Wu Zhen, head of the Key Laboratory of Internet Financial Security Technology of the National Internet Emergency Center, said in an interview with CCTV's focus interview program today: "At present, we have monitored the blockchain company with the word blockchain or it operates. There are more than 32,000 blockchains in the range. This number is still relatively large. However, after actual monitoring, we found that there are actually not many companies that have blockchain technology or chain ownership. That is about 10% of this amount, or even less than 10%."
