Correct understanding and use of blockchain can promote the high-quality development of the real economy.

Blockchain can be applied in different fields of national governance, commerce, finance and industry. However, at present, the global blockchain industry is in the early stages of development, with a smaller scale, fewer replicable business models, and greater room for application. It is predicted that from 2019 to 2021, blockchain technology will gradually be pushed to the ground. The next three years will be the golden period for the development of blockchain technology. From a practical point of view, blockchain technology has expanded from digital assets to multiple fields such as bill management, product traceability, evidence forensics, copyright protection, data sharing, intelligent manufacturing, and serving people’s livelihood.
