Non-fungible token is what it stands for. It's a digital asset constructed on a blockchain, just
like the token definition above. The term 'non-fungible' simply means that it is one-of-a-kind
and cannot be replaced. A4R is fungible, for example, since 1 A4R can be switched for another.
They are the same. We're working on A4R NFTs, which are one-of-a-kind tokens that reflect
movement achievements, avatars, artwork, and more, and may be sold.
