Next-generation web 3.0 for digitalized industrial applications in the 5G/6G era

In recent years, the rapid development of 5G/6G networks has connected billions of IoT devices, generating massive amounts of data. Efficiently collecting, processing, and analyzing this data is crucial for gaining valuable insights and improving decision-making. However, the underlying communication networks face significant challenges in securely and scalably managing these devices, impacting infrastructure construction, maintenance, and management. Moreover, recurring data privacy breaches and a lack of control have diminished the willingness of users and enterprises to share data for processing and analysis. Web 3.0, with its emphasis on enhanced security and decentralized data management, offers robust solutions to protect sensitive industrial information. Its technologies enable transparent and tamper-resistant data exchanges, optimizing supply chain and asset management. Smart contracts boost operational efficiency, while self-sovereign identity systems ensure privacy compliance. Being compatible with 5G/6G networks, Web 3.0 seamlessly integrates with advanced communication infrastructures, promoting efficient data processing, communication, and resource management. The applications of Web 3.0 span across the Internet of Things (IoT), federated learning, and digital twins, all aiming to enhance data processing efficiency, security, privacy protection, and resource management optimization. This transformative technology is driving progress and innovation across various sectors, including industry, transportation, and data management, paving the way for a more connected and intelligent future.
