# Overview

VDEXCore is powered by [Virtual Rollups](/protocol/whitepaper/virtual-rollup.md). Virtual Rollups are peer-to-peer channels that allow users to self-lock funds on blockchains and receive an equivalent balance state on VDEXCore. Balance states can be used as margin or redeemed for the respective onchain tokens.

As the user's balance changes through trading, the corresponding balance state is continuously signed by the user and counterparties. At any time, the fresh balance state can be permissionlessly settled onchain for an equal amount of tokens.

## 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.vdex.trade/introduction/virtual-rollups/overview.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.
