Core Viewpoint - The current commodity trading market relies on traditional models, leading to high user acquisition costs and low effectiveness, which hinders the formation of a large-scale trading ecosystem. New technologies are needed to transition from "Internet of Everything" to "Internet of Trust" to establish a credible trading market for commodities [1][4]. Group 1: Current Challenges - The existing trading model suffers from issues such as incomplete trust in trading entities, data, and processes, along with frequent leaks of personal privacy and business secrets. This results in high intermediary costs and fragmented market information, which are global and foundational problems difficult to resolve under the current framework [2][3]. Group 2: Proposed Solutions - The rapid development of new information network technologies like cloud computing, big data, IoT, AI, and blockchain provides the necessary foundation to fundamentally address the issues of the current model and meet the evolving demands of users [4]. - A proposed overall architecture for a credible trading market includes: 1. Establishing a globally open infrastructure for credible commodity trading, allowing all market participants to register their real, compliant identities and publish genuine supply and demand information [4]. 2. Providing personalized trade terminal systems for participants to easily access the infrastructure and conduct trade activities securely [4]. 3. Offering regulatory facilities for government departments to enable proactive and intelligent oversight when necessary [4]. Group 3: Implementation Strategy - The only viable strategy for building credible trading infrastructure is government-led with market-oriented operations. This approach emphasizes the distinct roles of government and market, leveraging their respective advantages. The government should provide regulations, standards, policies, and financial support, while enterprises focus on construction and operation [5].
