I feel like, for any application of the technology, there needs to be widespread interest and not targeted usage. With a small number of parties interested in processing transactions, you'd likely end up with one entity with too large of a share to make the system trust-able.

I haven't heard anything about that French management school, but "Marseille-Management-School-Coin"(TM) sounds like something only that French Management School would be interested in processing transactions for. You end up taking their word on it - which you would otherwise so using blockchain doesn't provide any benefits and is just a gimmick.

What you'd need is a large number of schools processing transactions for DiplomaCoin(TM), which then guarantees trust to a degree larger than any one (or two) of the entities could achieve alone.

And then, you have scaling to worry about. What is super annoying about this use case is that schools have a large number of students all graduating simultaneously 3 times per year (end of fall, spring, summer semesters). So there's the concern of overloading the system at those times.

And it sounds like a lot of the examples have the same problem of a single or very few parties interested in processing transactions -> blockchain is only a gimmick for these examples.

I think inter-bank lending would be a good use, lots of interested parties, not too many transactions.

EDIT: Looked up the number of students who graduate per year, it's 3.5 million. If we assume the 8 transactions/second standard then it would only take 5 days to process those. I think that's reasonable - although I'm not sure what universities could achieve in terms of transactions/second.

EDIT2: ~3.5 million/year for US schools alone, for all associates/bachelors/masters/doctoral.
