🎲 ChainBet — Decentralized Betting on Linera

A fast, scalable, and transparent prediction game powered by Linera Protocol. Bet on outcomes, challenge friends, and let the chain decide — all on-chain, all fair.

---

🚀 Overview

ChainBet is a decentralized betting dApp built on the Linera Protocol, combining:

• 🦀 Rust smart contracts for secure, on-chain logic
• ⚡ TypeScript frontend for an elegant, reactive user experience
• 🔗 Linera’s parallel chains for scalable betting without gas wars

---

🧠 Core Idea

Each player places a bet on a specific outcome (e.g., a coin toss, sports result, or community event). The system:

1. Locks each bet on-chain.
2. Resolves the result using deterministic or oracle-fed data.
3. Distributes winnings automatically.

Fair, transparent, and provable.
