Faster and Autonomous Large Bitcoin Collider upgrade

RIP LBC, RIP vanitygen 

Vanitygen's main purpose if for creating personalized address, not to bruteforce private keys.

But I second this: RIP LBC 'after 104 more addresses'.
It's been dead for a long time though, there are only few users left who's actually "adding" a share (for the Puzzle).
Most are just brought there by curiosity and false hope.

Can someone show me the pk no 161 - 256 ?

Private keys?  It's not possible. Only the transaction's author know them.

[holy_ship]

Arulbero's magic proggie can calculate PK of spent puzzle56 because 2^55 - 2^56 is relatively small range.

puzzle161 is spent, but the range 2^161 - 2^162 is 40564819207303340847894502572032 times larger

nc50lc, you should read at least first page before commenting in topic.

I can search a private key in a 2^70 range, not much more. It takes a lot of memory and cpu power.

arulbero, can you send your script or the source code of the program with baby-giant step? I'm not a programmer, I'm just a system administrator, but I have a test server with xeon and 1tb ram. I think that 1tb is enough to compose a hash for about 2 ^ 110. And if my assumptions are correct, then I can search the keys from 2 ^ 160-2 ^ 220

1 TB is only 2^5 times 32 GB (the Ram of my laptop). You could search maybe until 2^80, probably less, I have a Xeon too.

I wrote that program for myself, it is "unusable" at the moment (too hard to configure, no comments) for anybody but the author (me).

Theoretically CUDA doesn't have noticeable advantage over OPENCL.

It has inline assembler though.

oclvanitygen is for GPUs. For CPU you need to use Vanitygen.

[anunnaki1202]

How to do that ?
To just removing ocl?

Nope, oclvanitygen and vanitygen are 2 different programs.  Read the following thread, you will understand what I'm saying: https://bitcointalk.org/index.php?topic=25804.0

Try -D 1:1

then wait "bitcrack" cpu version https://github.com/brichard19/BitCrack/issues/71 or try on python 3 to create your own programs there for a couple of weeks to study. https://bitcointalk.org/index.php?topic=1306983.msg45861254#msg45861254

[holy_ship]

Don't listen to ignorant andzhig.
Theoretically it should work on CPU or Intel GPU, NDV said that he made some fixes to original vg code.
You should use NDV OCL version, but you have to setup OCL drivers for CPU first.
I haven't tried.

I don't think it makes sense now, when puzzles 55-57 are found.
phrase "Xeon CPUs, not the best, but alright. I was getting at least 33.6 million keys/sec on a 96-CPU machine." from
https://github.com/brichard19/BitCrack/issues/40
dunno who is this. Maybe UnknownHostname dude and crappy LBC software.
But still,  it only makes sense to search with several GPUs now, not 48CPU cores. Even if they are free/stolen.

[Andzhig]

I'm not "ignorant")), if his mind didn’t have enough drivers to install, then the sense before him to grovel, for me, it works on cpu with -D 1:1. But bitcrack has an advantage at the moment besides speed, it can run multiple copies of the program on the same device, the total speed is divided between the programs equally, on 1080ti, can run 100 programs on one card with speed 1-2mk\s, this allows a larger scatter range to scan simultaneously ().

holy_ship does it make sense what i wrote you in pm for the search space ?

and how can i install the Bitcrack or should i only download the exe file from github ?

[holy_ship]

on 1080ti, can run 100 programs on one card with speed 1-2mk\s, this allows a larger scatter range to scan simultaneously ().

Are you sure that overall speed is not lower with 100 copies?
You can easily do the same with simplest scripts and switches
-s, --start             Staring key, in hex
-r, --range             Number of keys to search
to scan each range at full speed, then skip to next.
