# State sync

### Stop the service and reset the data

```
sudo systemctl stop ojo.service
cp $HOME/.ojo/data/priv_validator_state.json $HOME/.ojo/priv_validator_state.json.backup
ojod tendermint unsafe-reset-all --keep-addr-book --home $HOME/.ojo
```

### Get and configure the state sync information

```
STATE_SYNC_RPC=https://ojo-testnet.rpc.kjnodes.com:443
STATE_SYNC_PEER=d5519e378247dfb61dfe90652d1fe3e2b3005a5b@ojo-testnet.rpc.kjnodes.com:15056
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\"|" \
  -e "s|^persistent_peers *=.*|persistent_peers = \"$STATE_SYNC_PEER\"|" \
  $HOME/.ojo/config/config.toml
```

```
mv $HOME/.ojo/priv_validator_state.json.backup $HOME/.ojo/data/priv_validator_state.json
```

### Restart the service and check the log

```
sudo systemctl start ojo.service && sudo journalctl -u ojo.service -f --no-hostname -o cat
```
