The Development Status of DePIN on Different Public Chains

With the rapid development of the decentralized Internet of Things (DePIN) sector, major public chains are attracting numerous innovative projects. Although Solana is currently in the spotlight, some well-known DePIN projects have started to choose Arbitrum and Polygon as their infrastructure. Meanwhile, public chains focused on DePIN, such as IoTex and Peaq, as well as layer one and layer two public chains actively developing artificial intelligence, like Near and Aptos, are expected to continue their growth momentum.
