 Seems like you need a specialized computer program to run through the possibilities for you but not Vanitygen.




Thanks for the info. Yes I understand I need some special software to do so, but there was a user "bdb" who modified vanitygen to make it go sequential and managed to get it to work.

I then patched the VanityGen code to solve the same problem.
This is only a very small mod.
- set the initial private key = 1, rather than random
- change the pattern matching [you could probably even use the existing one; but there is no need to convert to b58]


If its an easy modification then I would try it out. But I rather not start coding from the beginning. Afterall the reward is very small for so much work.

This option is used to tell VanityGen to use a seed from the file you specify instead of its default seed ( which is from OpenSSL or /dev/urandom on Linux ).

I don't recommend using this option as the default seed should be secure and random enough and if you use this option to use a seed from a static file, someone else with the same seed could generate the private keys for the addresses you create. This feature is likely designed for if you have a hardware RNG device that you wish to use as a seed which I doubt many people have.

Option -s uses a random file as extra input. If you search for the same prefix twice, you don't get the same result. You can easily test this for yourself, I just did, and got 4 different addys.

Option -s uses a random file as extra input. If you search for the same prefix twice, you don't get the same result.

Are you sure its extra input and not replacing the RNG data that is normally used?

samr7 indicated the following in the initial post:
Quote
Nonetheless, if you feel the default RNG is unable to provide numbers that are sufficiently difficult to guess, vanitygen can be directed to seed the RNG from an external file using the -s option

That line seems to indicate its seeding entirely from the external file and not just using it as additional data.

Yes it definitely adds to the random seed and definitely doesn't set it to some initial value. I've been searching for an easy way to mod it so it would search sequentially so I could get the 51st bit in that 32 BTC challenge thread.



By the way I launched a Vanity Generation Service at https://bitcointalk.org/index.php?topic=1748422.0
Basically I offer free easy vanity generation and charge for harder to find vanities. So if you have a very slow CPU and want a basic vanity I can find it for you instead.

IF this post is considered spam, I apologize and will remove it.

Just wondering if there is anyway to disable the CPU checking when using GPUs on oclvanitygen.

It seems that any GPUs connected to a 1x PCIe slot run at 50% the speed compared to the main GPU thats connected to the 16x PCIe slot.

Seems like there is a bandwidth bottleneck creating the slowdown.

So I recently spend three hours or so generating a new vanitygen address on my Notebook that run on AMD graphic processing unit. Before it reaches 50% it show something like

Code:
Match idx: 0
CPU hash: [removed]
GPU hash: [removed]
Found delta: [removed] Start delta: [removed]

I Googled for this 'error' and it seem that this only happen when the GPU code do not match with the CPU code, hence not showing us the private key. The vanity address I was trying to generate was 1nTech.

I couldn't find a fix for this problem online - other than using my CPU to search. I followed an advice and generate short vanity address to see if this problem will occur or not, it does not occur and I manage to get the private key - for example 1111.

Anyone have any fix for this?

(I tried upgrading my AMD graphic processing unit but somehow my Windows have 'blinking' issue so I revert the upgrade.)

 A while ago, OGNasty told us about https://lifeboat.com/oclvanitygen which will run with the latest radeon drivers.
Perhaps you could try that version instead.

So, does anyone else have/had an issue where olcvanitygen never finds a matching key, and just continues searching regardless of how easy the request is?

Yes, in regex mode with an invalid "prefix", which is to be expected.
