Networking

The network crate implements the P2P transport, discovery, and peer management used by sync and block propagation.

Core services

• NetworkService manages sessions and protocol handlers.

• Discovery maintains a node table and periodically refreshes peers.

• Handshake and session layers enforce protocol compatibility.

Configuration highlights

NetworkConfiguration includes:

• Listen/public addresses and UDP port.

• Bootnodes and reserved nodes.

• Peer limits and handshake limits.

• NAT and discovery settings.

• Throttling and IP filter controls.

Node typing and tagging

Peers advertise node_type tags (archive/full) to bias requests during sync, and the sync layer can choose preferred node types for block retrieval.
