1. What is blockchain and how to introduce blockchain in a simple and easy-to-understand manner

Blockchain is a term in the field of information technology.

Essentially, it is a shared database. 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.

On January 10, 2019, the Cyberspace Administration of China issued the "Blockchain Information Service Management Regulations". On October 24, 2019, during the 18th collective study session of the Political Bureau of the CPC Central Committee, General Secretary Xi Jinping emphasized that “blockchain should be used as an important breakthrough for independent innovation of core technologies” and “accelerate the development of blockchain technology and industrial innovation.” . "Blockchain" has entered the public eye and become the focus of society.

On December 2, 2019, the word was selected into the top ten buzzwords of 2019 by "Biwenqiezi".

(1)Extended reading on blockchain on October 24, 2020:

Blockchain financial application:

2016 Since then, major financial giants have also taken notice and launched blockchain innovation projects one after another to explore the possibility of applying blockchain technology in various financial scenarios. In particular, Puyin Group took the lead in pioneering the “blockchain+” standard digital currency.

The standard digital currency is an asset that has been identified, evaluated, confirmed, insured, etc. by a third-party organization and written into the blockchain through rigorous digital algorithms to form a standard correspondence between the asset and the digital currency. relationship, called a standard digital currency.

In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China’s economy, accelerate the circulation of global assets, and realize the dream of rejuvenation that generations of people have been striving for, Puyin Group will launch in December 2016 Puyin Blockchain Finance Guiyang Strategy Release Ceremony was held in Guizhou on the 9th;

At the meeting, the digital circulation of assets through blockchain, the blockchain financial transaction model, and the relationship between blockchain services and blockchain services will be discussed. The application of social public industries will be discussed. This conference will mark the beginning of the application of blockchain finance and the transformation and development of a new financial ecosystem.

2. Is Bitcoin a conspiracy of the United States?

Please see the video Link below:

Musk’s platform, Wall Street is buying like crazy! Is the Bitcoin surge a US conspiracy?

On March 13, 2021, Bitcoin skyrocketed to exceed US$60,000 per coin. Behind the skyrocketing Bitcoin price, Musk was crazily campaigning for it, while Wall Street and Silicon Valley giants were buying crazily.

For example, the Grayscale Fund I introduced to you before,Currently, it holds more than 650,000 Bitcoins, accounting for 3% of the total Bitcoin supply, with a value of more than 38 billion US dollars. One of the investors behind Grayscale Fund is the famous Wall Street female version of Warren Buffett.

In February 2021, Tesla announced that it had spent US$1.5 billion to buy Bitcoin. In just over a month, the profit may have reached US$1 billion, which is more than the money Tesla made from selling cars in the past year.

The madness on Wall Street has made many people wonder, is Bitcoin a conspiracy by the United States against the big Eastern countries? ? Many media Vs also took the opportunity to exaggerate that the United States is monopolizing Bitcoin, and we must beware of a currency war launched by the United States.

As a blockchain player for 8 years, I have heard similar arguments countless times. After so many years of development of Bitcoin and blockchain, you can still hear such statements. Now that I am doing financial science popularization, I feel that I have an obligation to make this matter clear to everyone. The data sources for this article include Chainalysis, Cryptocompare, Cambridge University Emerging Finance Center, BTC.com, Bitcoin.com, etc. Before the official start, for those who haven’t paid attention, let’s pay attention first.

After I decided to do this issue, I took a look at all the big V opinions on the market about Bitcoin being an American conspiracy, and I summarized it as follows:

Wall Street and Silicon Valley in the United States are buying Bitcoin aggressively. The giants in the United States are platforming Bitcoin in order to attract investors from other countries to enter the sheepfold like sheep and then harvest them. , exchanging the increasingly cheap U.S. dollars in their hands for high-quality assets in other countries.

At first glance it seems reasonable and logical, but what I want to tell you is that these people either don’t understand themselves and are here to deceive the public. , or they understand it themselves, but in order to attract people's attention or for some reason, they insist on confusing right and wrong, telling everyone that Bitcoin is an American conspiracy, and creating panic. If it's the former, it means that you don't understand Bitcoin well enough and you're stupid at most. If it's the latter, it means it's broken.

Let’s put it this way, anyone who tells you that a country or individual can monopolize Bitcoin is a liar. .

In the Bitcoin world, computing power is king. What is computing power? As mentioned before, Bitcoin is actually aA big ledger, everyone can keep accounts, and there are very generous rewards for keeping accounts. Currently, whoever can write down a page in the ledger can get an income of 6.25 Bitcoins. According to Beijing time on March 23, 2021 At 11:15 pm on the same day, the price of one Bitcoin was 359,310 yuan, which is 2.25 million yuan. In addition to this reward, there is also fee income from other people's transfers.

Bookkeeping can earn a high income, so many people want to keep books. How to decide who will do the bookkeeping at this time?

Therefore, each participant has to do a math problem. Whoever solves it first will get the power to keep accounts and get corresponding income.

The characteristic of this math problem is that the forward operation is very simple, but the reverse operation is difficult. It is so difficult that you can only try it one by one.

For example, there are 500 cooking cakes in the two cargo loads of Wuhan University. It is easy to know how many cooking cakes there are in total, but if I only tell you two There are a total of 1,000 cooking cakes in the cargo load. How many are in each of the two cargo loads? This question is not simple. If you are unlucky, you will have to guess hundreds of times before you can guess the right result.

The so-called computing power, simply understood, is the number of times this kind of operation can be performed per second. The faster the operation speed, the greater the probability of calculating the result first. , the greater the possibility of obtaining the accounting rights of Bitcoin.

With the development of Bitcoin, the computing power of the entire Bitcoin network has continued to grow in recent years. It is currently 1.6*10^20H per second, which is equivalent to the global TOP500 The total computing power of supercomputers is 500,000 times.

Whoever can control 51% of the computing power of the Bitcoin network can control Bitcoin. So where is most of Bitcoin’s computing power located? The answer is, China.

According to data from the Cambridge Center for Emerging Finance (CCAF) in April 2020, although China’s computing power share has declined, it is still as high as 65% Above, the second-ranked United States only accounts for 7%, which is close to Russia. China is divided into provinces. One Xinjiang Autonomous Region is equivalent to 5 United States. In terms of Bitcoin computing power, the United States is completely unqualified to say that it starts from a position of strength. Talk to China.

Apart from this, the worldEight of the top ten mining pools are in China, and one of the other two has a founder from China. The only person in the world who has ever controlled 51% of Bitcoin’s computing power is a Chinese. In addition, the world's top three mining machine manufacturers are all from China. Because of this, it is often said that China has a monopoly on Bitcoin mining.

Let’s ask here, if Bitcoin is a conspiracy of the United States, the United States will control Bitcoin Give power to China?

If Bitcoin is a conspiracy, then according to the logic of those big Vs, Americans should suspect that Bitcoin is a Chinese conspiracy.

The second question is, can the United States monopolize Bitcoin by buying Bitcoin and then manipulate Bitcoin? Is the currency price cutting the world's leeks?

In theory, it is possible. And in theory anyone can do it.

This is the composition of Bitcoin trading volume from 2011 to 2018.

Before 2013, Bitcoin transactions were mainly US dollar transactions. With the establishment of domestic exchanges, in 2013 Years later, the RMB dominated Bitcoin transactions, and the pricing power of Bitcoin began to shift domestically. In the red part of the picture, the RMB transaction accounted for more than 80% for a long time. As a result, China also has unparalleled influence on the Bitcoin market.

Until September 4, 2017, in order to prevent financial risks, seven ministries and commissions issued a ban on purchasing Bitcoin with RMB. On September 14, at that time Bitcoin China, a large domestic digital currency exchange, announced that it would stop Bitcoin trading. Bitcoin plummeted 16% that day.

In just half a month, Bitcoin fell from a minimum of US$5,000 to US$3,000, a drop of up to 40%. .

Whether it is more than 90% of the trading volume, or the absolute impact of the ban on the price of Bitcoin , all illustrate the same problem. During this period, the pricing power of Bitcoin belongs to China.

Later, with the closure of a large number of domestic exchanges, the trading volume of Bitcoin and RMB gradually returned to zero. butEveryone should pay attention to the picture. After RMB trading was banned, USDT began to rise.

By the way, USDT is a stable currency. The so-called stable currency refers to their currency value. It is very stable, unlike Bitcoin, which has big ups and downs. USDT is benchmarked against the U.S. dollar, 1USDT=1 U.S. dollar. You may have questions here. If it is so troublesome, why not just use U.S. dollars?

This is a good question. When you can buy and sell Bitcoin directly with US dollars, of course it is more convenient to use US dollars directly. But what if USD trading in Bitcoin was banned?

Combined with the RMB trading volume from as high as over 90% to zero, everyone should know what the rise of USDT means.

As you can see from the picture, although the USDT transaction proportion is lower than the RMB transaction proportion, it still accounts for 60% of the Bitcoin transaction volume. Right and left, and as far as I know, the people who like to trade with USDT the most are Chinese. In other words, so far, the Chinese market still has a strong influence on Bitcoin.

To sum up, whether it is Bitcoin’s computing power China used to be the undisputed number one in terms of ratio and transaction ratio.

However, whether it is the proportion of computing power or the proportion of transactions, China’s voice is constantly declining.

Careful viewers should remember that I said before that although China still dominates Bitcoin mining, its proportion of computing power is declining. , while the shares of the United States and Russia are rising.

This is computing power.

In terms of transaction proportion, after the domestic exchanges were withdrawn, the Chicago Mercantile Exchange (CME) and the Chicago Board Options Exchange (CBOE) in the United States came online one after another. Bitcoin futures,

Intercontinental Exchange, the parent company of the New York Stock Exchange, has also begun to prepare a digital currency exchange.

Enter 2020 years later, Bitcoin began to flow into North American exchanges at an accelerated pace. According to Chainalysis data, in the second week of November 2020, the net inflow of Bitcoins into North American exchanges was as high as 216,000, an increase of more than 7,000 compared to the beginning of 2020. times. In October 2020, East Asia Exchange lost 240,000 Bitcoins.

In other words, in this bull market, North American investors may be the biggest winners. .

Someone once gave an example that may not be very appropriate. It is talking about the cotton market. There is a country that is a producer and has worked hard to produce cotton. , but in the end it has no pricing power.

Facing the same Bitcoin, some people avoid it, some try to surrender to it, some embrace it, and some people keep calling it a scam. It wasn't until the scolding reached 400,000 yuan that I realized that there was no chance of being cheated.

Finally, let’s look back at the question at the beginning, is Bitcoin an American conspiracy?

My answer is that it was not in the past, but it may be in the future.

We once had four great inventions, we once had Zheng He’s voyages to the West, and we once had Ten Thousand Households Feitian, but because we missed the industrial revolution, we were eventually forced to He signed the Treaty of Nanjing, the Treaty of Shimonoseki, and the Treaty of Xinchou. He was called the sick man of East Asia and was humiliated that Chinese people and dogs were not allowed to enter. Have we suffered less from foreigners?

We were once leaders in the blockchain field. Are we going to miss the next technological wave? Are you envious of Americans flying in cyberspace?

If there is a country that can control, monopolize, exploit or destroy Bitcoin, I hope that country is China.

So put aside your prejudices and embrace the future!

3. What is blockchain reform

"Blockchain reform "The concept of "blockchain transformation" began in 2018. On August 5, 2018, the "Chain Reform Action Plan" [1] was released for the first time at the second plenary session of the China Communications Industry Association Blockchain Special Committee [1]. Since then, "Chain Reform" has become a hot word in the circle. Common areas for chain reform include finance, copyright protection, games, government affairs certificates, etc. Since then, the term "chain reform" has begun to be widely seen in news reports, and chain reform has also begun to be widely used in more industries, covering finance, social networking, e-commerce, games, media, retail, energy, agriculture, education, Medical beauty, medical and other industries.

In August, the "Opinions of the Central Committee of the Communist Party of China and the State Council on Supporting Shenzhen in Building a Pioneer Demonstration Zone of Socialism with Chinese Characteristics"[2] proposed to support the development of innovative applications such as digital currency research and mobile payments in Shenzhen. Experts believe that since the launch, trial operation and improvement of digital currencies take time, the pilot launchCome out "sooner rather than later". Shenzhen has the foundation to carry out pilot projects, and the launch of digital currency will greatly promote the development of cross-border trade, especially cross-border trade financing. This major benefit is undoubtedly another positive stimulus for chain reform.

On October 24, the 18th collective study meeting on the development status and trends of blockchain technology emphasized that the integrated application of blockchain technology plays an important role in new technological innovation and industrial transformation. . Blockchain should be regarded as an important breakthrough for independent innovation of core technologies, clarify the main direction of attack, increase investment, focus on conquering a number of key core technologies, and accelerate the development of blockchain technology and industrial innovation. [3] This collective learning is undoubtedly a huge benefit for the entire blockchain industry. It can promote the industry to develop faster, more stable, and healthier from the national level. It is also a great benefit for practitioners in the blockchain industry. A confidence boost. [4]

After the General Secretary’s speech, relevant learning activities were launched across the country. In Chengdu, representatives from the Blockchain Professional Committee of China Communications Industry Association, Sichuan Strategic Emerging Industries Promotion Association, Lianbo (Chengdu) Technology and other related enterprises attended the study meeting [5]; similar seminars were also held in Beijing, Hangzhou and other places. learning activities. It can be seen that chain reform has received national attention.

4. Is the bsn blockchain a national blockchain?

BSN is a formal blockchain alliance chain. On October 24 last year, the blockchain was elevated to a national strategy. At the same level, blockchain was officially included in the “new infrastructure” on April 20 this year, and the blockchain service network was officially implemented as an implementation project in the “new infrastructure”. BSN is led by the National Information Center and jointly constructed by multiple parties. As a global blockchain infrastructure independently developed by my country, it has received strong support from many provincial and municipal governments during its development process, providing BSN with resources such as industry incubation and training bases. facility. At the same time, governments at all levels are also building a local blockchain service ecosystem based on BSN's technical capabilities. For example, recently, the Fujian Provincial Government and the Changsha Municipal Government have directly written BSN into their three-year action plan for new infrastructure. It can be seen that governments at all levels recognize and value BSN. BSN is a cross-cloud service, cross-portal, and cross-underlying framework global public infrastructure network used to deploy and run blockchain applications. It is a very open platform and has gathered many excellent partners. Since being open sourced in 2017, FISCO BCOS has been adhering to the concept of open source and is committed to building distributed commercial infrastructure and working with partners to build a blockchain open source ecosystem. It coincides with BSN in many concepts and ideas. This is also the value and conceptual basis for everyone to finally come together and make FISCO BCOS become the first domestic alliance chain underlying framework that has been officially adapted to BSN.

Legal basis:

October 24, 2020 China CommunicationsThe Blockchain Professional Committee of the Industry Association awarded Xiang Lingyun the Blockchain Industry Leader Award for 2019-2020.

6. Is there any opportunity for the emergence of blockchain public service platforms for movies and TV series in 2020?

It is still due to policy reasons. After the speech on October 24, 2019, Blockchain has become a national strategy, and since then relevant development policies have been introduced across the country. In 2020, it was also proposed to promote the development of the cultural industry. The Fifth Plenary Session of the 19th Central Committee of the Communist Party of China reviewed and approved the "Decision of the Central Committee of the Communist Party of China on Formulating the 14th Five-Year Plan for National Economic and Social Development and the Long-term Goals for 2035". "Recommendation" clearly proposed to build a cultural nation by 2035, pointing out that cultural undertakings and cultural industries should be prosperous and developed, and the country's cultural soft power should be improved. The combination of cultural industry and blockchain has become an inevitable trend.

7. HBA public chain: Create a public chain ecosystem covering blockchain + full-scenario applications

Since the development of blockchain technology, people and even the country have gradually paid attention to it. As a new application model based on computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, and encryption algorithms, the essence of blockchain is a decentralized data storage system that can be updated but cannot be tampered with.

The application of blockchain technology has extended to digital asset transactions, the Internet of Things, commodity traceability, digital culture, digital medicine, network security, medicine and health, etc., promoting social production and life. Major changes in methods and production relations.

The research and development of the HBA public chain began in February 2019. The core team is composed of early overseas blockchain participants and is jointly maintained by multiple decentralized distributed communities around the world. Innovatively proposes the 3R circular economy model (Rece, Renue, Racycle). The token uses the POC+POS mechanism to gradually reward everyone who contributes to the ecology. It will not generate a large number of tokens at no cost like other public chains, and is effective. It has cracked down on industry chaos and ensured fairness for every ecological participant.

HBA has realized a truly decentralized blockchain through a large amount of technology accumulation, developed source code, and established a complete blockchain browser. Users can query the generation of each block and the process of each transaction. It provides a truly fair and open environment in which no one can cheat and everyone can truly become a supervisor of the system.

The ecological application scenarios of the HBA public chain include digital identity, artificial intelligence, supply chain finance, DEFI platform, cross-chain payment, health care, food safety, and education. At present, the development of public chains, blockchain browsers, and decentralized exchanges has been completed. The HBA public chain will be tested on the mainnet in October 2020!

At the same time, there is also a group of spontaneous organizations in the ecology of the HBA public chainWe organize evangelists and professional lecturers to serve the HBA member ecosystem and provide one-stop services such as “incubation, training, and market development” for the HBA ecological community.

Australian, holds senior management positions in multiple chambers of commerce. Started working on blockchain in 2013. In 2014, he applied for the first wallet retrieval patent. In 2015, he went to the government department to teach blockchain. , patent ranking fifth in the world. At the same time, he has his own financial management company in Australia and created the chain33 blockchain underlying architecture. He has a lot of technical reserves and applications, holds BCS and TELC qualification certificates, has published 4 works, and has millions of readers and fans.

In the medical field, we currently face two major challenges: First, the medical system is complex, involving pharmaceutical manufacturers, medical service providers, and patients, etc., so it is necessary to connect all parties and accurately transmit information; second, medical supply The chain lacks traceability. Blockchain technology has the potential to solve the above problems and create new medical models because of its traceability, without the need to coordinate parties, and its high accuracy and reliability.

HBA is based on blockchain technology and combines big data, artificial intelligence and Internet of Things technologies, covering the fields of medical care, medicine, medical insurance, pension, medical equipment, biology, insurance, finance, government and society. public chain.

HBA has rich international medical experience in global new medical health. It can meet the health needs of various users with precise and efficient treatment methods and provide a variety of health-related linkage services. This is because they are very Understand the deficiencies in the current healthcare model. Integrate resources and create a new medical system to solve the problem of difficulty and high cost of medical treatment for the people. We will use 5G technology to efficiently prevent doctor resources from being wasted. With the characteristics of "fast, convenient and accurate" intelligent technology, it provides people with "one-stop" medical and health service solutions.

IPFS, the Chinese name of the Interstellar File System, is a point-to-point distributed file system. It is a hypermedia transmission protocol based on content addressing, versioning, and point-to-point. Its purpose is to supplement or even replace the The traditional centralized storage HTTP protocol has been used for more than 20 years.

The advantages of IPFS are: efficiency, security, privacy, permanent storage, low cost, faster access, etc.

HBA’s block data is stored using the IPFS decentralized storage structure. All blocks have pointer references to the previous block to ensure that the data is not tampered with. The sha256 function is used to hash the data, the ecc asymmetric encryption algorithm is used for identity authentication, the aes encryption algorithm is used to encrypt the private key, and the Merkle number is used to verify and store transactions.

HBA public chain combines distributed storage with the advantages of blockchain, aiming to improve data security,Privacy and user control over their data, while users can receive token rewards for participating in providing storage space.

1) Current status: Under development

2) February 2019: Code open source research and development

3) October 2020: Mainnet Tested online

As an emerging technology, blockchain covers decentralization, trustlessness, sharing economy, distributed computing, distributed storage and other aspects, and will comprehensively innovate existing social system.

HBA public chain has always insisted on advancing with the times, constantly learning new design concepts and development technologies, using the latest design concepts to serve customers and achieve a good user experience. The Internet of Things industry is booming, and only innovative technologies and models can last forever. We firmly believe that innovation is the eternal driving force for human progress. Technology has a starting point, but innovation has no end! Innovation, pragmatism and efficiency will be our eternal pursuit!

8. What exactly will you do after graduating from a blockchain major?

1. What are the employment directions for blockchain technology application majors

1. Technical engineers: including blockchain professionals, such as blockchain R&D engineers, smart contract developers, cryptography experts, etc., as well as traditional Internet technical talents, such as C++/Java/Python development engineers, front-end , backend, testing, etc.

2. Product manager/industry solution expert: The meeting on October 24 last year emphasized the use of blockchain to solve industry problems, people’s livelihood issues, etc. The direction of blockchain application in our country is currently also Most of them are used to improve the pain points of various industries. Therefore, the blockchain industry also has high requirements for product managers. Product managers must not only understand blockchain technology, but also have industry experience or a thorough understanding of a certain industry. Our company calls this kind of product manager an industry solution expert.

3. Product operation: I won’t explain this much. It is similar to product operation in other industries. The premise is that you must have a certain understanding of blockchain technology so that you can quickly get started with the company’s products. 4. There are other positions in other industries such as marketing, branding, finance, legal affairs, etc., and they are also available in the blockchain industry. If you receive an interview invitation for these positions in a blockchain company, it is recommended to do some homework first to understand them. What is blockchain and is it helpful for interviews.

9. What disruptions does blockchain bring and why can it become a national strategy?

The disruptive characteristics of blockchain lie in the following four aspects: 1. Transparency. The data records of the blockchain system are transparent to the entire network nodes, and the update operations of the data records are also transparent to the entire network nodes. This is the basis for the trust of the blockchain system. Since the blockchain system uses open source programs, open rules and high participation, blockchain data records and operating rules can be reviewed by nodes across the entire network., traceability, with high transparency.
2. Openness. The blockchain system is open. Except for the private information of the parties directly related to the data, which is always encrypted, the blockchain data is open to everyone (except for blockchain systems with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the public interface, so the entire system information is highly transparent.
3. Information cannot be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for systems such as private blockchains with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, modifications to the database on a single node are invalid, so the data stability and reliability of the blockchain are extremely high
4. Decentralization. Decentralization is the most basic feature of blockchain, which means that blockchain no longer relies on central processing nodes and realizes distributed recording, storage and updating of data. In a traditional centralized network, attacking a central node can destroy the entire system. However, in a decentralized blockchain network, attacking a single node cannot control or destroy the entire network or more than 5% of the nodes in the network. It's just the beginning of gaining control. 2019 is the first year of commercial application of blockchain technology, and favorable policy incentives will make the development of blockchain technology more stable.
As the application of blockchain technology gradually penetrates into many fields such as digital finance and the Internet, everyone has a clearer understanding of the value of blockchain.
Blockchain has formed a global competition situation. All countries are seizing development opportunities, and China cannot lag behind; therefore, it is understandable that blockchain has become a national strategy.
