China Payment Clearing Association, Beijing Blockchain Technology Application Association, and Social Science Literature Publishing House recently released three blue books on financial technology, regulatory technology and blockchain in Beijing. The blockchain blue book report pointed out that there are nearly 28,000 blockchain enterprises in the country, including Beishangguangshen and Shenzhen as the core gathering place. Guangdong Province blockchain registered enterprises account for over 50% of the national blockchain registered enterprises, totaling 16,353. Blockchain technology is also facing serious privacy leaks while improving efficiency, reducing costs, and improving data security. Zhu Yidong, president of the Beijing Blockchain Technology Application Association, said in an interview that 25,000 are issued by currency, and about 4,000 are used for application. The first thing we should pay attention to is to prevent risks. Do not think that some enterprises such as illegal fund-raising and such financial frauds are considered to be a blockchain application enterprise, high-tech enterprise to focus on support, or to introduce blockchain technology. Not so mature, or in the process of development, there is still a high room for improvement.
