and then perform the refund operation.

[0101] Figure 5 The flowchart of the method for processing orders after group formation based on the blockchain network according to an embodiment of the present disclosure is schematically shown.

[0102] like Figure 5 As shown, the method includes operations S501 to S506.

[0103] In operation S501 , a clumping feedback message is received from a second target client device.

[0104] In operation S502, determine whether the number of received clustering feedback messages is less than a preset threshold; if it is determined that the number of received clustering feedback messages is greater than or equal to the preset threshold, perform operation S503; if it is determined that the number of received clustering feedback messages is less than the preset threshold, return to perform operation S501 to continue receiving clustering feedback messages from other second target client devices.

[0105] In operation S503, it is determined whether the second target service nodes have reached a consensus; if it is determined that the second target service nodes have reached a consensus, operation S504 is performed; if it is determined that the second target service nodes have not reached a consensus, operation S506 is performed.

[0106] In operation S504 , a business order is generated based on the second consensus result and the second target group purchase order.

[0107] In operation S505, the business order is stored in a local storage device.

[0131] According to an embodiment of the present disclosure, whether the third target client device reaches a consensus can be determined based on whether the content of the received response message is consistent. Its consensus process can adopt the same or similar judgment scheme as other consensus processes of the embodiment of the present disclosure, which will not be repeated here.

[0132] According to an embodiment of the present disclosure, the local storage device may be a storage device of a server device.

[0133] According to the embodiments of the present disclosure, in the server-centric working mode, requests for starting or joining a group initiated by a client device are all processed by the server device, and the computing resources of the client device are no longer consumed for information storage and processing operations.
