Abstract	To overcome the challenges of urbanization and population growth, smart cities use cutting-edge technologies, such as IoT and AI to offer improved public services. Although these advancements have brought convenience, they have raised security and privacy concerns. Blockchain technology has the potential to address these concerns, but existing blockchain frameworks have issues of scalability and efficiency that hinder their ability to meet the smart city demands. In this article, we propose a novel blockchain framework for smart cities, named SC-Chain. Specifically, SC-Chain incorporates a decentralized access mechanism that leverages threshold signatures and BFT-like consensus for efficient node registration and authentication in decentralized systems. Furthermore, we propose a consensus mechanism that utilizes the verifiable random function (VRF) to achieve efficient miner node election, ensuring efficiency, fairness, and security in large-scale smart city systems. We demonstrate the effectiveness and feasibility of the SC-Chain through theoretical analysis and simulations, showcasing its potential to enable the development of secure and efficient smart city infrastructure.
