Blockchain-based certificate hash verification system
Upload certificate and store its hash on blockchain (University only)
Upload certificate file to verify its authenticity on blockchain
University stores hash: Upload certificate file, system generates SHA-256 hash and stores it on blockchain
Hash stored permanently: The hash is stored immutably on the blockchain, no one can modify it
Anyone can verify: Upload the same certificate file to verify if its hash exists on blockchain
Tamper-proof: Even a single character change in the certificate will result in a completely different hash
