# Overview

> Base protocol specifications, core primitives, and network systems.

Technical specifications for how Base works at the chain level. Core Primitives covers what developers interact with directly — tokens, accounts, bridging, fees, and transactions. Network Systems covers protocol internals — the batcher, consensus, execution, and proof system.
