We are all witnesses to @dmtnatcats 
Culture. Cats made by Bitcoin, fully on-chain and non-arbitrary.​
Provenance. The first digital art collection generated by the Bitcoin blockchain based on the principals of Digital Matter Theory (DMT).​
Rarity. Less than 1% of all Bitcoin blocks to date have generated a Natcat (8k / 875k+ blocks).​
Aesthetics. Each Natcat has uniquely defined color combination determined by its Bitcoin block number. The collection includes many rare and specialized traits based on specific patterns.​
Evolving. The Natcats collection autonomously evolves at a timescale that will outlive all of us. Potential future generations of Natcats may emerge as certain properties appear on-chain.
