MOONCAT.CENTER
Every MoonCat was generated with a proof-of-work strategy similar to how Bitcoin is mined.
This hashed out a string of code that defined the artwork.
Out of the billions of combinations that could have been generated, the 25,440 MoonCats that were rescued were individually selected by their minters.
These are the first non-fungible tokens minted with a fully decentralized process, through an algorithmically randomized event, that required significant interaction for each mint. MoonCat Rescue is a curated collection of generative artwork that is entirely stored on Ethereum. Verified as a preeminent digital collectible asset developed using blockchain technology.

For each MoonCat, the minter pointed their computer's processor to mine a string of code. The traits of a specific MoonCat were randomly generated by this event. The output was a set of hexadecimal units that created a MoonCat's seed value.
The visual representation of the seed value was rendered, and the string of code could be put in to the smart contract function to mint that specific MoonCat. Or they could execute the mining task again to create a new seed value.
The traits of each MoonCat were set by the parameters in this seed value. This converted into the CatID when the non-fungible token was minted to the blockchain.
There are a set of rules, built into the smart contract, that allow for expressing the hexadecimal CatID as visual artwork.

The traits of 0x00ff4cf92c can be discovered by reading the CatID.
