How is it different from a centralized database that also stores and tracks ids of their products? A lot of companies that have to deal with scammers counterfeiting their product were using these methods even before blockchain was invented. And what would stop scammers from doing the oldest trick in the book - copying the identifier of a genuine item and slapping it on their fakes?
But I guess a centralized database can be edited by an insider when it comes to blockchain it can't be which maybe the key difference why they are going to implement blockchain for tracking their products but I don't really think they can stop counterfeit bottle by using this kind of track because consumer maynot be validating the products which they bought from a store with the publicly available ledger.
