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

[Kangaderoo]

Over the years I've seen requests for P2SH multisignature vanity addresses.
The basic support of Vanitygen was a 1 signature out of 1 key P2SH address.
I thought it was time to add more multisignature support :-)

The code for the following proof can be found in my https://github.com/kangaderoo/vanitygen repository.

As I'm a puzzle solver, not a software professional, my github repository has a fixed setup to my personal environment and does
not automatically configure to other development environments. My personal environment also does not support OpenCL, so this
part of the code is not updated.

I think getting something working with an FPGA would be the likely next step.

Do you think that an FPGA would apply for this task?

Do you think that an FPGA would apply for this task?

Someone would need to code a implementation of this https://github.com/samr7/vanitygen/blob/master/calc_addrs.cl in Verilog. I don't know much about FPGAs but they must also choose the right pins to assign to. I like the idea though, since there should be a way to program the EC multiplications and adds for it.

[bitcoinwhoswho]

with an average setup how long would you expect it to take before finding a vanity address like 1ELonMUSK14JSGNYAcPJNqubuFByZPyjcj? Or 1SPacex1daUkw7L6ux8Cfw7jASexb9umL?

I would be interested in that, too. Is there a calculator with which you can roughly determine how much time you need with a certain setup for a certain number of characters? I did a address generation for four characters today, which took me around 25 minutes. For a generation of six characters, I unfortunately had to quit the generation after around 4 hours.

[nc50lc]

Here: https://en.bitcoin.it/wiki/Vanitygen#Using_a_vanity_address_generator_to_try_to_attack_addresses
The table is based from 1Mkeys/s. Just adjust the 'average time' based on your "average set-up"

Based from that, it's 1year for 1ELonMUSK & 3hours for 1SPacex if Vanitygen is running at 1Mkeys/s.
Take note that there's luck involved in that, you can get your address within the first few minutes if you're extremely lucky as long as the difficulty isn't too high.

 There is a faster prefix search program called VanitySearch (developed by Jean_Luc)
Using a GTX970 GeForce GPU, the search rate went from ~40 Mkeys/s with Vanitygen to ~240 Mkeys/s by switching to VanitySearch.   I was thinking about buying a second video card to increase my search capability when I stumbled on Jean_Luc's program.  The program itself gave me a nearly 6X increase in speed where another $400+ GPU would have only doubled the speed.  The energy savings are also amazing as I no longer need to leave the computer running for days to find the desired prefix.

In August of 2018 I created 2 vanity wallets.  In March 2019 they were hacked and my 1.2BTC was stolen.  Don't trust vanity wallets.  I used bitcoin vanity Gen. -snip-

That's the problem, you've used the scam website bitcoinvanitygen, there are a lot of scam accusations againt that website and the user who's promoting (or creator of) it.
Vanity addresses are considered secured as long as there's nothing malicious in the code or your private key isn't compromised.

Link to the trust rating of the user who's promoting that site in his signature: Trust Summary: Velkro

[student4ever]

I have a problem:

ocl vanitygen runs at a speed of 4000 Mk/s on my rig and today he printed out some thing like this - numbers are for example:

index found: 553
CPU hash: 123456789
GPU hash: 123456789

Delta found: 1234567 Delta started again: 123456

I have 2 identical hashes, but he did not sow the PrivK.
How can I get to the adress and privK with this information?
I also have the prefix of the adress, since it shows me the index number of my prefix search file.

[GoVanza]

I have a my own generator (for Linux) that produces private key + address but not in base58 format.

I have another program in Python too that produces private key + address, I should search it. I don't remember performance, but surely much more than 1500keys/s. Are you interested?

This smells like jhdscript will soon open a new topic: 'Please Help! My Bitcoins have been stolen.'
My answer might be: 'Sorry for your loss'

Thanks for the trust.  

Anyway my program generates only "consecutive" keys. You provide:

1) the private key to start from
2) how many keys you want to compute

and it generates the corresponding addresses (hash of public keys, not base58 encoded). This is the output if you start from key = 1:

It is only up to the user to choose which keys to generate, not up to the program.

Besides I don't think that jhdscript needs to store a so huge amount of addresses to send some bitcoin there. Maybe it is only a statistical project.


@jhdscript

I made 2 tests (writing speed, Xeon CPU E3-1505 3 GHz + SSD, Ubuntu Mate 17.04)

1) supervanitygen:  about 220K keys / minute (8 threads,  that confirms that vanitygen-like program are not suited to your case)

2) my own generator: 75M keys / minute (-> 6,5GB file / minute) per 1 core. I got about 175 Mkeys / minute with 4 cores.

Unfortunately if I try to compile it for Windows the results I get are not correct anymore.  When I will have more time I will give it a look. For now I can't help you  (unless you decide to use Linux).
Honestly I can't figure out why you need to fill an hard disk so fast. It takes about 20 hours to fill 4TB.

Hello! Could you share your program for me? For me, such a speed of geniation is like flying to the moon! I want to try this miracle program! I would be very grateful to you! Thank you very much!!!

Vanitygen is giving me a wrong private key for my IXC address. Is there a way to fix that without editing the source code?

Thanks in advance.

Vanitygen is giving me a wrong private key for my IXC address. Is there a way to fix that without editing the source code?

Thanks in advance.

I just take a peek at IXC announcment thread and looks like the developer merely change the prefix from 1 to x.

Assuming my speculation is correct, it might be because vanitygen uses private key format (WIF with prefix 5) which indicate usage of uncompressed public key while most wallet would create compressed public key by default.

Thanks for answering.

The issue I see is that it gives me a wrong prefix for the private keys (i.e M, N and L) when it should be a 5 or K, L as you say. I believe the length is wrong also, 50 characters, when they should be either 51 or 52.

[nc50lc]

Vanitygen is giving me a wrong private key for my IXC address. Is there a way to fix that without editing the source code?

AFAIK, you should be able to use the result of vanitygen to IXC,
if '1' isn't useable, you should convert the address manually by 'BASE58 decode' the address then change the network bytes and checksum.
The private key should be the same as Bitcoin WIF prv key (uncompressed) based from an IXC paper wallet generator (link).

Everything you said here aren't what vanitygen would produce. Vanitygen's result WIF prvkey for mainnet will always start with '5' consisting of 51-characters.
Are you sure that you're using the right binary (from OP) or commands?

Are you using this to bruteforce a private key? Bec. it's not recommended for that.

Well, that is what vanitygen is producing for IXC, other coins seem fine. Yes, I am using the right binary from the OP. No, I am not using it to bruteforce a private key.

This is the command I'm running: ./vanitygen -X 138 xabcd

[nc50lc]

This is the command I'm running: ./vanitygen -X 138 xabcd

Okay, seems like there's something wrong with Vanitygen when it comes with Altcoins, but there's a workaround to that.

You can convert the result invalid WIF private key into the correct format by base58-decoding it into HEX, remove the checksum and network bytes,
and you got the private key.
Then covert that into WIF by doing vice-versa but this time, use "0x80" instead of '0x0A' in front.

This page automates all of that, displays an example and the steps: https://gobittest.appspot.com/PrivateKey,
Just paste the N, M or L WIF prvkey to the first text box, hit "send", and the result will be displayed under "Private key to wallet import format" at step #7.
But it's not available offline, if you want a secure method, find a script or something.

this address has more than 2000 bitcoins, it was created using this program? How long did the process take? If you can create such an address, can you use the full address to calculate the private key?

1CounterpartyXXXXXXXXXXXXXXXUWLpVr

this address has more than 2000 bitcoins, it was created using this program? How long did the process take? If you can create such an address, can you use the full address to calculate the private key? 

That is a burn address like 1BitcoinEaterAddressDontSendf59kuE, or 1111111111111111111114oLvT2 (all-zero Hash160).  It is constructed in such a way as to make it obvious that nobody has the private key.  Funds sent to such addresses are irretrievably lost.

Here is a valid Segwit burn address, with all-zero Hash160:  bc1qqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqqq9e75rs.  Funds sent to this address are irretrievably lost.

The 1CounterpartyXXXXXXXXXXXXXXXUWLpVr address was created specifically for Counterparty’s proof-of-burn protocol.

The supply of XCP was created in a process called ‘proof-of-burn’ that lasted from January 2nd to February 3rd 2014 (5000 Bitcoin blocks). During this period, anyone was able to exchange bitcoins for XCP automatically on a protocol level under the following conditions:

• Users sent their BTC to a verifiably unspendable Bitcoin address with no known private key. (1CounterpartyXXXXXXXXXXXXXXXUWLpVr)
• Each BTC was automatically exchanged for a number of XCP between 1000 and 1500, with more being rewarded the earlier the burn took place.

Stupid, in my opinion.  Nobody can ever spend that money.  It permanently spams the UTXO set for people who actually use Bitcoin.  But—well, now you know the purpose of that address.

No, Vanitygen cannot crack its private key.  You are welcome to try, with that or any other address.  Have fun. :-)

HTH.

[BlackHatCoiner]

@alevlaslo, generally when you see coins on addresses that look like this: 1xxxxxxxxxxxxxxxxxxxxxxxxxy1kmdGr, they are gone forever. If we ever find a way to get the private key for that address (if there is any), we will face much more worse problems than those you can imagine.

Stupid, in my opinion.  Nobody can ever spend that money.

Let the stupid ones burn their bitcoins. They make them more valuable without knowing it.
