You forgot to mention the even/odd inverse function. The problem is still open.
Not a single brightest mind on this planet can find the solution. Otherwise one would know the keys to satoshi treasures.
Pesonally I do not compete on who will introduce the best C++ or GPU program.
For me the main interest is in learning new things. Programming itself is a good way to keep the mind spinning.
Of course pity for those who think that someone will publish here some code that will make them rich overnight.
Especially funny I find here those saying that they can find here nothing interesting and introducing themself as experts of some kind.
The best thing for them would be to join some pro cryptographers and math geeks forum to find new ideas there.
But they hang around reading every thread to prove to themselves that they can find here nothing. Some pretty odd situation.

It's not enough. I need his exact address. Phone number etc. 

Perfect, that narrows it down. Its either Steve from Estonia or Dave from Albania.

Yes my friend you are right. In many platforms, everyone is full of free code, dreams of getting rich.
Many of the people who want to show themselves as EXPERTS have become famous only with the answers given through AI (Artificial Intelligence).
I do not think that people who are cryptographers or math experts will want to come here. Because here, a person who comes will immediately encounter trolls or people who give similar answers, so they will not come.
Actually the subject is very simple, as the creator said.
"Testing the power of society." But many people I see do not deserve to be a society or a group.

When someone uses AI all day long, they'll only see everything as AI in their life, to the point they can't even make the difference any longer.

I guess big companies really pay some people very good money just because they can simply prompt some GPT to spit out skills, which definitely aren't what an above-average folk with higher degree studies is ever capable of. In fact, why should anyone actually think anything any longer? That sounds useless!

Hooray to GPT. Someone please inform all companies and universities to get rid of all of their employers, teachers, Why waste so much money when you have GPT? just keep the handy man, I don't think AI can clean off the dust or wash the floors yet. Not until Elon ships out his grocery buying robots at least. In fact - just shut down all operations, and sell the buildings. GPT can handle everything, from nursering your baby, to satisfying your spouse while you're busy binging 3 Body Problem (which was written, filmed, post-edited. and automatically distributed globally by an AI, obviously; no humans involved, why would that be needed at any stage?). Oh, and all the "actors" were CGI - no one needs humans to do that kind of job. It's wasted money.

I recently forked your Cyclone and added a couple of tweaks Now with -bit and -subzeros for Fine-Grained Private Key Range Control.

-bit – lets you select the bit length for the random private key range (e.g. -bit 71)
-subzeros – lets you define how many trailing hex characters (zeroes) the range should have.


This will generate a key range like:




You can adjust the number of zeroes based on your CPU thread count and brute-force capability.

I’m planning to build or buy a more powerful CPU setup (under $2k), and I’d love some suggestions from the community on CPUs with strong multi-core performance suitable for this kind of workload.

Any recommendations are appreciated!

Then why waste time doing it?
I was thinking of raising up your inexistent merit from zero to 1 for "I am no longer sharing any ideas or thoughts here.". That's a good decision after 233 zero-valued posts! But then I remembered how it's impossible for you to ever admit your mistakes.

Hope the other 135 people are aware that their fascist leader can't count bits properly, while calling everyone else (who haven't yet ignored him) as AI disfunctional idiots.

Which one you do you think it’s gonna be solved: 71 or 135? Maybe one year later?

I noticed that some people in the group are searching for prefixes of the Bitcoin address:

1PWo3JeB9jrGwfHDNpdGK54CRas7fsVzXU

For example: 1PWo3JeB, and so on.
Can anyone with experience explain the reasoning behind this?

It doesn’t make sense to me, since the private key is what gets incremented, and each key generates a completely different Bitcoin address.

What am I missing here?!!!

The purpose is jump between prefixs for reduce scanning, but the problem is the distance between prefixs target is not same because the distribution is not predictable.
this the example of scanning with sequential, you can see the distance is can't predicted. Even when we use average distance but that not guarantee the calculation not skipped the puzzle target.
