Hi andr0x,

Thanks for your kind words.

First of all do you have enough hash-power to mine block alone? I personally prefer and suggest guys to first run with testnet daemon, so that you can make sure everything is working okay (in terms of mining & block submissions)

Other then that which version do you use? A release version or latest development tree?

Would be nice to see your debug.log file for Digibyte (https://github.com/CoiniumServ/CoiniumServ/wiki/How-to-ask-questions-and-report-bugs%3F) so I can check for any outstanding errors.

For the groestl part, does myriad-coin or digibyte-groestl use a specific groestl implementation? If not we already have the groestl implementation in https://github.com/CoiniumServ/CoiniumServ/blob/develop/src/CoiniumServ/Cryptology/Algorithms/Groestl.cs (which though is not tested).

You can give a try within a digibyte-groestl testnet for example.
