To start a Nucleus you need 25,000 Neutron in one input block.
The input must have 15 confirms, before trying to setup masternode.
After you have deposited exactly 25k neutron to your primary address, continue here.
Use console command:
Copy the outputted value and place that in neutron.conf :
Change other values to your liking and setup:
rpcuser=(any username)
rpcpassword=(any password)
server=1
daemon=1
listen=1
staking=0
port=9999
masternodeaddr=YourIPAddress:9999
masternode=1
masternodeprivkey=ValueGeneratedByGenKeyCommand
Notice: Make sure port 9999 is open via firewall to accept incoming connetions.
Restart wallet and type this command into the console:
* If you get errors, try starting wallet with masternode=0 before the genkey command.
Also, make sure the ip address is your own ip, not your public ip.
