Chain Punks: 10,000 on-chain ASCII collectibles. Humans, robots, skulls and aliens. CC0.

Each punk is a face: a 21 by 13 grid of characters in Facemono, our cut of jgs5, set on black. A face has a type, then a head, eyes, a nose, a mouth, hair, facial hair, clothes, a hat, glasses and extras drawn from pools with Punks-style rarity: 177 attributes in all, some on thousands of punks, some on a handful.

Male 5,895 · Female 3,902 · Robot 130 · Skull 57 · Alien 16

No one draws a Chain Punk. A number does, and the contract keeps every rule it follows.

01 · The number becomes a genome. Hashing it gives thirty-two bytes. Nothing else is stored: this is the whole punk. 02 · It is drawn in eleven layers. Cloth first, then the head, and on to the hat. Each layer paints over the one before it, which is how a hat hides hair. What comes out is 21 by 13: 273 cells, each holding one character or nothing at all. 03 · Every two bytes choose one layer's option. The colour is part of the option's name, so Long Blonde and Long Dark are two options with their own weights. 04 · The chain draws it, and the seed hands it out. tokenURI builds the name, the attributes and the image inside the contract, as an SVG with the font embedded.
