4156, often referred to as Punk4156, is an anonymous investor, NFT collector, and artist who claimed fame early in the NFT space. He is known as both a CryptoPunk maximalist and for being the owner of one of the most coveted Punks in existence: CryptoPunk #4156. Although 4156 changed his position on CryptoPunks over the years and eventually sold his famous Punk, he has continued to be active in the space. In fact, he even took on a new identity. He is now known as the creator of the fantastically popular Nouns NFT project and brand. 4156 is also a vocal supporter of NFTs being licensed under Creative Commons (CC0), which gives collectors full rights to duplicate, brand, market, and use the intellectual property contained in their NFTs as they see fit. All in all, 4156 is considered a major champion of Web3, NFTs, and digital ownership.
