The increasing reliance on traditional centralized storage systems has highlighted significant limitations, such as single points of failure, data breaches, and restricted scalability. To address these challenges, decentralized file storage systems leveraging blockchain technology have emerged as a robust alternative. This paper explores the design and implementation of a decentralized storage solution that ensures data integrity, privacy, and accessibility while eliminating the need for a central authority.Blockchain technology provides a distributed ledger to secure and authenticate data transactions, ensuring transparency and immutability. By employing mechanisms such as cryptographic hashing, data encryption, and consensus algorithms, the proposed system offers enhanced security and prevents unauthorized access. Data files are fragmented into smaller pieces using a sharding technique and distributed across a network of nodes, with blockchain storing metadata and pointers for efficient retrieval.This decentralized architecture not only enhances fault tolerance but also enables cost-efficient scalability by utilizing unused storage capacities across the network. Incentive mechanisms, such as token-based rewards, encourage node participation, further strengthening the system's reliability. Use cases include secure data sharing, archival storage, and sensitive information management for industries like healthcare, finance, and IoT.The proposed system demonstrates the potential of blockchain-based storage to overcome the vulnerabilities of traditional approaches while providing a secure, scalable, and transparent platform for data storage and management.
