Nonfungible tokens (NFTs) are cryptographically unique digital assets created on a blockchain (and often linked to a digital file stored off-chain such as the IPFS).
NFTs have exploded into mainstream popularity with major celebrities and public figures such as Jack Dorsey, Elon Musk, and Lindsey Lohan, and Beeple selling art, tweets, and a variety of other digital creative works as NFTs on platforms like Foundation and Rarible.
