After years of being a museum novelty, digital art is starting to sell like hotcakes--and in some cases for millions of dollars--because of a crypto asset called nonfungible tokens, or NFTs. And it isn't just art--sales of digital collectibles of all kinds are benefiting from these blockchain-based certificates of authenticity. NFTs are making the market more accessible for artists, but in the future, they also could disrupt the entire economy of the art market.
