Traditional centralized storage systems face limitations like single points of failure, security breaches, and limited scalability. Decentralized file storage systems using blockchain offer a compelling alternative. This paper presents such a system, focusing on data integrity, privacy, and accessibility without a central authority. Blockchain's distributed ledger secures data transactions, ensuring transparency and immutability. Cryptographic hashing, data encryption, and consensus algorithms enhance security and prevent unauthorized access. Files are sharded and distributed across a node network, with blockchain storing metadata for retrieval. This architecture improves fault tolerance and enables cost-effective scaling by leveraging unused storage. Token-based incentives encourage node participation. Potential applications include secure data sharing, archival storage, and sensitive information management in sectors like healthcare, finance, and IoT. This blockchain-based storage system offers a secure, scalable, and transparent platform, addressing the vulnerabilities of traditional systems.
