Towards blockchain-IoT based shared mobility: Car-sharing and leasing as a case study

Abstract

The shared mobility concept is seen as disruptive and transformative for the automotive industry. Shared mobility is changing the way we choose our travel mode, from just owning a car to e-hailing, car-sharing, and other relevant mobility solutions. There is a growing interest of car manufacturers (original equipment manufacturers or OEMs) in car-sharing as an expansion strategy. Similarly, blockchain technology is seen as another disruptive technology, which can potentially change how the data is stored and accessible via its immutable, transparent, and trustworthy features. Motivated by these two current trends, this paper aims to explore how blockchain and IoT technologies together can drive shared mobility forward. We have presented a high-level architecture for a blockchain-IoT-based platform for promoting shared mobility combining car-sharing and car-leasing. We also demonstrated a prototype implemented from the OEM’s point of view by developing a blockchain-IoT-based platform streamlining car-sharing and leasing processes by taking into consideration of primary stakeholders (such as OEMs, a peer-to-peer car-sharing provider, leasing company and insurance provider as well as public authorities). This work also demonstrates that the design of such an integrated platform depends on the right balance between the key design principles (such as security and privacy, authenticity, traceability and reliability, scalability, and interoperability) in the context of car-sharing platforms.
