i have a problem, sended some dmd from pool http://dmdpool.digsys.bg/
tx info should be here http://www.diamondblocks.info/tx/09765220f7200c0f6a15be7f6bc1d969a2723302e3311d43a341bd233eacc1d4
but looks like it offline.
after 2 hours, coins still didnt come to crypsy

whats happened?

I had a look here:

https://github.com/danbi/sph-sgminer/commit/a9cd797df5d7917d4de7ab06727b695b0b20a3d1

It seems there is no difference between diamond and groestlcoin, what am I missing?

groestlcoin did choose using regarding transactions sha256 instead of sha256d which most coins uses
diamond did stay on the established standard of sha256d

at solomining this doesnt matter because transactions are handled inside wallet

at stratum mining block have to be prepared by miner + stratum the right way to be accepted by the wallet

could you point me to the related change in the commits?
many thanks!

whats happened? 

http://dmdchain.cyber.si/ is the block explorer as stated on first page of this ANN thread
website is going through a relaunch info's there not up to date

for cryptsy deposit and withdrawal troubles please get in touch with their support
it seems they still didn't finish their wallet upgrade

This is the most important code:

   if (gpus[0].kernel == KL_FUGUECOIN || gpus[0].kernel == KL_GROESTLCOIN || gpus[0].kernel == KL_TWECOIN)
      sha256(pool->coinbase, pool->swork.cb_len, merkle_root);
   else
      gen_hash(pool->coinbase, merkle_root, pool->swork.cb_len);

As you can see, Groestlcoin will go into sha256(), while Diamondcoin will go into gen_hash()

Correct. It took me a lot of time to realize the solution is *that* simple, but I eventually went for adding the full support for a new kernel, 'diamond'. The reason is that at some future time GroestlCoin might change something and we will end up with non functional miner by depending on their algorithm/special case.
I also skimmed by not cloning the groestl function processing as well, but will likely do it at later date (add diamond specific hasing functions), so again, if GroestlCoin spec is changed, we don't suffer.

Since all these changes are rather trivial, I would expect other mining software to adapt. I modified only this miner, because it's what I use. If theer is interest, I can look at the code of other miners as well. Just don't ask me to compile on Windows!

thanks danbi, srcxxx and cryptonit for the information, very helpful! :-)

I compiled windows sgminer from the source. Tested and works with stratum with diamond kernel!
Enjoy!]

Any DMD tips can be sent here: daVzPCTzZFytFGmjHERfzXiEpQYevnwxpq  

Change your sgminer.conf

"kernel" : "groelstcoin"
to
 "kernel" : "diamond"

If share difficulty too high (16) add:
"difficulty-multiplier" : "0.00390625"

Doesn't work for me. Says "waiting for work to be available from pools" for some time and then that no pools can connect. Tried 3 times. Pool URL is correct, internet works ok. Perhaps missing some library/dll ?

Thanks

Hi!

Is there an updated daemon for unix?

I've been troubleshooting why my pool doesn't work and here's what I see:

2014-05-12 12:16:50 [Pool]   [diamondcoin] (Thread 1) rpc error with daemon instance 0 when submitting block with submitblock {"code":-2,"message":"Safe mode: WARNING: Invalid checkpoint found! Displayed transactions may not be correct! You may need to upgrade, or notify developers."}

Thanks!

Update: recompiled version 2.0.1 from source. Hopefully, it'll fix all problems.

[djm34]

For people interested, you can find also a modified version of ccminer (nvidia card) working with DMD stratum.
https://bitcointalk.org/index.php?topic=167229.msg6695779#msg6695779

The modification is similar to the one applied to the sgminer.

btw: Can we know which pool are working or not ?
What about Dwarfpool ? may-be Atrides should be recontacted so he can implement the mod to his pool

It only works on danbi's pool I think: http://dmdpool.digsys.bg/index.php
I am currently mining there with stratum. Remember to use stratum port 3333 instead of 3345.

So it's stratum+tcp://dmdpool.digsys.bg:3333 ?
Cause I can't with it on Xubuntu

Are you sure it actually generates accepted shares? For me it does run with stratum+tcp and port 3333, but I don't get any accepted shares...

I'm on ubuntu and it's working with the latest miner from danbi (git clone, autogen, configure, make)

[johndec2]

Did you change the -k parameter in your bat file from groestlcoin to diamond?  Caught me out at first.  Mining like crazy but no accepts.  Changed it and all good!

I have kernel groestlcoin in sgminer.conf.
Must I change in diamond?

[johndec2]

If you are using Jarski's windows stratum miner, yes.

Yes you should use diamond kernel.
"kernel" : "diamond"
Also if you have share difficulty 16, which is too high, use this:
"difficulty-multiplier" : "0.00390625"

Happy mining!
