DePIN, which stands for Decentralized Physical Infrastructure Network, refers to a network system that connects and manages physical hardware devices in a decentralized manner. The successful cases of Filecoin and Helium demonstrate that combining blockchain technology with real-world physical infrastructure can create disruptive solutions. These projects have not only innovated technically but also successfully applied cryptoeconomics to solve real-world problems, showcasing the feasibility and potential of the DePIN model. By reviewing the successful DePIN projects in history and summarizing their successful experiences, we can focus on the new development directions and potential brought by the combination of AI and DePIN amidst the AI wave.
