i just read it i don't quite understand what your getting please go further in detail. not to be rude.
well, you seem very confident and optimistic about what are you saying, and that is good actually we need people with good optimistic. If you dependent of the reply of some website then what avoid to the website to found a puzzle? What I am tryting to tell you is that this kind of programs need to generate the keys on the fly without depend of anything else. I recomend to you to read the informacion about how keys are generated. https://www.oreilly.com/library/view/mastering-bitcoin/9781491902639/ch04.htmlAlso wha are you saing to store that data? that is complety unnecesary, the keys need to be generated and checked on the fly without store anything. Best regards!

Before I lose my mind, can someone please tell me, why is generating public keys and comparing them with target can reach Tk/s, but adding just a sha256 and a rmd160 could reduce the speed to Mk/s? I thought EC calculation was the hardest part of key generation process, is it not?
The difference is that with publickey you can apply Bsgs algorithm (you can do arithmetic operations with the publickey that are directly linked with the privatekey) And the problem with hashes is that you can't do those operations ( well you can add them or Subtract them but the result is not linked to anything not publickey or privatekey). About windows version i recommend to use it on the WSL environment.

I was wondering, have you guys ever seen a wallet to generate a private key consisting of only decimal numbers without a single hex character? Well I haven't, and it is the case with only hex chars as well, so is there any way (possible way) to skip brute forcing all hex, all decimal keys and just search through the mixed keys? And what would happen to our search range if we could eliminate such keys, as in how many keys could we skip brute forcing? Isn't that an idea worth exploring?
In my case (keyhunt) and I think that it is a general case, hexadecimal is only used as output only for "friendly" representation. Internally the program works with decimal numbers a.k.a. "Big number" variable like mpz_t (from libgmp) or Int for (libsecp256k1 library). So it should be the same performance.

i know that, and thats what im talking about men , its located in the range of 200.. to 3fff.. if you find same 7 or 8 digits of the rmd160 that means its in that range bro, so, when i post the public key substracted from 125 to 110. i told you this is in the 110 bits because it start with the 4 same rmd160 of other wallet in 110, that means its in the same range of 110, like you said bro in 66 20d45a6a same start of wallet 66, and the range is 319afc.... so, do you understand what im talking ? I don't understand anything, the start string of the address don't have any relationship with the range

However, just because someone else creates/makes something that may be faster, doesn't mean it can't be. I bet albertosd would tell you his BSGS program is faster than JLPs, I think he has a video on it, I think.
Yes my version of BSGS is a little more faster because the bloom filter use less memory than the hash table. This debate between GPU and CPU power need to be clarified. Obviously GPU Power is better than CPU. So to compare apples with apples, we need the exactly same program or algorithm to see how fast is one or another. The main advantage of CPU programs that use RAM as "booster" is that RAM for CPU can reach some 128 GB or some terabyte if you are testing it in some custom server. The GPU max Memory available is some 32 GB in some high end devices. That is why there aren't many programs like BSGS for GPU. So we can't compare an algorithm like kangaroo for GPU against some Custom BSGS with stride in CPU because in that case we are comparing apples and pineapples. (There is not point of comparation) Regards

He did spent puzzles 161-256 just like what others have suggested since those are absurdly impossible to bruteforce. That's about 3 months after the post.
Not forget to mention that he also increase the prize of the unsolved puzzles in a Factor of 10 just like he said. Relevant transactions ID of this challenge with link to the blockchain database:

how to reduce the search range of 125 to 120 ? what range i put for substract the public key of 125 to smaller range ? 0:1f>>>>> ?
there is no way to narrow it down with 100% certainty, In the best case the complexibility is the same, in the worst case the complexibility is sometimes worse. I've trying so many methods and none of then give you some certainty.

Also, i think you have a little knowledge about how Bitcoin works
He knows more or less what he is talking about. I think that method will be some inefficient, if you already have the publickeys i think that is better homologate the search to an only one Kind of search, all by Xpoint or rmd160 or addresses Current search for address is this: Publickeys->address->(search here)
What he proposes is something like: Publickeys->(search here)->rmd160->(search here)->address->(search here)
But if you already have the publickets of your target then is more easy: Publickeys->(search here by xpoint or BSGS)
Transform your publickeys to rmd160 search Publickeys->rmd160->(search here by rmd hash)

Can i ask you, how long did it take to you to be this good at C/C++? How did you practice? A little tips would be so good for us
I learn to develop C, twenty years ago,. But some of those years I didn't develop or practice anything. I just learn some others computer languages. So I only have some 5-6 years of experience in that language. About tips, learn to do algorithms and flowchars for computer programming. Search for the regional and mundial ICPC problem set and solve it in less than a 24 hrs (Those algorithm problems are made to be solve in 3-4 hrs). I am just an average programmer, well that is what I think, i have some problems finding a good job, maybe I am part of those who knows something well enough to know all things that I don't know, aka dunning kruger effect

Hi @zielar, nice to see you here 2. Someone has a tool to find #125 soon
As we know the puzzle 125 is 32 times bigger than puzzle 120 but prize is only a 4% bigger, i doubt about that such "magic" tool exists. But we don't have way to know. If that exists it should be a mathematical approach. I made some computations. Used Python 3. I was curious if the next puzzle can be ax+b=y. d1, d2, d3 are corresponding private keys from puzzle. Needed to compute a and b.
We already know that puzzles a random and there is not math relationship between them
