# Rollback Blocks

This guide describes how to revert the Pharos node to a previous block height.

## Step 1: Stop the Node

**Docker:**

```bash
cd /data/$WORKSPACE
docker compose down
```

**Binary:**

```bash
cd /data/$WORKSPACE
./ops stop
```

## Step 2: Backup local\_storage

```bash
mv /data/$WORKSPACE/data/local_storage /data/$WORKSPACE/data/local_storage.bak
```

## Step 3: Revert Blocks

**Revert to latest stable block:**

```bash
cd /data/$WORKSPACE/bin
LD_PRELOAD=./libevmone.so ./pharos_cli revert -c ../pharos.conf -t stable
```

**Revert to a specific block number:**

```bash
cd /data/$WORKSPACE/bin
LD_PRELOAD=./libevmone.so ./pharos_cli revert -c ../pharos.conf -t stable -n 1234567
```

You will see an interactive confirmation prompt:

```
You are trying to revert stable block to 1234567, are you sure? [y/n]
```

Enter `y` to confirm.

## Step 4: Start the Node

**Docker:**

```bash
cd /data/$WORKSPACE
docker compose up -d
```

**Binary:**

```bash
./ops start --config ./pharos.conf
```

## 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.pharos.xyz/node-and-validator-guide/rollback-blocks.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.
