# Three-Layer Architecture

FMIP operates on a modular architecture composed of three interconnected layers, each fulfilling a distinct role within the protocol’s ecosystem.

### Mining Layer — Passive Connectivity Rewards

The Mining Layer transforms network participation into measurable, protocol-native value.

Users activate virtual Miners within the Depinsim App, which verify uptime, stability, and traffic integrity through blockchain-based metrics.\
Each verified contribution generates **Mined Data**, the protocol’s native yield derived from **Proof-of-Connection (PoC²)** validation.

* **Proof-of-Connection (PoC²)** ensures that every online device contributes real bandwidth and verifiable network activity
* **Mined Data** represents transferable proof of productive connectivity
* Rewards scale based on network activity, coverage duration, and participation consistency

Through this mechanism, Depinsim introduces a sustainable earning model — where **connection itself produces continuous passive value**.

### Network Layer — Borderless Global Connectivity

The Network Layer integrates multi-carrier eSIM technology with blockchain validation to form a unified, borderless connectivity network.

Each Depinsim eSIM functions as a decentralized access credential, enabling global connectivity without SIM swaps, carrier contracts, or regional restrictions.

Key features include:

* **Seamless Network Management** — automatic switching between networks across countries and regions with zero downtime
* **Decentralized Access Control** — identity and authentication handled cryptographically rather than by centralized telecom providers
* **Continuous Connectivity** — persistent global access maintained through verifiable network nodes

Whether traveling across continents or operating distributed businesses, users experience uninterrupted global roaming — coordinated by the protocol, not by carriers.

### Value Layer — Data-to-Value Conversion

The Value Layer bridges protocol-level participation with real-world utility.

**Mined Data** earned through network contribution can be utilized in two primary ways:

#### Convert to $ESIM Tokens

Mined Data can be converted into **$ESIM tokens**, the native utility token of the Depinsim ecosystem, representing the on-chain value of verified connectivity contribution.

#### Redeem for eSIM Data Services

Mined Data can also be redeemed directly for global eSIM data packages, enabling users to access mobile connectivity without additional payment.

Together, these mechanisms form a closed-loop incentive cycle:

> **Connect → Mine → Convert → Use → Connect Again**

As participation increases, network coverage expands, utility grows, and value circulation strengthens — resulting in a self-reinforcing mobile data economy driven entirely by user activity.
