The network interface 1004 may optionally include a standard wired interface, a WIreless interface (e.g., a WIreless-FIdelity (WI-FI) interface). The Memory 1005 may be a Random Access Memory (RAM) Memory, or may be a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the terminal device and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, the memory 1005, which is a storage medium, may include therein an operating system, a data storage module, a network communication module, a user interface module, and a construction program of 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 disposed 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 terminal device, various embodiments of the construction method of the consensus scheme are provided.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a method for constructing a consensus scheme according to the present invention.
It is to be understood that while a logical order is shown in the flow chart, in some cases the method of constructing a consensus of the present invention may, of course, perform the steps shown or described in a different order than here.
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 a node reputation value corresponding to each node in the initial block chain and a preset reputation value threshold;
in this embodiment, when the terminal device operates, the terminal device first reads the 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 the initial block chain, and compares each node reputation value with the reputation value threshold value in sequence to determine a plurality of target candidate authoritative nodes in each initial node.
For example, the terminal device receives a data packet sent by a developer at a development terminal in advance, the data packet includes an initial block chain and a reputation value threshold, and stores the initial block chain and the reputation value threshold carried in the data packet in a storage module, then, during operation, the terminal device first reads the storage module to obtain the block chain and the reputation value threshold and determines a value corresponding to the reputation value threshold, the terminal device reads a node reputation value corresponding to each initial node in the initial block chain 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 reputation nodes in each node.
It can be understood that, in this embodiment, the node reputation value is a comprehensive value obtained by calculating data such as transaction behavior records, transaction duration, transaction amounts, total transaction account values and the like generated by performing transactions in other block chains before the user account corresponding to the initial node according to a preset reputation parameter weight ratio, and the comprehensive value further represents the reputation of the user account.
Further, in a possible embodiment, the step S10 may specifically include:
step S101: acquiring a node reputation value corresponding to each initial node in an initial block chain;
in this embodiment, the terminal device extracts the node reputation value corresponding to each initial node in the initial block chain, and inputs the node reputation value to the data comparison module built in the terminal device.
Step S102: comparing each node reputation value with a preset reputation value threshold value respectively to determine each target reputation value which is greater than the reputation value threshold value in each node reputation value;
in this embodiment, the terminal device compares each initial node reputation value with the reputation value threshold value in sequence through the data comparison module to determine whether the node reputation value is greater than the reputation value threshold value and then determine each target node reputation value greater than the reputation value threshold value in each node reputation value.
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 the initial nodes as the target candidate nodes.
Illustratively, for example, the terminal device extracts a node reputation value corresponding to the initial node 1 in the initial block chain to be 70, and a node reputation value corresponding to the initial node 2 to be 76, so that the terminal device sequentially extracts respective node reputation values of the initial nodes in the initial block chain, inputs the extracted respective node reputation values into a data comparison module built in the terminal device, and then the data comparison module reads the values of the reputation value thresholds and compares the respective node reputation values with the reputation value thresholds in sequence, when the reputation value thresholds are preset to be 90 by the developer, the data comparison module determines respective target node reputation values with values larger than 90 in the respective node reputation values, and the terminal device further determines the initial nodes corresponding to the target node reputation values and determines respective numbers corresponding to the initial nodes, and then marks the initial nodes as the candidate nodes.
It should be noted that, in this embodiment, the reputation value threshold may be freely set based on an application scenario of an initial block chain, or may be set by a developer according to a requirement, which is not limited by the construction method of 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 further include:
step A10: acquiring a preset authority certificate consensus algorithm;
in this embodiment, the terminal device reads the storage module to obtain an authority certificate consensus algorithm pre-stored by the developer.
Step A20: constructing an initial block chain based on the authority certification consensus algorithm;
in this embodiment, the terminal device inputs the obtained authority certificate consensus algorithm to a block chain building module built in the terminal device, and the block chain building module builds the initial block chain based on the authority certificate consensus algorithm.
Illustratively, for example, the terminal device reads the storage module to obtain a POA consensus algorithm pre-stored by a developer, and inputs the POA consensus algorithm into a block chain building module built in the terminal device, and the block chain building module uses the POA consensus algorithm as a consensus mechanism of the initial block chain, and simultaneously reads core application components such as other preset programmable contracts, programmable assets, and incentive mechanisms to build the initial block chain.
It should be noted that, in this embodiment, besides the above-mentioned POA consensus algorithm, the developer may also select the rest of reference user reputations or the reference user reputation as the consensus algorithm based on the consensus.
Step S20: randomly determining each initial authoritative node in each target candidate node, and setting the weight value of each initial authoritative 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 authoritative nodes, meanwhile, the terminal device reads a storage module to obtain a first weight value pre-stored by a developer, and the terminal device sets the weight value corresponding to the initial authoritative 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 according to the present invention, where a terminal device reads a storage module in advance to obtain a number of authoritative nodes and a first weight value stored by a developer in advance, and at the same time, the terminal device inputs each obtained target candidate node to a node screening module built in the terminal device, and the node screening module randomly selects a target candidate node corresponding to the number of authoritative nodes from each target candidate node, and 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 so that a weight value corresponding to an initial authoritative node is the first weight value.
It can be understood that, in this embodiment, when the number of the authority nodes is 4 and the first weight value is 3, it indicates that the terminal device filters 4 target candidate nodes from each target candidate node as initial authority nodes, and determines the weight value corresponding to the initial authority node as 3, so that, in a case where the number of the authority nodes is less than the number of the candidate nodes, a developer may arbitrarily set the number of the authority nodes and the first weight value, and the construction method of the consensus scheme of the present invention does not limit this.
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 each initial node in the initial block chain except for each target candidate node into a node screening module built in the terminal device, the node screening module randomly selects a plurality of initial nodes from each initial node as initial non-authoritative nodes, meanwhile, the terminal device reads a storage module to obtain a second weight value pre-stored 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, for example, the terminal device reads the storage module in advance to obtain the number of non-authoritative nodes and a 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 remaining initial nodes except for the target candidate nodes in the initial block chain to the node screening module, the node screening module screens 7 initial nodes in each initial node as initial non-authoritative nodes, and then the terminal device sets the weight value corresponding to the initial non-authoritative node to 1 according to the second weight value.
It is understood that, in this embodiment, the terminal device may further input each initial node except each initial authoritative node in the initial block chain to the node screening module to obtain each initial non-authoritative node, and when the number of the non-authoritative nodes is smaller than the number of the initial nodes except each target candidate node, the developer may arbitrarily adjust the number of the non-authoritative nodes and the second weight value, but the second weight value should be 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 authoritative nodes, the first weight value, the initial non-authoritative nodes and the second weight value into a scheme building module built in the terminal device, and the scheme building module calls a target consensus function preset by a developer to build the target consensus scheme based on the initial authoritative nodes, the first weight value, the initial non-authoritative 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 and the first weight value by the target consensus function, and combining each initial non-authoritative node and the second weight value to construct a target consensus scheme;
illustratively, for example, the terminal device inputs the obtained initial authoritative nodes X1, X2, X3.,. XN, the initial non-authoritative nodes Y1, Y2, Y3.,. YN, the first weight value 3 and the second weight value 1 into the scenario construction module, the scenario construction module calls a target consensus function preset by a developer to combine the initial authoritative nodes X1, X2, X3.,. XN with the first weight value 3, and the target consensus function combines the non-authoritative nodes Y1, Y2, Y3.,. YN with the second weight value 1, respectively, so as to obtain a target consensus function (X3) + Σ (Y × 1) which is substituted with the first weight value, and the scenario construction module constructs an rpconsensus scenario based on the target function (X3) + Σ (Y × oa 1).
In this embodiment, the terminal device first reads the storage module to obtain the reputation value threshold value pre-stored by the developer during operation, and at the same time, the terminal equipment reads the node reputation value corresponding to each initial node in the initial block chain, compares the node reputation value with the reputation value threshold value in sequence to determine a plurality of target candidate authoritative nodes in each initial node, and then, the terminal equipment inputs the target candidate nodes into a node screening module arranged in the terminal equipment, the node screening module randomly selects a plurality of nodes in the target candidate nodes as initial authoritative nodes, and simultaneously, the terminal device reads the storage module to obtain a first weight value pre-stored by a developer, sets the weight value corresponding to the initial authoritative node as the first weight value, and then, the terminal device inputs all the other initial nodes except the target candidate nodes in the initial block chain to a node screening module arranged in the terminal device, the node screening module randomly selects a plurality of initial nodes in all the initial nodes as initial non-authoritative nodes, and simultaneously, the terminal device reads the storage module to obtain a second weight value pre-stored by the developer, sets the weight value corresponding to the initial non-authoritative node as the second weight value, and finally, the terminal device inputs the obtained initial authoritative nodes, the first weight numerical values, the initial non-authoritative nodes and the second weight numerical values into a scheme construction module arranged in the terminal device, and the scheme construction module calls a target consensus function preset by a developer to construct the target consensus scheme based on the initial authoritative nodes, the first weight numerical values, the initial non-authoritative nodes and the second weight numerical values.
Therefore, the invention adopts the technical effects that each initial authoritative node and each initial non-authoritative node are determined in each initial node in the initial block chain based on the reputation value, the corresponding first weight value and second weight value are respectively set for each initial authoritative node and each initial non-authoritative node, and finally the target consensus scheme is determined based on each initial authoritative node, the first weight value, each initial non-authoritative node and the second weight value, so that the established target consensus scheme can realize decentralization, and the scheme is safer and can be applied to the public block chain.
Further, a second embodiment of the construction method of the consensus sequence of the present invention is proposed herein, based on the above-described first embodiment of the construction method of the consensus sequence of the present invention.
Referring to fig. 3, fig. 3 is a schematic flow chart of a second embodiment of a construction method of the consensus scheme of the present invention.
Based on the first embodiment of the method for constructing the consensus sequence of the present invention shown in fig. 2, after step S40, the method for constructing the consensus sequence of the present invention may further include:
step B10: constructing a target block chain based on the target consensus scheme, and detecting the target block chain to determine whether transaction data is generated in the target block chain;
in this embodiment, the terminal device inputs the obtained target consensus scheme into a blockchain construction module arranged 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 an excitation 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 target nodes in the target blockchain.
Step B20: if so, calculating the transaction data through all target authoritative nodes in the target block chain together to obtain all target calculation results, wherein the target authoritative nodes are selected by all the nodes of the target block chain based on the target consensus scheme and have transaction verification authority;
in this embodiment, if the terminal device detects that transaction data is generated between target nodes in the target block chain, the terminal device obtains the transaction data, and invokes target authoritative nodes selected by the target nodes in the target block chain based on the common identification scheme to jointly calculate the transaction data and generate 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 block chain, 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, which are included in the target consensus scheme.
Illustratively, for example, the terminal device inputs the obtained target RPOA consensus scheme into a block chain building module arranged in the terminal device, the block chain building module takes the RPOA consensus scheme as a consensus mechanism, and other programmable contracts, programmable assets, excitation mechanisms and other core application components are called to construct the target block chain, and simultaneously, the terminal device detects the transaction behavior of each target node in the target block chain through a built-in data detection module to determine whether each target node generates transaction data, when the terminal device detects that a digital transaction is conducted between a target node X and a target node Y within the target blockchain through the target blockchain, the terminal equipment acquires transaction data generated by the digital transaction, inputs the transaction data into each target authoritative node in the target block chain determined based on the RPOA consensus scheme, obtains a target calculation result by each target authoritative node based on the transaction data, generates a transaction confirmation result corresponding to the target calculation result, and then, the terminal device distributes the transaction confirmation result to each target authoritative node X1, X2, X3,. And XN and each target non-authoritative node Y1, Y2, Y3,. And YN in the target block chain, and simultaneously, the terminal equipment reads a first weight value 3 corresponding to a target authoritative node and a second weight value 1 corresponding to each target non-authoritative node, and determining a first transaction confirmation result corresponding to each target authoritative node and a second transaction confirmation result corresponding to each target non-authoritative node based on a target consensus function carried in the RPOA consensus scheme, and finally determining a final transaction confirmation result based on different weights by the terminal equipment.
It should be noted that, in this embodiment, if the first transaction confirmation result corresponding to each target authoritative node is inconsistent with the second transaction confirmation result corresponding to each target non-authoritative 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 constructing 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;
in this embodiment, after detecting that each target authoritative node in the target block chain calculates to obtain a calculation result, the terminal device inputs each calculation result to the 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 error calculation result is contained in each target calculation result, 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 each calculation result includes 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 block chain generates the transaction data.
For example, after detecting that each target authority node in the target block chain calculates each calculation result, the terminal device inputs each calculation result to the data comparison module, and the data comparison module compares each calculation result with other calculation results in sequence to determine whether the calculation result is consistent, so as to determine whether a target error calculation result exists in each calculation result.
Further, in a possible embodiment, the construction of the consensus scheme of the present invention may specifically further include:
step D10: acquiring a preset node refreshing frequency;
in this embodiment, the terminal device reads the storage module to obtain a node refresh frequency preset by a developer.
Step D20: controlling the target block chain to replace each target authoritative node according to the node refreshing frequency;
in this embodiment, the terminal device sets the target block chain according to the node refresh frequency, so that the target block chain re-randomly selects a new target authoritative node from the candidate nodes according to the node refresh frequency pair.
Illustratively, for example, the terminal device reads the storage module to obtain a node refresh frequency pre-stored by the developer, and determines that the node refresh frequency is 1h, and then, the terminal device sets the target block chain so as to make the target block chain randomly select a plurality of target authoritative nodes in each candidate node every 1h based on the above RPOA consensus scheme.
In this embodiment, a terminal device inputs the obtained target consensus scheme into a blockchain construction module arranged 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 incentive mechanisms, and meanwhile, the terminal device detects the target blockchain through a built-in data detection module to determine whether transaction data is generated between target nodes in the target blockchain, then, if the terminal device detects that transaction data is generated between target nodes in the target blockchain, the terminal device obtains the transaction data, calls each target authoritative node selected by each target node in the target blockchain based on the target consensus scheme to jointly calculate the transaction data and generate a corresponding calculation result, and finally, 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 corresponding transaction result of the target authoritative node based on a first weight value and a corresponding non-authoritative value of the target node included in the target consensus scheme, and determines a corresponding non-authoritative value of the target node.
Therefore, the target block chain is constructed based on the target consensus scheme, the calculation result corresponding to the transaction data is calculated by all the target authoritative nodes in the target block chain when the transaction data is generated in the target block chain, and the transaction confirmation result corresponding to the calculation result is determined by all the target authoritative nodes and all the target non-authoritative nodes in the target block chain, so that the purposes of enabling the transaction confirmation result to be relatively fair and reducing the centralization of the target consensus scheme are achieved.
