Bitcoin Hush is actually a Komodo Asset chain, so we need to download and compile that code, which will allow us to connect to the BTCH network. We must tell it a node to connect to that knows about the BTCH asset chain.
BTCH uses RPC port 10161 and a P2P port of 10160, you might need to allow them in your firewall.
