Abstract: Blockchain technology creates a new way to store data that solves typical cloud storage problems by running data across multiple devices. Users can get better security for their data, while trust in single breakdowns decreases when they store data through blockchain-distributed ledgers. Data management becomes more trustworthy on blockchain-based cloud storage because its decentralized architecture provides greater privacy protection and data control. Researchers now study ways blockchain works with cloud storage across different applications such as healthcare, IoT devices, and digital forensics. The complete adoption of blockchain-based storage requires us to overcome scalability, communication, and legal difficulties.
