I beelieve puzzle 71 will be the final tough challenge to crack, boasting an impressive total key count of 1,180,591,620,717,411,303,424
Solo pooling seems the way to go. I'm considering forming a private group, as I’m wary of existing solo pools,if you catch my drift. The group would have a system where members share their scanned ranges, but stats would only be visible to those who contribute at least 20 range scans.
How do we verify contributions? Simple!members provide keys for specific addresses within their range.
Does this setup sound solid? I think it’s a fair, efficient way to tackle the puzzle, ensuring the lucky winner earns it through a level playing field while avoiding duplicate efforts and wasted resources.
After analyzing the puzzle, it’s clear the creator initially used Mersenne’s law and XOR for earlier puzzles but switched tactics later. I’ve tried every approach to replicate earlier results and came to one conclusion: the creator likely selects addresses from specific ranges, though it’s hard to accept. I’m unsure if this is the work of an individual or a group.
It’s evident they anticipated attempts to crack the formula, so they leaned on randomness to keep it unpredictable. So, @Bam, don’t waste your time with analysis, the only way forward is to think like the creator: is the key at the beginning, middle, or end?
