# System Detailed Logic

> **Introducing ADRO's three-step technological hierarchy designed to realize transparent rewards and immediate payments.**

ADRO PROTOCOL was designed to combine the reliability of blockchain with the practicality of payment networks. We build a scalable reward payment infrastructure by dividing the entire ecosystem into three core layers. In particular, we maximize data reliability by integrating IoT sensor data and AR interactions throughout the technological layers.

#### 🏗️ Architecture Overview

ADRO's architecture technically optimizes the flow from data generation to value conversion and final consumption.

1. **Protocol Layer :** Record of reliable data and reward logic (Core)
2. **Service Layer :** Intermediary layer that converts rewards into actual payment methods (Bridge)
3. **Application Layer :** Practical service interface experienced by users and merchants (Interface)

#### 1️⃣ Protocol Layer (Reward & Trust Layer)

**"The Foundation Where Assetization of Data Begins"**

As the lowest layer, it manages the issuance of all ad participation data and rewards (Token/Point).

* **ADRO Ledger :** Records ad viewing logs and AR participation history collected through IoT sensors on an unalterable on-chain ledger.
* **Smart Reward Contract :** An automated contract engine that immediately distributes rewards to users according to pre-defined reward logic.
* **Verification Node :** A security node that cross-references AR spatial computing and location data to verify that the advertiser's budget is executed correctly without fraudulent clicks.

#### 2️⃣ Service Layer (Finance & Payment Layer)

**"The Core Engine That Converts Points into Purchasing Power"**

A payment infrastructure layer that connects rewards generated in the protocol so they can be used in the real economy.

* **Hybrid Payment Gateway :** A hybrid PG solution that simultaneously processes digital assets and fiat currency payments.
* **Merchant API :** Real-time linkage between global merchant POS systems and the ADRO ecosystem to support IoT-based payments.
* **Valuation Engine :** Immediately converts reward value into payment amounts according to real-time exchange rates and merchant policies.

#### 3️⃣ Application Layer (User Experience Layer)

**"The Touchpoint of Service That Meets Daily Life"**

Includes applications and tools that users and merchants actually encounter.

* **ADRO User App :** An integrated wallet app providing AR ad viewing, reward management, and online/offline payment functions.
* **Partner SDK :** Supports external app developers to easily embed ADRO's reward and payment functions into their own services.
* **Merchant Dashboard :** A tool for merchants to manage real-time sales status and IoT-based payment data.
