sed -i 's|^prometheus *=.*|prometheus = true|' $HOME/.pellcored/config/config.toml

10. Create service file

sudo tee /etc/systemd/system/pellcored.service > /dev/null <<EOF
[Unit]
Description=Pell-network-testnet
After=network-online.target

[Service]
User=$USER
Environment="LD_LIBRARY_PATH=/root/.pellcored/lib"
ExecStart=$(which pellcored) start --chain-id ignite_186-1 --home $HOME/.pellcored
Restart=on-failure
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

Download snapshot

cd $HOME
rm -f pell_snapshot.*
aria2c -x 16 -s 16 -k 1M https://pell.j-node.net/pell_snapshot.lz4

pellcored tendermint unsafe-reset-all --home $HOME/.pellcored
lz4 -dc pell_snapshot.lz4 | pv | tar -xf - -C $HOME/.pellcored

Enable service and start node

sudo systemctl daemon-reload
sudo systemctl enable pellcored
sudo systemctl start pellcored && sudo journalctl -fu pellcored -o cat

# Check status

pellcored query status | jq

pellcored query status | jq '{ latest_block_height: .sync_info.latest_block_height, catching_up: .sync_info.catching_up }'

# Block sync left:

while true; do
 local_height=$(pellcored query status | jq -r '.sync_info.latest_block_height');
  network_height=$(curl -s https://rpc-pell.j-node.net/status | jq -r '.result.sync_info.latest_block_height')
  blocks_left=$((network_height - local_height));

  echo -e "\033[1;38mYour node height:\033[0m \033[1;34m$local_height\033[0m | \033[1;35mNetwork height:\033[0m \033[1;36m$network_height\033[0m | \033[1;29mBlocks left:\033[0m \033[1;31m$blocks_left\033[0m";
  sleep 5;
done

Note

You can see your node’s latsest_block_height (Or you can check catching_up is false) If the block height is set, you can create validator.

12. Create validator

Add new wallet

pellcored keys add "wallet_name"

Recover wallet

pellcored keys add "wallet_name" --recover

Caution

Don’t forget to save the mnemonic

Pell explorer

Pell Scan

Check Balance

pellcored q bank balances $(pellcored keys show "wallet_name" -a)

Create validator

• Create validator.json file

cd $HOME
echo "{
    \"pubkey\":{
        \"@type\":\"/cosmos.crypto.ed25519.PubKey\",
        \"key\":\"$(pellcored query status | jq -r '.validator_info.pub_key.value')\"
    },
    \"amount\": \"1pell\",
    \"moniker\": \"YOUR_NODE_NAME\",
    \"identity\": \"YOUR_KEY_BASE\",
    \"website\": \"YOUR_WEBSITE\",
    \"security\": \"YOUR_CONTACT\",
    \"details\": \"I love blockchain 🚀\",
    \"commission-rate\": \"0.05\",
    \"commission-max-rate\": \"0.2\",
    \"commission-max-change-rate\": \"0.01\",
    \"min-self-delegation\": \"1\"
}" > validator.json

• Create a validator with .json file

pellcored tx staking create-validator validator.json \
    --from "wallet_name" \
    --chain-id ignite_186-1 \
    --gas auto \
    --gas-adjustment 1.5 \
    --gas-prices 33apell \
    -y

• Delegate to your validator:

pellcored tx staking delegate $(pellcored keys show "wallet_name" --bech val -a) 1pell \
--from "wallet_name" \
--chain-id ignite_186-1 \
--gas auto \
--gas-adjustment 1.5 \
--gas-prices 50apell \
-y

Caution

Backup the validator key:

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