A few days ago, in an interview with reporters, He Baohong, director of the Institute of Cloud Computing and Big Data at the China Institute of Information and Communications, said that the blockchain is not used to subvert the world, but a new technology. At present, the blockchain is developing rapidly. In the past year, it has mainly completed market education, and then it needs to develop into industry application scenarios. For example, the underlying technology should be optimized while exploring applications in specific scenarios, including applications other than non-digital currencies such as bills and taxes. There are also more and more giants entering this field. With the leading role of giants, blockchain is expected to form a formal and rapid development.
