Data generation and consumption have significantly increased recently, necessitating the need for secure and dependable file storagesolutions. The vulnerability of current centralized storage solutions to data breaches and hackers compromises the security andintegrity of user data. These problems may have a workable solution in a decentralized file storage system. In order to offer a secureand dependable storage solution, this paper proposes a blockchain-based file storage (BBFS) system that takes advantage of featureslike immutability, transparency, and security. Any user can upload unlimited files (one at a time) with this proposed system. Users candownload and access those files on their machines as well as all other peers. As soon as a peer uploads a file, it is placed in a blockalong with the user name, file size, and file information. It is not possible to change or remove these blocks because they are addedto the current blockchain. These blocks can be connected with cloud storage, giving users a safe place to store and access their filesthat cannot be altered. By integrating this proposed system with cloud storage, customers can take advantage of the scalability andsecurity of cloud services as well as the immutability and security of blockchain. The proposed system addresses the cost and scalability roblems that make to be widely applicable.
