NZIDIA – The ZPU Network

The Decentralized Compute Layer for Private AI

---

🧠 Introduction

NZIDIA is building the ZPU (Zero-Knowledge Processing Unit) — a decentralized, privacy-first compute network that redefines how AI and high-performance computation are executed on-chain.

While GPUs powered the centralized AI revolution, ZPUs are the cryptographically verifiable evolution — decentralized compute units that enable private, permissionless, and verifiable computation using zero-knowledge proofs (zkSNARKs).

ZPU = GPU × ZK × Web3
Compute without exposure. Verify without trust.

⚙️ Architecture Overview

ZPU Network Layers

The NZIDIA network is composed of four primary layers:

1. Client Layer – The interface for developers and agents to submit compute requests using the NZIDIA SDK or REST API.
2. ZPU Node Layer – A network of decentralized compute providers that execute workloads securely within zero-knowledge environments.
3. Proof Layer (zkSNARK Engine) – Validates computations cryptographically without revealing inputs, intermediate states, or model parameters.
4. Consensus & Settlement Layer – Anchored on ZCash-based zero-knowledge ledgers, ensuring integrity, staking, and rewards.

🧩 ZPU Node Design

Each ZPU Node acts as a micro datacenter, executing encrypted compute workloads and producing zk-proofs of correctness. Nodes can be GPU-backed, CPU-backed, or hybrid configurations optimized for zkVM workloads.

Node Components

• Executor: Runs the compute task inside a ZK-sandboxed container.
• Prover: Generates zkSNARKs attesting to correctness of execution.
• Verifier: Submits proof to on-chain verifier contracts.
• Staker: Locks $NZIDIA tokens to ensure honesty and anti-Sybil guarantees.

Proof Workflow

1. User submits a task to the ZPU Network.
2. Task is encrypted and dispatched to an available node.
3. Node executes computation and generates zkSNARK proof.
4. Proof is verified by the on-chain Verifier module.
5. Node receives $NZIDIA rewards after successful verification.

🔬 zkCompute Pipeline

The ZPU framework uses a deterministic zkVM to ensure reproducibility across all compute nodes.

💡 Developer SDK

Node Setup

git clone https://github.com/nzidia/zpu-node
cd zpu-node
cargo build --release
./target/release/zpu-node --register-node --stake 1000NZIDIA

Client SDK

import { ZPUClient } from "@nzidia/sdk";

const client = new ZPUClient("https://api.nzidia.com");

const result = await client.submitJob({
  model: "private-llm-v1",
  input: { prompt: "Generate zk-secure summary" },
  maxBudget: 2500,
});

console.log("Job ID:", result.jobId);
console.log("Proof URL:", result.proofUrl);

🔒 Security & Privacy Model

Core Guarantees

• Zero Data Leakage: All job inputs, weights, and outputs are encrypted end-to-end.
• Verifiable Execution: zkProofs guarantee deterministic computation.
• Censorship Resistance: Decentralized node orchestration via libp2p.
• Economic Security: Nodes stake $NZIDIA; slashed upon invalid proofs or downtime.
