Special Issue Information

Dear Colleagues,

This Special Issue aims to explore the latest advancements in decentralized architectures and blockchain technology for building resilient and trustworthy systems, covering a broad spectrum from theoretical foundations to practical applications. As digital transformation deepens, traditional centralized systems face numerous challenges, including single points of failure, security threats, and scalability issues. Decentralized architectures and blockchain technology offer innovative solutions to these problems, with the potential to revolutionize how we design and implement reliable, secure, and efficient systems. The Special Issue will bring together pioneering research from academia and industry, concentrating on key areas such as theoretical foundations of decentralized systems, blockchain applications in physical infrastructure, integration with Internet of Things (IoT) devices, novel economic and social models and incentive mechanisms, security and privacy enhancements, scalability solutions, and real-world applications in various domains including but not limited to telecommunications, energy grids, smart cities, IoT, societies, and supply chains.

The Internet of Things has transformed industries, cities, and homes through a vast network of interconnected devices. As the IoT expands, the number of devices is projected to reach tens of billions, generating massive amounts of data. This growth presents significant data storage, management, and security challenges, especially in large-scale deployments such as smart cities and industrial operations. Traditional centralized solutions struggle to handle the high data volume and heterogeneity of IoT data, while ensuring real-time processing and interoperability. This paper presents the design, development, and evaluation of a blockchain framework tailored for the secure storage and management of data generated by IoT devices. Our framework introduces efficient methods for managing, transmitting, and securing data packets within a blockchain-enabled IoT network. The proposed framework uses a gateway node to aggregate multiple data packets into single transactions, increasing throughput, optimizing network bandwidth, reducing latency, simplifying data retrieval, and improving scalability. The results obtained from rigorous analysis and testing of the evaluated scenarios show that the proposed blockchain framework achieves a high level of performance, scalability, and efficiency while ensuring robust security being able to integrate a large number of IoT devices in a flexible manner.
