Decentralized Document Storage with NFT Authentication Using Blockchain Technology

Abstract

This research introduces a solution to escalating data security and privacy concerns by utilizing Ethereum-based blockchain technologies, like Polygon, and NFTs for decentralized document storage and authentication. Unique NFTs associated with each document are cryptographic proofs, minted and recorded on the blockchain to ensure resilience and tamper resistance. This research experiments with the use of Solidity based smart contract along with a decentralized file storage protocal, IPFS, to enhance flexibility and scalability.
