Abstract

The invention relates to a federal learning method and device based on a block chain and computer equipment. The method comprises the following steps: establishing a federal learning block chain network through a distributed account book platform, and sending a proposal of uploading a local gradient to an edge terminal through a smart contract, so that the edge terminal generates a transaction about the local gradient according to the local gradient in a state database, and writes the transaction into a new block; receiving an aggregation smart contract calling request sent by an edge terminal, enabling the edge terminal to obtain a local gradient in the new block according to the aggregation smart contract calling request, and carrying out gradient aggregation to obtain an aggregation gradient; and carrying out local model updating and global model updating by adopting a stochastic gradient algorithm. By adopting the method, the security and efficiency of federal learning data can be improved.

Description

technical field [0001] This application relates to the technical field of blockchain, in particular to a blockchain-based federated learning method, device and computer equipment. Background technique [0002] With the rapid development of interconnected devices under the Industrial Internet of Things (IIoT) mode, a large number of infrastructure (storage, computing, communication, etc.) The amount of data generated by the network is increasing rapidly. Through the analysis, mining and sharing of edge network data, it can promote active and effective integration and collaboration among heterogeneous smart devices belonging to different stakeholders, and improve the service quality of emerging edge applications. opened up new possibilities. [0003] In recent years, edge intelligence has conducted a lot of research on network terminal data sharing and fusion by combining AI algorithms and edge computing. For example, deep reinforcement learning is used for resource optimiza...
