🎮 Play Live Demo • 📖 Documentation • 🚀 Deployment Guide • 🏆 Hackathon Submission

🌍 The Problem We're Solving

Africa has the world's youngest population — 70% under 30 years old — yet faces critical challenges:

High Youth Unemployment: Over 60% in some countries [UNICEF, 2023]
Limited Blockchain Literacy: Despite growing adoption, misinformation and lack of accessible education prevent many from benefiting
Unrewarded Gaming: Millions of African gamers play without earning real-world value
Cultural Underrepresentation: African culture and art remain underrepresented in global gaming ecosystems

The opportunity is massive: Africa's gaming market is projected to reach $1 billion by 2024, with mobile gaming leading the charge.

💡 Our Solution: Mindera Run

Mindera Run turns play into empowerment by combining entertainment, education, and economic opportunity:

🎮 Gameplay

Run, jump, and dodge obstacles through 3 beautiful stages
Collect coins and power-ups
Progressive difficulty with African-inspired visuals

📚 Learning

Gamified blockchain education:

Answer questions about Hedera blockchain to advance levels
Learn about HTS, HSCS, consensus mechanisms, and more
Knowledge walls that unlock new stages

💰 Rewards

🔗 Hedera Services Integration

Hedera Token Service (HTS) 💰

We leverage HTS to create a complete token economy within the game:

QuestCoin - Fungible Token

// Token Creation (scripts/createTokens.js)
const questCoinTx = new TokenCreateTransaction()
  .setTokenName("QuestCoin")
  .setTokenSymbol("QC")
  .setTokenType(TokenType.FungibleCommon)
  .setDecimals(2)
  .setInitialSupply(1000000)
  .setSupplyType(TokenSupplyType.Infinite)
  .setTreasuryAccountId(operatorId)
  .setSupplyKey(operatorKey);

How We Use It:

Token ID: 0.0.7158216 (QuestCoin)
Minting: Treasury account mints tokens when players complete stages
Distribution: 20 tokens (Stage 1), 50 tokens (Stage 2), 100 tokens (Stage 3)
Transfers: Tokens transferred directly to player wallets
Balance Queries: Real-time balance checks via Mirror Node API

Badge NFTs - Non-Fungible Tokens

// NFT Token Creation
const badgeNFTTx = new TokenCreateTransaction()
  .setTokenName("Mindora Runner Badges")
  .setTokenSymbol("MRB")
  .setTokenType(TokenType.NonFungibleUnique)
  .setSupplyType(TokenSupplyType.Infinite)
  .setTreasuryAccountId(operatorId)
  .setSupplyKey(operatorKey)
  .setMetadataKey(operatorKey);

How We Use It:

Token ID: 0.0.7158217 (Badge NFTs)
Metadata: Each NFT contains JSON metadata with badge info, stage, and timestamp
Minting: Unique NFT minted for each stage completion
African Art: NFTs feature African-inspired designs (Explorer, Adventurer, Master badges)
Ownership: Players own NFTs in their wallets, can trade in marketplace

HTS Implementation in Code

// frontend/src/services/hederaService.ts

// Mint QuestCoin tokens
async mintQuestCoins(amount: number, recipientAccountId: string) {
  const mintTx = new TokenMintTransaction()
    .setTokenId(this.questCoinTokenId)
    .setAmount(amount * 100); // 2 decimal places
  
  const mintSubmit = await mintTx.execute(this.client);
  
  // Transfer to player
  const transferTx = new TransferTransaction()
    .addTokenTransfer(this.questCoinTokenId, this.operatorId, -amount * 100)
    .addTokenTransfer(this.questCoinTokenId, recipientAccountId, amount * 100);
  
  await transferTx.execute(this.client);
}

// Mint NFT Badge
async mintNFTBadge(badgeType: string, recipientAccountId: string) {
  const metadata = Buffer.from(JSON.stringify({
    name: badgeType,
    game: "Mindora Runner",
    stage: stageNumber,
    date: new Date().toISOString(),
    culture: "African-inspired"
  }));
  
  const nftMintTx = new TokenMintTransaction()
    .setTokenId(this.nftTokenId)
    .setMetadata([metadata]);
  
  const mintSubmit = await nftMintTx.execute(this.client);
  
  // Transfer NFT to player
  const transferTx = new TransferTransaction()
    .addNftTransfer(this.nftTokenId, serialNumber, this.operatorId, recipientAccountId);
  
  await transferTx.execute(this.client);
}

Hedera Smart Contract Service (HSCS) 🧠

We use HSCS to store game state and logic on-chain:

Smart Contract Deployment

// Smart-contract/MindoraRunnerFinal.sol
contract MindoraRunnerFinal {
    struct Player {
        string username;
        bool isRegistered;
        uint256 currentStage;
        uint256 totalScore;
        uint256 inGameCoins;
        uint256 questTokensEarned;
        uint256 totalGamesPlayed;
        uint256 registrationTime;
    }
    
    mapping(address => Player) public players;
    mapping(uint256 => GameSession[]) public stageLeaderboards;
    mapping(address => mapping(uint256 => bool)) public tokensClaimed;
    mapping(address => mapping(uint256 => bool)) public nftClaimed;
}

How We Use It:

Contract ID: 0.0.7172114 (MindoraRunnerFinal)
Player Registration: On-chain player profiles with username and stats
Score Tracking: All game sessions stored permanently on blockchain
Leaderboards: Stage-specific and general leaderboards
Claim Tracking: Prevents duplicate token/NFT claims
Reward Calculation: Smart contract calculates token rewards based on stage

Contract Interactions

// frontend/src/components/ContractManager.tsx

// Register player on-chain
const registerPlayer = async (username: string) => {
  const tx = new ContractExecuteTransaction()
    .setContractId(contractAddress)
    .setGas(100000)
    .setFunction('registerPlayer', new ContractFunctionParameters()
      .addString(username)
    );
  
  await tx.execute(client);
};

// Save game session to blockchain
const saveGameSession = async (stage, score, coins, questions, completed) => {
  const tx = new ContractExecuteTransaction()
    .setContractId(contractAddress)
    .setGas(200000)
    .setFunction('saveGameSession', new ContractFunctionParameters()
      .addUint256(stage)
      .addUint256(score)
      .addUint256(coins)
      .addUint256(questions)
      .addBool(completed)
    );
  
  await tx.execute(client);
};

// Query player data from contract
const getPlayer = async (address: string) => {
  const query = new ContractCallQuery()
    .setContractId(contractAddress)
    .setGas(50000)
    .setFunction('getPlayer', new ContractFunctionParameters()
      .addAddress(address)
    );
  
  const result = await query.execute(client);
  return decodePlayerData(result);
};

Hedera Consensus Service (HCS) 📨

We use HCS for transparent game event logging:

// scripts/createHCSTopic.js
const topicCreateTx = new TopicCreateTransaction()
  .setTopicMemo("Mindora Runner Game Events")
  .setAdminKey(operatorKey)
  .setSubmitKey(operatorKey);

// Log game events
const logEvent = async (eventData) => {
  const message = JSON.stringify({
    event: "stage_completed",
    player: playerAddress,
    stage: stageNumber,
    score: finalScore,
    timestamp: new Date().toISOString()
  });
  
  const messageTx = new TopicMessageSubmitTransaction()
    .setTopicId(gameEventsTopic)
    .setMessage(message);
  
  await messageTx.execute(client);
};

How We Use It:

Topic ID: 0.0.6920083 (Game Events)
Event Logging: All major game events logged to HCS
Transparency: Public verification of achievements
Anti-Cheat: Immutable proof of game sessions
Analytics: Query topic messages for game statistics
