The proposed system is based on e-certificate system in India’s educational framework that leverages blockchain technology to address the widespread issue of certificate forgery. The inherent qualities of blockchain, including its immutability and transparency, create a solid foundation for enhancing the security and reliability of educational certifications. The operational framework is built around creating and storing an electronic file containing essential academic information in a dedicated database. Concurrently, the system generates a unique hash value for this electronic file, which serves as an exclusive identifier. This hash is securely embedded within a blockchain block, benefiting from the technology’s resistance to tampering. To enable verification processes, both an inquiry string code and a QR code are linked to each certificate, encapsulating necessary information for authenticity verification. Users can initiate validation by scanning the QR code with a mobile device or entering the inquiry string on a specific website. The hash stored in the blockchain is then checked to confirm that the certificate has not been altered. This proposed solution significantly enhances the credibility of traditional paper certificates by implementing a dependable, transparent, and tamper-resistant verification process.

This paper presented a blockchain-based framework for secure e-certificate generation and verification. By integrating cryptographic hashing, QR codes, and smart contracts, the proposed system effectively prevents certificate forgery and unauthorized modification. The decentralized and immutable nature of blockchain ensures long-term credibility and trust in academic credentials. Experimental evaluation confirms that the system improves security, efficiency, and reliability compared to traditional certificate verification methods.
