State Sync

Cathing up to the latest block like a magic!

Reset blockchain data

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

Configure state sync

Configure state sync information
STATE_SYNC_RPC=https://union-testnet.rpc.nodex.one:443
STATE_SYNC_PEER=bbf8ef70a32c3248a30ab10b2bff399e73c6e03c@union-testnet.rpc.nodex.one:23156
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
