Problem Statement

ChallengeMe is a community-driven, Web3-powered app designed for tight-knit groups of friends, clubs, or communities. It transforms personal challenges into gamified experiences, motivating individuals to achieve their goals through collective support and friendly betting. 💪🎯🌟🌟🌟 Key Features:🎮 Personal Challenges with Gamified Betting • Users create personal challenges (e.g., “I will exercise every day for 30 days” or “I won’t drink alcohol for 2 months”). • Friends bet on the challenge’s success or failure by choosing between two options: “CAN” or “CAN’T.” • Stakes are placed, adding fun pressure to the challenge creator while keeping the group engaged.🎲 Outcome Resolution with Random Group Verifier • Once the challenge ends, the creator submits evidence (e.g., photos, videos) to prove if they met their goal. • A Random Group Verifier is selected to review the evidence and finalize the result, ensuring transparency and fairness. • The verifier’s decision distributes the stakes: winners receive their share of the pooled bets. • MOST IMPORTANTLY: This is a tight-knit group, and no one wants to lose their reputation, so cheating is highly unlikely. 🔒🧑‍🤝‍🧑🌟🌟🌟🌐 Web3 Integration for Security and Accessibility • Web3Auth simplifies onboarding, allowing users to create and manage accounts without advanced blockchain knowledge. • World ID ensures each participant is unique, preventing duplicate accounts and fostering trust.🌟🌟🌟🚀 Motivation and Accountability • The app’s primary goal is to encourage personal growth and accountability in a supportive environment. • The gamified structure not only motivates challenge creators but also keeps supporters engaged and invested.🌟🌟🌟🌱 Community Focus • Unlike speculative markets like Polymarket, ChallengeMe emphasizes real-world personal growth and accountability within small, trusted communities. • It’s about mutual encouragement and shared success, not profit-driven motives.🌟🌟🌟🛡️ Dispute Mechanism and Transparency (Future Plans) • If the verifier’s decision is contested, the group can initiate a secondary review or vote. • A Random Number Generator (RNG) from a trusted partner ensures impartiality when necessary.How It WorksUser Onboarding: A smooth Web2 experience integrates with Web3 for seamless onboarding and ID verification.
