The advent of blockchain technology has brought about an enormous shift in financial transactions, while the extensive integration of cloud computing in IT systems has experienced substantial growth due to its efficiency and availability. Cloud computing continues to face challenges, although there have been efforts made to address issues around privacy and security. This paper examines the potential of blockchains, renowned for their decentralized nature and consensus-based software architecture, to provide effective solutions for distributed applications, and hence address issues commonly associated with centralized systems. The study examines the legal and technical dimensions to investigate how blockchains can effectively tackle the issues of cloud computing. In addition to proposing solutions to improve security and privacy, the current use of blockchain technology in cloud storage applications is examined by comparing all security techniques with simulated blockchain. By leveraging the decentralized attributes of blockchain technology, we aim to overcome the limitations of centralized cloud systems. It investigates the potential of this technology to effectively circumvent the constraints of traditional cloud computing platforms.
