I setup a p2pool for quarkcoin, because it seems like most of them are currently are unstable, and I would like to have a stable one that people can depend on. The server is extremely reliable due to the fact that it has ddos protection, and plenty of resources at its disposal.

To start mining simply change the bat file to use your quark wallet, and you're good to go! Enjoy!
