A Critical Review of Cloud Computing Architecture Empowered with Blockchain Technology

Blockchain technology (BCT) is a dispersed ledger with data records that are shared among the network’s nodes and contain all the specifics of the transactions that have taken place. Consensus mechanisms are used to confirm every transaction made in the system, and once data has been stored, it cannot be changed. Bitcoin, a well-known digital currency, is supported by blockchain technology, a prerequisite technology. Another term used with blockchain is known as cloud computing. It uses a network of internet-connected servers to gather, organize, and process data instead of a local server or a single machine. This study thoroughly analyses cloud computing architecture based on blockchain, and 12 articles from reputable journals are discovered and evaluated after applying various filters and searching global databases. Data integration, trust, and privacy are the three areas of cloud security examined in this study. The findings demonstrate that blockchain offers a productive platform in this area.
