Cloud computing is a developing technology used for providing various services such as PaaS, IaaS and SaaS for various applications based on the pay as per usage. The foundation of trust is the assurance and confidence that information, people, entities, data, or processes will deliver the desired outcome with a particular level of assurance. Many times, users even do not have knowledge about processing their personal information over the clouds. In cloud computing, centralized architecture is used for trust modeling, which causes various trust and privacy issues. The trust model is subject to a number of limitations, including single point failure, overload, vulnerability to malicious assaults, particularly harmful recommendations, and lack of accessibility and untraceability of trust proof. There are numerous initiatives underway to increase confidence between cloud users and CSPs. The privacy issues including data leakage and compromising data integrity in the cloud environment. The blockchain technology can provide the solution for the above issues. The Blockchain technology has various advantages as it is decentralized in nature, immutable ledgers, providing full transparency, Instant traceability, data encrypted end-to-end. In the proposed system hybrid consensus algorithms are created to overcome problems of the existing blockchain consensus algorithm. By using blockchain technology creates a Blockchain as a Service (BaaS) in the cloud environment to improve the trust and privacy of users.
