: Due to its security, blockchain has been dubbed the "next-generation financial technology" for the information era. Through peer authentication, it offers security. among other things, virtual currency, data encryption, and hash value creation. The worldwide financial industry claims that the market for security is huge and that cloud computing, because of its accessibility and efficiency, is now widely used in all IT environments. The concept of blockchain technology, its advancements in research, and blockchain-enabled security in healthcare cloud and electronic vehicles are all covered in this article. cloud The virtual machine agent mechanism handles the dependable data storage, monitoring, and verification responsibilities. In order to construct a blockchain integrity protection mechanism, this is also a prerequisite. The foundation for integrity protection based on blockchain is constructed using the virtual machine proxy model, and the data is owned on time. The unique hash value corresponding to the file created by the Merkel hash tree is used to track changes in the data via the blockchain's smart contract. A blockchain-based cloud data integrity verification system is built using the "block-and-response" mechanism, and the user issues a warning message for data tampering
