PSL Integrity Shield
A blockchain-based system for verifying data integrity, built to provide tamper-proof verification records.
About the Project
Built for the Entangled Hackathon 2026 on the WireFluid Network: an on-chain protocol for detecting and deterring match-fixing in the Pakistan Super League.
Ball-by-ball events are hashed on-chain, predictions use a commit-reveal scheme, and the community stakes tokens to flag suspicious matches.
What I Built
Three Solidity smart contracts — MatchOracle, PredictionEngine and AnomalyTracker — with a React and Vite frontend wired up through ethers.js and MetaMask.
The protocol tracks reporter trust scores, certifies clean matches and surfaces a season integrity dashboard. The contract suite ships with 38 passing tests.
Why It Matters
Match-fixing is a trust problem, and trust problems are what public ledgers are genuinely good for. The real design work was in the incentives: making honest reporting profitable and false flags expensive.
