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

[Red Emerald]

So I just started running oclvanityminer on half my cards and already got a payout!  Very cool.

One problem though, when I try to ctrl+c the program, the process goes defunct and goes to 100% CPU.  Is there a better way to quit?

I can generate 1Love but I can not generate 1love. I guess that "l" (small L) is forbidden character. Why?

It's Base 58

Address is in Base58Check encoding, there are some chars forbidden: https://en.bitcoin.it/wiki/Base58Check_encoding

Thank you!

So, no 0 (zero), O (big o), I (big i), and l (small L).

Addresses can't contain "O", "0", "l" and "I". I'll let you guess why.

So I haven't had oclvanityminer lock up on me again.  It's been quitting properly with ctrl+c.

I noticed that if I run 2 instances of the miner on the same card, I get a higher total mkey/s.  I tried playing around with --threads to get the same effect, but that must not be what I thought.

Right now I have 3 instances of oclvanityminer running across 5 gpus and I get ~125 mkey/s instead of ~111.

I submitted a pull request to samr7/vanitygen containing two commits for oclvanityminer. The first changes the confusing and incorrectly stated work value as BTC/MKeyHr to simply BTC/MKey. The other commit adds a statement displaying the total value for the chosen group of work (pubkeybatch) after parsing the list of work and before starting to work on it:

Code:

"\nTotal value for current work: %f BTC/Mkey\n"

This gives the user an idea how much they are currently expected to earn. Since neither vanitypool nor the oclvanityminer client show this anywhere, the user has to guess or calculate it themselves.

I also wrote some scripts to calculate this, make some graphs, and make the data available to others in an API. You can find these at http://fizzisist.com/mining-value. I hope someone finds these useful.

I get a SSL connect error after I enter the Bounty pool URL and my address.
How can I solve this?

From the source:

Code:

//
// Why base-58 instead of standard base-64 encoding?
// - Don't want 0OIl characters that look the same in some fonts and
//      could be used to create visually identical looking account numbers.
// - A string with non-alphanumeric characters is not as easily accepted as an account number.
// - E-mail usually won't line-break if there's no punctuation to break at.
// - Doubleclicking selects the whole number as one word if it's all alphanumeric.

What was your URL? It should be https://vanitypool.appspot.com/

Been trying the same thing for an hour, any other suggestions? I'd really appreciate it.

Please help me understand this:

Just started experimenting with samr7/oclvanityminer and have dedicated a 5850 to the task. According to the calculator, I'll earn a little over .11BTC per day with this card doing normal (non-vanity) mining.

It's currently hashing around 20.20 Mkey/s and working on this problem:

"1vanity" Reward: 0.079600 Value: 0.000323 BTC/MkeyHr.

So that's 0.000323 * 20.20 * 24 = 0.1565904 BTC, right? So I should be earning more than I would if I mined straight? But then they take 20 percent out first or does that figure already have the 20 percent taken out?

It also says 50% in 8.0h, I take that to mean there's a 50 percent chance it will find the solution in 8 hours. So approximately 100% (statistically) in 16 hours, that means the reward (0.796) for 16 hours average work?  So 24/16 * 0.0796 BTC = 0.1194 BTC which is not close to 0.1565904 BTC. Where is my math failing?

Does my Mkey/s look reasonable for that card?

If I flip a coin once, it has a 50% chance of landing on heads. That doesn't mean that the second flip has a 100% chance of landing on heads. 50% chance in the first eight hours and a 50% chance in the second eight hours = 75% chance in 16 hours.

You earn nothing if you don't find the person a vanity address; you earn the reward just once if you do. The value calculation is just to help you decide if it's worth trying.

That is a reasonable hashrate for your card. You can increase both the GPU core overclock and GPU RAM overclock to the maximum possible to extract the highest hashrate.

I was interested in this too and realized there was very little out there to help people figure this out, so I wrote some scripts to do the calculations for me: http://fizzisist.com/mining-value

As for the statistical stuff, the BTC/Mkey stuff is the number you should be using. This is the expected earnings on average with the current pool of work. It doesn't matter how long you mine for (although as you mine for longer time, your earnings will approach that of the average, yet can be subject to huge statistical variance over short time periods). Bitcoin solo mining has the same problem, so pools were invented. Unfortunately, vanity pool isn't a pool in the same sense, so you still have quite a bit of variance, although MUCH less than solo mining bitcoins.

Hi wigglyuk,

Do you use an HTTP proxy?

Oclvanitygen uses libcurl, and unfortunately it won't read your proxy settings for MSIE or Firefox.  If you need to set a proxy, you can set the http_proxy or HTTPS_PROXY environment variables.  For example:

Code:

H:\>set HTTPS_PROXY="http://172.16.0.1:8080/"
H:\>oclvanityminer -u https://vanitypool.appspot.com -a 1XXXXXXXXXXXXXXXXXXXX

[samr7]

I finally had a chance to look at the source and apparently the units of the "value" shown are simply BTC/Mkey, but multiplied by 3600, or in code:

Code:

wip->value = (reward * 1000000.0 * 3600.0) / difficulty;

This is not BTC/MKeyHr, this is a meaningless number. More correctly, you could say the units are BTC*s/Mkey*hr. I suggest removing the 3600 and just displaying the value as BTC/Mkey. If the number is too small (too many decimals to be easily readable), change it to BTC/Gkey, since most people are calculating at least a Gkey every minute. If you would like to go one step further, you can show BTC/hr as:

Code:

3600 * rate * reward / difficulty

Where rate is the calculated Mkey/s for your hardware (so vg_output_timing() will have to been called already).

Hi fizzisist,

You're right, it's an entirely arbitrary and not 100% correctly labelled unit.  I just wanted it to display some semi-comparable notion of value.  The idea was to create something along the lines of kilowatt-hours, whereas the proper unit would be megajoules, but the power company doesn't publish their electricity rates per megajoule.

Anyway, I'll take your patch on GitHub to convert the display unit to GKeys.  Thanks!

I find it strange that I get 25 Mkey/s on Windows 7, but only 20 Mkey/s on linux. I tried upgrading to the bleeding edge xorg PPA and that made no difference.
