Problem
Consumers often receive promotional giveaways and discount offers that are difficult to claim, while brands struggle with fraud and inefficient distribution of rewards to genuine customers.
Solution
ZKPuzzle is a mobile app that combines end‑to‑end encrypted group chat with daily zero‑knowledge‑verified puzzles. Users solve a variety of free puzzles each morning, and each completed game is cryptographically proven to be performed by a real human. Brands fund giveaways, gift cards, and discount codes that are routed directly to verified players, ensuring that every dollar of promotional spend reaches an actual user. Earned rewards are paid out in USD to a ZKPuzzle wallet, and additional earnings are available through referrals, content creation, and redeeming unused gift cards. The platform’s low‑cost zero‑knowledge fraud prevention creates a transparent, human‑only rewards ecosystem.
