As with many things it's a solution, then again you can achieve the same result much more easily in other ways - it's just a reference number lookup after all.

I’m not convinced that will work or that it’s an optimal solution, but I do think it’s a novel use of blockchain tech rather than a buzzword inclusion.
Awesome, so we can waste terawatts of power on a blockchain solution when there are plenty of other ways to do this. Just because blockchain is the current funky go-to technology doesn't mean it is the best tool to do the job.
One would hope that it would not be as bad as the crypto currencies as there is no need to "mine" but blockchain is a solution looking for a problem.
