@danbi: i'm using the CPU miner from here http://www.groestlcoin.org/pools/
basically the same one as before with groestl algo, so I expected the "yays"
it also doesn't show the workers on the pool dashboard

edit: it seems to work:
I just need to figure out if that single pc is enough to warrant electricity

@devs: I've tested the wallet crashing on multiple machines now and can confirm: a new wallet seems to work! old ones just dont

I've allready found a block for the pool but it doesn't shown there.

Is there any difference between the algos used for DMD and GRS? Because there are a number of working GRS stratum pools, some of them with NOMP:

grs.cryptohunger.com
groestlcoin.biz

for example.

as far as i read from groestlcoin forum pools need a special stratum
maybe u read throught their btt thread

edit:

is this helping?

There is clearly a problem with either NOMP (unlikely, as the GRS people are using it successfully) or the DMD wallet's implementation of submit block.

You are therefore not advised to mine anymore at dmdpool.digsys.bg as the blocks we find are all rejected by the daemon.

Hope to have some solution for this soon.

Any nodes? 

@HR of course.
->different wallets for different cryptocurrencies
->haven't yet tried multiple wallets because I didn't need it

I mentioned SSDs mainly because you usually only want the most important data like the OS and whatever professional applications you need on SSD drives since they have a. shorter lifetime and b. don't have terabytes as HDDs nowadays.
That's why I always put all cryptocurrency related stuff on HDDS with the datadir parameter.

I found out that the datadir parameter works though. It was included since the original bitcoin wallet (i think.. at least I started with it).
The wallet also works with a new wallet.dat as I've stated somewhere above. Not useful tho, but hopefully it helps you.

The error message from the german guy some pages earlier is the same I get occasionally by the way. Right now it's not open long enough to actually do anything with it anyway.

Thanks for keeping this active and gn8 it's way too late here too now.  

Good observation !

I can set up a DMD pool on groestlcoin.biz in about 15 minutes after I have a working wallet for Ubuntu 12.04 x64.
I spent about 2 hours trying to make it compile and it did eventually, but now it does not link :-)

I was planning to continue the linux wallet research, but looks like people have already found the solution?

And also, my Windows wallet that I used for solo mining on 4x R9 290 keeps crashing every time I find a block. So I'm afraid that even if I figure out how to build the Linux wallet, it'll be crashing and I'll get complaints from miners.

PS: As for stratum mining, it needs to be patched big time to make it work for Groestl algo. Took me about 2 weeks to figure everything out and test on my own. (BTW, I'm going to make this code public on 9th of May). So for now, I recommend everyone to use NOMP stratum. Hope this helps.

all the Groestl blocks found were invalid on the pool and your the first person I've seen say they've found a valid block.

So this leads to the conclusion that the Groestl algo is not the original from  will wait for devs to chime in on this. I'll dig thru the code a bit more see if I can fix the stratum to work with this version.
