# Node Types & Responsibilities

#### **Compute Node**

**Purpose:**\
Performs private computation, zk proof generation, and AI inference tasks for zkShine’s network.

**Responsibilities:**

* Generate zk-SNARK/zk-STARK proofs for user computations
* Validate proofs submitted from other nodes
* Maintain proof integrity and task history

**Reward Source:**\
Compute verification fees + network rewards.

#### **Relayer Node**

**Purpose:**\
Ensures **transaction anonymity** by rebroadcasting Solana transactions through encrypted relay paths.

**Responsibilities:**

* Receive transactions from zkGateway
* Strip metadata and rebroadcast to Solana validators
* Maintain randomized routing for unlinkability

**Reward Source:**\
Relay fees proportional to traffic volume and uptime.

#### **VPN Node**

**Purpose:**\
Provides **decentralized RPC routing** and privacy tunnels for dApps and wallets.

**Responsibilities:**

* Route encrypted RPC traffic
* Rotate session identifiers
* Ensure no logs or IP traces are kept

**Reward Source:**\
Bandwidth fees + zkVPN usage payments.

#### **Vault Node**

**Purpose:**\
Handles zkVault encrypted storage and zk access control proofs.

**Responsibilities:**

* Store encrypted user data in decentralized shards
* Respond to zk-proof-based access requests
* Maintain 99.9% data availability

**Reward Source:**\
Storage allocation + proof validation rewards.
