Amidst the exponential growth in data volumes and growing apprehensions regarding centralized control, decentralized cloud storage systems have emerged as a beacon of promise. This study presents a comprehensive examination of these systems, delving into their structural intricacies, benefits, and hurdles. The essence of decentralized cloud storage lies in dispersing data across a network of nodes, obviating the necessity for a central governing entity. Through the utilization of blockchain technology and cryptographic methods, information is encrypted, fragmented, and dispersed among myriad nodes, ensuring both redundancy and heightened security. This framework effectively mitigates the inherent risks of data loss or tampering associated with centralized infrastructures, thus bolstering data integrity and confidentiality. In summary, decentralized cloud storage systems signify a revolutionary shift in data management paradigms, furnishing a resilient, scalable, and secure alternative to centralized storage models. Ongoing research and development endeavours are imperative to surmount extant challenges and fully harness the transformative potential of this groundbreaking technology.
