c843n is a Tezos-based generative art project by the artist Kim Asendorf, who releases one-of-one and small-edition works under algorithmically generated, hash-like titles. Individual pieces such as 17758f72c69 and 17cafadb477 have circulated as editions of three, sold in Tezos (XTZ).¹ The project's series FRATZE — German for grimace or grotesque face — strips the profile-picture format down to stark, monochrome studies of the human face.²
