But once you have an address you can use firstbits.com for a shortened version and it allows using wrong case. I just checked and 1teflon isn't used by anyone yet so if you send a few cents to yourself on that address then you'll own 1teflon.

1Love - ya, lots of them out there. 4 chars is pretty easy to generate quickly.

Yup. BTC addresses can't contain a lower case "l". And a few other letters too.
I guess you'll have to use 1TefLon.

You don't. Each new address also has a new private key. Start with a simple example to see you have done it right,

For CPU: vanitygen64 1Love
For GPU: oclvanitygen -d 0 1Love

That should spit out an address/key pair in a few seconds typically. If it works then you can try longer ones and other options.

You only supply a "hex public key" as input when using -P to generate a partial key for a third party.

You should try something like 1PZjfkLZBT7Q3UFmyEWH8QtuzTMi3MUiBj. If you succeed you have a big reward.

First, what OS are you using? For Windows there is binaries on the vanitygen github so it should be pretty easy to download and just use. For Linux or OSX you'd have to compile I believe. I just did that again after 9 months when I first did it and it's fairly easy/painless.


Go here,
https://github.com/samr7/vanitygen/downloads

For Linux/OSX click Download as Tar.gz
For Windows binaries click the vanitygen-0.19-win.zip link.

I have 3x 5830s here. But this rate was with my mining still going. So it was quoting me about 4 Mkeys/s and when I shutdown mining I can get around 22 Mkeys/s. So factor in about 5x faster if you dedicate the GPU.

ie. on 3 GPU miner dedicated you get this down to 5678 / 5 / 3 = 378 years.

The character length is super critical. Even cutting off one char makes a big impact.

So oclvanitygen -id 0 1Sitonme

quotes me  only 3.3 days.

For CPU:
vanitygen 1Sitonmyface

But that would take forever. Well, ok just 258759000 years on my mahcine.

For GPU:
oclvanitygen -d 0 1Sitonmyface

Ah, much better, only 2819089 years.

The -d 0 option on oclvanitygen just tells it to use the first GPU device.
You can use -i if you don't care about case sensitive.

oclvanitygen -id 0 1Sitonmyface

Which estimates 5678 years. Much more doable.

All these time estimates are based on 50% chance of finding.

Since no one, as far as I know, have built support for third party generation of vanity addresses without the person generating the address also knowing the private key I'd strongly recommend against doing this. Not only will people need to trust you, if anything happens later they'll most certainly believe you scammed them.

(Did my build instructions for Mac still work or did they need updating?)

y u no like ponys teflone. lol

For those of us scrolling through the thread on our phones, it would be great to collect all the winners in the original post...just a thought...things like scrolling through 20+ pages or using the search feature is a major PITA.
