With the passing time and evolution of the technological field, the importance of Cloud Computing is exponentially growing for storing, processing, and analyzing the large amount of data generated every second. This paper explores how blockchain technology and zero-knowledge proofs (ZKPs) are being combined with cloud computing to make digital systems more secure and private. It takes a closer look at the fundamental ideas, advantages, and difficulties associated with blockchain, ZKPs, and cloud computing, while also delving into the various scenarios and practical uses for these technologies. In simpler terms, the paper investigates the way these innovative technologies are being used to enhance the security and privacy of data and processes in the digital realm. It doesn’t just focus on what these technologies are but also how they are put into action, making digital systems more robust and less vulnerable to breaches. Essentially, it aims to give readers a comprehensive insight into the most up-to-date methods and solutions for safeguarding cloud computing with the help of blockchain and zero-knowledge proofs.
