Which of these assets is non fungible?

A. A twenty dollar bill
B. A 1 kg package of peanuts
C. A drawing of a stickman drawn by a five year old in kindergarten
D. A copy of The Mona Lisa

Explanation

An asset is non fungible if there is only one of it. The kid's drawing is unique and more valuable than those of other kids to the kid's parents. But one twenty dollar bill is as good as another, one package of peanuts is as good as another, and while The Mona List itself is unique, a copy of it is not.

Are NFTs transferrable?

A. No, never
B. It depends. An NFT representing a certificate of completion of a course of study likely to be transferrable. An NFT representing ownership of artwork is likely won't be transferrable.
C. It depends. An NFT representing ownership of artwork is likely to be transferrable. An NFT representing a certificate of completion of a course of study likely won't be transferrable.
D. Yes, always.

Explanation

Like any other asset on Ethereum, NFTs are managed by programs called smart contracts. The smart contract can be written to allow or disallow the transfer of the NFT, depending on what the NFT represents. It makes sense to allow people who buy artwork to sell it later. However, an NFT that represents an individual achievement should not be sellable to people who did not achieve the same.

Can ownership of an NFT be revoked?

A. No, never
B. Only if the NFT is transferrable
C. Only if the NFT contract permits revocation
D. Yes, there is no way to make a non-revokable NFT

Explanation:

NFTs are managed by smart contracts. If the smart contract includes provisions that allow for NFTs managed by it to be revoked, they are revocable. If it doesn't (and you can check that before minting or buying NFTs of that account), they aren't.
