Large Bitcoin Collider (Collision Finders Pool)

[turspro]

LBC IS DOWN ?

I do not understand - is the project working or is it being deleted?

Does someone have code for local (solo) use on the GPU?

Does someone have code for local (solo) use on the GPU?

you may want to check thread Faster and Autonomous Large Bitcoin Collider upgrade
or this thread BitCrack - A tool for brute-forcing private keys
both are utilizing GPU to (sequentially) brute force private keys of Bitcoin puzzle transaction ~32 BTC prize to who solves it
Good luck! you will definitely need a lot of luck and time to find even one of them

[digitalcitizen]

This is interesting.

Is anyone using it?  I assume they are, my LBC clients seem to be working.

If I implemented Python + CUDA implementation for Linux (eventually, still getting the hang of CUDA), would anyone be interested in testing and trying it out?

I'm also looking for why I'm not authorized to use GPUs.  Does that mean it can't access them for some reason, wrong CUDA toolkit/OpenCL lib combo, or something else?

Thanks

Greetings, newbie here.
Who can explain how does the program/server check address balances after generating?

[nutildah]

I'm curious, has anybody outside of the pool randomly found a priv key with a non-zero balance associated with it?

I saw the list of "trophies" section on the website, and at the time of the last recorded discovery of 0.54 BTC, that was about an $8,000 haul (assuming whoever found it kept the entire amount). Not bad.

To my knowledge the only keys with non-zero where the few puzzle wallets that bitcrack found ahead of LBC. At current prices that same .54 BTC would be roughly $1500 USD. Not bad haul, but I'd definitely wait for the market to go back up before cashing out

Greetings, newbie here.

LBC has a list of all wallets with non-zero balance that it checks against. Through some advanced mathematics LBC is able to check this list of several million addresses all at once at only a slightly slower rate than if it checked against a single address.

LBC IS DOWN ?

I do not understand - is the project working or is it being deleted?

LBC is not down and not being deleted any time soon, currently collectively hashing at 268.62 Mkeys/sec. If you are having problems setting it up on your machine feel free to ask questions here or on the discord server.

Advanced mathematics?!... WOW... Its more like advanced stupidity!

I find the whole thing to be pretty awesome. What are you afraid of? they might stumble upon your private key, or expose a vulnerability in the system? If so, then that's the way it was meant to be, and the next iteration of bitcoin will need to step up their game in terms of key generation and security.... "Quantum-resistant" I believe the term is.

No, that's not the term, "Quantum-resistant" means resistant to quantum computers, which Bitcoin is not. That's not the problem because there are no functional full-capacity quantum computers yet. There are some prototypes, but none delivered what's promised.

I understand that, I'm just saying that's what bitcoin would need in order to fully be sure private keys can't be brute forced as the LBC project is more or less attempting to do.

[becoin]

It is very stupid to measure the success of this "project" by how much keys it generates per second. What actually does matter is how much of the generated keys you can check against existing DB (aka blockchain) per second. Why is that so difficult to understand?

The probability of finding a bag full of dollar bills just walking down the street is much higher than finding privkey of somebody else's address. And no, finding a bag of dollar bills won't be an indicator for vulnerability in the dollar monetary system.

My take on this "project" is that from the very beginning it has very little in common with the initially proclaimed objective.

I'd have to say that becoin is right on this one, finding a vulnerability is not actually LBC's objective. LBC's objective is to "find a collision in which 2 different private keys go to the same wallet" that's it. Will this break bitcoin? No, but it will be a proof of concept that bitcoin is not as secure as most people think it is.

(And yes, advanced mathematics. Seemed like an easier explanation then starting off on a tangent about bloom filters)

[Thirdspace]

LBC's objective is to "find a collision in which 2 different private keys go to the same wallet" that's it. Will this break bitcoin? No, but it will be a proof of concept that bitcoin is not as secure as most people think it is.

I think the bolded part does not accurately describe true objective of LBC
because the keys they found are exactly the same keys used by the puzzle maker
they do use the word "collision" but they're not actually simulating a true collision
imo, they are simply brute forcing to find matching keys for addresses in the puzzle transaction

So 1: LBC started before the puzzle wallets where a thing.
And 2: The puzzle wallets have nothing to do with LBC's goals, they are just a nice bonus along the way.

Bitcrack on the other hand was made specifically to find the puzzle wallets, and so far it seems off to an excellent start. LBC is currently searching a space in which it will not find the next puzzle wallet, only an empty one that bitcrack already cleared.

The reason is bitcrack is 'only' searching for the puzzle wallets, while LBC is looking for 'any' wallet with a balance, including the puzzle wallets.

Odd, thought for sure that it was. Anyway, the other points  are still valid.

[stergos4]

Hey there, I'm new on linux. Since yesterday I am running LBC at vmware but I don't really like it because vmware tools doesn't work for copy-paste, there is not even a scrollbar on console. So I have installed Ubuntu a new machine on vmware  and all required packages as you mention on installation pages.

I have LBC perl file at downloads folder. From there I open the terminal.

I don't know what I have doing wrong but when I type:

Code:

sudo ./LBC -h

I get:

Code:

sudo: ./LBC: command not found

Installation of the packages progress:

sudo apt-get install libgmp3-dev
-
sudo apt-get update
sudo apt-get install libssl-dev
-
sudo apt install gcc
-
sudo apt install make
-
wget https://lbc.cryptoguru.org/static/client/LBC

I really like to make this work right, once I a planning to run this for a long time.

Any help would me appreciated.

Thanks in advance!

EDIT

Also tried the method via WLS and I got exactly the same issue!

Code:

test@LAPTOP:~$ ./LBC -h
-bash: ./LBC: Permission denied
test@LAPTOP:~$ sudo ./LBC -h

You have to set permissions:

Should do the trick but don't put anything personal/private on that VM.
