...I just checked if its thread concurrency related, because it tends to mess things, but checking a few values around it seems that it isn't. This is on a 5830. Hmm.. no shares submission, just plenty of HW.

We need ig0tik3d!  Heck, maybe that whale IS ig0tik3d, LOL (joking)

[blaaaaacksuit]

Damn, wish I had a GPU!

[AlexGR]

A:0 and HW through the roof for all of us... hmm.

edit: The difficulty of the shares also seems to be broken since it rejects everything on submission... like 6/0 rejected, above target, 3/0 rejected etc.

edit2: The HW errors like these:

[08:45:37] GPU0: invalid nonce count - HW error
[08:45:38] GPU0: invalid nonce count - HW error
[08:45:38] GPU0: invalid nonce count - HW error
[08:45:39] GPU0: invalid nonce count - HW error
[08:45:39] GPU0: invalid nonce count - HW error

were high intensity related, needed lower intensities (i17 = errors, i15=ok)

[illodin]

Ugh, really?  I thought you said it would be so difficult to get the GPU version working!

difficult, not impossible, someone determined enough could do it... think about it, if you know how, and can see you could get some money out of it...

Yeah, we could consider a reasonable bounty for an open sourced GPU miner, or even GPU + CPU.

Yeah, and if there is a hardfork to add KGW, generate a lets say 10k bounty in the blockchain at the fork? Should that be incentive enough for getting a gpu miner appear?

what version of ubuntu your running? best to stick with 12.04 imho

also saw this:

Code:

/usr/include/x86_64-linux-gnu/bits/local_lim.h:39:26: fatal error: /usr/include/linux/limits.h: Permission denied

do you compile under sudo or normal user?

[Queeq]

It is indeed 12.04 server.

I ran configure without sudo. Thought it's unnecessary. Shame on me, should have tried that myself Running with sudo solves the problem.

...and the big miner stays with his gigahashes (=it's not a question of cpu profitability)...

[noobster]

someone make the miner for intel opencl? i'm sure this would give an opportunity to intel chips owners=)

[heskey]

He will stop right after the rediff to ~120.
And we'll never get another rediff with our hashrate...

there is 1 way to do a rediff... doing a hardfork.... its a bit complicated, but it can be done

It's no problem if it comes to that. We actually did that early on already, it's pretty simple.

However, I have a feeling the "whale" is just using GPUs. The X11 algos are very hardware optimized to run on a GPU and I think it would have taken someone about this much time to implement that and launch a farm. Time will tell if I'm right, but it seems likely.  

If I'm correct, the hashrate shouldn't fall when difficulty resets (not > 20%) because the cost of running that setup is minimal.

I thought this was CPU only mining?

And any thoughts on implmenting KGW?

The X11 algo should be compatible with GPUs and very difficulty to port to ASICs. I did some work on a GPU miner for X11, which is here: https://github.com/evan82/darkcoin-sgminer

I have some 7970's laying around here, I'll see if I can get it working for us

And any thoughts on implementing KGW? I think the current retargeting actually works pretty well, if we have to hard fork after this I'm not opposed to implementing something like that.

The algorithms I used for our proof-of-work came originally from here:
http://csrc.nist.gov/groups/ST/hash/sha-3/Round2/submissions_rnd2.html

This sounds like a reasonable solution. As someone said before, the cpu-folks has atleast had a fair chance to acquire a good amount.

The state of the network

Yesterday we had an eventful day and I wanted to wait and see what happened with the hashrate and difficulty before putting this update together.  For those that weren't watching we went all the way from .7Gh/s to 3.2Gh/s due to either a large farm of computers or a working implementation of a GPU miner.

Anonymous Transactions

I'm happy to annouce that we have a fully working pre-alpha implementation of the anonymous transaction technology. Yesterday I was able to send ~40 anonymous transaction using the client and the code seems to work pretty well. I'd say it's very early pre-alpha, but it's 100% certain we'll be the first fully anonymous coin that exists.

The next stage of development is to deal with some bugs and other technicial issues I have in the code that will allow it to run without encountering issues. Currently, I have to reset the pool after every transaction and that needs to happen automatically across the network.

After that we're going to beat up the code up and harden it in a open pre-alpha. The code will only work on testnet during all of the next stages of development and we'll be giving out binary clients that can only connect to the testnet.

Then, we'll go through alpha/beta and then implement a full release of the code into the client.

Open Source or Closed Source?

Last night we were talking in #darkcoin (join us!) about 2 possibilities for launching the anonymous technology:

1.) We launch open source and hope we gain a good name in the community. If done correctly, all of the other coins will just be clones that don't add anything original. I would still be working on other functionality and improvements, so we'd always be ahead of the rest.

2.) We implement all of the unique technology as a closed source plugin. The plugin would be shipped separately and added to a folder to enable the privacy features, it would also work normally if it didn't find the plugin. This is how NVidia ships their closed source drivers for their video cards with linux.

Which should it be?

Thanks to all of those that had some faith in the project early on, the prospects of this coin are starting to look really promising.

[MyFarm]

Open source please.

[illodin]

Closed source at first, no question. Then after few months when DarkCoin has become de-facto anonymous transfers enabling currency release the source.

If people don't trust their whole wallet balance to the closed source plugin, they can have their main wallet running without the plugin, and xfer the amounts they want to transfer anonymously to the another wallet with the plugin.

im standing behind this one as well, closed in the beginning so that we can get this coin well established

Closed source mate. Protect the milestone to avoid lazy cloning. Cryptos are being churnned out like rabbit babies right now with next to no innovation. I suggest you fore stall that trend a bit as we fight for legitimacy.

[Queeq]

Would it be possible to further modify the algorithm so it becomes completely impossible to mine on GPUs? Needless to say that most of people would prefer mining on CPUs as deploying GPU farms or having even a single GPU loaded at 100% is not possible for typical user.

Regarding open/closed source, experience says that open is always better than closed.
