Smart Contract Architecture

DTA implements a sophisticated multi-layer architecture designed for the Digital Twin & AI ecosystem:

contract DTA is ERC20, ERC20Pausable, ERC20Burnable, Ownable, ReentrancyGuard {
    // Digital Twin Integration Layer
    mapping(address => uint256) public contributionRewards;
    mapping(address => bool) public blacklisted;
    
    // AI & Data Economy Layer
    struct StakeInfo {
        uint256 amount;          // Staked amount for computing power
        uint256 startTime;       // Stake timestamp
        uint256 lockPeriod;      // Lock period in days
        bool isActive;           // Active status
    }
    
    // DAO Governance Layer
    struct Proposal {
        uint256 id;              // Proposal ID
        address proposer;        // Proposal creator
        string title;            // Proposal title
        string description;      // Detailed description
        uint256 votingStart;     // Voting start time
        uint256 votingEnd;       // Voting end time
        // ... governance mechanics
    }
}
