System Requirements

This page outlines the infrastructure requirements for running an Ault full node. The specifications below reflect the configuration used in the official testnet partner guide. Running below these requirements may result in slow sync, unstable execution, or degraded performance.

Hardware Requirements

Component	Requirement	Notes
CPU	16 vCPU	Sustained performance required. Avoid burst instances.
Memory	64 GiB	Required for stable execution and state processing.
Storage	1 TiB	Must meet I/O requirements below.
Network	1 Gbps	Required for stable P2P connectivity and state sync.
OS	Ubuntu 24.04	The latest LTS release is recommended.

Storage & I/O Requirements

For AWS EBS:

Volume type: gp3
Provisioned IOPS: 8,000
Throughput: 500 MiB/s

Insufficient disk performance will directly impact node stability.

Operating System

Supported:

Ubuntu 24.04 LTS (the latest LTS release is recommended)

Set the timezone to UTC:

sudo timedatectl set-timezone UTC

System Dependencies

Install required packages before node setup:

sudo apt update && sudo apt upgrade -y

sudo apt install -y \
  curl wget git vim htop iotop sysstat net-tools jq \
  python3-pip build-essential software-properties-common \
  ca-certificates gnupg lsb-release bison ufw lz4

System Optimization

Network Optimization (BBR)

Enable TCP BBR congestion control:

sudo modprobe tcp_bbr

Apply sysctl tuning as provided in the setup guide.

Ulimits

Increase file descriptor and process limits:

* soft nofile 65535
* hard nofile 65535
* soft nproc 65535
* hard nproc 65535

Verify with:

ulimit -a

Network Ports

Port	Protocol	Purpose	Exposure
26656	TCP	Consensus P2P	Public (required for peering)
26657	TCP	Cosmos RPC	Optional
1317	TCP	REST API	Optional
9090	TCP	gRPC	Optional
8545	TCP	EVM JSON-RPC	Optional
8546	TCP	EVM WebSocket	Optional

After setup, ensure your P2P port is open and share your peer information in the following format: node-id@IP:PORT Retrieve your node ID with:

aultd comet show-node-id --home ~/.aultd
