Just trust me it is IMPOSSIBLE to get same address as somebody else. Its just impossible even if u have world most powerful computer.

Lol, maybe you're just abusing the phrase but 'just trust me' is exactly the kind of answer I'm repulsed by in this context.  I'm trying to educate myself about some abstruse facts and mere "I'm right" claims aren't convincing at all.

Furthermore, you still seem to be missing the difference between the definition of IMPOSSIBLE and IMPROBABLE.  I've got nothing against you personally but it doesn't seem like you're the best source to go to for the maths on this one.

Cheers.

Ah well i just wanted to make it simple Cheesy LOL. I used word impossible coz it rly is , well ok it maybe isn't in theory.

Here u can get rly good education about it http://en.bitcoinwiki.org/Main_Page . Im just sleepy and baing lazy to make rly good post about that and how big ur chances are Smiley . So i say its impossible coz it rly is and u dont have to worry about how safe it is to make vanity addy coz somebody might make the same. Coz that was ur question.

FWIW, the probability of rolling a "4" 1 million times in a row is infinitely greater than 0.  Something with a probability of 0 is impossible.  Something with a probability greater than 0 is not impossible, no matter how small.  IMHO, conflating impossible with improbable really muddies the waters in these kinds of discussions, so I'm trying to avoid that.
Well, if we're going to get technical... you can't divide by zero, so you can't say that it's infinitely greater than zero Wink

But yes, I know what you're saying, and I almost corrected Micro myself before you replied.  However, there's an equal muddying of the waters when you say that there's 'a possibility' when the layman doesn't really understand just how incredibly small that possibility is.  In their mind 'a possibility' means that it is, in fact, likely.. that all it would take is a supercomputer.  Something about people not quite fully grasping the really, really small and really, really large things.  I'm not immune to that either - I can't wrap my head around the size of the universe (as far as we understand it), nor around things like poisons that need only a pinhead's worth to kill you.

Thus, "for all practical purposes, you can consider that to be on the level of 'impossible'."

As for the rest - yep, you got it.

Note that I should place an asterisk beside my suggestion that you can't tell a program to only generate addresses that match a certain criteria, as some people have tried to attack a similar problem (Bitcoin mining) using SAT solvers.  However, I'm not convinced their approach is actually fundamentally different and when I looked at it last, it would give an imperceivable advantage on a small stage of the process - while implementation in an ASIC would be nightmarish at best, so it has no practical purpose there.  I can't readily imagine a situation in which it would be of help in vanity address generation either, but my math only goes so far Smiley

Thanks for the reply MICRO, but I'm suspicious about your information because it seems vague and lacking in detail.  For example, you say that something is impossible but I think you mean infeasibly improbable.
Yes, that's what they meant.  Note that for all practical purposes, you can consider that to be on the level of 'impossible'.  I.e. say you roll a million dice - is it possible that you'll roll a 4 on all million?  Sure, it's possible.  Now consider that the issue we're discussing here is several magnitudes more difficult still Smiley


I just cant look at it that way . I must say its impossible at that chance Smiley . Maybe wont be in like 100 years with some new super computers. But atm even if u combine all computers on this planet they cant do it.

But ur explanation is rly good. Tnx.

Well, if we're going to get technical... you can't divide by zero, so you can't say that it's infinitely greater than zero Wink

Good point, that's a subtle mistake, but you're right.  In my mind, I was thinking about the fact that division by zero is undefined, but I made a mistake by suggesting that that implies a nonfinite relation between the result of division by zero and some number.  In fact, you simply can't compare NaN with a number.  Nevertheless, I think this strengthens my real point which was that you can't get any closer to impossible by making a small probability even smaller.  Likewise, multiplying a finite number so many times that it becomes inconceivably large doesn't get you any closer to infinitely large.

I should have specified that I wasn't looking for the layman's version.

Thanks for the follow up.  If you know of a good thread with the techinical details, drop me a link.  I think MICRO's link to the main page of the bitcoin wiki is only so helpful Smiley

I downloaded the latest version and compiled it for OSX but I can't seem to specify a public address when I use ./oclvanitygen (or the miner) instead of ./vanitygen however the topic start of mentions it's both possible. What am I missing? -P doesn't seem to be an option for oclvanitygen.

Hey guys. I was wondering if it was possible to make a 1 click set up/app or a step by step guide for setting this up on Mac. I would really like to be able to make some vanity address but I do not know how to build from source or any of that kinda stuff...

Thanks

Aren't there binaries for osx for vanitygen?  In any case it's not too hard to build from source, I use GNU/Linux but as OSX is also unix based, I suppose the steps would be pretty similar:

1) wget http://locationofsource/tarball.tgz
2) tar -xfzf tarball.tgz
3) cd tarball
4) ./configure && make && (sudo) make install

I think you could figure out the mac specific stuff in like 20 minutes of reading, just google 'build environment osx'

I found this tutorial for MAC OSX and it works for me.

http://www.stanley-adams.co.uk/2013/12/custom-vanity-bitcoin-address/

Run vanitygen:
Code:

How do you use these addresses with bitcoin core ?

If you generated them yourself and want to make use of it from your wallet, you'll have to import the private key:
https://en.bitcoin.it/wiki/How_to_import_private_keys#Using_bitcoind
( see note about v7 - instructions for that are on a different page at this time )

If you just need to send funds to one, it's the same as any other address.

And will probably steel all btc same as last site that done same thing .
They store private keys and part private keys.

http://bitcoinvanitygen.com/ probably is using your software
Probably - nothing wrong with that either.

I do think the way it's set up might be problematic.  For one thing, I'm not seeing a field for a customer to provide their split key part.  That means that the service could (not saying they are, but they could) be holding on to the keys for the generated vanity addresses.  Even if they don't, they could still get hacked and the hackers get access to keys from there (this has happened before with another service).

I certainly caution against this service's use until they implement split key generation.

Best to stick to one of the other services that do offer split key generation;

The fact that they do not offer split key generation says enough.
Do not use http://bitcoinvanitygen.com/!!!

Yep.  Hopefully its proprietor (Velkro? If not, I'd be happy to drop them a line at the e-mail address) can add split key generation, as aside from that it is fairly well-setup with concise instructions on how to import the keys, offering a paper wallet to print out, etc.  VAMP ( http://vanityamp.com/ ) was almost like that, with a very polished interface, and based more on outsourced vanity mining (ala vanitypool) - that's still under reconstruction, though.

Just as been done with (SHA256 and Scrypt) mining software, I've been trying to port the Vanitygen code for CPU to make use of the SIDM functionality.
By running the SHA256 and RMD160 4 times parallel (AVX1) I got a rough speed increase of about 25-30%.
It seems that the actual EC_key generation is the big time consumer.
Any idea how to speed this up?
Is it possible/faster to only calculate only a X-coordinate, hash the compressed key, and try to find a (valid) key-pair after a confirmation
a wanted prefix in the bitcoin address is found? You might run into false positives I guess, but this could be a trade off to faster hashing.....

Code is @ https://github.com/kangaderoo/vanitygen

Does anyone know if this means that doge and litecoin split keys are not possible with this? or do I have to read through the entire codebase?

Correct - it always attempts to spit out a Bitcoin address.  I only had a cursory glance at some of the forks, but it doesn't look like anybody actually touched keyconv to support altcoin addresses.  BAU also doesn't support it, nor does bitaddress.org's code (though that's javascript, shouldn't be terrible to modify).

Looks like somebody should have things going, though;

I checked the source code of the keyconv, it only combines two private keys an generates a new key.
For the address verification it assumes the prefix that is related to bitcoin, for some reason the -X option is not here for various address confirmations.
For combining the private keys it is actually not needed.

So I took your bitcoin adress to the site: http://brainwallet.org/#converter
convert the bitcoin to hex
input = base58, output is hex
Code:
1GHeVSRy4CiSnrCwydCJ3yMVJszpZfEELB ==> 00a7afd6658acf743094ad9458033b77ab2c4ead4572a7dfd4
replace the 00 prefix (bitcoin) for 1e (equal to 30.. I suppose dogecoin)
copy the result in the input box
input = hex, output is base 58
Code:
1ea7afd6658acf743094ad9458033b77ab2c4ead4572a7dfd4 ==> DLRk2hNcMccjKrPYiDBrbjX6C1j7tgjDpX

Inserting this private key in a Dogecoin wallet should give the prefix DLR I guess.....If the hashing is the same..
the generated code:
DLRk2hNcMccjKrPYiDBrbjX6C1j7r1Pnkg
is not 100% equal to the actual code
DLRk2hNcMccjKrPYiDBrbjX6C1j7tgjDpX

Thats because the SHA hash checksum is not calculated in prefix mode to gain time, this effect is only at the end of the address.
