# 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.

## Key source files

* `crates/network/src/lib.rs`
* `crates/network/src/service.rs`
* `crates/network/src/discovery.rs`
* `crates/mazzecore/core/src/sync/message/status.rs`
