As organizations increasingly adopt cloud computing to manage and store critical data, concerns surrounding the security, privacy, and integrity of cloud-based systems have grown in parallel. Traditional cloud infrastructures, while offering flexibility, scalability, and cost-efficiency, often rely on centralized control mechanisms that can become single points of failure and targets for cyberattacks. Issues such as unauthorized data access, insufficient transparency, and the inability to verify data authenticity have prompted researchers and practitioners to explore innovative security-enhancing technologies. This paper investigates the integration of blockchain technology into cloud computing as a strategic approach to addressing these concerns and enhancing the overall security posture of cloud environments. Blockchain, a decentralized and tamper-resistant digital ledger, offers several inherent characteristics such as decentralization, immutability, and transparency that align well with the security needs of modern cloud systems. The study explores how these blockchain features can be harnessed to improve key cloud security parameters, including data privacy, integrity, access control, and auditability.
It examines existing blockchain-based security models and frameworks deployed in various cloud contexts, assessing their architecture, functionality, and practical effectiveness. Particular attention is given to the use of smart contracts for automated access control, decentralized identity management for user authentication, and immutable audit trails for compliance and accountability. Through a critical evaluation of the literature and real-world implementations, the paper identifies both the advantages and the limitations of blockchain integration. While blockchain significantly enhances trust, accountability, and resilience in cloud operations, it also introduces challenges such as scalability issues, integration complexity, and regulatory uncertainty. To address these, the paper offers recommendations for organizations considering blockchain adoption and highlights the importance of tailored, hybrid architectures that combine the strengths of both technologies. In conclusion, this study provides a comprehensive analysis of how blockchain can serve as a viable and impactful solution to cloud security challenges. It underscores the need for continued research and cross-disciplinary collaboration to refine blockchain-cloud integration strategies and unlock new opportunities for secure, decentralized, and efficient digital ecosystems
