❶ What is the life of the man who asked others to buy Bitcoin on Zhihu 7 years ago?

"Force Field" - Public Chain Mining The First Community

On December 21, 2011, a girl asked on Zhihu, "A junior college student has 6,000 yuan on hand. What are some good financial investment suggestions?" On that day, the founder of Babbitt Changchai replied: "Buy Bitcoin, save the wallet file, and then forget that you ever had 6,000 yuan. Look again in five years."

From 2011 to 2018, Bitcoin It once jumped from 3 US dollars to the highest point of 19,000 US dollars. If that junior student bought all 6,000 yuan in Bitcoin, he would already have a net worth of tens of millions. The Zhihu girl who missed out on Bitcoin said she regretted not listening to Chang Chai’s advice to buy Bitcoin. In an exclusive interview with Shenlian Finance, Changchai also expressed regret for answering such a question.

"If I give her another suggestion, I will definitely not suggest any Bitcoin investment." Changchai told Shenlian Finance. "Putting your happiness on the advice of an irrelevant person is not laziness, but stupidity."

1. The civil servant who asked people to buy Bitcoin

In 2010, Liu Zhipeng, who graduated with a master's degree, entered the Land and Resources Planning Institute of the Guangxi Zhuang Autonomous Region and became a civil servant. Here, he participated in the publication of several academic papers on the mineral resources of the Beibu Gulf Economic Zone.

In addition to writing these academic papers, Liu Zhipeng also hangs out on social platforms such as Zhihu and Weibo. On Zhihu, a netizen asked: A junior student has 6,000 yuan on hand. What good financial investment advice do you have? "Buy Bitcoin, save the wallet file, and then forget that you have 6,000 yuan, and look at it again in five years." Liu Zhipeng gave this advice. However, he did not use his real name, but "blockchain", a name that was confusing at the time. Later, the word was translated as "blockchain" in China.

Liu Zhipeng has many pseudonyms. When he wrote science fiction novels, his name was "Chang Chai", which comes from "Lu Lixi with a long chai, Cui Wei with a crown cutting into the clouds" in "Li Sao". Before becoming a civil servant, Liu Zhipeng was already well-known in the science fiction field and had won several awards. But becoming a civil servant seemed to indicate that writing science fiction novels at that time was not a good way out. Later, the name "Changchai" accompanied Liu Zhipeng and moved from the science fiction circle to the currency circle, and his reputation became more and more popular, which was due to the increase in the price of Bitcoin.

Just like his answer on Zhihu, it has become one of the most talked about topics in the currency circle since 2013, with nearly 30,000 likes and more than 6,600 comments, until now There are still many people who left comments under this answer to watch the fun and lament the wealth.Opportunities for wealth are fleeting, and I admire Changchai for being such a great person.

In fact, Chang Chai has recommended Bitcoin to strangers on Zhihu more than once. Among his 118 Zhihu answers, there are four answers recommending Bitcoin. We don’t know if anyone followed Chang Chai’s advice on Zhihu to buy Bitcoin, but what we can confirm is that some people made their first pot of gold because of Chang Chai.

In 2011, Zhang Ming had just been admitted to Henan University of Economics and Law. When he was browsing Weibo, he accidentally discovered an account named Blackbeard Bitcoin. Because he usually likes the anime One Piece, and Blackbeard also It was one of the characters, so Zhang Ming took another look at this Weibo.

In this Weibo, Zhang Ming learned about the existence of Bitcoin for the first time and was immediately attracted to it. After a period of research, during the Spring Festival of 2012, Zhang Ming spent 3,000 yuan of his lucky money to buy Bitcoins from Bitcoin China. “The price of Bitcoins was very low at that time, $5 each,” Zhang Ming told Shenlian Finance. The return on investment was huge. In Zhang Ming’s own words, he just wanted to see if he could make money to buy a mobile phone. As a result, he earned back all four years of college tuition.

Since then, Zhang Ming has been investing in cryptocurrency. While other classmates still rely on the living expenses provided by their parents, Zhang Ming has made millions of yuan in the currency market. It was not until later that Zhang Ming learned that Blackbeard Bitcoin was the Weibo account used by Chang Chai to promote Bitcoin, and it was also his nickname on the Babbitt Forum.

When asked why he recommended Bitcoin on Zhihu, Chang Chai said: "Based on a very simple motive, it is to let more people know about Bitcoin." When writing that answer, Changchai is certain that Bitcoin will definitely rise a lot in the future. The charm of history is: when you look back at the ending, you will see a destined path. It is clear at a glance at which node everyone's destiny met and what changes occurred.

However, at that time, no one could know what the fate would be. After recommending strangers to buy Bitcoin, Liu Zhipeng continued to do his job at the Guangxi Land and Resources Department day after day. In 2013, he and 55 other colleagues obtained the professional technical qualification as an engineer.

2. Wu Jihan gave me my first donation

Chang Chai’s ambition is not in the geological industry. He also has many hobbies, such as writing novels and researching cryptocurrency. But in his own opinion, the number of readers of his novels may not be as high as the number of likes on that Zhihu answer. Chang Chai published his first novel in "Science Fiction King" when he was 16 years old. In 2004, he published his first novel in "Science Fiction World" under the pen name "Chang Chai". In 2006, 2007, and 2008, he won the "Galaxy Award", China's highest science fiction award, for three consecutive years. Hugo Award winners Liu Cixin and Hao Yufang are also Galaxy Award winners.Regular recipient of awards.

To this day, many book fans still mention Chang Chai and his works on social platforms. If he continues to write, we don’t know whether Chang Chai can become the next Liu Cixin, but in Chang Chai’s view, Bitcoin has opened another door to “science fiction” for him.

In 2010, Chang Chai was obsessed with science fiction novels and paid attention to Bitcoin because of his creative needs. As early as 2008, Chang Chai wrote a science fiction novel called "Dragon Slaying Technique". The protagonist is also a hacker, Anonymous. He controls the cloud computing resources on the Internet to help him complete grand computing projects. The concept of "computing is power" coincides with the idea of ​​Bitcoin.

Therefore, when reading the Bitcoin white paper, Chang Chai had a feeling that "the future is already here". At that time, it was the first wave of Bitcoin’s collapse. The titles of media reports were very scary, such as “Bitcoin’s past and present life”, “Bitcoin is dead” and so on. There were mourners everywhere, and they all seemed to be giving eulogies for the final conclusion of Bitcoin. But in Chang Chai's view, these reports are ridiculous. "What others see as a black swan is a gray rhino in my eyes, an opportunity with a high probability of success."

In 2010, Chang Chai I bought my first Bitcoin through Taobao. Recalling the experience of buying Bitcoin at that time, Chang Chai still finds it very funny. “Since there was no quick way to buy Bitcoin in China at that time, my first reaction was what to do if I can’t buy it, and what to do if foreigners don’t sell it. So I told the shop owner that I must Leave the goods for me." While working at the Guangxi Land and Resources Department, Chang Chai had been paying attention to the dynamics of Bitcoin. At that time, the foreign Bitcoin forum bitcointalk was well-known in the circle, but there was no similar website in China.

In 2011, Chang Chai, who had experience in running community websites in college, founded Babbitt, which was China’s first blockchain forum and also Chang Chai’s subsequent entrepreneurial direction. At that time, information about blockchain on the Internet was very scarce. Chang Chai worked tirelessly to translate information and posts from English websites and sent them to Babbitt. His Bitcoin address was also left on the website. One day, a person left a message under the article and said, "Blogger, I think your website is very good. Why don't you apply for an independent domain name and space? I donated 0.168 BTC from your address." People who knew Bitcoin at that time were like As rare as giant pandas are, it is even more difficult to meet people who can exchange Bitcoins in life. Chang Chai is very pleased by the messages and donations from strangers.

After adding the other party’s QQ, Chang Chai learned that the person’s name was Wu Jihan, who was later the founder of Bitmain, an internationally renowned mining machine manufacturer. At that time, Wu Jihan was the bitcointalk Chinese The moderator of the forum. From 2011 to 2014, Changchai maintained a life of working, running Babbitt, and conducting Bitcoin evangelism on Weibo, Zhihu and other platforms. Getting further and further away from science fiction and getting closer and closer to Bitcoin.

"I followed Changchai because I liked science fiction and became a friend of Renren. Around 2011, he talked about the future of Bitcoin on Renren all day long. I thought to myself how this person followed up on MLM. "A friend of Changchai told Shenlian Finance.

3. I regret advising others to buy Bitcoin at that time

"I am going to promote Bitcoin with my real identity. This Weibo will no longer be updated. I will inform you of the new address later. ." At the end of April 2013, Chang Chai was transferred from the Weibo account "Blackbeard Bitcoin" to the Weibo account "Chang Chai". The Weibo avatar is an armored warrior riding a horse. The warrior's right hand holds a long Spear, holding a shield in his left hand, with a "B" for Bitcoin written on the shield.

Since then, the pseudonym "Changchai" has been transferred from the science fiction circle to the currency circle. In the same year, Chang Chai gave three other strangers advice on buying Bitcoin on Zhihu, but it did not attract much attention. This year, Bitcoin repeatedly broke new highs and reached a record high price of $1,242 at the end of the year. At this time, the price of gold was $1,241.98 per ounce, and Bitcoin surpassed gold for the first time.

The Zhihu reply in 2011 was also picked up by netizens and circulated wildly on the Internet. However, since then, Chang Chai has never recommended others to buy Bitcoin on Zhihu. "Actually, I regret answering such a question before." In Changchai's view, because of the myth of getting rich through investment, many people pay attention to the speculative effect of Bitcoin instead of the blockchain and decentralization concepts behind it. This is inconsistent with His original intentions were very different.

Therefore, Changchai never answered similar questions on Zhihu again. Zhihu invited him to participate in several round tables, but he was decisively rejected.

"If I give her another suggestion, I will definitely not suggest Bitcoin investment. Her original choice was the most correct, and poetry and distance are more important. And I don’t think she bought it at the beginning You won’t regret Bitcoin, maybe you will regret it even more, maybe you sold it when it doubled in price, or you lost money when it dropped?”

In Changchai It seems that no one makes a lot of money based on hearsay. The most important thing is to invest in your own brain, otherwise the information will not be visible even if it is put in black and white in front of you.

"Putting your happiness on the advice of an irrelevant person is not laziness, but stupidity."

❷ Read "Blockchain" by Chang Chai and Han Feng : From Digital Currency to Credit Society” Thoughts

You may not know Chang Chai, but you should have heard the story of Zhihu’s divine prophecy: Chang Chai suggested buying Bitcoin. Question posted on Zhihu on December 21, 2011: A junior student has 6,000 yuan on hand. What good financial investment advice do you have? Changchai replied: "Buy Bitcoin, save the wallet file, and then forget that you ever had 6000 yuan, let’s look at it in 5 years. ”

It is precisely because of this divine reply that Chang Chai has gained countless fans. With Chang Chai’s precision and unique vision, coupled with his status as a well-known science fiction writer, in the eyes of ordinary people, he looks like God-like existence.

If you plan to have a more systematic and in-depth understanding of blockchain, reading this book is a good choice. Blockchain technology appeared earlier than Bitcoin, but it was Attention. Blockchain technology is expected to show its talents, especially in the financial field: because the blockchain is non-tamperable, it is expected to further solve the problem of high credit costs in today's society; there are also various innovative Defi projects that have been particularly popular recently, hoping to use the blockchain Blockchain technology is used to change the pawnshop thinking of traditional finance, use technical solutions to solve credit problems, and improve the utilization rate of funds. The author proposes that blockchain is not the revolution of traditional finance. The two should cooperate with each other and learn from each other's strengths. Now the domestic center Digital payment is efficient, convenient and low-cost. However, when it comes to international settlement, it can only be done through the SWIFT organization, which is time-consuming and costly. For ordinary people, they need to open an account in the destination country first. For example, Ripple and BTC It is much more convenient and faster.

❸ What is the blockchain and how to evaluate the blockchain

First of all, don’t think about the blockchain too profoundly. It is a network distributed all over the world. A database storage system that can operate collaboratively is different from traditional database operations - read and write permissions are in the hands of a company or a centralized authority (centralization characteristics). Blockchain believes that anyone with the ability to set up server nodes can participate Among them. Nuggets from all over the world have deployed their own nodes locally and connected to the blockchain network to become a node in this distributed database storage system; once added, the node enjoys exactly the same rights as all other nodes. rights and obligations (decentralized, distributed characteristics). At the same time, people who provide services on the blockchain can perform read and write operations on any node in this system. Finally, all nodes around the world will Synchronization is completed one after another according to a certain mechanism, so that the data of all nodes in the blockchain network are completely consistent.

Blockchain itself is a technology, therefore, it cannot itself be Scams are just like the "p2p" finance that has become popular in recent years. How many scammers use the concept of P2P to illegally absorb public funds and defraud people of their hard-earned money? But is "P2P" guilty? It is just an Internet finance It is just a person-to-person model. It not only creates profits, but also lifts thousands of people out of poverty, achieving a win-win situation for both those who help the poor and those who are being helped. Bihui Digital Currency Trading Platform

Questions The existence of the blockchain cannot hinder the development of the blockchain. The proposal and in-depth research of technologies such as simple payment verification, side chain, and lightning network protocols are already problems that the blockchain can actually solve.

❹ What is the concept of blockchain

Blockchain has two meanings:

1. Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The so-called consensus mechanism is a mathematical algorithm in the blockchain system to establish trust and obtain rights and interests between different nodes.

2. Blockchain is the underlying technology of Bitcoin. It is like a database ledger that records all transaction records. This technology has gradually attracted the attention of the banking and financial industries because of its safety and convenience.

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-transformable. Fake distributed ledger.

Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, and uses cryptography to ensure data transmission and access. It is a new distributed infrastructure and computing method that uses smart contracts composed of automated script codes to program and operate data securely.

❺ Let’s talk about Changsha

Two days ago, Bago, a well-known counter-pointer in the currency circle (all those who are bullish will fall, those who are not bullish will rise) updated a Weibo.

Although I wanted to give him a slap in the face, BTM followed Bitcoin and dropped to the lowest level of 1.7, and now it is back to 2 yuan. But I want to talk about Chang Chai.

The picture that impressed everyone most about Chang Chai must be this picture

But if you search for Chang Chai on the interactive network now, you will find that more than ten years ago he was the most popular person in China. One of the most powerful science fiction novelists. Chang Chai has won the Galaxy Award, the highest award for Chinese science fiction, several times. If he had been writing science fiction novels, he would probably have written The Three-Body Problem soon. ( ͡° ͜ʖ ͡°)✧

The world of Chinese science fiction novels has lost a capable general, but in reality it has welcomed a more sci-fi doer. After fading out of the science fiction world, Changchai and several people founded Babbitt, the most professional blockchain community in China, and became one of the earliest evangelists of Bitcoin and blockchain in China. Because he firmly believes that he is doing things in the future.

I saw a comment from a reader of his science fiction novel on Zhihu. Chang Chai had long asked his readers to buy Bitcoin. At that time, he was still thinking, it’s over, how could a good science fiction novelist start a pyramid scheme? Changchai was already very famous at that time, and he still took the risk of being misunderstood by others to recommend Bitcoin to his readers. However, he still did not buy it. He really regretted it.

Then came 2017, when blockchain technology was booming. After incubating high-quality assets such as neo, metaverse, and quantum, Babbitt finally launched its own blockchain project-Bytom.

Connect the world of bits and the world of atoms.

Do you know what it means? Õ_Õ

Anyway, the first time I saw Byhara’s slogan was in a state of confusion. Is this guy doing pyramid schemes? Such an abstract and high-tech slogan sounds very informal.

Later, I learned about it. Simply put, what Bytom needs to do is put assets on the chain. All real-world assets can be authenticated in the blockchain world and cannot be forged. In this way, the atomic world and the bit world are connected.

This is actually a difficult thing, especially in the current domestic environment, but this must be the direction of the future.

A science fiction novelist uses his own way to bring the future to the present. Sounds pretty cool, doesn't it?

How does Byhara perform? What’s very funny is that Byhara has always been called Adohara in the currency circle.

When other projects spent tens of millions to vote to get on the platform, Adou was criticized for not being listed on Binance.

While other projects were selling Maserati, Mercedes-Benz, and Rolls-Royce on the exchange, Adouyuan was giving away a limited edition Bywon 6S mobile phone case in a lottery.

When other projects repurchase and burn or airdrop to currency holders, Adouyuan locks the repurchase and is reluctant to give any benefit to the currency holders.

But the weekly report is never absent, and Byhara’s progress can be seen in it. The project on github is also progressing smoothly.

I really like this kind of weird team.

I don’t pull the dishes, I don’t cut the leeks, when the tide goes away, I will be a good person.

❻ What does blockchain mean and how to understand it

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of related data generated using cryptography methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block.

Notes

1. Blockchain Originated from Bitcoin, on November 1, 2008, a person claiming to be Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which elaborated on P2P network technology, encryption technology, The architectural concept of electronic cash systems such as timestamp technology and blockchain technology marks the birth of Bitcoin.born.

Two months later, the theory came into practice, and on January 3, 2009, the first genesis block with serial number 0 was born. A few days later, block number 1 appeared on January 9, 2009, and was connected to the genesis block number 0 to form a chain, marking the birth of the blockchain.

2. 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 have been striving for, Puyin Group launched the On the 9th, a Puyin Blockchain Finance Guiyang Strategy Release Ceremony was held in Guizhou. At the meeting, the digital circulation of assets through blockchain, the blockchain financial transaction model, and the application of blockchain services and social public industries will be discussed. Start a discussion.

❼ How Liu Cixin, Chang Chai and Ji Shisan "crossed borders" in Wuzhen

The news came out that Liu Cixin, the author of "The Three-Body Problem", confirmed to attend the World Blockchain Conference (Wuzhen) , immediately hit the circle of friends, and the "cross-border" branch venue also attracted much attention. Fans could no longer contain their excitement and were eager to know more. Today we are going to find out and take you closer to this mysterious "cross-border".

The big names attending the "cross-border" sub-venue include:

Chang Chai

Founder of the Future Affairs Administration, CEO of the Future Affairs Administration, Guoke Co-founder of .com, science fiction author, science fiction science event host, and founder of the Asia Pacific Science Fiction Conference. A former Xinhua News Agency reporter for ten years, he is good at reporting in the field of science and technology. He has won the China Journalism Award, the American Association for the Advancement of Science Young Science Journalist Scholarship, and the Chinese Academy of Sciences Science Star Award.

On the afternoon of June 30, Chang Chai and Da Liu will have a conversation. The two Galaxy Award winners will compete with each other, so remember not to blink! Ji Shisan’s speech sharing is equally exciting. Is it as unique as his personal experience? Xiao Lei will announce his outlook for the market in the second half of the year at the scene. Will he succeed in predicting it again? At the same time, we were fortunate to have Ji Shaoting as the host. After 10 years as a media person, she transformed into a goddess in the science fiction world. The scene when she regained the microphone is worth remembering.

What kind of wonderful chemical reaction will "science fiction + blockchain" produce? Let us enter the science fiction world in the blockchain, think together, and see the future together!
