Advanced Example: AI Marketplace

The AI Marketplace example demonstrates a comprehensive platform where various AI components can be registered, priced, executed, and rated. This platform uses the native $BASED token for transactional activities and incorporates a reputation system for quality assurance. It showcases the potential of tokenizing AI components and incentivizing their development and usage within a decentralized ecosystem.

Concept

• AI Component Registration: Allows AI developers to register their AI components on the marketplace, setting a price for each execution.

• Reputation System: Each AI component has a reputation score which influences its perceived quality and reliability.

• Usage Tracking: Tracks the number of times each AI component is executed.

• Payment Handling: Ensures proper compensation for AI component execution using $BASED.

• Dynamic Pricing: Adjusts the price of execution based on usage and reputation.

• Reputation Adjustment: Enables users to adjust the reputation score by sending $BASED tokens, ensuring a community-driven quality control mechanism.

Steps to Implement the AI Marketplace

1. Create and Deploy the AI Component Interface (IAIComponent)

This interface defines the standard functions that each AI component contract must implement.

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

interface IAIComponent {
    // Returns description and owner information about the component
    function getInfo() external view returns (string memory description, address owner);

    // Executes the component with given input data, returns the output data
    function execute(bytes memory inputData) external returns (bytes memory outputData);

    // Used to retrieve the current price per execution of the component
    function getPrice() external view returns (uint256 pricePerExecution);

    // Used to retrieve the current reputation score of the component
    function getReputation() external view returns (uint256 reputationScore);
}

2. Create and Deploy the AI Marketplace Contract (BasedAIMarketplace)

This smart contract manages the registration, execution, pricing, and reputation of AI components.

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "./IAIComponent.sol";

// AI Marketplace Contract
contract BasedAIMarketplace {
    struct AIComponent {
        address componentAddress;

        address owner;
        uint256 pricePerExecution;
        uint256 reputationScore;
    }

    AIComponent[] public aiComponents;
    mapping(address => bool) public isComponentRegistered;

    event ReputationUpdated(address indexed componentAddress, uint256 newReputationScore);
    event ReputationAdjusted(address indexed componentAddress, uint256 amount, bool increased);
    event DynamicPriceUpdated(address indexed componentAddress, uint256 newPrice);

    modifier onlyComponentOwner(address componentAddress) {
        (, address owner) = IAIComponent(componentAddress).getInfo();
        require(msg.sender == owner, "Caller is not the component owner.");
        _;
    }

    function registerComponent(address componentAddress, uint256 pricePerExecution) external {
        require(!isComponentRegistered[componentAddress], "Component already registered.");
        (string memory description, address owner) = IAIComponent(componentAddress).getInfo();
        aiComponents.push(AIComponent(componentAddress, description, owner, pricePerExecution, 0));
        isComponentRegistered[componentAddress] = true;
        emit ComponentRegistered(componentAddress, description);
    }

    function unregisterComponent(address componentAddress) external onlyComponentOwner(componentAddress) {

        for (uint256 i = 0; i < aiComponents.length; i++) {
            if (aiComponents[i].componentAddress == componentAddress) {
                aiComponents[i] = aiComponents[aiComponents.length - 1];
                aiComponents.pop();
                break;
            }
        }
        emit ComponentUnregistered(componentAddress);
    }

    function executeComponent(uint256 componentIndex, bytes memory inputData) external payable returns (bytes memory outputData) {
        require(componentIndex < aiComponents.length, "Invalid component index.");
        AIComponent memory aiComponent = aiComponents[componentIndex];
        require(msg.value >= aiComponent.pricePerExecution, "Insufficient payment for execution.");

        outputData = IAIComponent(aiComponent.componentAddress).execute(inputData);
        payable(aiComponent.owner).transfer(aiComponent.pricePerExecution);
        componentUsageCount[aiComponent.componentAddress]++;
        emit ExecutionCompleted(aiComponent.componentAddress, outputData);
        emit PaymentTransferred(aiComponent.componentAddress, msg.sender, aiComponent.pricePerExecution);

    function updateReputation(address componentAddress, uint256 newReputationScore) external onlyComponentOwner(componentAddress) {

        }

        // Burn the $BASED sent for reputation adjustment (sent to address(0))
        payable(address(0)).transfer(msg.value);

        emit ReputationAdjusted(componentAddress, adjustment, increase);
        emit ReputationUpdated(componentAddress, aiComponent.reputationScore);
    }

    function rateComponent(address componentAddress, uint256 rating) external {
        require(isComponentRegistered[componentAddress], "Component not registered.");
        require(rating > 0 && rating <= 5, "Rating must be between 1 and 5.");

        uint256 currentReputation = aiComponent.reputationScore;
        uint256 currentUsageCount = componentUsageCount[componentAddress];

        // Simple weighted average calculation for reputation score update
        aiComponent.reputationScore = (currentReputation * currentUsageCount + rating) / (currentUsageCount + 1);
        componentUsageCount[componentAddress]++;

        emit ReputationUpdated(componentAddress, aiComponent.reputationScore);
    }

    function _findComponentIndex(address componentAddress) internal view returns (uint256) {

                return i;
            }
        }
        revert("Component not found.");
    }

    // Function to implement dynamic pricing based on various factors
    function updateDynamicPricing(address componentAddress, uint256 basePrice, uint256 demandFactor, uint256 reputationFactor) external onlyComponentOwner(componentAddress) {
        require(isComponentRegistered[componentAddress], "Component not registered.");
        AIComponent storage aiComponent = aiComponents[_findComponentIndex(componentAddress)];

        // Calculate the new price based on demand and reputation
        uint256 demandPrice = basePrice + (componentUsageCount[componentAddress] * demandFactor);

  • Can register AI components and specify the price per execution.

  • Execute AI components by paying with $BASED and receive results.

  • Adjust the reputation of AI components by burning $BASED tokens.

  • Rate AI components based on performance.

• Component Owners:

  • Register and unregister their AI components.

  • Update reputation scores and manage component details.

  • Receive payments in $BASED for AI component usage.

  • Implement dynamic pricing based on usage and reputation.

  • Tracks usage and handles payments and refunds.

  • Facilitates reputation adjustments and dynamic pricing.

Future Enhancements with AI Integration:

• AI-Driven Component Discovery:

  • Initial State: Users manually browse and search for AI components to execute.

  • Future State: AI algorithms recommend AI components to users based on their needs, preferences, and historical usage patterns.

• Dynamic Resource Allocation:

  • Initial State: Static pricing and fixed resource allocation.

  • Future State: AI-driven resource management dynamically adjusts prices, allocates resources based on demand, and optimizes the utilization of AI components.

By integrating these AI-driven enhancements, the AI Marketplace can evolve to become more intelligent, efficient, and adaptive, fostering innovation and effective utilization of AI resources.
