Akito did you modified the FixedPaul's code to specifically search in 71bit range and another thing i want to ask is, like nodemath code he is searching for prefix f6f543, if someone is able to find multiple of these prefixes in the range, will it help in any way to reach the target faster?
If you are at least close to f6f5431d25bbxxx h160 it can help with some calculations. In low bit matching, too many possibilities come out and it becomes difficult to calculate the result.
Well my closest hit are f6f5431d25bbe1b97, f6f5431d25bbd7cab and f6f5431d25bc0ce6. I know its not spread evenly but at some places you get some sort of distribution and I do agree with your theory, at some places it works but at some places its just random. If you would love to share what you found out new in the last few days, will be great to add something to my knowledge. And for those who doesn't believe in this, please let us beat around the bushes. It doesn't hurt with a single machine with 1x 3090. Thanks.
