A Digital Tattoo (or Digital Collectable), is a Non-Fungible Token, or NFT.
What is an NFT?
An NFT is a unique digital certificate stored on a blockchain that proves ownership of a specific digital item (like your tattoos).
Each NFT is one-of-a-kind, or one of a set series. They cannot be copied.
They have become popular in the art and collectibles world, allowing people to buy, sell, and collect digital items in a way that verifies their authenticity and ownership.
