On December 1, the construction of Hainan International Offshore Innovation and Pioneering Demonstration Zone and Blockchain • Digital Asset Trading Technology Innovation High-end Forum was held in Sanya. At the meeting, Xu Xing, founder of Eurotech Group, gave a speech on "The present and future of blockchain technology". Xu Mingxing mentioned that the application of blockchain is divided into instrumental and subversive. Tool-type applications such as traceability and certificate storage will slowly land one by one in government supervision and daily life. However, we can now see that there are many international remittances, Facebook's product Libra, etc. These are the embodiment of the development of disruptive applications.
