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

[deisik]

Yeah... in general, most of the 3's are from web wallets, where you don't own the private keys... places like Xapo, Coinbase etc...  and the 1's are your typical one private key per address type wallets from your desktop/mobile/brain/paper wallets etc...

Having said that, some web wallets (like old blockchain.info) where you had the private keys were 1's... and some of the nonweb wallets that support multisig will generate 3's... so you can't really say 100% what sort of wallet generated any particular address...

The 1 and 3 certainly has nothing to do with vanity or not.

Does it mean that vanitygen can generate addresses starting with 3, i.e. multisig addresses (which would seemingly break the concept of such an address)? If it can't, there is only one way that it can have anything to do with such addresses...

That it just has nothing to do with them

You can generate a Wallet Address starting (seemingly) with any letter of the Alphabet or Numeral.

ONLY "1's" and "3's" can be used with BitCoin Wallets (glossing over the test mode version of BitCoin for the moment).

 They're not valid bitcoin addresses because they were generated as Pay-to-Pub-Key-Hash addresses with a 3 prefix rather than a 1

The only way that you should be able to generate a vanity p2sh address would be to make 1 of 1 multsig addresses. T

So what's the conclusion? Vanitygen can't be used to generate multisig addresses, right? Then how are these addresses generated? I mean, before all, how the concept of multisig private keys is honored during key generation?

Or someone should necessarily hold all the keys to such an address initially (say, an exchange owner)?

  Vanitygen simply does a brute force on random P2PKH addresses and checks them for your desired prefix.  An implementation that brute forces random multisig P2SH addresses could accomplish the same task but it would be considerably slower.  I think you could still use 2 of 3 (or any number really).  Anybody want to take this on?

It would be possible, but you would end up having to brute force 3 keys instead of 1, which multiplies the possible search space by 6. Since it would also be a script, the script could also just have a nonce, and then you could also keep incrementing the nonce until the address is something you like.

 I like your idea for the nonce.  That would speed up the process rather than having to create new addresses each time.
I'm pretty rusty with my programming skills but I'm going to have a look at vanitygen and see how difficult this would be.

-snip-
With the exception of brainwallets, generating a random address and checking the totalReceived or balance the odds are not favorable, at all.

So why do I do it? For fun, duh. And I am a persistent fuck, lol.

Just out of curiosity, is that still the java I hacked together for you?

thanks samr7, got my 1PizzaYSVynFNubFexqwrTXvDp8NJSJiap address in few minutes! I love it!

I need to make a series of 5 letter vanity addresses. In order to do so I think there's a command and I do something with bracket (Yes. I definitely completely understand what I'm doing /s).

Question: Can I use the same HEX public key '04AC6402...' if I'm doing split key vanity gen to create a series of vanity addresses?

So what I mean is my public key is '04AC6402...' can I use that to create multiple addresses, all at the same time?

1test1
1test2
1test3

Let me know if you understand what I'm asking and if it makes sense. Basically I'm trying to save some time rather than generating 100 addresses on an Ubuntu Live USB then going to Vanitygen and 1 by 1 find the part private key.

If you generate addresses for yourself you dont need to use split key vanity.

Anyway, here is the command to create 1test1 to 1test9 (cant do 10 because there is no 0 in base 58).

Code:

./vanitygen 1test1 1test2 1test3 1test4 1test5 1test6 1test7 1test8 1test9

You can also create a file with all the prefixes, e.g. "my_prefixes.txt"

Code:

./vanitygen -f my_prefixes.txt 
Next match difficulty: 1702005001 (9 prefixes)

If you only want a single address from any of the possible prefixes use the -1 flag, e.g.

Code:

./vanitygen -1 -f my_prefixes.txt 
Next match difficulty: 1702005001 (9 prefixes)

Edit: I just got the part you said about brackets and I think you are refering to regular expressions. Its possible to use them (flag is -r, but they will slow you down.

Code:

$ ./vanitygen -1 -f my_prefixes.txt 
Next match difficulty: 1702005001 (9 prefixes)
[419.17 Kkey/s][total 4964864][Prob 0.3%][50% in 46.7min]
$ ./vanitygen -1 -r 1test[1-9]
[151.59 Kkey/s][total 582912]

If you generate addresses for yourself you dont need to use split key vanit.

Anyway, here is the command to create 1test1 to 1test9 (cant do 10 because there is no 0 in base 58).

Yes I know I don't need to use split key, but I don't trust the system I'm on so I just generate the original addresses on an Ubuntu Live USB to be extra secure.

I actually didn't even think that I couldn't do 10... or any multiple of 10. Hmmm. I'll have to figure that out. Maybe I'll just use characters after 1-9. That way I don't have to add an extra letter to save some time anyways 



I'm going to do a little test and see how this works. BRB AFK! Lol.

You can use 'o' (small Oh) instead. Its the closest in terms of looks.

Hi, is there a way I can tell vanitygen to start the search at a specific privatekey (hex value ...), and not random?

For example all adrdesses with prefix: '123456' beginnig search at privatekey (hex value 10) 5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreBoNWTw6
and then 11, 12, 13 ....? And not random?

So if my harddisk crashes i can retrieve the privatekeys back, cause i know which range i used?

[Chris!]

Meh. I just don't like the look! I'll probably do capitals. Haha then of course I'll get to (I) and be screwed all over again. Hmmm what a predicament.

Another noob question. Like REALLY noob so don't laugh. How do I tell if I have a GPU in the laptop? I'm assuming I don't have one at all but have no idea how to check. Why am I asking? It just took my CPU... 7 minutes to find a 4 character vanity address hahaha.

Maybe this will help you finding what GPU you have.

Yeah, its not easy sometimes with the limitation of symbols.

(Assuming Ubuntu) Try
lspci -vnn | grep VGA
 on a linux shell. If it says something about nVidia or AMD there is chance you can use oclvanitygen. If its an intel GPU you likely cant.

Thats not how vanitygen works. The private keys are created randomly and there is no progress you can lose.
