The memory 1005 may also optionally be a storage device separate from the processor 1001 described above.
It will be appreciated by those skilled in the art that the structure shown in fig. 1 does not constitute a limitation of the terminal device, and may include more or less components than illustrated, or may combine certain components, or may be arranged in different components.
As shown in fig. 1, the memory 1005, which is a storage medium, may include an operating system, a data storage module, a network communication module, a user interface module, and a program for constructing a consensus scheme.
In the terminal device shown in fig. 1, the network interface 1004 is mainly used for data communication with other devices; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the terminal device of the present invention may be provided in the terminal device, and the terminal device calls the construction program of the consensus scheme stored in the memory 1005 through the processor 1001 and executes the construction method of the consensus scheme provided by the embodiment of the present invention.
Based on the above terminal device, various embodiments of the construction method of the consensus scheme of the present invention are provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a method for constructing a consensus scheme according to the present invention.
It will be appreciated that although a logical order is depicted in the flowchart, in some cases the method of construction of the consensus scheme of the present invention may of course also be performed in an order different from that depicted or described herein.
In this embodiment, the method for constructing the consensus scheme of the present invention may include:
step S10: determining each target candidate node in the initial block chain based on the node reputation value corresponding to each node in the initial block chain and a preset reputation value threshold;
in this embodiment, when running, the terminal device first reads the storage module to obtain a reputation value threshold stored in advance by the developer, and at the same time, the terminal device reads node reputation values corresponding to each initial node in the initial blockchain, and sequentially compares each node reputation value with the reputation value threshold, so as to determine a plurality of target candidate authoritative nodes in each initial node.
For example, the terminal device receives a data packet including an initial blockchain and a reputation value threshold sent by a developer in the development terminal in advance and stores the initial blockchain and the reputation value threshold carried in the data packet in a storage module, then, in the operation process, the terminal device firstly reads the storage module to obtain the blockchain and the reputation value threshold and determine the value corresponding to the reputation value threshold, and the terminal device reads the node reputation value corresponding to each initial node in the initial blockchain and inputs each node reputation value to a data comparison device built in the terminal device, and the data comparison device compares each node reputation value with the reputation value threshold to determine a plurality of candidate authoritative nodes in each node.
It may be understood that in this embodiment, the node reputation value is a comprehensive value obtained by calculating, according to a preset reputation parameter weight ratio, data such as each transaction behavior record, transaction duration, each transaction amount, total value of a transaction account and the like generated by performing transactions in each other block chain before performing the transactions on the user account corresponding to the initial node, where the comprehensive value further represents the reputation of the user account, and according to different transaction scenarios, a developer may also change the reputation parameter weight ratio and other reputation reference data.
Further, in a possible embodiment, the step S10 may specifically include:
step S101: acquiring node reputation values corresponding to all initial nodes in the initial block chain;
in this embodiment, the terminal device extracts the node reputation values corresponding to the initial nodes in the initial blockchain, and inputs the node reputation values to the data comparison module built in the terminal device.
Step S102: comparing the node reputation values with preset reputation value thresholds respectively to determine target reputation values which are larger than the reputation value thresholds in the node reputation values;
In this embodiment, the terminal device sequentially compares the reputation value of each initial node with the reputation value threshold through the data comparison module to determine whether the reputation value of the node is greater than the reputation value threshold, and further determines, in each node reputation value, a reputation value of each target node greater than the reputation value threshold.
Step S103: determining the initial node corresponding to each target reputation value as a target candidate node;
in this embodiment, the terminal device determines initial nodes corresponding to the reputation values of the target nodes, and marks each initial node as the target candidate node.
For example, the terminal device extracts a node reputation value corresponding to the initial node 1 in the initial blockchain to be 70, and a node reputation value corresponding to the initial node 2 to be 76.
It should be noted that, in this embodiment, the reputation value threshold may be set freely based on the application scenario of the initial blockchain, or set by the developer according to the requirement, which is not limited by the method of constructing the consensus scheme of the present invention.
Further, in a possible embodiment, before the step S10, the method for constructing the consensus scheme of the present invention may specifically further include:
step A10: acquiring a preset authority proof consensus algorithm;
in this embodiment, the terminal device reads the storage module to acquire the authority-proof consensus algorithm stored in advance by the developer.
Step A20: constructing an initial blockchain based on the authority proof consensus algorithm;
in this embodiment, the terminal device inputs the obtained authority-proof consensus algorithm to a blockchain construction module built in the terminal device, and the blockchain construction module constructs the initial blockchain based on the authority-proof consensus algorithm.
For example, the terminal device reads the storage module to obtain the POA consensus algorithm stored in advance by the developer, and inputs the POA consensus algorithm to the built-in blockchain building module of the terminal device, the blockchain building module uses the POA consensus algorithm as the consensus mechanism of the initial blockchain, and the blockchain building module reads the core application components such as the preset other programmable contracts, programmable assets, and incentive mechanisms to build the initial blockchain.
In this embodiment, besides the POA consensus algorithm, the developer may select the rest of the consensus algorithm with reference to the user reputation or the reference user reputation as the consensus base.
Step S20: randomly determining each initial authority node in each target candidate node, and setting the weight value of each initial authority node as a preset first weight value;
in this embodiment, the terminal device inputs the target candidate nodes to a node screening module built in the terminal device, the node screening module randomly selects a plurality of nodes in the target candidate nodes as initial authority nodes, and meanwhile, the terminal device reads the storage module to obtain a first weight value stored in advance by a developer, and the terminal device sets the weight value corresponding to the initial authority node as the first weight value.
For example, referring to fig. 4, fig. 4 is a schematic node screening diagram related to a first embodiment of a method for constructing a consensus scheme of the present invention, a terminal device reads a storage module in advance to obtain the number of authoritative nodes and a first weight value stored in advance by a developer, and meanwhile, the terminal device inputs each obtained target candidate node to a node screening module built in the terminal device, the node screening module randomly selects a target candidate node corresponding to the number of authoritative nodes from each target candidate node, determines each selected target candidate node as the initial authoritative node, and then the terminal device sets each initial authoritative node according to the first weight value to make the weight value corresponding to the initial authoritative node be the first weight value.
It may be understood that in this embodiment, when the number of the authoritative nodes is 4 and the first weight value is 3, it indicates that the terminal device screens 4 target candidate nodes from all target candidate nodes as initial authoritative nodes, and determines the weight value corresponding to the initial authoritative nodes as 3, so that, when the number of the authoritative nodes is smaller than the number of the candidate nodes, a developer may set the number of the authoritative nodes and the first weight value at will, and the construction method of the consensus scheme of the present invention is not limited thereto.
Step S30: randomly determining each initial non-authoritative node in each non-target candidate node except each target candidate node, and setting the weight value of each initial non-authoritative node as a preset second weight value;
in this embodiment, the terminal device inputs all the initial nodes except for the target candidate nodes in the initial blockchain to a node screening module built in the terminal device, the node screening module randomly selects a plurality of initial nodes from all the initial nodes as initial non-authoritative nodes, and meanwhile, the terminal device reads the storage module to obtain a second weight value stored in advance by a developer, and the terminal device sets the weight value corresponding to the initial non-authoritative node as the second weight value.
For example, referring to fig. 4, the terminal device reads the storage module in advance to obtain the number of non-authoritative nodes and the second weight value stored in advance by the developer, when the number of the initial non-authoritative nodes is 7 and the second weight value is 1, the terminal device inputs the rest initial nodes except for each target candidate node in the initial blockchain to the node screening module, the node screening module screens 7 initial nodes from the initial nodes as initial non-authoritative nodes, and then the terminal device sets the weight value corresponding to the initial non-authoritative nodes to be 1 according to the second weight value.
It may be understood that in this embodiment, the terminal device may further input, to the node screening module, each of the remaining initial nodes except for each of the initial authoritative nodes in the initial blockchain to obtain each of the initial non-authoritative nodes, and when the number of the non-authoritative nodes is smaller than the number of the remaining initial nodes except for each of the target candidate nodes, the developer may optionally adjust the number of the non-authoritative nodes and the second weight value, where the second weight value is smaller than the first weight value.
Step S40: inputting each initial authoritative node, the first weight value, each initial non-authoritative node and the second weight value into a preset target consensus function to construct a target consensus scheme;
in this embodiment, the terminal device inputs the obtained initial authority nodes, the first weight value, the initial non-authority nodes and the second weight value to a scheme construction module built in the terminal device, and the scheme construction module invokes a target consensus function preset by a developer to construct the target consensus scheme based on the initial authority nodes, the first weight value, the initial non-authority nodes and the second weight value.
Further, in a possible embodiment, the step S40 may specifically include:
step S401: inputting each initial authoritative node, the first weight value, each initial non-authoritative node and the second weight value into a preset target consensus function, combining each initial authoritative node with the first weight value by the target consensus function, and combining each initial non-authoritative node with the second weight value to construct a target consensus scheme;
For example, the terminal device inputs the obtained initial authority nodes X1, X2, X3, XN, the initial non-authority nodes Y1, Y2, Y3, YN, the first weight value 3, and the second weight value 1 to the scheme building module, the scheme building module invokes a target consensus function preset by the developer to combine the initial authority nodes X1, X2, X3, XN and the first weight value 3, respectively, while the target consensus function combines the non-authority nodes Y1, Y2, Y3, respectively, YN and the second weight value 1 to obtain a target consensus function Σ (x×3) +Σ (y×1) after each value is taken in, and the scheme building module builds an RPOA consensus scheme as the target consensus scheme based on the target function Σ (x×3) +Σ (y×1).
In this embodiment, when running, a terminal device first reads a storage module to obtain a reputation value threshold value pre-stored by a developer, and at the same time, the terminal device reads a node reputation value corresponding to each initial node in an initial block chain, and sequentially compares each node reputation value with the reputation value threshold value to determine a plurality of target candidate authoritative nodes in each initial node, then the terminal device inputs each target candidate node into a node screening module built in the terminal device, the node screening module randomly selects a plurality of nodes in each target candidate node as initial authoritative nodes, and at the same time, the terminal device reads the storage module to obtain a first weight value pre-stored by the developer, the terminal device sets a weight value corresponding to the initial authoritative node as the first weight value, then the terminal device inputs all initial nodes except for each target candidate node in the initial block chain into the node screening module built in the terminal device, the node screening module randomly selects a plurality of initial nodes in each initial authoritative nodes as initial non-nodes, and at the same time, the terminal device reads a first weight value corresponding to the initial weight value pre-stored by the developer, and the terminal device sets a second weight value corresponding to the first weight value, and the terminal device calls a second weight value corresponding to the first weight value, and the terminal device sets a second weight value corresponding to the initial value, and the first weight value is built up a second weight value corresponding to the initial value, each of the initial non-authoritative nodes and the second weight value construct the target consensus scheme.
In this way, the invention adopts the mode of determining each initial authoritative node and each initial non-authoritative node in each initial node in the initial block chain based on the reputation value, respectively setting corresponding first weight value and second weight value for each initial authoritative node and each initial non-authoritative node, and finally determining the target consensus scheme based on each initial authoritative node, the first weight value, each initial non-authoritative node and the second weight value, thereby achieving the technical effects that the built target consensus scheme can realize decentralization, and the scheme is safer and can be applied to the public block chain.
Further, based on the first embodiment of the construction method of the consensus scheme of the present invention described above, a second embodiment of the construction method of the consensus scheme of the present invention is presented herein.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of a method for constructing a consensus scheme according to the present invention.
Based on the first embodiment of the construction method of the consensus scheme of the present invention shown in fig. 2, after the step S40, the construction method of the consensus scheme of the present invention may further include:
step B10: constructing a target blockchain based on the target consensus scheme, and detecting the target blockchain to determine whether transaction data is generated in the target blockchain;
In this embodiment, the terminal device inputs the obtained target consensus scheme to a blockchain construction module set in the terminal device, and the blockchain construction module constructs a target blockchain based on the target consensus scheme and other preset core application components such as programmable contracts, programmable assets, and an incentive mechanism, and meanwhile, the terminal device detects the target blockchain through a built-in data detection module to determine whether transaction data is generated between each target node in the target blockchain.
Step B20: if yes, calculating the transaction data through all target authority nodes in the target block chain to obtain all target calculation results, wherein the target authority nodes are nodes with transaction verification authorities selected by all nodes of the target block chain based on the target consensus scheme;
in this embodiment, if the terminal device detects that transaction data is generated between the target nodes in the target blockchain, the terminal device acquires the transaction data, invokes each target authority node selected by each target node in the target blockchain based on the identification scheme to calculate the transaction data together, and generates a corresponding calculation result.
Step B30: determining a transaction confirmation result corresponding to each target calculation result based on the target consensus scheme;
in this embodiment, the terminal device distributes the calculation result to each target authoritative node and each target non-authoritative node in the target blockchain, and determines a transaction confirmation result corresponding to the calculation result based on a first weight value corresponding to the target authoritative node and a second weight value corresponding to the target non-authoritative node included in the target consensus scheme.
For example, the terminal device inputs the obtained target RPOA consensus scheme to a blockchain construction module arranged in the terminal device, the blockchain construction module uses the RPOA consensus scheme as a consensus mechanism, and invokes other core application components such as programmable contracts, programmable assets, and incentive mechanisms to construct the target blockchain, meanwhile, the terminal device detects the transaction behaviors of each target node in the target blockchain through a built-in data detection module to determine whether each target node generates transaction data, when the terminal device detects that digital transaction is performed between a target node X and a target node Y in the target blockchain through the target blockchain, the terminal device obtains the transaction data generated by the digital transaction, inputting the transaction data to each target authority node in the target blockchain determined based on the RPOA consensus scheme, obtaining a target calculation result by each target authority node based on the transaction data, generating a transaction confirmation result corresponding to the target calculation result, then distributing the transaction confirmation result to each target authority node X1, X2, X3,..2, XN and each target non-authority node Y1, Y2, Y3, & gt, YN in the target blockchain by the terminal equipment, simultaneously, reading a first weight value 3 corresponding to the target authority node, a second weight value 1 corresponding to each target non-authority node by the terminal equipment, determining a first transaction confirmation result corresponding to each target authority node and a second transaction confirmation result corresponding to each target non-authority node based on a target consensus function carried in the RPOA consensus scheme, and finally, the terminal device determines a final transaction confirmation result based on the different weights.
It should be noted that, in this embodiment, if the first transaction confirmation result corresponding to each target authority node is inconsistent with the second transaction confirmation result corresponding to each target non-authority node, and the first confirmation weight value corresponding to the first transaction confirmation result is consistent with the second confirmation weight value corresponding to the second transaction confirmation result, the terminal device determines that the transaction data is invalid data.
Further, in a possible embodiment, before the step B30, the construction of the consensus scheme of the present invention may specifically further include:
step C10: verifying each target calculation result to determine whether each target calculation result contains a target error calculation result or not;
in this embodiment, after detecting that each target authority node in the target blockchain calculates to obtain a calculation result, the terminal device inputs each calculation result to a data comparison module, and the data comparison module determines whether each calculation result includes a target error calculation result.
Step C20: and if the target calculation results contain the target error calculation results, backtracking the transaction data to the moment of generating the transaction data.
In this embodiment, if the data comparison module in the terminal device determines that the calculation results include the target error calculation result, the terminal device backtracks the transaction data through the built-in data recording device, and backtracks the transaction data to the time when the target blockchain generates the transaction data.
For example, after detecting that each target authority node in the target blockchain calculates to obtain each calculation result, the terminal device inputs each calculation result to a data comparison module, and the data comparison module sequentially compares each calculation result with other calculation results to determine whether the calculation results are consistent, so as to determine whether a target error calculation result exists in each calculation result, and when detecting that the target error calculation result exists in each calculation result, the terminal device reads a built-in data recording device to determine transaction data corresponding to the transaction behavior and backtracks the transaction data to the moment when the target blockchain generates the transaction data.

Step D10: acquiring a preset node refreshing frequency;
in this embodiment, the terminal device reads the storage module to obtain the node refresh frequency preset by the developer.
Step D20: the target block chain is controlled to replace each target authority node according to the node refreshing frequency;
in this embodiment, the terminal device sets the target blockchain according to the node refresh frequency, so that the target blockchain randomly selects a new target authority node from the candidate nodes again according to the node refresh frequency pair.
For example, the terminal device reads the storage module to obtain the node refresh frequency stored in advance by the developer, determines that the node refresh frequency is 1h, and then sets the target blockchain to randomly select a plurality of target authoritative nodes in each candidate node based on the RPOA consensus scheme every 1 h.
In this embodiment, the terminal device inputs the obtained target consensus scheme to a blockchain construction module set in the terminal device, the blockchain construction module constructs a target blockchain based on the target consensus scheme and other preset core application components such as programmable contracts, programmable assets and excitation mechanisms, and meanwhile, the terminal device detects the target blockchain through a built-in data detection module to determine whether transaction data are generated between target nodes in the target blockchain, and then, if the terminal device detects that transaction data are generated between target nodes in the target blockchain, the terminal device obtains the transaction data, invokes the target authority nodes selected by the target nodes in the target blockchain based on the identification scheme to jointly calculate the transaction data and generate corresponding calculation results, and finally, distributes the calculation results to the target authority nodes and the target non-authority nodes in the target blockchain, and determines a transaction confirmation result based on a first weight value corresponding to the target authority node and a second calculation result corresponding to the target non-authority node included in the target consensus scheme.
In this way, the invention adopts the mode of constructing the target block chain based on the target consensus scheme, and when transaction data is generated in the target block chain, all target authority nodes in the target block chain jointly calculate the calculation result corresponding to the transaction data, and all target authority nodes and all target non-authority nodes in the target block chain jointly determine the transaction confirmation result corresponding to the calculation result, thereby achieving the purposes of ensuring relatively fair and fair transaction confirmation result and reducing the centralization of the target consensus scheme.
