Validator Node Installation

Running a validator node for the 0G-Galileo-Testnet in the 0G ecosystem means actively participating in the network’s security and consensus through the Proof-of-Stake (PoS) mechanism. As a validator, you’ll validate transactions, propose new blocks, and earn rewards for your contribution to the network’s integrity and decentralization.

Init Iliad node

story init --network iliad --moniker "Your_moniker_name"

Create story-geth service file

sudo tee /etc/systemd/system/story-geth.service > /dev/null <<EOF
[Unit]
Description=Story Geth Client
After=network.target

[Service]
User=root
ExecStart=/root/go/bin/story-geth --iliad --syncmode full
Restart=on-failure
RestartSec=3
LimitNOFILE=4096

[Install]
WantedBy=multi-user.target
EOF

Create story service file

sudo tee /etc/systemd/system/story.service > /dev/null <<EOF
[Unit]
Description=Story Consensus Client
After=network.target

[Service]
User=root
ExecStart=/root/go/bin/story run

Reload and start story-geth

sudo systemctl daemon-reload && \
sudo systemctl start story-geth && \
sudo systemctl enable story-geth && \
sudo systemctl status story-geth

Reload and start story

sudo systemctl daemon-reload && \
sudo systemctl start story && \
sudo systemctl enable story && \
sudo systemctl status story

Check logs

sudo journalctl -u story-geth -f -o cat

Wait a minute for connect peers

sudo journalctl -u story -f -o cat

###Check sync status

curl localhost:26657/status | jq

Waiting for your nodecatching_up is false you can create validator.

Create validator

Export validator Public Key & Private key

By default, when you run story init a validator key is created for you. To view your validator key, run the following command:

story validator export

In addition, if you want to export the derived EVM private key of your validator into the default data config directory, please run the following:

story validator export --export-evm-key

*Important: Please keep your private key in a safe place Your EVM Private Key saved to: /root/.story/story/config/private_key.txt Note that to participate in consensus, at least 1 IP must be staked (equivalent to 1000000000000000000 wei)! Faucet link: https://faucet.story.foundation/

Create validator

story validator create --stake 1000000000000000000 --private-key "your_private_key"

Backup the validator key:

• File location: /root/.story/story/config/priv_validator_key.json
• Copy this file to your local machine.
• Store it carefully; this is the most crucial key for your validator.

Validator Staking

story validator stake \
   --validator-pubkey "VALIDATOR_PUB_KEY_IN_BASE64" \
   --stake 1000000000000000000 \
   --private-key xxxxxxxxxxxxxx

Replace VALIDATOR_PUB_KEY_IN_BASE64 Amount: 1000000000000000000=1 IP Token

###Check your Validator on Explorer

• Get your validator info:

curl -s localhost:26657/status | jq -r '.result.validator_info'

Result: { "address": "D6F92FD7D0460AA9E4CF4D299FE479E93395DCF3", "pub_key": { "type": "tendermint/PubKeySecp256k1", "value": "A+46wEmBx5QQscNOKhmJgaAQjdr85s1OzvNimMiaysp3" }, "voting_power": "15000" }

• Paste HEX Validator Address: D6F92FD7D0460AA9E4CF4D299FE479E93395DCF3 to search https://testnet.story.explorers.guru/
