Run a Node on Elysium

Running a full node on a Elysium network allows you to connect to the network, sync with a bootnode, obtain local access to RPC endpoints, author blocks on the chain, and more.

There are two types of deployments of Elysium, including the Atlantis (Testnet).

Requirements

The minimum specs recommended to run a node are shown in the following table. For our MainNet deployments, disk requirements will be higher as the network grows.

Component	Requirement
CPU	8 Cores (Fastest per core speed)
RAM	16 GB
SSD	1 TB (recommended)
Firewall	P2P port must be open to incoming traffic

Running Ports

The only ports that need to be open for incoming traffic are those designated for P2P. Validator must not have RPC or WS ports opened.

Default Ports for a chain Full-Node

Description	Port
P2P	30333 (TCP)
RPC	9933
WS	9944
Prometheus	9616

Installation with Docker

Elysium node can be spun up quickly using Docker. For more information on installing Docker, please visit this page. At the time of writing, the Docker version used was 24.0.1. When connecting to Elysium, it will take a few hours to completely sync the chain data. Make sure that your system meets the requirements.

Create a local directory to store the chain data:

Network	Command
Elysium	mkdir /var/lib/elysium-data
Atlantis (Testnet)	mkdir /var/lib/elysium-testnet-data

Next, make sure you set the ownership and permissions accordingly for the local directory that stores the chain data. In this case, set the necessary permissions either for a specific or current user (replace DOCKER_USER for the actual user that will run the docker command):

Elysium

# chown to a specific user
chown DOCKER_USER /var/lib/elysium-data

# chown to current user
sudo chown -R $(id -u):$(id -g) /var/lib/elysium-data

Atlantis (Testnet)

# chown to a specific user
chown DOCKER_USER /var/lib/elysium-testnet-data

# chown to current user
sudo chown -R $(id -u):$(id -g) /var/lib/elysium-testnet-data

Now, execute the docker run command. If you are setting up a validator node, make sure to follow the code snippets for Validator.

Dev Node Setup

Create a file name as docker-compose.yml and add below code:

version: '3'

services:
  elysium-dev-node:
    container_name: elysium-dev-node
    image: vaival/elysium-testnet:latest
    ports:
      - 30333:30333 # p2p port
      - 9933:9933 # rpc port
      - 9944:9944 # ws port
      - 9615:9615 # promethus port
    volumes:
      - ./elysium-testnet-data:/data
    command: [
      "--name", "elysium-dev-node",
      "--dev"
      "--ws-external",
      "--rpc-external",
      "--rpc-cors", "all"
    ]

After saving the file run the below code:

docker compose up

Docker engine will start the node, you can connect it locally by using below urls:

Local RPC Access:

https://127.0.0.1:9933

Local Websocket Access:

ws://127.0.0.1:9944
