Project Description

Bots are not fun to play with. But with financial incentives in P2E games, it's profitable to run them and siphon valuable rewards from honest players. This project creates a meta-game that can be layered on top of any other blockain game to weed out bots from competition. It is a simple quiz game where users should answer questions. Since blockhain is public, we use zk-SNARKs, so no one could copy your answer. Player show on-chain proof that they know answer for question, but don't reveal it.

How it's Made

We use circom and snarkjs for zero knowledge proofs. Chainlink for the randomness in questions picked and moralis + nftPort on the frontend side for our sample game. It's interesting how we implement ranked questions, they constantly moving in array. The more their win rate deviate from 80%, the further away they are in the array
