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

Quick Start

1. Install Atlas

# Clone repository
git clone https://github.com/mapprotocol/atlas.git
cd atlas

# Build
make atlas

# Verify installation
./build/bin/atlas version

2. Initialize Node

# Create data directory
mkdir -p ~/.atlas

# Initialize with genesis
./build/bin/atlas --datadir ~/.atlas init genesis.json

3. Start Node

# Start full node
./build/bin/atlas --datadir ~/.atlas \
  --networkid 22776 \
  --syncmode full
