Abstract

With the exponential growth of cloud storage and smart grid systems, ensuring secure access and timely fault detection has become paramount. This manuscript explores two distinct yet interconnected technological domains: blockchain-based access control for cloud data storage and the application of the Internet of Things (IoT) in smart grid fault detection and isolation. Before 2021, innovations in blockchain laid the groundwork for decentralized and tamper-proof access frameworks that strengthened data privacy and user authentication in cloud environments. Simultaneously, IoT systems were employed in power distribution networks to enhance real-time monitoring, predictive fault detection, and self-healing capabilities. This study examines the core contributions and limitations in both areas, draws comparisons across notable frameworks and solutions, and statistically evaluates the extent of their real-world applications. Through a methodological review and results derived from secondary data analysis, the manuscript aims to consolidate the academic and industrial contributions prior to 2021. The dual focus highlights the potential synergy between secure data access mechanisms and intelligent grid infrastructure, offering insights for future integration across emerging cyber-physical systems.
