Consequences and Sustainable Solutions Using Systems Thinking and System Dynamics Analysis
Published on 2025-04-14 by Mohamd Laimon, Rula Almadadha, Steven Goh @MDPI
Abstract: Cryptocurrencies have gained global recognition, yet their rapid expansion is accompanied by significant environmental concerns due to their energy-intensive operations. This study employs novel system thinking and system dynamics approaches to examine the impact of cryptocurrencies on energy use, water consumption, and carbon emissions. The findings underscore the significant negative environmental impact resulting from cryptocurrency mining. According to our results, in 2023, the water consump[...]
Our summary: Consequences of cryptocurrency mining on energy use, water consumption, and carbon emissions are significant. Recommendations include adopting renewable energy for mining or utilizing energy-efficient technologies like the Pi network based on the Stellar Consensus Protocol. The environmental impact of cryptocurrencies is projected to increase sixfold by 2030 if no intervention is taken.

Zero-Trust Mechanisms for Securing Distributed Edge and Fog Computing in 6G Networks
Published on 2025-04-09 by Abdulrahman K. Alnaim, Ahmed M. Alwakeel @MDPI
Abstract: The rapid advancement in 6G networks, driven by the proliferation of distributed edge and fog computing, has introduced unprecedented challenges in securing these decentralized architectures. Traditional security paradigms are inadequate for protecting the dynamic and heterogeneous environments of 6G-enabled systems. In this context, we propose ZTF-6G (Zero-Trust Framework for 6G Networks), a novel model that integrates Zero-Trust principles to secure distributed edge and fog computing environme[...]
Our summary: Zero-Trust Framework for 6G Networks integrates Zero-Trust principles to secure distributed edge and fog computing environments, ensuring robust security through adaptive authentication, continuous verification, and fine-grained access control. The framework utilizes multi-layering, AI-driven anomaly detection, and blockchain-based identity management to reduce latency, improve throughput, resource utilization, trust score accuracy, energy efficiency, threat detection accuracy, and insider threat mitigation in 6G networks.

Challenges and Solution Directions for the Integration of Smart Information Systems in the Agri-Food Sector
Published on 2025-04-08 by Emmanuel Ahoa, Ayalew Kassahun, Cor Verdouw, Bedir Tekinerdogan @MDPI
Abstract: Traditional farming has evolved from standalone computing systems to smart farming, driven by advancements in digitalization. This has led to the proliferation of diverse information systems (IS), such as IoT and sensor systems, decision support systems, and farm management information systems (FMISs). These systems often operate in isolation, limiting their overall impact. The integration of IS into connected smart systems is widely addressed as a key driver to tackle these issues. However, it [...]
Our summary: Evolution of traditional farming to smart farming driven by digitalization, integration of diverse IS into connected smart systems is complex, review of 74 scientific papers on IS integration to address challenges and provide solutions.
