Blockchain is a new integrated application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Broadly speaking, blockchain technology uses blockchain data structures to validate and store data, use distributed node consensus algorithms to generate and update data, and use cryptography to ensure data transmission and access security, using automated scripts. The code consists of a smart contract to program and manipulate data in a completely new distributed infrastructure and computing approach.
The blockchain contains four main characteristics: one is open and consensus; the other is to go to the center and increase integrity; the third is transparent transaction and the two sides are anonymous; the fourth is difficult to tamper and traceable. Therefore, the blockchain, with its unique advantages, will play an extremely important role in the application of innovative industries and the improvement of social governance.

The blockchain alliance has accelerated the development of China's blockchain. According to incomplete statistics, there have been more than 30 different types of blockchain alliances in China in the past two years, mainly in cities such as Beijing, Shanghai and Shenzhen. For example, the Golden Chain Alliance, which was established in May 2016, is a voluntary organization composed of financial institutions that actively promote the development of blockchain technology and enterprises that provide scientific and technological services to financial institutions.
Understanding of the development of blockchain
(1) Blockchain changes the way digital resources are stored and transmitted
The technical characteristics of the blockchain determine its ability to transcend the value transfer model dominated by traditional central institutions, helping people to exchange various values in a new, fast and intermediary-free way, thus changing the way social values are transferred and reshaping. Organizational form, promote the re-integration of resources, and change the operational logic of the industry.
In the financial sector, whether it is payment, lending, trading, crowdfunding or credit reporting, the blockchain can reduce the cost of various business in the financial industry with its decentralized and non-tamperable trust mechanism, and fundamentally improve efficiency; In the field of health care, the blockchain can provide high-intensity security for the sharing and storage of data in the healthcare industry, and ensure the transparency and reliability of data. In the field of logistics, the overall transportation process can be carried out through blockchain technology. Reduce, improve efficiency, the public can verify and monitor product and logistics processes, and so on.
(II) The development of blockchain is still in the early stage of research and exploration
Overall, the development of blockchain technology can be divided into four phases: the first phase, with digital currency as the starting point, research related applications and support software and hardware; the second phase, based on digital assets, research various assets in the district Secure digital registration on the blockchain; the third phase, the development and popularization of smart contracts, the evolution of ecosystems; and the fourth phase, the combination of digital assets and ecosystems to enable the application of blockchain mechanisms.
At present, most of the global blockchain technology development still stays in the first stage of digital currency as the main form, that is, at the level of concept development and architecture construction. The development direction of the underlying technology is still uncertain, the application scenarios still need to be implemented, and the industry standards are also very blurry. At the same time, blockchain technology still has many problems or defects in structured figures, consensus mechanisms, and supervision. According to Gartner analysis, the time required for the blockchain technology to reach maturity is about 5 to 10 years.
(3) Blockchain will likely lead to profound social management and integrity system reform
The wide application of blockchain technology will accelerate the arrival of “digital credit society” and lead to changes in government management and social credibility. The distributed ledger technology of the blockchain will help the government to levy taxes, issue benefits, issue passports, register land ownership, ensure the operation of the goods supply chain, and ensure the correctness of government records and services as a whole. Distributed ledgers also provide a new way to ensure ownership and origin of goods and intellectual property.
As a new type of underlying information technology, blockchain, with its open data transparency, high information security and strong traceability, may change the Internet governance model and promote the Internet as a new credit infrastructure to achieve effective value transfer. At the same time, blockchain technology may also improve existing business rules and build a new model of industrial collaboration.
(4) There are security risks in the blockchain
The security risks of the blockchain at the technical level are: trying to change the transaction information on a previous block; trying to control the generation of the new block. The key to solving these two problems lies in the enormous computing power represented by solving the math problems.
The security risk of blockchain is: all nodes synchronize data, and the efficiency is low; block generation requires a large amount of calculations of miners (people or organizations competing for billing rights in blockchain networks), which consumes energy; The transaction data is open and transparent, and there are privacy protection issues; the centering and autonomy features provide shelter for the black industry.
Suggestions on the development of China's blockchain
(1) Strengthening the security and supervision of blockchain at the level of security and governance
Self-controllable, safe and reliable is the most important issue that needs to be paid attention to in China's development blockchain. The currently immature blockchain technology is facing serious challenges such as platform security and application security. In June 2016, TheDao, the world's most popular project based on blockchain technology, was hacked, resulting in the hijacking of more than 3.6 million Ethereum worth $60 million. At the same time, a regulatory environment that promotes the application of blockchain technology should be established. If the traditional regulatory model is applied, it will be possible to curb the application innovation of the blockchain and make it unable to play its due role.
Therefore, we should strengthen the research on the security of blockchain in China, and improve the relevant laws and regulations from data security, technical security, and scene security according to the technical operation characteristics of the blockchain to prevent and reduce the potential risks of the blockchain. In addition, we must improve the means and methods of blockchain supervision, learn from foreign regulatory experience, and realize the safe application of blockchain in China.
(2) At the technical level, increase the research and development of the core technology of blockchain
China is still in the initial stage of blockchain R&D. It is necessary to strengthen the tracking research on the international development of blockchain, strengthen the research and development of key technologies in China's blockchain, increase R&D investment, and establish a public service platform for R&D of blockchain technology. . It is necessary to pay attention to the R&D and optimization of the bottom layer and basic technology of the blockchain, focus on creating the underlying platform of the independent and controllable blockchain, and strive to gain more discourse power in the global blockchain core technology R&D competition.
(3) At the application level, promote the pilot application of blockchain in public services and other fields.
Blockchain has broad application prospects in the fields of finance, public services, medical care, and logistics. Despite the current scalability, privacy and security of the blockchain, and the lack of mature open source projects, existing applications have fully demonstrated the value of blockchain. Therefore, it is recommended that China should promote the pilot application of the typical field of blockchain. For example, in the public service, finance and other industries, the appropriate departments will be the main nodes of the blockchain and participate in the operation of the blockchain network. Master and evaluate the impact of blockchain applications and possible risks to achieve effective regulation of blockchain security applications. (People's Venture Capital)
