TL;DR

Abstract
It is crucial to confirm the legitimacy of educational degree credentials, particularly when hiring new employees, since falsified paperwork can seriously disrupt operations and reduce productivity. Conventional verification techniques are susceptible to delays, mistakes, and data manipulation because they mostly rely on human procedures and centralized databases. A single, safe platform for smooth communication between issuers, holders, and verifiers is absent from these systems. This study suggests a decentralized, blockchain-based issuer validation and certificate verification solution to overcome these drawbacks. The approach ensures data immutability and tamper resistance by storing certificate hashes on the blockchain using Ethereum. Every participant in the network is represented as a peer node, including the issuer, holder, validator, and verifier. Even in cases when the certificate cannot be located, a hash-based search method drastically cuts down on certificate lookup time. According to experimental evaluation, the system provides quick, dependable verification and is economical in terms of gas use. The maintenance and validation of certificates is made safe, transparent, and effective by this integrated method.
