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

[rico666]

I need someone who can make custom changes to vanitygen and oclvanitygen.

I would like to use them in the Collision Finders pool project instead of the address generator that is in use now (some compiled Go program).

Objectives:

1)

I'd need to mimic the output of the "generate" executable we have now (an offline version of directory.io), where "generate X" will spill out 2²⁰ addresses both in uncompressed and compressed form like that:

Code:

> generate 0

1EHNa6Q4Jz2uvNExL497mE43ikXhwF6kZm 1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH
1LagHJk2FyCV2VzrNHVqg3gYG4TSYwDV4m 1cMh228HTCiwS8ZsaakH8A8wze1JR5ZsP
1NZUP3JAc9JkmbvmoTv7nVgZGtyJjirKV1 1CUNEBjYrCn2y1SdiUMohaKUi4wpP326Lb
1MnyqgrXCmcWJHBYEsAWf7oMyqJAS81eC 1JtK9CQw1syfWj1WtFMWomrYdV3W2tWBF9
1E1NUNmYw1G5c3FKNPd435QmDvuNG3auYk 17Vu7st1U1KwymUKU4jJheHHGRVNqrcfLD
1UCZSVufT1PNimutbPdJUiEyCYSiZAD6n 1Cf2hs39Woi61YNkYGUAcohL2K2q4pawBq
1BYbgHpSKQCtMrQfwN6b6n5S718EJkEJ41 19ZewH8Kk1PDbSNdJ97FP4EiCjTRaZMZQA
...

If the vanitygen/oclvanitygen is "too fast"  for a tiny 2²⁰ block, I can live with 2²⁴ or similar.
You can find the currently used executable at http://lbc.cryptoguru.org:5000/downloads/LBC-client/generate for comparison.


2)

I need to know if vanitygen is using a slower/faster SHA256 code than http://www.intel.com/content/www/us/en/intelligent-systems/intel-technology/sha-256-implementations-paper.html and in case it uses a slower one, integrate use of the intel-specific implementations.


Of course, I'm willing to pay for both objectives - 1) is prerequisite for 2) - with my precious Bitcoins. PM me, if you are capable of and interested in the job.

I've also got a small improvement to the program: One of the miners, CudaMiner I think it is, has a function to start and stop at a set time.

eg someone living in a warmer climate where their cards would overheat during the day, Vanity Gen could start at (in this example) Six PM and pause at Six AM the next morning.  That way a user wouldn't have to manually stop/start the program and they would be able to keep going at the point they left off without the "luck" timing out and restarting.

Or a work PC at 5pm Friday and search all week-end then pause at 7AM Monday morning.

If you follow me?

I guess you could use the cron daemon and friends to put the task into the background (so that it will be halted) and bring it back to life when needed

I'd really need to be walked through what you just said, but thanks for the suggestion never the less.  (Would this happen automatically?)

Just thought of another one - updating the search list when the work.txt file has been updated, the program occasionally re-polls the work.txt file and adds new items without the program restarting.  (Is this possible?)

It all depends upon what system you use (I don't know if it is possible to suspend a process in Windows)

cron (not to be confused with tron), bg, fg, and kill

I have been reading bits and pieces of this thread but not all so forgive me if I ask a question asked before but.... is there a way to run oclvanitygen across multiple cards, like as an ETH miner would / old setup?

C:\>oclvanitygen.exe -D 0:0 -D 0:1 -D 0:2 -D 0:3 -D 0:4 -D 0:5 1prefix

That's for 6 cards

Sorry for my noobness like me... how does one import keys? And is there a way to make the search caps-insensitive? Thank you

 open the console and enter importprivkey privatekey label

be prepared to wait while it scans the blockchain for transactions (could take a while).  There is a noscan option for that command but it's inadviseable.  I think you would type false after your label.

 use the -i switch in vanitygen or oclvanitygen for case insensitive searches.

I didn't know the noscan-option exists. "Noscan" would be okay if you import the address before depositing to the address, or if you want to import several addresses and scan them all at once afterwards (rescan 86 GB can take longer than creating the address).

It would be great if this also works with a "pruned" Blockchain, so you can still import vanity addresses without downloading the entire blockchain again.

Any idea what the exact command would be? I've tried several options (noscan, norescan, rescan=0, rescan=false), but it instantly says "Rescan is disabled in pruned mode". I don't want to rescan, I just want to import the address.
Someone posted the same idea on Github 2 weeks ago. I guess it's not possible yet.

In a way importing vanity addresses is the same as importing from cold storage. It has been tested on Reddit. Conclusion: It should be possible to get the balance without downloading the full blockchain again, but it's not (yet?) implemented.

Edit: I'm confused: somehow it did add a watch only address, but it says it requires a rescan to show the balance. I haven't been able to import the private key though.
Now I get what you meant! I did "importaddress 1something rescan false". It imports the address without rescan, and "rescan" is the label of the address. So I should import it useing "importaddress 1something Something false" to give it a more useful label.

 You got it!  It takes no time at all this way but if you had coins in there, they might not show up until the next rescan.

I lost my wallet dat but I still remember my bitcoin Address, can I recover it using vanity?

Help please.

If you don't have the private key of your wallet written somewhere, I guess you are lost and can kiss good-bye to your coins (your Bitcoin address itself is a hash of the public key)

 Not in a million years with a million GPUs.  Sorry for your loss.

What was your Wallet Address?

Can GPU's only be used for the oclvanitygen?  I can't figure out how to turn my GPU's on for vanitygen64.exe?

Vanitygen64 is for CPU, oclvanitygen is for GPU (if I understand correctly  but I only have an Intel GPU which can't be used for on reason or another so I haven't personally tested it).

You can't. If that would be possible, anybody could "recover" any Bitcoin address.
You may be able to recover your wallet.dat file, depending on how you lost it and how much you're willing to try (or pay).

So when I find an address and it shows the public key and private key in the command prompt, is there a way I can copy and paste the two keys into a notepad file so I dont have to write each character out?
