Launched a few days ago, CryptoKitties is basically like an digital version of Pokemon cards but on the basis of the Ethereum blockchain. And like most viral sensations that catch on in the tech world, it’s blowing up fast.
Built by Vancouver and San Francisco-based design studio AxiomZen, video games is the latest fad in the world of cryptocurrency and likely soon tech in general.
People are spending a crazy quantity of real money on the game. So far about $1.3 M has been transacted, with multiple kittens selling for~ 50 ETH( around $23,000) and the “genesis” kitten being sold for a record~ 246 ETH( around $113,000 ). This third party site ways the largest buys made to date on video games. And like any good viral sensation costs are rising and fluctuating fast. Right now it will cost you about. 03 ETH, or $12 to buy the least expensive kitten in the game.
So now we have people use Ether, an asset with arguably little tangible utility- to purchase an asset with unarguably zero tangible utility. Welcome to the internet in 2017.
In all seriousness, it’s a little bit reminiscent of the beanie baby tendency where people were paying insane sums of money for stuffed animals. But if the popularity continues to increase these people may be able to make a return by reselling or breeding their rare kittens, or they’ll be stuck holding the virtual cryptographic keys to a virtual rare kitten when the market accidents in a few days, like eventually happened with beanie babies.
There are a few cool things about video games though, and putting aside the valuation absurdity it’s actually a cool style for novices to interact with the Ethereum blockchain.
First off, it’s important to understand that since it’s played on the Ethereum blockchain there’s no central entity managing the game. This means users literally own their kittens. Unlike playing Neopets where everything was stored on a central database and your pet was deleted when the company shut down, CryptoKitties is decentralized and will live forever on the Ethereum blockchain.
The game is run via a define of five Ethereum smart contracts written by AxiomZen, and users interact with it via their own Ethereum address. Right now the easiest way to do that is by using the Chrome extension MetaMask which gives you the ability to send and receive Ethereum immediately in your browser. You then would navigate to the CryptoKitties site which is essentially an interface to interact with their smart contracts so you can buy sell and breed kittens.
Right now about 15% of all Ethereum network traffic is dedicated to the game, attaining it the more popular smart contract on the network. For reference, number two with about 8% of network transactions is EtherDelta, the popular decentralized token exchange.
This traffic is making it hard to play CryptoKitties, and a lot of transactions( like buying and selling cats) are taking longer than usual to process and requiring multiple attempts.
Not merely is this making it hard to play the game, but this scaling issue is a real fear for the Ethereum network in general. If one viral game that hasn’t even spread beyond the tech world can slow down the network, what happens when the blockchain expands to real world applications?
Anyways, back to the game. Still confounded? Us too. Here’s an explanation of how it runs 😛 TAGEND
How to Play
The game was seeded with 100 “Founder Kitties”. There’s also one new “Gen 0” cat released ever 15 minutes, which are listed for the average price of the last five sold, plus 50%- but the sale price declines over 24 hours until someone eventually buys it.
And anyone can sell their kittens via an auction, where they pick a starting cost and an ending cost and the cost deteriorations over hour until person buys it. So for example I could set a kitten up for sale for a one day auction for 1 ETH starting cost and 0 ETH ending price, and if anyone buys it 12 hours after the auctions starts they’d be paying me. 5 ETH.
Kittens can also be created by breeding them, which the game calls Siring. You can put your own kitten up for sire for a specified sum of ether and someone can breed with it, and they get the offspring and you get the ether. Or, you can pay to breed your cat with someone else’s and you keep the offspring and they keep the ether.
It can take anywhere from an hour to a week in “cooldown time” to breed a new kitten. The shorter the time the very best, since you can sell the progeny sooner and breed again. This means kittens with shorter cooldown time usually sell for more.
Each kitten has a 256 -bit genome that holds the genetic sequence to all the different combinings kittens can have. These include things like background color, cooldown time, whiskers, beards, stripes and so on. Some of these genes can be recessive, meaning a kitten without stripes could still breed one with stripes.
It’s important to note that there’s no “rare scale” established by the game that assigns rarity values to these genetic sequences. That entails the community is independently deciding what traits are rare by paying a premium for them. For example, kittens with a gold background have been selling more than kittens with other colors.
Users can only self-customize the name of their kitten, and often use this space to advertise rare attributes like coloring or generation.
Right now there’s no way to assure the actual genetic sequence for a kitten on CryptoKitties’ site, but since it’s all open-source code within an Ethereum contract it’s merely a matter of time before someone figures out how to “read” your cat’s genetic sequence and make breed recommendations based on it. There’s also some randomness built in, which keeps it fun by giving someone with a less rare kitten the chance to breed a rare one.
Each time a cat breeds the generation increases one. So the progeny of a Gen 0 kitten would be a Gen 1, and so on. Earlier generation kittens seem to be selling for more fund, both for the intangible rareness factor and the tangible fact that earlier generation kittens usually have shorter cool down times.
Axiom constructs money by maintaining the ether collected from selling the initial 100 kitties, plus the newly made kitties sold each 25 minutes. They also take a 3.75% fee of all auctions or siring transactions. If you sell a kitten by interacting directly with the smart contract( and not going through CryptoKitties’ website) you wouldn’t have to pay the 3.75% fee.
Unlike some viral projects, the team behind CryptoKitties was set on constructing out this product regardless of this hype. Mack Flavelle, the project lead for the game to present to me that the team has at least a year’s worth of product improvements in the pipeline, the most immediate of which is improving the UI on the web platform.
They also want to work to stimulate the on-boarding process easier, because at the end of the working day it’s still not easy for the average person to setup MetaMask and figure out how to buy ether and use it to transact on the network.
The project has a pretty good FAQ here which explains a bit more about the game’s future plans and how it works today.
