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

[TheRealSteve]

I know it will sound stupid but is there a way to get an address online like we used to from a trustworthy place? Something small like 1bitcoin.... so and so , is it possible to get it online like that?

'1bitcoin' isn't that small, but yes.. there were/are actually several services.

service	URL	distributed?	Split Key?	additional notes
Vanity Pool	http://vanitypool.appspot.com/	yes	yes	Easily the most popular.
Vanity Address Market Place	http://vanityamp.com/	yes	yes	Down for maintenance
Vanity Address Request	http://vanitypool.thruhere.net/	no	yes*	Shut down after allegedly being hacked, involving the split-key generation being offered as part of the service.
BitcoinVanity	https://bitcoinvanity.appspot.com/	no	yes*	Shut down after allegations of swiping users' funds, involving the split-key generation being offered as part of the service.
VircurVault	http://vircurvault.com/order/bitcoin/vanity/custom	no	yes
CoinBit	http://coinbit.tk/generate.php	no	no	down
gadman2	https://bitcointalk.org/index.php?topic=270180.0	no	yes	forum user service
devthedev	https://bitcointalk.org/index.php?topic=347591	no	yes	forum user service, currently not in operation?

Distributed = It's a service where people can use VanityMiner (part of the vanitygen package) to 'mine' for vanity addresses that other people want, and take a share in the reward that that person has paid the site.  Note that although these are commonly called pools, it's actually a distributed effort with winner-takes-it-all (minus the site's cut), so you don't get a payout based on your contribution even if you didn't find the vanity address.

Split Key = Requires or allows you to send in a Public Key of a Private/Public Key pair in order for the service to generate a vanity address without them being able to spend from that vanity address.  I cannot emphasize enough that you absolutely shouldn't use a service that doesn't offer this, and you shouldn't use a service's self-generated keys, as you can't easily be sure that they don't store the corresponding Private Key themselves (or have their site hacked to do so).

Also note that most of these will cost you some BTC in order to get the vanity address you want, and some may not even bother and simply say that your requested vanity would take too long.  The distributed ones are generally automated, so they don't much care what length you use, as long as you pay

nice post,i didnt know that there are so much sites offering this.
about the distributed thingy,did someone think about making a real "pool" for searching for addresses?
like in mining pools if someone finds the address all people wich took part in it get paid depending on their Mh/s
would this even be possible?

I'd say head on over to this thread, as that was discussed (somewhat) there:
Bitcoin Forum > Bitcoin > Development & Technical Discussion > Vanity Pool

Skip ahead to some talk about making it more like a regular pool:

Or:
https://bitcointalk.org/index.php?topic=84569.msg8388500#msg8388500

tl;dr: The service isn't really popular enough to warrant the additional work required to make such a scheme work - at least to the author

Please help me! After I changed the directory, compiling started but still showing error. My graphics card is crashing too.

I've been using oclvanityminer recently, and I've noticed that it uses 100% CPU and GPU. Shouldn't it use GPU only? Is there a way to disable CPU usage?

I've never had it use 100% CPU - it hovers around 30% - but that might depend on the hardware.  One thing you could check is what options it's using when compiling your OpenCL kernel.  Delete/rename the .oclbin file, and start up oclvanitygen(64) with the -v flag (verbose) to check.  Some output here:

Code:

Grid size: 4096x2048
Modular inverse: 2048 threads, 4096 ops each
Using OpenCL prefix matcher

If yours says it's using a CPU prefix matcher - that would probably be a good chunk of the CPU use.  Again though, mine's using the graphics card itself and still uses ~30% of the CPU.  Can't say I've looked at the code to see where that load's coming from - but at least there's nothing in terms of the command line flags to affect it one way or the other - and slowing the CPU portion down (through e.g. BES) does affect overall key generation rate.

Try making it work on one core only (RMB on the process and click on "Set affinity" if you're a Windows user, or use taskset if you're on a Debian-based system).

You could also try different driver and AMD SDK versions as not all are affected by the 100% CPU bug, but some combinations can make oclvanitygen stop working so do that only if you have time to play with this.

Had this exact problem too and looking for resolution

Please help me in Keyconv.c compiling too. It is terminating after showing "error: openssl/ec.h: No such file or directory. This is the line : #include <openssl/evp.h>"



Need help from anyone.

Can someone explain me why i have this:
 When i look without "-i" for, for example:    1LLLLL it gives me a dificulty of 259627881
When i look without "-i" , for,    1iiiii   it gives me a dificulty of 15318045009

Both of them dont have the mayus or minus etc. It's not a problem in the dificulty calculation because it takes less time for the "L" everytime i checked.

Why is this happening?
(It also happends for "1LLLLLL" six times gives me a really really low dificulty. The other leters takes me really long time)

Also:
"1iiiAL" without "-i" takes 15318045009
"1LLLLLL" without "-i" takes 15058417127

How is possible that even with more caracters i have less time of search? o.O

EDIT:
1iiiii dificulty 15318045009
199999 dificulty 259627881
Same amount of caracters

nice to know.thank u.i was always wondering if this site belongs to bitcointalk.org as part of a mirror/backup or something.didnt it visit,as i was scared.

Here's the original bit:

Caveat 2: Some prefixes are harder than others; https://bitcointalk.org/index.php?topic=301068.msg7478542#msg7478542

As an off-topic aside - bitcointa.lk doesn't really 'steal' content, it just mirrors it.. including (most) posts that get deleted.  That's why it's got any traction at all (well, some might prefer its UI as well).  Theymos doesn't seem to mind as long as the bots don't hammer this site too much (it would be trivial for Theymos to ban them and effectively shut bitcointa.lk down).  On a more positive note, this site should have new forum software at some point as well.

Please try to avoid the site when giving some answers. It's not a phishing site or something like that. It is like an alt-site. It is good for referring posts.

any luck on this working with Catalyst 14 and a 5xxx?

It also says Using OpenCL prefix matcher... Still consuming 100% CPU and GPU

You could also try different driver and AMD SDK versions as not all are affected by the 100% CPU bug, but some combinations can make oclvanitygen stop working so do that only if you have time to play with this.

It now consumes 50%... (100% of the resources that are given to the process)


Thanks for the tips. Maybe I'll update my drivers and see where it goes from there

[akuinginsukses]

I always getting this problem. Can you help me?

[Kangaderoo]

I saw your screenshot.
There is no configure for vanitygen, but you do have to run a

Code:

make vanitygen

command on a *ux system.
The assert displayed is related to a missing/not found OpenSSL library.

[Squeaker]

wouldn't mind being able to set how aggressive it works... (like the intensity setting on the miners)

I have a GPU with a dead fan on it I would like to have vanitygen run on, but no apparent way to fine tune how fast it sends work to the card, to keep the temp reasonable.
