NFT stands for Non-Fungible-Tokens. Fungible assets are interchangeable like money, non fungible assets are unique and not interchangeable.
Crypto’s fungibility adds trust when conducting transactions on the blockchain.
When producing NFTs, a digital signature is added to the token, making it impossible for NFTs to be exchanged. NFTs live in the Blockchain and identified by unique data. NFTs are kept on the Blockchain, and because of this, NFTs are easy to find and identify. This tracking allows for verification of their authenticity as well as their past history and owners. This is very important on art pieces because it negates forgery.
