# Overview

## Introduction U2U Network

**U2U Network** is a **Layer 1** chain with superior **DAG** technology and **EVM** compatibility. With its high scalability and security, **U2U Network** is the most advanced platform for applications related to **AI**, **DePIN** (Decentralized Physical Infrastructure Network), **IoT** applications, and transportation. 

U2U develops a network scaling solution using **Subnet** **technology** - which helps increase performance and security for the entire system. Subnet allows the system to divide networks into smaller ones, enabling them to operate independently while ensuring smooth interaction with each other. This enables U2U Network to process data quickly without compromising security.

**Transaction completion time: 650ms**

**TPS up to 17K per shading**

## U2U Subnets

**U2U Subnet** is a set of peer-to-peer cryptography computers. It inherits the consensus and security layers of [**U2U Network**](<Https://u2u.xyz >) . 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.

U2U Network's Subnet technology helps optimize infrastructure, enhance performance, and security for the entire system. Thanks to this, decentralized projects can easily develop on this platform without facing barriers in terms of speed or technological complexity. The technological advantages and long-term vision of U2U Network have received investment and support from many VCs, Backers, aiming to become a leading decentralized infrastructure platform.

# Subnet Node Type


# Master Node

Master Nodes are integral components of the Subnet infrastructure, performing several critical functions:

**Transaction Management:**

* Store all Subnet transactions
* Validate all Subnet transactions

**Data Availability Layer (DAL):**

* Serve as the DAL for all Subnet Decentralized Applications
* Ensure data accessibility and integrity for the Subnet Ecosystem

**Cross-Network Operations:**

* Submit and Verify proofs between the Subnet and Mainnet
* Data Transmission between Subnet Protocols

**Reward Structure: Master Nodes receive compensation for their services through:**

* A portion of Subnet transaction fees
* Rewards for proof submission and verification between Subnet and Mainnet

*By fulfilling these roles, Master Nodes contribute to the security, reliability, and interoperability of the Subnet network, while also maintaining a connection with the main blockchain.*


# Verifier Node

Verifier Nodes leverage the **TEE** (Trusted Execution Environment) and **FHE** (Fully Homomorphic Encryption) technologies, it plays a crucial role for checking quality of service foreach Subnet Protocol, validate data integrity and maintaining the privacy of user's data.

* Data Versioning: Track changes in data and version control.
* Cyclic Redundancy Check (CRC): Detect errors in data transmission.
* Digital signatures: Use public key encryption to verify the origin and integrity of the data.
* Hash functions: Use algorithms such as MD5, SHA-256 to create a unique fingerprint for the data.


# Edge Node (or Contributor Node)

Edge Nodes are specialized components within the Subnet Ecosystem:

**Roles**: A node bound to specific protocols built on the Subnet Infrastructure

**Resource Contribution:** Edge Nodes can provide various computational resources to the Subnet, enhance the overall capacity and performance of the Subnet

* RAM (Memory)
* CPU (Processing power)
* GPU (Graphics processing capabilities)
* Storage (Data retention capacity)
* Internet bandwidth

**Reward Structure:**

Edge Nodes earn reward based on their contributed **DCU** (Distributed Computational Units) both from Network layer and Protocol layer (dual tokens mining)

**Protocol Specificity:** Each Edge Node is associated with a particular protocol, allowing for specialized functions within the Subnet Ecosystem

By leveraging these Edge Nodes, the Subnet can distribute computational tasks and storage requirements across a network of contributors, potentially improving scalability, resilience, and performance of the overall system.

# Benefit of purchasing DePIN Subnet Nodes

FOR EARLY ADOPTERS WHO HELP BOOTSTRAP THE DEPIN SUBNET

## 1B U2U - NODE REWARD POOL&#x20;

A reward pool containing 1 billion U2U tokens has been set aside exclusively for incentivizing DePIN Subnet node operators. This substantial pool will be disbursed gradually over a multi-year period, with the amount of rewards decreasing each year to ensure long-term sustainability and encourage early participation.

## Additional incentives (token) from other projects built on DePIN Subnet

In addition to rewards from the U2U token pool, other projects built on the DePIN Subnet can also offer additional incentives using their own tokens to attract users and encourage application usage. This will create a vibrant and diverse ecosystem, benefiting both users and developers.
