I see no value added by using "blockchain" buzzword for a centralized system like this. It isn't even privacy protecting. This is an obvious use case for 1) some kind of database/book entry system, centralized, if you don't care about anonymity or 2) blinded Chaumian tokens, if you want anonymity (which has security/risk model costs)
