Secure Certificate Management using Blockchain Technology

Abstract Certificates are crucial in daily life, serving as proof of academic achievement or professional qualifications. However, verifying these documents is often slow, complicated, and prone to fraud, with alarming numbers of fake certificates circulating globally. Such fraudulent activities, including academic certificate fraud, cost employers significantly and pose serious societal threats, particularly in critical fields like medicine. This paper proposes a transformative solution using blockchain technology to address these issues. Our system leverages a decentralized database where certificate records, stored as immutable blocks, are virtually impossible to tamper with. By integrating Ethereum smart contracts for secure record-keeping and the InterPlanetary File System (IPFS) for decentralized file storage, the system ensures secure, permanent storage of credentials, simplifies the authentication process, and significantly mitigates certificate forgery. The proposed methodology utilizes Solidity for smart contract development, Hardhat for deployment, and Ethers.js for blockchain interaction. Testing on the Sepolia testnet confirmed the system's effectiveness, demonstrating successful, immutable, and verifiable certificate registration transactions, proving its robust security and transparency.
