On November 22nd, the Chengdu Financial Technology Forum was held in Beijing today. Dai Qionghai, an academician of the Chinese Academy of Engineering and a professor of automation at Tsinghua University, attended and delivered a keynote speech. He said that the blockchain technology is very hot and very fragile. Based on peer-to-peer transmission, including sharing mechanism and encryption algorithm, it can be shared by everyone. It is worth exploring. It is very important to solve the problem of data security and trust. Blockchain technology has begun to be applied in the banking and finance field, but this application is not an overall application. Our current collection of chips, one is the improvement of the algorithmic power, the energy consumption is very high, and now there is photoelectric computing, the optical calculation does not require energy, and the computing power is increased by an order of magnitude. This technology is under study, and it is subversive to study. Technology can immediately change the current computing power.
