CryptoKitties is a game based on the Ethereum blockchain in which users can breed, collect, and sell kitties. Each cryptokitty is one of the kind and 100% owned by the user. How did happen that digital cats became so popular?
What is CryptoKitties?
Crypto Kitties is a blockchain game developed by a Canadian studio AxiomZen, that allows users to collect and breed digital cats. This is the first attempt to implement blockchain technology in the entertainment world. The game was the most popular in 2017 when the number of transactions on Ethereum was so huge that caused the overloading of the network causing it to reach an all-time high in the number of transactions and slowing it down significantly.
Users can associate with other Cryptokitties and also sell them. For example in 2017, Genesis the first and highest selling cat was sold for ETH 246.9255. There are a total 12 virtual kitties with different DNA and attitudes (including pattern, mouth shape, fur, eye shape, base color, accent color, highlight color, eye color), users can give their characters selected traits, breed, and then sell them.
Cryptokitties – how does it work?
Cryptokitty’s ownership is tracked by the smart contract on the Ethereum blockchain. Each of Cryptokitty is represented as a non-fungible token based on the ERC-721 token standard. It is a limited number of cats going into circulation and their limited genomes are about 4 billion in common. Cats are tokens on the blockchain, so they can be bought, sold, or transferred digitally, with strong guarantees of ownership. A CryptoKitty does not have a permanently assigned gender. While they can only engage in one breeding session at one time, each cat is able to act as either mother or father.
The path to the success
People spend a lot of money on the game, So far about $1.3M has been transacted, with multiple kittens selling for about 50 ETH (around $23,000) and the “genesis” kitten being sold for a record about 246 ETH (around $113,000).
Cryptokitties as a game based on the blockchain have few big advantages, which wouldn’t be possible in a traditional app probably.
We need to pay attention that it’s played on the Ethereum blockchain. There is no central authority managing the game, so certainly users are owners of their CryptoKitties. There is no central base, where your data will be stored. CryptoKitties is decentralized and will live forever on the Ethereum blockchain.
The game is run via a set of 5 Ethereum smart contracts, and users interact with it via their own Ethereum address.
Right now about 15% of all Ethereum network traffic is dedicated to the game, making it the most popular smart contract on the network. For reference, number two with about 8% of network transactions is EtherDelta, the popular decentralized token exchange.
CryptoKitties became really viral, which is the best confirmation, that blockchain technology can be successfully used to provide entertainment.
