FitterCoin — get rewarded for getting fit

FitterCoin is a “workout-to-earn” fitness platform that pays people in crypto for doing real workouts. It combines personalized AI training, live verified contests, and optional spectator betting—so staying active is fun, social, and rewarding.

What it does

Personalized AI challenges: After sign-in, FitterCoin tailors daily and weekly workouts to each user’s age, gender, and location (e.g., an 18-year-old might see higher-intensity sessions than a beginner in their 40s). These plans adapt over time based on performance.

Live, verifiable workouts: Using the phone/laptop camera, our real-time motion model detects exercises like push-ups and squats, counts clean reps, checks range of motion, and timestamps sets—so only genuine effort gets rewarded.

Contests you can join or create: Jump into public leaderboards (e.g., max push-ups/squats in 5 minutes), set up private challenges with friends, or run solo “personal contests” to beat your PRs.

Stake-to-enter, win rewards: To enter a contest, users stake an amount. Smart contracts escrow stakes, verify winners from the real-time proof, and pay out automatically. Winners earn both the prize pool and ongoing FitterCoin rewards for consistent training.

Betting for spectators (optional): View player profiles, past results, and live streams, then stake on a contestant you believe will win. Follow the match in real time and settle instantly after results are validated.

Trust, identity, and personalization

We’ve integrated Self for authentication and validated attributes (age, gender, location). This powers smarter, safer matchmaking and ensures fairness, reduces smurfing/Sybil abuse, and lets us tune challenge difficulty to local contexts (e.g., climate/altitude).

Under the hood

On-chain: Smart contracts deployed on the Cirtea testnet; transactions and rewards use cBTC.

Fairness & anti-cheat: Live pose detection + liveness checks; rep validation (form thresholds, tempo/range checks); tamper-resistant session proofs; on-chain settlement.

Profiles & history: Public stats (if opted in), win/loss, best performances, and badges—so skill and consistency are visible and meaningful.

Why it matters

Most fitness apps struggle to keep people motivated. FitterCoin turns effort into immediate, provable value—earn by moving, compete when you want, and make training social with friendly stakes or spectator action. It’s fitness that finally pays you back.

We built FitterCoin by stitching together AI, Web3, and computer vision into one seamless experience.

Identity & fairness: We integrated Self SDK for age, gender, and location verification—this powers personalized challenges and prevents Sybil abuse.

On-chain logic: Smart contracts are deployed on Citrea testnet (with Sepolia fallback), handling staking, contest payouts, and rewards transparently in cBTC.

Computer vision: Using OpenCV + MediaPipe, we track push-ups, squats, and other movements in real time, validating form and counting clean reps only.

Health data integrations: Connected with Strava and WHOOP, so running, cycling, and recovery data can plug into challenges like 10k runs or endurance contests.

AI workouts: Gemini models personalize training plans and contests for each user, adapting intensity by age, gender, fitness level, and past performance.

Stack: React frontend + Flask backend tie everything together, managing live sessions, rep proofs, and contract interactions.

Live contests: WebRTC powers real-time video streaming so spectators can watch players compete while betting or cheering.

Anti-cheat: You can’t fake effort—our AI captures and processes real-time screenshots to validate liveness, form, and reps.

Future scope

We envision a DAO + data lighthouse, where anonymized fitness data becomes a community-owned asset—contributing to research and collective health initiatives while rewarding users for sharing.
