So far the orphan rates are much lower than even I expected. The transactions seem to be almost instantaneous, as well as block confirmations. There's a good number of trades and sending already which is good. Two pools reported 99%+ efficiency already.

The efficiency is really good and the network is super smooth because one of the algorithms is always going to find a block. I am mining it myself and plan to get more miners.
DGC has had really good transaction volume lately (millions) and it's helping to contribute to the miners.
