Right, but think about what happens if there’s some question – say you ran for office and your opponent says you’re lying about your degree or GPA.

People will trust the institution – if a reporter calls them and they say “yes, they earned it” most people will not question it. If they say “never heard of them”, a record on a blockchain won’t help much because it disagrees with the canonical source and then you’ll be hearing about how that degree record was published in error or fraudulently, or that school is a diploma mill, etc.

Electronic records are nice but a 1970s public key signature works just as well at a fraction of the cost because ultimately it comes down to whether or not the reader trusts the issuer.
