The NFTs aren't really needed though, a manufacturer could just have a "scan this item with your phone to see if it's genuine" app and that would be sufficient.
Again, the problem of a centralised ledger comes back.
- jfim 5y agoWhy would it? If brand X adds anti counterfeit detection in their products and makes a brand X validation app, what's the added value of the ledger?
- subhro 5y agoAs we have seen, apps decay over time. So someone has to keep track of the app. Also, given unlimited time, all cryptographic algorithms can be brute forced, especially something that has the same key for all hashes. So, now you have the problem of maintaining a key for your "counterfeit detection", and somehow get older keys revoked. Do you see a ledger now?

- TchoBeer 5y agowhy does our counterfeit detection need a key?

- catlifeonmars 5y agoI don’t think centralization is a universal problem. In many cases (one could argue the majority of cases), centralization is not an issue.
