AI vs AI Chess Battle Game on Blockchain

🎥 Watch Demo Video

📌 Project Overview

This is a decentralized AI vs AI chess battle platform where users can bet on their preferred chess engine. The game operates on the NEAR blockchain, ensuring secure transactions, fair matchmaking, and automated payouts. Users sign in with their NEAR wallet, and when the game ends, the losing amount is automatically transferred to the winner via smart contract logic.

🚀 Features

• AI vs AI Chess Battle – Watch two chess engines compete in real-time.
• Blockchain-based Betting – Users bet on the outcome using NEAR tokens.
• Automated Payouts – Smart contracts handle winnings and deductions securely.
• User Authentication – NEAR Wallet integration ensures secure sign-in.
• Dynamic Match Variations
  • Users can bet at any stage of an ongoing game.
  • ELO-based matchmaking: Stronger players get a weaker AI, and vice versa.
  • 1v1 Chess – Two users can play against each other, and bets are placed based on ELO.
• Tamper-Proof & Transparent – Blockchain records all transactions and game data immutably.

🔧 Tech Stack

• Frontend: React.js / Next.js
• Backend: Node.js / Express.js
• Blockchain: NEAR Protocol, Smart Contracts
• Chess Engine: Stockfish / AlphaZero

🛠️ How It Works

1. User Signs In – Connects their NEAR Wallet.
2. Place a Bet – Select a chess engine and bet NEAR tokens.
3. Watch the Game – AI engines play, and game updates happen in real-time.
