Question:

Is it possible to make search specific spaces in the priv-key? Like shown below in X:

00000000000000000000000000000XXXXXXXX000000000000000000000000000

Yes this is done by using -stride option

Yes, i got it but could not figure out how can i correctly mark the start-end points. Can you give me the stride setting for this example? This will help me.

Your sample is 64 length so i assumed it is hex privatekey format. On this basis the start, end and stride for the key search will be....

start = 0x00000000000000000000000000000000000
end = 0xFFFFFFFF000000000000000000000000000
stride = 0x1000000000000000000000000000

I think you will modify it accordingly to fill your 0 values in start and end..but no need to change anything in stride.

Thank you

I would suggest to stop using bitcrack until it is updated, if ever.

A 4090 using the vanitysearch with bitcrack option, gets 5000 MKey/s, and using KeyHuntCuda, a 4090 gets over 6000 MKey/s.

You are wasting MKey/s by still trying to use bitcrack, IMO.

Thank you, I wish I had known earlier

Hello, I also want to join the key finder (1000 BTC Bitcoin Challenge Transaction) but I don't know how to install BitCrack program (I have one rtx 2060 video card I want to try it), is it possible to have a detailed description or a video how to install this BitCrack program step by step and set it up correctly, I would like to try the selective method.

Hello,
there is a benchmark database of nvidia rtx 30s and 40s?

hi, I am also looking for such table, but no luck till now

My results with Ubuntu 22.04, nVidia 545.x.x drivers and CUDA v12.3 on i5 CPU, 96 GB DDR5 RAM, single RTX 4090 (water cooled, from MSI)

Software	t	b	p	result	Watts
cuBitCrack	256	256	512	~2975 MKey/s	466
cuBitCrack	256	256	1024	~3040 MKey/s	467
cuBitCrack	128	512	1024	~3080 MKey/s	467
cuBitCrack	256	256	2048	~3080 MKey/s	467
cuBitCrack	128	512	2048	~3165 MKey/s	464
cuBitCrack	128	256	4096	~3130 MKey/s	464
cuBitCrack	256	128	4096	~3090 MKey/s	464

I don't know if it can be better. I played with param values longer time, but many time I was stopped by "[Info] Error: out of memory" or "[Info] Error: too many resources requested for launch".

I would suggest to stop using bitcrack until it is updated, if ever.

A 4090 using the vanitysearch with bitcrack option, gets 5000 MKey/s, and using KeyHuntCuda, a 4090 gets over 6000 MKey/s.

You are wasting MKey/s by still trying to use bitcrack, IMO.

Thanks for reply, you are right. I am not using it anymore, just made test before and want to share some results.
I went to kangaroos/bsgs where is so much space for improvements and max 4090 utilization :-)

Can try different combinations multiple times, personal recommendation 256 512 1024 or 512 1024 2048？

I remember I saw somewhere the benchmark table with the speeds for BitCrack with different nvidia cards (2080,3080,4080, .... ti versions, Tesla, etc). Can you please share it or write the current benchmarks (actual in 2024 with the most common hardware).

https://bitcointalksearch.org/topic/m.55552855

Unrelated, but I am just wondering have you ever found any keys from all those sub-ranges you were searching in for on Bitcrack for a long time, or did you not find anything?

Hi guys,

I was reading this thread and found it interesting. Just a few questions get in my mind:
What if I find a zero-bit privkey address? How long would it take me to find a private key for this address, knowing only the address? Is it a million years, assuming that I don't have a public key?

Can you show us what you mean by zero bit private key? If it has "zero" bits then how can you derive an address from it? But there is a solution for you, it's not related to zero or 256, you can find 2^96 different private keys for every single address out there, under one condition, you'd have to brute force 2^80 keys to find one collision.(in theory)
Without public key, only having the address and knowing the exact range, you can go ahead and try puzzle #66, even if you halve the range, you'd still need to grind 2^65 keys.😉

Sorry for confusion. I just try to understand the whole thing, that is why i am asking. For instance a wallet 1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH had a very simple private key of 0x0000000000000000000000000000000000000000000000000000000000000001? This means it is easy to crack it as the only thing is needed is checksum?
So if i would ever find an address with a privkey of 0x0000000000000000000000000000000000000000000000000000000000000001 but no public key - is it something i would have to run 2^65 keys to open it?

it will take you 1.42 million years to find the solution to your zero-bit question
