# Overview

## Introduction

**U2U Subnet** is a set of peer-to-peer cryptography computers. It inherits the consensus and security layers of **U2U Network** . Subnet utilizes the **OVM** (Ostracism Virtual Machine), which is a high-speed graph reduction virtual machine designed to perform **Subnet DApps** (Subnet Decentralized Applications). The **OVM** compiles code written in various languages such as Python, Go, Rust, and TypeScript into a **Runtime**. This Runtime allows formally verified applications to run natively on the network, ensuring maximum mathematical security.

**Subnet** allows node operators contribute their computing resources to the network (eg CPU, RAM, GPU, Storage, Internet...), from mobile phone to super computer, forming a Decentralized Physical Infrastructure Network (**DePIN**) capable of hosting applications that stay up forever.
