SCORE_HEADER =

HTTP header we add to each HTTP request, in order to inform the other node about the score. If the score is big enough, the remote node will add us to its list of remote nodes.

'X-Zold-Score'
VERSION_HEADER =

HTTP header we add, in order to inform the node about our version. This is done mostly in order to let the other node reboot itself, if the version is higher.

'X-Zold-Version'
NETWORK_HEADER =

HTTP header we add, in order to inform the node about our network. This is done in order to isolate test networks from production one.

'X-Zold-Network'
