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

...The more times you try, the more likely it becomes to roll a 6.

Dice have no memory. The chance to roll a 6 is the same at every throw. So it is NOT more likely to throw a 6 the more times you try.

Guys, I've asked about probability and time previously: 1, 2 and got the answer that "Dice have no memory."

Okay, but I still could not understand what does it mean on practice. And to illustrate my frustration here is the animated image (actually it is html+css).

So, I could search forever for my 1 exact 9-prefixed address?

you should read on math subject of probability and chance
in short, probability is theoritical calculation on possible outcomes while chance is based on luck factor
in this vanitygen case, your luck depends on random seed producing targeted pattern
thus the chance is the same everytime because you starting with random seed every time

If you're running searches for months, you may want to make a longer list of words to search for. By making a list with prefixes you may find more cool addresses in the same amount of time.

and I agree with what he said, add a few more patterns to make it worthwhile
so with multiple pattern search on single run you can get your other desired patterns at once
for example: 1Thirdspace 1Th3rdspace 1Thirdsp4ce 1Th3rdsp4ce 13rdspace
if you just do single pattern, you might missed the chance hitting the other patterns
I wish I have the power to do that kind of pattern
but I was a bit lucky with 1Third address (on profile) using only cpu power
I got it in around 10-12 hour while it says 50% in 1.1d at the beginning

btw can someone response to my question a few post earlier
anyhow to modify the code to also work/search on compressed addresses

There has been someone who made this changes, and posted it in this thread. You'll have to search a bit, this thread has too many pages to quickly find back the link.
I never used it, as I have a hard time trusting new programs that create private keys. You could at least use it to compare the source.

[mahdaoui imad]

Find the version of solidcoin addresses and use this

[adaseb]

Pretty sure people will start modding this software to optimize for the RX GPUs to try and solve those BTCs in the old 32BTC brute force private key contest.

Its almost reached the point, where brute forcing the private keys for the 0.54BTC address will yield more profit than mining ETH or ZEC.

I tried to generate a custom bitcoin address by following this tutorial > https://99bitcoins.com/how-to-get-a-custom-bitcoin-address/

But I am getting the following error (marked in RED),


so is it a normal procedure of cmd or vanitygen or it is a problem?

Kind help will be appreciated in this regard.

[LoyceV]

But I am getting the following error (marked in RED),

You can manually set the number of threads to use:

Code:

-t <threads>  Set number of worker threads (Default: number of CPUs)

If you have 4 cores, use -t 4. Or -t 3 if your computer gets too slow.

I was wondering is it possible to use ASIC miners to mine custom address or does it only work with CPU?

[xhomerx10]

I was wondering is it possible to use ASIC miners to mine custom address or does it only work with CPU?

 No.  Address generation requires the use of RIPEMD-160 as well as SHA-256.

[adaseb]

Anyone here actually managed to get this to compile under Windows?

Seems every dependancy is outdatted and tons of warnings/errors.

[jankekek]

I was wondering what you guys thought of the idea of making a legitimate pool for vanity address mining. I was looking into the code for it, and it seems pretty workable.

There is one already, see: Vanity Pool - vanity address generator pool or Vanity Pool.

I have a my own generator (for Linux) that produces private key + address but not in base58 format.

I have another program in Python too that produces private key + address, I should search it. I don't remember performance, but surely much more than 1500keys/s. Are you interested?

This smells like jhdscript will soon open a new topic: 'Please Help! My Bitcoins have been stolen.'
My answer might be: 'Sorry for your loss'

Thanks for the trust.  

Anyway my program generates only "consecutive" keys. You provide:

1) the private key to start from
2) how many keys you want to compute

and it generates the corresponding addresses (hash of public keys, not base58 encoded). This is the output if you start from key = 1:

It is only up to the user to choose which keys to generate, not up to the program.

Besides I don't think that jhdscript needs to store a so huge amount of addresses to send some bitcoin there. Maybe it is only a statistical project.


@jhdscript

I made 2 tests (writing speed, Xeon CPU E3-1505 3 GHz + SSD, Ubuntu Mate 17.04)

1) supervanitygen:  about 220K keys / minute (8 threads,  that confirms that vanitygen-like program are not suited to your case)

2) my own generator: 75M keys / minute (-> 6,5GB file / minute) per 1 core. I got about 175 Mkeys / minute with 4 cores.

Unfortunately if I try to compile it for Windows the results I get are not correct anymore.  When I will have more time I will give it a look. For now I can't help you  (unless you decide to use Linux).
Honestly I can't figure out why you need to fill an hard disk so fast. It takes about 20 hours to fill 4TB.

Hi, how can I get your program to test?

[DarkStar_]

Is there anyone working on vanitygen fork to generate vanity bech32 addresses? Seems like it might be easier to get longer firstbits that make sense because it's more limited in characters.

[FreeMark2]

Anyone here actually managed to get this to compile under Windows?

Seems every dependancy is outdatted and tons of warnings/errors.

I've got it running on win 7 with a GTX 660ti running around 28 mil h/sec with oclvanitygen. Using the binaries linked in the original post it didn't take any tinkering.

Windows x86+x64 binaries here.  PGP signature here

Thanks for this really quick vanity address generator! I`ve read everything about changes, but i`d like to know what entropy sources it uses?

[Bell-Crypton]

Can anyone think of a clever way to distribute this: to let us search for the vanity phrases others want aswell as our own...

[btctousd81]

does the oclvanitygen only works with amd ati readon cards ? or with nvidia cards too ?

i tried

it ended without giving any error, and i got popup from windows7 ,

what should i do next ?

i know my gpu is not much powerfull, but still.

after more tries , i got it working.,

I am still continuing  that bash script for some of days and  hasn't found a simple ^1Abcd type of address right now.

Something must be wrong, I just found 1Abcd in a fraction of a second. Even a slow computer should be able to quickly find this.
