Overview

Package lpp implements a peering.NetworkProvider based on the libp2p.

The set of known peers is managed in several places:

• TrustManager contains a registry of trusted peers and their pub keys. That's the main reference DB for the authentication. It is persistent.
• libp2p.Peerstore -- loaded with addresses and public keys based on the TrustManager. It is used by the libp2p for address resolution and protocol negotiation.
• In-memory copy of the trust DB in the netImpl struct (maps: peerNy*) with additional runtime data needed for a fast lookup of peers by their libp2p IDs, as well as for authentication etc.

The main identification of a peer is its public key. The address (peeringURL) may change over time (because of NAT, and similar reasons).

Functions

func NewNetworkProvider

func NewNetworkProvider(
	myPeeringURL string,
	port int,
	nodeKeyPair *cryptolib.KeyPair,
	trusted peering.TrustedNetworkManager,
	log *logger.Logger,
) (peering.NetworkProvider, peering.TrustedNetworkManager, error)

NewNetworkProvider is a constructor for the TCP based peering network implementation.
