With the development of social economy and technological innovation, the rise of blockchain, a new technology, has had a huge impact on our country and even the world. As a general-purpose technology, blockchain technology is accelerating its penetration from the digital currency field to other fields, and is integrating with innovations in various industries. At present, blockchain has attracted great attention and widespread attention from government departments, financial institutions, technology companies and capital markets in major countries around the world.

The penetration of the blockchain industry is accelerating, and China is in a leading position in the world

Since Satoshi Nakamoto proposed the concept of blockchain in 2008, blockchain has gradually transitioned from the technical preparation period to the application exploration period. At present, blockchain is accelerating its widespread penetration into all walks of life, and is continuously integrating and innovating in other fields such as finance, notarization, logistics, medical care, government affairs, etc., forming a good momentum of "blockchain +". According to Coinmarketcap statistics, as of the end of May 2019, there were 2,212 digital currencies in the world, with a total market value of US$265 billion. Among them, Bitcoin has the highest market value, reaching 90% in early 2017. Subsequently, due to the explosive growth of other digital currencies and the decline in Bitcoin prices, Bitcoin's market value has declined, but it has basically remained at 50% so far.

In recent years, the rapid rise of financial technology has provided innovative vitality for the sustainable development of the financial industry. Blockchain finance is currently the most anticipated development direction in the financial field. It has implemented many applications in cross-border payments, supply chain finance, securities transactions, bills, etc., showing great optimization power for the financial industry. Financial industry giants such as Goldman Sachs, JPMorgan Chase, and UBS Group have established their own blockchain laboratories, published blockchain research reports or applied for blockchain patents, and participated in blockchain start-up companies.

The "China Blockchain Development Report (2019)" released in Beijing on November 16 shows that in recent years, with the continuous innovation of various blockchain institutions in China in the technical field, the number of blockchain patents in China has grown rapidly, and has surpassing the United States to rank first in the world. The "Blockchain Patent Situation White Paper (Version 1.0)" released by the official website of China Academy of Information and Communications Technology shows that currently global blockchain patents are mainly concentrated in China, the United States, Canada, South Korea and the United Kingdom. From the beginning of 2013 to December 20, 2018, China applied for 4,435 blockchain patents, accounting for 48% of the total global blockchain patent applications; the United States applied for 1,833 blockchain patents, accounting for 21% of the global total. %.

According to statistics from the State Intellectual Property Office, as of March 31, 2019, the number of blockchain patents disclosed in China was 4,351, and the number of patents disclosed in the first quarter of 2019 was 2,041, a year-on-year increase of 5.4 times (the same period in 2018 (317), the number of China’s blockchain patents is likely to reach a new high in 2019. "The rapid growth in the number of blockchain patents in China not only represents China's emphasis on and promotion of blockchain technology, but also indicates that China will have more international say in the blockchain field." "China Blockchain Development Report" (2019)" stated.

Judging from the number of industry-related companies, China's blockchain-related registered companies ranked first, exceeding the global total. As of June 2019, there were 27,784 domestic blockchain-related registered companies. There are a total of 3,071 blockchain-related registered companies in the world. Among them, the United States has the largest number of blockchain-related companies, with a total of 1,430; the United Kingdom has the second largest number of blockchain companies, with a total of 465; Singapore, Australia, the Netherlands, and Canada have similar numbers. However, there is a decreasing trend, with 187, 137, 100 and 98 companies respectively.

There is a lack of international blockchain system standards, and regulatory legislation in different countries has different characteristics.

Although blockchain companies are springing up at home and abroad, there has never been a unified blockchain system standard that is internationally recognized. Many blockchain companies are also groping forward independently, which inevitably leads to deviations from the original intention of blockchain. Fishing in troubled waters, disrupting the market, and making huge profits.

Whether blockchain technology can truly bring positive effects to society depends on who uses the technology and how it is used, and the supervision of blockchain is also full of challenges. This challenge is caused by two aspects: First, cross-border. Taking the blockchain application in the financial industry as an example, financial technology, Internet finance and blockchain finance involve complex cross-borders. Regulators fail to fully understand the blockchain. In the case of poor application and regulatory means in the financial field and backward regulatory technology, it is easy to have a certain regulatory vacuum; the second is decentralization. All transactions under blockchain technology are anonymous and cannot be banned. Although transaction data are all It is open but cannot be effectively supervised. The solution to this problem depends on the continuous upgrading of supervision methods.

Experts said that judging from the international experience of blockchain legislation, the development of blockchain in mainstream countries in the world has its own characteristics, but countries generally choose to legislate various applications based on blockchain, rather than directly targeting regions. Blockchain itself is subject to legislative restrictions. In the legislative practice of various countries, countries are more concerned about the application of blockchain in the financial field or the application of blockchain with some financial attributes.

For example, Japan has enacted special legislation on virtual currencies and introduced registration-based supervision to regulate potential money laundering and terrorist financing risks of virtual currency exchanges and protect the legitimate rights and interests of users. The UK is one of the first countries in the world to establish a "regulatory sandbox" system, which allows many financial innovations to be carried out experimentally in specific small-scale markets to observe specific effects. The application trials of blockchain are in " "Regulatory Sandbox" operates internally and gradually achieves compliance under the supervision and guidance of the FCA (Financial Conduct Authority) based on the effects of sandbox testing. The U.S. SEC (Securities and Exchange Commission) characterized the issuance of virtual currencies using blockchain as the underlying technology based on the U.S. Federal Securities Act, citing the Howey rule established by the Federal Supreme Court.
