How Does Verifier Works?

• The Certifying Authority registers the authorized certificate on eSealer.
• The eSealer calculates a hash value using a Secure Hashing Algorithm (Cryptography) and send it to Edubuk's smart contract (indexed) on the mainnet of blockchain to store the record.
• The Verifier takes a Certificate file, calculates it's hash value and send it to Edubuk's smart contract on the mainnet, which takes this filehash and searches for that hash value.
• If the hash value is matched with a value stored with the Edubuk's Smart Contract on the mainnet, then a verified record result is shown in green color.
• But if the certificate is either tampered or forged: whose record is not present on the blockchain, will get an error in red color.
• If a certificate record is shown to be Verified, you can also lookup for the exact Institute/College/University who was the official "Certifying Authority" by mapping the address of "Certificate Issuer Account" using the "Certificate Issuer Lookup" button, provided above.
