### **Node Sync Status Checker**

```
#!/bin/bash
rpc_port=$(grep -m 1 -oP '^laddr = "\K[^"]+' "$HOME/.prysm/config/config.toml" | cut -d ':' -f 3)

while true; do
  local_height=$(curl -s localhost:$rpc_port/status | jq -r '.result.sync_info.latest_block_height')
  network_height=$(curl -s https://rpc-prysm.winnode.xyz/status | jq -r '.result.sync_info.latest_block_height')

  if ! [[ "$local_height" =~ ^[0-9]+$ ]] || ! [[ "$network_height" =~ ^[0-9]+$ ]]; then
    echo -e "\033[31mError: Invalid data. Retrying...\033[0m"
    sleep 5
    continue
  fi

  blocks_left=$((network_height - local_height))
  [ "$blocks_left" -lt 0 ] && blocks_left=0

  echo -e "\033[33mNode:\033[34m $local_height\033[0m \033[33m| Network:\033[36m $network_height\033[0m \033[33m| Left:\033[31m $blocks_left\033[0m"

  sleep 5
done
```

### **Create validator**

```
cd $HOME
# Create validator.json file
echo "{\"pubkey\":{\"@type\":\"/cosmos.crypto.ed25519.PubKey\",\"key\":\"$(prysmd comet show-validator | grep -Po '\"key\":\s*\"\K[^"]*')\"},
    \"amount\": \"1000000uprysm\",
    \"moniker\": \"test\",
    \"identity\": \"\",
    \"website\": \"\",
    \"security\": \"\",
    \"details\": \"\",
    \"commission-rate\": \"0.1\",
    \"commission-max-rate\": \"0.2\",
    \"commission-max-change-rate\": \"0.01\",
    \"min-self-delegation\": \"1\"
}" > validator.json
# Create a validator using the JSON configuration
prysmd tx staking create-validator validator.json \
    --from $WALLET \
    --chain-id prysm-devnet-1 \
	--gas auto --gas-adjustment 1.5 \
```
