Types

type Config 

type Config struct {
	// TrustedHash is the Block/Header hash that Nodes use as starting point for header synchronization.
	// Only affects the node once on initial sync.
	TrustedHash string
	// TrustedPeers are the peers we trust to fetch headers from.
	// Note: The trusted does *not* imply Headers are not verified, but trusted as reliable to fetch headers
	// at any moment.
	TrustedPeers []string
}

func DefaultConfig 

func DefaultConfig() Config

TODO(@Wondertan): We need to hardcode trustedHash hash and one bootstrap peer as trusted.
