StateSync

Stop the service and reset the data

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

Get and configure the state sync information

STATE_SYNC_RPC=https://prysm-test.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|" \

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

Start the service and check the log

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

Disable synchronization with StateSync

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