I have tested 3 apps, BitCrack 625MKeys/s, VanitySearch-BitCrack 1024MKeys/s but the problem is it gets hang multiple times in a day and forced to restart my PC, and KeyHunt-Cuda 945MKeys/s with these settings (KeyHunt-Cuda.exe -t 0 -g --gpui 0 --gpux 950,256 -m address --coin BTC...)

I created this helper app, it has both the modes, auto or manual/personalized mode. In auto mode it first pick a random number and check if its it is already scanned or not and apply filters, if everything is ok it creates a command and pass it to new cmd and wait for the search to complete. It also has an option to divide the full rane in to multiple parts and search N number of ranges in each parts.

I suggest that you edit your helper code to search all 4 prefixes with the random generated number for (supposedly) higher chances
for example : generate a random hex 45BF0D0E4
search for 445BF0D0E4,545BF0D0E4,645BF0D0E4,745BF0D0E4

yeah seems it between sequintial - random style. Great idea.. hope you share it on git 😅🙏

If we all share each scanned section together, there will be more than prefix theory or the number φ.

Why overcomplicate things? You are talking about a pool. You can just join one.

I've been running puzzle 71 with keyhunt-cuda for 3 months and it feels completely hopeless.

I run 4x3080ti+ 4x3090 kangoroo puzzle 135....
3x 3080ti vanity bitcrack all  random puzzle 71
2x4080 super for prefix experiment 😅
Already 4 month no luck 😅. Hope good luck next month.

I'm scanning with a GPU using BitCrack at a speed of 550 million keys per second. I searched the key range from 78D110000000000000 to 78D12BDB2A82C14000 over a period of six months.

What is your search method that allows you to scan the vast key space of Puzzle 71 within one week?
