Looking back on 2009

Chapter 25 Sail (please recommend and collect)
Lying on the bed in the rental house, staring at the ceiling above his head, Chen Zhihe's mind was extremely clear.

Life needs to pause, review and summarize, and then move forward.

Some things need to start planning ahead.

Chen Zhihe thought of Bitcoin.

In 2008, Satoshi Nakamoto published the Bitcoin white paper on a little-known cryptography mailing list.

The white paper proposes a new financial system that replaces the role of banks and third-party payment processors:
"Purely peer-to-peer electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution."

2009 1 Month 3 Day.

Satoshi Nakamoto mined the Genesis block, also known as block 0, on an ordinary computer. At this time, there was no competition with other miners.

The next block, Block 1, was not mined until 6 days later, on January 1.

It has only been half a year since Bitcoin actually appeared on the Internet.

In other words, the current Bitcoin has only just emerged.

Although Chen Zhihe is not clear about the specific details, at least for now, Chen Zhihe has not found any information about Bitcoin on the Internet.

However, it is also officially so that he can have the opportunity to seize the opportunity.

Bitcoin in 2009, in China, this is an amazing blue ocean that is unknown.

Chen Zhihe had a preliminary idea.

First, he needs to figure out how Bitcoin works.Then, advertise and promote Bitcoin online.As a pioneer, there is always an incomparable advantage.

Just do it, he searched for information about Bitcoin on the Internet.

Fortunately, Google was still available at this time. Chen Zhihe downloaded Satoshi Nakamoto's Bitcoin white paper from the Internet and decided to study it carefully.

Fortunately, Chen Zhihe's English is not bad, otherwise, he really wouldn't be able to read the white paper in English.

However, even so, many professional terms are daunting, and Chen Zhihe can only guess.

In particular, there is a large section of code describing the blockchain calculation process in the white paper, and Chen Zhihe is completely dazed.

Sighing, Chen Zhihe admired those who can discover the potential of Bitcoin in the early stage.

At this time, Bitcoin is not even a bud, not because of curiosity and enthusiasm, who would pay attention to it.

A long way to go.

Chen Zhihe did not give up, he decided to learn C language by himself first, because the examples in the white paper are written in C language.

Fortunately, there are many computer language training courses at this time, especially near universities.

As one of the best universities in the province, Jiang University is even more so.

As a law student in the past, Chen Zhihe didn't pay attention to this, but he often passed by the school, and he probably knew where such training classes were located.

After going out, relying on his memory, Chen Zhihe came to the training street at the entrance of Jiang Dazheng.

In addition to computer training, there are more English and accounting training.

It was still daytime, and Chen Zhihe walked into a store with a signboard saying "Zhiyuan Computer Training".

The training institution is on the third floor facing the street, and the signboard is hung by the window facing the street with an LED screen.

When I walked in, I saw that the environment was average, with plastic stools and computers with big butts, which was worse than the environment of Internet cafes.

Chen Zhihe didn't care about these things.

Just as Chen Zhihe walked in, a student-like man with glasses greeted him: "Student, do you want to learn computer?"

Chen Zhihe nodded, walked inside and looked around, there were not too many people, and asked the man with glasses who was following him: "Do you teach C language?"

The man with glasses was taken aback: "C language? Are you a computer major?"

Chen Zhihe shook his head: "No, it's purely a hobby."

"Teach me, but I can teach." The man with glasses looked at Chen Zhihe carefully: "I thought you came to learn computer first-level and second-level, and our main purpose here is to train this. Did you have the foundation before?"

"No foundation, no experience." Chen Zhihe said.

After listening, the man with glasses glanced at Chen Zhihe: "I don't know where you heard about the C language, but let me tell you that the C language is outdated, and I will push you to learn JAVA. From a professional point of view, JAVA is the only is the best computer language."

The man with glasses said this, a little excited.

At this time, a tall and thin man came out from the inner compartment, and stopped when he heard the man with glasses passing by, "Tan Song, repeat what you just said, what is JAVA is the best computer language?"

"JAVA is the best computer language in the world."

"Fart, that's Python," the tall thin man retorted.

The two talked to each other, and it looked like they were about to quarrel.

Chen Zhihe was speechless, and interrupted them: "Can you teach me? I'm going to learn C language."

The two who were arguing stopped, looked at Chen Zhihe together, and wanted to say something more.

At this time, when I heard the quarrel outside, a girl came out from the inner compartment. She had short hair and a normal appearance, but she was wearing a pair of thin-rimmed glasses.

"I said what are you two arguing about? This is a training class." The girl scolded the two boys, then turned to look at Chen Zhihe.

"We don't offer courses in C language. We mainly focus on computer first-level and second-level courses, but we can also teach C language. May I ask, what is your main purpose of learning C language?"

Chen Zhihe thought for a while, and replied: "I hope I can understand the C language code, and then I can create a forum. Of course, the former is the main thing."

"Then I think you can learn C language, but it might be difficult to make a forum with zero foundation." The girl shook her head, "If it's a simple forum, we can help you build it, and you can maintain it yourself later. It doesn't cost much."

Chen Zhihe thinks it makes sense, there is nothing wrong with professional people doing professional things.

Nodding his head, he said, "How much?"

The girl said frankly: "No one who comes to us wants to learn this. Generally, students majoring in computer science can learn it in the school they want to learn. Those who are not majors in this field are not interested. If you really want to learn, I can give you some For the textbook, you learn it by yourself, if you don’t understand it, ask me again, and the fee will be 1000 yuan until you finish studying.”

Turning around, the girl whispered to the two boys again.

The man with glasses said: "General forums are very simple. If you use JAVA, I will only charge you 2000 yuan. But if you want to maintain it later, you'd better learn JAVA."

Not to be outdone, the tall and thin man glanced at the man with glasses, and said to Chen Zhihe, "As long as you learn Python, I will only charge you 1500."

Seeing that the two were fighting again, the girl put her hand on her forehead with a headache on her face.

Chen Zhihe didn't feel disgusted, he was a technical man, he insisted on his own ideas without giving in, not to mention that he was so cute.

"I only learn C language, and the forum must also be written in C language, so you don't have to persuade me, I naturally have my own reasons."

The two wanted to fight again, but were stopped by the girl.

"I'm in charge. For 2000 yuan, we will build a forum for you. You can tell him your request later." After speaking, the girl pointed at the man with glasses.

The two of them didn't speak, they just looked at Chen Zhihe with a look of regret, as if they were looking at a Xiaobai who had gone astray.

Although Chen Zhihe doesn't understand computers, he knows how to bargain.

After much arguing, Chen Zhihe's tuition fee was set at 800, but they had to be asked to help make the forum, and the price was 1700.

The girl's name is Wang Yanan, and the guy with glasses next to him is called Chen Chen, Chen Zhihe's family member, and the tall, thin guy is called Lei Jun.The three of them are all junior students of Jiang University's School of Computer Science. They will soon be seniors and have no more classes, so they took advantage of the summer vacation to jointly open such a training institution outside the school.

Hearing the name Lei Jun, Chen Zhihe looked at Slender and Tall a few more times, what a good name.

Are you OK?
……

The two sides negotiated, but Chen Zhihe didn't pay the money immediately, but just told the other party that he would come back the next day.

……

　I hope you can vote more and collect it.
