So if you had a supercomputer you would basically create a pool of your own resources, but no-one has that much hash - So why not join a pool and build a supercomputer together?

To me, cracking the puzzle is not really about the prize but I find it exciting to see how long it takes and what methods people use to crack it. like picking a lock. Plenty of people pick locks as a hobby

I was actually looking at going for an RNG implementation, but I did not know whether to create the whole key or just part of the key on the GPU but it appears the whole key is better.


Thanks for looking, I will check them out also.

Thank you I will check them out.


I am working with Rust but for example sake, on PyOpenCL I have previously used "enqueue_copy" to copy a GPU Buffer back to host Memory, you are correct however that to make the program more streamlined and faster I should really fill this buffer before pulling anything back to the host otherwise I will be wasting precious time.

Hi,

I am looking at creating Bitcoin addresses in OpenCL but I am wondering what is the best way to go about it.

Should I look to do all the computation of the address on the GPU starting with the secp256k1 keypair or should I only be looking at creating the keypair on GPU and the other functions on the CPU once returned?

I am new to GPU programming and I am trying to understand the costly part of the process. If anyone experienced with either OpenCL or Cuda could point me in the right direction I would really appreciate that.

There are just so many ranges on Puzzle #66 that its near impossible to solo.

Stats from ttdsales pool below in my sig.

Total Ranges Checked: 92,272 of 33,554,432
Total Private Keys Checked: 101.45414 Quadrillion
Percentage completed: 0.274992%

the ttd pool is using a customised vanitygen for cracking, source is available in the files on the site. seems to work quicker than Bitcrack. Worth trying out even if not with the pool, I found big improvements on the 2080 Ti's and 3070's not as much on the 3090's but still faster.

-b 80 -t 256 -p 2048 works well, I found 80 compute units from the AMD site (RTFM! right.) I tried any threads higher and the GPU hung. I will have a play and get back to you, but thank you very much.

So there is some trust needed involved but the way they are doing it, using hashcat and hashtopolis is a genuine method to pool resources for cracking the hashes, there is also the fact they have to send your their hashes locally before you crack them. It really is not different than with other pool owners except its not stratum so we know the hash is not going elsewhere.

Its unique in its method and I am willing to give it a shot for a while instead of using bitcrack with no luck for the past 6 months.

Hi All,

I have a AMD 6900 XT and am using https://github.com/Uzlopak/BitCrackOpenCL/

I am wondering if anyone could help with the settings, I cant seem to get them right at all.

I tried the current settings above for Nvidia but being roughly same power I assumed same settings might be slightly compatible.

-b 82 -t 256 -p 2096

Appreciate any help.

You also do not know that your hash is not being proxied to another pool.

Cobras cant be trusted at the best of times, let alone when he is acting weirder than usual.

This is quite cheap for what it is.

How much would it cost (I am a newb at this so could use the help) to make something equivalent to an antminer - pcb wise and then fit the housing / fans / power yourself?

Still looking for work. I have done lots of crypto work before - payment integration, pool setup, complete sites / services.

I am happy to do any work before payment should you escrow the funds. Depending on size and type of project, if its only a couple of hours I am happy to do work and then you pay.

it might be easier to use a service like Blockcypher to create transactions rather than full on bitpay. but essentially anything internal does not need to be broadcast, it could just moved around in the database until someone wants to withdraw.

Bought, will be a bit of fun. Thank you!

I once made a miner from my Python FPGA, il be honest, it was not great but it kept me busy for a few weeks

Great project, would you be looking at selling any prototypes? I would be very interested in testing them out.

I do a lot of work on embedded pharmaceutical product security / pen testing etc and would be interested in looking at these.

I think its a good idea, it's just such a big project for equity, whoever the developer is might literally get NOTHING out of 250+ hours work if not more.

Bump, Looking for any technical, Linux, dev (Python, PHP) or security work. Consultation work included.

Hey,

I am currently saving up for my wedding later on this year - Although its now paid for we are still a few things short and we are looking to buy a house so I am after any work.

I am an experienced engineer, I am a professional security manager / analyst (Still technical). I have experience in many Security products including Crowdstrike, SentinalOne, PAM, multiple SIEM's, Vulnerability management software and windows and linux hardening. I also have experience in GRC, particularly around pharma and European law.

I have also worked in DevOps roles and still do a lot of Development in PHP, Python and Powershell. Including Web Dev.

I am after any kind of work including consulting, I would rather use escrow (Trusted from forum) or you pay first, or half first, I been scammed many times.

I also have an abundance of experience with open source security tools so I can increase the security posture of your company / business or even home almost instantly.

Let me know what you need. I have a linked in profile for anyone who wants proof of credentials and can prove my workplace by email.

Just out of interest.

If I was to create a bitcoin address randomly with Bitcoin Core, Would that be created in a particular higher keyspace - 8000000000000000000000000000000000000000...ffffffffffffffffffffffffffffffffffff ffff (2159...2160-1) for example? or higher? or could it be anywhere in the whole keyspace?

For the last 10 - 12 years I have been BIG into Geocaching. I have hid quite a few.

I am from the UK and would be more than willing to place some about.

Is there anything specific you would like me to add in the capsules? Maybe a link to this thread or even a note how to get started in BTC / Crypto?
