# Hashmasks

> Hashmasks is a collection of 16,384 unique digital portrait NFTs on Ethereum, created by 70+ global artists and launched in January 2021. Each mask is a one-of-a-kind artwork with on-chain traits (background, character, mask type, skin color, eye color, item, glyph). Holders earn 10 NCT (Name Changing Token) per day and can burn 1,830 NCT to permanently name their mask on the blockchain — one of the first on-chain identity mechanics in NFTs.
