Lu Zhou was still in his office. At this time, he was thinking that he had been reborn for two years now, and now he had contacted all the two horses and one Li.

The earliest contact was Li Yanhong. At that time, Lu Zhou went to Rebs' dinner in the Beijing group. There were many big guys on the table, and the scarf Lao Cao still impressed him deeply at that time. After that, Lu Zhou and Li Yanhong talked about some products and technical matters through one or two emails, but they didn't contact each other anymore. They took a year and a half.

That's all, after all, each company has something to do. Lu Zhou and Zhang Xiaolong have a good personal relationship, but they rarely contact each other. It's less than twenty minutes away from the university town and the guest village.

Lu Zhou stood up and walked to the bookshelf to get some records of Meng Guyun's past.

Although Lao Ma is here to be a matchmaker, Lu Zhou is so nice to say that he doesn't catch a cold in his heart.

Yunfeng Fund said it was an institution that the big guys invested in with pocket money, and it had no direct relationship with Alibaba, and investments may not be Alibaba-based ecological products. But even if it is a strategic investment, it will take two rounds of backhand before selling its shares to Alibaba. So what do you say?

Emma, ​​Yunfeng made a fortune, and Alibaba took the lead. This abacus was very jingling.

It’s not because Lu Zhou used this to guess Ma Yun’s intention. In fact, the world is dangerous, and you have to be careful of some things.

Even if Mengguyun adopts the A-share structure, the financing can continue to increase control of Luzhou. But if Alibaba comes in, even if it can't control you and acquire you, it's still easy to make some things happen. It's probably the most feared thing about running a business. If the shareholders are not quarreling, the company's serious operations will be affected.

It’s like the Yahoo and Lao Ma in Alibaba are now in trouble and battles. If he has suffered this kind of loss, then you may not be sure that he will learn one or two tricks.

Just like, no one knows how Moyao Zhang Min agreed to sell the shares to Alibaba. There must be other agreements behind this, but the parties involved didn't say it, and no one could know. At least in the end, Alibaba entered Moyao, which is what it wanted.

Lu Zhou thought about it again and didn’t know how Chen Xu would arrange it next. If he could gain an advantage in equity competition during the next round of financing, then as an entrepreneur, he could probably still maintain his position in the company and not be kicked out in the later stage.

Of course, this world is about profit and profit. If Chen Xu wants to get the support of Meng Gu, he will have to pay some price.

He flipped his hands over and over again. After confirming some things, he put the folder back into the bookshelf.

He walked to Meng Xiaoqin's position and said, "I'll go to Seven Stars."

Meng Xiaoqin heard this and said directly, "Okay."

Not much nonsense, this assistant is quite responsible.

Lu Zhou said it so as not to see someone coming soon, and Meng Xiaoqin could communicate with the other party.

After saying that, Lu Zhou left the office, rode his bicycle and rushed to school.

Ye Qingchen has been applying for a driving school for a while. He usually goes to study on weekends. When he is queuing up to take certain subjects, he will take a leave. Occasionally, at night, Luzhou will take her to practice on some roads with few people in the university town.

Look, the night before yesterday, the little girl drove directly to the flower bed on the side of the road. She saw her steering wheel pausing, but in the end she had an intimate contact with the big tree on the side of the road. But tm scared the boat. Fortunately, the speed of the car was not fast, and the airbag bounced out, and nothing happened.

What scares people is not the car crash, but Ye Qingchen's scream.

Oh, Lu Zhou thought, I was afraid that she would have to practice for a long time when driving. It was not that she would not drive if she practiced. There was no emergency, it was okay. When there was a little movement, she would be timid and her courage would be broken. Then she really couldn't drive. Seeing that she was driving, her body was tense, her brows were frowning, and her spirit was nervous. After that, she would not be an old driver.

Yesterday, the car was delivered to repair, and today I can only ride a bicycle to work.

Ten minutes later, Luzhou arrived at the floor where the seven stars of the laboratory building were located. As soon as he passed a laboratory, the hot wind from the door made Luzhou feel a little strange.

Is betago's performance so popular recently? Or does the laboratory add hardware to it? He doesn't know?

The hot air illuminates the full load of hardware. When the laboratory is dissipating heat for the equipment room, the building itself has been built long ago. If there is any explosion of modifications to make heat dissipation, the school will not be able to pass it for a while.

So, I know that the equipment room of this equipment is air conditioning and cooling...

A lot of luxury.

After all, the school also provides many special policies for cooperative projects. Electricity really doesn’t cost much money.

Now this equipment room can be "heated" through the door crack. It seems that air conditioning needs to be added. If it doesn't work, you can only change the place. There is hot air, so the noise is definitely inevitable. Although there are not many people in the laboratory building, it is definitely not suitable to do so for a long time.

Lu Zhou walked into another laboratory, and most researchers were waiting for this, so he walked directly into Lu Ming's office.

Lu Zhou told Lu Ming, "Is the betago progressing recently?"

Lu Ming looked up and saw that it was Lu Zhou, put down the materials at hand and said, "I can't say there is any progress. At present, I have divided several groups to do different work, but the most important chess game training data is still being collected. It is difficult to achieve any results in a short period of time."

Lu Zhou became surprised when he heard this, "Then I see the equipment room running a little full of loads?"

After hearing this, Lu Ming smiled, "Oh, that's when some researchers took some free equipment to mine Bitcoin. I also read the materials, but I didn't have any major problems, so I'll give them a try."

Road boat, "..."

That's a really good researcher...

"Call in and chat?" Lu Zhou said.

Lu Ming also got up and shouted directly at the door, "Xiaocong! Come on!"

Not long after, someone came in the office.

Lu Zhou looked at it and he knew Cao Wencong, the first group of people to enter the laboratory.

Lu Zhou pointed to the chair beside him and signaled him to sit down.

Lu Zhou then asked, "Your boss said that some equipment in the equipment room has been applied for mining. What are your specific ideas?"

He was curious about Cao Wencong's statement. The other party has always had a good impression of Lu Zhou, and he is the type of person with a strong divergent thinking.

Cao Wencong thought for a while, "I only found out about Bitcoin after the New Year. Although the paper is not well written, after thinking about it, I think it can also achieve some results. But I don't know whether it is useful or not."

Lu Zhou was just happy when he heard it, and Cao Wencong's statement was really honest.

He asked, "This is not very good, tell me."

Cao Wencong nodded slightly and said, "To be honest, Satoshi's article cannot be read as a paper. To put it bluntly, he just made a system of ready-made things and wrote an explanation. The key instructions are not well written.

Of course, it is not true that he has not innovated, but I think the key to the problem is that he introduced game theory into the original Byzantine fault tolerance, which is reflected in its incentive and punishment mechanisms.

But this is the creator's intention that I only learned during my use and understanding. Satoshi Nakamoto did not clearly state this part in the white paper, nor did he give it a complete theoretical proof."

Hearing this, Lu Zhou looked at Lu Ming, "What do you think?"

Lu Ming thought for a while, "I took a look and agreed almost. It seems to me that it is also very unexpected. Theories can be made up, if Xiaocong wants to do it. But I think the controversy is certain. After all, a mysterious person who is away from the academic circle has improved Byzantine tolerance for mistakes, and it is difficult to convince others if he says it."

Lu Zhou nodded slightly. It was already early for him to pay attention to Bitcoin, but the real origin is that it was the distribution consistency and Byzantine system discussed with Cheng Xuyuan when he was still in school.

When we talked with Cheng Xuyuan and others on occasion, they often put the Bitcoin issue together with the Byzantine issue.

But they run companies, do not write papers or make any impact.

mport, the proposer of Byzantine problems and the Paxos algorithm, and the big name of distributed systems. Barbara Liskov proposed a small-scale distributed network that meets Byzantine fault tolerance. Several theoretical papers have been written, which are all in the last century. The former will win the Turing Award next year, while the latter was already the winner of the Turing Award as early as 2008.

Speaking of WeChat, some of the memory cloud systems are converted from the Paxos algorithm protocol of MORT.

But you said that a mysterious man put forward something, and the problem solved was that he built a Byzantine fault tolerance algorithm in a large-scale distributed network? The results were comparable to those of two Turing Award winners?

Well, no one dares to believe it when he says it. Even if he listens to Cao Wencong's tone, he can understand it.

Lu Zhou actually knew the development trajectory later. By 1415, some papers began to discuss Bitcoin and put it together with Byzantine fault tolerance. Although the controversy has never stopped, blockchain is an important field, so most people will not jump. Some schools have opened blockchain courses after this, which are mostly related to cryptography and distributed systems.

Luzhou continued, "Okay. Try to do it."

And he also asked curiously, "What's the situation in mining?"

This is all about digging, right? Isn’t it necessary to care? Although Lu Zhou didn’t expect to use the seven-star equipment to dig it out.

Cao Wencong replied, "That's the case. The boss bought another batch of cards before. At that time, I thought that if I could all set up the decks, it would save other hardware costs. After looking for some information, I found that those who did this were miners who mine Bitcoin, so I also formed some multi-card equipment in the middle. If I run AI, the computing efficiency is good, but it is also quite troublesome to make some adjustments to the driver.

Then, if you mining, the computing power of the entire network is about 11t now, and the earliest card for experiments is gtx580. Later, some amds were added, and the entire group had a computing power of about 0.1t.

If you count on a block in 10 minutes, there are about 144 blocks a day, and each block is rewarded with 50 bitcoins. It is probably 144block*50btc*(0.1t/11t) and 65 bitcoins that can be mined in one day.

I dug it for 4 days, and there are about 250. At the moment, it is only about 8,000 yuan per dollar..."

Lu Zhou felt a little funny when he heard his calculations. The equipment in the laboratory was worth millions at least. Although Cao Wencong used idle equipment, he could only be a playful thing if he dug one or two thousand yuan this day. For Qixing, Lu Zhou did not seek to make money. He used equipment to study it and produced any results. The value of the income was far greater than the value of the Bitcoin dug.

After all, laboratory equipment is not used for mining. If you are a real Bitcoin miner, you will consider the cost-effectiveness and then consider the return cycle. This won’t take long, and graphics cards and other things will not be able to mine Bitcoin immediately. This cheap figure is not very meaningful.

Cao Wencong continued, "I can do the archives of things. However, mining Bitcoin should stop immediately, and it doesn't make sense to dig. Maybe I will try running a private chain next, which doesn't require such high performance."

After hearing this, Lu Zhou understood a rough idea. He said to Lu Ming, "You decide whether to establish a blockchain project. At present, the funds and personnel are limited, so we mainly need to promote research on AI."

Lu Ming nodded, "Well. Don't worry, I will grasp this. Xiaocong also has some research significance. I will consider contacting the next school to do distributed projects, which can also save some manpower."

After hearing this, Lu Zhou nodded slightly, and then talked to Lu Ming about ai and betago.

This is his purpose. Cao Wencong can only be an interesting story or an interlude.
