Berachain bArtio Testnet Full Node Deployment Guide

Architecture & Protocol Overview

Execution topology, consensus mechanics, and operational assumptions.

Berachain uses the Polaris EVM modular execution environment on top of CometBFT consensus. This guide covers deploying a full synchronized node on the bArtio testnet.

Pre-Flight System Check (Ubuntu 22.04 / 24.04 LTS)

PRE-FLIGHT

Run this single diagnostics command on your host before beginning the installation to ensure you have sufficient compute, disk headroom, and proper privileges:

preflight-check.sh

lscpu | grep "Model name\|CPU(s):"
free -h
df -h /
uname -a

Step 1 of 1

Hardware Benchmark Verification

Verify your server meets the 8-core CPU and high NVMe IOPS threshold before initializing the state database.

bash ~ root@validator

lscpu | grep "CPU(s):"
free -h
df -h /

Expected Stdout / Terminal VerificationSTDOUT STREAM

CPU(s): 8 or 16
Mem: 32Gi

How to Verify Step Success:Ensure available disk space on root mount is at least 800GB.

Network Port Matrix & UFW Firewall Hardening

Configure your server firewall so that P2P gossip ports are accessible to network peers while internal RPC and Engine APIs remain strictly protected from public port scanners.

Port / Protocol	Interface	Access Level	UFW Command
22 / TCP	SSH Management	Restricted / VPN	sudo ufw allow 22/tcp
P2P Peer Ports	Gossip & Block Sampling	Public (0.0.0.0/0)	sudo ufw allow 26656/tcp
RPC / REST / API	Node Query & Transactions	Localhost Only (127.0.0.1)	(Do not open publicly)
