Silk Road black
A Silk Road sat that is also the last sat of its block: a black sat inside the bitcoin sold at the first Silk Road auction.
How a sat qualifies
A sat is a Silk Road black when it is both a Silk Road sat (inside one of the Silk Road list's 405,534 ranges) and black: the last sat of its block. The category's definition is sr_1st_auction and black together.
Silk Road sats were mined in 50 BTC and 25 BTC blocks, whose last sats are all last sats of a whole bitcoin, so every Silk Road black is also a Silk Road omega. The first is sat 11,899,999,999,999, the last sat of block 2,379, which is also a Kilosat black. Rarity tiers are exclusive, but none of the Silk Road blacks is a black rare or black epic.
Sat 999,834,999,999,999, the last sat of block 199,966, is in the Hitman list as well: it is a Hitman black too, and sold on its own it is filed under that rarer category.
Silk Road black is the one place-and-black pairing that the index's tracking rules name outright (black with sr_1st_auction among its required combinations); Pizza and Hitman blacks are tracked because every black sat is.
