Abstract: A Decentralized Storage Network (DSN) that combines blockchain technology with peer-to peer (P2P) communication to enable secure, tamper-proof file storage across distributed nodes. This system ensures data confidentiality and integrity by splitting files into encrypted chunks, redundantly storing them across the network, and recording storage commitments on an immutable blockchain ledger. This System achieves P2P distributed storage system which does not have single point of failure, and tamper-proof file storage with intuitive design and ease of access. The data chunks are duplicated and stored on multiple nodes for fault tolerance and leveraging Proof of storage consensus for Security and Validating Nodes and rewarding them. This network include a lightweight Merkle root-based transaction validation mechanism, UDP hole-punching for NAT traversal, and AES-256 encryption for data confidentiality.
Keywords: Decentralized Storage Network (DSN), Blockchain-based Storage, Peer-to-Peer (P2P) Networking, Tamper-proof File Storage.
