2. What are the opportunities and challenges in the innovative development of blockchain that we must seize?

In this new era of the 20th century, there are many opportunities that we need to seize, not only for us personally but also for our country, seizing the opportunities is also a very important thing. The new century is a new opportunity and challenge for the whole world. New technology and economy have many impacts on all aspects of our lives. And the latest "digital economic development," has laid an important foundation for the development of today's era. So what is the development and innovation of blockchain?

The whole world is innovating and developing, and we need to see the right time to seize the opportunity. Opportunities are reserved for those who are prepared.

3. What are the application directions and prospects of China’s blockchain?

Since 2019, blockchain has been constantly mentioned. As a key technology for the next generation of Internet, governments and giant companies from various countries have stepped up their efforts in the research and application of blockchain, and the competition for the right to formulate industry standards has become increasingly fierce.
According to the "2019-2020 Global Blockchain Technology Layout and Business Investment Trend Research Report" released by iiMedia Consulting, with the further liberalization of policies in the future, China's blockchain industry will usher in a stage of rapid development and is expected to Enter the first echelon of the global blockchain industry in an all-round way.
1. Protection of policy dividends, accelerated formation of technical standard system
The importance of blockchain technology to the new round of industrial transformation has received increasing attention, and major countries around the world have accelerated the research and development of blockchain technology. , but because the industry has not yet formed a unified technical standard system, blockchain is still subject to many restrictions in application and promotion.
2. Ending the barbaric growth and the industry entering a new stage
After the capital winter in 2018, a large number of blockchain companies were eliminated and the overall popularity of the industry declined., capital returns to rationality, and the barbaric growth stage of the blockchain industry is coming to an end. In 2019, policy factors will bring blockchain back to the forefront of development, and capital and talents will once again flow into the blockchain industry track. As applications, supervision, and standardization continue to advance, truly competitive blockchain companies will gradually emerge, and the industry will usher in a new round of rapid growth.

4. What are the future development prospects of blockchain technology?

Blockchain is a technology. “In the simplest and most popular terms, blockchain technology is everyone’s Accounting, or distributed ledger."
In the Internet era, there is a database behind every system. This database can be regarded as a large ledger. In the past, the person maintaining the system was responsible for managing the database and recording the user's information. Behavior, that is, accounting, and the blockchain is "decentralized", which allows every member of the system to participate. Not only does everyone keep accounts, but through links, everyone can have a complete ledger.
"Blockchain is essentially a collective recording method. What is special is that it uses a unique set of technologies to achieve the authenticity and credibility of the recording results, which is difficult to destroy and cannot be tampered with." Zhang Xiaorong said, " First, everyone has the right to record and authenticate each other to distinguish authenticity. This is called a consensus mechanism; second, no one can tamper with records because there is a cryptographic signature; third, everyone has a copy, so even if there is a ledger If it is damaged, the whole will not be affected. This is called distributed storage. The information recorded in this way is presented in blocks according to the time chain, so it is called blockchain."
Each currency represented by Bitcoin This encrypted digital currency is originally an application of blockchain technology, which can be said to be version 1.0 of blockchain. But around 2014, the industry began to realize the important value of blockchain technology. Blockchain was gradually separated from digital currency and applied to various economic and social fields other than digital currency.
Broad application prospects
Blockchain technology is considered a disruptive innovation after steam engines, electricity, and the Internet. If steam engines and electricity have liberated productivity, and the Internet has changed the way information is transmitted, then blockchain, as a machine that builds trust, will likely change the way value is transmitted.
For example, in the financial field, the cost of reconciliation, clearing, and settlement between financial institutions, especially cross-border financial institutions, has always been very high, and there are complex manual processes. However, blockchain technology has data that cannot be tampered with and is traceable. Its application can help reduce the cost of reconciliation and dispute resolution between financial institutions, significantly improve the processing speed and efficiency of payment services, and make small-amount cross-border payments possible. In December 2017, China Merchants Bank completed the transfer of RMB positions from Hong Kong Wing Lung Bank to Wing Lung Bank Shenzhen Branch. This is the world’s first inter-bank cross-border RMB clearing business based on blockchain technology.
In addition, according to the "China Blockchain Technology and Application Development White Paper 2016" issued by the Ministry of Industry and Information Technology of China, the application of blockchain has extended to medical health, education, charity, social management, etc.Multiple areas. Taking the cultural industry as an example, intellectual property protection has always been a pain point in the industry due to low copying costs, high rights protection costs, and difficulty in providing evidence. With the blockchain, the records of the production, dissemination, and transactions of cultural products are authentic, transparent, credible, and verifiable, and the problem can be easily solved.
Cheung Hsiao-rong said that blockchain technology solves two major problems in the digital economy era: first, the flow direction is visible, and second, there is zero trust cost. In the past, the circulation of physical banknotes was invisible, but the flow of all digital assets has a "chain" that can be checked. Yang Yanchao, a researcher at the Intellectual Property Center of the Chinese Academy of Social Sciences, also believes that the biggest advantage of blockchain is that it truly completes the construction of credit in an anonymous society and brings new opportunities to many fields, thus making various innovative applications possible.
There is a long way to go for future development
In terms of technology promotion, there are not too many barriers to blockchain. This has been proven in the global practice of Bitcoin. The main resistance still comes from conceptual and implementation obstacles.
"On the one hand, society may be very concerned about the 'naked' state in the blockchain. The blockchain builds a 'Skynet' for the business society, and all the company's economic activities are recorded, so there is no There is no secret at all, and such business strategies may not be implemented under the blockchain."
"On the other hand, the current legal system lags behind the development of information technology. How can the emerging blockchain technology be placed under the law? It needs to be studied under supervision." Duan Yongchao said.
The core of blockchain is decentralization, which will have an impact on the central management model that has been formed in society for a long time. In addition to laws, how to establish a regulatory environment that can promote the application of blockchain technology so that the technology can benefit society and not be used for evil is also an urgent problem to be solved.

Therefore, from the perspective of employment direction, blockchain technology talents can choose to work in different types of units such as financial institutions, technology companies, innovative enterprises, government agencies, etc., and engage in blockchain technology Development, application research, technical support, project management and other related work. At the same time, you can also expand your career development path through entrepreneurship and other methods.

6. Blockchain engineering employment direction and prospects

The employment prospects are broad and currentlyAt this stage, blockchain technology is still in the stage of systematic development and technical application exploration, so relevant practitioners are mostly focused on theoretical research and exploration and development of implementation scenarios.

With the vigorous development of Blockchain 2.0 and the proposal of the concept of Blockchain 3.0, Blockchain technology has expanded from the financial field to all aspects of social life, and a large number of enterprise-level applications have begun to use Blockchain technology.

In addition, the market currently lacks comprehensive technical talents who understand computer technology, have relevant algorithm foundations, and can use Ethereum and Hyperledger Fabric applications. For developers, blockchain application development will be a new continent.

1. Block + chain

As the name suggests, blockchain is a database formed by blocks combined in a chain. We call it a blockchain database. Blockchain is a transaction database shared by all nodes in the system. These nodes participate in the blockchain network based on value exchange protocols.

2. Distributed structure

The blockchain builds a distributed structural system based on the open source and decentralized protocol determined by the system, allowing value The exchanged information is sent to the entire network through distributed propagation, and the information data content is determined through distributed accounting, stamped with timestamps to generate block data, and then sent to each node through distributed propagation to achieve distributed storage.

3. Asymmetric encryption algorithm

To put it simply, it allows us to use two passwords respectively in the process of "encryption" and "decryption". Passwords are asymmetric.

4. Script

A script can be understood as a programmable smart contract. With scripts in place, blockchain technology will give the system the opportunity to handle some unforeseen transaction patterns, ensuring that this technology will not become outdated in future applications and increasing the practicality of the technology.

7. What are the application prospects of blockchain?

The application prospects of blockchain are mainly in the financial field, Internet of Things and logistics, public services, digital copyright, and insurance. .

1. Blockchain has huge potential application prospects in financial fields such as international exchange, letters of credit, equity registration and stock exchanges. The application of blockchain technology in the financial industry can eliminate the need for third-party intermediaries and achieve direct point-to-point connection.

2. Blockchain can also be naturally combined in the Internet of Things and logistics fields. This field is considered to be a promising application direction of blockchain. Establishing credit resources in the blockchain can double improve the security of transactions and improve the convenience of IoT transactions. Save time and cost for smart logistics model applications.

3. Blockchain is closely related to people’s production and life in public management, energy, transportation and other fields. The decentralized, fully distributed DNS service provided by the blockchain serves through point-to-point data transmission between various nodes in the network.Domain name query and resolution can be realized.

4. Through blockchain technology, works can be authenticated, proving the existence of text, video, audio and other works, and ensuring the authenticity and uniqueness of ownership. After the rights of the work are confirmed on the blockchain, subsequent transactions will be recorded in real time, realizing full life cycle management of digital copyright, and can also be used as a technical guarantee in judicial evidence collection.

5. In terms of insurance claims, insurance institutions are responsible for fund collection, investment, and claims settlement, and often have high management and operating costs. Through the application of smart contracts, there is no need for the policy holder to apply or the insurance company to approve it. As long as the claim settlement conditions are triggered, the insurance policy can automatically settle claims.

(7) Extended reading on blockchain technology opportunities:

Core technology of blockchain

1. Consensus mechanism, Through the voting of special nodes, the verification and confirmation of the transaction can be completed in a very short time; for a transaction, if several nodes with unrelated interests can reach a consensus, it can be considered that the entire network can also reach a consensus on it. The goal of the blockchain consensus mechanism is to enable all honest nodes to maintain a consistent view of the blockchain.

2. Asymmetric encryption requires two keys for encryption and decryption. These two keys are the public key and the private key. The public key corresponds to the private key. When the public key is used in the encryption process of data, it can only be decrypted by using the corresponding private key. On the contrary, when the private key is used in encrypting the data, only the corresponding private key can be used to decrypt the data. Only the corresponding public key can be decrypted.
