UPC is a product code (what it is).
Bunnie's blockchain code is a serial number that is (theoretically) impossible to guess or fake. This prevents scammers from guessing/faking serial numbers to scam him out of product.
- Cacti 9y agoSorry, I didn't mean UPC, I meant serial number. You can generate unique, nearly impossible to guess serial numbers using all kinds of methods without any need for a blockchain.
- cracell 9y agoA UUID would work fine. Every product gets a UUID and it goes into a public DB hosted by the manufacturer (or a 3rd party that verifies who is publishing the data). Then anyone can query against that database to verify if a product is legitimate.
- antsar 9y agoWouldn't counterfeiters scrape that database for legitimate UUID's? You could allow consumers to "claim" a UUID as theirs (and when I get a product with the same UUID, I can assume it's a dupe), but that requires every consumer to actually do this...
- Scoundreller 9y agoMake it difficult to scrape? At the end of the day... we know these things get leaked anyway...
- cracell 9y agoYes. I did not think it through well enough.
- Cacti 9y agoThe proposed blockchain solution also requires users to register.
- IncRnd 9y agoExcept that a blockchain is the exact wrong technology to use here. Look at Bitcoin, for example. That blockchain is entirely controlled by manufacturers in China. How would this blockchain viably guard against manufacturers in China? Besides, the blockchain or other storage mechanism is irrelevant. All the counterfeiter needs to do is copy the serials or other numbers from the blockchain or wherever they are stored. These methods all make it easier to pass-off a counterfeit as legitimate.
