Massive Data Storage Solution for IoT Devices Using Blockchain Technologies.

The Internet of Things (IoT) concept involves connecting devices to the internet and forming a network of objects that can collect information from the environment without human intervention. Although the IoT concept offers some advantages, it also has some issues that are associated with cyber security risks, such as the lack of detection of malicious wireless sensor network (WSN) nodes, lack of fault tolerance, weak authorization, and authentication of nodes, and the insecure management of received data from IoT devices. Considering the cybersecurity issues of IoT devices, there is an urgent need of finding new solutions that can increase the security level of WSNs. One issue that needs attention is the secure management and data storage for IoT devices. Most of the current solutions are based on systems that operate in a centralized manner, ecosystems that are easy to tamper with and provide no records regarding the traceability of the data collected from the sensors. In this paper, we propose an architecture based on blockchain technology for securing and managing data collected from IoT devices. By implementing blockchain technology, we provide a distributed data storage architecture, thus eliminating the need for a centralized network topology using blockchain advantages such as immutability, decentralization, distributivity, enhanced security, transparency, instant traceability, and increased efficiency through automation. From the obtained results, the proposed architecture ensures a high level of performance and can be used as a scalable, massive data storage solution for IoT devices using blockchain technologies. New WSN communication protocols can be easily enrolled in our data storage blockchain architecture without the need for retrofitting, as our system does not depend on any specific communication protocol and can be applied to any IoT application.

Blockchain and third-party logistics for global supply chain operations: Stakeholders’ perspectives and decision roadmap

In global supply chains, third-party logistics (3PL) services have proven to be critically important in helping many supply chain agents with distribution tasks so that they can focus on their core competencies of product development and manufacturing. However, there are many inadequacies in current global supply chains that affect the functions of 3PL. These shortcomings have necessitated digital transformation in many businesses. This digitalization enhances information sharing and supply chain visibility, which improves supply chain performance; however, it may create challenges regarding cybersecurity and data quality. Blockchain technology (BCT), with features such as being highly secure and distributed, can help. In this paper, we examine the literature and identify challenges associated with 3PL and how BCT can be used for 3PL. Then, we conduct interviews with four innovation/project managers of well-established logistics companies to uncover the status of BCT adoption in 3PL and the challenges that are hampering the adoption of this technology. Finally, we propose a framework together with a decision roadmap for BCT implementation.

MedBust: Blockchain in Pharmaceutical Supply Chain

Counterfeit drugs are a major and growing concern globally, particularly during pandemics. One of the reasons for this is the inefficiency of the supply chain system in the pharmaceutical industry, which can make it difficult to trace the ownership of drugs from manufacturer to wholesaler, distributor, and pharmacist before it reaches the customer. In this study, we have evaluated different proposed blockchain-based supply chain management systems. The system that uses Hyperledger Fabric ensures data sharing, storage, transparency, and traceability in every stage of the supply chain. Meanwhile, the Ethereum architecture makes use of smart contracts to manage the communication between sender and receiver. The primary aim of the research is to improve the safety of pharmaceutical products and streamline supply chain operations with the most effective architecture. In addition to the benefits of transparency and traceability that blockchain technology can provide, it can also help to improve the overall efficiency and security of the supply chain. For example, by using smart contracts, automated processes can be put in place for the transfer of ownership and payment for drugs, reducing the need for manual intervention and reducing the risk of errors or fraud. Additionally, by creating a tamper-proof record of all transactions, blockchain technology can provide an auditable trail of the movement of drugs through the supply chain, which can be helpful for regulatory compliance and quality assurance. Furthermore, blockchain technology can also support the implementation of new business models in the pharmaceutical industry such as digitalized provenance records and tokenization of drugs to provide more transparency, security, and trust for the customer. It's worth noting that implementing blockchain technology in the pharmaceutical supply chain will require collaboration and cooperation between stakeholders in the industry, including manufacturers, wholesalers, distributors, and regulators. With the right approach and collaboration, blockchain technology has the potential to revolutionize the way that the pharmaceutical industry operates, making the supply chain more efficient, secure, and reliable, while also helping to reduce the risk of counterfeit drugs and protect public health.
