On October 24th, the Political Bureau of the CPC Central Committee conducted the eighteenth collective study on the current status and trends of blockchain technology development. The General Secretary of the CPC Central Committee Xi Jinping emphasized during the study that the integrated application of blockchain technology played an important role in new technological innovation and industrial transformation. We must regard blockchain as an important breakthrough in independent innovation of core technologies, clarify the main attack direction, increase investment, focus on overcoming a number of key core technologies, and accelerate the development of blockchain technology and industrial innovation.

For a time, the blockchain technology became the "venture" of emerging technologies. So, what exactly is the blockchain that has attracted the highest leadership of the country? What does it have to do with our lives?

Blockchain originated from Bitcoin, but its development has greatly exceeded the scope of Bitcoin. From a technical perspective, blockchain technology can be understood as a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms.

Chen Chun, a professor at Zhejiang University, told a vivid story to help us understand: "In a village, Zhang San lent 100 yuan to Li Si. He wanted everyone to know the bill and broadcast it through the village's radio station. All When the villagers heard the broadcast and received the information, they would verify the authenticity of the information in their own way, and then wrote this information on their own books. In this way, all the villagers 'books were written,' Zhang San loaned to Li Si 100 yuan '. There will be no disputes about this loan afterwards, and there is no possibility of fake accounts. "This accounting system is distributed or multi-centralized, and the ledger data is assembled and arranged into blocks according to time sequence. , Blocks become a blockchain we call.

It can be seen that the data information recorded by the blockchain has the characteristics of openness and transparency, traceability, and resistance to tampering. It definitively solves the problem of authenticity of information, helps to share information and data, improves collaboration efficiency, and reduces communication costs.

More and more countries and enterprises have "watched" these advantages of the blockchain and are "chaining" it into practical applications. As a big Internet country, China started earlier in blockchain technology. According to the "Blockchain White Paper (2019)" issued by the Ministry of Industry and Information Technology, the number of China's blockchain companies is currently 499, second only to the United States in 553; among the top 20 global blockchain patent application agencies, Alibaba, China The number of applications such as Unicom ranked first and fifth in the world, respectively. At present, blockchain technology has gradually been applied to all areas of national life, solving problems for us.

Maybe we didn't realize that the electronic invoice issued by WeChat is likely to be supported by blockchain technology. Since Tencent issued the nation's first blockchain electronic invoice in August last year, as of October 30, its number has reached 10 million. The invoicing company that issued the 10 millionth blockchain electronic invoice stated that it experienced a lot of convenience after launching the blockchain electronic invoice: the adoption of blockchain electronic invoices helps to avoid fake invoices and improve the invoice supervision process, and Conducive to reducing costs; after checkout, consumers can apply for invoicing through WeChat self-service, and invoice information is synchronized to enterprises and tax authorities in real time, which is very convenient.

In December last year, Zhejiang Taizhou Central Hospital became the first pilot institution of "Zhejiang Blockchain Electronic Bill Platform". In June this year, the hospital's per-patient consultation time was shortened from 170 minutes to 75 minutes, and the insurance claim period was reduced from half a month to several minutes. And such bills have already been issued over 10 million in Taizhou alone. The relevant person in charge of the Zhejiang Provincial Department of Finance said that "the tamper-resistant blockchain technology also eliminates the possibility of fake invoices and repeated reimbursement."

In addition, with the help of AnChain Cloud Blockchain, Pyrotech Philanthropy has recorded the public welfare donations, capital flows and usage of all users on the blockchain. We can track and query the charitable fundraising information at any time. This practice This will help to make public welfare projects do their job better.

In addition to applications in medical, e-commerce, gaming, public welfare, and sharing economy, blockchain technology can also help to solve the problem of cross-regional government information service problems. For example, this year, with the help of blockchain technology, the head office of China Construction Bank and the Ministry of Housing and Urban-Rural Development of China completed the interconnection of 491 urban provident fund centers in the country in a short time, which facilitated the application of provident funds across regions.

The emerging blockchain technology has broad application prospects. But the application of any innovative technology should be based on legal compliance, and we need to face the "blockchain fever" rationally.

Ye Ye, chairman of People's Daily, said that if we look at blockchain technology from the perspective of development, we cannot underestimate its tomorrow; we also need to look at the blockchain label from a scientific perspective and cannot overestimate its today. The development of blockchain may face regulatory risks, but we must continue to look at the blockchain industry from a strategic perspective.

Huang Zhen, a professor at the Central University of Finance and Economics, also reminded that technology is a double-edged sword. Blockchain technology, like many cutting-edge technologies, can both create value and be used maliciously. At the same time, it is necessary to prevent the concept of blockchain from becoming a bubble in the heat of the capital market.

At the same time, regarding the issuance and promotion of digital currencies represented by bitcoin in China, on November 13, the People's Bank of China issued an announcement saying that the People's Bank of China did not issue legal digital currencies or authorize platform transactions to remind the public that it may involve Risk of fraud and MLM to prevent damage to interests.
