For students, the benefits go beyond mere novelty. They can share their diplomas almost immediately with whomever they please, free of charge, without involving an intermediary. This is particularly important for students who need to prove to an employer or another university that they have an MIT diploma. And thanks to the blockchain, the third party can easily verify that the diploma is legitimate without having to contact the Registrar’s Office. Using a portal, employers or schools can paste a link or upload a student’s digital diploma file and receive a verification immediately. The portal essentially uses the blockchain as a notary, locating the transaction ID (which identifies when the digital record was added to the blockchain), verifying the keys, and confirming that nothing has been altered since the record was added.
