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

[LoyceV]

Are Vanitygen less safe than random Adresses since they were bruteforced?

No.

if Vanitygen would always start a bruteforce from 0000000

It doesn't.

Think of it this way: instead of generating 1 random private key, you generate a billion random private keys. Then, you choose the one address you like, and use the private key that belongs to it. In the end, you still end up with a random private key.

Thank you, i thought they all start from the same point instead of always being random from the beginning! That helps

How much processing power do you need to run a vanity generator/miner today? I would guess it will use lots of electricity for the task.

How much processing power do you need to run a vanity generator/miner today? I would guess it will use lots of electricity for the task.

The same processing power you needed from day 1 of bitcoin's existence.

Like people explained above, you're just randomly sweeping through millions of bitcoin addresses to find one that fits your criteria. It doesn't get worse as time goes. In fact, the chance of you colliding and finding a vanity address someone else used probably went up by a micro-nano-milli-trillion zeroes percent, so good luck!

You can use any device, but some are faster than others. My A8-7410 laptop CPU searches through ~200kkeys/sec, my Ryzen 5 1600 @ 3.7 GHz searches through ~2Mkeys/sec, and my GTX 1060 3 GB searches through ~40Mkey/sec.

-snip- my GTX 1060 3 GB searches through ~40Mkey/sec.

What is the Operating System that you're using?
It's usually 30~ish Mkey/sec for me on a 1060 (Windows7 SP2 updated with drivers).

@martinadoulet The question is how long you're willing to wait for the result; talking about processing power, even a Core2Duo™ is enough to make a personalized 4-1st-characters vanitygen address within an hour or less if you're lucky. And that's way below the power consumption of an AC.

Windows 10 Pro build 17134, Nvidia's latest Game Ready drivers (v418.81) and the Lifeboat version of oclvanitygen. I'm also running an EVGA GTX 1060 SC which is a bit higher clocked than stock cards (1.607 GHz base/1.835 GHz boost versus stock at 1.506 GHz base/1.708 GHz boost) which could account for the differences.

Anyone tried to run on W10 and AMD cards maybe?

the hole vanity shit is a bad idea! Always use a new address to send and always a new to receive. -- END --

That is Bitcoin! All other use is stupid!

Well, I disagree here, at least to the first part. And in my opinion, there a quite a few very good use cases for vanity addresses or at least where it makes no difference to use a vanity address or not. I don't see a problem to receive small donations or signature campaign rewards to a vanity address, where your address is public on the site / forum anyways. Or it's a good thing to use it on Bitcointalk to stake your Bitcoin address and secure your account in case you get hacked. For doing so you don't even have to send Bitcoin to this vanity address.

Even if you are not planning to use your vanity address it's a very good way for everyone to get a feeling how impossible it is to guess (brute-force) another private key. Everyone can try it on his own device.

I tried this a long while ago but ran into troubles on Mac when trying oclvanitygen.

Samr7 stopped development of vanitygen, what is currently the best github repo to get a version that works on Mac?

[BurtW]

Have anybody try to run vanitygen on Google's TPU cloud machine or any HPC service? What's the best keysearch rates has it archive so far?

Why would you run it online? It is risky to do that because your data could be intercepted.
You should run vanitygen offline on a secure computer. Using OpenCL is fast enough for me.

I think his point is Google's TPU or HPU can generate vanity address at faster rate. While it's true that the information could be intercepted, using encrypted connection could solve the problem.

Using split key is a much better solution, so that Google itself can't know your private key either. They can still know you generated the address through.

I totally forget about split key. But google knowing user generate vanity address doesn't matter unless you could know bitcoin address just from partial private key, brute force to get private from an address with partial private key or have serious privacy concern.

Here is an old thread from 2012 where we all discussed how outsourcing vanity address generation could be done.  The math is discussed there if you want to read up on it.

Later, most of us in the thread gave up on the idea since anyone who cares about fungibility wants to get rid of address reuse all together.  Ideally all addresses would get used exactly two times:  once to fund it and once to spend it.

This flies in the face of the entire concept of vanity address generation.

So anyways, I've solved 1BruJoLoKo while searching for a lot of other prefixes:

1BruJoLoKozkJmSktkYUhxZiwj8R7ShaED

PM me if interested, I have the private key (just not part private key)


According to the search page BTC 0.0144 is valued at

Not exactly a true vanity address, but I have played with using "private vanity addresses" which are kinda like a vanity address if you know how to "unlock" it.  (e.g. sha256(address || privateSeed)  starts with 0x000000  or something.

And you have the privacy aspects of a normal address, but you (and anyone you give the privateSeed to) have a very quick way of knowing if an address is yours (with a small amount of false positives). It's pretty sweet for scanning the blockchain for instance (just discard everything that doesn't match your private vanity address).

is there a video guide for noobs? i wish i could search for random privatekeys (i just want to waste my time)

It would literally be a waste of your time on levels I don’t think you’re fully comprehending. You’re much better off spending the money you would have wasted on electricity on lotto tickets if gambling is your thing.

I can't find any video guide (actually I didn't searched). But there's a comprehensive guide in the Beginners and Help board.
Link: [Guide] How to create your customized Bitcoin-Address (vanitygen) – step by step.
It's fool-proof, even your cat can follow it.

Good luck on finding private keys and tell us if you find one, contact me after 9999999999999999999 years

I put up a website listing all the bitcoin addresses with balances, sorted from the most to the least,

https://bitkeys.work

You can see, the top address has 122K BTC in it. You can try to vanitygen your addresses by targeting those address, and good luck in some years.

Nice
It could be interesting to have the public key (if exposed) instead of a random priv key.
Which is for instance the case for the first address with 122,804BTC:
Pubkey: 03c931af9f331b7a9eb2737667880dacb91428906fbffad0173819a873172d21c4

hello, i'm interested why gpu can't quickly generate addresses with low difficult, command for example:

./oclvanitygen -C BTC -o results.txt -i -D 0:0 -k 1
