HACD is the first text, on-chain daily auction, mineable, PoW NFT and PoW generative art, native to the Hacash blockchain. It has a limited and scarce supply. HACD has unique features and art styles, and also serves as a store of value.

Each HACD consists of a unique six letter combination randomly generated from the 16 letters "WTYUIAHXVMEKBSZN", therefore there are 16,777,216 possible HACD in total.

HACDs are generated through mining and HAC bidding. The mining difficulty keeps increasing over time, allowing on-demand issuance up to a max of 58 per day. In theory, it would take over 800 years to produce all HACD through mining, but due to the mining difficulty exponentially increasing far beyond Bitcoin's, it's likely impossible for all HACDs to ever be mined.

Additionally, HACD is a PoW-based programmable art protocol, which supports various generative art rules to produce unique artworks for each HACD.
