Predict

Predict is a free-to-play and fun prediction game for humans on World. Creators pay a bounty to ask a question, which gets paid to the user who guesses closest to the actual answer. But it's more than just a fun activity. Creators can ask any question and get crowd-sourced wisdom before the event unfolds. This is based on the idea of the "wisdom of the crowd", where the median of many people's guesses is an accurate indicator of the true answer. By gating each guess to one human, we can be sure that these are fair polls and not manipulated by bots. Meanwhile, humans have a fair shot at the bounty as they are not crowded by bots and alt accounts.

This project uses World's MiniKit along with next.js to create a Mini App. Ngrok was used for testing, but the final product is hosted on Vercel. World ID proofs are used on the smart contract level to guarantee orb-verified interactions. The main smart contract is deployed using Foundry on World mainnet. Blockscout is used as the explorer.
