NFT

NFTs (or “non-fungible tokens”) are a special kind of crypto assets in which each token is unique — as opposed to “fungible” assets like Bitcoin and dollar bills, which are all worth exactly the same amount. Because every NFT is unique, it can be used to authenticate ownership of digital assets like artworks, recordings, and virtual real estate or pets.

In other words a very "unique product" you and I own, sell, and create. See what we are working on here:
