Hash One Collection

Hash Ones” were the first-ever generative art collection minted on Stacks, secured by Bitcoin. They were designed for testing the network and our early Stacks NFT marketplace functionality. Each Hash One is just 21kb in size and was sold for just 1 STX each. Only a handful of Hash Ones were released each day.

Due to high demand and the limited capacity of the nascent Stacks network at the time, each batch of 5 Hash Ones released caused several hours of network congestion. During a 48-hour event, the original #1 contract was upgraded, resulting in only 91 Hash Ones being minted out of an edition of 111 in September 2021.

In March 2023, the 20 remaining members of the original collection found another historically notable home on the Bitcoin Blockchain. They were inscribed as Ordinal NFTs, bridging two major technological moments in the story of Bitcoin NFTs.
