Hence my warning ...

Rune (sp_) is not about the commmunity like you are, he is about himself.

#crysx

No - not a crack at you at all ...

You at least supply Source in Git.

I am directing almost all of that at sp_ (a guy by the name of Rune Stensland) who always crawls out from under his stone when he thinks that people have forgotten or otherwise are busy with other things, where he comes out with a 'Private' coded app and either sells it, gives it away for later purchases, or just plain codes it to benefit himself. He has no interest whatsoever in 'helping' otherwise the coding would all be done in Git and supplied as opensource. ALWAYS watch out for this guy - he has ALWAYS been shifty character and ALWAYS made money off PEOPLE, not his work. Especially in the days of Algo Optimization where my friend (and at the time work colleague for us at CWI) Alexis )known as Alexis78) showed Rune what it was to REALLY code Algo's and optimize them. Also releasing most of the code as OpenSource - which almost ALL of the CUDA GPU miners are based on today.

Alexis and I are STILL friends, STILL work together on certain projects, and STILL despise what Rune is consistently doing every few months or so.

So be careful of this guy Rune / sp_ as he is NOT for the community and ONLY for himself. You have all been warned!

As for the app you are writing - we can most certainly discuss and work together for a MUCH improved version as well as a verifiable Community edition package, unlike those of which Rune is pushing.

Chrome on Windows does that for all exe files that aren't signed. I haven't seen this behavior on Mac or Linux, probably because on Windows the browser assumes that you're downloading a virus.

---

I wanted to run the spmod2 Bitcrack on my T4, on Linux, but there is no source code to compile from.

Linux cracking speed has the potential to be much faster than Windows because there's no GUI that's using GPU cycles.

Ha...ha...ha...unless I am reading what you are saying wrong.  You have 20 cards, round about 20? And you think you would crack 10%?  The pool has been running pretty non stop for over a year. With Zielar's big push at times with 256 to 512 V100, and they are barely above 10%.  Yes. 256 up to 512 V100s at times...over a year running, and barely above 10%.

How can use GeForce GT 640 with CUDA please advice ?

I use GeForce GT 720 but can not use CUDA
my GeForce GT 720 can use only OpenCL
if can use CUDA may be better faster

Kaspersky scan not found virus is ok

but if download from google chrome may be get warning about download from internet and recommend to delete out

try download from opera or other browser

Will test.

3090:

Even if he is able to 2x the openCL speed on the Ampere cards, it would take my spare -/+20 cards 74 days to crack 10% of the puzzle 64. Could be enough, but prob. still would take a lot of time.

Btw _sp
I can remote access you a RTX card if it helps.

Okay, but it looks pointless for me.
This code is for arbitrary puzzle output number (n):

If the original bitcrack did 9.4 MKey/s on the GT 640, does that mean your mod will do 100000000000 MKey/s on the 3070?
Seemed like you were comparing the speed of a 640 against a 1080Ti...

No viruses found in my bitcrack exe files.

I have sent you the file to test, but nobody has reported the speed yet. #2 Should work on the gtx 750ti from 2014 and newer nvidia gpu's

Some pascal results (compressed):

gtx 1050: 50 Mkey (laptop?)
gtx 1070: 370 MKey
gtx 1070ti: 404Mkey
gtx 1080ti: 600Mkey
Titanx pascal: 560Mkey


The original bitcrack does 9.4 Mkey on the (GeForce GT 640) . So the 1080ti with the sp-mod #2 is 63 times faster.

Oh wasn't ment like that, I just wanted to share some people cannot open the file in the first place. I just did some quick test.
I couldn't find the commit history sadly enough? The files are empty, for me at least.
Was searching for it, to see how / what he changed. We're talking about this repo, right? https://github.com/sp-hash/Bitcrack

In binary notation we make arbitrary decimal numbers from powers of two like this:

00000110

represents 6, or 4+2, in binary.

With a list of 2^n*G points, to make 6G you'd just compute 2G+4G which is fast since you already have those factors.

To make any arbitrary point from a factor, you take the lowest bit and see if that's equal to one and not zero. That means you have to add "1G". Then you right shift the entire number, for example into this:

00000011

Then see if the lowest bit is one again, this time it means there is a 2G term you have to add.

Repeat the process to check if you have to add 4G, 8G and so on and you can make any arbitrary point in log2(n) time.


Thank you for the kind words. But I think I'd have an easier time operating a pool if other people were involved, even I have to sleep too you know


I don't think it has malware. Anti-viruses are known to make bullshit false flags on crypto software and miners in particular (which we'll inevitably see happening if Stratum urls and networking are added). Besides, the sp-mod commit history is on Github so if he really were up to something shady then we'd already see it by now.

*Shit there is only a README file in the repository, the source code is available as an asset on the releases page, but I have to get on desktop to read it.

Only way you’ll see me party a pool with my GPUs is when NotATether is the only, verified, owner. Based of the open and honesty he shares in the findings and improving CUDA, it’s a no-brainer he’s here to improve everyone.

Regarding the sp-mod, your V2 link has a Trojan in it per Win10 findings (conteban).
Your V1 doesn’t run on ampere. 3060, 3070, 3080 or 3090.

Nevertheless nice to see some activity on it again 
Very curious what the fix would be.

Are you looking for uncompressed or compressed?
Since I do not know your purpose in this, I can't help you to shorten the pubs.
Regardless, 20 million priv keys and corresponding pubkeys should only take up about 2.5Gb in storage space.

In my experience the 2 TB will fill up quickly within 2 min if speed of 15 billion achieved and if i write private key and corresponding public key , i ran a test today with python script which was slow but i was looking for space that it acquires. At 20 Million keypairs , it took around 17 GB space and 1 and half hour . Writing to disk was not a problem since it was not generating at that fast speed but at 15B a minute , it wont be possible since write speed of My SSD is merely 2GBps whereas at 15B its throwing data at 190 Gbps . I hope my calculations are not wrong. Any other suggestions please.



In the same file as combined.txt


Can you please explain this ? Suppose i got all 2^n and 2^n*G till required N. Lets take it as 30 for now. In that case if i have to find k*G derived from K 700000003 which is between 2^29 and 2^30 , how would i , since i dont know K value. It will require me to go through all K. Ofcourse it will be easier using point additions and i think this is what existing libraries like secp259k1 do but this wont help in case of looking up thousands of pubkeys at once.

I didn't get your point of jump tables and point lookup in hashtable using factor as index thing. Sounds interesting though.

Seems like I missed quite a discussion going on here  


Yeah I didn't mean to imply that everyone's going to be paying a fixed reward, people are actually less likely to mine [keys? I like that phrase  ] at pools that'll only give them a fixed amount of money.


One of my wild fantasies is to learn OpenCL to make a version of the Kangaroo Int class that runs on AMD cards. Sadly for now it remains a fantasy as I got my hands tied with what I'm now going to call "Kangaroo-256", and I'm already learning CUDA the hard way - through trial and error. I don't expect OpenCL to be any different.

Before this I didn't think Telariust VanitySearch-Bitcrack combo was legit, or at the very least I thought it was some rudimentary mishmash whose sum was less than the parts. Nice to know I have something else to open up my eyes to as well.


Definitely not me that's for sure. I know this is not an accusation at me obviously

Actually y'all can take a stab at what I'm working on at https://gitea.datahoarding.agency/ZenulAbidin/Kangaroo-256 on my own git server and not on github cause this is still alpha and I didn't feel like pushing broken code to Github.

This'll eventually hit github when it's completely finished.

I have some other commits beyond this at local particularly on the GPU side of things but I'm not quite done with them yet (there is a nasty segfault I have to debug).

I think it's a step in the right direction.

Thanks ...

Will have a look at this over the coming week.

As for connection - Skype is the best way to get me. Alternately, the CWI Discord Server in the Details Page of the Main CWI BCTThread in my Sig.

Easy to setup, open source

https://github.com/Etayson/BC_server-client

Even has checks and balances of "fake" shares/submits by creating a key in each range that is checked/verified. Same as other pool.

Interested in ideas...always.

I am not a coder - just tinker ...

I have coders working/helping in a team. They are the REAL professionals in this space, not me. I am however the idea and deal maker. The owner and the visionary behind all that has been built thus far. Always looking and listening and always taking on board advice from the professionals that do the work and code that I need.

In saying this though, I know nothing of a pool system that crunches these keys. If I did, I would have one setup a long time ago - all open source.

I guess the difference is that when you trust the pool operator/owner, then that is the point of failure, but also the strength if that person is solid.

There are ways to increase the compute power by levels of magnitude, and I know what some of those are, but need the coders to do the coding to bring these things to life. I guess when I am more serious about committing resources to such a project, I will look for more of those type of coders. Till then, is there any Pool Software at all that could be setup for complete transaprency of what is being done?

#crysx

pool scan already 1 Quadrillion from all 9 Quadrillion
but pool not have much for active user
I think pool need more active user
