I am rather busy this week with other stuff, and don't visit very often here.

But, as the Diamond team people were repeatedly telling me in this thread while I was combating it, "are your blocks foundation compatible?"

That is, do you send 0.05 DMD to the DMD contribution address with each block?
What are your wallet log files showing? That is, whatever the reason for the reject, it *is* listed there.

I hope to be able to help with more issues soon.

Hi dev,we should change it to a POS+POW mixed coin,like NRS
POS can help us keeping the coins in our wallet and it can help the network.
POW keeps the cost of mining and its price wont go down too much.

my idea is :
POW-6%->-10% weekly,
POS +4% weekly

in this way,we still have 6% reduce(maybe not such simple calculation but something like this),not changing too much.but I am sure the price will be as high as DRK!

so basical while -k groestlcoin need two special adaptions in miner software (block algo AND transaction hashing method) -k diamond need only groestl algo  activated and beside that stay standard

aby idea why GRS cpu miner dont work on DMD?

I dont care what anyone has agreed. we dont use the term groestlcoin we use the term MYRIAD-GROESTL since the beginning and even now. dont forget we were the firt groestl coin. so YOU should have obligation of stating groestlcoin groestl but we arent making you do it. So please shut up unless you have some actual facts to prove that we are lying.  Also i dont really care what you think is superior. We dont come in here normally and tell you, you are liars so i would certainly appreciate it if you didnt either

I'm using the game backing wallet currently FeSjdPY3D4Az94XD33hudKtRgim58uuq9G as a buffer for the transactions, but the rewards will be deducted form the faucet's address (which is showing a weird huge amount due to the way wallets handle the balances) FjTNDaXTMExn7WQpFQraV33XTzgaC7BJo3.

Thanks to the pointer given by the Legendarycoin team, i've implemented a new "kind" of faucet... Floppy faucet!

Be gentle plz....

Also, if anyonye is willing... Here's a personal "thank you" address FiWCJUzL1UPFza1PpF7oAcwSUUGohYQNSF

This is the first time I hear something like that.

these answer i have to leave for danbi
i dont work with code

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."}

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

   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);

PoS is irrelevant in this case. I disable it on the pool wallet, because it fills up the log file and also there is a risk to remain with negative balance when it stakes. Not good for pools.

I will do a clean diff with the current NOMP and my installation to see if there is any difference, but I don't believe there is -- after finding out what the "problem" is,  I just cloned it from github again.

Oh, I forgot this bit of the instructions. Must have (as usual) assumed it was obvious.

Thing is, GroestlCoin is actually deviating from the common standard, in that it (and few other new coins) is not using sha256d for the transaction hashes, but sha256 (single pass). To accomodate GroestlCoin, NOMP and sph-sgminer actually threat it as special case. In summary, it was never the new DMD wallet's fault that stratum mining did not work -- it was how that software assumed that when you said you want "groestl" you also said you want sha256 (single).

NOMP already has a setting to fix this, thanks to some discussion with the author. For coins that use any of (currently) keccak, blake, fugue and groestl -- you need to specify


in the coin definition.

By the way, the morale of this story is that the DMD team has been blamed without guilt on this subject.

with than miner u can use only 3345 port
i suggest to requiest that they add danbi's -diamond option to their official client

like i requested allready

https://bitcointalk.org/index.php?topic=475795.msg6684013#msg6684013

if more ask for it its more likly -diamond become part of official sph-miner

i think some pages back in this thread danbi posted a precompiled linux version and a link to his source if someone compiled it for windows i dont know

if nobody goes there, it won't happen... That's how the hashrate increase. It would be good that the hashrate get spread.

Anyhow, I spent a few hours there, didn't see any block. Went back to solo since an hour already 3 blocks... kinda strange
