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

[God]

So, I use importprivkey to get the private key into bitcoind. Will it then automatically detect payments to my vanity address? No need to get bitcoind to recognize the vanity address?

Pretty much, yeah.

Compressed keys has been discussed before, but I wonder if anyone considered it for potential speedup? So every time a new EC point is calculated, you produce SHA256+RIPEMD for both the uncompressed coordinates (04 "x" "y") and the compressed ones (with leading byte 02 or 03), this basically doubles the chances to match the required prefix without adding too much overhead (just an extra hash).

To take this further, one might as well also hash the inverse point on the curve (x, -y). As long as one can hash faster than EC_POINT_add I think it is worth it?

Hi guys, I think I need some advice to compile and build the vanitygen against openssl 1.0+ on osx Mavericks 10.9.1

I 'make' it after upgrade openssl but it says:

Code:

WARNING: Built with OpenSSL 0.9.8y 5 Feb 2013
WARNING: Use OpenSSL 1.0.0d+ for best performance

if I then check the openssl version i got:

Code:

OpenSSL 1.0.1f 6 Jan 2014

so i symlinked the new openssl to the include and retried the 'make'
this is the output:

Code:

cc vanitygen.o pattern.o util.o -o vanitygen -ggdb -O3 -Wall -I/tmp/openssl-1.0.0j/include -L/tmp/openssl-1.0.0j -lpcre -lcrypto -lm -lpthread
ld: warning: directory not found for option '-L/tmp/openssl-1.0.0j'
undef: _PKCS5_PBKDF2_HMAC
Undefined symbols for architecture x86_64:
  "_PKCS5_PBKDF2_HMAC", referenced from:
      _vg_output_match_console in lto.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [vanitygen] Error 1

I think i have to modify the Makefile to adapt it to 10.9.1 but i'm not so skilled to do it by myself,

can anyone help?

Thanks

This is great i used it to make addy from my sig .

Heheh... My username is just perfect. I even got 1Micro... addy in just few hours
I also sold some addyes but urs username is to long even for me

I used a work PC @ 25 Mkey/s for over 3 months to try and find 1tri11ium with case sensitivity off and no luck.

I just checked that would take me forever . U would need to pay for it at least 0.1 btc. Did u tried some pool ?

Does anyone have any good tips or suggestions on how to tweak the oclvanitygen settings so that my computer will remain responsive while running the program?  I'd like to dial it in to where I can get good speeds while still being able to do other activities while it is running. Thanks.

Edit: Played around and did some tweaking.

No tweaks, Default-
Grid size: 3584x2048
Modular inverse: 7168 threads, 1024 ops each
Keyrate: 22.00 Mkey/s
Observations:  Very laggy, lots of input delay, and slow responsiveness

1st Tweak, More Speed-
Grid size: 2048x2048
Modular inverse: 4096 threads, 1024 ops each
Keyrate: 22.50 Mkey/s
Observations:  Slight lag, small input delay, and best of all higher keyrate, yay!

2nd Tweak More Responsiveness-
Grid size: 1024x1024
Modular inverse: 4096 threads, 256 ops each
Keyrate: 21.20 Mkey/s
Observations: Very little lag/input delays (almost none), and only a small decrease in keyrate, success!

Note: I did try a grid size of 2048x1024 as well as 1024x2048.  They were both about 22 Mkey/s and both had about the same responsiveness which was between that of the 1st and 2nd tweak as you could have guessed.  So it doesn't seem to matter if you use square grids, it is only the size that matters in my experience.

System info for anyone wondering:
I5-3570k at 4.4 GHz
GTX 660TI by Asus
Windows 8.0 64 bit
4x4GB of 1600 DDR3 ram

Anyhow I think these tweaks were quite successful and I'm very happy with them.  If anyone still has any tips or suggestions maybe I can improve them some more.  Thanks.

I have a problem: when i start oclvanitygen with 1something, unless to generate public and private key, vg generate a useless cpu and gpu hash...

How i can resolve?

Can you give the string you're using, and the output from the window?

Code:

oclvanitygen -p 1 -d 0 1something

And output like this:

Code:

Difficulty: 264104224
[22.86 Mkey/s][total 455081984][Prob 82.1%][90% in 6.7s]                       
Match idx: 0
CPU hash: 71682fec9bcafa7b1291c2cc09954692b716ca3e
GPU hash: 099bccd501a398a56eff31b40b924d8d9b132b72
Found delta: 4131272 Start delta: 1

I've started to experience this as well, I have concluded this problem is related to newer drivers (eg 13.xx). I had this card working great with v 12.8 Radeon drivers, as have many others.

I'm experiencing this as well.

same problem - how do i fix this?

oh one other Q, is it possible to use the generator for altcoin addresses? I assume yes, but in that case I assume one has to modify the source code?

No you don't need to.
This subject has been discussed in this topic. U have to use option "X" with the code of the coin.

Something like this: vanitygen -X 48 -o addys.txt LTCmis
The same for OCLVanitygen...... Be aware to state as first and second letter according with coin specs

For LTC: 48
FTC: 14
NVC: 8
ANC: 23
PTC: 47
CNC: 28
DGC:30
NMC: 52
PPC:55
YAC: 77
BQC: 85
IXC: 138
DOGE: 30

Hi everyone, I'm having tons of fun with this, but need some help. With oclvanitygen, i made a .bat and added pause so I can actually read the thing for a moment.

I see it's recognizing my 3 GPUs and CPU just fine okay good. I have a AMD FX-9370 8-core 4.8 Ghz cpu, an R9 280x (another coming tomorrow yay) and two Asus 7870's. So I have plenty of power. In fact my cpu is solving tons of fun addresses with vanitygen64 so I have that all figured out.

What do I add to my .bat file to get it to "work" on say GPU 0, my powerful one? I can't seem to get oclvanitygen mining on anything. And the OP is super vague and missing all this info on what to tell oclvanitygen.

Thanks!

Try different devstrings. The -D option lets you select which computing device to run on.

okay cool so something like "oclvanitygen.exe -d 0 111" oh wait I already tried that, -d 0

[Anthropolis]

Okay I think I have it almost figured out now :facepalm: You have to specify -D 0:0 for example. Found the list of commands just by running a .bat with oclvanityge.exe pause, then it lists available commands for the running .bat
