@WanderingPhilospher it seems that I can only write 1 PM every hour, sorry. So that's not going to work.

Anyway to answer your PM I'm 80% certain about the range. I created the wallet years ago manually and was dumb enough to use it!!

That said, I think I prefer searching for it myself. If you would like to help with the setup, where it's best to rent GPUs, what version of Kangaroo to use, etc happy to pay a fee. I hope you understand, it's too much BTC to just give away the public key on a forum!

Thanks!!

Understood.

You’ll have to use JLPs version. Using 256 GPUs, it solved a 110 bit key in under 3 days.

So 128 GPUs should solve it in around 4.5 days, 64 GPUs should solve it in around 9 days.

I’m not the one to ask about renting GPUs as far as best prices because I rarely rent any and only rented my first one about a week ago.

Hello,

How long does it take to find a key in the 2^110 range? I know for this challenge it was found on 2020-05-30? But 3 years past and surely this range can be searched much quicker now? Can someone give me a time estimate and hardware if we were to search realistically this range? I am asking because I might have an old address where the key could be in that range...but not sure. And I don't want to spend thousands on hardware without knowing approx. how log it twill take to search the range with Kangaroo.

Thanks!!!

Honestly, it all depends on your hardware.

With my new mod/speed increase, I could solve a 110-bit range key, using 64 GPUs in less than 3 days.

Obviously if you use more GPUs, you can solve it quicker, if you have less than it would be longer.

I would help, depending on how much btc is in your wallet. I couldn't help unless I could reimburse my costs, plus a little extra.

If you want to throw some cash at it, let me know. DM and we can discuss and work out specifics.

I am not sure how you perform elliptic curve cryptography (ECC) calculations on a GPU as CUDA GPUs do not currently support 128-bit integers. Could you please explain your implementation, preferably with some code?

First page, link to GitHub, go look at the code.

This program has already solved 2 keys, at 109 and 114 bits.

2 steps folding 512bits to 256bits reduction using 64 bits digits. According to the document, I found out that this is not the secp256K1 algorithm. I want to implement GPU calculation in Python. Do you have any sample code?

So are you saying that if somebody wanted to find the private key of a known bitcoin public key, then this program will not work?!

Hello I've started attempting to port this over AMD devices, HIP to be specific. Currently stuck on working out exactly what the asm instructions are doing via CUDA/PTX. I have been reading up on the amd gpu instruction sets but it's all pretty complex and vary alot from nvidia https://llvm.org/docs/AMDGPUUsage.html https://gpuopen.com/amd-isa-documentation/ currently utilizing a RX 6800 so that would be rdna2 arch.

I have been considering just not using inline asm at all for this project so we can support more different gpu models.

Any help at all for this project would be greatly appreciated.

Targeting RX 6000s series gpus for now as that would be what I can test on.

This would be the project repo it's forked from JLP's repo.

Just wondering because there is a good price on a RTX3060TI LHR and I was not sure it would slow down bitcrack or your Vbitcrack before I purchased it

I understand. You can purchase without fear of losing cracking speed or mining hashrate.

I had some non FE cards that were LHR, but once eth/gpu demand went down, they released drivers that took away the LHR or unblocked whatever they were blocking.

Do anyone happen to know if the LHR function in a RTX card will slow up bitcrack or vanity search or kangaroo

The LHR function has been removed since eth went to PoS. Upgrade the driver for full speed. I do not think it impacted kangaroo but it did impact BSGS cuda.

Hi Eter,
It is possible to automatically printed output number of decimal; which are reduced.

Yes, are you wanting to print all results to a .txt file?

Hi,
I wanted to automatically printed output number of decimal; which are reduced through bit range.
As like: https://github.com/iceland2k14/quick/blob/main/PubSub.py

Hi,
I have find range from script as below:

Priv: 0x3E70D3598B

As a result: divisor = 2**1 equivalent reduce is an 1 BIT range. So i wanted a output below example 0x02C9056EA5EBB46309024FF22C9668C2BEC887A0B3D48567CDB8D940F25B3C44D1 # -1072723486254

Please advice it is possible.

if you have privatekey and pubkey, and like div, and get print in file result pubkey and prvkey, its possible

Yes your results are correct. But this is possible because you know the initial private key otherwise you would have a problem your result would be wrong and your PubKey not found on the curve.
Try to perform the same operations with this pubkey 03770538afe9b82a6a4d6511ee28427f68ce2d4c4a2598fd5453232e304bedb9e0
and your result will be false very quickly where you will need +/-1 so 2^n for each operation then just for -10 bit 2^10 1024 operations X2 because +/- so 2048 (2048 pubkey of which only one will be on the curve with -10bit) 11 bit 4096 operations

This is impossible. you can print many keys, but the chance is small that it will be correct
