I have read thru a lot of the pages and I have said it before and will say it again -  I am confused as to what the goal is here? Is it just to find the addresses? or is the actual attempt here to find a way to take btc from a wallet?

The goal depends on the one who use it. For example OP/the creator create this software to solve Bitcoin puzzle.

There's 2^256 combination of private key, so take/steal from an address is very unlikely goal unless people don't know this fact.

Not completely true.

It would be enough to try "only" 2^160 combinations (for example from key = 1 to key = 2^160) to be able to move the funds from all addresses (P2PKH utxo).  With about 2^135 combinations you should get access at one address with funds. (1 random)

and that is what concerns me - theft. while improbable I find it disturbing that it is the goal of a few on here - to steal.

True, but :
1. I was talking about private key combination
2. You still need to generate public key (whether it's compressed or not) from generated private key just to check if the public key has been generated previously
3. There are 4 address type (legacy, legacy P2SH, Bech32 and P2WSH Bech32) and software need to check each addresses contain bitcoin

and that is what concerns me - theft. while improbable I find it disturbing that it is the goal of a few on here - to steal.

There's bigger concern than brute-force, such as :
1. Bad PRNG/CSPRNG
2. Vulnerability within wallet software (such as private key or wallet password is kept on RAM)
3. Weak wallet encryption

Hello,
If you want to attack SecpK1 key you'd better try Pollard rho on "reused" addresses (you can get the public key coordinates). It will drastically improve your chance of finding the private key but will nevertheless remains very unlikely.
The technique is very well described here: https://arxiv.org/ftp/arxiv/papers/1607/1607.05901.pdf

I just compiled this tool and I reach ~15MKey/sec on my hardware using compressed key only (after playing a bit with options to find optimal setting).
I reach ~25MKey/sec with VanitySearch using compressed key.
First I think that trying to brute forcing bitcoin addresses is utopian and the performance seems far from optimal...

it would be great to also be able to use / associate the CPU to help the GPU a little as vanitysearch allows to allow an increase in speed

do you have an open source software ?

can you find the bounty transactions mabey faster with your strategy ?
[/quote]

Yes, sure I give out all the source to free to people in the third world, mostly India; The web-site is www.inflection.top, the github github.com/btc-room101, just tell me what you want,

I have 100's of tools I have written since 2012 when I started working on Bitcoin, most of the stuff is in python, and the gpu stuff of course is in C++;

I'm not inclined to put 100's of packages on github, so tell me what you want, I could make a list of what I have, best here is list what you want, and I'll tell you if  I have it, since I have done this crap for 6+ years ( hack bitcoin ), but I have been hacking crypto for 30+ years, so I have lots of code

I don't know what people want or need,

I think my site www.inflection.top discusses my areas of research, and the code, normally what I have done is from that site people ( usually students in 3rd world countrys ) send email and request code, I have found in the past that the 'guardians' of bitcointalk don't want anything real, they go out of their way to protect bitcoin, but as an intelligent person knows, knowing this stuff makes you strong, but instead the community prefers the continue the cannards and lies that has made them 'virtually rich', not unlike the little-prince ( a book ) where a man owned all the stars.

I would lke to see BITCOIN stronger, but the PTB want to keep it weak, just like FB,GOOG,TWITTER there is a concerted corporate effort to take away all notions of privacy and security. Here in BTC they tell us its secure, that its private, and anybody who steps forward with the truth is censored. This will be the downfall of BTC that it is over-lorded by imbeciles. In the meantime the RUSSIANS, CHINESE, and INDIANS will leave the west in the dust.
