# DIA Stack Overview

> DIA is a fully on-chain, trustless oracle architecture featuring permissionless access and modular design, powered by an Ethereum Layer-2 core. Developed by DIA, open for all.

## Introduction to DIA

DIA's architecture focuses on maximizing decentralization and trustless execution. It is composed of state-of-the-art modular components that use Lasernet, DIA’s native Ethereum layer-2 rollup, as its core settlement layer for critical data operations such as computation and verification.

DIA tackles traditional blockchain oracles' issues through its rollup-powered architecture:

* Independent nodes fetch data directly from sources (CEXs, DEXs, more)
* Data is submitted on-chain to DIA Lasernet – DIA's ETH L2 rollup
* Processing and aggregation of data happen on-chain
* Transactions are settled on-chain transparently

## Data Flow: From Source to Feed

DIA is composed of three main stages, each critical to ensuring the accuracy, reliability, and accessibility of your data.
