Babbitt reported on the spot that at the T-EDGE New Finance Summit 2019 and CHAINSIGHTS FinTech and Blockchain China Summit on December 8, Jean Tirole, winner of the 2014 Nobel Economics Prize, said that blockchain will bring more Good returns, lower costs, better services, and more access to financing. But for some countries and certain businesses, it brings disruptive effects and negative effects. Many people think that emerging technologies will be decisive. In some ways, it is true, but it is wrong to think so. Jean Tirole believes that blockchain technology cannot replace the status of banks. For example, banks assume the function of deposits and savings, and this needs to meet long-term and secure requirements. Blockchain has no way to replace these long-term banking services.
