[0022] Embodiments of the present application provide a training method and device of a training architecture based on a blockchain, a computer readable medium, and an electronic device, which are described below with reference to the accompanying drawings.

[0023] Please refer to Figure 1 which shows a flowchart of a training method of a training architecture based on a blockchain provided by some embodiments of the present application, as shown in Figure 1 The training method of the training architecture based on the blockchain provided by the embodiments of the present application can include the following steps: Step S101: generating a training task through a task management contract of a blockchain in the training architecture, the training task including training task parameters, the training task parameters including: a stimulus category and an input sequence.

[0024] In an example, before generating the training task through the task management contract of the blockchain, the training method of the training architecture based on the blockchain provided by the embodiments of the present application can further include the following steps: deploying a task management contract and a data storage contract on the blockchain, wherein the task management contract is used to publish and manage a corresponding training task, and the data storage contract is used to save the training results of the multi-neuron network nodes.

[0025] In an example, before generating the training task through the task management contract of the blockchain, the training method of the training architecture based on the blockchain provided by the embodiments of the present application can further include the following steps: constructing a training architecture of multi-neuron network collaborative training based on a blockchain, the training architecture including: a plurality of biological neuron network nodes, a blockchain capable of generating tokens, and a training coordinator, wherein any one of the plurality of biological neuron network nodes is configured with a corresponding stimulus generator, an electroencephalogram monitoring interface, and a local controller.

[0026] Step S102: executing neural training based on the received training task through the plurality of biological neuron network nodes in the training architecture, to generate node response results of the plurality of biological neuron network nodes.

[0027] In one example, any one of the multiple biological neuron network nodes includes: a local controller, a stimulation controller, a microelectrode array, and a neuron culture unit.

[0028] The training method based on the blockchain training architecture provided in this embodiment of the invention may further include the following steps: The following operations are performed sequentially through the local controller, stimulation controller, microelectrode array, and neuron culture unit: Perform the following operations through the local controller: In response to receiving a training task, the electrical stimulation command control logic is triggered. Receive training data returned by the microelectrode array; The training data, signal features, and training summary are integrated to generate response data; Upload the response data to the blockchain; Perform the following actions via the stimulus controller: Based on the received training task, a preset current stimulation signal and a preset voltage stimulation signal are generated; and voltage pulses and current pulses are output to the microelectrode array. Perform the following operations using a microelectrode array: It receives stimulation signals from the stimulation controller and provides electrical stimulation to nerve tissue; Real-time acquisition of neural network training data, including discharge patterns and reaction timing; Perform the following operations using the neuron culture unit: It receives electrical stimulation from a microelectrode array and performs training based on the electrical stimulation.

[0029] Step S103: The training task parameters and stimulation scheme are dynamically adjusted based on the evaluation results and aggregation results by the training coordinator in the training architecture. The evaluation results are obtained by evaluating the training effect of the node response results of multiple biological neuron network nodes. The aggregation results are obtained by aggregating the node response results of multiple biological neuron network nodes according to the set logic.

[0030] In one example, the training coordinator includes: a data collection module, a response aggregation module, a training evaluation module, a policy generation module, a task publishing module, and a feedback incentive module.

[0031] The training method based on the blockchain training architecture provided in this embodiment of the invention may further include the following steps: The following operations are performed sequentially through the data collection module, response aggregation module, training and evaluation module, policy generation module, task deployment module, and feedback and incentive module: Perform the following operations through the data collection module: Listen to blockchain data storage contract events and read node response data uploaded from multiple biological neural network nodes in the blockchain; Perform the following actions by responding to the aggregation module: The node response data is aggregated and analyzed according to a preset algorithm to obtain the aggregation result; and global training features are extracted based on the aggregation result. Perform the following operations using the training evaluation module: The current training state is evaluated based on the aggregation results, and the evaluation results are obtained. The current training state includes: convergence and performance indicators. Perform the following operations through the policy generation module: Based on the evaluation results, multiple training parameters are dynamically adjusted. These multiple training parameters include at least: stimulation frequency, intensity, and duration. Perform the following operations through the task publishing module: By calling the blockchain task management contract, new training tasks and new training parameters are published; Perform the following operations through the feedback incentive module: The quality of node responses is evaluated based on node response data to obtain evaluation results; and corresponding on-chain incentive tokens are allocated based on the evaluation results.

[0032] In one example, after dynamically adjusting the training task parameters and stimulus scheme based on the evaluation results and aggregation results, the training method of the blockchain-based training architecture provided in this embodiment of the invention may further include the following steps: The response results of multiple biological neuron network nodes are evaluated to obtain target response nodes that meet preset quality requirements; and corresponding on-chain incentive tokens are allocated to the target response nodes.

[0033] In one example, the training method based on the blockchain training architecture provided in this embodiment of the invention may further include the following steps: Initiate training in response to the training strategy; After each round of training, each biological neuron network node submits a corresponding training summary; the training summary includes at least: the current node's unique identifier, the current task's unique identifier, the neural stimulation pattern determined by the type of stimulus sequence in this round, the delay from stimulation to the first neural response, the average firing frequency per unit time, the entropy value of the change in neuronal synaptic weight distribution, the timestamp, the hash calculated from the potential waveform or encoded sequence, and the signature generated in the trusted execution environment. The training coordinator, based on the training summary, sequentially performs the following steps: filtering valid data; filtering each biological neuron network node to obtain activated nodes; and generating the training strategy for the next round. Filter valid data by performing the following steps: Signature verification is performed by verifying the match between the signature and the node's identity. Check whether the current task is within its validity period based on the time window; Verify that the task matches the task identifier; The next training strategy is generated by performing the following operations in sequence: The stimulation parameters are optimized, the incentive nodes are selected, and the training strategy for the next round is encoded and published by calling the task management contract; Specifically, the stimulation parameters are optimized by performing the following operations: based on the high-scoring nodes of the previous round, effective stimulation types and stimulation parameters are extracted to obtain effective stimulation types and stimulation parameters, so as to generate the stimulation sequence for the next round based on the stimulation parameters.

[0034] In a specific application scenario, the submitted training summary is as follows:

[0035] In practical applications, the evaluation scoring model can use the following formula: Formula (1); In the above formula (1), , indicating whether learning has occurred; response_latency_ms is the delay from stimulus to the first neural response, used to judge reaction speed and stimulus effectiveness; mean_spike_rate is the average firing rate per unit time, used to measure the activity level of neurons; coefficients α, β, and γ can be set according to task objectives (such as enhancing reaction speed, synaptic adjustment, etc.).

[0036] In a specific application scenario, after evaluating all nodes, the coordinator generates the next round of training strategy, including: Step a1: Optimize the stimulation parameters.

[0037] Based on the high-scoring nodes from the previous round, extract their most effective stimulus types and parameters, and use them to generate the stimulus sequence for the next round. If a stimulus leads to generally low potential and high surge, increase its probability of occurrence; if a stimulus causes a significant increase in synaptic entropy, it indicates that learning has occurred and is preferentially retained.

[0038] Step a2: Select the excitation node.

[0039] Select only a subset of nodes to participate in the incentive: Select the Top K nodes based on their scores. K can be set according to the needs of different application scenarios, and no specific restrictions are imposed here.

[0040] Step a3: Coding and releasing the new strategy.

[0041] The new strategy is coded and published by calling the task management contract.

[0042] like Figure 2 As shown, the training system based on the blockchain training architecture includes the following modules: Multiple biological neuron network nodes (BNN modules), each equipped with a stimulus generator, an EEG monitoring interface, and a local controller.

[0043] like Figure 3 The diagram shown is a schematic of the structure of a BNN node.

[0044] Each BNN node is essentially a composite system of experimentation and computation, and the node composition is as follows: Figure 3 As shown, it can be divided into four main modules: Local Controller: The local controller is typically an embedded device or a lightweight server used for blockchain interaction and control of experimental processes. It receives tasks by periodically polling or subscribing to blockchain events, triggering the electrical stimulation command control logic upon receiving a task. Simultaneously, it receives training data returned by the microelectrode array, analyzes signal characteristics, generates summaries, integrates this data into response data, and uploads all response data to the blockchain.

[0045] Stimulation controller: Essentially a circuit control module used to receive task instructions, generate preset current and voltage stimulation signals, and output voltage and current pulses to the microelectrode array.

[0046] Microelectrode arrays: Essentially, they are electrode arrays (miniature sensors) that serve as the physical interface for contacting nerve cells, closely attached to nerve tissue. They have two main functions: first, to receive stimulation signals from the stimulation controller and electrically stimulate the nerve tissue; and second, to collect training data such as the firing patterns and reaction timing of the neural network in real time.

[0047] Neuron culture unit: contains living neurons (such as rat neural stem cells) that receive electrical stimulation from a microelectrode array for training.

[0048] The training method based on the blockchain training architecture provided in this embodiment of the invention can effectively guarantee the data credibility of BNN nodes.

[0049] In practical applications, each BNN node autonomously generates, collects, and calculates training results before uploading them to the blockchain, which carries the risk of data falsification. The blockchain-based training architecture training method provided in this invention employs a trusted execution environment. The data transmission and computation of both the local controller and the stimulus controller are executed within this environment, ensuring the authenticity of stimuli and responses, thereby significantly improving training accuracy.

[0050] A trusted execution environment was chosen because the electrophysiological data output by biological neural networks (such as synaptic entropy, sequential firing, and noise distribution) is high-dimensional, floating-point, and unsuitable for direct conversion into ZKP (Zero Knowledge Proof) circuits. The ZKP generation process places excessive demands on the local controller computing power of BNN nodes, which is not conducive to deployment in biological experimental equipment.

[0051] The task management contract and data storage contract are deployed on the blockchain. The task management contract is used to publish and manage the corresponding training tasks, and the data storage contract is used to store the training results of the multi-neuron network nodes.

[0052] In practical applications, task management contracts are run for task scheduling, response summary recording, node performance evaluation, and reward distribution.

[0053] Train the coordinator to analyze task execution results and generate aggregation strategies.

[0054] The training coordinator is responsible for receiving neural response return data uploaded from multiple BNN nodes, performing training effect evaluation and response aggregation, and then dynamically adjusting training task parameters and stimulus schemes. All training transmission data is recorded within this module. The training coordinator includes the following modules: Data collection module: Monitors blockchain data storage contract events and reads response data uploaded by multiple BNN nodes from the blockchain. Response aggregation module: Performs aggregation analysis on node responses according to a preset algorithm to extract global training features.

[0055] Training evaluation module: Evaluates the current training status based on the aggregated results, such as convergence and performance metrics.

[0056] Strategy generation module: Dynamically adjusts training parameters such as stimulus frequency, intensity, and duration based on evaluation results.

[0057] Task publishing module: Calls the blockchain task management smart contract to publish new training tasks and parameters.

[0058] Feedback Incentive Module: This module allocates on-chain incentive tokens based on the quality of node responses, encouraging active participation. In practical application scenarios, the following methods are adopted: Figure 2 The training process of the training system shown is as follows: Step b1: The task management contract on the blockchain generates training task parameters (including stimulus types, input sequences, etc.). Step b2: After receiving the task, each biological neuron network node performs neural training and collects response data. Then, it extracts electrical activity indicators (such as response delay, average firing rate, synaptic change entropy, etc.), generates a training summary, and uploads it to the blockchain. Step b3: The training coordinator aggregates the response results of multiple BNN nodes according to the set logic and generates the guidance strategy for the next round of training; Step b4: The blockchain allocates on-chain token incentives to nodes with high-quality responses based on response quality assessment.

[0059] In practical applications, the incentive mechanism involves issuing tokens to nodes based on participation, response speed, and learning improvement.

[0060] It should be noted that blockchain, as a distributed ledger technology, has the characteristics of decentralization, immutability, and verifiability, making it naturally suitable as a coordination and recording platform among multiple heterogeneous nodes.

[0061] The training method provided in this invention not only performs neural training based on received training tasks to generate node response results for multiple biological neuron network nodes, but also dynamically adjusts training task parameters and stimulation schemes based on evaluation and aggregation results. Furthermore, the training method utilizes blockchain to achieve trusted task scheduling and response recording in multi-BNN collaborative training. Additionally, the training method effectively avoids privacy leaks and performance bias issues caused by centralized scheduling centers. Moreover, the training method supports neural networks trained under different physical conditions to participate in training together, enhancing the robustness of the training architecture. Furthermore, the training method does not require trust in the node operators; even if BNN nodes are run by different laboratories, as long as their trusted execution environment is trustworthy, their participation results can be accepted by the training architecture. Furthermore, the training method constructs on-chain trajectories for neural response data, which can be used for monitoring, interpretability research, and retraining traceability. Finally, the training method has good scalability and can be extended to biological distributed inference networks in the future.

[0062] In the above embodiments, a training method based on a blockchain-based training architecture is provided.
