A Scheme to Optimize Roadside Parking Management by Using Blockchain Technology

In recent years, urban parking lots have gradually realized intelligent control through road gates, but roadside parking is still dominated by traditional manual charging management, with disadvantages such as low management efficiency and opaque transactions. In this paper, a roadside parking management system based on blockchain technology is proposed for this purpose. We propose a system architecture for on-chain and off-chain data collaboration in view of the fact that current blockchain throughput performance cannot support roadside parking scenario. The parking data collected through the edge server is stored in the off-chain data center, and its data digest is stored in the Hyperledger Fabric consortium chain established by multiple organizations. In this way, the system ensures the safety and reliability of data by comparing the consistency of on-chain and off-chain data at regular intervals or when needed. In addition, a block-truncated data structure optimization approach is proposed for the short review time of roadside parking transactions, which can significantly reduce the storage overhead. Finally, we briefly describes the system implementation methods and system test results.
