StateSync

Stop the service and reset the data

sudo systemctl stop empowerd
cp $HOME/.empowerchain/data/priv_validator_state.json $HOME/.empowerchain/priv_validator_state.json.backup
empowerd tendermint unsafe-reset-all --home $HOME/.empowerchain --keep-addr-book

Get and configure the state sync information

STATE_SYNC_RPC=https://empower.rpc.moonbridge.team:443
LATEST_HEIGHT=$(curl -s $STATE_SYNC_RPC/block | jq -r .result.block.header.height)
SYNC_BLOCK_HEIGHT=$(($LATEST_HEIGHT - 1000))
SYNC_BLOCK_HASH=$(curl -s "$STATE_SYNC_RPC/block?height=$SYNC_BLOCK_HEIGHT" | jq -r .result.block_id.hash)


sed -i \
  -e "s|^enable *=.*|enable = true|" \
  -e "s|^rpc_servers *=.*|rpc_servers = \"$STATE_SYNC_RPC,$STATE_SYNC_RPC\"|" \
  -e "s|^trust_height *=.*|trust_height = $SYNC_BLOCK_HEIGHT|" \
  -e "s|^trust_hash *=.*|trust_hash = \"$SYNC_BLOCK_HASH\"|" \
  $HOME/.empowerchain/config/config.toml


mv $HOME/.empowerchain/priv_validator_state.json.backup $HOME/.empowerchain/data/priv_validator_state.json

Download wasm

curl -o - -L https://snapshots.moonbridge.team/mainnet/empower/wasm_latest.tar.lz4 | lz4 -dc - | tar -x -C $HOME/.empowerchain

Start the service and check the log

sudo systemctl start empowerd && sudo journalctl -u empowerd -f --no-hostname -o cat

Disable synchronization with StateSync

sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1false|" $HOME/.empowerchain/config/config.toml
sudo systemctl restart empowerd && sudo journalctl -u empowerd -f --no-hostname -o cat
