Blockchain-Based Online Gaming with Decentralized Leaderboards

Objective

To create a fair and transparent online gaming platform that uses blockchain technology to store player scores, achievements, and leaderboards in a tamper-proof, decentralized manner—enhancing trust, competition, and rewards.

Key Features

Decentralized Leaderboards: Player scores and ranks stored immutably on the blockchain.

Smart Contract-Based Game Logic: Ensures transparency in rewards, point calculations, and event triggers.

Tokenized Rewards: Players earn crypto tokens or NFTs for in-game achievements or rankings.

Anti-Cheating Mechanisms: Blockchain validation prevents fraudulent score manipulation.

Ownership of In-Game Assets: Players can own, trade, or sell NFTs representing game items or characters.

Technologies Used

Blockchain Platforms: Ethereum, Polygon, or Solana

Smart Contract Language: Solidity (Ethereum/Polygon), Rust (Solana)

Game Engine: Unity or Unreal Engine with Web3 integration

NFT Standards: ERC-721 or ERC-1155 for in-game assets

Frontend: React.js or Phaser.js (for browser-based games)

Backend: Node.js, Express.js (for off-chain processing)

Wallet Integration: MetaMask, WalletConnect, or Phantom (for Solana)

How It Works

User Registration: Players connect their crypto wallets to authenticate.

Game Interaction: Users play the game normally (solo or multiplayer).

Score Submission: Scores are submitted and verified via smart contracts.

Leaderboard Update: Verified scores are posted on the blockchain in real time.

Reward Distribution: Top players receive crypto tokens or NFT items based on leaderboard ranking.

Asset Management: Players can trade or use blockchain-based items across games or marketplaces.

Benefits
