Detailed Description

Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. It should be understood that the description is illustrative only and is not intended to limit the scope of the present disclosure. In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present disclosure.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. The terms "comprises," "comprising," and the like, as used herein, specify the presence of stated features, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, steps, operations, or components.

All terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art unless otherwise defined. It is noted that the terms used herein should be interpreted as having a meaning that is consistent with the context of this specification and should not be interpreted in an idealized or overly formal sense.

Where a convention analogous to "at least one of A, B and C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B and C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.). Where a convention analogous to "A, B or at least one of C, etc." is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., "a system having at least one of A, B or C" would include but not be limited to systems that have a alone, B alone, C alone, a and B together, a and C together, B and C together, and/or A, B, C together, etc.).

In an online shopping scenario, group-together shopping generally means a lower unit price, and thus is increasingly favored by consumers. However, when group-combining is performed for first-aid purchase, the total purchase quantity of a plurality of consumers in one group order is generally required to be greater than the lowest group quantity, and therefore, in this scenario, the server needs to store a large amount of order information and update the order information in real time, thereby increasing the pressure of the server.

On the other hand, when the group-piecing shopping campaign is started, the e-commerce platform generally sets the total number of sold items per item in consideration of profit, so that in the group-piecing shopping campaign scene, the pressure peak borne by the server is generally concentrated in the first half of the campaign, and the server has less pressure in the second half. Therefore, if the solution of adding servers in the related art is adopted, the resources of the servers are greatly wasted in the latter half of the activity, and the addition of the servers themselves causes the cost rise, including the purchase cost, the maintenance cost, the occupation cost of the servers themselves, and the like.

In view of this, an embodiment of the present disclosure provides an order processing method based on a block chain network, so as to reduce the performance pressure of a server in a group-piecing and group-robbing scenario.

Specifically, the first target client device determines the current purchase quantity of the first target group purchase order based on the order information book of the first target service node; under the condition that the current purchase quantity is smaller than the preset group purchase quantity, the first target client device generates a feedback message which indicates that the participation group is agreed; and under the condition that the current purchase quantity is larger than or equal to the preset group purchase quantity, the first target client equipment generates a feedback message which indicates that the participation group is rejected.

According to an embodiment of the present disclosure, the current purchase quantity may be a sum of purchase quantities of the target items by the users corresponding to the N first target business nodes.

According to an embodiment of the present disclosure, the first common identification result of the N first target client devices may be determined based on all the received feedback packets. For example, a first consensus result expressed as an agreement group may be obtained when the number of feedback messages expressed as the agreement group in the received feedback messages is greater than or equal to M, where M is a product of N and a preset consensus ratio; under the condition that the number of feedback messages which are indicated as the participation groups are agreed in the received feedback messages is less than M, obtaining a first consensus result which is indicated as the participation groups refused; the preset consensus ratio may be set according to a specific application scenario, and for example, may be set to 3/5, 5/6, 1, or the like. For another example, the first consensus result expressed as the agreement group may be obtained when the number of the received feedback messages is greater than or equal to N/2 and the received feedback messages are expressed as the agreement group; otherwise, a first consensus result is obtained, which is denoted as a rejection of the group.

According to the embodiment of the disclosure, after receiving the feedback information of rejecting participating in the group, the second client device may display the information to the user through a display device of the second client device, so that the user can perform subsequent refund operation and group opening and participating operation.
