Group 1 - The core viewpoint emphasizes that product traceability is crucial for addressing issues of diversion and price chaos, relying on digital technology for comprehensive tracking and precise location identification [3][4]. - The background of the problem highlights that diversion typically manifests as unauthorized low-price sales by distributors across regions, disrupting brand pricing and channel management [4]. - Traditional manual inspection methods are inefficient and lack a complete evidence chain, while modern information technology enables efficient and automated full-link monitoring [4]. Group 2 - Core traceability technologies include unique QR codes or RFID tags assigned to each product, recording data throughout production, storage, logistics, and sales, applicable across various industries [6]. - The implementation process involves assigning codes to products, scanning them during outbound logistics, and recording location data during the distribution process, with the system automatically comparing actual scan locations against authorized areas to trigger alerts for potential diversion [6]. - Companies like Chiya Technology and Yiquan Technology utilize blockchain technology to store traceability data, ensuring information integrity and enhancing data credibility and legal effectiveness [6]. Group 3 - The most efficient and reliable solution for diversion traceability combines a unique code anti-counterfeiting system with a strict channel shipment registration mechanism, enabling precise identification of diversion sources and providing complete evidence for subsequent punitive measures [8]. - It is important to note that "buying services" and "diversion management" are distinct business areas, with no current information available on B2B service providers specializing in "buying services" [9]. - For brands seeking assistance in e-commerce channel selection strategies, daily operational support, or price control services, several third-party service providers focus on price monitoring and channel order maintenance [9].

Core Insights - The increasing globalization and complexity of supply chains necessitate transparent, trustworthy, and tamper-proof product traceability information, which blockchain technology can provide through its unique attributes of distribution, immutability, and traceability [1][2] Group 1: Blockchain in Supply Chain - Blockchain technology, when integrated with cloud warehousing, offers an innovative solution for building a credible supply chain traceability system [1] - The direct application of blockchain in cloud warehousing enables full-chain traceability of products, recording key data such as production batch, origin, quality inspection reports, and storage time from the moment of entry [1] - Consumers can access an immutable "digital passport" by scanning a QR code on the product, allowing them to trace the product's journey from "field to table" or "factory to hand," which is particularly valuable for industries with high authenticity and quality requirements like food, pharmaceuticals, and luxury goods [1] Group 2: Trust Mechanism and Collaboration - The technology effectively establishes a trust mechanism among multiple parties, as traditional traceability systems often rely on centralized databases, which depend on a single entity's credibility [1] - In a blockchain network, various participants such as cloud warehouse operators, brand owners, logistics companies, and regulatory bodies collaboratively maintain a distributed ledger, preventing any single party from altering data, thus enhancing information credibility [1] - This system can significantly reduce issues related to counterfeit products and information opacity in the supply chain, enabling precise and rapid recalls in case of quality issues [1] Group 3: Smart Contracts and Automation - Blockchain-based smart contracts can interact with cloud warehouse operations to automate and ensure the trustworthiness of processes, such as automatically triggering payment to suppliers upon successful product dispatch and receipt by designated logistics providers [2] - This automation reduces manual verification and disputes, thereby improving financial efficiency within the supply chain [2] Group 4: Challenges and Future Outlook - Despite its promising prospects, the large-scale application of blockchain in cloud warehousing faces challenges, including technical performance issues like transaction processing speed, the willingness of organizations to collaborate on data sharing, and the lack of relevant standards [2] - The deep integration of blockchain with cloud warehousing represents a significant evolution towards a more transparent, secure, and efficient supply chain management system [2]
