NFTs (Patreon)

A non-fungible token (NFT) is a unique digital identifier that is recorded on a blockchain and is used to certify ownership and authenticity. They typically contain references to digital files such as artworks, photos, videos, and audio. Because NFTs are uniquely identifiable, they differ from cryptocurrencies (which are fungible, hence the name non-fungible token), and as a result they cannot be copied, substituted, or subdivided.[1] Their ownership can be transferred by the owner, allowing NFTs to be sold and traded.
