Any specific distro and I will setup my server with a linux VM.
Will run 24/7

Anything non-archaic should do.
LBC requires Perl 5.16 or newer, but that has been released 2012 (http://perldoc.perl.org/perlhist.html), so there should be no problems in any modern Linux distro.
Unless you run of course Debian Wheezy - which has 5.14

A modern Ubuntu or OpenSUSE should probably be the way of least resistance.

It doesn't matter what your clock shows. Looks like you're dreaming 24 hours a day.

Do you simply not understand the concept of geeks sinking a bunch of time into a project because they enjoy it?

For example, people are still working on cracking the RC5-72 challenge even though there's little point to it now, and no possibility of making money off it.

News:

A rudimentary prototype (id: b63a29558c76b37d6523ad729052544b) running on Amazon EC2 t2.micro instances:

Code:

[ec2-user@ip-1xx-xxx-xx-xx ~]$ ./LBC-hrd -c 1 -t 960
 done.
Fetching adequate work... got block interval [1368933-1369103]
ooo

Speed is around 186413 pk/s (allegedly CPU E5-2670 v2 @ 2.50GHz)
edit: Yeah, but with the CPU credits being eaten up really fast, this sh*t drops dead to 4004 CPU levels. Note to self: There's no hardware like own hardware.

memory usage around 550MB

Code:

ec2-user 27097  0.0  2.3 193768 23584 pts/1    S+   10:35   0:00 perl ./LBC-hrd -c 1 -t 960
ec2-user 27148 84.4 51.6 527308 526964 pts/1   R+   10:45   0:05 ./hrd-core -I ... -b funds_h160.blf

I got a free t2.micro instance for 12 months, you may too.

---------------

Pool speed now around 14 mio pk/s and we haven't started yet. The new generator prototype is running only on 3 systems so far.

If you want the new client, you can have an early package. This weekend. Here's how:

you have a CPU with AVX2 or at least "Westmere" architecture.
you have Linux 64bit
if you have Windows, install a VM with 64bit Linux
you are in the LBC-Top20 and can run at least 1 core 24/7
you PM me with the id of your client
you get a download link (~180MB) and deployment instructions.

I cannot guarantee the availability of a native Windows version in the foreseeable future. Even with the running VM, you'd benefit greatly from the way faster performance and way less memory requirement. Even together with the VM, your total memory requirement for 4 processes should be around 2.5GB

I don't see the answer to my question. Who's gonna pay?

You. You will pay for all of this. Dearly. Roll Eyes

Seriously - I seem not to understand your question. If by "you" in "your efforts" you meant me personally: then I did answer. If you meant one aka pool user, then read the FAQ.

All I can see is hope that a racket scheme will bring some money in future. But a racket to work you have to punish people that don't comply. Can you show us at least one example of such a punishment?

I have the privilege to make a very rich wife happy. Cool

Ok - seriously: Some day I hope to set up a protection racket scheme with this pool, where everyone with significant funds tells me their private key, so I can mask it from the pools search space. Every client then gets a message "this block is protected". Advanced DRM will make sure the client obeys the servers' directive.

Right now, the client wouldn't (-p -), but I will keep the nice gizmo features coming, so everyone will eventually update to a version which will have DRM implemented.

...(here you have time to calibrate your irony detectors)...

Your question is valid though. Let's just say I'm well funded already. You can hire me for 0.1BTC/h but that's only the special bitcointalk.org rate for my ngah brethren. Usually its 0.3BTC/h. This allows me to invest my spare time (when no one can afford me, or when I fuck off stupid projects) into things I like. As - at the moment - I cannot do yet another crypto-exchange, I'm doing this.

Hope this answers your question - nice quotes around "effort" though.

I don't see the answer to my question. Who's gonna pay? How will you generate income to pay back?

I also used the supervanitygen from gandalf, but i'm not sure if u can use more than one thread when u set a defined starting PK. The supervanitygen will genrerate the same PK on each thread, or am I wrong?
By the way, would be nice to know, how you get the supervanitygen code ready to create uncompressed addresses!

The new generator will be an evolutionary descendant of father brainflayer and mother supervanitygen.
Or vice versa - I'm not sure.

It'll be mostly based on supervanitygen - it has a bunch of very nice optimizations for fast incremental searching, and I've been hacking on the code for other projects.

Although I believe Ryan Castellucci should have the last word, we want to name it to depict the process of lifetime burning/burnout of stars.
If anyone has an intelligent idea how to name it - come forward.
Current contestants:

HRD-core
Kardashev

It requires only 512MB per process, but there are some strings attached.

Just setup my Windows Client to run.

Its only using 30% of the CPU which I dont understand.
All 4 cores should be in use.

Will have this PC run 24/7 with this on.
Can you tell me why I am not using 99% of my CPU on this?

I'm curious how did rico666 achieved 13x speed increase, for me it looks like 3 ways:

1. Do less hashing, but we already are at the point of minimum operations (pubkey->RIPEMD160, bye-bye base58)
2. Golang code optimizations (less function-calling, using maps, etc.)
3. Completely new host application(?)

Anyway, it'd be great to try new client version, currently running 12 cores + 4 cores on LBC project, can rise up to 27-30 cores (maximum of 52, lack of RAM on some machines), should we expect to see it released today? Wink

I'm ready for testing Grin

I have my work PC running atm with blocks from 875780 to 875919.

Its a bit slow PC so its not doing much..

But when I get home tonight I will setup my windows client with an i7, 8gb ram that can run 24/7 for this project.

Do you have some reading material so newbies can get into this and help with the development of this?

EDIT:

For those who have intrest in doing this or need helping setting up their first little collider I can help you with it.

I also want to ask those who are willing to send me a PM so we can setup a communications channel for everybody involved to help development further and get news out to all the users faster.

We can use the following tools (That I know of): Slack, Skype and Discord as messages are saved and you can get up to speed fast.

I am ready to work as a test subject with both servers and high end computers available with different kinds of GPUs.
I sent you a PM already

Subjects to be experimented upon are always welcome. However, please be aware that this thing has grown beyond the point where I can give individual support or Skype-chats for installation and similar.

Actually I think there are quite some experienced client operators out there, so if you have trouble installing/operating, ask here and let's see if the community can help. I'll jump in to save the day if necessary.

The Large Bitcoin Collider (LBC - a.k.a. Collision Finders Pool) is a distributed effort to find private keys to BTC addresses that have funds on them.

The effective search space until something (except bounties) is found is 136.75 bits. Given current search speed, the probability to find an address with funds on it within the next 24h is 0.0000000000000000004524764939984744324231018884855317923702%.

... this number will start to exhibit geometric growth.

4 days later... one night of the new prototype operation on a single notebook kicks in:

0.00000000000000012534589518698458834533715456585961112532%

Let's have a look:

0.00000000000000012534589518698458834533715456585961112532 /
0.0000000000000000004524764939984744324231018884855317923702 = 277.02189362218494374282

Today, the probability to find something within 24h, is 277 times bigger than it was 4 days ago.

(Of course, this will not prevent our professional mathematicians here to point out how small that probability still is. Compared to - say - being struck by lightning, or spontaneous incineration or something like that.) Wink

edit 3 days later (Sep 24th):

0.00000000000000430421645392984254453591906477587101993978752 /
0.0000000000000000004524764939984744324231018884855317923702 = 9512.57471055359313336432

Hey Rico, just wanted to thank you for your effort put in to get users like me into the project on windows, it seems like it was alot of work to bring us in ;p
i am trying to do the pool proud, will be in the 5 digits here soon Cheesy

tht script works well for me btw, damn tho, 4 instances runs even 16GB of DDR4 RAM high (80%), Cheesy

these are the projects i love personally, non-profit, "what if we CAN?" projects

Thank you - my biggest motivation is the what if.

The 4 instances should take "only" 8GB, at least that's my interpretation of the task manager output.

wow tho, WHO is top place? must have some servers to do some work heehee

Indeed, some 10-14 CPU SMP servers. Doesn't matter, because soon my notebook will be top place. Wink

It seems this pool will soon check more keys daily than it has checked for its whole life time so far (40 days). Soon. Mark my words.

Observe client 1ff65d1e0f08af7529e9c9f0a591f263 @ http://lbc.cryptoguru.org:5000/stats

That's my notebook testing a new prototype. Currently its 4 CPUs are responsible for roughly 50% of the pools capacity.
That's right: a speedup of ~13 to 16 ... still not GPU ... all CPU.
However, t's quite a change and I will have to test it longer.
