## What Jamie wrote

I don't like the [World of Warcraft](https://worldofwarcraft.com) term that [Buterin](https://en.wikipedia.org/wiki/Vitalik_Buterin) uses to describe non-transferrable NFTs, but the idea is something that I’m very intrigued by and have been for a while. There are a lot of use cases that open up if you know that the NFT a user has was not purchased from someone else, but granted directly to them. Think certifications, diplomas, licenses. 

One way to do this that seems interesting to me is to look at on-chain activity for each NFT and validate that the issuer is the owner previous to the current owner. If there was another wallet in the middle, invalidate the NFT. So, if MNDMV.eth sent me my drivers license NFT, but then I sent it to someone else, it could be invalidated immediately. 

I also love that he highlights [POAPs](https://poap.xyz) in this article. It is one of my favorite crypto projects.
