It's a shame that the demand for results from this service is so low. That means its almost entirely unprofitable for anyone with GPU to try and solve for these patterns. In fact, you are just throwing away money.

Currently the best work is: "Searching for pattern: "1Thanks1" Reward: 0.010400 Value: 0.000001 BTC/MkeyHr"

$842 (bitcoinaverage price) * 0.010400 = $8.75 USD

Time to reach 50% probability on a overclocked Radeon 6870: 17.2 days

Power consumption: measured 120w AC:

0.12 kW * 0.30 $/kWh * 24 hours * 17.2 days = $14.86

Or, I could mine dogecoin (presently #1 scrypt coin) for 17.2 days and earn a profit (after electricity taken into account) of $50.40... and get paid with 100% assurance.

I agree that it's a shame the vanity pool allows such low reward values.

It would also seem useless to mine just vanity addresses for rewards on paid power or with a full GPU.  For those with cheap power though it seems like a huge waste IE throwing away money to take a single or dual core CPU and a powerfull GPU and just mine scrypt coins. There are some cycles left over on the GPU and the CPU's are generally just about idle.

the problem with that vanity mining pool is it only mines the single most profitable vanity. The vanity miner program has the capability of mining multiple different prefixes all at the same time, which I've done in the past. After all, it's just generating random keys in an attempt to get a matching result. No reason it can't compare that result to more than one desired prefix.

Agreed, I used to search for 30+ prefixes at a time

hi,

i've got these errors when compiling :

Code:

winglue.h :

Code:
#if !defined (__VG_WINGLUE_H__)
#define __VG_WINGLUE_H__

#include <windows.h>
#include <tchar.h>
#include <time.h>

strtok_r(char *strToken, const char *strDelimit, char **context) {
return strtok_s(strToken, strDelimit, context);
}

#endif /* !defined (__VG_WINGLUE_H__) */

Someone knows how can I fix it ?

When I launch the file, it launches the command prompt but then immediately shuts it down again. What can I do to access it?

if you are using windows, shift+right click the folder containing vanitygen executables. when the window opens already at that directory path, you can then paste (via the square top left of window) a string like:

Code:
oclvanitygen -D 0:0 -i -k -o found.txt 1tri11ium

Also open a command prompt instead of double clicking the exe file before following the above directions. Smiley

If you shift+right click a windows folder and select "Open command prompt here" it sets the current directory in the cmd window that opens automatically to that folder. You do not need to click any exe files etc.

General formulas for expected performance on GPUs

NVIDIA GeForce 96xx, 98xx, GT 1xx, GT 2xx, GTX 2xx (G90/GT200):
Key/s = (CUDA Cores) x (Shader MHz) x 17

AMD Radeon 58xx, 59xx, 67xx, 68xx (VLIW5):
Key/s = (Stream Processors) x (Core MHz) x 20.1

AMD Radeon 69xx (VLIW4):
Key/s = (Stream Processors) x (Core MHz) x 13.6

AMD GCN, NVIDIA Fermi/Kepler: Please contribute some numbers!
I have an NVIDIA GeForce GTX 560. With 336 CUDA Cores and 1780 MHz Shader (890 MHz Core, 1000 MHz Memory), I get ~14.1 Mkey/s. This suggests a ratio of 23.6 for this card. That is, Key/s = (CUDA Cores) x (Shader MHz) x 23.6

Hi, I carefully studied a regex to search for, but it seems vanitygen can't accept the character ^ in the regex in order to force the following group of characters to be the beginning of the address.

vanitygen simply ignore the character ^, while it correctly take as input the character $ to force the group to be at the end of the line. each address it returns, it writes the pattern searched without the ^ character.

basically I'd want to search for an address with a custom prefix and suffix. any help is appreciated.

edit: ok found the solution, had to enclose the searched pattern between ""

I've updated https://github.com/WyseNynja/vanitygen with 2 bug fixes reported on GitHub.

If you already have vanitygen installed from my OSX homebrew tap:

Code:
brew update
brew prune
brew upgrade vanitygen

If you don't:

Code:
brew tap WyseNynja/bitcoin
brew prune
brew install vanitygen

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

jaap
