Any two CryptoKitties can mate, and a genetic algorithm creates a child with its own special traits. Every single CryptoKitty is distinct and has a digital genome that is kept in a smart contract. Initially, the purpose of CryptoKitties was to investigate the idea of virtual scarcity by utilizing smart contracts and ERC721 tokens. ERC721 made it possible to create one-of-a-kind, non-fungible tokens. This changed with the introduction of ERC721. Tokens on blockchains were previously fungible, or interchangeable each Bitcoin or Ethereum token is the same as every other. How does Cryptokitties work?ĬryptoKitties are non-fungible tokens that were initially created on the Ethereum blockchain using the ERC721 token standard. Since its debut in 2017, CryptoKittes has been one of the most popular NFT games in the blockchain industry, with over $12 million in circulation. In fact, many players have made headlines by raking in sizable sums of cash from the simple act of selling kittens in-game.

This suggests that if you are a legitimate owner of a kitten, no one else will be able to claim it any longer. However, each in-game NFT cat has a unique feature that cannot be copied or destroyed. This game is built around the idea of digital scarcity.
