Process

4.The smart contract returns a transaction ID

5.Student gives this transaction ID to company for verification

1.University uploads the certificate on IPFS

2.IPFS returns a unique hash

3.University uploads hash and student details on blockchain via smart contract

6.Company retrieves the IPFS hash from the blockchain via the smart contract

7.Company puts the IPFS hash on IPFS

8.IPFS returns the file whose hash has been provided

Output





University putting information of student and the certificate’s hash

Function for company to get the IPFS hash by the transaction ID
