NFTs are “minted” from a digital object representing tangible or intangible items, including music, art, collectibles, videos, etc. So NFTs are like a digital form of collectible items, which only allows one owner at a time. The exclusive ownership rights are recorded on the blockchain so that no one can change them. The owner or creator of NFT can also store specific information, such as including the artists' signature in an NFT’s metadata. Since these collectibles hold value, they can be bought or sold like other forms of art.
