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

[SodaWarz]

Do any of you guys have a link to the version of Vanitygen that ouputs in .csv format. (address,key)?

I downloaded it over 6 months ago from somewhere and my hard drive died. i didnt back up the .csv Vanity as i figured i could just re DL it, but now i cannot seem to find the link...

Its good for all quote this thread

Great software , all hail to opensourcing

I tried to search for a specific wallet address just for fun, and it the program crashed. It was not until i removed 6 characters from the end of the public address did it do its thing. I know the chances of finding 1 specific public address is like winning the lottery 500 times in a row but i would like to be able to. Is my hardware the problem or the code?

In order to speed up code execution the final step, adding the checksum to the result is skipped.
This checksum is 32 bit, equivalent to 6-7 characters in base58.

You may want to run with the regular expression option, in this mode the checksum part is added.
Code execution will slow down considerable though.

My code actually reports the prefix being to too long when using a complete address in stead of crashing,
there are many versions out there :-).

Wow, I found this too late. It is truely good for those who want to have a personalized address. Cheers!

[Prompyboo]

yup too late

I hope someone can help me get this running properly. I have searched for answers to no avail.

[snazz]

Never mind, using older drivers fixed it.

Hi, I was wondering if someone could help me.

Is there a parameter for vanitygen to stop it from outputting stuff to the console?
I want it to run on the background of my ubuntu server, so I use './vanitygen -i 1jerodev &', but it keeps sending things to the console and it is verry anoying.

Thanks for helping,
Jerodev.

i have the same problem, does anyone can use it on background?? :S

Hi,

Trying to do some mining with vanity gen on vanity pool, but i am having a hard time with it.

I am on windows 8.1, got a Radeon R9 270x card and Xeon E3 cpu, could someone please post an example of the bat file to start the miner?

Also tried finding it in the thread, but after browsing the pages could not find the info.

thanks in advance!

You must have missed the first post:

Code:

$ ./oclvanityminer -u https://vanitypool.appspot.com/ -a 1samr7UZxtC6MEAFHqr1h3Kq453xJJbe4

So on windows, your .bat file would look something like:

Code:

oclvanityminer64.exe -u https://vanitypool.appspot.com -a 1youraddress

Or

Code:

start "Vanity Miner: Pool" /low oclvanityminer64.exe -u https://vanitypool.appspot.com -a 1youraddress

To give it a nice window caption and slightly deprioritize the process.

If it's not working, I recommend that you try to get oclvanitygen working first - in case there's any issues using it with your card or having to select the right OpenCL platform.

What's the maximum prefix you can generate with a top end computer?

[crazytasty]

What's the maximum prefix you can generate with a top end computer?

No more than 8 characters.

It's a bit more nuanced than that.  You can certainly generate longer ones:

Code:

vanitygen 1abcdefghijkLmnopqrstuvwxyz
Difficulty: 164888818503458230623158005923420463190199545920
[830.19 Kkey/s][total 6228992][Prob 0.0%][50% in 4.365470e+033y]

Except that it would take, on average, a very very very very very long time.

But 9 characters is perfectly doable - this is on a not-all-that-beefy laptop:

Code:

oclvanitygen64 -p 1 1abcdefgh
Difficulty: 2988734397852220
[5.39 Mkey/s][total 75497472][Prob 0.0%][50% in 12.2y]

I still wouldn't want to wait 12 years, but if you do.. why not.

Moreover, it's an 'on average'.  It's possible you could get a hit a split second after you call the command, and it's also possible it would take centuries to get a hit.

Note that this is if you absolutely must generate one for whatever reason.  If you're talking about mining, then perhaps a 'maximum prefix' would be contingent upon profitability, in which case you'd have to consider whether the bounty equals or exceeds your expenses for vanity mining - and that is a calculation that is, again, subject to that 'on average' caveat.

The only theoretical limit is, I think, 30 (including the leading '1'), as that's when you exhaust the number of characters available in a bitcoin address to begin with.

I've made a vanity pool recently http://multicoinpool.org/index.php?page=vanity

I can put up the fixed vanitygen binaries if desired.

Thanks! didn't miss it just didn't understand right.

i had to open a command prompt and enter the 2nd command you post but it wouldn't start untill i added "-D 0:0" which is my GPU, so in my case the command line is:

Code:

oclvanityminer64.exe -D 0:0 -u https://vanitypool.appspot.com -a 1youraddress

Now i am mining with ~20Mkey for "1Smoothie" with 50% prob in 3.3y. Any way i can further optimize it?

Thanks again

You can try playing with some of the finer parameters, but it's probably not going to get much better; even if you speed it up 2x it'll still be well over 18 months (average)

I raised it to 22Mkey by overclocking the card. got no idea which params to try, but it's late now for me. maybe i'll try tomorrow.

If i get lucky and solve it where is the result saved and how can i redeem the reward?

Also, can i choose which work to do, instead of being assigned by the pool?

Basically the -s, -t, -g, -b parameters, there's really not much else to tweak.  A better option would be to see if you can optimize the actual code further / specifically for your card.
Also use the "-F compressed" option, that should boost performance a bit further.
And if you're not already using the lifeboat version, see if that gives you a performance boost as well - though read its thread for details and possible concerns.

If you're using the oclvanityminer, then the result is automatically submitted and the pool should pay out to the address specified.

Also, can i choose which work to do, instead of being assigned by the pool?

Technically it's not assigned by the pool - the utility downloads the complete list and does a calculation of which is the most profitable given reward vs difficulty (the 'lavishness') to decide on the vanity to mine for.
There's an alternative code base that has some additional control: https://github.com/WyseNynja/vanitygen/commit/fb37cfbcfaf8a6922cc2b872cb19a11fdc252c92

But if you want further control - say, only mine if a given address should be generated within a week (on average!) - you'd have to set something up manually or mess with the source code yourself.

Also just to note (though I believe you understand this, mostly repeating it here for the new eyeballs on this thread) - keep in mind that it isn't really a 'pool' so much as a distributed task.  If you don't find a requested vanity address, you get nothing, even if your machine's been powering away at it 24/7.
