Reaction Time Game
Build an arcade-style reaction game that showcases RISE's 3ms transaction confirmations
Introduction
In this tutorial, you'll build an interactive reaction time game that proves blockchain doesn't have to be slow. The game challenges players to test their reflexes while simultaneously recording each click on the blockchain, showcasing RISE's groundbreaking 3ms transaction pre-confirmations.
What You'll Build
An arcade-style game with:
- 5-round reaction time test with millisecond precision
- Realtime blockchain transaction recording for each click
- Pre-signed transaction pool for zero-latency gameplay
- Performance metrics comparing reaction time vs transaction time
- Retro arcade UI with dynamic color transitions
What You'll Learn
- How to build latency-sensitive applications on blockchain
- Using
eth_sendRawTransactionSyncfor synchronous confirmations - Pre-signing transaction batches for optimal performance
- Transaction pool management with background refilling
- Measuring blockchain overhead with precision timing
- Building game state machines in React
The Secret Sauce: 3ms Confirmations
Traditional blockchains take 100-300ms+ just to confirm transactions. too slow for realtime gaming. RISE's synchronous transactions confirm in ~3ms, making blockchain fast enough for arcade games, trading bots, and other latency-critical apps.
This game proves it: Your total response time (reaction + blockchain) will be only ~3ms slower than your raw reaction time!
Prerequisites
Before starting, make sure you have:
- Node.js 18+ installed
- Basic knowledge of React and Next.js
- Understanding of TypeScript
- A burner wallet private key for testnet (we'll generate one)
This tutorial uses a burner wallet (exposed private key) for simplicity. Never use real funds with this pattern!
