QuantumAI License Management System

A blockchain-based licensing system for AI model access control and monetization.

Overview

The QuantumAI License Management System provides:

  • Time-based access control for AI models
  • Automated license validation and enforcement
  • Usage-based billing and royalty collection
  • Programmatic access revocation
  • Transparent transaction history

Technical Architecture

Smart Contract Components

  1. License Token (ERC-1155)

    • Represents active license ownership
    • Includes metadata about license terms
    • Non-transferable implementation

  2. Revenue Sharing (ERC-2981)

    • Automated royalty distribution
    • Configurable revenue split
    • Per-transaction enforcement

  3. Access Control

    • Time-based validation
    • Grace period handling
    • Blacklist functionality

Implementation Guide

Contract Deployment

const contract = await QuantumAILicense.deploy(
  licenseFee,    // Base fee in wei
  royaltyRate    // Percentage (1-100)
);

License Management

// Purchase license
await contract.purchaseLicense(duration, { value: fee });

// Validate license
const isValid = await contract.hasValidLicense(address);

// Revoke access
await contract.revokeLicense(address);

API Integration

from web3 import Web3
from quantum_ai.licensing import LicenseValidator

def verify_access(user_address: str) -> bool:
    return await LicenseValidator.check_license(user_address)

Security Considerations

  • Immutable license records
  • Cryptographic access verification
  • Automated compliance enforcement
  • Transparent audit trail
