Topic: Vanitygen: Vanity bitcoin address generator/miner [v0.22] - page 38. (Read 1152922 times)

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?!

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

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.

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 :/

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?

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!

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

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

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.

...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.

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.


I guess that makes sense. You get what you pay for. I wouldn't even know where to begin installing these things though so I'm looking for a relatively cheap computer that already has a decent (not the best) GPU inside. I don't think I want a desktop just because right now I almost exclusively do everything from my BlackBerry so wouldn't be able to deal with something that is stuck in my house!

I'm also assuming you can't just stick any old GPU in any old computer and it'll work for vanitygen too. So that's where I'm kind of trying to find something pre-made. I mean if it's as easy as opening up a laptop taking out a screw and putting a new piece in I'm good to go but past that I wouldn't want to mess it up and have it cost me $100+ to fix. Can a normal GPU even fit in a laptop? I really can't tell their physical size online. (Yes I know these are all noob questions don't worry )

I guess I'd have to up the budget to get a half decent GPU in a chromebook. I'm sure I could figure out how to get Ubuntu installed. That doesn't seem too too hard. It's the hardware that freaks me out haha!

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).

The best GPU you can use for vanitygen in my opinion is the R9 Nano.  There is no more efficient option.  Looking at a $250 setup probably isn't the best idea for long term use.  It may seem like a good idea, but low resale and high electricity use will end up sticking it to you in the end if you go with cheap hardware and run it for a good length of time.

I would skip the tablet for this. I can't help you with USD-prices, you may want to check something like pricewatch.com to find a good deal.

My laptop has a Nvidia GeForce 840M, it wasn't that expensive 2 years go, so you can probably find it even cheaper (or better) now.
I get about 7 Mkey/s, but it slows my system down a lot, so I run it when I'm not using my laptop. Desktops can get much higher rates.
What are you looking for? If it's only a few addresses you can ask someone to do it for you.

I'm so sick of generating vanity addresses on a CPU! I'm looking for a cheap computer, laptop or tablet (Hopefully around $250USD or less) that has a good enough GPU to generate some vanity addresses quicker than my old acer's CPU. It only gets 170k addresses per.. Second? Minute? Whatever the calculation is on vanitygen.

I've been looking at chromebooks but I just don't think the OS is adopted enough. I might get a chromebook and try to just install Ubuntu on it.

Does anyone have a recommendation of a GPU I should / shouldn't look for? I've heard that Intel GPUs don't work for vanitygen for one reason or another (it's honestly probably too complicated for me to understand) and all of my laptops over the years have had an Intel GPU.

The luck factor would need to be very high on the right moment with that rate to hit it earlier.

I guess you're trying to get 1omegaSt ? You'll need a bit more power for that.
It means there's 50% chance you hit in in 3.8 years.

 What prefix are you looking for?  4 years doesn't make sense for 1omega even with a only 289 kKeys/s...
I can do it in about 6 minutes with 25Mkeys/s.  If you'd like, I can create it for you but I need you to go to Bitaddress.org and create a private-public keypair and send me the public key so I can generate an encrypted version which only you can decrypt with your private key into the actual private key for your vanity address.  Here's a video that explains how to do it.
The first one is free

I see , I changed and It seems like It's creating/calculating or whatever It usually does.. does it mean It will finish in 4 years  

 The characters in your address must be valid Base 58 characters ie


 So capital o and zero are disallowed.
