Configure the Validator

Download the validator configuration template:

wget -O ~/sui/validator-template.yaml https://github.com/MystenLabs/sui/raw/main/crates/sui-config/data/validator-template.yaml

Edit the configuration: Open the validator-template.yaml file and configure data paths, for example:

db-path: "/home/username/sui/data/db"
network-address: "/ip4/0.0.0.0/tcp/8080"
consensus-address: "/ip4/0.0.0.0/tcp/9000"
p2p-config: "/home/username/sui/data/p2p"
genesis-file: "/home/username/sui/data/genesis.blob"

Download the genesis file:

wget -O ~/sui/data/genesis.blob https://github.com/MystenLabs/sui-genesis/raw/main/mainnet/genesis.blob

Generate validator keys:

sui keytool generate --key-file ~/sui/validator.key

Initialize validator configuration:

sui genesis --validator-template ~/sui/validator-template.yaml --working-dir ~/sui/data --validator-key ~/sui/validator.key

---

Start the Validator

Run the validator manually:

sui-node --config-path ~/sui/data/fullnode-template.yaml

Set up a systemd service for automated startup:

sudo nano /etc/systemd/system/sui-validator.service

Add the following content:

[Unit]
Description=Sui Validator
After=network.target

[Service]
User=your_username
ExecStart=/usr/local/bin/sui-node --config-path /home/your_username/sui/data/fullnode-template.yaml
Restart=on-failure
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target

Enable and start the service:

sudo systemctl enable sui-validator
sudo systemctl start sui-validator

---

Join the Validator Network

Register as a validator:

• Ensure your wallet (keys generated earlier) has sufficient SUI tokens.

• Use the Sui CLI to deposit the stake:

  sui client switch --address <YOUR_ADDRESS>
  sui client stake <AMOUNT_OF_TOKENS>

Confirm registration: Once the stake is deposited, your node will become a validator in the next epoch.
