The Development Overview of DePIN in Various Public Chain Ecosystems

With the continuous development of the DePIN (Decentralized Physical Infrastructure Network) field, major public chain ecosystems are actively laying out related projects. Although Solana has recently received a lot of attention, public chains such as Arbitrum and Polygon have also attracted some well-known DePIN projects. Meanwhile, public chains focusing on DePIN like IoTex and Peaq, as well as public chains emphasizing the development of AI such as Near and Aptos, are also experiencing continuous growth.
