Nexus Network Whitepaper

Decentralized compute marketplace for Ghost Neural Network. Lend GPU power to earn GNN tokens, access TOMO's AI trading intelligence remotely, with secure trade intent signing.

Last updated: January 15, 2026

“Lend your GPU. Earn GNN. Power the collective intelligence.”

What is Nexus?

Nexus is a decentralized compute marketplace that enables:

1. Node Providers — Users with WebLLM-capable machines to lend their compute power and earn GNN tokens
2. Consumers — Users without capable hardware to access TOMO’s AI trading intelligence remotely
3. Secure Delegation — Cryptographically verified trade execution using the consumer’s own wallet

Why Build This?

TOMO requires substantial compute (7B+ parameter models) that many devices cannot provide locally. Rather than centralizing this on expensive cloud infrastructure, Nexus creates a peer-to-peer compute economy where:

• Idle GPU cycles become productive assets
• GNN token holders benefit from network participation
• The network becomes more resilient and distributed over time
• Users retain custody of their funds while delegating compute

The Problem

The Hardware Divide

~70% of potential users cannot run TOMO locally.

Current Solutions & Limitations

The Three Actors

Consumer

• User who needs TOMO but lacks capable hardware
• Holds a wallet with funds to trade AND GNN to pay for compute
• Delegates AI inference, never delegates wallet keys

Provider (Node Operator)

• User with WebLLM-capable hardware willing to share compute
• Runs the Nexus Node Agent (containerized TOMO engine)
• Earns GNN tokens for completed work units

Coordinator

• The Nexus protocol layer (smart contracts + off-chain services)
• Handles discovery, matching, metering, payments, disputes
• Initially semi-centralized, progressively decentralizing

Key Innovation: Trade Intent Signing

The critical challenge: How can a remote node execute trades using the consumer’s wallet without having access to their private keys?

Solution: Signed Trade Intents

1. Consumer ──► Nexus Node: "Analyze BONK"

2. Nexus Node ──► Consumer: Trade Intent {
      action: "BUY",
      token: "BONK",
      amount: 0.5 SOL,
      maxSlippage: 1%,
      rationale: "Strong momentum...",
      confidence: 0.82,
      expires: 30 seconds
   }

3. Consumer reviews intent locally

4. Consumer ──► Wallet: Sign transaction for intent

5. Signed TX ──► Solana: Execute swap

6. Consumer ──► Nexus Node: "Trade executed, txid: xxx"

The node never sees or controls the private key. It proposes trades; the consumer signs them locally.

Provider Staking Tiers

Staking serves multiple purposes:

• Skin in the game for quality service
• Slashing collateral for misbehavior
• Governance weight for protocol decisions

Economic Model

Session-Based Pricing

Provider Earnings

Providers earn based on:

• Compute time provided (metered in inference tokens)
• Session completion rate
• Performance tier multiplier
• Reputation score bonus

Slashing Conditions

Goals & Metrics

Non-Goals (Out of Scope)

• General-purpose compute (not competing with Akash)
• Running arbitrary models (locked to TOMO-approved models)
• Custodial services (users always control their keys)
• Fully trustless operation (some trust assumptions required initially)

Inspiration

This system draws inspiration from:

• Nexus zkVM — Decentralized proving network for zero-knowledge computation
• Akash Network — Decentralized cloud compute marketplace
• Render Network — Distributed GPU rendering
• Bittensor — Decentralized machine learning network

Unlike general compute networks, Nexus is purpose-built for AI-powered trading, with specialized trust mechanisms for financial operations.
