Total number of addresses that start with the same 11 characters = 2^66 / 58^(11 * log2(58))
First, calculate 58^(11 * log2(58)):
58^(11 * log2(58)) ≈ 58^42.614 ≈ 1.2107 × 10^74 (approximately)
Then, divide 2^66 by this result:
2^66 / 1.2107 × 10^74 ≈ 460708775.52
So, the approximate number of addresses that start with the same 11 characters from a key length of 2^66 bits is about 460,708,775.
This made me laugh out loud.
Where did 10^74 come from?
You realize 10^74 is larger than 2^66, correct? Not by a little but a lot.
Thanks for the laugh though! I appreciate it.
