Based on the above terminal device, various embodiments of the supply chain system management method based on blockchain are provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a blockchain-based supply chain system management method according to the present invention. It should be noted that although a logical order is depicted in the flowchart, in some cases the blockchain-based supply chain system management method of the present invention may of course perform the steps depicted or described in a different order than that depicted.
In a first embodiment of the blockchain-based supply chain system management method of the present invention, the blockchain-based supply chain system management method of the present invention includes:
step S10, obtaining transaction information to be verified, and determining a first number based on the geographic position of a supply chain participant corresponding to the transaction information, wherein the first number is the number of consensus nodes participating in the current consensus;
in this embodiment, the terminal device obtains transaction information to be verified, and determines the number of consensus nodes participating in the present consensus (hereinafter referred to as a first number to show distinction) based on the geographic position of the supply chain participant corresponding to the transaction information.
Further, in a possible embodiment, in the step S10, the step of determining the first number based on the geographic location of the supply chain participant corresponding to the transaction information may include: step S101, detecting whether a supply chain participant is in a single geographic area or not based on the geographic position of the supply chain participant corresponding to the transaction information;
in this embodiment, the terminal device detects whether the supply chain participant initiating the current transaction is in a single geographical area based on the geographical location to which the supply chain participant corresponds to the transaction information to be verified.
Illustratively, the geographic scope in which the present supply chain resides is divided into a plurality of geographic areas in advance, and the geographic location in which the supply chain participant node initiating the current transaction resides is detected as belonging to a single geographic area or a plurality of geographic areas.
Step S102, if the supply chain participants are detected to be in a single geographic area, taking the preset quantity as a first quantity;
in this embodiment, if the terminal device detects that the supply chain participant is in a single geographic area, the preset number is taken as the first number.
It should be noted that, based on different design requirements of practical applications, in different possible embodiments, the preset number may be any value meeting practical requirements, and the present invention is not limited to the specific size of the preset threshold number.
Step S103, if it is detected that the supply chain participant is in a plurality of geographical areas, determining the number of areas of the geographical area in which the supply chain participant is located, and calculating the first number based on the preset number and the number of areas.
In this embodiment, if the terminal device detects that the supply chain participant initiating the current transaction is in a plurality of geographical areas, determining the area number of the geographical areas in which the supply chain participant is located, and calculating the first number based on the preset number and the area number.
For example, when the terminal device detects that the number of the supply chain participating nodes initiating the current transaction is 3 and detects that the 3 participating nodes are respectively distributed in different geographical areas, the number of the geographical areas where the participating nodes are located may be determined to be 3, and assuming that the preset number is 30, the first number is 90, that is, the number of the areas corresponding to the participating nodes is in a proportional relation with the first number.
Step S20, determining the second number of sub-users selected randomly in each consensus node of the blockchain, and mapping the second number into a weight value when the consensus node participates in consensus;
in this embodiment, the terminal device determines the number of sub-users (hereinafter referred to as the second number to illustrate distinction) that are randomly selected in each consensus node of the blockchain, and maps the second number to a weight value when the consensus node participates in consensus.
The terminal device models the weight value of the consensus node as the number of sub-users, specifically, randomly selects a plurality of sub-users from the sub-users of each consensus node, and takes the number of the sub-users selected in each consensus node as the weight value of the consensus node when participating in the consensus voting.
For example, when each consensus node is selected, for the consensus node with the weight of w, the number of sub-users owned by the consensus node is w, and the number of sub-users selected by using the sub-user selection algorithm each time in a specific step of the consensus algorithm may be a value of 0,1,2, …, w, the number of the selected sub-users of the consensus node represents the voting weight owned by the consensus node in the consensus step, that is, if the number of the selected sub-users is 0, the consensus node is not selected in the current consensus step; when the number of selected sub-users is i, representing that the consensus node transmits voting information once in the current consensus step, the consensus node sums the voting number to be i in the current consensus step. Specifically, if a consensus node with a weight value of 100 in one selection has 5 sub-users selected, the consensus node sends a voting message every time in the consensus step, which indicates that the node actually sums up to 5 votes in the consensus step, and so on.
Step S30, selecting the first number of consensus nodes from the consensus nodes as target consensus nodes participating in the current consensus based on the weight values and the reputation values of the consensus nodes;
in this embodiment, the terminal device selects, based on the weight values and the reputation values of the consensus nodes, a first number of consensus nodes from the consensus nodes as target consensus nodes participating in the present consensus.
Further, in a possible embodiment, the step S30 may include:
step S301, selecting the first number of second consensus nodes from the consensus nodes based on the weight values;
in this embodiment, the terminal device selects a first number of consensus nodes (hereinafter referred to as second consensus nodes to show distinction) from the consensus nodes based on the weight values corresponding to the consensus nodes.
Further, in a possible embodiment, the step S301 may include:
step A10, selecting a plurality of maximum target weight values from the weight values based on the magnitude relation among the weight values, wherein the number of the target weight values is the first number;
And step A20, taking the consensus node corresponding to each target weight value as a second consensus node.
In this embodiment, the terminal device selects, based on the magnitude relation between the weight values, a plurality of maximum target weight values from the weight values, where the number of the target weight values is equal to the first number, and uses the consensus node corresponding to each target weight value as the second consensus node.
For example, assuming that the first number is 30, after determining the weight values corresponding to the consensus nodes, the weight values are ordered according to a rule from big to small, the weight value arranged in the first 30 bits is determined as a target weight value, and the consensus node corresponding to each of the 30 target weight values is taken as the first consensus node.
Step S302, detecting whether the reputation value of the second consensus node is larger than a preset threshold value or not based on the reputation value of each consensus node;
in this embodiment, the terminal device detects whether the reputation value of the second consensus node is greater than a preset threshold based on the reputation value of each consensus node.
It should be noted that, a behavior record table corresponding to all consensus nodes in the blockchain is pre-established, the behavior record table records node credits commonly maintained by all nodes in the supply chain, and each node can be classified into a good node, an intermediate node and a malicious node according to the node credits.
For example, the terminal device sequentially detects whether reputation values corresponding to the first 30 second consensus nodes with weight values arranged in the first 30 are greater than a preset threshold.
Step S303, if the reputation value of the second consensus node is detected to be larger than the preset threshold value, the second consensus node is used as a target consensus node participating in the current consensus;
in this embodiment, if the terminal device detects that the reputation value of the second consensus node is greater than the preset threshold, the second consensus node is used as the target consensus node participating in the current consensus.
For example, if the terminal device detects that the reputation values of the 30 second consensus nodes are all greater than the preset threshold, the current 30 second consensus nodes are used as target consensus nodes participating in the current consensus.
Step S304, if the reputation value of the second consensus node is detected to be less than or equal to the preset threshold, replacing the second consensus node with a third consensus node with the largest reputation value in the remaining nodes, and taking the third consensus node as the target consensus node, wherein the remaining nodes are other consensus nodes except the second consensus node in the consensus nodes.
In this embodiment, if the terminal device detects that the reputation value of the second consensus node is less than or equal to the preset threshold, the terminal device replaces the second consensus node with the highest reputation value among the remaining nodes (hereinafter referred to as the third consensus node to show the distinction), and takes the third consensus node as the target consensus node, where the remaining nodes are other consensus nodes except the second consensus node among the remaining nodes.
If the terminal device detects that the reputation value of 4 consensus nodes in the 30 second consensus nodes is smaller than the preset threshold value, 4 consensus nodes with highest reputation values are selected from the other consensus nodes except the 30 consensus nodes, namely the third consensus node, the third consensus node is used for replacing the 4 consensus nodes with reputation values smaller than the preset threshold value, and the third consensus node is used as a target consensus node participating in the current consensus.
And step S40, verifying the transaction message through the target consensus node to obtain a verification result.
In this embodiment, the terminal device verifies the transaction message through the target consensus node, and a verification result is obtained.
Illustratively, after 30 target consensus nodes are selected, each target consensus node votes for the current transaction information, and if the target consensus node exceeding 2 of 3 agrees to the current transaction information, the verification result is determined to be verification passing.
Further, in a possible embodiment, after the step S40, the method may further include:
and B10, when the verification result is verification passing, the transaction information is counted into a blockchain account book, and the reputation value of the target consensus node is updated based on the verification result.
In this embodiment, when the verification result of the current transaction information is verification passing, the terminal device counts the transaction information into the blockchain ledger, and updates the reputation value of the target consensus node based on the verification result.
As shown in fig. 3, the terminal device first determines the geographical area where the initiator of the transaction information to be verified is located, determines the number of consensus nodes required for the current consensus based on the geographical area, then selects the required number of target consensus nodes based on the weight value and the reputation value of each consensus node in the blockchain, verifies the current transaction information by a plurality of target consensus nodes to obtain a verification result, counts the transaction information into the blockchain ledger, broadcasts the blockchain after the verification result of the current transaction information is verification pass, adds 1 to the reputation value of the target consensus node agreeing to the current transaction information, subtracts 1 to the reputation value of the target consensus node against the current transaction information, and in addition, keeps the reputation value of the target consensus node successfully sending the voting message unchanged.
In the embodiment, the supply chain system management method based on the blockchain acquires transaction information to be verified, and determines the first number of consensus nodes participating in the consensus based on the geographic position of a supply chain participant corresponding to the transaction information; detecting whether a supply chain participant initiating a current transaction is in a single geographic region or not based on the geographic position of the supply chain participant corresponding to the transaction information to be verified; if the supply chain participants are detected to be in a single geographic area, taking the preset quantity as a first quantity; if the supply chain participant initiating the current transaction is detected to be in a plurality of geographic areas, determining the area number of the geographic areas in which the supply chain participant is located, and calculating the first number based on the preset number and the area number; determining the second number of sub-users selected randomly in each consensus node of the block chain, and mapping the second number into a weight value when the consensus node participates in consensus; selecting a plurality of maximum target weight values from the weight values based on the magnitude relation among the weight values, wherein the number of the target weight values is equal to the first number, and the consensus nodes corresponding to the target weight values are used as second consensus nodes; detecting whether the reputation value of the second consensus node is larger than a preset threshold value or not based on the reputation value of each consensus node; if the reputation value of the second consensus node is detected to be larger than the preset threshold value, the second consensus node is used as a target consensus node participating in the current consensus; if the reputation value of the second consensus node is detected to be smaller than or equal to a preset threshold value, replacing the second consensus node with a third consensus node with the highest reputation value in the rest nodes, and taking the third consensus node as a target consensus node, wherein the rest nodes are other consensus nodes except the second consensus node in all the consensus nodes; verifying the transaction message through the target consensus node to obtain a verification result; and when the verification result of the current transaction information is verification passing, the transaction information is counted into a blockchain account book, and the reputation value of the target consensus node is updated based on the verification result.
In this way, the embodiment of the invention determines the number of the consensus nodes participating in the current consensus based on the geographic position of the supply chain participant corresponding to the transaction information, namely the first number, then determines the number of the sub-users randomly selected from the consensus nodes of the block chain, namely the second number, maps the second number to the weight value when the consensus nodes participate in the consensus, selects the first number of the consensus nodes from the consensus nodes based on the weight value and the reputation value corresponding to the consensus nodes as the target consensus nodes participating in the current consensus, and finally verifies the transaction information through the target consensus nodes to obtain the verification result. Therefore, the invention improves the authenticity and accuracy of the transaction information among all the participants in the supply chain by determining the number of the nodes participating in the consensus based on the geographic position of the transaction initiator and determining the final consensus node participating in the current consensus based on the weight value and the credit value of each consensus node in the blockchain.
Further, based on the first embodiment of the blockchain-based supply chain system management method of the present invention described above, a second embodiment of the blockchain-based supply chain system management method of the present invention is presented.
In this embodiment, in step S20, the step of "determining the second number of sub-users each randomly selected in each consensus node of the blockchain" may include:
step S201, generating a random number based on the verifiable random function;
step S202, calculating a random probability value corresponding to the random number based on the byte length of the random number;
step S203, determining a second number of randomly selected sub-users in a first consensus node according to the random probability value, where the first consensus node is any one of the consensus nodes of the blockchain.
In this embodiment, the terminal device generates a random number based on a verifiable random function, calculates a random probability value corresponding to the random number based on a byte length of the random number, and then determines a second number of randomly selected sub-users in a first consensus node according to the random probability value, where the first consensus node is any one of the consensus nodes of the blockchain.
In the process of selecting the consensus node, when the random number selection algorithm generates a random number, a corresponding probability value can be obtained by calculating the random number, specifically, the probability value is:
Then, the number of randomly selected sub-users in the consensus node is determined based on the probability value. Further, in a possible embodiment, the step S203 may include:
step C10, determining a probability distribution interval where the random probability value is located according to the random probability value;
and step C20, determining a second number of randomly selected sub-users in the first consensus node based on the probability distribution interval and the cumulative distribution curve of binomial distribution.
In this embodiment, the terminal device determines a probability distribution interval in which the random probability value is located according to the random probability value, and determines the second number of randomly selected sub-users in the first consensus node based on the probability distribution interval and a cumulative distribution curve of binomial distribution.
Illustratively, the binomial distribution cumulative distribution curve corresponds to a graph of a binomial distribution cumulative distribution function. For the consensus node with weight w, the number of the sub-users owned by the consensus node is w, and the consensus node is in a specific step of the consensus algorithmThe number of sub-users selected each time using the sub-user selection algorithm may be a value of one of 0,1,2, …, w. Assuming that the sum of weight values selected by all participating consensus nodes is w, and the expected number of node sub-users to be selected in a specific consensus step is e, wherein the expected probability value can be used for calculating the probability that any one sub-user of any consensus node is selected, and the probability that any one sub-user of any consensus node is selected is:
And the probability that m sub-users of the consensus node are selected isHere->Representing the number of combinations of m sub-users selected from the w sub-users. Thereby, on the cumulative distribution curve of the binomial distribution selected by the corresponding child user, the probability interval [0,1 ] on the vertical axis]Can be divided into->And the remaining series interval +> ). And then, determining the number of the sub-users selected by the consensus node by checking which interval in the probability interval division the probability value is located. Specifically, if the probability value is located +.>In the interval, the number of the sub-users selected by the consensus node is 6, and so on.
In the embodiment, the supply chain system management method based on the block chain generates a random number based on a verifiable random function, and calculates a random probability value corresponding to the random number based on the byte length of the random number; and determining a probability distribution interval where the random probability value is located according to the random probability value, and determining a second number of randomly selected sub-users in the first consensus node based on the probability distribution interval and a binomial distribution cumulative distribution curve.
Therefore, the number of the selected sub-users is determined by randomly selecting the sub-users in the consensus node, so that the weight value of the consensus node, the probability of the consensus node being selected to participate in the operation of the consensus algorithm and the voting weight of the consensus node after being selected are reflected, and the randomness and fairness of the selection of the consensus node are greatly improved.
