In an example, the initial values of the preset threshold vector are set based on the statistical analysis of historical carbon data, the initial value of the time series smoothness score threshold can be , the initial value of the logical consistency score threshold can be , and the initial value of the industry deviation score threshold can be , and the initial values are further dynamically adjusted by an online learning mechanism combined with verification feedback. Since the time series smoothness score is greater than the time series smoothness score threshold , the logical consistency score is greater than the logical consistency score threshold , and the industry deviation score is greater than the industry deviation score threshold , the verification instruction is obtained as follows: execute regular sampling, the priority is P3, and the verification data range is random sampling of no more than of the enterprise original carbon data and traceable data.

The neighbor node set is a node group obtained through neighborhood sampling, which is composed of first-order and second-order neighbor nodes of the target enterprise node. The graph convolution neural network is a deep learning model for feature extraction based on graph structure data, and is used to aggregate feature information of the target node and its neighbor nodes. On the basis of the initial feature vector output in the feature engineering layer, the graph convolution network aggregation layer adopts a two-layer graph convolution structure to realize feature extraction. The input dimension of the first-layer graph convolution structure is consistent with the dimension of the initial feature vector, and the output dimension is 128. The output dimension of the second-layer graph convolution structure is 64, and the activation function is ReLU. Finally, a 64-dimensional graph embedding vector is obtained. When the graph convolution neural network is trained, the learning rate is set to 0.001, the iteration is 200 cycles, the Adam optimizer is used, the contrast loss function is adopted, and the Dropout rate of 0.3 and L2 regularization are used to enhance the generalization ability. In the embodiment, the number of neurons, learning rate and training parameters of the graph convolution network are all examples, and a person skilled in the art can set them according to the actual situation, and the embodiment does not limit them.

[0093] Specifically, first, an initial feature vector is obtained and the enterprise identifier corresponding thereto In the industrial knowledge graph corresponding target enterprise node is obtained through an identity matching algorithm ; then, taking the target enterprise node as a starting point, first-order neighbor nodes directly connected to the target enterprise node and second-order neighbor nodes indirectly connected to the target enterprise node are obtained through a random walk sampling algorithm to obtain a neighbor node set ; finally, based on the neighbor node set and the initial feature vector , feature propagation and aggregation operations are performed through a graph convolutional neural network, inter-layer feature transmission is performed using a graph convolution formula, and after two layers of graph convolution calculation, a graph embedding vector is obtained.

The fused feature vector is a comprehensive feature representation obtained by concatenating the initial feature vector and the graph embedding vector. The fully connected neural network contains three hidden layers with 256, 128, and 64 neurons respectively, all using ReLU activation functions. The output layer has three neurons corresponding to the three confidence scores. During training, the learning rate is set to 0.0005, with 150 iterations, using the AdamW optimizer and mean squared error as the loss function. He initialization and a step-decay learning rate strategy are employed to stabilize the training process. The fully connected neural network is a deep learning model where each layer of neurons is connected to the next fully connected layer for nonlinear transformation of features. The base confidence score is the original confidence score calculated by the neural network. The normalized exponential function is a mathematical function that converts a vector into a probability distribution, used for normalizing the confidence score. In this embodiment, the number of neurons, learning rate, and training parameters of the fully connected neural network are examples; those skilled in the art can set them according to actual conditions, and this embodiment does not impose any limitations.

[0100] Specifically, firstly, based on the initial feature vector And graph embedding vector By concatenating the feature dimensions through vector concatenation, a fused feature vector is obtained. Then based on the fused feature vector The basic confidence score is obtained by calculating using a three-layer fully connected neural network and performing a nonlinear transformation using the ReLU activation function. Ultimately based on the baseline confidence score The multidimensional confidence vector is obtained by calculating the normalized exponential function and the softmax function. Each dimension represents a confidence score for a different aspect, including the time series smoothness score. Logical consistency score Deviation score from peers .

[0101] This embodiment, based on initial feature vectors and graph embedding vectors, achieves credibility assessment of carbon data in both its own characteristics and industry-related characteristics through cascaded processing of vector concatenation, fully connected neural networks, and normalized exponential functions. This solves the problem that traditional single-dimensional assessment cannot fully reflect data credibility, improves the comprehensiveness and accuracy of confidence assessment, and provides a quantitative basis for generating verification instructions for the comprehensive decision-making level.

[0102] Furthermore, this embodiment provides a step for obtaining a list of verification groups based on verification instructions and raw carbon data using a quantum consensus model, including:

[0104] obtaining the task attribute through task analysis based on the verification instruction and the original carbon data;

[0105] obtaining the verification group list through the quantum consensus model based on the verification node state and the task attribute.

[0106] The node management service is a system service for maintaining and managing the real-time state of all registered verification nodes, and the verification node state is obtained by calling the node registration table and state monitoring interface; the verification node is a server or container deployed with a trusted execution environment technology, used to independently execute verification algorithms in a protected isolated environment; the verification node state is a dynamic state set of all available verification nodes, including node identification, professional ability label, and current resource utilization; task analysis is a process of obtaining key features of verification tasks according to the verification data range in the verification instruction and the enterprise attribute information in the original carbon data, used to determine the required verification algorithm type and resource constraint condition, and the verification task is obtained according to the verification instruction; the task attribute is a structured data object that completely describes the technical features of each verification task, including target enterprise industry, verification algorithm type, urgency level, and resource demand; the quantum consensus model is a random assignment algorithm based on the principle of quantum walk, used to generate an unpredictable and task demand matching verification group allocation scheme.

[0107] Specifically, first, the target enterprise identification is determined based on the verification data range in the verification instruction, the industry classification code and data feature mode of the target enterprise are obtained based on the corresponding enterprise basic information in the original carbon data, and the urgency level in the verification instruction is obtained; then, based on the complete verification instruction, the node management service is called to query the attribute information of all active verification nodes through the node registration table interface, and the current resource utilization and response performance indicators of each verification node are collected in real time through the state monitoring interface, and the verification node state including node identification, professional ability label, and current resource utilization is obtained; then, based on the industry classification code of the target enterprise, the data feature mode, and the urgency level in the verification instruction, the required verification algorithm type and resource demand of the verification task are calculated through the task analyzer to obtain the complete task attribute; finally, based on the verification node state and the task attribute, the quantum consensus model is executed to perform a multi-dimensional optimization node matching and anti-prediction random selection process, and a verification group list that meets the professional requirements of the verification task, load balancing, and unpredictability is obtained.

[0108] For example, the embodiment assumes that the received verification instruction is to perform logical contradiction checking, the priority is P2, the data range to be verified is specifically designated as the current full amount of raw carbon data of enterprise B, and the urgency is P2; based on the registration information of enterprise B in the raw carbon data, it is determined that the industry classification thereof is industry D, and the data characteristic mode is high-frequency sampling; the verification node identifier obtained through the node management service is N201, N202, and N203, and the corresponding verification node state is: {N201: ["perform logical contradiction checking", "high-frequency data processing"], resource utilization rate }、{N202: ["abnormality detection"], resource utilization rate }、{N203: ["perform logical contradiction checking", "traceability analysis"], resource utilization rate };the task attribute obtained through task analysis is {industry: "industry D", verification algorithm type: ["perform logical contradiction checking"], urgency: P2, resource requirement: };based on the verification node state and the task attribute, the verification group list is obtained through quantum consensus model optimization calculation as [N201, N203].

[0109] The embodiment realizes unified monitoring and scheduling of verification node resources through the node management service, converts abstract verification instructions into calculable task feature vectors through task analysis, realizes anti-conspiracy random assignment and multi-objective optimization selection through the quantum consensus model, ensures system data consistency through complete parameter transmission and state maintenance, realizes professional matching of the verification group, resource balance, and unpredictability of the selection process, eliminates the possibility of collusion and human manipulation risk in the verification link from the mechanism, and significantly improves the fairness, security, and resource utilization efficiency of the carbon data verification system.

[0110] Further, the embodiment provides a step of obtaining a verification group list based on verification node states and task attributes through a quantum consensus model, comprising:

[0111] obtaining an initial quantum graph based on the verification node state through a quantum state initialization algorithm;

[0112] obtaining quantum potential configuration through potential optimization based on the task attribute;

[0113] obtaining the verification group list through the quantum consensus model based on the initial quantum graph structure and the quantum potential configuration.

[0114] The quantum state initialization algorithm is a calculation method for mapping the verification node state to a graph structure with a quantum superposition state distribution, and is used to construct an initial quantum graph capable of quantum walk evolution; the initial quantum graph is a graph model taking the verification nodes as vertices, taking the professional similarity between the verification nodes as edges, and giving each verification node an initial quantum state probability amplitude distribution; the potential energy optimization is a calculation process of dynamically adjusting the potential energy value on each edge in the initial quantum graph according to the task attributes, and is used to construct a quantum potential energy landscape adapted to the task to guide the quantum walk path; the quantum potential energy configuration is a set of potential energy values on all edges in the initial quantum graph, and the values are determined by the professional similarity of the verification node and the corresponding verification task, and the resource utilization rate of the verification node.

[0115] Specifically, as shown in the figure, Figure 3 first, based on the professional ability labels of all verification nodes in the verification node state, the professional similarity between any two verification nodes is calculated through the quantum state initialization algorithm, and the edge connection is established according to all professional similarities and a preset professional similarity threshold, that is, the edge connection is established only when the professional similarity is greater than the preset professional similarity threshold, each verification node is mapped to a quantum node in the quantum graph, and the initial quantum state is assigned to each verification node using the uniform superposition principle , obtaining an initial quantum graph with nodes and edges; then, based on the verification algorithm type requirement in the task attribute and the professional ability label in the verification node state, the professional matching degree score of each verification node and the verification task is calculated through the potential energy optimization algorithm, and the current resource utilization rate and network topology information of the verification node are combined to calculate the potential energy value on each edge , wherein are the indexes of the two different verification nodes connected by the edge, respectively, the lower the professional matching degree or the higher the node load, the greater the potential energy value on the corresponding edge, and the complete quantum potential energy configuration is obtained ; finally, based on the initial quantum graph structure and the quantum potential energy configuration, the quantum consensus model is used to project and measure the system quantum state by using continuous-time quantum walk evolution, and the final selected verification node combination is determined by using a weighted random selection algorithm according to the probability distribution obtained by measurement, obtaining a verification group list In the quantum consensus model of the embodiment, each verification node is mapped to a quantum bit, the ground state represents that the verification node is not selected, and the excited state represents that the verification node is selected, and the total state of the system is the tensor product of all verification node quantum bits; the quantum circuit includes an initialization phase, an evolution phase and a measurement phase, and in the initialization phase, all quantum bits are in a uniform superposition state , This indicates an initial equal probability selection. This represents the total number of verification nodes. This serves as the index number of the verification node in the initial quantum graph; the evolution phase employs a continuous-time quantum walk model, with evolution operators... Hamiltonian From the initial quantum diagram The adjacency matrix A and the quantum potential energy-based configuration Constructed diagonal potential matrix Build together For evolution time, The starting node number is used to define the edges in the potential energy matrix. Individual potential energy values ​​in the matrix are dynamically configured based on task attributes and the status of verification nodes. The measurement phase occurs during the evolution time. Then, the quantum state is projected and measured, and the list of verification groups is obtained by weighted random sampling algorithm based on the probability distribution.

[0116] This embodiment, based on complete verification node states and task attributes, first constructs a quantum graph structure that accurately reflects the capability relationships of verification nodes through quantum state initialization. Then, it achieves precise matching between task requirements and node capabilities through potential energy optimization. On this basis, it realizes node selection with both randomness and optimization characteristics through quantum walk evolution and subsequent quantum state measurement. The evolution process of quantum walks relies on fundamental properties such as quantum superposition and interference. Its inherent randomness stems from the no-cloning principle and measurement collapse behavior of quantum systems, belonging to true randomness at the physical level. This randomness is fundamentally different from traditional cryptographic pseudo-random numbers generated by deterministic algorithms and are essentially predictable. Thus, at the mechanism level, it significantly improves the anti-collusion capability, professional matching degree, and overall intelligence level of the verification group assignment process.

[0117] Furthermore, this embodiment provides a step for obtaining on-chain evidence records based on a verification group list using national cryptographic algorithms and a blockchain evidence storage contract, including:

[0118] Based on the verification group list, raw carbon data and preset business rules, the group signature is obtained through the national cryptographic SM2 threshold signature algorithm and the national cryptographic SM3 hash algorithm;

[0120] The SM2 threshold signature algorithm is a threshold signature scheme based on elliptic curve cryptography approved by the National Cryptographic Administration, which is used to share signature power among multiple verification nodes in the verification group list. The distributed key generation and signature collaboration process ensures that only when a preset threshold number of verification nodes agree can a valid signature be generated. The SM3 hash algorithm is a cryptographic hash algorithm approved by the National Cryptographic Administration, which is used to hash the original carbon data and the preset business rules to generate a fixed-length data digest. The one-way hash function ensures data integrity and tamper resistance. The group signature is a digital signature obtained by multiple verification nodes in the verification group list based on the SM2 threshold signature algorithm and the SM3 hash algorithm, which represents the consensus approval of the verification result.

[0121] Specifically, first, based on the identity of each verification node in the verification group list, the public key certificate and private key shard of the corresponding verification node are obtained through the node management service. Meanwhile, based on the original carbon data and the preset business rules, the data hash value is calculated through the SM3 hash algorithm . Then, based on the data hash value and the private key shard of each verification node, the distributed signature protocol is executed through the SM2 threshold signature algorithm, including key agreement, partial signature generation, and signature aggregation steps, to obtain the complete group signature . Subsequently, based on the group signature , the data hash value , and the verification metadata, the storage transaction is obtained through the input interface of the blockchain storage contract, and the verification metadata includes the verification task identifier and the verification node list. Finally, the storage transaction is submitted to the blockchain network by calling the storage method of the blockchain storage contract, and the tamper-proof on-chain storage record is obtained after consensus verification .

[0122] For example, this embodiment assumes that the verification group list , the original carbon data is , the preset business rules are , the data hash value is calculated through the SM3 hash algorithm , the distributed signature is executed through the SM2 threshold signature algorithm based on the nodes in the verification group list, and the group signature is finally aggregated . Subsequently, the storage transaction is uploaded to the blockchain through the blockchain storage contract, and the on-chain storage record is generated .

[0123] The embodiment realizes reliable guarantee of data integrity through the national secret SM3 hash algorithm, realizes anti-repudiation and anti-single point failure of multi-core verification node cooperative signature through the national secret SM2 threshold signature algorithm, realizes automation and transparency of the storage process through the block chain storage contract, realizes high security storage and non-tamperable traceability of the carbon data verification result through a complete technical closed loop, and improves the anti-fake ability, audit credibility and system robustness of the carbon data storage system.

[0126] The confidence decision module: based on the business logic feature sets and the data variation degrees, verification instructions are obtained through a pattern recognition confidence model, the pattern recognition confidence model comprising a feature engineering layer, a graph convolution network aggregation layer, a multi-dimensional confidence generation layer and a comprehensive decision layer;

[0127] The quantum consensus module: based on the verification instructions and the original carbon data, a verification group list is obtained through a quantum consensus model;

[0128] The national secret storage module: based on the verification group list, on-chain storage records are obtained through the national secret algorithm and the block chain storage contract.

[0129] The data tracing module, confidence decision module, quantum consensus module, and national cryptographic evidence storage module are all located on the server. The server receives data transmitted from the acquisition devices and performs further analysis. The acquisition devices include enterprise energy metering terminals, production process data collectors, data interfaces of third-party monitoring equipment, and blockchain light node gateways. The data tracing module is used to realize the whole-process trusted processing of carbon data from acquisition to feature extraction. It obtains a feature set reflecting data quality and business logic through carbon stream tracing filtering and business rule execution. The confidence decision module performs multi-dimensional credibility assessment based on the business logic feature set and data variability, through pattern recognition. The confidence model generates differentiated verification instructions; the quantum consensus module dynamically constructs anti-collusion verification groups based on the verification instructions and raw carbon data, and achieves random, fair, and professionally matched assignment of verification nodes through the quantum consensus model; the national cryptographic evidence storage module is used to cryptographically securely store the verification results of the verification groups, and achieves tamper-proof storage of verification evidence through national cryptographic algorithms and blockchain evidence storage contracts. When the blockchain evidence storage contract detects data anomalies or inconsistent verification results, the carbon data evidence storage system automatically triggers a re-verification process, sends a re-evaluation instruction to the confidence decision module, and updates the verification group list, forming a closed-loop control. The modules collaborate through standardized data interfaces and event-driven mechanisms. The output of the data traceability module serves as the input of the confidence decision module. The verification instructions generated by the confidence decision module trigger the node assignment process of the quantum consensus module. The verification group list output by the quantum consensus module is handed over to the national cryptographic evidence storage module for final evidence storage. This forms a complete closed loop from trusted data processing, intelligent decision-making, consensus assignment to secure evidence storage, and together constructs a carbon data evidence storage system with high reliability, anti-collusion, and traceability.
