In addition, "information The development of IoT has three stages: pre-outbreak, barriers" and challenges to creating "on-chain" physical assets outbreak, and full-scale outbreak. At present, the core are affecting the implementation of blockchain technology in technology of the global IoT continues to develop, with the Metaverse. the creation of unified standards, an improving industrial ecosystem, and a rapidly developing global IoT industry. Regulatory compliance However, it will take a few more years before the IoT There are also policy risks in the continuous development outbreak. of the blockchain. Bad actors can easily use the anonymity and anti-tamper characteristics of the blockchain to spread Three challenges need to be solved for IoT to achieve scale misleading information, threaten network security, and and accelerate its evolution: damage user privacy. First, high cost. IoT is costly because there are so many In addition, there have been frequent cases of illegal financial types of sensors, including camera, weather, and pollution activity under the banner of "blockchain", disrupting the sensors. This makes it difficult to create scale effect, and normal market order. Figure24: IoT development Full-Outbreak Outbreak Demand-side pull, ubiquitous, definable, and Pre-Outbreak The supply side and the demand side have basically creation of unified infrastructure Pulled by the supply side, some industries have initially achieved a balance, industry boundaries have begun to blur, achieved scale and local interconnection and the scope of horizontal data circulation has increased 5G Network Deployment Standardization of Private Network of IoT Penetrates All Terminals, Networks, IoT Emerged, Accelerates, Vertical Walks of Life Equipment, etc. Realizes Giants Entered IoT Application Business True IoT Breakthroughs 2016 2020 2030 2050 Source: Public information, Deloitte analysis 28
