OGPU Smart Contracts

🛠 Smart Contract Infrastructure for OpGPU

To deliver a decentralized GPU rental marketplace, OpGPU leverages a suite of modular smart contracts deployed on a high-performance EVM-compatible blockchain (e.g., Ethereum L2 or sidechain). These contracts automate the coordination, validation, and incentivization of interactions between GPU Providers, Clients, and the OpGPU Network.

📜 Key Smart Contracts and Their Roles


1. TaskManager.sol

  • Purpose: Orchestrates the creation, bidding, assignment, and completion of GPU tasks.

  • Key Functions:

    • submitTask(taskMetadata, budget, duration): Client submits a job request.

    • placeBid(taskId, providerId, price): Providers offer computational services.

    • assignProvider(taskId, providerId): Assigns the best-fit provider based on trust score and pricing.

    • verifyCompletion(taskId, resultHash): Called by oracles or verification nodes to validate task output.

    • finalizePayment(taskId): Triggers payment from escrow to provider upon task approval.


2. StakingVault.sol

  • Purpose: Handles staking of oGPU tokens by both providers and clients to enforce commitment and reduce spam.

  • Key Features:

    • Providers stake to increase visibility and reputation.

    • Clients stake to commit to task budget.

    • Slashing mechanism for malicious or failed behavior.


3. PaymentEscrow.sol

  • Purpose: Manages secure, time-locked, and conditional payment flows.

  • Workflow:

    • oGPU tokens are locked when a task is created.

    • Released only when verified as successfully completed.

    • If a dispute arises, funds are held until DAO arbitration.


4. ReputationRegistry.sol

  • Purpose: Tracks and maintains scores for all participants based on past performance, completion rate, and user feedback.

  • Mechanics:

    • Points added for timely, high-quality task delivery.

    • Penalized for incomplete or incorrect outputs.

    • DAO can review disputed scores for transparency.


5. GovernanceDAO.sol

  • Purpose: Allows token holders to vote on protocol-level decisions (e.g., fee structure, contract upgrades, slashing conditions).

  • Integrates With: Snapshot or Tally for off-chain voting, plus on-chain execution logic.


🔐 Security and Design Considerations

  • Modular Contracts: Each component is upgradeable via proxy patterns (e.g., OpenZeppelin’s UUPS).

  • Oracle Integration: For external verification (e.g., hash comparison, latency checks).

  • ZKP or MPC Layer (Future): For privacy-preserving computation verification (especially for AI models and sensitive data).

  • Failsafes: Watchdog contracts + emergency circuit breakers for high-value tasks.


🚀 Outcome: Fully Trustless Compute Market

With this smart contract infrastructure, OpGPU enables a self-sustaining, censorship-resistant, and fair marketplace for decentralized computing — where:

  • Anyone can contribute idle GPU power.

  • Workflows are automated without intermediaries.

  • Payments and penalties are enforced transparently.
