A list of commonly used CryptoKitties terms with their descriptions.

Birthing Fee - It costs significant gas fees to birth new kittens, so we charge users a birthing fee only to cover this cost.

Blockchain - A digital ledger in which transactions are recorded chronologically and publicly. CryptoKitties runs on the Ethereum network, which is a blockchain.

Breeding - When a mommy and a daddy CryptoKitty love each other very much… Users can breed their CryptoKitties, resulting in a CryptoKitten that may reveal new traits.

Bun In Oven - This indicates when a CryptoKitty is expecting offspring.

Cattributes - When a trait is expressed in the artwork of a kitty, that trait is called a Cattribute. Note that in certain patterns, not all colors may be visually expressed, but because the Cattribute tag with each color still appears on the Kitty’s profile, the Kitty is still said to have those Cattributes.

Cooldown Speed - After a CryptoKitty mates they need a bit of rest; you’ll see a “Resting” or “Bun in the Oven” tag on cats that have just finished breeding. A cat’s initial rest period length, the “cooldown period”, is decided by their generation, and it increases the more a CryptoKitty mates.

Cryptocollectibles – Tokens that represent non-fungible digital assets, like art or digital Kitties. They are not classified as cryptocurrencies.

Dame - Mommy Kitty. You do the math.

Ether - Ether is the cryptocurrency that is used on the Ethereum network, and is the currency CryptoKitties uses.

Ethereum - CryptoKitties runs on the Ethereum network. Ethereum is a decentralized platform for applications that run exactly as programmed without any chance of censorship or third-party interference.

Exclusive Cat - An Exclusive Cat is similar to a Fancy Cat, in that it’s born with special artwork, but instead of being bred these cats are created by the CryptoKitties developers.

Fancy Cat - Fancy Cats are CryptoKitties that are born with special artwork. They’re created when Kitties are born with a particular combination of traits.

Gas - Gas is the computational power used for a transaction to be written onto a blockchain. In order for a transaction to be approved by the Ethereum blockchain, one must pay a transaction fee to the miners who mine Ethereum transactions. You can set the gas price per gas unit used, which changes the cost of the transaction, but also the speed it will be written at. A transaction will use as much gas as is needed up to a user-defined gas limit. If the gas limit is reached, the transaction will fail (and no gas cost will be refunded).

Generation Number - Cats released by the CryptoKitties smart contract are always generation zero, typically referred to as “Gen 0”. When new cats are bred, they are tagged with a generation number one digit higher than the highest generation parent.

Genome - Each CryptoKitty has a 256-bit genome. This is the cat’s DNA, and where its genes are stored. The genome is written on the blockchain; it’s the most inherent part of what “makes” a Kitty.

Gift Kitty - If users are feeling particularly generous, they’re able to give cats to another user.

Gwei - 1/1,000,000,000 of an ether. Gas prices on the Ethereum blockchain are set in Gwei.

KittyVerse - The universe surrounding the CrypoKitties game, not necessarily created by the CryptoKitties team—in fact, KittyVerse elements often aren’t. They are usually products, add-ons, or tools built by the community to enhance the CryptoKitties experience.

Marketplace - On the CryptoKitties web app, this is where all siring auctions and sales of CryptoKitties are found.

MetaMask - An app that allows you to store ether and conduct transactions on the Ethereum network. Read more about MetaMask here.

Sire - If we had to throw labels around, this would be the daddy Kitty.

Siring Auction - Players can allow other players to mate with their CryptoKitties in what we call a Siring Auction. The price of the auction is set by the user who owns the cat for Sire, and the user buying access to that cat pays the auction price plus the breeding fee and then keeps the offspring.

Traits - Traits determine a Kitty’s visual appearance (except when the Kitty is a fancy or exclusive). There are eight basic trait categories including eye shape, pattern, base colour, etc. plus up to two additional categories (wild elements like daemonwings and environments like salty), with up to two additional categories yet to be discovered.
