Due to the recent development of Industry 4.0, it is increasingly utilized in the manufacturing industry and has been extended to the management of logistics and supply chains, forming Logistics and Supply Chain 4.0. Similar to Industry 4.0, a wide range of emerging technologies, such as Internet of Things (IoT), extended reality (XR), and robotics, are exploited to transform conventional smart logistics and supply chain practices, generating numerous competitive advantages in terms of time, quality, and cost. Among the logistics and supply chain 4.0 technologies, sensors, such as temperature sensors and location sensors, play a significant role in facilitating effective data collection and acquisition. Corresponding sensor networks have also been built to handle and analyse the collected data to develop diversified smart logistics and supply chain applications.

However, modern sensor networks applied in logistics and supply chains are established under cloud-based infrastructures in a centralised manner, potentially leading to several pitfalls in cybersecurity and data integrity. An effective privacy-preserving strategy for managing supply chain data against malicious activities is needed across supply chain entities. With secure data management, identity management throughout the entire supply chain can be established in a trustworthy manner. Recent advances in blockchain technology with intelligent methods, such as machine learning algorithms, should be considered to construct tamper-proof, secure, and authentic sensor networks. Beyond cryptocurrencies and other financial services, further blockchain development, including smart contracts and consortium/federated blockchain, is promising to enhance the capabilities of cloud-based sensor networks under the IoT paradigm. Nonetheless, blockchain development for the IoT is still in an embryonic stage in both academia and industrial practice.

This Special Issue aims to incorporate advanced blockchain technology in modern sensor networks for logistics and supply chain 4.0 applications. Our objectives are to design and develop theoretically and practically sound blockchain-based sensor-driven logistics and supply chain systems in a broad spectrum of operational domains, including supply logistics, intra-facility and production logistics, reverse logistics, cold chain logistics, and e-commerce logistics. The purpose of this Special Issue is to encourage scholars and practitioners to publish and discuss novel and high-quality papers, such as new theories, experiments, system modelling, empirical investigations, and applications advocating the blockchain in sensor networks for logistics and supply chain 4.0, as well as for digital identity. We highly welcome both original research and systematic review articles.
