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

[OgNasty]

Waited 8 days with 50%, now the window looks like this.

...

Is anyone able to explain what those % mean at all?
I can't understand what these % mean.
I understand that the higher % means higher chance to find the address, but do the % refer to a precise timeframe or?
And if it doesn't refer to a timeframe, what does it point to?

Is that 75% the chance to find the address in the next 8 days?
Or that after 8 days I will have 75% of chance to find the address in the following 8 days?

This has been explained time and time again...

The prob % is the odds that you would have found the address in the time you've been running the program.  In your scenario, it is estimated this job will take 32 days (at the rate shown in the screenshot).  It appears at this rate you've been running vanitygen for 16 days which is 53.2% of the expected time to find the address.  It goes a step further by telling you that in another 8 days, there will have been a 75% chance you would have found the address.

So, the first prob shows your current progress at finding the address (this is an estimate as it is random), and the second tells you more detailed stats of how much longer until you have a 50%, 75%, etc. chance at finding the address.

Thank you very much, sorry for repeating!
Should be put in the opening post, imo... that's why it has been answered over and over: because people can't find it. Nobody is going through 150 pages to find this answer.

It is on the first page...

"If I stop vanitygen when it reports 60% complete, how do I have it restart where it left off?

You don't need to.  The percentage displayed just shows how probable it is that a match would be found in the session so far.  If it finds your address with 5% on the display, you are extremely lucky.  If it finds your address with 92% on the display, you are unlucky.  If you stop vanitygen with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky."

That's pretty much self explanatory from there!

Fantastic.
In Windows, the CMD window closes immediately after finding the hash, so I lost the work of around 20 days.
Can anyone tell me how to let the window stick open when the search is over please?

Did you open it manually by starting cmd.exe, or by clicking a link? Test it by opening cmd.exe manually, then search for a quick prefix.

I made a .bat file that launches the .exe with all parameters.

I think that's where it fails. If you start the .bat file manually, it should be okay.

I'm not sure about the versions, but Command Prompt Here may help you.

Thank you for help.

For any other noob looking for help for a similar problem, just add a line to the .bat file with only pause written.
That will stop the window right there until you press a key.
You can copy and paste the text in the window by using the window's menu that is hidden behind the top left corner of the window itself.

And now let's start again and let's hope I will be a bit more lucky...

Does anyone know how to change the search option so that it searches for a pattern ANYWHERE in the address, not just the Prefix?

Currently, if you want an address with Bitcoin in the address, the only option we have is finding one that starts with 1Bitcoin********************

I was wondering if there is a simple option to change so we will search for the pattern anywhere in the address to find any combination of:

1**Bitcoin**********************************

1********************Bitcoin*****************

1************************************Bitcoin*

1*************************************Bitcoin

Thanks!

Does anyone know how to change the search option so that it searches for a pattern ANYWHERE in the address, not just the Prefix?

That's very easy:

Code:

Options:
-r            Use regular expression match instead of prefix
              (Feasibility of expression is not checked)

./vanitygen -r BTC
Pattern: BTC                                                                   
Address: 1DQCGcFRXJGRCFTjMar49ySJ5iE9hBTCzp
Privkey: 5Kk28XxGb5mpDpfEnmahtC8H5QjU8V8WyK6icZxRFiwJvzGZRP4

But: it searches 3 times slower than a normal search, and it only works on CPU, which is 25 times slower than using my GeForce. So it's fine for short prefixes like "BTC", it's a lot slower for the full "Bitcoin". Note that you don't need to do 1Bitcoin, unless you want the 1 in the middle of the Address too:
./vanitygen -r 1BTC
Pattern: 1BTC                                                                 
Address: 1JqA7etDfXTxW44d8q5q1BTC97qUS1FMYe
Privkey: 5K4ugngtPmYdiS4CXeDw4HMV9Au8cYyV5fkrQdf1w4eRgtB4PZy

Why would you want this? If you think it's faster to search anywhere, it's not. I can currently get 1Bitcoin in 23 hours (for 50% chance), "Bitcoin" anywhere could take months.

 Don't start from the bat file until you are in a command window.
Hold down the shift key and right click on the directory containing your bat file which will open a context window.  Left click  "open command window here" from that context menu.
Bob's your uncle.  That window will stay open until you close it.

Thank you, dude, I'll keep that in mind for the future.
For this task I solved by adding "pause" at the end of my .bat file, that works pretty fine!

Thanks, useful on a cpu.  I have read the discussion that the -r only works on cpu.

Using the oclvanitygen, I would like to search for suffix pattern matches,  that way if we would have a search pattern of "Bitcoin", it would only look for address matches 1xxxxxxxxxxxxxxxxxxxxxBitcon

looking thru some of the ocl code, it looks like there MIGHT be a way to change the search pattern from prefix only, to suffix only.  (maybe there is already OpenCL code/libraries built to do suffix pattern search, and all we would need to do is change a few lines in the oclvanitygen code) .  This is pure speculation from me.  IF someone that understands this well, is it possible and what would we need to change?

Does anyone have any ideas?  Thanks!

There are lots of distributed designs out there already, some open source but for CUDA, would need to convert CUDA language to OpenCL language. This would make it easier for those with large farms to utilize an address generator without it being a PITA to setup.Test CPU operation. This command line will generate a Bitcoin addresses beginning with 1ABCD in around a minute or less:
>vanitygen 1ABCD
Test GPU operation. This command line will generate a Bitcoin addresses beginning with 1ABCDE in around a minute, using the first OpenCL device in your system:
>oclvanitygen -d 0 1ABCDE

If you spend several hours getting oclvanitygen working with AMD Radeon 7xxx on 64-bit Linux - Ubuntu 12.04 and Ubuntu 14.04. In the end only the following is needed:
Ubuntu drivers
vanitygen patch
1 userspace library file from AMD APP SDK v2. I created a minimal instruction text file. Maybe this will save someone and some hours of searching the internet.
What do you should to do next is add a note to remove *.oclbin, since ppl with problems already have a compiled OpenCL binary and it wont be regenerated unless the file is missing.

Can I have a list of Vanitygen commands? After I made post #2126, I started my Vanitygen again. With normal commands. It is now at 5.9 percent.
The -i command means that it will run a case insensitive search. So if yo u want it to generate a 1JTK wallet with the "-i" command, it might then generate 1JtK instead. It basically just speeds up the generation time, but you're giving up case sensitivity.

Does anyone know how to search for Suffixes instead of Prefixes, using OCLvanitygen?

(I know we can use vanitygen -r Bitcoin$ )

[LoyceV]

Can I have a list of Vanitygen commands?

This gives the available commands:
./vanitygen -h

Code:

./vanitygen -h
Vanitygen 0.22 (OpenSSL 1.0.1f 6 Jan 2014)
Usage: ./vanitygen [-vqnrik1NT] [-t <threads>] [-f <filename>|-] [<pattern>...]
Generates a bitcoin receiving address matching <pattern>, and outputs the
address and associated private key.  The private key may be stored in a safe
location or imported into a bitcoin client to spend any balance received on
the address.
By default, <pattern> is interpreted as an exact prefix.

Options:
-v            Verbose output
-q            Quiet output
-n            Simulate
-r            Use regular expression match instead of prefix
              (Feasibility of expression is not checked)
-i            Case-insensitive prefix search
-k            Keep pattern and continue search after finding a match
-1            Stop after first match
-N            Generate namecoin address
-T            Generate bitcoin testnet address
-X <version>  Generate address with the given version
-F <format>   Generate address with the given format (pubkey or script)
-P <pubkey>   Specify base public key for piecewise key generation
-e            Encrypt private keys, prompt for password
-E <password> Encrypt private keys with <password> (UNSAFE)
-t <threads>  Set number of worker threads (Default: number of CPUs)
-f <file>     File containing list of patterns, one per line
              (Use "-" as the file name for stdin)
-o <file>     Write pattern matches to <file>
-s <file>     Seed random number generator from <file>

The -i command means that it will run a case insensitive search. So if yo u want it to generate a 1JTK wallet with the "-i" command, it might then generate 1JtK instead. It basically just speeds up the generation time, but you're giving up case sensitivity.

You could add -k to -i, so it keeps searching. That way you can be lucky to find the right case-sensitive prefix, and if you're not that lucky, at least you have a case insensitive prefix. Or more likely: a lot of them.

Does anyone know how to search for Suffixes instead of Prefixes, using OCLvanitygen?

You can't.
