It's a trendy type of technology called a non-fungible token, or short just NFT.
Imagine
an NFT
as a
unique proof of
ownership
over something you can't usually hold in your hand — a piece of digital art, a digital
coupon,
maybe a video
clip.
Like
the digital art itself, you can't really hold an NFT in your hand, either — it's a
one-of-a-kind
piece of
code, stored
and protected on the blockchain.
