Li Lihui, the leader of the Blockchain Research Working Group of the China Internet Finance Association and the former President of the Bank of China, said in an exclusive interview that after ten years of development, blockchain technology should be said to be still in an initial application stage. Commercial applications, but the overall scale is not large. In addition, many applications are experimental. Therefore, the blockchain technology is not yet very mature, and the bottleneck of the large-scale and reliable application of the blockchain has yet to be broken. We are still in the critical opportunity period of blockchain technology and industrial innovation.
