I prefer Zakir over Muhammed when mentioning me!

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.

Please do not link to scumbag site that stole their content from here.

Here's the original bit:
Caveat 2: Some prefixes are harder than others; https://bitcointalksearch.org/topic/m.7478542



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.

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

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?

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.

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.

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:
https://bitcointalk.org/index.php?topic=84569.msg5211968;topicseen#msg5211968

Or:
https://bitcointalksearch.org/topic/m.8388500

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 Smiley

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.
serviceURLdistributed?Split Key?additional notes
Vanity Poolhttp://vanitypool.appspot.com/yesyesEasily the most popular.
Vanity Address Market Placehttp://vanityamp.com/yesyesDown for maintenance
Vanity Address Requesthttp://vanitypool.thruhere.net/noyes*Shut down after allegedly being hacked, involving the split-key generation being offered as part of the service.
BitcoinVanityhttps://bitcoinvanity.appspot.com/noyes*Shut down after allegations of swiping users' funds, involving the split-key generation being offered as part of the service.

devthedevhttps://bitcointalksearch.org/topic/bitcoin-vanity-addresses-100-vanities-generated-347591noyesforum 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 Smiley

Use split key, no trust involved. See my signature.

do u mean u want someone to "hire" so he makes u the 1bitcoin address? if so just go to this website https://vanitypool.appspot.com/

it uses ur public key to generate ur new address.but keep in mind 1bitcoin or even longer will takes some time to finish.

but I however to the end understood how to use pubkey.
here line with the key over brought by you.

You don't actually specify a public key, it's just the word "pubkey":
Code:
vanitygen64.exe  -F pubkey 1abc

If you are trying to generate a vanity address for somebody else, and they gave you a public key to use for a 'split key' generation (the way the vanity pool websites work, or at least should work), then you actually need to use the -P parameter:

Code:
vanitygen64.exe -P 04C57E907AEC9BA14D377EA1627672197A87D38A0BB12390B1504FF9A6A941772D052906B5A5AFB908E096C1C884C0E14096BB47EAC617C99DEDADBC4AE5241F7 1abc
Difficulty: 4553521

PrivkeyPart: 5JnhiD6kAxkQiWBmJqupkS5qR2PFUwCQWq1DAyqcWj2wkU1HYqz
They would then combine the PrivkeyPart with their PrivkeyPart to get the Private key for the generated vanity address.

Hi all!

vanitygen parameter "-F" in what format pubkey need?

"pubkey" is already the default.  The -F parameter would be used as following:
.exe -F pubkey 1...
.exe -F compressed 1...
.exe -F script 3...

Each bitcoin address is the result of an encoding of a hash the public key.  That public key can be expressed in two ways, uncompressed (equivalent to X and Y coordinates) and compressed (equivalent to X coordinate and a sign, from which the Y coordinate can be derived).
Say you generate '1abc' using both (don't actually use these keys/addresses!):
Uncompressed (default):
Code:
vanitygen.exe -F pubkey 1abc
Difficulty: 4553521
Pattern: 1abc
Address: 1abcCjhme96hnPDe3pDc3Ch1EnEj5Rjv7
Privkey: 5KG6rYdSopgYo1rejJAdPfbS6RgqhtAecg7EA19mJi9P9s2Ftru
The private key for an uncompressed form always starts with a 5.

Code:
vanitygen.exe -F compressed 1abc
Difficulty: 4553521
Pattern: 1abc
Address: 1abcRZRi2Gh4tZHJNbAyVyjSRx8uB67jk
Privkey: L2i2dzuR7CtDTkXQeh2m9jKiBtuxFNTTCHobBb3bySaHhxDFf6WK
The private key for a compressed form starts with a K or an L.

This is generally how wallet clients etc. recognize which form to use, and that's important because of what I mentioned earlier.  Let's say I use the private key 5KG6rY, once with the correct uncompressed public key, and once with an incorrectly assumed compressed public key:
Code:
private: 5KG6rYdSopgYo1rejJAdPfbS6RgqhtAecg7EA19mJi9P9s2Ftru
public key (uncompressed): 04C57E907AEC9BA14D377EA1627672197A87D38A0BB12A390B1504FF9A6A941772D052906B5A5AFB908E096C1C884C0E14096BB47EAC617C99DEDADBC4AE5241F7
hash: 065A9D7AD12CA8C1962FB0E21C4E92DB86BE137E
address: 1abcCjhme96hnPDe3pDc3Ch1EnEj5Rjv7

Code:
private: 5KG6rYdSopgYo1rejJAdPfbS6RgqhtAecg7EA19mJi9P9s2Ftru
public key (compressed): 03C57E907AEC9BA14D377EA1627672197A87D38A0BB12A390B1504FF9A6A941772
hash: D4BEAF01D5E007F63FB28BF262DF1E9E3A68132B
address: 1LPtgbhspbUKVxmntmRSYzUMkpkZiHJH6w

So you can see that if you make an incorrect assumption, you end up with the alternate (non-vanity) address.
( You'd probably be searching quite a while to find a private key that yields a vanity prefix in both uncompressed and compressed, let alone the same vanity prefix Smiley )

As a general rule, you should probably be using "-F compressed", as the blockchain ends up being smaller if everybody used compressed public keys (even if it does get negated by dust, comment spam, tumblers, etc.), but either pubkey or compressed will work.

The "script" one is a parameter you can ignore unless you really want to muck about with BIP13 type transactions Smiley

( Note that the above applies to Bitcoin addresses - if you're generating for an altcoin, the -F parameter may or may not apply depending on that coin's details. )

Good afternoon.
Thank you for an answer.
but I however to the end understood how to use pubkey.
here line with the key over brought by you.
