In July of this year, the US Senate Committee on Commerce, Science and Transportation passed the Blockchain Promotion Act; the German government released the blockchain strategy in September this year, hoping to tap the potential of blockchain technology to promote economic and social digital transformation; Think of the blockchain as part of financial technology and attach great importance to it… In the face of the big trend, China cannot fall behind. General Secretary Xi Jinping emphasized that the integrated application of blockchain technology plays an important role in new technological innovations and industrial changes. It is necessary to pay attention to the status quo and trend of blockchain technology development, improve the application and management of blockchain technology capabilities, and make blockchain technology play a greater role in building network power, developing digital economy, and assisting economic and social development. Technology is a double-edged sword, and it is crucial to get rid of the disadvantages. The technology and industrial application of the blockchain is still in its infancy, and there is still a long-term landing. For example, the performance of the blockchain needs to be improved, and the gap of professional talents is also large, such as efficiency and security issues, data under the chain. Collaborative issues, regulatory issues, etc., also need to be highly valued by us. Therefore, only by strengthening the guidance and regulation of blockchain technology, strengthening the research and analysis of blockchain security risks, and promoting the safe and orderly development of blockchains, blockchains can truly serve the country and benefit the people.
