They do meet the purity standards, that’s the point.
A better idea would to put a public key on each gold bar so that anyone can verify the authenticity. The producers could then compile a list of all the current locations of the gold and if someone tries to report a new inconsistent location, flag it as a fake.
- moviuro 7y agoI didn't understand that from the article. I understand that while counterfeits are getting better, they are still not perfect imitations. > “The level of counterfeit is becoming really good. Even for us it is hard to tell,” said a Swiss refinery executive who spoke on condition of anonymity. “They are, however, slightly less pure because the people doing the counterfeits don’t have the equipment we have.” For point 2, that's not going to work (copy-paste that key on another bar + zero anonymity or privacy protection + no protection if fake bar is introduced when real bar is out in the wild (in my backpack for example)).
- gwbas1c 7y ago> A better idea would to put a public key on each gold bar so that anyone can verify the authenticity Specifically: - Each gold bar has a unique ID, on the bar - A digital signature is made with the private key - The digital signature is placed on the bar - Everyone has to "know" which public key belongs to who (If you put the public key on the bar, then the criminals will just generate their own keys or copy someone else's key.)
