/**
 * The architecture of the network looks like so:
 * - core:
 *   - INetworkCore - This interface encapsulates all functionality from BaseNetwork, its meant to act as an wrapper that makes multiple implementations more simple
 *   - NetworkCore - This _implementation_ contains all libp2p and dependent modules
 *   - WorkerNetworkCore - This _implementation_ wraps a NetworkCore in a Worker thread
 * - INetwork - This interface extends INetworkCore and crucially allows for a connection to the BeaconChain module.
