On November 10th, at the 2019 “Zhongzi Gravity” conference, Du Yu, deputy general manager of Wanxiang Blockchain, said that blockchain technology based on mathematical algorithms can build trust at a lower cost, based on algorithm rules and The technical code builds trust. From this perspective, the essence of the blockchain is the "trust machine." The blockchain has more applications in terms of security, efficiency, and process simplification. In terms of security, one is the security of system equipment, and the other is data security. In terms of efficiency, it is mainly to break down information islands and realize large-scale collaboration through data sharing. For process simplification, mainly computer programs run through processes. Instead of manual mode, automatic operation is realized for 24 hours.
