# Arbitrum Nitro on 0G DA

> Run an Arbitrum Nitro rollup with 0G DA for cost-effective data availability. Includes DA provider integration and setup prerequisites.


Arbitrum Nitro is a high-performance Ethereum rollup that uses a new consensus mechanism called "Nitro" to achieve scalability and efficiency. 0G DA is a high-performance data availability layer that can be used for Arbitrum Nitro to provide a cost-effective and secure solution for storing transaction data.

## Overview

### DA Provider Implementation

The Arbitrum Nitro code includes a `DataAvailabilityProvider` interface, which is utilized throughout the codebase for storing and retrieving data from various providers, including EIP-4844 blobs, Anytrust, and now 0G.

This integration adds an implementation of the `DataAvailabilityProvider` interface specifically for 0G. The main functionality for posting and retrieving data is found in the `das/zerogravity.go` file, where the data is stored on 0G.
