This research project investigates the enhancement of data security and scalability in a decentralized document storage and verification system by implementing a private Geth node with a Proof of Authority consensus mechanism. The study introduces AES Symmetric encryption to protect documents stored on Kubo IPFS-Cluster and employs HTTPS to secure client-server communications, ensuring robust data security during transactions. The system allows issuers to upload and hash documents securely on the blockchain, enabling recipients to retrieve these documents using unique identifiers, while validators can authenticate document originality by matching hashes within the blockchain. The document storage system using blockchain explores into the Ethereum blockchain and IPFS scalability intends to uncover and incorporate optimizations to boost performance, with the overarching goal of significantly advancing the security and efficiency of decentralized document management systems. The system's architecture, security features, and scalability solutions, demonstrating the potential of blockchain technology in enhancing the integrity and accessibility of document management are the deliverables.
