I've moved everything back to BTCG where I make less than Slush but I'm informed at all times and issues are not only fixed but communicated as well.
You'll end up making more on Guild. 1% fee difference doesn't make up for paid orphans and NMC merged mining. Assuming you're on PPLNS (which I would certainly hope you are).
Been curious but haven't looked into it yet... Can anyone explain to me NMC merged mining? Is this a scrypt coin for people without ASIC so they can still produce in a pool?
NMC was the first altcoin, and it is a SHA256 coin. It was not designed as a currency, it's main use being a decentralized DNS system. However, most people just use it to trade for BTC, and in 2011 people would hop on/off of NMC based on difficulty/profitability. It was hurting BTC (big loss of hash rate), and ended up nearly killing NMC when the difficulty was driven up so high and the price so low that it was going to take *months* before the difficulty would adjust down again.
To fix that problem, the NMC devs designed a way for a coin to piggyback on the hash rate of another coin, by using the coinbase of the primary coin to embed a block header for the alternate chain, and allowing a way to similarly embed information in the primary chain into the namecoin coinbase to link the two together. It proves that work was done to solve the NMC block at the same time as the BTC block. In effect, NMC is now a byproduct of BTC mining if the pool is setup to do it. It is created at no extra cost to the miner, and only a marginal extra cost on the server.
