NFT stands for non-fungible token. It gained popularity in 2021 (Kireyev, 2022). NFT can be any digital file. These files can be tracked with the same blockchain technology as the crypto-currencies such as Ethereum and Bitcoin. This procedure gives sellers and buyers a clear record of the ownership of their files.
Each NFT is digitally unique. People can copy an image but original file ownership remains secure. This procedure is similar to showcasing your artwork in a museum. You can buy a print of it for yourself but can’t take the original piece back home.
