Using Node Binary

Validator Nodes

1. Backup Files

Create a folder called "backup" in case it does not exist:

mkdir -p backup

Backup the harmony binary file:

cp harmony backup

2. Download Node Binary

Before we proceed to next steps we need to download the node binary first:

Mainnet

curl -LO https://harmony.one/binary && mv binary harmony && chmod +x harmony

Testnet

Check the node binary version that was downloaded:

./harmony -V

3. Restart Systemd Service

sudo service harmony restart

To check your node follow instructions on Checking A Node.
