Abstract: ABSTRACT The present invention relates to a blockchain-based academic certificate validation system with offline-verifiable cryptographic proof for secure and tamper-proof verification of academic credentials. The system comprises a certificate issuing authority module, a certificate hashing engine, a blockchain-based credential registry, a cryptographic proof generation engine, an offline-verifiable QR code generator, and a verifier application. Academic certificate data is digitally signed, hashed, and anchored on a blockchain ledger to ensure immutability and authenticity. A verification proof package including certificate hash, Merkle proof, issuer digital signature, and blockchain checkpoint metadata is embedded into a machine-readable QR code. The verifier application validates the certificate offline using preloaded trusted issuer keys and blockchain checkpoints without requiring internet connectivity or centralized server access. The invention provides decentralized trust, privacy-preserving verification, forgery prevention, revocation awareness, and efficient credential validation across educational and institutional environments.
