Information of a remote node.

A remote node connects to the local node via the P2P network. It is often called a peer.

Fields

version: String

The remote node version.

node_id: String

The remote node ID which is derived from its P2P private key.

addresses: Vec<NodeAddress>

The remote node addresses.

is_outbound: bool

Whether this is an outbound remote node.

If the connection is established by the local node, is_outbound is true.

connected_duration: Uint64

Elapsed time in seconds since the remote node is connected.

last_ping_duration: Option<Uint64>

Elapsed time in milliseconds since receiving the ping response from this remote node.

Null means no ping responses have been received yet.

sync_state: Option<PeerSyncState>

Chain synchronization state.

Null means chain sync has not started with this remote node yet.

protocols: Vec<RemoteNodeProtocol>

Active protocols.

CKB uses Tentacle multiplexed network framework. Multiple protocols are running simultaneously in the connection.
