Additional info.

GeertJohan has developped a simulator for testing DGW3. See Github below. Now to test different algo's and bigger hashrate swings and pool jumps, the diff. simulator is further being developped, so in the end there will be the perfect algo for Guldencoin.

If it is for a paid job, I don't know. Help is welcome in any way to join this simulator program for the good of crypto in general also.

As GeertJohanh is saying in Github:
