Decentralized physical infrastructure network (DePIN) is an emerging research area in Web3 and IoT domains, which leverage blockchain, IoT and tokenomics to incentivize communities to build physical infrastructure networks and machine economy from the ground up. DePINs are expected to disrupt existing IoT business models and enable developers to build machine-driven and decentralized IoT applications. A lot of research challenges need to be addressed to fully realize the ultimate vision of DePIN - giving back control of devices and data to users.
