This will be interesting to watch.
I was contacted by a member of a group that have been working on a CPU only coin for quite some time. Which is why I put the CPU -only project on hold. (I haven't talked to them in a bit , been a hell of a couple of weeks).
From what I read and learned, the successful design of a coin of this nature is a bit complex, and there were still a few hurdles to overcome.
Dammit, now I have to switch the CPUs in my mining rigs, and I should have bought the 8 core instead of the 6 core for my main PC...
As for the explorer, one thing learned over the past few days, is that I have to be careful about what I add especially with breakneck speed coins are being released. Most of the issues with the new server (and the three new coins) have been due to attacks on the CHNcoin explorer.
