# 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. --- # 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.
