📜 Contract System Design

Core Contract Modules

// Main Contract Architecture
MythoriaCore.sol           // Core protocol contract
├── NodeManager.sol        // Node management contract
├── TokenManager.sol       // Token management contract

Detailed Smart Contract Specifications

1. MythoriaCore.sol - Core Protocol Contract

pragma solidity ^0.8.19;

contract MythoriaCore {
    // State variables
    mapping(address => UserProfile) public users;
    mapping(uint256 => NodeInfo) public nodes;
    
    // Core functions
    function initialize() external;
    function upgradeProtocol(bytes calldata data) external;
    function emergencyPause() external;
    function setOracleAddress(address oracle) external;
    
    // Event definitions
    event UserRegistered(address indexed user, uint256 timestamp);
    event ProtocolUpgraded(uint256 version, bytes32 hash);
    event EmergencyActivated(address indexed admin, string reason);
}

2. NFTHeroSystem.sol - NFT Hero System

contract NFTHeroSystem is ERC721, AccessControl {
    struct Hero {
        uint256 tokenId;
        uint8 rarity;        // N=1, R=2, SR=3, SSR=4, UR=5
        uint8 level;         // 1-80
        uint8 stars;         // 1-7
        uint8 breakthrough;  // 0-8
        uint16 charm;        // Charm value
        uint32 experience;   // Experience points
        uint32 fatigue;      // Fatigue value
        bytes32 attributes;  // Attribute data
    }
    
    mapping(uint256 => Hero) public heroes;
    mapping(address => uint256[]) public userHeroes;
    
    function mintHero(address to, uint8 rarity) external returns (uint256);
    function upgradeHero(uint256 tokenId, uint32 exp) external;
    function addFatigue(uint256 tokenId, uint32 amount) external;
    function recoverFatigue(uint256 tokenId, uint32 amount) external;
}

3. StakingPool.sol - Staking Pool Contract

contract StakingPool {
    struct StakeInfo {
        uint256 amount;      // Staked amount
        uint256 timestamp;   // Staking time
        uint256 lockPeriod;  // Lock-up period
        uint256 rewardDebt;  // Reward debt
    }
    
    mapping(address => StakeInfo) public stakes;
    
    function stake(uint256 amount, uint256 lockPeriod) external;
    function unstake(uint256 amount) external;
    function claimRewards() external returns (uint256);
    function getRewardRate() external view returns (uint256);
}

🔐 Security Mechanism Design

Multiple Security Guarantees

1. Access Control: Based on OpenZeppelin's AccessControl

2. Re-entrancy Protection: Protected by ReentrancyGuard

3. Integer Overflow Protection: Use of SafeMath library

4. Pause Mechanism: Contract pausing in emergencies

5. Multi-sig Wallet: Critical operations require multiple signatures

Contract Upgrade Strategy

// Proxy contract pattern
contract MythoriaProxy {
    address public implementation;
    address public admin;
    
    modifier onlyAdmin() {
        require(msg.sender == admin, "Only admin");
        _;
    }
    
    function upgrade(address newImplementation) external onlyAdmin {
        implementation = newImplementation;
        emit Upgraded(newImplementation);
    }
}
