On the basis of the foregoing embodiment, the artificial intelligence training method based on the blockchain provided in this embodiment specifically includes the following steps:
As shown in fig. 1, an AI training task initiating node may broadcast an AI training task in a blockchain network, where the AI training task is used to request an AI training node in the blockchain network to train a model, so as to obtain model parameters of the model. The AI training task may specifically correspond to an intelligent contract white paper, and specifically, the AI training task initiating node may broadcast the intelligent contract white paper corresponding to the AI training task in the blockchain network. In a specific implementation manner, the AI training task initiating node may sign the intelligent contract white paper by using its own private key, and broadcast the intelligent contract white paper signed by the private key to the blockchain network.
Specifically, the intelligent contract white paper may include a training result detection sample or a link and a training result reward scheme corresponding to the training result detection sample. The training result detection sample is specifically used for verifying a training result, and the training result may be specifically a trained model parameter. The embodiment does not limit the specific form and content of the training result rewarding scheme. For example, the training outcome reward scheme may include at least one of: completing model training within a preset time after an AI training task initiating node issues the AI training task to obtain reward money of the first N AI training nodes of the model parameters; the accuracy of the model parameters obtained after model training is completed is greater than or equal to 95% of the reward amount of the AI training nodes; the correct rate of the model parameters obtained after model training is completed is greater than or equal to 90% of the reward amount of the AI training nodes; the billing rewards available to the first billing node that meets the minimum criteria. In particular, the reward amount or billing reward may be Token. In addition, the AI training task initiating node or the accounting node can lock the reward amount or the accounting reward related to the training result reward scheme.
Specifically, after the AI training task initiating node broadcasts the intelligent contract white paper corresponding to the AI training task in the blockchain network, the AI training node and the billing node may receive the intelligent contract white paper corresponding to the AI training task from the blockchain network.
After the AI training node receives the intelligent contract white paper corresponding to the AI training task from the blockchain network, the AI training node may start a computing resource corresponding to the AI training node, where the computing resource may specifically be a Graphics Processing Unit (GPU) computing cluster. Specifically, the AI training node may perform model training according to the GPU computing cluster, and obtain trained model parameters. Further, the AI training node may also broadcast the model parameters into the blockchain network so that accounting nodes in the blockchain network may receive the model parameters.

When the accounting node receives the model parameters broadcast by an AI training node in the blockchain network, the accounting node can verify the accuracy of the model parameters according to training result detection samples included in the intelligent contract white paper. When the accuracy of the model parameter satisfies the training result reward scheme, the AI training node may obtain the corresponding reward amount, that is, the accounting node may record the reward amount that the AI training node can obtain in the blockchain account book.

And 304, if the model parameters pass the verification, the accounting node determines reward information obtained by the AI training node according to the training result reward scheme.
And 305, writing the reward information into a block chain account book by the accounting node.
For example, when the accuracy of the model parameters satisfies the training result reward scheme as described above, the AI training node may obtain the corresponding reward amount, i.e., the accounting node may record the reward amount that the AI training node can obtain in the blockchain account book.
Wherein the AI training node, the AI training task initiating node, and the accounting node are participating nodes in the blockchain network.

In particular, a plurality of accounting nodes, e.g., accounting node a and accounting node B, may be included in the blockchain network. After the accounting node a verifies the model parameters broadcast by an AI training node, the corresponding verification result may also be sent to other accounting nodes, for example, accounting node B. Accounting node B may verify the verification result of accounting node a. If accounting node B determines that the validation of accounting node A is incorrect, accounting node B may regenerate the reward record based on the rate of correctness of the model parameters validated by accounting node B. If the accounting node B determines that the result of the verification by the accounting node a is correct, the accounting node B may perform the generation of the next block on this basis.
Optionally, the AI training task initiating node may not lock its Token. The Token for rewarding AI training nodes and billing nodes in the blockchain network may be blockchain self-generated. That is, the blockchain may be a commonweal blockchain. Specifically, the model parameters obtained by training the AI training node may be shared with the participating nodes in the blockchain network.
