What does this mean? You will give the step by step instructions on how to solve, before the outgoing transaction?
SHA-256 of correct solve steps (will publish tomorrow at this time)
Most likely, the sha-256 hash is simply a hash of the text that contains instructions on how to correctly convert a public key to a range of 80 bits an so on.
All I know it was supposed to be 80 bits, anywhere in what was posted, so to me, you could post something like this:
0xa6c39217128593909a1fcc0fd92c07a6f5abd32c36a8e7cf4e91f1a8f0651db0
and that would be enough.
The difficulty of this challenge is that some people don't understand where the 80-bit range is, some don't understand how to convert a public key to the required range and return the resulting private key to the 512-bit format and vice versa.
This is just part of the challenge.
