The People's Daily Overseas Edition today published "China's push for blockchain technology independent innovation." The article said that the blockchain technology has broad prospects for development and has a wide range of application scenarios, but it still faces many challenges. First, the issue of integration remains to be explored. The key word for blockchain is the "platform." To play the role of the blockchain, it is necessary to give full play to its platform functions. How to combine blockchain technology with other emerging technologies such as the Internet of Things, big data, and artificial intelligence to maximize its effectiveness is still a problem to be explored. Second, the core technology is the key. China is more focused on the development of blockchain. Compared with Western countries, there is still a certain gap in core technology. The lack of key technologies will directly lead to the new "card neck" link.
