From a university student to a chief academician

Chapter 167 The blockchain system is about to be released globally

Three months later, it's June!

In April, the first phase of the Latitude Blockchain Research Institute of Zhonghu University was completed, and all the equipment was installed in it half a month later.

At the beginning of May, all researchers settled in the Latitude Blockchain Research Institute.

From the beginning of May, Ye Fei spent a week each at Zhonghu University and the University of Electronic Science and Technology of China, and flew back and forth between the two schools every weekend night.

Ye Fei sighed in his heart: "I don't have enough time, I wish I could have a clone, one at UESTC and one at Zhonghu University."

"This way you can take care of both sides."

"It won't be like now, running around on both sides!"

Of course, with such a busy life, the research progress of the two universities is progressing at a gratifying level.

Ye Fei is a manager and only needs to provide research directions for his researchers.

Most of the work is still under the researchers.

By June, through the Gaussian derivative function, five or six kinds of ultra-broadband pulses were found.

However, in terms of performance, there is still a big gap with the world's advanced ultra-wideband pulse, which cannot make the network speed reach 100GHz, and is not suitable for Li-Fi.

The research on the application of asymmetric encryption algorithms is very gratifying. In just two months, half of the research has been completed, and in two more months, all the research can be completed.

At that time, the asymmetric encryption algorithm will be packaged and a blockchain system with asymmetric encryption algorithm as the core will be developed.

This part is very simple and can be completed in a month.

By September, the new blockchain system can be released to the world for trial operation.

University of Electronic Science and Technology, in a laboratory!
Ye Feizheng leaned over his desk and quickly wrote the formula on the paper.

"No, it's still not right!"

Many inspirations collided in Ye Fei's mind, trying to find the best combination of pulses through mathematics.

Ye Feixin said: "Use the Gaussian derivative function to obtain a waveform close to the radiation masking standard in the entire channel."

"The method is correct, but science is like looking for a needle in a haystack. It is very difficult to find the best combination of pulses."

Ye Fei's research method is like this. Some people, led by Ye Fei, calculated a reasonable Gaussian derivative function formula.

Some people, through the pulse machine, input the formula into it to find the pulse.

Another lab!

Yue Hongqing is a researcher doing research with Ye Fei.

When Ye Fei said to fully engage in domestic autonomy, Yue Hongqing was the first to stand up to support Ye Fei, and was also the first to report and do research to Ye Fei.

At this moment, Yue Hongqing's image collapsed, his face was unkempt, his face was pale, and he had thick dark circles under his eyes.

He is sitting in front of the pulse machine, through experiments again and again, hoping to find the best pulse from many bands.

He has been sitting here for three months, eating in front of the pulse machine.

Next to the pulse machine, there is an iron single bed. Yue Hongqing will sleep on the bed when he is sleepy, and continue to study after waking up.

In Yue Hongqing's view, the best pulse can only be found through continuous experimentation.

Therefore, he used the Gaussian derivative function, combined with the pulse machine, and tried to find new ultra-wideband pulses through experiments over and over again.

Yue Hongqing was already very sleepy at the moment, but he still kept his eyes wide open and refused to close them.

After a long time, with a sound of "Peng", Yue Hongqing hit his head on the pulse machine, just as the last number was input into the pulse machine.

He was so sleepy that he couldn't hold on physically at all.

At this time, an abnormal pulse waveform suddenly appeared on the pulse machine, which was instantly captured by the supercomputer in the background.

More than four hours later, Yue Hongqing woke up in a daze.

When he looked up at the pulse machine, he was stunned for a moment, and then his eyes widened in surprise.

"The new UWB pulse?"

He tapped the keyboard excitedly.

Then, he said excitedly: "So that's the case. I said I haven't found it after searching for so long!"

"Sure enough, new ultra-broadband pulses can be found through the Gaussian derivative function. Professor Ye's method is correct."

"It's just that we all entered into a misunderstanding before. We all believed that since the Gaussian derivative function is used, the energy density of the pulse must be affected by the pulse length and pulse integral."

"That's not really the case, it's affected by the pulse width and pulse differential."

"In many cases, it is difficult to meet the radiation masking requirements outside the 5.1-20.3GHz range with only a single pulse. It must be met with a single pulse waveform for radiation masking specified by the FCC."

"I want to tell Professor Ye and everyone else the good news."

After finishing speaking, Yue Hongqing quickly ran out.

Soon, it became noisy outside.

"Professor Ye, someone discovered a new ultra-wideband pulse suitable for Li-Fi."

"What?" Ye Fei, who was doing mathematical calculations, looked up in surprise, looked at the person who spoke, and said, "What you said is true?"

"it is true!"

Ye Fei quickly stood up and said, "Let's go and have a look."

After speaking, Ye Fei walked outside.

After a while, a group of people gathered in front of a pulse machine.

A researcher is sitting in front of the pulse machine, typing on the keyboard quickly.

For a long time, groups of data were displayed on the computer screen.

The researcher turned to look at Ye Fei, and said pleasantly, "Professor Ye, this set of pulses is very good, and it fully meets the requirements of Li-Fi."

"En!" Ye Fei nodded, looked at Yue Hongqing beside him, and said with a smile, "What's your name?"

There are thousands of researchers in the research institute, and Ye Fei has only been here for a few months, so it is impossible for him to know everyone's name.

Yue Hongqing was very excited at the moment, he said excitedly: "Professor Ye, my name is Yue Hongqing."

Ye Fei smiled and said, "Very good, very good, I will report your matter to the higher authorities."

The rest of the people looked at Yue Hongqing with envy. Given the strategic significance of the Li-Fi experimental project in the Xia Kingdom, as long as this matter was reported, Yue Hongqing would definitely be rewarded by the higher authorities.

Many people muttered in their hearts: "Why didn't I have such luck, how did Yue Hongqing find a new ultra-wideband pulse suitable for Li-Fi?"

Academician Ning's office!

Academician Ning looked at Ye Fei who walked in, and laughed loudly: "Professor Ye, congratulations, I didn't expect you to find a new ultra-wideband pulse suitable for Li-Fi."

Ye Fei smiled and said, "Luck, luck, I never thought I would find it."

"I initially tried to use mathematical Gaussian derivatives to find ultra-broadband pulses."

"It is true that the Gaussian derivative function was used to find the ultra-wideband pulse, but a researcher entered the wrong number, and then unexpectedly found a new ultra-wideband pulse suitable for Li-Fi."

"Haha..." Academician Ning laughed loudly: "Science is like this. Sometimes you may not find it if you look for it deliberately, but if you don't look for it deliberately, you will find it instead."

"Yeah!" Ye Fei nodded, "That's right, science is really an interesting thing, full of mystery, which makes people have the desire to explore, and no one knows what will happen in the next second."

"Maybe discover technology that changes the world."

"Yes!" Academician Ning nodded: "This is also the reason why many people like to do research. Doing research can make people addicted, and its happiness is no less than that of reading novels and film and television dramas."

"Yes!" Ye Fei smiled.

Academician Ning said: "Since you have found a new ultra-wideband pulse suitable for Li-Fi, then start the next step of research."

"Yeah!" Ye Fei nodded and said, "Say it!"

Academician Ning said: "The next research is how to popularize Li-Fi. The shortcomings of Li-Fi are very obvious."

"One, there must be light!"

"Second, you can't go through walls!"

"And the light of Li-Fi is visible light, which is also a disadvantage."

"Some people like to turn off the lights and surf the Internet. No visible light can appear at this time."

"Therefore, we have to solve two shortcomings of Li-Fi, one is that there is no visible light, and the other is to allow Li-Fi's wireless network to pass through walls."

"Before we thought about it, it can't be visible light, so there are only infrared and ultraviolet rays."

"But they can't go through walls."

"And what goes through walls are radio waves, microwaves, X-rays and gamma rays."

"Radio waves and microwaves are invisible light."

"It conforms to the characteristics that it is neither visible light nor can pass through walls."

"But their speeds are too low for Li-Fi, only for Wi-Fi."

"Professor Ye, do you have any good ideas?"

Ye Fei frowned and said, "I didn't have a good idea for a while. From all electromagnetic waves, only radio waves and microwaves are the most suitable, but the only thing is that the network speed is too low."

Whether it is visible light or invisible light, they are all electromagnetic waves, but the wavelength is different.

"The network speed is high, but it is visible light, and it cannot pass through walls."

"Those that can pass through walls, two are invisible light, and the network speed is low, and the other two are visible light, but they cannot be used to study network speed."

What can't study internet speed are x-rays and gamma rays.

When X-rays are irradiated on people, they will destroy human white blood cells, cause hair loss, abnormal blood circulation, and tissue necrosis.

Gamma rays, also known as Y-rays, are rays released when nuclear energy level transitions are de-excited. They have strong penetrating power and can kill cells. They are used medically to treat tumors.

It also cannot shine on the body, otherwise it will kill the cells and cause physical damage.

If it is a gamma-ray burst, it is the most terrifying thing in the universe. The energy released in one second far exceeds the sum of the energy released by the sun in a lifetime.

Any planet in the universe, if it is swept away, will disappear in an instant, and there will be no residue left.

Closer to home, from the perspective of all electromagnetic waves at present, only radio waves and microwaves can be used as network transmission.

But they are too slow.

Ye Feidao: "The invisible light and visible light of electromagnetic waves have their own serious shortcomings."

"Yes!" Academician Ning said: "So, we need to find an electromagnetic wave that has a fast network speed, is invisible to light, can pass through walls, and is not harmful to the human body."

Ye Fei nodded and said, "Yes."

Ye Fei and Academician Ning were also at a loss as to whether such electromagnetic waves existed.

Of course, intellectually speaking, this kind of electromagnetic wave must exist, but it has not been discovered yet.

After all, everything is possible with science.

But from an intellectual point of view, maybe they can't discover this kind of electromagnetic wave.

Science has all possibilities, science can also make people addicted, but science can also make people despair.

It's like doing a math problem, and you can't do it no matter how you do it. The sense of despair makes people crazy.

Zhonghu University, Latitude Blockchain Research Institute!
Ye Fei walked into his office and sat down, then called Shi Yao, the chief scientist of the research institute.

Shi Yao is 32 years old this year. He is a PhD in computer and mathematics from Kyoto University. He mainly studies blockchain.

After the institute was completed, Kyoto University recommended Shi Yao.

After Ye Fei personally tested Shi Yao's ability, he made him the chief scientist of the research institute.

After Shi Yao came in and sat down, Ye Fei asked, "How is your research going?"

Shi Yao said with a smile: "In another week, the research on the asymmetric encryption algorithm will be completed. One month later, the blockchain system with the asymmetric encryption algorithm as the core can be created, and then it can be tested globally."

"Yeah!" Ye Fei nodded in satisfaction and said, "There's no big problem here, just keep an eye on it for me, I won't be here for the next month, and I will come when the development conference is held."

Shi Yao asked: "What's wrong? Did you encounter difficulties in your research at UESTC?"

"Hey..." Ye Fei shook his head and sighed: "I have indeed encountered difficulties. This is the first time I have encountered such a difficult research."

Ye Fei's previous research can be solved through mathematics.

But Li-Fi research alone cannot be solved through mathematics.

Because Li-Fi research is not 100% related to science, brain hole is more important.

Shi Yao said with interest: "Can you tell me if it's convenient, I'm a computer student, maybe I can provide you with some help."

Ye Fei said, "Okay, I'll tell you!"

"We are now looking for an electromagnetic wave that has a high network speed, is invisible to light, can pass through walls, and is harmless to the human body."

"Radio waves and microwaves can pass through walls, are invisible light, and are harmless to the human body, but the network speed is too low."

"Infrared rays, visible light and ultraviolet rays have high network speeds and are harmless to the human body, but they cannot pass through walls."

"X-rays and gamma rays can pass through walls, but they are visible light, which is harmful to the human body."

"So, all electromagnetic waves have their drawbacks."

After pondering for a moment, Shi Yao said: "In our computer field, many codes have their own advantages and disadvantages, but we can graft them together, just like plants of different varieties, to bring out the advantages and remove the disadvantages."

"Do you think it is possible to synthesize multiple electromagnetic waves through this method?"

Ye Fei frowned and nodded, "This is a good idea, but I don't know if it will work."

"Electromagnetic waves, after all, are a kind of light that cannot be touched but are ubiquitous in nature."

"It's not a real thing. If you want to synthesize light together, no one should do it!"

"You are wrong." Shi Yao shook his head and said, "Photosynthesis was done more than 20 years ago."

"There is not only photosynthesis, but also photoconversion."

"The Dalian Institute of Physics once converted infrared light into sunlight."

Ye Fei said in surprise: "There is such a thing, but I am ignorant. It seems that I need to consult people in the physics world."

Shi Yao smiled and said, "You usually only pay attention to mathematics and computer research, and you should also look at physics research."

"After all, there is no distinction between mathematics and physics. Many mathematicians study physics and can easily get started."

"If you try to study physics, I believe you can easily get started."

"I will." Ye Fei smiled.

After returning to the University of Electronic Science and Technology of China, Ye Fei approached Academician Ning and said, "Academician Ning, I have found a way to synthesize various electromagnetic waves."

"Photosynthesis?" Academician Ning said, "Yes, we can synthesize electromagnetic waves."

"Since every electromagnetic wave has disadvantages, we can take out the advantages of multiple electromagnetic waves and synthesize a brand new electromagnetic wave."

"Such electromagnetic waves must have a high network speed, are invisible to light, can pass through walls, and are harmless to the human body."

"Yes!" Ye Fei said: "We are not good at this aspect, I suggest consulting physicists, they are good at this aspect."

"Yes!" Academician Ning said: "I know many physicists, I will call them immediately to consult them."

After speaking, Academician Ning took out his mobile phone and typed.

In the next month, Academician Ning called several physicists to ask them about synthesizing light.

Ye Fei also benefited a lot, and at the same time developed a strong interest in physics.

"So physics is so interesting!" Ye Feixin said: "If you have the chance, you must study physics."

Ye Fei discovered that physics is different from mathematics.

Although mathematics is the foundation of physics, physics can produce various technologies.

Almost 90% of the things around modern humans are physically manufactured.

As small as screws, as large as airplanes, and as large as satellites.

Ye Feixin said: "Although it's cool to solve math problems one by one, it's also very cool to create technologies one by one to benefit the world."

At this time, in September, the blockchain system created by the Latitude Blockchain Research Institute of Zhonghu University will be released to the world soon.
