# Node Operator Network

### **Node Operator Network**

#### **Overview**

The **Node Operator Network** is the decentralized foundation that powers zkShine’s privacy ecosystem.\
Each node performs specialized roles from computing proofs to relaying transactions contributing directly to the network’s privacy, reliability, and scalability.

#### **Node Types**

| Node Type        | Function                                                  | Reward Source              |
| ---------------- | --------------------------------------------------------- | -------------------------- |
| **Compute Node** | Generates zk-SNARK/zk-STARK proofs for confidential tasks | Proof verification fees    |
| **Relayer Node** | Anonymizes and rebroadcasts Solana transactions           | Relay service fees         |
| **VPN Node**     | Provides encrypted network access for RPC users           | Bandwidth fees             |
| **Vault Node**   | Hosts encrypted zkVault data                              | Storage allocation rewards |

#### **Reward Mechanism**

* Nodes earn rewards based on **uptime, bandwidth, and task completion**.
* zkDAO tracks performance metrics using verifiable ZK attestations.
* Rewards are automatically distributed via smart contracts every epoch.

#### **Governance Integration**

All node operators are **automatically enrolled in zkDAO governance**, giving them voting rights and proposal privileges proportional to their node reputation and stake.

#### **Advantages**

* Fully decentralized and self-sustaining infrastructure
* Rewards aligned with network performance
* Transparent verification through ZK proofs
* No central authority or data exposure
