CryptoPunks is a non-fungible token collection with 10,000 unique characters stored on the Ethereum blockchain and were the inspirations for the ERC-721 standard that powers most digital art and collectibles. It was launched in June 2017 by the Larva Labs studio, a two-person team consisting of Canadian software developers Matt Hall and John Watkinson. It was acquired by Yuga Labs including Meebits and gives commercial rights to the community.
The CryptoPunks are 24×24 pixel art images, generated algorithmically. Most are punky-looking guys and girls, but there are a few rarer types mixed in: Apes, Zombies and even the odd Alien. Every punk has their own profile page that shows their attributes as well as their ownership/for-sale status.
