Re: How many CPUs/GPUs needed to crack Bitcoin Puzzle 71 and 135 in 1 day?
To keep things simple without going into technical details and exhausting calculations for
71
--> the range comprises 1180591620717411303423 addresses to be scanned. It all depends on where the target address is located in this range, but if we assume that it's at the end, it would take almost 2 million 4090 GPUs to reach it in 24 hours. If the target is in the middle of the range, let's say that 1 million GPU 4090s would suffice
with GPU 5090s, let's say that this number would require around 20% fewer GPUs, i.e. 1M5 or 750K
This is using Bitcrack or Vanitysearch, perfectly optimized for the system used.
For the 135 it's different insofar as the pubkey is available, the tools and speed are also different, but the difficulty is just as great. RetiredCoder's RCKangaroo, which was perfectly optimized for its configuration (i.e. over 12GK/s for the 130é), took 2 months to achieve this using 400 GPU 3090s, with the target at 62% of the range. In 1 day, we would have needed almost 60 times as many 3090 GPUs, say at least 24,000 RTX 3090 GPUs.
For the 135th, the search space is more than 30 times larger, so we'd need at least 750k GPUs 3090 to get there in 24 hours, if the target is 60% of the range, using software perfectly optimized to run on such a configuration.
Whether it's the 71st or the 135th, the difficulty of getting there is roughly the same, even if the software or the way of doing it is different, since for one the pubkey is known. We wish you good luck.
