Any two CryptoKitties can be bred, and an offspring with its distinct features is developed via a genetic algorithm (or “cattributes”). Using smart contracts and ERC721 tokens, CryptoKitties was created to evaluate the notion of digital scarcity.Įach and every CryptoKitty has its digital genome, stored in a smart contract. ERC721 enabled the development of non-fungible, one-of-a-kind tokens. Before the introduction of ERC721, blockchain tokens were fungible or interchangeable every Bitcoin or Ethereum token is identical to any other.
Users have already purchased almost USD 1 million worth of virtual pets just a few days after the introduction.ĬryptoKitties are Non-Fungible Tokens (NFTs) created using the ERC721 token standard on the Ethereum network. The game was so popular after it was released that it clogged the Ethereum network with so many transactions.The first Cryptokitty, Genesis, was sold for 246.9255 ETH, valued at around USD 117,712.All Cryptokitty transactions are done in Ether because the app was created on the Ethereum network. These virtual cat assets are held on the Ethereum blockchain, which uses smart contracts to allow gamers to buy, collect, breed, and sell their virtual cats.
