For example, the operator in the embodiment of the present invention may be, but is not limited to, a floating merchant, and the like. It should be noted that the specific nature of the operator can be determined by those skilled in the art according to the actual situation, and the above description is only an example and is not intended to limit the scope of the invention.

For example, the deduction of the deposit made for the user based on the deposit amount may be, but is not limited to, deducting the corresponding deposit amount from funds in a payment account corresponding to the user under the condition of authorization of the user. It should be noted that, the specific implementation manner of making a payment deduction for the subscription based on the subscription amount may be determined by those skilled in the art according to actual situations, and the above description is only an example, and is not limited thereto.

For example, the operator performs the target transaction with the user according to the transaction item information and the transaction time information, and may prepare, but not limited to, transaction items of corresponding types and quantities according to the transaction item information for the operator, and carry the transaction items to participate in the target transaction at the time corresponding to the transaction time information and perform the target transaction with the user. It should be noted that, for the specific implementation manner of the operator performing the target transaction with the user according to the transaction article information and the transaction time information, the specific implementation manner may be determined by those skilled in the art according to actual situations, and the above description is only an example, and does not limit this.

It should be noted that the specific nature, source, content, etc. of the subscription record information can be determined by those skilled in the art according to the actual situation, and the above description is only an example, and is not limited thereto.

For example, the determining, based on the subscription record information sent by the operator node, one or more first target user nodes subscribing to the operator node in the block chain may be, but is not limited to, performing analysis based on the subscription record information to obtain node information of one or more user nodes subscribing to the operator node, which is included in the subscription record information, and then performing analysis or query based on the node information to obtain the corresponding first target user nodes. It should be noted that, for a specific implementation manner of determining, based on the subscription record information sent by the operator node, one or more first target user nodes subscribing to the operator node in the block chain, may be determined by those skilled in the art according to actual situations, and the foregoing description is only an example, and does not limit this.

It should be noted that, the content of the expected operation time can be determined by those skilled in the art according to the actual situation, and the above description is only an example, and is not limited thereto.

For example, the expected delivered item identifier corresponding to the expected operation time may be, but is not limited to, an item name, an item type or an item number of an item that the operator expects to sell, offer or deliver in the operation process corresponding to the expected operation time. It should be noted that the specific nature and content of the expected delivered item identifier corresponding to the expected operation time can be determined by those skilled in the art according to the actual situation, and the above description is only an example and is not limiting.

For example, an expected deliverable identification may correspond to an expected amount of deliverable and an expected unit price for the item.

Through the steps, before the operator starts to operate, the specific expected operation time and various related information of the articles expected to be provided can be pushed to the user node subscribing the operator node corresponding to the operator, so that the corresponding user can accurately know the expected operation time of the operator concerned by the corresponding user and various related information of the articles expected to be provided in advance for reference, the user subscribing the operator can more accurately and conveniently determine whether to perform offline transaction with the operator based on the actual situation, and the specific scheme (for example, the number of articles of a certain model which are preset in advance and the time when the online transaction is performed with the operator to start the transaction and the like) of the offline transaction with the operator is determined in advance based on the actual situation, thereby better meeting the transaction requirements and experiences of the users of the relevant subscriber operators, and facilitating the user to perform the offline transaction with the operator in mind more smoothly, and further improving the transaction efficiency.

For example, in step S401, the transaction item information may be, but is not limited to, analyzed to obtain a target item identifier corresponding to or included in the transaction item information, a target item quantity corresponding to the target item identifier, and a target item unit price. The target item identifier may be, but is not limited to, a type, a number, a name, or the like of the item, one transaction item information corresponds to one or more target item identifiers, and one target item identifier corresponds to one target item quantity and one target item unit price. It should be noted that, the specific implementation manner of step S401, the specific form of the target item identifier, and the corresponding relationship in the transaction item information may be determined by those skilled in the art according to actual situations, and the above description is only an example, and does not limit this.

For example, in the step S402, the target item quantity of each target item identifier and the target item unit price may be multiplied to obtain an item price corresponding to each target item identifier, and then the item prices corresponding to each target item identifier are superimposed to obtain the total price of the transaction item. It should be noted that, for the specific implementation manner of step S402, it can be determined by those skilled in the art according to practical situations, and the above description is only an example, and is not limited thereto.

For example, the step S403 may be, but not limited to, multiplying the subscription ratio by the total price of the transaction item to determine the subscription amount. Wherein, the ratio of the gold can be but not limited to 2%, 5% or 10%, etc., but is generally not more than or equal to 20%. The specific implementation manner of step S403, the specific value of the gold fixing ratio, and the like can be determined by those skilled in the art according to actual circumstances, and the above description is only an example, and is not limited thereto.

Through the steps, the information of the transaction articles can be fully analyzed, the total price of the transaction articles can be more accurately determined according to the specific article identification, the corresponding quantity and the unit price, so that the accuracy of determining the amount of the deposit according to the total price of the transaction articles and the credit weight is improved, the deposit and deduction can be more accurately performed on the user, the user can further provide sufficient and accurate guarantee for the offline transaction in advance, the user can be promoted to participate in the offline transaction in the order of the user, even if the user runs the order, the sufficient deposit provided in advance can further make up the cost and time consumed by the operator in the preparation process to a greater extent, the benefit loss of the operator is further reduced, and the benefit of the operator is further protected.

In an alternative embodiment, as shown in fig. 5, the determining the corresponding discount coefficient of the transaction amount based on the receiving time of the item receiving confirmation information of the target transaction sent by the user, the delivery time of the item delivery confirmation information of the target transaction sent by the operator, the expected transaction time and the predetermined request time comprises the following steps:

s501: based on the receipt time and the delivery time, a transaction completion time is obtained.

S502: and obtaining a target molecule based on a preset discount weight and a first time difference between the expected transaction time and the reservation request time.

S503: and taking a second time difference between the transaction completion time and the predetermined request time as a target denominator, and dividing the target numerator by the target denominator to determine the transaction amount discount coefficient.

For example, the step S501 may be, but is not limited to, taking an average time of the receiving time and the delivering time as the transaction completion time. It should be noted that, for the specific implementation manner of step S501, it can be determined by those skilled in the art according to practical situations, and the foregoing description is only an example, and is not limited thereto.

For example, the article reception confirmation information may be formed and sent by, but is not limited to, a user through a corresponding transaction application, a blockchain application, or a user node, for example, when the user clicks a receive confirmation button on the transaction application, the relevant control logic may capture the operation and automatically form and send the corresponding article reception confirmation information, or when the user clicks the receive confirmation button on the blockchain application, the relevant control logic may capture the operation and automatically form and send the corresponding article reception confirmation information through the corresponding user node. It should be noted that, the specific sending method of the article reception confirmation information can be determined by those skilled in the art according to actual situations, and the above description is only an example, and is not limited thereto.

For example, the article delivery confirmation information may be formed and sent by, but not limited to, the operator through the corresponding transaction application, the blockchain application, or the operator node, for example, when the operator clicks the confirmation delivery button on the transaction application, the relevant control logic may capture the operation and automatically form and send the corresponding article delivery confirmation information, or when the operator clicks the confirmation delivery button on the blockchain application, the relevant control logic may capture the operation and automatically form and send the corresponding article delivery confirmation information through the corresponding operator node. It should be noted that the specific sending method of the article delivery confirmation information can be determined by those skilled in the art according to actual situations, and the above description is only an example, and is not limited thereto.

Illustratively, the discount weight may be determined by those skilled in the art according to practical situations, and the embodiment of the present invention is not limited thereto. For example, the discount weight may be taken as a value in the range of (0,1 ], such as 0.95, 0.9 or 0.85, etc. preferably, when determining the discount weight, referring to the urgency (urgency) of the user's demand for the item, the more urgency the user's demand for the item, the smaller the discount weight, so as to fully consider the fact that the user demands the item for delivery by the urgent demand operator, if the operator delays delivery, the loss to the user will be greater than the loss when the user does not demand the item urgently, thereby facilitating the user to be compensated indirectly more by having the user pay less the relevant amount when the operator delays delivery and the user demands the item urgently.

For example, the step S502 may be, but is not limited to, multiplying the discount weight by the first time difference to obtain the target molecule. It should be noted that, for the specific implementation manner of step S502, it can be determined by those skilled in the art according to practical situations, and the foregoing description is only an example, and is not limited thereto.

Through the steps, the basis for measuring the delay degree of the delay delivery of the operator can be specifically refined to the corresponding time difference (the time difference respectively corresponds to the time for completing the actual transaction and the time for completing the expected transaction by taking the fixed predetermined request time as reference), so that the transaction amount discount coefficient can be specifically, quickly and accurately determined, and the transaction amount discount coefficient is corrected according to the actual situation and the demand through the discount weight, so that the transaction amount discount coefficient can be more fully combined with the related demand, and the extra influence condition of extra loss caused to the user due to the delay of the operator when the user has further demand (for example, the article is urgently needed) can be further accurately reflected on the basis of reflecting the delay condition of the operator. Therefore, the above steps can make the transaction amount discount coefficient more in line with the actual situation, so that the transaction amount discount coefficient can be improved to be negatively related to the delay degree of the operator, and further, when the delay of the operator is more serious, the amount of money required to be paid by the user is less, the loss compensation indirectly obtained by the user is more, and the protection degree of the benefits of the user is greatly improved.

In an optional embodiment, further comprising:

prior to dividing the target numerator by the target denominator,

Through the steps, when the operator makes a delivery in advance and does not make the delivery overdue, the user does not need to pay the fee exceeding the normal transaction amount (if the transaction amount discount coefficient is not made to be 1 when the target numerator is larger than the target denominator, the discount coefficient is made to be larger than 1, so that the user makes the payment in excess, economic loss is caused to the user), and the benefit of the user is further protected.

In an alternative embodiment, said deriving a transaction completion time based on said receipt time and delivery time comprises:

For example, the preset time difference threshold may be determined by a person skilled in the art according to actual situations, and for example, the preset time difference threshold may be, but is not limited to, 3 minutes or 5 minutes, etc.

When the difference between the receiving time and the delivery time is not obvious, the confirmation of the transaction ending time by the operator and the user is not obviously diverged, so that no matter whether the receiving time or the delivery time is selected as the transaction ending time for subsequent operation, the determined discount coefficients have no obvious deviation, and therefore, the steps can improve the speed of determining the transaction ending time by directly determining the transaction ending time on the basis of not influencing the accuracy of the determined transaction amount discount coefficients, so that the speed of overall transaction processing can be improved, and further the efficiency of the transaction is improved.

In an alternative embodiment of the method according to the invention, further comprising:

Through the steps, when the operator and the user have obvious divergence in the confirmation of the transaction ending time, the time for confirming the transaction by the user and the time for confirming the transaction by the operator are further deeply considered to carry out deeper balance, so that the confirmed transaction finishing time is as far as possible consistent with the time for actually finishing the delivery, the influence of negative factors which are possibly unreal by the time for confirming the transaction provided by a single party is further favorably reduced, the consistency degree of the transaction amount discount coefficient and the real delayed delivery condition of the operator is further favorably improved, the accuracy of the transaction amount discount coefficient is further improved, and the benefit of the user is further favorably protected.

In an optional embodiment, the deducting the transaction from the user based on the transaction amount discount coefficient, the transaction item information and the deposit amount includes:

subtracting the money amount from the total price of the transaction article corresponding to the transaction article information to obtain an initial amount to be paid;

For example, based on the amount to be paid, the specific principle of performing the transaction deduction on the user may refer to the description of the step of performing the deposit deduction on the user based on the deposit amount in the embodiment of the present invention, and details are not described here.

Through the steps, the amount to be paid can be accurately and clearly calculated according to the specific total price of the transaction items and the amount of the pre-paid deposit, so that the amount to be paid can accurately represent the amount of money to be paid except the deposit, the accuracy of the final amount to be paid obtained based on the amount to be paid is improved, the accuracy of transaction deduction is improved, and the smooth proceeding of the offline transaction is further promoted.
