My machine is getting ~1 million keys per second with oclVanityGen. Not sure if it's not using my GPU or not picking optimal parameters.
--
Yes, your program might be useful for creating a "beautiful" Bitcoin-addresses using VanityGen, but only for that.

It's not social engineering anything. It's simply a brute-force tool.

Please don't waste your time and resources to brute force a Bitcoin private key. Let's calculate how much time you need to crack one Bitcoin-address on your machine.

You said that your performance is 9 million BTC-addresses per second, i.e. approximately 223 BTC-addresses per second. Thus the brute forcing will take 2160-23 = 2137 seconds! I guess it is more than septillion (1024) years!

Note that this calculating is very approximate, because actually the private key length is 2256, but I think it is enough to stop making an attempts to crack Bitcoin-addresses.

The performance is good, but can likely be improved. On my hardware (GeForce GT 640) it gets 9.4 million keys per second compressed, 7.3 million uncompressed.

--

Try with other software to have a comparison.

I'm not touching LBC, as the client source code is not available.

Assuming that you are successful. What is the use of cracking keys when you are not scanning for balances. This is just another BIP39 social engineering clone tool. Yes BIP39 is a cool improvement but don't use it to fool the non-programmers.

--

I imagine people would check the balance for an address before trying to crack it. But like I said, it's main purpose is for the puzzle addresses, which have balances.

It's not social engineering anything. It's simply a brute-force tool.

Once you try to get people involved in a crusade like yours. It is social engineering. Your asking them to use your tool which is wasting computing resources. How can you brute force something that has combinations that almost rivals the number of atoms in our universe which is sha256.

This is good idea.
Do you think is it possible?
For this need many years.. or create worldwide GPU online pool

Good project idea.

How to deploy this to 100 CUDA cards?

thanks

It doesn't have distributed processing right now but it's on the to-do list.

For now you'll need to run it for each GPU on each machine. It shouldn't be too difficult if you have SSH access to your machines.

The main purpose of this tool is to contribute to the effort of solving the Bitcoin puzzle transactions: https://blockchain.info/tx/08389f34c98c606322740c0be6a7125d9860bb8d5cb182c02f98461e5fa6cd15

For all those (like me) wondering what the heck these puzzle transactions are, here is a link to an older tread trying to explain that:

Now at least you would have a clue what the OP is trying to achieve.
