Distributed AI Network

Distributed AI Network

Hyra Network implements a fully decentralized AI architecture where all task distribution, reward management, and data handling are managed by smart contracts on the blockchain, eliminating the need for centralized backend systems.

Evolution from Backend to On-Chain

Before: Centralized Backend System

└─────────────────────────────────────────────────────────────┘

Problems with Backend Approach:

• Single Point of Failure: Server downtime affects entire network
• Centralized Control: Backend operator controls all data and rewards
• Privacy Concerns: All data stored on centralized servers
• Scalability Issues: Limited by server capacity
• Trust Requirements: Users must trust the backend operator

Now: Fully On-Chain Smart Contract System

Benefits of On-Chain Approach:

• Decentralized: No single point of failure
• Transparent: All operations are public and verifiable
• Trustless: No need to trust a central authority
• Immutable: Smart contract logic cannot be changed arbitrarily
• Global: Accessible from anywhere in the world

Smart Contract Architecture

Core Smart Contracts

1. ModelRegistry Contract

contract ModelRegistry {
    struct Model {
        string modelName;
        string modelDescription;
        uint256 modelTokenPrice;
        bool modelIsActive;
        address modelOwner;
    }

    // Register new AI models
    function registerModel(string memory name, string memory description, uint256 price) external;

    // Get model information
    function getModel(uint256 modelId) external view returns (Model memory);

    // Update model pricing
    function updateModelPrice(uint256 modelId, uint256 newPrice) external;
}

Responsibilities:

• Model Management: Register and manage AI models
• Pricing: Set and update model pricing in HYRA tokens
• Versioning: Track model versions and updates
• Access Control: Manage model ownership and permissions

2. TaskPoolFactory Contract

contract TaskPoolFactory {
    // Create new task pools
    function createTaskPool(string memory name, address modelAddress) external returns (address);

    // Get all task pools
    function getAllTaskPools() external view returns (address[] memory);

    // Get task pool by ID
    function getTaskPool(uint256 poolId) external view returns (address);
}

Responsibilities:

• Pool Creation: Create new task pools for different AI models
• Pool Management: Track and manage all task pools
• Pool Discovery: Allow workers to find available pools

3. TaskPoolImplementation Contract

contract TaskPoolImplementation {
    struct Task {
        uint256 taskId;
        string inputData;
        string expectedOutput;
        uint256 reward;
        uint256 deadline;
        address assignedWorker;
        bool isCompleted;
    }

    // Submit new tasks
    function submitTask(string memory inputData, uint256 reward) external payable;

    // Claim tasks
    function claimTask() external returns (Task memory);

    // Submit results
    function submitResult(uint256 taskId, string memory result, bytes memory zkpProof) external;
}

Responsibilities:

• Task Management: Create, assign, and track tasks
• Worker Assignment: Assign tasks to available workers
• Result Submission: Handle task result submissions
• Reward Distribution: Distribute HYRA tokens to workers

4. TaskRouter Contract

contract TaskRouter {
    // Route tasks to appropriate pools
    function routeTask(uint256 modelId, string memory inputData) external payable;

    // Get available tasks
    function getAvailableTasks() external view returns (Task[] memory);

    // Worker task management
    function claimTaskFromPool(address poolAddress) external returns (Task memory);
}

Responsibilities:

• Task Routing: Route tasks to appropriate pools
• Load Balancing: Distribute tasks across multiple pools
• Worker Discovery: Help workers find available tasks
• Pool Coordination: Coordinate between different task pools

On-Chain Data Structure

Public Data Storage

All data is stored on-chain and is publicly accessible:

// Task data structure
struct Task {
    uint256 taskId;           // Unique task identifier
    string inputData;         // Encrypted input data
    string expectedOutput;     // Expected output format
    uint256 reward;           // HYRA token reward
    uint256 deadline;         // Task deadline
    address assignedWorker;    // Worker address
    bool isCompleted;         // Completion status
    bytes zkpProof;           // Zero-knowledge proof
}

// Worker data structure
struct Worker {
    address workerAddress;    // Worker wallet address
    uint256 totalTasks;       // Total tasks completed
    uint256 totalRewards;     // Total HYRA earned
    uint256 reputation;       // Worker reputation score
    bool isActive;            // Active status
}

Data Transparency

• Task History: All tasks are publicly visible
• Worker Performance: Worker statistics are public
• Reward Distribution: All payments are transparent
• Model Performance: AI model statistics are public

Network Roles in On-Chain System

1. AI End Users

• Submit Tasks: Pay HYRA tokens and submit AI inference requests
• Access Results: Retrieve completed AI results
• Model Selection: Choose from available AI models
• Payment: Pay for services using HYRA tokens

2. AI Workers

• Claim Tasks: Get tasks from smart contracts
• Process Tasks: Run AI models and generate results
• Submit Results: Submit results with ZKP proofs
• Earn Rewards: Receive HYRA tokens for completed tasks

3. Verifiers

• Verify Proofs: Validate ZKP proofs submitted by workers
• Distribute Rewards: Trigger reward distribution to workers
• Maintain Quality: Ensure network quality and prevent cheating
• Governance: Participate in network governance

Benefits of On-Chain Architecture

1. Decentralization

• No Single Point of Failure: Network continues even if some nodes fail
• No Central Authority: No single entity controls the network
• Global Access: Anyone can participate from anywhere
• Censorship Resistant: Cannot be shut down by authorities

2. Transparency

• Public Data: All operations are visible on blockchain
• Verifiable: Anyone can verify network operations
• Auditable: Complete audit trail of all activities
• Trustless: No need to trust central authorities

3. Security

• Cryptographic Guarantees: Smart contracts provide security guarantees
• Immutable Logic: Contract logic cannot be changed arbitrarily
• ZKP Verification: Zero-knowledge proofs ensure computation integrity
• Encrypted Data: All sensitive data is encrypted

4. Efficiency

• Automated Operations: Smart contracts handle all operations automatically
• Reduced Costs: No need for centralized infrastructure
• Global Scale: Handle operations at global scale
• 24/7 Availability: Network operates continuously

Smart Contract Workflow

1. Task Submission

// User submits task to ModelRegistry
function submitInferenceRequest(uint256 modelId, string memory inputData) external payable {
    // Validate payment
    require(msg.value >= modelPrice, "Insufficient payment");

    // Create task in appropriate pool
    address poolAddress = getTaskPoolForModel(modelId);
    TaskPoolImplementation pool = TaskPoolImplementation(poolAddress);
    pool.submitTask(inputData, msg.value);
}

2. Task Assignment

// Worker claims task from pool
function claimTask() external returns (Task memory) {
    // Check if worker has active task
    require(activeTasks[msg.sender] == 0, "Worker has active task");

    // Assign task to worker
    Task memory task = getNextAvailableTask();
    activeTasks[msg.sender] = task.taskId;

    return task;
}

3. Result Submission

// Worker submits result with ZKP proof
function submitResult(uint256 taskId, string memory result, bytes memory zkpProof) external {
    // Verify ZKP proof
    require(verifyZKPProof(taskId, result, zkpProof), "Invalid ZKP proof");

    // Update task status
    tasks[taskId].isCompleted = true;
    tasks[taskId].result = result;

    // Distribute reward
    uint256 reward = tasks[taskId].reward;
    payable(msg.sender).transfer(reward);
}

Getting Started with On-Chain System

1. Connect to Hyra Network

// Connect to Hyra Network
const provider = new ethers.providers.JsonRpcProvider(
  "https://rpc.hyra.network"
);
const wallet = new ethers.Wallet(PRIVATE_KEY, provider);

2. Interact with Smart Contracts

// Get task from smart contract
const taskPool = new ethers.Contract(TASK_POOL_ADDRESS, TASK_POOL_ABI, wallet);
const task = await taskPool.claimTask();

// Submit result
await taskPool.submitResult(task.taskId, result, zkpProof);

3. Monitor Network Activity

// Listen to smart contract events
taskPool.on("TaskCompleted", (taskId, worker, reward) => {
  console.log(`Task ${taskId} completed by ${worker} for ${reward} HYRA`);
});
