CryptoKitties is a blockchain-based pet raising game, which includes cat breeding, collection, purchase, sales, etc. It is also called “pat your cat online ” and “cyber cat petting “.
Although there are many virtual pet games in the history of the Internet, this CryptoKitties cat is probably the first virtual pet in human history that users can permanently own. Traditional virtual pets will be placed on the company’s server that provides services. When the company closes, the virtual pets will disappear.
With CryptoKitties, your ownership will be distributed to the entire Internet through smart contracts. It cannot be copied or destroyed. This digital asset can be stored, circulated and traded in any Ethereum blockchain system.
How popular is the CryptoKitties?
Since its launch in November 2017, CryptoKitties has accumulated more than 1.5 million users, with a total transaction volume of more than 40 million U.S. dollars.
Just a few hours after going online, it occupies more than 15% of Ethereum’s network and contributes 30% of Ethereum’s transaction volume, directly causing the congestion of the entire Ethereum network, which shows the high popularity of the game.
Some of the most popular cats sold for more than $200,000. In terms of its sales, a day’s transaction volume can exceed one million dollars, which is almost a killer application.
In December 2017, the game even caused Ethereum congestion. During the peak of the hype, CryptoKitties had 1.5 million users and contributed $40 million to this transaction. “Dragon” is the most expensive cat, which is priced at 600 pounds ($170,000).
Each CryptoKitten is a non-circulating token and adopts the ERC-721 token standard, so that it can be stored, created and sent using smart contracts. The ownership of cats, which is irreplaceable tokens, can be traced back. Because every transaction will be written on the blockchain such as the change of the owner! However, ecosystems generally charge very little fees.
The rise of CryptoKitties has made more people notice the new world of blockchain games. And more traditional game industries have seen the dawn of their rise, which also opened the door to the hot development of blockchain games in the future.
