State Sync

Instructions

Stop the service and reset the data

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

Get and configure the state sync information

STATE_SYNC_RPC=https://union-testnet.rpc.liveraven.net:443
STATE_SYNC_PEER=8978a749557b044feb7ea659af71f09a561470de@union-testnet.rpc.liveraven.net:30656
LATEST_HEIGHT=$(curl -s $STATE_SYNC_RPC/block | jq -r .result.block.header.height)
SYNC_BLOCK_HEIGHT=$(($LATEST_HEIGHT - 2000))
SYNC_BLOCK_HASH=$(curl -s "$STATE_SYNC_RPC/block?height=$SYNC_BLOCK_HEIGHT" | jq -r .result.block_id.hash)

echo $LATEST_HEIGHT $SYNC_BLOCK_HEIGHT $SYNC_BLOCK_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\"|" \
    -e "s|^persistent_peers *=.*|persistent_peers = \"$STATE_SYNC_PEER\"|" \
    $HOME/.union/config/config.toml

mkdir -p $HOME/.union/data && mv $HOME/.union/priv_validator_state.json.backup $HOME/.union/data/priv_validator_state.json

Restart the service and check the log

sudo systemctl start uniond && sudo journalctl -u uniond -fn 100 -o cat
