MTL - Internet 2010-Chapter 390 Mined 0 coins
Lu Zhou was still in his office. At this time, he was thinking, it has been two years since he was reborn, and now he has been in contact with two horses and one Li.
The earliest contact was with Li Yanhong, at that time it was Rebs' dinner in the capital group that Lu Zhou went to. There were also a lot of bigwigs on the table, and Lao Cao in the scarf was still quite impressed at the time. After that, Lu Zhou and Li Yanhong talked about products and technologies through emails once or twice, but they didn't get in touch after that, and it took a year and a half to get together.
That's how things are, after all, their respective companies are busy with work. Even Lu Zhou and Zhang Xiaolong had a good personal relationship, but they rarely communicated very often. The University Town and Kecun were only less than 20 minutes away by car.
Lu Zhou got up and walked to the edge of the bookshelf to fetch some Mengguyun's past records.
Although Lao Ma came to be a matchmaker for the matchmaking, Lu Zhou, who said it nicely, didn't feel too cold in his heart.
Yunfeng Fund said that it is an institution that the bigwigs spend their pocket money to invest in. It has no direct relationship with Ali, and the investment is not necessarily all Ali-based ecological products. But even if it is a strategic investment, it will take two rounds of backhands to sell the shares to Ali, so what can I say?
Emma, Yun Feng made a lot of money, and Ali came to pick up a plate. The abacus played like a jingle.
It's no wonder that Lu Zhou used this to speculate on Ma Yun's intentions. In fact, the rivers and lakes are dangerous, and you have to guard against some things.
Even if Mengguyun adopts the AB share structure, the next financing can continue to increase the control of Luzhou. But let Ali come in, even if it can't control you or acquire you, it's still easy to stumble on some things. This is probably the most fearful thing about running a business. The noisy and noisy among shareholders will affect the company's serious business operations.
It's like Ali's Yahoo now. The old horse has been through things and battles. He has suffered such losses, so you can't guarantee that he will also learn a trick or two.
Just like, no matter Lu Zhou or Chuangmeng, no one knows how Mo Liao Zhang Min agreed to sell the shares to Ali. There must be other agreements and activities behind the scenes, but no one can know if the parties do not say it. At least as a result, Ali entered Mochao, which is what it wanted.
Lu Zhou thought about it again, and didn't know what Chen Xu, the current CEO of MoLiao, would do next. If he can gain an advantage in the equity competition in the next round of financing, then as an entrepreneur, he can probably keep his position in the company and not be swept out in the later stage.
Of course, this world is all about benefits. If Chen Xu wanted Menggu's support, he had to pay some price.
He turned it over and over in his hand, and after confirming something, he put the folder back on the bookshelf.
He walked to Meng Xiaoqin's place, "I'm going to Seven Stars."
Meng Xiaoqin heard it and said directly, "Okay."
Not much nonsense, this assistant is quite the duty.
And Lu Zhou said it so that no one would come over, and Meng Xiaoqin could communicate with each other.
After all, Lu Zhou also left the office and rode his bicycle to the school.
Ye Qingchen has been applying to the driving school for some time. Usually, he goes to school on weekends. When he is in line to take some subjects, he will take a leave of absence. Occasionally at night, Lu Zhou would also take her to practice in some sections of the university town with few people.
No, this little girl drove the car directly to the flower bed on the roadside the night before. Seeing her steering wheel, she still had a close contact with the big tree by the roadside. But tm scared Lu Zhou. Fortunately, the speed of the car was not fast, the airbag was popped out, and nothing happened.
What scares you is not the crash, but Ye Qingchen's scream.
Hey, Lu Zhou thought, I'm afraid she will have to practice driving for a long time. It doesn't mean that she can't drive if she practices. It's okay if there is no sudden situation. If there is a little movement, people will be cowardly and their courage will be broken, and it will be impossible to open. Seeing that he was driving a car, his body was stretched and straight, his brows were wrinkled, his spirit was tense, and he made it clear that he was not an old driver.
The car was sent for repair yesterday, and Lu Zhou can only go to work today by bicycle.
Ten minutes later, Lu Zhou arrived at the floor where Qixing of the laboratory building was. Just after passing a certain laboratory, the hot wind from the door made Lu Zhou feel a little strange.
Recently, BetaGo's stuff is so performance-hungry? Or did the lab add hardware he doesn't know?
This hot air shows that the hardware is fully loaded, and when the laboratory is cooling the equipment room, after all, the building itself has been built a long time ago. If you really want to change some places for heat dissipation, the school will not be able to pass for a while. .
So, Luzhou, the equipment room of this running equipment, knows that the air conditioner is used for heat dissipation...
A lot of luxury.
After all, there are many special policies given by the school to cooperative projects. Electricity really doesn't cost a lot of money.
Now this equipment room can be "hot" through the crack of the door. It seems that the air conditioner needs to be added. If it doesn't work, it can only be changed. This hot air is there, so the noise is definitely inevitable. Although there are not many people in the laboratory building, it is definitely not suitable for a long time.
Lu Zhou walked into another laboratory, where the researcher mostly stayed, so he walked directly into Lu Ming's office.
Lu Zhou said to Lu Ming, "Is the recent progress of BetaGo okay?"
Lu Ming looked up to see Lu Zhou, put down the materials at hand, and said, "I can't say that there has been any progress. At present, there are several groups doing different tasks, but the most important chess training data is still being collected. It is difficult to find in a short time. What a result."
Lu Zhou was surprised when he heard it, "Then I think the equipment room is running a little full?"
After hearing this, Lu Ming smiled, "Oh, that's because some researchers took some spare equipment to mine Bitcoin. I also read the materials, and there is no major problem, so I will give them a try."
Lu Zhou, "..."
That's an excellent researcher...
"Call in to chat?" Lu Zhou said.
Lu Ming also got up and shouted directly at the door, "Xiao Cong! Come on!"
It didn't take long for someone to enter the office.
Lu Zhou took a look. He knew the person, Cao Wencong, the first group of people who entered the laboratory.
Lu Zhou pointed to the chair beside him and motioned him to sit down.
Lu Zhou then asked, "Your boss said that some equipment in the equipment room is for you to apply for mining. What do you think specifically?"
He was curious about what Cao Wencong said. The other party's impression of Lu Zhou has always been good, and he belongs to the type of people with strong divergent thinking.
Cao Wencong thought for a while, "I didn't know about Bitcoin until a year later. Although the paper was not very well written, after thinking about it, I felt that it could also do something. But I don't know if it's useful or not. already."
Lu Zhou was happy when he heard it, and Cao Wencong's statement was really honest.
He asked, "It's not so good, talk about it."
Cao Wencong nodded slightly and said, "To be honest, Satoshi Nakamoto's article can't be read as a paper. To put it poorly, he just rubbed the ready-made things into a system and wrote an explanation. The key explanation is also written. not so good.
Of course, it is not true that he has no innovation, but I think the crux of the problem is that he introduced game theory into the original Byzantine fault tolerance, which is reflected in its incentive and punishment mechanism.
But this is the creator's intent that I only realized when I used and understood it. Satoshi Nakamoto did not explicitly mention this part in the white paper, nor did he make a complete theoretical proof for it. "
Hearing this, Lu Zhou looked at Lu Ming, "What do you think?"
Lu Ming thought for a while, "After a short look, I almost agree. It seems to me to be very unexpected. The theory can be made up, if Xiao Cong wants to do it. But I think the controversy is certain. After all, a Mysterious people outside the academic circle have improved Byzantine fault tolerance, and it is difficult to convince others."
Lu Zhou nodded slightly. He has paid attention to Bitcoin for a long time, and the true origin is the distributed consensus and Byzantine system that he discussed with Cheng Xuyuan when he was still in school.
Usually, when discussing with Cheng Xuyuan and others, most of them have already put the Bitcoin issue and the Byzantine issue together.
But they are companies, they don't write papers, they don't make influence.
Leslie Lamport, the proponent of the Byzantine problem and the paxos algorithm, a big coffee in distributed systems. Barbara Liskov, proposed a PBFT that satisfies Byzantine fault tolerance in a small-scale distributed network. Several theories have been written down, and this is all a matter of the last century. The former will be awarded the Turing Award next year, while the latter was already a Turing Award winner in 2008.
And when it comes to WeChat, part of the memory cloud system is converted from Leslie Lamport's paxos algorithm protocol.
But you said that a mysterious person put out something, and the problem solved is to create a Byzantine fault-tolerant algorithm in a large-scale distributed network? Results comparable to what two Turing Award winners did?
Well, no one can believe it. Just by listening to Cao Wencong's tone, you can get a general idea.
In fact, Lu Zhou also knew the subsequent development trajectory. When the academic circle reached 1415, some papers began to discuss Bitcoin and put it together with Byzantine fault tolerance. Although the controversy has not stopped, it is said that blockchain is an important field , that probably no one will jump feet. Some schools have also opened blockchain courses after this, most of which are related to cryptography and distributed systems.
Lu Zhou continued, "Okay. You can try it."
And he also asked curiously, "What's the situation in mining?"
This is all digging, isn't it right to be concerned about it? Although Lu Zhou didn't expect to use Qixing's equipment to dig out the reason.
Cao Wencong replied, "It's like this, the boss bought another batch of cards before. At that time, I thought that if I could combine all the cards, I could save other hardware costs. After looking for some information, I found that all this was done was to mine bits. Coin miners, so some multi-card devices are set up in the middle. If you run AI, the computing efficiency is also good, but you need to make some adjustments to the driver, which is also quite troublesome.
Then, mining words. The computing power of the entire network is now about 11T. In the experiment, the earliest card was GTX580. Later, some AMD cards were added. The entire group has a computing power of about 0.1T.
According to a block of 10 minutes, there are about 144 blocks a day, and each block is rewarded with 50 bitcoins. About 144 blocks*50btc* (0.1T/11T) can be mined in one day, 65 bitcoins.
It took 4 days to dig, and there are 250. At $5 now, that's about eight thousand dollars..."
When Lu Zhou listened to his calculations, he was amused for a while. The equipment in the laboratory is worth millions of dollars. Although Cao Wencong used idle equipment, digging one or two thousand yuan a day~www.novelbuddy.com~ can only be used as a game. For Qixing, Luzhou does not seek to make money. He does research on equipment and produces any results, and the value obtained is far greater than the value of the bitcoins mined here.
After all, laboratory equipment is not used for mining. If it is a real bitcoin miner, the choice of equipment will be considered based on cost performance, and then consider what the current cycle is. And it won't be long before the graphics card and the like can't mine Bitcoin right away. It's cheap, it doesn't make much sense.
Cao Wencong continued, "I will archive things. But mining Bitcoin should be stopped immediately, and there is no point in mining. Maybe I will try running a private chain next, which does not require such high performance."
After listening to it, Lu Zhou understood a general idea. He said to Lu Ming, "Blockchain is up to you to decide whether to initiate a project or not. At present, funds and personnel are limited, and we mainly focus on promoting AI research."
Lu Ming nodded, "Well. You can rest assured, I will grasp it. Xiao Cong also has some research significance. I will consider contacting the school to do distributed projects, which can also save some manpower."
After hearing this, Lu Zhou nodded slightly, and then talked with Lu Ming about AI and BetaGo.
That's what he came for. Cao Wencong, this can only be regarded as an interesting story and an episode.
