Ready for the Helixcoin launch?
Yep, though they haven't released any nodes to use for "addnode=IP" configs

One is built into the QT-wallet I believe. The rest one are probably discovered via P2P. If I got all my altcoin wallet finangles right. Its worse when the wallet is showing "No block source found." Let's hope the authors will release the wallet before difficulty is 100K ><
