We propose a decentralized system for issuing and verifying marksheets securely using smart contracts on the Polygon blockchain. Each marksheet is hashed and recorded on-chain, and each certificate includes a QR code that enables any stakeholder (such as students or employers) to verify it instantly without relying on a central authority. The architecture consists of a web-based issuance portal, on-chain smart contracts, and a QR-driven verification interface. We describe the complete workflow from entering student data into the portal and generating QR codes to executing Polygon transactions and performing hash-based authenticity checks—and we demonstrate how the system supports efficient bulk issuance of credentials. Comparative analysis shows that this approach eliminates the forgery and delays common in traditional paper or PDF transcripts, offering a tamper-proof and transparent alternative.
