To set up your own Ghostnode, you need to meet the following requirements:
A VPS with at least 1GB of RAM
Create a new G address in your wallet by typing getnewaddress GN1 ghostnode into your wallet console. Proceed to send exactly 40000 NIX there (do not tick subtract fee from amount in the sending screen).
Afterwards, enter ghostnode outputs into your wallet to get the output needed for all other steps.
