An NFT is a Non-Fungible Token. The token refers to a digital token or certificate that is stored on a secure distributed database referred to as the blockchain. NFTs are therefore unique digital assets that can be bought and sold, with every transaction being permanently recorded in the blockchain.
One way to think about NFTs is that they are like a certificate of authenticity that is permanently embedded into a database, along with any future transactions that transfer ownership. You can see who minted the NFT, who bought it and so on, in perpetuity. NFTs are a new technology, and we are only seeing a small portion of their likely future potential.
