The increasing number of fake, forged, and tampered academic and professional certificates has become a major concern for universities, employers and verification authorities. Traditional certificate verification methods rely on centralized databases, manual checking, or physical document validation, all of which are slow, prone to manipulation, and lack transparency. This paper proposes a Tamper Proof Certificate Verification System using Blockchain Technology, designed to provide a secure, decentralized, and immutable platform for issuing and verifying certificates. The system architecture incorporates a web-based portal for certificate generation by authorized institutions, a secure blockchain backend for data storage using SHA-256 cryptographic hashing and smart contracts, and a public verification module that allows users or employers to instantly validate certificates by scanning a OR code or entering a unique blockchain transaction ID. The findings indicate that blockchain-based systems can successfully prevent certificate fraud, streamline verification processes, and provide a scalable solution for academic and professional credential validation.
