# Run a chain via snapshot

## Workflow of running a chain node 

* Download snapshot

Method 1:

```
wget https://chain-snapshot-data.bool.network/beta-testnet-node-snapshot-latest.zip
```

* Replace data

beta-testnet-node-snapshot-latest.zip  has been downloaded. Unzip the beta-testnet-node-snapshot-latest.zip  to the specified chain node data directory, replace the original data directory node-data, and then restart the chain service node. Assume that your link node data directory is `~/bool-beta-testnode`

```
mv ~/bool-beta-testnode/node-data ~/bool-beta-testnode/node-data_old
unzip beta-testnet-node-snapshot-latest.zip -d ~/bool-beta-testnode/
```

* (Optional) Modify docker-compose.yaml

Modify the node's docker-compose.yaml configuration to remove `--state-pruning archive` and `--block-pruning archive`

```
sed -i '/--state-pruning archive/d;/--blocks-pruning archive/d' docker-compose.yaml
```

* Start the chain service node

```
docker-compose up -d
```

## 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, and the optional `goal` query parameter:

```
GET https://docs.deepsafe.network/user-guide/crva-maintaining/run-a-chain-via-snapshot.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
