Centasat black
The last sat of every 100,000th bitcoin: a sat s where s + 1 is divisible by 10,000,000,000,000 but not by 100,000,000,000,000; each closes a block.
How a sat qualifies
Sat s is a centasat omega when s + 1 is divisible by 10,000,000,000,000 (100,000 bitcoin) but not by 100,000,000,000,000. It is an omega at a round number of bitcoin.
A sat has exactly one milestone tier, the highest, worked out on s + 1: megasat, else centasat, else decasat, else kilosat.
The first is sat 9,999,999,999,999, the last sat of block 1,999 (also a 1D palindrome).
Why "black"
The fork's type is centasat_omega; the site labels it Centasat black, one of Black's rarest sub-categories. Every one of the 189 is the last sat of a block:
- 187 are plain black;
- 1 is black rare: sat 1,679,999,999,999,999, the last sat of block 503,999;
- 1 is black epic: sat 1,049,999,999,999,999, the last sat of block 209,999 and of the first halving epoch.
The category matches by type, so it holds all 189; the black rare and black epic ones are never counted as Black.
Its pair
The sat right after each one is a Centasat uncommon of the same milestone tier. The site's pair rule counts a Centasat black sold with a Centasat uncommon as part of the uncommon's sale.
