Nakamoto palindrome
A sat from one of the 19 Nakamoto blocks whose number reads the same backwards, such as 45,000,000,054 in block 9.
How a sat qualifies
The row's definition is Nakamoto and palindrome: a sat in one of the 19 Nakamoto blocks whose decimal digits read the same in both directions.
How many palindromes a block holds depends on how many digits its sat numbers have and how many of their leading digits are fixed. Block 9's sats (45,000,000,000 to 49,999,999,999) have 11 digits, and a palindrome is set by its first six, so block 9 has 50,000 of them (Block 9 palindromes); block 286's have 13 digits and it has 5,000 (Block 286 palindromes). The other 17 blocks add theirs to the total below.
Examples: 45,000,000,054 (block 9) and 1,430,000,000,341 (block 286).
Why collectors care
A Nakamoto palindrome is a single sat with a symmetric number, from a block the site attributes to Satoshi Nakamoto. The set is fixed: the blocks are fully mined.
