For instructions, go here, but ignore everything at the beginning about setting up the Linux instance and building the application (this isn't applicable to you):
http://www.chaincoin.org/Setting%20up%20a%20Chaincoin%20Masternode%20-%20draft%20v.04.pdf
Send exactly 1,000 coins to your wallet in a single transaction (no less and no more, I'm serious, account for the fee if you are sending from Cryptopia send 1000.0001 for example). The 1,000 CHC must be in a SINGLE TRANSACTION in your wallet, or it won't work.
Extract the private key corresponding to the Chaincoin address that received the 1,000 CHC and put that in the masternodeprivkey property of the chaincoin.conf file. It should look something like this:
rpcpassword=
server=1
listen=1
masternode=1
masternodeprivkey=
masternodeaddr=
Once this is done, restart Chaincoin-QT, let it initialize, then go to debug console and enter:
masternode start
It is a good idea to look carefully at information in the debug.log file (same folder as chaincoin.conf). Look carefully for the word capable in debug.log, because when your masternode receives 15 confirmations, you'll see that message, indicating that your node is masternode-capable.
Next, the acid test though is whether you see your node in the list when you issue this command:
masternode list
If you see your IP address in the list with the word "ENABLED" you're probably good-to-go.
Note: you must open ports 8333 and 11994 through your router to your PC for this to work. If those ports are not open, no dice. Also, you must leave your machine on 24X7.
Thank you!
