Smart Cash-On-Delivery: Enhancing e-commerce transparency with smart contracts and parcel lockers

This paper presents a novel cash-on-delivery method for e-commerce, combining blockchain-based smart contracts and parcel lockers to enhance transparency, trust, and efficiency in last-mile delivery. The system reduces payment risks for suppliers while ensuring timely deliveries and tracking customers. By integrating the Internet of Things (IoT) and blockchain, this approach addresses key challenges like fraud and delivery inefficiencies, paving the way for more secure and sustainable e-commerce logistics. Furthermore, this study serves as a roadmap for other academics and blockchain professionals, encouraging further experimentation and research to refine and validate this approach through practical applications and real-world testing.
