Package node is the main entry point, where the Node struct, which represents a full node, is defined.

    Adding new p2p.Reactor(s)

    To add a new p2p.Reactor, use the CustomReactors option:

    node, err := NewNode(
    		CustomReactors(map[string]p2p.Reactor{"CUSTOM": customReactor}),

    Replacing existing p2p.Reactor(s)

    To replace the built-in p2p.Reactor, use the CustomReactors option:

    node, err := NewNode(
    		CustomReactors(map[string]p2p.Reactor{"BLOCKCHAIN": customBlockchainReactor}),

    The list of existing reactors can be found in CustomReactors documentation.
