Thanks!
But I can multiply numbers.
Me the dimension of size MKey / s interests.
For example, 1 MKey / s - is how much the private keys are: 1, 10, 100, 1000, 10000, 100000, 1000000 or other meaning ?
Author can correct me if necessary, but I presume 1 MKey/s would mean mega-keys, ie it's trying 1 000 000 (one million) key combinations per second?
It's brute forcing so every raw private key attempt has to be mapped (through public key generation plus hashing) to an address.
