To be sincere, using the blockchain to validate university certificates will be a brilliant option. Most universities require a transcript when studying further and the essence of a transcript is to validate that the student certificate was given by tbe institute. With the use of a distributed ledger, there will be no need for a transcript showing you are from institution A with a particular grade and going to further education at institution B. All the university needs to do is juat comfirm with the blockchain.
