The Industrial Internet of Things (IIoT) aims to greatly improve the existing production procedures, enhancing customer experiences, reducing costs and increasing efficiency. IIoT will make a significant impact on existing business models in several areas. However, IIoT has several issues related to the security of the information and the excessive...

The problem I intend to address in my PhD research is related to the application of DLTs in resource-constrained industrial environments. Could it be feasible and effective to design a holistic multi-DLT architecture in order to tackle most of the challenges that are encountered when applying DLTs in IIoT? Here I present a multi-DLT architecture fo...

The Internet of Things (IoT) has become an essential part of our society. IoT devices are used in our houses, hospitals, cars, industry, etc., making our lives easier. Nonetheless, there are a number of serious concerns about security, privacy and performance issues in IoT. It has been proven that the aforementioned issues are strictly related to t...

The use of Distributed Ledger Technologies (DLTs) in the field of Industry 4.0 has been constantly increasing over the last years. In a complete Industry 4.0 ecosystem there are multiple smart factory clusters that belong to one or more companies and openly interact with their business partners, clients and suppliers. In such a complex ecosystem, m...

Industry 4.0 integrates IoT and robotics to create smart factories that work together seamlessly. However, this integration requires secure and efficient data management systems. Blockchain is a distributed ledger technology that stores data in a secure and transparent manner via cryptography mechanisms. Since the release of Bitcoin, it has gained...

Industry 4.0, also recognized as the fourth industrial revolution, symbolizes an innovative phase of manufacturing. It is driven by emerging technologies like Artificial Intelligence (AI), the Internet of Things (IoT), Big Data, advanced robotics, augmented reality, cloud computing, and cybersecurity. The prime focus is to digitally transform and i...
