General Secretary Xi Jinping emphasized during the 18th collective study session of the Political Bureau of the CPC Central Committee, “Take blockchain as a core technology An important breakthrough for independent innovation” and “accelerating the development of blockchain technology and industrial innovation”.

The forward-looking judgment of the Party Central Committee has brought "blockchain" into the public eye and has become a common concern for financial capital, the real economy and social public opinion.

From network power to big data, from media convergence to blockchain, the Political Bureau of the CPC Central Committee has collectively studied and aimed at the forefront of technological change, demonstrating the direction, forward-looking judgment and future foresight of the Party Central Committee, leading It follows the pace of China's industrial reform and economic transformation. This collective study by the Political Bureau of the Central Committee specifically emphasized "blockchain", which opened up imagination space for the development and application of blockchain.

From a technological perspective, blockchain involves many scientific and technical issues such as mathematics, cryptography, Internet and computer programming. From an application perspective, simply put, blockchain is a distributed shared ledger and database, which has the characteristics of decentralization, non-tampering, full traceability, traceability, collective maintenance, openness and transparency.

These characteristics ensure the "honesty" and "transparency" of the blockchain and lay the foundation for the blockchain to create trust. The rich application scenarios of blockchain are basically based on the ability of blockchain to solve the problem of information asymmetry and achieve collaborative trust and consistent action among multiple subjects.

Share Zone View Network:

The application scope of blockchain technology is still very wide. Based on decentralization, decentralization With features such as trust, collective maintenance, and reliable database, its application in the financial industry is one step ahead.
Blockchain is the underlying technology of Bitcoin, and the application development of blockchain in digital currency is already mature.

Like the blockchain-based trading system development solution provided by Yingtang Zhongchuang, the developed software system has a high degree of security and transparency.

❸ What is blockchain and how to make money with blockchain

Blockchain is an information technologyterminology in the technical field. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "full traces left", "traceable", "open and transparent" and "collectively maintained". Based on these characteristics, blockchain technology has laid a solid foundation of "trust" and created a reliable "cooperation" mechanism, which has broad application prospects.
The ways to make money in the blockchain are as follows:
1. Coin speculation. Coin speculation is like stock speculation. Coin speculation is the lowest threshold for making money in the blockchain;
2. Vendors, district Blockchain is a global market. Like small traders, you can move from a low-price platform to a high-price platform to sell and earn the difference;
3. Earn commissions for promotion. The blockchain method is to register first Exchange account, generate your own invitation link, and then promote it. If someone registers the exchange through your link and generates transactions, you can get a commission;
4. Mining, "mining" in Bitcoin is The accounting process;
5. Technical support, providing blockchain technical support to some teams and enterprises;
6. Opening a trading website and charging handling fees;
7. Developing wallets and wallets It is the infrastructure of the blockchain, just like the "Alipay" or "WeChat Pay" of the blockchain;
8. Be a blockchain project or infrastructure equipment supplier.

❹ How to develop blockchain and how to create a zone Blockchain Development

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software. If you want to learn this programming language, you must first find a good tutorial. Brothers in Arms Go Language + Blockchain Training has recently released a new set of Go language tutorials, and the teacher’s lectures are very good!

As the concept of "blockchain" is being discussed globally, related blockchain technology applications have quietly been added to daily life scenarios such as finance, logistics, credit reporting, manufacturing, and retail. Some experts said that in the future, blockchain will be closely related to people's lives, and the integration of blockchain technology into people's daily lives is the general trend.

The popularity of the blockchain market has triggered a large demand for talents based on blockchain technical personnel, and the popularity of blockchain talents is rising at light speed. According to the “20"Blockchain High Salary List for 2018" shows that domestic corporate giants such as Tencent, Xiaomi, Suning, and JD.com have released many high-paying blockchain job requirements, striving to explore blockchain-related technologies and applications. The list also points out that high-paying positions are divided into The demand for blockchain-related technical positions is mainly high, among which Suning and Keda have given the highest monthly salary of 100k.

Analysis of China’s blockchain industry expenditure scale and application prospects in 2018 in 2019 will receiveNearly US$300 million, solving shortcomings and promoting economic development

Blockchain technology is expected to be widely used in the economic field

Blockchain technology is instrumental in cultivating new drivers of economic growth, building an honest society, and improving management technology It has strong practical significance to improve the financing level and alleviate the financing difficulties of small and medium-sized enterprises, and is expected to be widely used in the economic field. At present, the application of blockchain technology is still in the early stage of development and faces many challenges. We must actively promote the application of blockchain in multiple fields, scenarios and environments of the economy and society, create a good industrial development environment, improve the quality of development, and strengthen Blockchain core technology research and development, professional application demonstration, strengthening standard manufacturing, talent training and the construction of public service platforms.

China’s blockchain market spending in 2019 will be close to US$300 million

According to the “In-depth Analysis Report on Business Model Innovation and Investment Opportunities in China’s Blockchain Industry” released by the Qianzhan Industry Research Institute 》Statistics show that as of 2017, China’s blockchain market expenditure was only US$83 million. In 2018, China’s blockchain market expenditure will reach US$160 million. It is also predicted that China’s blockchain market spending will be close to US$300 million in 2019. At this stage, the overall market size of blockchain is small. This is because most of the blockchain projects on the market are in the experimental stage and the investment is not large. On the other hand, many companies have realized the potential of blockchain and plan to increase their budgets in the future. Affected by this, China's blockchain market will usher in rapid growth, with market expenditures expected to reach US$1.95 billion in 2023. The average annual compound growth rate from 2019 to 2023 is 60.51%.

Analysis of unfavorable factors for the development of China’s blockchain

1. The technology is not mature enough. At present, blockchain technology is not yet mature in terms of system stability, application security, and business models, and cannot meet the requirements of "high efficiency and low energy", "decentralization" and "security" at the same time. First, performance issues. The transaction throughput that can be carried out on the blockchain is not high, and the current block capacity is very small, which leads to network congestion and high-frequency business needs are difficult to meet. Many projects are also working on optimization, but they are far from real scenarios such as banks. There is still a certain distance between the transaction throughput of , stock exchanges, etc. Second, there is the issue of consensus mechanism. In terms of energy consumption, consensus algorithms such as workload proof consume a lot of energy and cost, causing the blockchain to waste a lot of computing power and matching power across the entire network. In terms of types, the current blockchain consensus mechanisms are too few in type and will be diversified in the future. In business scenarios, a richer consensus mechanism is inevitably needed to adapt. Third, security issues. Issues such as privacy protection, harmful information on-chain, smart contract vulnerabilities, consensus mechanism and private key protection, computing power attacks, cryptographic algorithm security, etc. all make the blockchain face a severe situation of platform security and application security. Fourth, database issues. Unlike traditional databases, blockchain shouldUsing a large number of write operations, HASH calculations and verification operations, a database system specifically for blockchain is still a difficulty that needs to be overcome.

2. The application scenario is unclear

Currently, the blockchain project is still in the exploratory stage, and no specific implementation scenario can be found. At present, promising areas include finance, sharing economy, Internet of Things, public services, etc. However, judging from the maturity of existing blockchain technology, there are still many problems in blockchain applications, and there is still a gap between actual use. First, the immaturity of blockchain technology has restricted commercial applications. Although there are currently many types of core blockchain technologies such as privacy protection algorithms and consensus mechanisms, they are generally not commercially available. Secondly, the application model of blockchain is still being explored, and the "irreplaceable" advantages of blockchain have not yet been realized. The blockchain itself represents a consensus system, and a consensus system that conforms to the corresponding business scenario should be built from a higher level, not just "business + blockchain". China has a large number of users, complex business scenarios, and any commercial product will involve a very large traffic and population, and the current blockchain technology cannot satisfy it.

3. Scarcity of professional talents

Blockchain technology is a multi-disciplinary and cross-field technology, which mainly involves operating systems, network communications, cryptography, mathematics, and finance. , production, etc., but currently our country still has shortcomings in interdisciplinary fields and fields, and the supply of talents in related fields is seriously insufficient. On the one hand, there is a huge gap in R&D technical talents. Blockchain technology research and development mainly focuses on programming languages ​​​​such as Go, Javascript, C and C+, and new smart contracts use new functional programming languages ​​​​such as Haskell, Ocaml, and Rholang. There is a huge gap in China's talent market for technical talents with senior R&D experience in relevant languages. On the other hand, there is a lack of design talent at the bottom level. Different from R&D technical talents, blockchain underlying system architecture design talents must master multiple cross-disciplinary professional skills. They must not only have an in-depth understanding of the underlying design principles of blockchain and have experience in the design of various system architectures, but also master the business logic of specific application scenarios. . Although some colleges and universities have launched cross-disciplinary education and blockchain-specific technical disciplines, professional talents are still very scarce.

Analysis of favorable factors for the development of China’s blockchain

1. Favorable policies promote development. In January 2017, the Ministry of Industry and Information Technology released the "Software and Information Technology Service Industry Development Plan (2016-2020)", which proposed requirements for innovation in blockchain and other fields to reach international advanced levels. In August 2017, the State Council issued the "Guiding Opinions on Further Expanding and Upgrading Information Consumption to Continuously Release the Potential of Domestic Demand" and proposed to carry out pilot applications based on new technologies such as blockchain and artificial intelligence. In October 2017, the State Council issued the "Guiding Opinions on Actively Promoting Supply Chain Innovation and Application" proposing to study and use emerging technologies such as blockchain and artificial intelligence to establish a credit evaluation mechanism based on the supply chain.

2018In March 2018, the Ministry of Industry and Information Technology released the "Key Points of the Standardization Work of the Informatization and Software Service Industry in 2018", proposing to promote the establishment of the National Informatization and Industrialization Integrated Management Standardization Technical Committee and the National Blockchain and Distributed Accounting Technology Standardization Committee. In June 2018, the Ministry of Industry and Information Technology issued the "Industrial Internet Development Action Plan (2018-2020)" to encourage and promote the application research of emerging cutting-edge technologies such as edge computing, deep learning, and blockchain in the Industrial Internet.

Since blockchain was first included in the "13th Five-Year Plan" National Informatization Plan in 2016, blockchain has increasingly received attention and attention from the national government. Beijing, Shanghai, Guangdong, Hebei, Twenty-four provinces, cities or regions including Jiangsu, Shandong, Guizhou, Gansu and Hainan have launched dividend policies, launched the layout of the blockchain industry chain, and actively explored industry applications based on blockchain.

2. The blockchain industry is gradually taking shape

At present, my country’s blockchain technology continues to innovate, and the blockchain industry is gradually taking shape, starting in supply chain finance, credit reporting, and product traceability. , copyright transactions, digital identity, electronic evidence and other fields are expected to promote technological changes, organizational changes and efficiency changes in our country's economic system, making important contributions to building a modern economic system. With the continuous influx of entrepreneurs and capital, the number of enterprises has increased rapidly. Blockchain applications will be implemented faster, boosting the high-quality development of traditional industries, accelerating industrial transformation and upgrading, using blockchain technology to "reduce costs" and "increase efficiency" for the real economy, and promote the standardized development of traditional industries. In addition, blockchain technology is deriving into new business formats and becoming a new driving force for economic development. Blockchain technology is promoting a new round of business model changes and becoming an important support for building an honest social system.

3. Broad application prospects in the future

In the past, the circulation of physical banknotes was difficult to trace, but with the application of blockchain technology, the flow of all digital assets can be traced There will be "chains" to check. For example, in the financial field, blockchain is expected to solve the pain points and difficulties in the payment field, reduce the complexity of transactions, increase the end-to-end speed of transactions, reduce communication costs in the transaction process, and improve the transparency and non-tamperability of transaction records. The cost of reconciliation, clearing, and settlement between financial institutions, especially cross-border financial institutions, has always been high, and there are complex manual processes. Blockchain technology has data that cannot be tampered with and is traceable, and its application can help reduce financial costs. The cost of reconciliation and dispute resolution between institutions can significantly improve the processing speed and efficiency of payment business, and also make small-amount cross-border payments possible. In addition, the application of blockchain will also extend to many fields such as medical health, education, charity, social management, etc. The market prospects are very broad.

❻ How to build the main body of the project for blockchain

When it comes to offshore companies, they usually choose to register in the archipelago. Some domestic giants, such as Alibaba, Tengxu, Shanda Network, Xiaomi, Haidilao, etc., have established overseas IPO structures by registering offshore companies in the archipelago.

Advantages of registering offshore companies in the islands:

1. Complete tax exemption (only a small annual management fee is charged)

2. Company information confidentiality (high confidentiality )

3. Overseas IPO structure (domestic giants such as Tencent and Xiaomi build overseas IPO structures by registering offshore companies)

4. Free naming (Chinese can be added)

5. No foreign exchange controls

6. No specific business scope, as long as it does not engage in illegal and criminal activities or industries that require franchising.

2. The Singapore non-profit foundation can later issue relevant legal opinions to ensure legal compliance and prove that the company's operations are in compliance with Singapore's current laws.

The main contents of the legal opinion:

1. White paper modification: Modify the project white paper where it does not comply with Singapore laws and regulations, and a lawyer will issue a professional legal compliance opinion.

2. TOKEN non-securitization certificate: A lawyer issues a professional legal opinion detailing that the tokens issued by the project do not have the nature of securities.

❼ Why 2017 is the most critical year for blockchain

Here are the reasons why 2017 will be the most critical year for blockchain:

Bitcoin’s Enduring Value

Bitcoin, the original tool for blockchain, ended 2016 on a high note, which is a good sign.

Shortly after the new year, "Fortune" reported,

"After experiencing a boom in 2016, the price of Bitcoin has reached $1,000, rising since the beginning of this year. up 120% until recently reaching a three-year high. Reasons including the depreciation of the yuan, the risk of China’s currency controls, and geopolitical instability have all been cited as key factors in the cryptocurrency’s success. Bitcoin’s iconic one Another reason for the year is its retention power - the longer it is, the more familiar it will be, and it will become more like a true store of value."

Whether it's fair or not, blockchain technology The feasibility of Bitcoin is always inseparable from the performance of Bitcoin. If decentralized databases can be successful in finance, they could be used more widely elsewhere. As is customary, the healthy growth of digital currencies has sparked discussions about how to integrate blockchain into new areas. With a healthy Bitcoin, blockchain can expand rapidly in other areas.

Existing Participants

Of course, this has been around for a while, as the blockchain has been firmly tied to Bitcoin . Over the years, many groups have invested heavily in making the technology more widely available, adding new features and creating new applications. If 2017 is to be a great year for blockchain, these existing players must be ready to grow with it.

The symbol of this trend isBefore the end of 2016, the Hyperledger project added eight new members. Software company CA technologies, blockchain project Factcom Foundation, healthcare alliance Hashed Health, South Korea's Koscom, accounting firm LedgerDomain, trading ecosystem developer Lykee, Sovrin Foundation and telecommunications company Swisscom have all joined the project's top 100 list.

The Hyperledger project enters 2017 with an impressive roster of members and plans to introduce blockchain feasibility case studies in real use cases.

New Investments

In a sign of the progress the technology will make this year, companies around the world are laying the groundwork to take advantage of blockchain's status. According to Bloomberg Technology, global companies applied for or accepted 356 blockchain or digital currency-related patent applications in November last year, almost double the number in the first month of 2016.

Marc Kaufman, fintech intellectual property expert at Reed Smith, told Bloomberg:

“We are witnessing an exponential increase in the number of patent applications and we expect that in the next five years we will Seeing thousands of blockchain patents.”

Companies are filing patents at such a rapid pace because blockchain is finally moving from utopia to digital ledger tool, and the number of patents is increasing exponentially With the new discoveries of blockchain, blockchain will enjoy wider legitimacy in 2017.

Only time will tell what the development trend of blockchain will be in 2017, and vice versa, but it is obvious that the status of blockchain technology is visible to everyone, and it also proves that early investors have expectations of its potential, and that new potential may be developed in the future.

Blockchain has also become the darling of the financial community in China and has become a hot topic. All major domestic financial institutions have tested blockchain projects. China Post and IBM collaborated to develop a blockchain asset custody system; Puyin Group launched the tea-based digital currency Puyin.

❽ What does blockchain mean and how to make money

The meaning of blockchain and how to make money are as follows:
1. The meaning of blockchain: Blockchain is a After the information is confirmed by multiple parties, it is finally stored in multiple places. It is a tool that can solve credit problems during transactions.
2. How to make money with blockchain:
(1) Provide blockchain technology services. Form a corporate team to specialize in the development and application of blockchain technology, and provide your technical results to companies in need for use, or develop corresponding blockchain technology based on the needs of service recipients. A simple understanding is to be a middleman.
(2) Use blockchain technology to issue coins. In this way, the enterprise acts as the issuer and publishes a certain number ofInvest a large amount of virtual currencies for others, such as Bitcoin, Litecoin, and Dogecoin. At that time, if you wanted to become an issuer, in addition to having blockchain technology, you also had to apply for a series of filing documents and materials such as business qualification certificates and currency issuance qualification licenses from relevant regulatory authorities. Otherwise, if you don’t have these documents, it would be fraud. . However, successfully preparing these documents will still test the strength and capital of the company. If the funds are not strong enough, it will be difficult to sustain.
(3) Payment for blockchain knowledge. In the early days of the blockchain market, many people did not understand what blockchain was and wanted to participate, which inevitably gave rise to a payment market for blockchain knowledge. Since this year, many public accounts with the theme of blockchain have appeared, and many paid blockchain courses and small investment circles have been born.
(4) Register to receive free candies. Candy is a token that the blockchain project team rewards early users in order to attract more users to join early use and dissemination. Similar to the early "Didi", in order to cultivate a large number of early users, a large number of free taxi tickets were issued to users.
