Hi,

Actinium developer here. Smiley



Hey Brak thanks for the hard work! I was able to salvage half my mined coins the other half (in the privkey i posted above as a bounty) were snapped up by someone else. Hopefully they join and help the community Smiley take care!

$MAID & $BTC other than that some short hodls and some long held garbage.

Many thanks for your kind words and sorry for any inconvenience, but we have no influence over those external tools. At least the one project I mentioned above now officially supports Actinium.

And I too hope that our little community will soon get more members. We hope that our transparency will attract people who are into crypto not only because of quick gains. Making money is ok and we want our users to become wealthier, but ideally they should also stay with us! Smiley

We're currently waiting for Ledger HQ's response regarding our Ledger Nano Integration.

Let's hope the best!

Best regards,

ACTINIUM ➢✈✅[No Premine]✅[No ICO]✅[Fair Launch]✈★

Sorry to insist, but are you sure? How do compressed private keys (introduced in bitcoind/bitcoin-qt 0.6.0) fit in there? From what I've been able to read, vanitygen doesn't support them and they are actually separate from noncompressed keys (ie, can't be expressed as normal uncompressed base58 keys) - so what proportion of the 2^256 search range do they represent? Or am I totally misunderstanding compressed keys?

Yes you are misunderstanding the compressed keys.

Uncompressed key is a pair of (X,Y) EC point coordinates prefixed with 04.

Compressed key is just X coordinate of the same point prefixed with 03 if Y is odd or 02 if it is even.

Then the key is hashed as: ripemd160(sha256()), which gives you a (bitcoin) address.

You can actually hash a string of any length, so it is not evident what do you mean by "can't be expressed as ...".

This tool is quite amazing.

The thing i don't understand is how is even possible to get an address with a pattern we want. I didn't read into the code yet (i see is quite complicated) but, aren't private keys of two address wich differ  just by these chars occuring in the same position *piggy* or *piggp* completely different? So how is it finding those patterns so relatively fast?

If was already answered somewhere please point me to the answer, thanks.

EDIT: found some good explanation with some more details in here: https://en.bitcoin.it/wiki/Vanitygen

Hi

I don't understand what the -Z option does ?

-Z <prefix>   Private key prefix in hex (vipco.in)

is it related to mining vipcoins?

Also I have question:
When vanitygen  generates a coin  address matching a <pattern>,  is it possible to limit the search within a certain range and not  the full
 256bit range of the private key ?

Any thoughts?

 Thanks for sharing.

hey,

found this project today and tried it out.
so i ran vanitygen on the pattern "1", expecting it would write every address it generates to the out-file, what it did.

but when i tried oclvanitygen, it creates masses of addresses, but writes only very few (1 per second) to the out-file.
Whats wrong?

How do I search for random private keys?
even if it is practically impossible to find I would like to test

I suppose you could just type in '1' and no other characters. This would be random. You can then add an argument that tells vanitygen to repeat step as well as write them in a text file.

Thanks for reading my post.

Hello!

I'm a beginner and I will not be able to compile program oclvanitygen.exe and vanitygen64.exe

I want to ask you to compile your program with one change

in pattern.c
=======================
      if (i == zero_prefix) {
         if (c == 0) {
            /* Add another zero prefix */
            zero_prefix++;
            if (zero_prefix > 50) {
               fprintf(stderr,
                  "Prefix '%s' is too long\n",
                  pfx);
               goto out;
            }
            continue;
         }
========================
Put the number 50 instead of 19.
if (zero_prefix> 50)

Thanks in advance.

If I understand correctly, this increases the maximum number of characters to search for from 19 to 50, correct?
If so, you can just safe yourself the trouble: it's never going to happen!
But if you still want to try, you can just as well search for "only" the first 19 characters. If there is a hit, which takes somewhere around a quintillion years, you can manually verify the remaining characters to see if they are correct too.

Yes, I need 50 number of characters
I know that the generation itself is 2 ^ 256

I need a program with this change.
Can you help?

You're missing my point: what you want, is not possible.
If it would be possible to brute-force private keys, Bitcoin wouldn't exist. You can try this for the rest of your life, but you'll never find what you're looking for. So safe yourself the trouble and don't bother.

I'm not trying to say what's possible or not. Will you be able to compile these programs for me with the changes I need?
I do not want to plant a flame here.
If you can help, you will be plus a hundred in karma.

The problem is solved. De-seeded the binaries, found the place of the number, replaced it with 50 by binaries.

I know I asked a few months ago. Does anyone have the performance numbers running oclvanitygen on a GTX1050 vs 1050ti ?
OR
The RX 550 vs 560?
They are all going to cost me the same more or less but I figure if someone has the answer it will save me the time of mucking about.
Thanks,
Dave

Since PIVX already exists in one of the vanitygen builds, you would have to base it off of here:
