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.

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 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.

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).

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

Stay safe Luis!

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!

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

Quote

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!

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.😉

This is probably a stupid question but:

Is it possible to use Baby-step giant-step algorithm to mine Bitcoin? Like is it possible? Since this algorithm runs in peta/keys, we can use this for mining and easily bruteforce 19 bits and get to find a correct hash for the blockheader and get easy 100k euros.

If not possbile, why not?

Thanks

As albert0bsd said, they are not the same.

But I wanted to figure out how you figured, "for mining and easily bruteforce 19 bits..."?? 19 Bits? 19 bits would only be 4 leading zeros. The latest block is 00000000000000000006b68d2acbb26adbe3f0ffe653ec08cb3469b3729dda59; that is 19 leading zeros or 76 bits. Big difference.

No is not possible, because mining is just bruteforcing the sha256 until get some zeros in the begging of the resulting hash, it can't have any math shortcut.

hello albert did you manage to adapt keyhunt for a GPU version ? which should be faster

No. However, depending on what you want to use, BSGS, Search for private keys, Kangaroo, etc. there are existing programs that incorporate GPUs. Example, BSGS = BSGS Cuda; Kangaroo = Kangaroo by JLP. For searching for private keys, there are many GPU options.

I am looking for a bsgs GPU version with random which reads an incoming file not in sequence. I used before this one
https://github.com/Etayson/BSGS-cuda
but it doesn't offer random and read incoming file in sequential not random. On the other hand, on a single PubKey search, its speed can reach 2 ExaKey/s VS 82 PetaKey/s (KeyHunt) for me for the same search.

There is also KeyHunt-Cuda available, but it's not from Alberto as far as I know

i know it take milions years heh but it is good range ?

Half of the keys are in that range (actually is the half of the whole range)
