On November 22nd, Professor Guo Bing, deputy dean of the School of Computer Science (Software College) of Sichuan University and deputy director of the Sichuan IOO Engineering Technology Research Center, pointed out in the live speech of Chengdu IoT Technology Integration Application Exchange Salon, the so-called go Centralization is not an end, but a means. Decentralized blockchain actually makes the system complicated, but there is no way to achieve multi-party trust. Only everyone can do it together. Building a new business is the purpose of the blockchain. The blockchain technology itself has less innovation. It is an integrated innovation technology and a new application model. Its main value lies in the creation of subversive application models and new formats.
