# Running Nodes

This section explains how to build, run, and maintain Cronos nodes across Mainnet, Testnet, and Devnet. It covers key areas such as compiling `cronosd`, configuring validators and full nodes, managing upgrades, and optimizing synchronization with tools like snapshots, local state sync, VersionDB and MemlAVL. The aim is to provide node operators with clear guidance to keep their infrastructure stable and efficient.

Whether you’re launching a validator, hosting infrastructure, or contributing to the network, this page walks you through everything from initial setup to advanced optimizations.
