『一』What is the essence of blockchain

From an academic perspective, blockchain is distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. New application models of computer technology. Blockchain is essentially a decentralized database.

For example, if you are a woman, every time your boyfriend says something disgusting to you or promises to buy you something, you immediately record it and send it to all of your and his Best friends, classmates, colleagues, and various groups and circles of friends make it impossible for him to deny it anymore. This is called blockchain.

The core advantage of blockchain technology is decentralization. It can realize based on data encryption, time stamping, distributed consensus and economic incentives in a distributed system where nodes do not need to trust each other. The point-to-point transactions, coordination and collaboration of decentralized credit provide solutions to the common problems of high cost, low efficiency and insecure data storage in centralized institutions.

『二』 "A man plays a woman and a woman disguises herself as a man" in Shakespeare's play

Disk observation

As of the close, the Shanghai stock index It reported 2954.18 points, down 0.87%, the Shenzhen Component Index reported 9746.13 points, down 0.57%; the Chuang Index reported 1686.58 points, down 1.05%. Looking at the market, blockchain, pork, and animal vaccines were at the top of the list of sector gains, while semiconductor, 5G, and unmanned retail sectors were at the top of the list of declines.

Outlook

In Shakespeare's period, women were not allowed to appear on the stage, and all female roles had to be performed by male actors. If you read Shakespeare's works, you will often find plots like this: the female characters in the plays often accompany women in men's clothing. The reason for doing this is because this way the boy can perform with ease. After all, the actor and the screenwriter are friends who get along day and night. Would it be confusing as an audience at the time? Watch a male actor play a woman, and this "woman" is accompanied by a man dressed as a woman. I don’t know if the audience was confused at that time, but investors in the past two days should have this feeling about the concept of blockchain.

Blockchain and digital currency have been a bit like this in the past two days. The stocks with the concept of blockchain are dressed up as digital currency, acting out the story of blockchain or digital currency. In short, what concept is influenced by The role played by the popularity is confusing to investors. In just one day, the concept of blockchain has become more serious. At present, some strong stocks can continue to maintain a strong rise, while some hot stocks have adjusted early. Blockchain and digital currency are actually two different concepts.

Li Wei, Director of the Science and Technology Department of the People's Bank of China, said at the Bund Financial Summit: "Blockchain, as an important emerging technology, has great potential in promoting the innovative development of the digital economy." At the same time, the Foreign Exchange Administration We are promoting the application scenarios of blockchain technology and artificial intelligence in cross-border trade financing and macro-prudential management.. Blockchain technology can solve the pain points caused by the inauthenticity of information in the physical industry. For example, in the mining industry, due to frequent falsification of early exploration documents, it is difficult for the mining industry to obtain loans from banks. “If the blockchain can be combined and the three parties involved in the early stage of exploration—the supervisor, the survey team, and the commissioned exploration team—all enter the blockchain chain, the credibility of the early stage exploration will be greatly improved, and it will also enable enterprises to base their exploration on The right to obtain financing from financial institutions. This is an example of blockchain promoting the transformation of the real economy. These are applications of blockchain technology. At present, many things are still in the trial stage. Subsequent applications to certain companies will still make profits. There is a long way to go. At this stage, we believe that for those companies that follow the trend and say that their main business is related to this hot spot, it is better for investors to pay attention to risks.

Operational Strategy

In the short term, the blockchain industry may gain more attention from the application perspective, but the basic technology and security governance industries that receive less attention may become more cost-effective investment directions.

『三』Female scientist Duan Sisi: "Both hands fighting" behind the blockchain "jianghu"

Duan Sisi works as a researcher at the Institute for Advanced Study, Tsinghua University. (Photo provided by interviewee)

Duan Sisi works as a researcher at the Institute for Advanced Study, Tsinghua University. Place where she works She has very few things, and her equipment is only three computers. The strange and dangerous offensive and defensive advances and retreats are only brewed in her mind and deduced on the keyboard, and there is no trace of "gunsmoke".

Her The research direction is "Byzantine Fault Tolerance Algorithm", which aims to prevent the network collapse of each node in the distributed system due to "enemy destruction". To put it figuratively, she is conducting a high-intelligence "hands-on-hand game". The first step, Imagine a possible loophole or "enemy"; the second step is to find a way to make the "enemy" ineffective; the third step is to convince peers that she is solving a "real problem".

Duan Si Si defines herself this way: between a scientist and an engineer. She does not directly "fight" with hackers like a network engineer. She uses the power of mathematics and logic to set rules that make the "enemy" powerless.

"There are bandits among us. "Duan Sisi used the term "killing game" to compare the "Byzantine Generals Problem" she studied. "The bandit spreads false news and misleads the good people's judgment, and the battle will naturally be lost. What I want to do is create a protocol that ensures that even if there are gangsters, the good guys don't lose. ”

When the “Byzantine Generals Problem” was proposed in the early 1980s, no one knew what blockchain was. It is the continuous research on this issue that supports today’s blockchain Blockchain technology. Now, China has regarded blockchain as an important breakthrough for independent innovation of core technologies.

At the beginning, Duan Sisi choseThe direction was a bit unpopular, and people who didn’t know what it was about thought it was solving Mathematical Olympiad problems. She also encountered rejections from scientific journals. After the rise of blockchain, people saw the importance of network security protocols, and her academic achievements were seen by more people.

In January this year, Duan Sisi was selected as one of the "35 Technological Innovators Under 35 Years Old" in China in 2021 by MIT Technology Review. The reason for the award was that she proposed multiple industry-leading Byzantine fault-tolerant protocols. , achieved outstanding results in the fields of distributed systems, blockchain and applied cryptography.

Riding the fast train of emerging technologies, Duan Sisi said that he was quite lucky, but the explanatory power of luck is limited after all. There were not many female classmates during her master's and doctoral studies, and most of them did not continue their academic careers. The reason that supports her in not giving up is "it's quite interesting."

What makes Duan Sisi interesting is the various tricky questions she has come up with. In her opinion, discovering problems is sometimes more important than finding answers.

“Sybil attack”, “hard fork”, “Merkle tree”, “asymmetric encryption”… When asked to popularize these “black words” in the blockchain circle, Duan Sisi was like: When you press the answering machine during a quiz show, you think quickly, speak quickly, and explain the questions quickly.

Duan Sisi studied in the Department of Electrical and Electronic Engineering at the University of Hong Kong. He received his PhD in Computer Science from the University of California, Davis, in 2014. After graduation, he worked at the Oak Ridge National Laboratory and the University of Maryland. The whole family will return to China in 2020.

"I feel that domestic development is fast and the pace of work is also fast. I am more eager to develop in this aspect, especially in the computer field, although it will be tiring." She said.

Young and promising, with an interesting career and a happy family, people around her say she is a "winner in life", but she thinks her life is "a piece of cake". She is the mother of two boys, aged 6 and 4. She once held her baby in one hand and wrote code with the other.

She refuses to give up when she is young and can’t stop doing what she wants to do. This is also reflected in her work style. "Others can write code piecemeal, but I am used to writing it in one go."

To solve a Duan Sisi-type problem requires writing tens of thousands of lines of code, which takes at least several months of work. What this "scientist with a baby" desires most now is a chunk of time. "Once you are interrupted, you will forget what you were thinking when you come back," she said.

Duan Sisi shared an experience about "time management": If you encounter something that can be solved within 5 minutes, then solve it now. It will definitely take more than 5 minutes to put it off later.

『四』To seize this trend, Tong Liya and Gao Xiaosong joined the "3 O'clock Sleepless" group, but Han Geng was kicked out

Recently, a "3 O'clock Sleepless" blockchain "group" (hereinafter referred to as the 3-point sleepless group) is inIt’s hot in the investment community!

According to China Entrepreneur Magazine, Sequoia Capital Shen Nanpeng, 360 Chairman Zhou Hongyi, angel investors Cai Wensheng, Xue Manzi and other investment circles are in this group, and even Gao Xiaosong, Tong Liya , Lin Yoona, Han Geng and other stars.

This WeChat group, created on February 11, reached the upper limit of 500 members in less than a day. During the Spring Festival, it is said that the total amount of red envelopes in this group reached one million. However, this is not the main motivation for celebrities and big shots to join the group. It is even forbidden to publish information such as currency speculation and ICO in this group. People in the group mainly learn about the application prospects of blockchain technology.

I noticed that according to the definition of "China's Blockchain Technology and Application Development White Paper" issued by the Ministry of Industry and Information Technology, blockchain is a computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Innovative application models in the Internet era.

Blockchain technology is considered to be a disruptive innovation in computing models after mainframes, personal computers, and the Internet, and is likely to cause a new technological innovation and industrial change on a global scale.

Today, with the price of Bitcoin “cutting in half” from its peak, and the strict supervision of countries such as China, the craze for “virtual currency” has begun to dissipate. However, as the underlying technology, blockchain is expected to be widely used in finance, supply chain management, manufacturing, Internet of Things and other fields in the future.

The group once distributed over one million red envelopes in seven days

The "3 O'clock Sleepless Blockchain Group" was originally founded by Yuhong on February 11. Yuhong had previously He is the main person in charge of 360 Games and is now the founder of SEEU & QYGAME, which launched the large-scale online game "Basic World" based on blockchain.

Since it was three o'clock in the morning when the group was first established, it was named the 3 O'clock Sleepless Blockchain Group.

In this WeChat group, known as the No. 1 blockchain information group, there are Sequoia Capital Shen Nanpeng, 360 Chairman Zhou Hongyi, angel investors Cai Wensheng, Xue Manzi, Fenbushi Capital partners Shen Bo, and even stars such as Gao Xiaosong, Tong Liya, Lin Yuner, and Han Geng.

Xue Manzi, Li Xiaolai, Chen Weixing, Shuai Chu and others are the earliest participants of the blockchain. Xue Manzi invested in Quantum Chain, Bytom Chain, and Mo Chain. Li Xiaolai is the first person in China to invest in Bitcoin and Ethereum. Chen Weixing also has his own fund and has invested in projects such as Huobi, Binance, and Tron. Shuai Chu is the founder of Quantum Chain.

InterestingHowever, the one who received the warmest welcome among those who joined the group was not the industry boss, but the film and television star Tong Liya. It is said that after Tong Liya was added to the group, there were hundreds of messages welcoming her to join. Tong Liya said that she is still a beginner in blockchain and hopes to learn more, and attached a big red envelope of 8,000 yuan.

Some inactive people in this group will be kicked out, such as Han Geng, No. 1 Matchmaker founder Mu Yan, Meitu CEO Wu Xinhong, etc. Those who remain in the group often engage in intense “mutual” discussions, and there are also some new members who are thirsty for knowledge and quickly absorb fresh knowledge about the blockchain.

On February 24, Chen Weixing in the group and Zhu Xiaohu, managing director of Jinshajiang Venture Capital, had a "mutual fight" around the blockchain.

The cause of the incident was that Zhu Xiaohu forwarded an article about blockchain in his circle of friends and said not to include him in various 3 o'clock groups. There are some outlets that he would rather miss and some money that he would rather not make. Otherwise, the late holiday will not be guaranteed.

This statement immediately aroused Chen Weixing's refutation. Chen Weixing asked, is the method of cutting leeks in equity investment more advanced than that in the currency circle? Is the bubble in the entire blockchain industry as high as the global stock market bubble? Zhu Xiaohu responded that ICO, a model that tests human nature, has never been successful.

Don’t talk about currency speculation, just talk about blockchain

Yuhong and the first industry tycoons Xue Manzi and Chen Weixing to join the group jointly set rules in the group: It is strictly prohibited to post news about currency speculation, ICO, etc. in the group. Therefore, the main topic of group chat is the application of blockchain technology.

Guo Hongcai is a well-known figure in the currency circle. He doesn’t know much about blockchain technology, but he became a rich man through currency speculation. He was kicked out of the group for the second time because he said in the group, "I'm here to make money anyway. Talking about technology is really meaningless... The biggest application of blockchain is currency speculation." After being kicked out, Guo Hongcai was unconvinced and sulked in another group, "They never talk about making money, they are too vain."

China has always been at the forefront of regulating virtual currency speculation.

In September last year, China completely banned the domestic Bitcoin trading platform business. This regulation also has an impact on global Bitcoin transactions.

On February 5 this year, the People’s Daily published another article discussing “currency speculation” and believed that all countries should strengthen coordinated supervision to prevent systemic risks.

The People's Daily stated that in recent times, various conferences and exchange activities with the themes of blockchain, digital assets, and virtual currencies have emerged in an endless stream, and "coin speculation" has become a "currency speculation".Upsurges such as "ICO" are also coming one after another. Some people join the "coin speculation army", hoping to obtain huge returns through short-term speculation. Since blockchain and virtual currencies can transcend national boundaries, countries should strengthen coordinated supervision to prevent virtual currency transactions Triggering systemic financial risks.

This is exactly:

The virtual currency is speculated to the sky,

A series of sudden rises and falls.

Beat the drum and spread the flowers, blow the big bubble,

There is an urgent need to regulate the cloud.

The application prospects of blockchain are broad

According to the white paper of the Ministry of Industry and Information Technology, Blockchain technology originated from the foundational paper "Bitcoin: A Peer-to-Peer Electronic Cash System" published in 2008 by a scholar with the pseudonym "Satoshi Nakamoto".

In a narrow sense In other words, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is a cryptographically guaranteed distributed ledger that cannot be tampered with or forged.

Currently, blockchain technology is hailed by many large organizations as a major breakthrough technology that completely changes the way business and even organizations operate.

The widespread application of blockchain technology can make " "Decentralization" can be realized at low cost.

When we send an email, what the other party receives is actually a copy of the email, which allows the information to be spread quickly. But this approach cannot be copied Apply it to financial and other fields. For example, when you pay 100 yuan to the other party, you cannot copy and paste the 100 yuan currency in your hand to the other party.

Therefore, in today's society, when it comes to cash, When trading , securities, intellectual property, patents, carbon emission quotas, etc., you must rely on a huge central institution (bank, third-party payment platform, etc.) to solve the problem of trust, which will increase transaction costs and slow down transaction speed. For example We can send an email in a minute, but a transfer across the city can take days. Moving money from one country to another comes with high fees.

Canadian blockchain expert Don Tapscott believes that blockchain technology will change the world and make trust-building technology simple and easy to understand. He said that the popularity of blockchain technology means that we may no longer need to be powerful in the future. central institution as a credit medium. This is the next generation of the Internet, which will likely change ourMoney, trade, government and society.

『五』What is blockchain? A cartoon to help you understand (a must-read for beginners)

The word "blockchain" was actually used in the early cryptography circles , the underlying technology of Bitcoin is called "Bitcoin". In English, Bitcoin starting with a capital B refers to the network system or network protocol of Bitcoin.

However, due to public confusion, people are now very resistant when talking about Bitcoin, thinking that Bitcoin is synonymous with illegality, scams, pyramid schemes, and another phenomenal bubble in Internet finance! As a result, people had to merge all the underlying technologies (timestamps, proof-of-work mechanisms, etc.). In order to distinguish them from Bitcoin, they renamed them Blockchain, which translated into "blockchain". This is how the term “blockchain” appeared.

Blockchain is not a single technology, but a collection of a series of technologies.

How should we understand blockchain? Let’s first use the love story that everyone loves to talk about as a simple example. Establish a simple blockchain model, then the following situation will occur when falling in love in this blockchain model:

In the future, all men and women of the right age will fall in love and the entire process of marriage commitment will be blocked by all other men and women of the right age. Consensus, all the stories that happen between two people will form a block.

All other men and women are the chain. If a third party intervenes or you violate your partner, others can see it, and you will never find a partner in the future.

To be precise, the blockchain is a "full center" system, that is, every node on the chain is the center.

Trial marriages for men and women to fall in love, post on friends, show affection, promise to love each other for a lifetime and be known by all other marriageable men and women are the applications of blockchain. If one day one party breaks their promise, don't think that deleting the photos will be useful, because everything is recorded by all marriageable men and women.

Cannot be deleted or changed, this is blockchain technology.
