I managed to prove experimentally on 5 different computers that everything is in seed. You can speed up solving the puzzle by a million years if you know the correct seed. And the best thing is that you can always achieve the same result in the same time. Proof is in the pudding.

@nomachine after successfully proving to myself (I'm a bit behind the curve here) that anything I thought was a pattern/clue to solving this puzzle was just part of the maths inherent in the system, I'm now of the mind that this is correct... We can either try to brute-force the pkeys, and/or we can try to reverse-engineer (also by some amount of brute-force, I guess) and recreate the process by which the pkeys were created... Which is likely possible given that A) you appear to have done it at least once already for puzzle 50 above, and B) the person who claims to have created this said themselves that "It is just consecutive keys from a deterministic wallet"... That is, assuming the the words "consecutive" and "deterministic" apply accurately and weren't just used colloquially...

Anyway, I've looked through the code you posted (which I've snipped-out for brevity)... Is that python? I'm afraid IDK python... Which version are you using? 2.3 or newer, I assume? And can you explain more about what exactly is happening here:

Code:

#Random seed Config
#constant_prefix = b'' #back to no constant
#constant_prefix = b'\xbc\x9b\x8cd\xfc\xa1?\xcf' #Puzzle 50 seed - 10-18s
constant_prefix = b'\xbc\x9b\x8cd\xfc\xa1?\xcf'
prefix_length = len(constant_prefix)
length = 8
ending_length = length - prefix_length
with open("/dev/urandom", "rb") as urandom_file:
ending_bytes = urandom_file.read(ending_length)
random_bytes = constant_prefix + ending_bytes
print(f"[+] [Core]: {core_number+1:02}, [Random seed]: {random_bytes}")
random.seed(random_bytes)

...it looks like you start with whatever this is, a hard-coded byte string or something?

Code:

b'\xbc\x9b\x8cd\xfc\xa1?\xcf'

...and then you go on to read more, random bytes from some file on disk? As a Windows/C# guy, I just can't quite grok what's happening here Huh

Any help would be much appreciated Cheesy
