AI+Crypto is one of the most notable frontier areas in the recent cryptocurrency market. This includes decentralized AI training, GPU DePINs, and censorship-resistant AI models. The main issue with AI training lies in the need for high-speed communication and coordination between GPUs, as neural networks require backpropagation during training. Introducing a decentralized network can significantly slow down the process due to increased network latency and bandwidth. This article also organizes solutions to the current challenges and provides examples of how the integration of cryptocurrency and AI can add significant value.
