8. Create Service

sudo tee /etc/systemd/system/emped.service > /dev/null <<EOF
[Unit]
Description=Empeiria node
After=network-online.target
[Service]
User=$USER
WorkingDirectory=$HOME/.empe-chain
ExecStart=$(which emped) start --home $HOME/.empe-chain
Restart=on-failure
RestartSec=5
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
EOF

9. Install Snapshot

cp $HOME/.empe-chain/data/priv_validator_state.json $HOME/.empe-chain/priv_validator_state.json.backup
rm -rf $HOME/.empe-chain/data
curl https://vault.astrostake.xyz/testnet/empeiria/empeiria_2025-06-08_snapshot.tar.lz4  | lz4 -dc - | tar -xf - -C $HOME/.empe-chain
mv $HOME/.empe-chain/priv_validator_state.json.backup $HOME/.empe-chain/data/priv_validator_state.json

10. Start Service

Useful Commands

Check blocks and peers

#!/bin/bash
rpc_port=$(grep -m 1 -oP '^laddr = "\K[^"]+' "$HOME/.empe-chain/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://empeiria-testnet-rpc.astrostake.xyz/status | jq -r '.result.sync_info.latest_block_height')

  if ! [[ "$local_height" =~ ^[0-9]+$ ]] || ! [[ "$network_height" =~ ^[0-9]+$ ]]; then
    echo -e "\033[1;31mError: Invalid block height data. Retrying...\033[0m"
    sleep 5
    continue
  fi

  blocks_left=$((network_height - local_height))
  echo -e "\033[1;33mNode Height:\033[1;34m $local_height\033[0m \033[1;33m| Network Height:\033[1;36m $network_height\033[0m \033[1;33m| Blocks Left:\033[1;31m $blocks_left\033[0m"

  sleep 5
