So here’s a legitimate question because I haven’t seen it asked before. Whats the value of a paper “certificate of authenticity” at the moment. My understanding is that with art if you can tie it to the original issuer, then it has value. And indeed I know there is some fraud law around forging such things. So NFTs seem fairly well suited to provide hard to forge art provenance with minimal effort.

They also seem well suited for being able to transfer ownership of physical goods and also transfer things like warranties. With an NFT tied to a serial number, you could ensure only one owner with that serial numbers item can claim warranty coverage, ensure resellers don’t try and pass off something used as new, ensure stolen goods can be tracked as such, etc.
