摘要

The transition to Industry 4.0 emphasizes secure, decentralized, and efficient operations. This study explores how blockchain, particularly smart contracts, enhances manufacturing by overcoming inefficiencies in traditional middleware systems. Integrating technologies like Augmented Reality (AR), Virtual Reality (VR), and Artificial Intelligence (AI) improves productivity, decision-making, and workflow efficiency. Digital twins, virtual replicas of physical entities, are also highlighted for their role in monitoring and diagnostics. Blockchain ensures data privacy and confidentiality in these systems. The study offers practical insights, backed by case studies, on the synergy of these technologies, emphasizing their economic and social impact on safety, development, and competitiveness.
