# State Sync

### **Stop the service and reset the data**

```bash
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**

```bash
STATE_SYNC_RPC=https://union-testnet.rpc.liveraven.net:443
STATE_SYNC_PEER=b25b49f8e27607ebf62158ee110559a4fa2adbd1@23.88.5.169:30656
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**

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

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://services.liveraven.net/cosmos-testnets/union/state-sync.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
