According to the Securities Daily News, Wu Tong, deputy director of the CECBC Blockchain Committee of the Ministry of Commerce and dean of the Digital Economy Business School, said in an interview that the blockchain advantage lies in its role as a distributed accounting system that is difficult to tamper with. The data on the chain has a time stamp and the cost of tampering is high, which is consistent with the record requirements of the data in the commodity traceability anti-counterfeiting service. However, the blockchain still has challenges in the context of commodity safety traceability. He pointed out that “on the one hand, the identification at the source still requires centralization agency certification, and once the false information is authenticated and the chain is transferred, the harm is greater; Most of the traceability sources are that the QR code is not a commodity, and the goods in the package may be transferred. The blockchain still cannot avoid this problem."
