Run Node Overview

Introduction

This guide covers running MAP Relay Chain (Atlas) nodes. Different node types serve different purposes in the network.

Node Types

Type Purpose Storage Use Case
Full Node Validate and relay Pruned state General participation
Archive Node Store full history Full state Historical queries
RPC Node Serve API requests Pruned/Full DApp backends
Validator Node Produce blocks Pruned state Network security
