Centasat uncommon
The first sat of every 100,000th bitcoin: a sat number divisible by 10,000,000,000,000 but not by 100,000,000,000,000; each opens a block.
How a sat qualifies
Sat s is a centasat alpha when s is divisible by 10,000,000,000,000 (100,000 bitcoin of 100,000,000 sats) but not by 100,000,000,000,000. It is an alpha at a round number of bitcoin.
A sat has exactly one milestone tier, the highest: divisible by 100,000,000,000,000 is megasat, else by 10,000,000,000,000 centasat, else by 1,000,000,000,000 decasat, else by 100,000,000,000 kilosat.
The first is sat 10,000,000,000,000, the first sat of block 2,000.
Why "uncommon"
The fork's type is centasat_alpha; the site labels it Centasat uncommon, one of Uncommon's rarest sub-categories. Every one of the 189 is the first sat of a block:
- 187 are plain uncommon;
- 1 is rare: sat 1,680,000,000,000,000, block 504,000;
- 1 is epic: sat 1,050,000,000,000,000, the first sat of block 210,000 and of the second halving epoch.
The category matches by type, so it holds all 189; the rare and the epic one are never counted as Uncommon.
Its pair
The sat just before each one is a Centasat black, with the same milestone tier (both are worked out on the same round number). The site's pair rule counts a Centasat black sold with a Centasat uncommon as part of the uncommon's sale.
