Web3.0是当前值得关注的前沿议题，它包含了人机物网深度融合、虚实融合与交互、多样化业务服务、智能化运维管理和可量化安全能力等多个新兴领域。Web3.0在对技术、经济、社会、文明产生变革的同时，也面临着技术路径未明、内生安全风险、组织架构不清以及现有网络技术架构难以承载等挑战。与此同时，现有的网络技术范式已经难以支撑Web3.0的发展，也面临着理论与发展困境。基于网络技术第四范式及多模态网络环境理论，提出了建设中国下一代互联网的相关建议、把“统筹安全和发展的关系”和实现网络安全可量化设计、可验证度量作为关键问题和核心目标之一，构建应用驱动型的技术发展路径、建立网络技术领域自主知识体系等。
Web 3.0 is a frontier issue that deserves attention and involves a number of emerging areas such as the deep integration of human-machine and object networks, virtual-real integration and interaction, diverse business services, intelligent operation and maintenance management, and quantifiable security capabilities. It is difficult for the existing technical architecture to cope with the challenges. However, it is clear that the existing web paradigm is no longer able to support the development of Web 3.0 nor to meet the theoretical dilemma. Based on the fourth paradigm of network technology institutional development and the theory of multimodal network environment, this paper puts forward relevant proposals for building China's next-generation Internet, taking "co-ordinating the relationship between security and development" and achieving quantifiable design and verifiable metrics for network security as one of the key issues and core objectives. On this basis we propose to build an application-driven technology development path and establish an autonomous knowledge system in the field of network technology.
