Keyhunt - development requests - bug reports

On github I found that  '' Almost all bitcoin addresses with a balance are in the 254-256 BITs range. ''

Is This True ? Best range is -b 256 ?

It is a probabilistic distribution bit 256 is the Half of the whole key space, bit 255 is a quater and bit 254 is have a 12.5% of the whole range, if you add those values it is 50% + 25% + 12.5% that is 87.5%

How did you come up with those numbers? 256 is two times of 255, and 255 bit is x2 of 254 bit. Searching in 2^256 decreases the chance of finding a single address/key by 2^96. I just haven't figured a way to only search 160 bit range in order to get all com/uncompressed keys. Let me know if you do.😉

Hi everyone.

I just want to say a very thank you to the persons who donate to my address, this last 14/Feb somebody just gave me e about 3000 USD, I really don't expected that this days Because lately I have not been very active, besides that I have been a little unmotivated

Anyway, as I wrote in my github page https://github.com/albertobsd/keyhunt#donations

All the donations will be use only for two things:

Native Windows version with 0 external dependencies.
Get an affordable desktop computer with decent GPU, not highend, just to start the GPU version.

I will try to cashout those donations to my local currency in the next months, i need to figure it how to do it without lossing anything in taxes or fees. Once that i cash that money i will try to buy a desktop computer to work in some updates that i've thinking, also the start to work in a GPU version.

I actually don't know who was that person, to the person who donate that without notifyme  if you want please send me a signed message with that addess just send you any update in the code.

Again thanks.

Best regards!

[citb0in]

I was not the donator, but I want to express --> you deserve it!   keep up the the good work and your YT content

[dextronomous]

Hi there man, keep it up, good works on you always,
wish it was me who donated. you deserve big time.

greets

[GR Sasa]

Awesome! Thanks for the donator. We wish to get a GPU version of this awesome machine keyhunt with a powerful speed! <3
Goodluck to all!

[GR Sasa]

I am so happy that you were abe to cash out! I hope you can now buy a GPU 
Stay safe Luis!

I would like to suggest that you should keep your identity hidden from the public, after all you are working on something which has a potential of endangering billions of dollars investments.

No longer possible after the spat between him and MikeJ_NPC (go to the reputation board for details on that - I won't provide any commentary here).

First name should be fine, but I would leave it at that. I don't want anyone to get robbed after all.

I would definitely avoid revealing street address or even the name of the city however. It helps a lot.

Edit: Alberto I just used your keymath program to implement a multithreaded key division program in C++, thank you very much for the work that made it possible (and to GMP for having a modpow function).

Albert0bsd doesn't even have huge amount of bitcoin available on his wallet... Why should be he scared? Even for people who threaten him, they are just probably kids behind the screens. There is nothing to be worried of.

I did my program for puzzles and I recommend to everyone stay in puzzles. I need to add a disclaimer in the github repository

Yes i know that now, in the bad way...

There is nothing to be worried of.

Thank you, yes there is nothing to be worried because I didn't anything.

By my mental health i prefer not talk about that topic anymore.

By the way, i just found a way to double the current speed of keyhunt in BSGS mode, it need a lot of changes in the code i will work in that soon.

[GR Sasa]

Thank you, yes there is nothing to be worried because I didn't anything.

Exactly.

Wow, that's awesome!! Thank you so much Alberto! You are one of the few geniuses left that are still active programming new things.
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, because we also want to be like you  

Maybe if we manage to make BSGS a little bit more faster, added GPU to it, we could probably hit puzzle #125 with small chances. Who knows. It's luck in the end using Random.

[albert0bsd]

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

That amount of experience is enough to make you a professional (for context, I have about half that amount), but it seems that CUDA is becoming something of an Achilles heel for me, not because of the lack of hardware or anything but because the GPU chip is so fundamentally different from the CPU.

OMG, Alberto guess what? I just discovered a new formula to attack 3 targets at the same time, there is a way to break ECC, SHA256- and RIPEMD-160 in one try, here is the procedure:
We perform *RIP-160 on public keys, and save the resulting addresses or just their hashes, and then we go after finding just one of them and when we find that one, we'll have a SHA-256 and a RIP-160 collision, but unfortunately that would break the ECC as well. Though in order to demonstrate how serious this attack could be, for the involved parties in development to see and think about the solution, we need to do this with all our forces combined.

So to everyone let's pool our shitty hardware together in order to prove our point, who is with me? Lol.

*= we should call it that, "Rest In Peace" soldier from now on because we are here.🤣

I seriously didn't understand anything. What are you talking about?  Please don't join this forum if you're drunk.

Also, i think you have a little knowledge about how Bitcoin works

Thank you

[albert0bsd]

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:

Code:

Publickeys->address->(search here)

What he proposes is something like:

Code:

Publickeys->(search here)->rmd160->(search here)->address->(search here)

But if you already have the publickets of your target then is more easy:

Code:

Publickeys->(search here by xpoint or BSGS)

Transform your publickeys to rmd160 search

Code:

Publickeys->rmd160->(search here by rmd hash)

[digaran]

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?

If I could reach Tk/s speed, it would be a giant leap for my research, is there any windows version?

[GR Sasa]

Dear albert0bsd, We need as soon as possible a GPU version of Keyhunt  puzzle 125 stands at 12.5 bitcoins now! This is a LOT OF money!

With as less as the lowest puzzle,(66), i can finally actually buy home now

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.
