Faster and Autonomous Large Bitcoin Collider upgrade

[Yahkinator]

To reiterate, using

Code:

oclvanitygen -D 0:0 -f addresses.txt -o found.txt -k lastkey.txt 0000000000000000000000000000000000000000000000000000000000003000

should reveal the addresses for the first 14 puzzle transactions within seconds.  It doesn't.

try on cpu -D 1:1

It's an integrated video card.  It won't be the final machine I'll be using...just testing.
@holy_ship do you have an opinion?

I guess these zillions of leading zeros transform your HEX to some crapy WIF.
Also HEX should be uppercase, at least in Linux.

oclvanitygen -D 0:0 -f addresses.txt -o found.txt -k lastkey.txt 3000
Start with 3000
Searching for 160 addresses
81920/131072
[1.70 Mkey/s][total 44564480]

Removed the leading zeros.  Capitalized the numbers. 
Still doesn't find anything.
Can you share a command line that returns a find?

Do you still need funding to improve the speed?

You can request updates from NDV directly, if you wish. He promised 30-50% boost after rewriting ECC code for around $300-400.
You can make the change public or personal.

If you are going to use big farm it makes sense. For 1-2 cards (like I have) it's just easier to buy more hardware.

I haven't tried intel gpu, also I didn't even try windows.
The command looks fine, although -D 0:0 is not necessary.

On nvidia card I've tested first 30 and 52,53,54,55 puzzles - works like a charm.

[Yahkinator]

Fired up my Ubuntu and dowloaded the code.  Running an Nvidia card in that box.  Compiled it and ran the same command:

oclvanitygen -D 0:0 -f addresses.txt -o found.txt -k lastkey.txt 3000

Still doesn't find anything. 

What's the command you ran to have those return positive?

[keychainX]

Yes, we are going to make a farm.

What is his mail, do you have it, can you PM?

[holy_ship]

I found him on upwork.

The command is OK.
Are you really talking about NDV fork of oclvanitygen ?
Do addresses.txt file contain 160 bounty addresses? Case of chars matters.

There is a verbose switch. Post the log.

I got it working on Ubuntu.  I was running LBC at the same time, and they were fighting for memory.  Still no go on the Windows version, but it's popping a CPU check error.  Might be because I'm using an integrated card for testing.  Some time this week I'll throw a couple ATI cards in the box and see if those will work through windows.

Thanks for the help and thanks for setting this up!

[holy_ship]

In verbose mode it always complains on CPU, even when working OK and finding everything.
I didn't ask him what this complain means.

If something is not working it is possible that he will fix it for free if you report a bug on github. Because he was doing this work partially for portfolio

Thanks Holy_Ship, managed to contact him

I have it running on several machines now.  Pulled the latest bitcoin address with balance file and am looking for anything that has 10btc or more.  Pulling in 142k addresses does knock about 10% off my hashing speed, but it's still much faster than LBC was on a P5000.  It actually uses all of the video card instead of being CPU bound.  If it could use a bloom filter like LBC does, it would be even faster and look for more.

Thanks for doing this.

[holy_ship]

There is of course a bloom filter in VG, but it's implementation is tuned for around 10k addresses.
Mostly it's my fault - I thought that there are 10-20 thousand of fat addresses. Was wrong.

So, this part of VG can also be upgraded. Actually, this guy spent only couple of weeks on it. He looks like a pro, but a freelancer, not charity fund There were many things to do, but I wasn't ready to spend more, than $500

I've come across 40.000+ Brainwallets, what is your target list size?

The chance to actually generate the private keys for a particular bitcoin address is infinitesimal.

There are exactly 2^160 possible addresses. 2^160 is 1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976.

To put that in perspective, there are only 2^63 grains of sand on all of the beaches of the Earth.

You'd have a better chance to mine solo on a cpu

Is rico666's original Large Bitcoin Collider dead? There was so much activity on it before, but after the FUD that there was a backdoor in it, I think the users got scared.
