Do you remember CryptoKitties, the virtual cats that collectors spent thousands of dollars to buy on the blockchain? They seem to have been merely the forerunners of the currently faddish non-fungible tokens (NFTs). In essence, any digital asset that a creator wants to make unique can be turned into an NFT (digital works of art, music, sports moments, and even tweets) and monetized. The NFT acts as a non-duplicable digital certificate of ownership; it will be stored on the blockchain and can be bought and sold like any piece of property. While the digital asset itself will still exist on the Internet, only the buyer of the NFT can call himself the owner of the “original” asset. As such, NFTs can be a financial investment, a sentimental purchase, or a collector’s item. NFTs can even contain smart contracts that, for instance, give the creator a cut of any future sale of the token. Although opinions on NFTs vary, once the hype around the space settles down, the idea of tradable digital assets will be here to stay.
