Package Delivery System Based on Blockchain Infrastructure

摘要

Blockchain technology has been recently applied in many applications including cryptocurrencies like Bitcoin, Internet of Things, healthcare, and supply chain management. The essential properties are the capabilities in doing verification and maintaining data integrity which would be hardly guaranteed in other systems. As millions of packages are daily sent, information related to those packages must be protected since they are prone to attacks such as phishing. In addition, current package delivery systems are mostly implemented on a centralized platform which would be vulnerable to different kind of attacks. In this paper, we propose a package delivery system based on the blockchain technology which would help enhance the security with data integrity and the verification of both users and data. We evaluate the performance of our system using two operations: insertions and reads/writes under high workload. We found that our system performance for both insertions and reads/writes is highly sensitive to the number of chains rather than the number of transactions per chain. But, the time spent for reads/writes is much higher than the time spent for insertions.
