== Abstract ==

​

 cities become increasingly dense, they must turn to novel technologies and frameworks to address the mobility challenges that will arise. 50% of trips in the U.S. are less than 3 miles, and could be replaced by a more sustainable and space-efficient mode of transportation, such as bicycling, if effective policies and incentives were implemented.   This abstract presents a financial incentives system to increase the prevalence of urban cycling. The blockchain-based system allows cyclists to receive financial compensation from organizations, such as city governments or local businesses, that would like to sponsor cyclists. Using bicycle-powered sensors, cyclists collect and redeem their activity data through smart contracts stored and executed on an Ethereum blockchain. The use of blockchain technology makes transactions secure, trustworthy, and timely.   This project envisions expanding this data platform to include additional bicycle-based sensors that cyclists use to collect and sell data, monetizing their commuting habits, and building a scalable and stable solution for encouraging sustainable transportation in cities.
