Reset blockchain data

Make sure backup your priv_validator_state.json before reset

sudo systemctl stop og
cp $HOME/.0gchain/data/priv_validator_state.json $HOME/.0gchain/priv_validator_state.json.backup
0gchaind tendermint unsafe-reset-all --keep-addr-book --home $HOME/.0gchain

Configure State Sync

SNAP_RPC="https://rpc-0g.sebatian.org"
LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$((LATEST_HEIGHT - 1000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)
echo $LATEST_HEIGHT $BLOCK_HEIGHT $TRUST_HASH

sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \

s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC\"| ; \

Backup state data

Return state file to the previous location

mv $HOME/.0gchain/priv_validator_state.json.backup $HOME/.0gchain/data/priv_validator_state.json

Restart your nodes after perform a state sync

sudo systemctl start og && sudo journalctl -fu og -o cat
