Decasat uncommon
The first sat of every 10,000th bitcoin: a sat number divisible by 1,000,000,000,000 but not by 10,000,000,000,000, nearly always a block's first sat.
How a sat qualifies
Sat s is a decasat alpha when s is divisible by 1,000,000,000,000 (10,000 bitcoin of 100,000,000 sats) but not by 10,000,000,000,000. It is an alpha, the first sat of a whole bitcoin, 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. A decasat is never also counted as a kilosat.
The first is sat 1,000,000,000,000, the first sat of block 200.
Why "uncommon"
The fork's type is decasat_alpha; the site labels it Decasat uncommon, one of Uncommon's rarest sub-categories, because these sats almost always open a block. Of the 1,890 there will be:
- 1,874 are plain uncommon;
- 13 are rare, such as sat 252,000,000,000,000 (block 50,400);
- 1 is epic: sat 1,575,000,000,000,000, block 420,000;
- 2 fall mid-block: sat 2,098,000,000,000,000 in block 2,110,400 and sat 2,099,000,000,000,000 in block 2,320,400.
The category matches by type, so it holds all of them. A rare or epic one is in Decasat uncommon and in Rare or Epic, never in Uncommon.
Its pair
The sat just before each one, s - 1, is a Decasat black: its tier is worked out on (s - 1) + 1 = s, so the two always share a milestone tier. The site's pair rule counts a Decasat black sold with a Decasat uncommon as part of the uncommon's sale.
