Outcome

A decentralized prediction market platform built on Mantle Network where users can buy yes/no shares to bet on various flight-related events, such as delays, cancellations, on-time arrivals, early arrivals, airlines with the most flights, airports with the most traffic, worst airlines, and more. (Note: The current model focuses only on flight delays, with plans to expand to these additional event types.) Built with Next.js, Bun.js, and Solidity, Outcome combines AI-driven flight data with trustless blockchain settlement.

• Prediction Markets: Participate in decentralized markets for flight arrival status.

• AI Risk Assessment: Integrated Llama 3.1 analysis via Groq for real-time trading signals and flight risk reports.

• Real-time Aviation Data: Automated flight tracking and market initialization powered by the AviationStack API.

• Hybrid AMM: Sophisticated Logarithmic Market Scoring Rule (LMSR) for liquidity pricing, paired with a fair cost-based payout mechanism.

• Mantle Network: High-performance, low-fee trading secured by Ethereum.

• Connect with Ease: Seamless wallet integration via Particle Network, supporting both social and traditional EOA logins.

How it's Made

Smart Contracts

• Solidity Contracts: Core logic for decentralized flight prediction markets.

• LMSR Pricing Mechanism: Uses the Logarithmic Market Scoring Rule (LMSR) to enable liquidity and dynamic pricing even with low volume.

• Mantle Deployment: Deployed on Mantle Sepolia for ultra-low fees and high-performance execution.

Backend & Resolution

• Decentralized Oracle: Uses an automated resolver to settle markets based on real-world flight data.

• Aviation Data Integration: Fetches real-time flight statuses from professional aviation APIs (Aviation Edge).

• On-Chain Resolution: Trustless resolution directly on the Mantle blockchain, ensuring payouts are secure and immutable.

Frontend & UX

• Next.js 16: Built with the latest Next.js App Router for high performance and SEO optimization.

• Web3 Integration: Powered by Wagmi and Viem for seamless blockchain interactions.

• Particle Network: Integrated social logins (Google, Twitter, Email) to provide a non-crypto-native user experience.

• Modern UI: Styled with Tailwind CSS and Framer Motion for a premium, responsive feel.
