Non-fungible tokens (NFTs)
What's an NFT, you ask? Well, it's there in the name. In contrast with ERC-20, network currency, or other fungible, currency-like tokens, non-fungible tokens are meant to be unique. There may be a series of them, but they are not interchangeable, one for another; each one is different. For this reason, they have been the subject of amazing innovation and creativity since the inception of Ethereum mainnet; one of the first big surges of usage and adoption of Ethereum was through CryptoKitties, an NFT-based videogame in which players breed and collect unique cats, each one of them tokenized as an NFT.
