package node

import "github.com/tendermint/tendermint/node"

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.
