According to CoinDesk, an early-stage app called Moonwalk allows users to increase the stakes for their fitness goals by contributing cryptocurrencies to join a challenge. If participants fail to meet their daily step goal, they forfeit money to a prize pool shared by the other participants. The app is based on the premise that people are more likely to achieve their fitness goals when there is an external force holding them accountable, such as friends or financial rewards. In Moonwalk, both factors are present.

The app is currently in its testing phase, with a small group of users participating in a three-day challenge with a buy-in of $1,000 in USDC stablecoin. Each participant must walk 10,000 steps a day, and for each day they miss the goal, they surrender $333 to the prize pool. At the end of the challenge, those who meet the daily goal split the pool. Participants have full control of their original deposits and will get their money back as long as they walk 10,000 steps a day.

Moonwalk's ambitions extend beyond step-counting and into various areas of fitness, with plans to create more games incentivizing positive behavior change. For now, the app is limited to tracking steps, but it has already proven to be a fun and engaging way for users to stay motivated and achieve their fitness goals while potentially earning some extra money.
