Using Kangaroo i can solve every puzzle till 100 bit in very short time (of course im talking about puzzles where public key is available). Till 70 bit it's almost immediatley.
The problem is the range is getting exponetnially bigger to the extent it's just too big for current hardware (at least available for home users).
If you can handle 100 bits, why don't you solve puzzle #130? If I had that power I would have already found it.
Cause estimated time for solving 100bit i have in DAYS while estimated time for 130bit i have in HUNDREDS OF YEARS. This shows how massive is the gap between these two ranges. People seems to not realize that.
That's assuming you unlock directly using the publickey of puzzle #130, but certain techniques allow you to go from 130 to 100 or less.
You can go to 80, 64, 52, 12 or 1. Doesn't mean it's faster.
Just by reducing the bit range doesn't make it faster, without new code being able to run multiple pub keys at once, etc.
I really find it hard to believe, actually, I don't find it hard to believe, that within this community of people who follow these posts, we can't get enough people, that have a combined total of 500 GPUs, whether it's 500 people with 1 GPU each or 100 people with 5 GPUs each, or a mixture of people and GPU quantities...
But we can't get 500 GPUs to crack #66 in less than a year, if we had 1,000 GPUs, right at 6 months.
It's kind of funny, but not
The current 66 bit pool, that is running, is doing double the work.
I may do some tinkering over the next few weeks and set up some sort of pool, more than likely just keep it personal, because exposing servers to the public, there's always those 1 or 2 peeps who spend time trying to hack it lol.
Anywho, 500 GPUs = #66 found in less than a year.
