Core Viewpoint - The incident involving the unilateral recall of discount coupons by Meituan highlights a significant trust crisis between the platform and consumers, revealing issues of transparency and consumer rights in the digital age [1][2]. Group 1: Incident Overview - Users reported that their discount coupons, obtained through a promotional activity, were suddenly revoked without prior notice, leading to widespread complaints [2]. - The customer service response indicated that the probability of coupon inflation was random, and the rules regarding coupon recall were not clearly communicated beforehand [2][3]. - Complaints surged by 60% on a single day, with the total amount claimed reaching at least 1260 yuan [2]. Group 2: Technology Solutions - The key to resolving such trust crises lies in digital twin technology, which can enhance transparency and accountability in platform operations [3]. - The FTE digital twin engine developed by Fantuo Shuchuang integrates multiple data sources to track the entire lifecycle of discount coupons, ensuring clarity in their generation, issuance, and usage [3][4]. - The technology allows for the visualization of abstract rules, enabling users to monitor their account status and identify any irregularities in real-time [4]. Group 3: Implementation of Transparency - Fantuo Shuchuang's solution includes a three-layer protective system for consumer rights, which consists of full-process mapping, smart contracts, and a regulatory sandbox [6][9][10]. - The full-process mapping layer creates a three-dimensional model of user accounts, displaying real-time updates on coupon attributes and modifications [7]. - Smart contracts can enforce platform rules automatically, ensuring that any changes to terms are communicated in advance [9]. Group 4: Broader Applications - The digital twin technology has been successfully applied in various sectors, including industrial manufacturing and urban management, demonstrating its capability to enhance operational efficiency and risk management [11][12][13]. - In the financial sector, the technology has significantly improved response times to security incidents and predictive maintenance, showcasing its versatility [10][11]. Group 5: Future Vision - The vision for the future involves creating a transparent ecosystem where consumers can confidently engage with digital assets, knowing their rights are protected and transactions are traceable [14][15]. - The implementation of this technology aims to establish a trust bridge between the physical and digital worlds, ensuring that every coupon and rule adjustment is verifiable and compliant [17].
