I was reading about RINs or Renewable Identification Numbers on Wikipedia here:
https://en.m.wikipedia.org/wiki/Renewable_Identification_Number
And it said that since RINs can be bought and sold, there has been RIN fraud. Lately there has been talk of NFTs or non-fungible tokens in the newsmedia and I thought that since these have the ability to uniquely identify something, they could be used to uniquely identify RINs. I don’t know that much about NFTs and blockchains so I’m not sure if it’s possible. But I know that the RIN could be given a public cryptographic key and the private part of the key could be given to the government so that the RIN can later be uniquely identified. If someone sold a fake RIN it could be submitted to the government for confirmation that it was a valid RIN. More information.
