# Architecture

This section provides a high-level overview of the architecture of Glow and the key smart contracts that constitute the Glow Ecosystem.

Glow smart contracts are categorized into two groups:

* **Core.** Set of smart contracts that constitute the backbone of the Glow ecosystem and are used by Glow apps.
* **Apps.** Product-specific contracts or a set of contracts that manage the business logic of a specific app. The **Glow** **Lotto smart contract** is an example of this.
