I agree, one can’t easily tie an NFT to a physical object. Nothing guarantees that the watch and NFT change ownership in tandem.
All I’m saying is that a serial number doesn’t really prove anything because it’s trivial to copy. A private key inextricable from the object would be better, because it could generate timestamped signatures as proof.
- lolinder 5y agoBut whatever you use would still be easier to implement using traditional tech than web3, because the problems they solve are orthogonal.
- pshc 5y agoYes. I regret not being more clear in my original comment, because the scheme I alluded to is an application of public key cryptography, such as Certificate Authorities, and is not about cryptocurrencies specifically.
- meheleventyone 5y agoEven with time stamped signatures you can clone the signature onto a fake watch.
- pshc 5y agoThe point of a signed timestamp (and/or challenge string) is that it demonstrates the signature is freshly generated, proof that the device is authentic right then and there. An old copied signature would not have this property.
