2^256 Deep Space Vagabond

[mc_lovin]

As hopeless as the seek for a private key with a balance on it is, I applaud the efforts of this program!

It's GPU-accelerated?

[Remember remember the 5th of November]

It's likely CPU-only.

The Deep Space Vagabond is worst than any lottery, any gambling casino, any search for alien life, and gives false hope.  Other than that it is fun. :-)

OK that settles it, I'm in.

If you mine with a CPU you will have a practically inifinite better chance of finding bitcoins than with the DSV.

Can you show me how you calculated that?

Using this calculator, http://www.alloscomp.com/bitcoin/old_calculator.php, at the current difficulty rate it will take on average only 31,145 days to find a block with a CPU which has 4200 kilohashes/second.

I don't have the maths for the DSV, but 2^256 is a lot and a computer that tries to find the private key by brute forcing it will take longer than the age of the universe.

Usually, if money is involved, thus higher motivation anyone can try to find a weakness in whatever algorithm.

So I've decompiled it, and this is what the source looks like:


1. Build the GUI
2. Output a random string of characters for the address
3. Output 0 for the balance
4. Repeat

 

Why even bother piuk

FTFY

Not like it will change anything

I guess it's just sarcasm, but if not, well I confirm that the app (v1.01)does query blockchain.info for live  address balance data.  Anyway, you can use any network sniffer worth its salt to verify this.    

That said, it's true that the current code is quite trivial and not to be taken too seriously (as announced in the OP).

 Not like it makes a big difference anyway!

Version 1.1 is out, with more intuitive operation, a custom HTTP user agent and cleaned up temporary files.

[flatfly]

Got a nice response from piuk, so that's cool! He's ok with it as long as I use a custom user agent in my request headers so he can keep an eye on the load.

I'll go ahead and further and develop this a lilttle more!

I envision DSV to eventually double up as a fast address generator, watch-only  balance checker,   dictionary-based brainwallet bruteforcer, and screensaver.

It will also support easy drag-and-drop of custom TXT lists with brainwallet sha256-formatted private keys, or 'interesting' addresses such as satoshi's addresses, top 500 rich addresses, etc

As I'm currently travelling, development will not resume immediately, though.

The Deep Space Vagabond is worst than any lottery, any gambling casino, any search for alien life, and gives false hope.  Other than that it is fun. :-)

Also, unlike all those other things, it is free!

2^256 = 0.0012 x visible atoms in universe

We're screwed!

Somehow I doubt that. I am more inclined to believe that a planet has a billion times more atoms than that number, considering a human body has a similar value, according to this article:
http://education.jlab.org/qa/mathatom_04.html

But I am no physicist.

Do the math again.

Number of atoms in the human body according to your article 2,3*10^28
2^256 ~ 10^77
Number of atoms in the universe ~ 10^80

The greatest shortcoming of the human race is our inability to understand the exponential function.

any news on when the source will be released, or atleast a github?

Before releasing it, I still need to:

 1. clean up the code (Didn't have time for that yet and it's now at it's now at 200-ish lines)

 2. look into how to prevent abuse/malicious usage once the code is public: the
    executable has some built-in throttling to avoid hitting on data sources
    too hard.

In the meantime, I may post the super-short initial Python-based version of the code (version 0.1 which was VERY slow), which was actually using Electrum servers for balance checking. Not sure if people would find that interesting.

BTW, a new feature in 1.1: you can drag and drop a text file containing a list of arbitrary addresses onto the GUI to quickly view their balances. For this to work, make sure each line begins with 8 colons and a space. For instance:

Code:

:::::::: 1DkyBEKt5S2GDtv7aQw6rQepAvnsRyHoYM 
:::::::: 1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a

If you release the source code, no one is stopping anyone to remove any throttling.

It can't be that hard to re-make anyways.

Yeah, this is what I'm worrying about. I will probably make the v0.1 code public and the current (more potent) version of the source code available on donation. But I'm not sure yet, need a few more days to think it over. And of course, I welcome any suggestions/feedback.
