```solidity
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
    }
}
```

## Smart Contract Architecture & Functions

### Multi-Layer Token Architecture

#### Layer 1: Core Token Infrastructure

```solidity
// Enhanced ERC20 with advanced features
contract DTA is ERC20, ERC20Burnable, ERC20Pausable, AccessControl, ReentrancyGuard {
    // Core constants
    uint256 public constant TOTAL_SUPPLY = 1_000_000_000 * 10**4; // 1B tokens, 4 decimals
    uint256 public constant MAX_STAKE_DURATION = 365 days;
    uint256 public constant MIN_PROPOSAL_THRESHOLD = 1_000_000 * 10**4; // 1M DTA
    
    // Multi-dimensional staking tiers
    enum StakingTier { BRONZE, SILVER, GOLD, PLATINUM, DIAMOND }
    
    struct StakingInfo {
        uint256 stakedAmount;
        uint256 stakingStartTime;
        StakingTier tier;
        uint256 pendingRewards;
        bool isActive;
    }
}
```

#### Layer 2: Digital Twin Integration

```solidity
// Future implementation for twin services
struct DigitalTwin {
    bytes32 twinId;              // Unique twin identifier
    address owner;               // Twin owner
    uint256 stakedAmount;        // Required stake for twin
    uint256 dataQualityScore;    // AI-assessed data quality
    uint256 serviceRevenue;      // Generated revenue in DTA
    TwinType twinType;           // Industrial, Medical, Smart City, etc.
    bool isActive;               // Twin operational status
}

enum TwinType { INDUSTRIAL, MEDICAL, SMART_CITY, AGRICULTURE, AUTOMOTIVE, ENERGY }
```

#### Layer 3: AI & Data Economy

```solidity
// AI service marketplace integration
struct AIService {
    bytes32 serviceId;           // Service identifier
    address provider;            // AI service provider
    uint256 pricePerQuery;      // Cost in DTA tokens
    uint256 qualityRating;      // Community rating
    ServiceType serviceType;     // ML, Vision, NLP, etc.
    bool isVerified;            // Platform verification
}

enum ServiceType { MACHINE_LEARNING, COMPUTER_VISION, NATURAL_LANGUAGE, PREDICTIVE_ANALYTICS }
```

### Core Smart Contract Functions

#### Enhanced ERC20 Functions

```solidity
function transfer(address to, uint256 amount) external returns (bool) {
    // Standard transfer with additional logging for analytics
    _transfer(_msgSender(), to, amount);
    emit TransferAnalytics(_msgSender(), to, amount, block.timestamp);
    return true;
}

function transferWithData(address to, uint256 amount, bytes calldata data) external returns (bool) {
    // Transfer with metadata for IoT and AI applications
    _transfer(_msgSender(), to, amount);
    emit DataTransfer(_msgSender(), to, amount, data, block.timestamp);
    return true;
}
```

#### Advanced Staking System

```solidity
function stake(uint256 amount, uint8 tier) external nonReentrant {
    require(amount >= getMinStakeAmount(tier), "Insufficient stake amount");
    require(tier <= uint8(StakingTier.DIAMOND), "Invalid staking tier");
    
    StakingInfo storage info = stakingInfo[_msgSender()];
    require(!info.isActive, "Already staking");
    
    _transfer(_msgSender(), address(this), amount);
    
    info.stakedAmount = amount;
    info.stakingStartTime = block.timestamp;
    info.tier = StakingTier(tier);
    info.isActive = true;
    
    totalStaked += amount;
    emit StakeCreated(_msgSender(), amount, tier, block.timestamp);
}

function calculateRewards(address user) public view returns (uint256) {
    StakingInfo memory info = stakingInfo[user];
    if (!info.isActive) return 0;
    
    uint256 stakingDuration = block.timestamp - info.stakingStartTime;
    uint256 baseAPY = getAPYForTier(info.tier);
    
    // Bonus multipliers for ecosystem participation
    uint256 twinBonus = getTwinParticipationBonus(user);
    uint256 governanceBonus = getGovernanceParticipationBonus(user);
    uint256 dataBonus = getDataContributionBonus(user);
    
    uint256 totalAPY = baseAPY + twinBonus + governanceBonus + dataBonus;
    
    return (info.stakedAmount * totalAPY * stakingDuration) / (365 days * 100);
}
```

Multi-Utility Staking Benefits:

| Lock Period  | APY Rate | Primary Use Case         | Ecosystem Benefits                               |
| ------------ | -------- | ------------------------ | ------------------------------------------------ |
| 30-89 days   | 8% APY   | Data Contribution        | Quality data validation, IoT device registration |
| 90-179 days  | 10% APY  | AI Model Training        | GPU resource allocation, model validation        |
| 180-364 days | 12% APY  | Digital Twin Services    | Twin hosting, simulation processing              |
| 365+ days    | 15% APY  | Governance Participation | Long-term ecosystem development                  |

    string title;
    string description;
    uint256 votingStart;
    uint256 votingEnd;
    uint256 forVotes;
    uint256 againstVotes;
    uint256 abstainVotes;
    bool executed;
    bool cancelled;
    // Enhanced governance tracking
    mapping(address => bool) hasVoted;
    mapping(address => uint8) votes; // 0=Against, 1=For, 2=Abstain
}
```

Next-Generation Governance:

```solidity
function propose(
    string calldata title,
    string calldata description,
    address[] calldata targets,
    uint256[] calldata values,
    bytes[] calldata calldatas
) external returns (uint256) {
    require(balanceOf(_msgSender()) >= MIN_PROPOSAL_THRESHOLD, "Insufficient DTA balance");
    require(targets.length == values.length && targets.length == calldatas.length, "Proposal arrays mismatch");
    
    uint256 proposalId = hashProposal(targets, values, calldatas, keccak256(bytes(description)));
    
    Proposal storage proposal = proposals[proposalId];
    require(proposal.id == 0, "Proposal already exists");
    
    proposal.id = proposalId;
    proposal.proposer = _msgSender();
    proposal.title = title;
    proposal.description = description;
    proposal.targets = targets;
    proposal.values = values;
    proposal.calldatas = calldatas;
    proposal.startTime = block.timestamp;
    proposal.endTime = block.timestamp + VOTING_PERIOD;
    proposal.state = ProposalState.ACTIVE;
    
    emit ProposalCreated(proposalId, _msgSender(), title, description);
    return proposalId;
}

function voteWithReason(uint256 proposalId, bool support, string calldata reason) external {
    Proposal storage proposal = proposals[proposalId];
    require(proposal.state == ProposalState.ACTIVE, "Proposal not active");
    require(block.timestamp <= proposal.endTime, "Voting period ended");
    require(!hasVoted[proposalId][_msgSender()], "Already voted");
    
    uint256 votingPower = getVotingPower(_msgSender());
    require(votingPower > 0, "No voting power");
    
    if (support) {
        proposal.forVotes += votingPower;
    } else {
        proposal.againstVotes += votingPower;
    }
    
    hasVoted[proposalId][_msgSender()] = true;
    emit VoteCast(_msgSender(), proposalId, support, votingPower, reason);
}
```

#### Tokenomics & Burn Mechanism

```solidity
function burn(uint256 amount) public override {
    super.burn(amount);
    
    // Deflationary mechanism with ecosystem rewards
    uint256 rewardAmount = (amount * BURN_REWARD_RATE) / 100;
    _distributeEcosystemRewards(rewardAmount);
    
    emit TokensBurned(_msgSender(), amount, rewardAmount, block.timestamp);
}

function autoburn() external {
    require(hasRole(AUTOBURN_ROLE, _msgSender()), "Not authorized for autoburn");
    
    // Automatic burn of inactive tokens
    uint256 burnAmount = calculateAutoburnAmount();
    if (burnAmount > 0) {
        _burn(address(this), burnAmount);
        emit AutoburnExecuted(burnAmount, block.timestamp);
    }
}
```

### Integration APIs for Ecosystem Development

#### Digital Twin Service Integration

```solidity
function registerDigitalTwin(
    bytes32 twinId,
    TwinType twinType,
    uint256 requiredStake
) external returns (bool) {
    require(requiredStake >= MIN_TWIN_STAKE, "Insufficient stake");
    require(balanceOf(_msgSender()) >= requiredStake, "Insufficient DTA balance");
    
    _transfer(_msgSender(), address(this), requiredStake);
    
    digitalTwins[twinId] = DigitalTwin({
        twinId: twinId,
        owner: _msgSender(),
        stakedAmount: requiredStake,
        dataQualityScore: 100, // Initial score
        serviceRevenue: 0,
        twinType: twinType,
        isActive: true
    });
    
    emit TwinRegistered(twinId, _msgSender(), twinType, requiredStake);
    return true;
}

function payForTwinService(bytes32 twinId, uint256 amount) external returns (bool) {
    DigitalTwin storage twin = digitalTwins[twinId];
    require(twin.isActive, "Twin not active");
    require(balanceOf(_msgSender()) >= amount, "Insufficient DTA balance");
    
    _transfer(_msgSender(), twin.owner, amount);
    twin.serviceRevenue += amount;
    
    // Service usage bonus for twin owner
    uint256 bonus = (amount * TWIN_SERVICE_BONUS) / 100;
    _mint(twin.owner, bonus);
    
    emit TwinServicePayment(twinId, _msgSender(), twin.owner, amount, bonus);
    return true;
}
```

#### Data Economy Functions

```solidity
function rewardDataContribution(
    address contributor, 
    uint256 amount, 
    bytes32 dataHash,
    uint8 qualityScore
) external onlyDataOracle {
    require(qualityScore >= MIN_DATA_QUALITY, "Data quality too low");
    
    // Quality-based reward multiplier
    uint256 rewardMultiplier = qualityScore > 90 ? 150 : qualityScore > 70 ? 120 : 100;
    uint256 finalReward = (amount * rewardMultiplier) / 100;
    
    _mint(contributor, finalReward);
    
    dataContributions[contributor] += finalReward;
    dataHashes[dataHash] = contributor;
    
    emit DataContributionRewarded(contributor, finalReward, dataHash, qualityScore);
}
```

#### AI Service Marketplace

```solidity
function listAIService(
    bytes32 serviceId,
    uint256 pricePerQuery,
    ServiceType serviceType,
    string calldata description
) external returns (bool) {
    require(balanceOf(_msgSender()) >= AI_SERVICE_LISTING_FEE, "Insufficient listing fee");
    
    _transfer(_msgSender(), treasury, AI_SERVICE_LISTING_FEE);
    
    aiServices[serviceId] = AIService({
        serviceId: serviceId,
        provider: _msgSender(),
        pricePerQuery: pricePerQuery,
        qualityRating: 100, // Initial rating
        serviceType: serviceType,
        isVerified: false
    });
    
    emit AIServiceListed(serviceId, _msgSender(), pricePerQuery, serviceType);
    return true;
}

function useAIService(bytes32 serviceId, uint256 queries) external returns (bool) {
    AIService storage service = aiServices[serviceId];
    require(service.provider != address(0), "Service not found");
    
    uint256 totalCost = service.pricePerQuery * queries;
    require(balanceOf(_msgSender()) >= totalCost, "Insufficient DTA balance");
    
    // Payment distribution: 90% to provider, 10% to platform
    uint256 providerAmount = (totalCost * 90) / 100;
    uint256 platformFee = totalCost - providerAmount;
    
    _transfer(_msgSender(), service.provider, providerAmount);
    _transfer(_msgSender(), treasury, platformFee);
    
    emit AIServiceUsed(serviceId, _msgSender(), service.provider, totalCost, queries);
    return true;
}
```

### Economic Model & Tokenomics

#### Supply & Distribution Strategy

Total Supply: 1,000,000,000 DTA (1 Billion tokens)\
Decimal Places: 4 (for micro-transaction precision)

Distribution Allocation:

* Ecosystem Rewards (30%): 300,000,000 DTA
  * Staking Rewards Pool: 120,000,000 DTA (12%)
  * Digital Twin Incentives: 80,000,000 DTA (8%)
  * AI Service Provider Rewards: 60,000,000 DTA (6%)
  * Data Contribution Rewards: 40,000,000 DTA (4%)
* Treasury & Partnerships (22%): 220,000,000 DTA
* Burn & Reserve Pool (13.7%): 137,000,000 DTA
* BIVE Token Swap (11%): 110,000,000 DTA
* Team & Advisors (10%): 100,000,000 DTA
* Community DAO (10%): 100,000,000 DTA
* BIVE Bonus (3.3%): 33,000,000 DTA

#### Value Accrual Mechanisms

1. Utility-Driven Demand

```solidity
// Transaction types that create token demand
enum TransactionType {
    TWIN_REGISTRATION,      // 10,000 DTA minimum stake
    AI_SERVICE_PAYMENT,     // Variable based on service
    DATA_MARKETPLACE,       // 0.1-1000 DTA per dataset
    GOVERNANCE_PROPOSAL,    // 1,000,000 DTA proposal threshold
    PREMIUM_STAKING         // Higher APY for longer commitments
}
```

2. Deflationary Pressure

* Service Burns: 5% of AI service payments burned
* Quality Control: Poor service provider penalties burned
* Governance Burns: Failed proposal deposits burned
* Ecosystem Optimization: Automatic burns based on network health

3. Staking Economics

Staking Tier System:

| Tier     | Minimum Stake | Base APY | Max APY (w/bonuses) |
| -------- | ------------- | -------- | ------------------- |
| Bronze   | 1,000         | 8%       | 12%                 |
| Silver   | 10,000        | 10%      | 15%                 |
| Gold     | 50,000        | 12%      | 18%                 |
| Platinum | 100,000       | 15%      | 22%                 |
| Diamond  | 500,000       | 18%      | 25%                 |

Bonus Multipliers:

* Digital Twin Participation: +20% APY
* Data Contribution Quality: +15% APY
* Governance Voting: +10% APY
* AI Service Provision: +25% APY

#### Revenue Sharing Model

```solidity
struct RevenueDistribution {
    uint256 stakeholders;      // 60% to stakers
    uint256 development;       // 25% to ecosystem development
    uint256 treasury;          // 10% to DAO treasury
    uint256 burn;              // 5% permanently burned
}
```

    require(amount > 0, "DTA: Amount must be greater than 0");
    require(amount <= balanceOf(_msgSender()), "DTA: Insufficient balance");
    require(tier <= uint8(StakingTier.DIAMOND), "DTA: Invalid staking tier");
    require(amount >= getMinStakeAmount(tier), "DTA: Amount below minimum for tier");
    
    StakingInfo storage info = stakingInfo[_msgSender()];
    require(!info.isActive, "DTA: Already staking");
    
    // Safe state updates...
}
```

    _pause();
}

function unpause() external onlyRole(PAUSER_ROLE) {
    _unpause();
}

// Blacklist management for security
function addToBlacklist(address account) external onlyRole(ADMIN_ROLE) {
    blacklist[account] = true;
    emit BlacklistUpdated(account, true);
}
```

// Check token balance
async function getBalance(userAddress) {
    const balance = await contract.methods.balanceOf(userAddress).call();
    return parseFloat(balance) / 10000; // Convert from 4 decimals
}

// Transfer tokens
async function transferTokens(fromAddress, toAddress, amount, privateKey) {
    const amountWei = (amount * 10000).toString(); // Convert to 4 decimals
    
    const transaction = {
        to: contractAddress,
