Decentralized certificate issuance and verification system using Ethereum blockchain technology

Abstract

The increasing prevalence of fraudulent and inefficient centralized certificate systems poses significant challenges across various sectors, undermining trust and hindering efficient verification processes. This paper aims to overcome these difficulties by offering a decentralized certificate issuance and verification system based on Ethereum blockchain technology and Goerli testnet. It is developed to provide a reliable and transparent way to create and validate credentials in various industries (for example, education—offering a transparent and non-tamper proof validation of academic credentials; healthcare—allowing for the secure validation of medical education; government—speeding up the validation of official documents). Our solution then uses the unique features of decentralized blockchain technology to remove the need for a central authority, closing off an entire attack vector of fraud and the misrepresentation of businesses, which opens the door to greater global trust and security when it comes to digital credentials. Certificate information is securely stored within smart contracts on the Ethereum blockchain, enabling automated verification processes for enhanced efficiency. Tested on the Goerli testnet and incorporating a user-friendly mobile application, our approach offers a robust and scalable solution for certificate management, promising to revolutionize credentialing processes across diverse applications and ensure enhanced security and trustworthiness for future digital ecosystems.
