NFTs, or "non-fungible tokens", are in the news a lot these days. They either pumped up as the next big thing or being dragged down as a dumb idea that was destined to fail.

Here's the thing: despite it's very non-catchy name, an NFT is simply a way of owning or collecting a digital asset AND having a certificate of authenticity built in. If you were a sports card collector you would want your Babe Ruth baseball card to have some proof of authenticity saying it's real, it's an original, etc. An NFT does that digitally on a global behind-the-scenes database called the blockchain. 

While some say the NFT market is slowing down (or worse, evaporating) I can't imagine the need or desire for individuals to seek out uniqueness and ownership of digital assets going away. Music, art, avatars, design, writings, etc. All could be "trademarked" with an NFT. Otherwise, the risk of publishing something digitally is that it can saved unlawfully, counterfeited, pirated. An NFT helps to prevent that.
