Block 666
Any sat mined in block 666, sats 3,330,000,000,000 to 3,334,999,999,999. Its alphas, omegas and palindromes are tracked one by one.
How a sat qualifies
Block 666 paid a 50 BTC subsidy, 5,000,000,000 sats. At 5,000,000,000 sats per block, its sats are sats 3,330,000,000,000 (666 × 5,000,000,000) to 3,334,999,999,999. Every sat in that run is a Block 666 sat. Block 666 lies in the vintage range (blocks 0 to 999), so its sats are vintage too.
Why collectors care
The site names it by its height alone: its description is just "Block 666". It is one of the few single early blocks the site names on its own, with Block 9, Block 78 and Block 286.
What is tracked
Unlike Block 9, Block 666 is not tracked whole: the index follows only its sats that are special on their own, in three rows:
- Block 666 alpha: the 50 sats that start one of its bitcoins.
- Block 666 omega: the 50 sats that end one.
- Block 666 palindrome: the 5,000 sat numbers in it that read the same backwards.
Its first sat (3,330,000,000,000) is an alpha and also an uncommon; its last (3,334,999,999,999) is an omega and also a black sat. A plain Block 666 sat that is none of these is in no Block 666 row, and there is no Block 666 collection of its own.
How many
All of these are mined.
