# Modules The core of GRID is the gateway daemon running on each provider and the platform server offering many APIs for user and provider to interact with the smart contracts on chain. Kubernetes and nodes must be deployed on each provider to make computing power available before they can provide service to users and gain profit. The smart contracts on chain are used for provider info management and settlement funcionality. --- # 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.
