Validator Node

A blockchain validator is a node on a blockchain network that is responsible for verifying transactions on the network. — Validators are an essential component of a blockchain network, helping to ensure its security, accuracy, and reliability

How To Become a Elysium Validator

  • Please make sure your machine meets the minimum requirements.
  • Subkey is a utility provided by substrate to generate new accounts and network keys.
  • You can build it on your machine or can download it for available OS from this link.
  • Once you have setup the subkey go to the downloaded folder and Run the command from command line to generate peer id and account keys.
subkey generate-node-key

This command is used to generate random public and private keys for peer-to-peer (libp2p) communication between Elysium nodes. The public key is the peer identifier that is used in chain specification files or as a command-line argument to identify a node participating in the blockchain network. In most cases, you run this command with a command-line option to save the private key to a file. The generated output will be like:


Peer ID


Node Key


Generate a new account key

To generate a new key pair that uses the sr25519 signature scheme, run the following command:

subkey generate

The command generates keys and displays output similar to the following:

Public key (hex): 0xb6a8b4b6bf796991065035093d3265e314c3fe89e75ccb623985e57b0c2e0c30
Account ID: 0xb6a8b4b6bf796991065035093d3265e314c3fe89e75ccb623985e57b0c2e0c30
Public key (SS58): 5GCCgshTQCfGkXy6kAkFDW1TZXAdsbCNZJ9Uz2c7ViBnwcVg
SS58 Address: 5GCCgshTQCfGkXy6kAkFDW1TZXAdsbCNZJ9Uz2c7ViBnwcVg

You now have the Sr25519 key for producing blocks using aura for one node. In this example, the Sr25519 public key for the account is 5GCCgshTQCfGkXy6kAkFDW1TZXAdsbCNZJ9Uz2c7ViBnwcVg.

The easiest way using Docker

The easiest/faster option to run elysium in Docker is to use the latest release images. These are small images that use the latest official release of the elysium binary, pulled from our package repository.

docker run --rm -it vaival/elysium:latest --chain local --name "elysium"


Once you are done experimenting and picking the best node name :) you can start elysium node. Make sure that you set the ownership of your local directory to the current user.

# 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

Using Docker compose

You can use the following docker-compose.yml file:

version: '3'

container_name: elysium-node
image: vaival/elysium:latest
- 30333:30333 # p2p port
- 9933:9933 # rpc port
- 9944:9944 # ws port
- 9615:9615 # promethus port
- ./elysium-data:/data
command: [
"--name", "elysium-node",
"--rpc-cors", "all",
"--node-key", "d1f036e7b462067f87f39342f4e3cfa5dbea4eac1fe5cbad269aa14abaf418c4",
"--chain", "./elysiumSpecRaw.json"
"--bootnodes", "/ip4/{boot-node-ip}/tcp/30333/p2p/12D3KooWGRwF66g11uFWzRHHcfj5gehnFj1oXRHdwnJ1dGa2Nai3"

As Elysium is a private chain, you need to contact with elysium team to allow your node to participate as validator and to earn reward.
