# Overview

RealiOS is composed of three core layers that work together seamlessly:

| Layer                  | Role                                                                    | Core Components                                   |
| ---------------------- | ----------------------------------------------------------------------- | ------------------------------------------------- |
| **Data Layer**         | Handles real-world data collection from users’ devices and sensors.     | Mobile SDK, Sensor Modules, Encryption Engine     |
| **Verification Layer** | Validates, timestamps, and verifies the authenticity of submitted data. | Smart Contracts, Oracle Bridge, Geo-Verifier      |
| **Incentive Layer**    | Distributes rewards, manages missions, and handles contributor payouts. | Reward Contracts, Treasury Pool, Mission Registry |

Each layer interacts through a combination of **encrypted peer-to-peer communication** and **on-chain event logs**, ensuring transparency, security, and decentralization.

#### Key Principles

* **User Ownership:** All data originates from user-owned devices; no third party can claim ownership or modify submissions.
* **Privacy Preservation:** Each packet is anonymized and encrypted before leaving the device.
* **Verifiability:** Every piece of data can be independently verified by the blockchain.
* **Fair Incentives:** Rewards are calculated automatically based on verified participation and mission weighting.

RealiOS bridges physical reality and digital infrastructure  creating a unified, permissionless network for real-world data.
