Vanitygen: Vanity bitcoin address generator/miner [v0.22]

[OgNasty]

Anything specific I should be looking for in a GPU? Benchmark tests? The radeon R7 240 looks like a cheap option with good performance (unless I'm just way off).

A desktop GPU for sure.  If you run a GPU full speed in your laptop to generate vanity addresses, I would bet that you destroy your laptop before you ever find a 7 character vanity.  I wouldn't consider using anything less than a 7970 which you could get used for around $100.  Honestly though, don't generate vanity addresses on your laptop.  I think it is highly likely you will destroy your hardware, as laptops weren't made with the ventilation to be abused like that.

As you can see I really don't know too much about computers haha. If you say a tablet won't work then I'll just assume that's right. I'm just looking to have a chance at creating some very harder to find addresses over a long period of time (most likely) and not constantly run it. So maybe look for an 8 or 9 character address an hour a day or something.

...or you could hire someone with a decent GPU in a desktop system. 8 symbols (without exact case) is relativly quick to find (over night most likely) for me. Given the current electricity and bitcoin price I could e.g. do 1chrischr for 0.0037.

Can a normal GPU even fit in a laptop?

Nope. (If you ask questions like this, I recommend to buy a ready-made system.)

As a long-time laptop user, I have never had a broken fan. I always try to get laptops with a low-power CPU though. My GPU consumes more power now than the CPU.
As long as I keep it clear from dust, it runs at 60 ^oC.

Not for 250 USD, but its possible to fit desktop grade GPUs in a laptop. E.g. -> https://www.sagernotebook.com/Notebook-NP9873-S.html

At 12.13 LBs (5.5 kg for the rest of the world) that's more like a desktop with a battery.

You bring up some good points. I'll just look for a cheap computer for generating small addresses and if I need something bigger (6+ digits) I'll hire someone else to do it.

Ya OgNasty had brought up that idea too. Thanks for the offer shorena.

Lol either way that's 10x my budget so we'll go with no, I can't get a decent GPU in a laptop (for my price range). I'll see if I can find an ok or cheap GPU in a cheap computer so when I'm looking for a 5 digit address it doesn't take a few hours anymore haha. I guess that was my biggest need.

Thanks for the help everyone!

2 errors generated.

It's not driver-specific issue, seems to be difference in OpenCL implementations and their behavior on your hardware.

To fix it:
1. Open "calc_addrs.cl" with text editor.
2. Go to line 180 and change __constant bignum bn_zero; to __constant bignum bn_zero = { 0 };
3. Happily use your oclvanitygen

P.S. : forgot to mention, run with -S option enabled, otherwise it will throw out hashing mismatches instead of privkeys.

Thanks this actually works, i got same error while trying oclvanitygen with my r9 290. As you have mentioned, it doesn't work without -S parameter so i'm curious is there any further change to do, to make it work without safe mode parameter?

[Velkro]

Is there planned some optimizations to generation process? Is there any optimization possible?
I would like to generate quite long address but my gpu is too trashy to generate curently :/

[LoyceV]

^^ DO NOT USE THE WEBSITE ABOVE ^^

Velkro runs a scamsite that records private keys and steals your money. He also loves advertising his signature on subforums that don't show his trust rating under his name:

Never trust someone you wouldn't trust with cash with your private keys.

Even better: dont trust anyone with your private keys, use split key vanity.

Is there any way to generate a vanity address with oclvanitgen.exe, including a pubkey? There is no variable in the help definied. Would be very nice, due to security reasons.  Another thing: If I run without -S variable, I just get a CPU and GPU Hash. Is there any way to fix that and running without -S because it is much faster?!

This is the Lifeboat Foundation's updated application.  It will work on Windows with the current Radeon drivers if you trust them enough to run it.

Isn't there a way of doing it where you can get the address for them but not know the private key? I am sure there was with vanitygen but i havn't used it in a while. Someone with a farm of GPU rigs could do this for him if it is possible. Do not use that vanity creator site, i have heard of coins being stolen from those.. I would be willing to put a couple of GPUs onto it for a fee when I have moved if we can do it without me knowing the private key. I have a few GPUs at my command which I could use...

Split-key vanity generation is much slower and doesn't enable you to search for multiple addresses at once.  I can't imagine the way it is currently executed that it would be worth while for anyone to find lengthy vanity keys with that method.

Thank you man, I thought that is the same version like the original. I appreciate that and I have to say I was to lazy to search all the messages.

Split-key vanity generation is much slower

I've read this before, but it's not what I experience. I just tested it, for both vanitygen and oclvanitygen, and I see no difference in speed (key/s).

and doesn't enable you to search for multiple addresses at once.

It does, but they'll all work with the same public key. I use it to search for either one of several possible prefixes. For example: 1NAME 1Name 1name.
It's not as fun as just taking a list with 8000 long words as input though.

[DaveF]

I have been looking through the pages and pages of this post again.
I can't seem to find a list that I thought I remembered, is there a complete one that lists all the current cards and their speeds?
Or to make my life easier, if cost was no object what is the fastest card for generation?

Looking for 1 card not a rig.

Thanks,
Dave

I can't speak for your experience, only the facts.  Split key generation is slower because of the added process.  Your example of using the same public key for multiple split keys also restricts your search, meaning you cannot perform any other vanity searches not using that specific public key alongside it.  That makes split key generation slow and expensive to the point where I don't believe it makes sense for individuals to utilize it, or pooled miners to attempt profits mining vanity addresses.  It's a lose lose situation for everyone involved.

The fastest and most efficient card for use with vanitygen is hands down the R9 Nano.  Unless you can get a 480 to work, which I have yet to see outside of the claim on the wiki.

  Somebody created a Vanitygen page on the Bitcoin Wiki which contains a table with information that will help answer your question.   Most of the footnotes link back to threads (or posts I guess) that can be found here

What kind of speed does it do?
I searched the thread and see you commenting on it's efficiency but I am looking at speed.
Thanks,
