BLOCKCHAIN-NETWORK-BASED JOINT LEARNING METHOD AND JOINT LEARNING DEVICE

摘要

Provided are a blockchain-network-based joint learning method and joint learning device. The method comprises: acquiring an initial model parameter, wherein the initial model parameter is a parameter, used for building an initial model, of a device participating in joint learning; training the initial model parameter, and generating a training result used to update the initial model parameter; and sending the training result to an application server node by means of a state channel, wherein the state channel is an off-chain channel between the device and the application server node, and the off-chain channel is located outside a blockchain network. According to the technical solution provided in the present application, the device participating in joint learning feeds back a training result of the joint learning by means of the state channel, and can meet the requirement for high transactions per second of a combination of the joint learning and blockchain technology.
