More broadly, an NFT allows to establish the “provenance” of the assigned digital object, offering indisputable answers to such questions as who owns, previously owned, and created the NFT, as well as which of the many copies is the original. So, what’s an NFT? An NFT is a unit of data stored on a blockchain that certifies a digital asset to be unique and therefore not interchangeable, while offering a unique digital certificate of ownership for the NFT 3. Overall, in the first four months of 2021, the NFT volume has exceeded 2 billion USD, ten times more than the entire NFT trading volume in 2020 2. While NFT adoption in gaming has already reached a certain maturity, for example concerning the trade of in-game objects, different other industries, especially those involved with the production of digital content such as music or video, are experimenting with the technology. The revolution is not confined to the art market. “WTF are NFTs? Why crypto is dominating the art market” is the title of the Februepisode of The Art Newspaper podcast 1, signalling both the impact of Non Fungible Tokens (NFTs) on the art world and the novelty they represent for most of the general public.

We anticipate that these findings will stimulate further research on NFT production, adoption, and trading in different contexts. Finally, we investigate the predictability of NFT sales using simple machine learning algorithms and find that sale history and, secondarily, visual features are good predictors for price. Third, we cluster objects associated to NFTs according to their visual features and show that collections contain visually homogeneous objects. Second, we build the network of interactions, show that traders typically specialize on NFTs associated with similar objects and form tight clusters with other traders that exchange the same kind of objects. First, we characterize statistical properties of the market. Here, we analyse data concerning 6.1 million trades of 4.7 million NFTs between Jand April 27, 2021, obtained primarily from Ethereum and WAX blockchains. Public attention towards NFTs has exploded in 2021, when their market has experienced record sales, but little is known about the overall structure and evolution of its market. They are traded online, often with cryptocurrency, and are generally encoded within smart contracts on a blockchain. Non Fungible Tokens (NFTs) are digital assets that represent objects like art, collectible, and in-game items.
