What is a non fungible token?

A non fungible token (NFT) is another form of digital asset. This asset can be exchanged with other NFT token that are similar.  Similar NFTs could be art, music, or photography.  The idea is that you can monetize your craft by putting it into a block chain.  This ensure that the original author and original say art is one of a kind.  NFT art can be worth a lot of money and usually the intrinsic value of NFT art is tied to the popularity of the artist who produces it and how well known they are.
