How IoT and DePIN Work Together: Building Smart Cities with Decentralized Networks

Smart cities rely on advanced technology to improve urban living, optimize resource usage, and enhance public services. However, most smart city infrastructure is centralized, creating inefficiencies, security risks, and high operational costs. Decentralized Physical Infrastructure Networks (DePIN) and the Internet of Things (IoT) are reshaping this landscape by enabling a decentralized, user-driven model for urban development.

By combining DePIN with IoT, smart cities can leverage decentralized networks for connectivity, data processing, and resource management. This approach reduces costs, increases resilience, and ensures greater transparency. This article explores how DePIN and IoT work together to build smarter, more sustainable cities.
