Becoming the richest man starts with making complaints

Blockchain?

Although Zhang Fei is in charge of science and technology, he cannot cover everything. This is the first time he has heard of this term.

The blockchain in the original world originated from Bitcoin. The computing power currency in this world is not yet popular, so not many people know about it. It is not surprising that Zhang Fei does not know.

Blockchain is nothing more than a time-stamped data recording method. It is a link in the entire set of Bitcoin technologies. To be complete, it is a decentralized distributed system.

The name blockchain is actually one-sided.

But everyone called him that, so Cao Shen could only follow the local customs.

In the original world, the entire "blockchain" technology was still very immature when Cao Shen died, because this technology had an inherently insurmountable obstacle, the "Impossible Triangle."

The Impossible Triangle refers to decentralization, scalability and security. These three requirements cannot be met at the same time, and there must be a choice.

This is actually easy to understand. In decentralization, such as Bitcoin, every transaction record needs to be copied by all nodes and broadcast to the entire network.

If you have N nodes, you have to repeat the work N times. If you use a centralized network, you only need to record it once, and at most two or three information backups are enough.

If you want to be decentralized and secure at the same time, the entire system must be very simple in function and will not have much scalability.

Otherwise, it will inevitably be designed to be large and bloated, with many loopholes, and security will not be achieved.

If you choose high scalability and security, you must design rich interfaces and strictly control them to ensure security, which makes it difficult to achieve decentralization.

In the original world, Bitcoin was highly decentralized and secure, but its performance was poor. The network was often blocked, and users had to pay more transaction fees to allow miners to "package" transaction information first.

Later, EOS was released, claiming to be one million TPS, and its performance was much higher than that of Bitcoin.

However, EOS sacrifices decentralization in order to achieve performance. It does not have all nodes being equal like Bitcoin, but has 21 super nodes.

Therefore, this project has also been questioned by some as being too centralized, neither decentralized enough nor conducive to network security.

There are two reasons why blockchain has extremely high security requirements.

First, it is different from ordinary information networks, which is what we call the Internet.

In addition to information data running on the blockchain, a large amount of asset data is running.

If there is a problem with the security of the Internet, the most likely outcome will be data loss or data leakage.

If there is a problem with the security of the blockchain, it will be a very direct economic loss.

If the Internet is an information network, then the blockchain is an asset network.

It is also because all money runs on the blockchain, so as soon as this industry became popular, hackers and white hats started to work on the blockchain.

Before the rise of blockchain in the past, domestic network security entrepreneurship was actually very difficult. Because the security business is very similar to a hospital. If you are not sick, you will not go to the doctor.

Generally speaking, if there are no official mandatory requirements or have not encountered hacker attacks, ordinary companies will not pay attention to network security. After all, buying security products is a cost and cannot create revenue, and generally nothing will happen.

This matter did not start to improve until the country implemented the mandatory requirements of Level Protection 2.0, and security companies were able to comply with the order.

Of course, top Internet companies still attach great importance to security issues, such as the two Ma dads. Several top white hats in the country have been recruited by these two companies.

And another group of top white hats entered the blockchain to do security audits, changing the previous decline and making a lot of money.

Of course, powerful hackers have also moved to fight on the blockchain, and they have done a lot of tricks, big and small. The plot has ups and downs and is more exciting than the movie.

The second reason why blockchain emphasizes security is to ensure that the data on it cannot be tampered with.

Because non-tamperability is a prerequisite for running smart contracts, it can even be said that all consensus algorithms in the blockchain ensure that data cannot be tampered with.

The so-called smart contract, simply understood, is a contract application that runs on the blockchain based on tamper-proof data, such as automatic buying and selling transactions.

To give a simple example, mobile phone bills are automatically deducted.

If it is a centralized system, the data is easily tampered with. After hackers invade, they can change the user's phone plan to a higher-priced one, and then automatically deduct more money.

Therefore, this automatic deduction system cannot be called a smart contract.

The reason why online lottery has been banned is because it is a centralized system and has been extremely popular. If you use blockchain to do it, the data cannot be tampered with and there is no such risk.

The system gave Cao Shen the cloud computing system. Cao Shen studied it carefully and found that this thing can achieve the ultimate in distributed computing. From this, he figured out a way to solve the impossible triangle problem.

Although Cao Shen's current company, Xishen Technology, is a centralized company, Cao Shen is a supporter of decentralization at heart and is naturally a die-hard fan of distributed systems.

He wanted to use this set of things, but the conditions were not yet mature, at least the computing power of the hardware and the communication network could not keep up, so he could only wait.

But it doesn’t mean that nothing can be done. At least this set of technology and distributed concepts, Cao Shen hopes that more people can master it.

Therefore, Cao Shen plans to take out part of the technology first and cooperate with the country to build an "alliance chain".

The number of nodes in the alliance chain is limited, so it is not really decentralized. However, we have to take it one step at a time. Let everyone feel the benefits of decentralization in a practical way.

When Zhang Fei heard that it was a new technology that could make information traceable and non-tamperable in the future, he felt it was very valuable, and immediately made sure to cooperate with Cao Shen's research.

Of course, blockchain also has three characteristics: decentralization, openness, and autonomy, which Cao Shen did not mention.

Since it is an "alliance chain", there must be an "alliance", so Zhang Fei took the lead in teaming up with six ministries and the Academy of Sciences to form a team with Cao Shen.

The specific operation is that each of the seven companies provides a data center to run data.

The entire system was deployed by Cao Shen personally. The seven families are seven nodes that jointly maintain this "data ledger".

Because it is an experimental thing, no one dares to run real business data. However, if it is purely experimental data, the data volume may not be large enough, and the task processing complexity is also very low, making it impossible to test performance and security.

In the end, Mr. Cao patted his chest:

"Run my business data and I'll use some of it for experiments."

Mr. Cao is willing to contribute to national scientific research, and of course other companies readily agree.

Then, Mr. Cao spent another three days educating everyone about blockchain and distributed systems.

Some people are confused after all, cloud computing is still very new these days.

Some people think it sounds like nothing and is quite simple, but after thinking about it later, they feel that it is unfathomable and involves a very wide range of knowledge.

Some simply don't understand the importance of it and simply give up. They just treat it as a task and execute it as directed by Mr. Cao.

In short, no matter what others think. Things were put into place and everything went smoothly.

Zhang Fei was also very happy. This time he was out of the circle, and he was very proud of joining several ministries and scientific research institutes.

So, everyone was happy.

I have been working on the search engine system for a week. The main reason is that the system first needs to use the NLP engine to read and understand the information on the entire network, and then select the corresponding search plan.

There are usually many technical solutions to choose from to solve a problem, which is called technology selection.

A true master of technical architects does the work of selection.

If a person's skills are very solid, we praise him for his good skills.

If a person is very good at selecting, then he is a master of taste.

Although Baidu has introduced new things and good practices in recent years, the technology selection of Baidu Tieba back then was quite interesting. The Tieba page that users see is actually the result rearranged according to the forum format after searching.

With the development of the Internet to this day, the amount of information on the Internet is quite huge. Even with the system's super data processing capabilities, it took a week to clean it up without stopping for 24 hours.

If the system had a face, it should be seen that its face would turn green when dealing with it.

Of course, the system is shameless, but in a room with the air conditioner fully turned on, you can still see steam rising from the top of the system.

[Cao Cao, it’s so hot! 】

"The air conditioner has been turned to the lowest setting, you have an ice pack on your head, there are ice basins around you, and there is an electric fan blowing on you." Cao Shen was wrapped in a quilt and fought with the system.

Although Cao Shen was useless, Cao always felt that he was "fighting side by side." The specific way to cheer up was that Cao Shen kept asking:

"Is the system ready?"

"How much data is missing!"

"Can you come out today?"

[Thief Cao, if you press again, you will die! 】

As the system spoke, another wisp of "fairy energy" came out of its head.

"How about I shave your hair to dissipate the heat? It's so cool to have a bald head, and you don't have to wash it. How convenient!"

【Cao thief! My whole head looks like human hair, so be a human being! 】

"Okay, okay! How about I tie it up for you? It's hot when you put it on me, and it's scary."

[Okay, make it look nice]

"You don't even have a face, so what do you want to look good at?"

So, Cao Shen inserted two Jiujiu sticks on his head, which were not symmetrical in size.

【So ugly! Thief Cao, you are too cruel, did you do it on purpose? 】

"No, no, no, I've tried my best." Cao Shen faced the system with a mirror:

"Actually, they look pretty good. They don't look like the steamed buns we usually eat. The one on the left is a small steamed bun, and the one on the right is a big meat bun!"

[Hey, it seems a bit similar. Look, it’s still smoking, it’s just out of the oven! 】

"Yeah, well, be good and I'll give you three pricks tomorrow, plus a soup dumpling!"

【OK! 】

[It’s time, it’s time for me to take an intermission! 】

"Okay, okay, go ahead."

The system's intermission is to do housework...

I don’t know why, but the system started to get obsessed with housework after cleaning the room for the first time.

When it comes to cleaning and organization, the system is very professional.

After taking over the housework task, she used her "titanium alloy" eyes to scan.

Looking at it, it seems that Cao Shen lives in a bacterial garbage dump!

Cao Shen can tolerate it, but the system cannot!

As a result, Cao Shen experienced the most rigorous cleaning in life.

Every nook and cranny, all kinds of disinfection supplies, all the objects in the house, every part of the system was not spared, and they were all cleaned.

Cao Shen felt that if he hadn't protested seriously, the system could have soaked him in formalin!

After cleaning, Cao Shen felt that even the tabletop was shiny and shiny.

Even under the influence of the system, Cao Shen doubted himself for the first time in his life. Am I dirty?

Seeing all the neatly arranged objects at home, Cao Shen simply wondered if the system had obsessive-compulsive disorder!

And the key is, it’s so neat and tidy, it feels like you can’t start anywhere.

There is no sense of warmth at home anymore!

Cao Shen felt a little at a loss in his own home.

"Where is that piece of paper on the right hand side of my desk?"

[There is a pile of paper scattered on your desk. Which one are you talking about? 】

"The one with the warehouse structure diagram."

[You have a total of twelve warehouse structure diagrams, be specific]

"Marked with red and blue pens, vertical shelves..."

[Sheet 27 of the stack of papers in the drawer on the right side of your desk]

"Where is my white T-shirt with a basketball on the chest?"

[Sliding door on the east side of your closet, with the fifth stacked item on the second layer above]

"Bring it to me."

【OK! 】

Cao Shen breathed a sigh of relief. Fortunately, he still remembered where things were after the system was organized.

What I fear the most is that I have organized my things but forgotten where they went.

Every time the system tidied up Cao Shen's messy home, he felt a happy sense of accomplishment. This sense of accomplishment made the system fall in love with doing housework.

Staring at Cao Shen all day long: You are putting things in random places. If you don’t throw them away, how can I tidy them up?

Oh, by the way, I had takeout for lunch. Go and wash the lunch box. Even if you want to throw it away, throw it out cleanly.

After a while, the clothes washed by the host were dried, and I went to iron them. I just wanted them to be flat and as good as new to feel a sense of accomplishment...

In addition to doing "reading comprehension" these days, the system is busy thinking about what other household chores to do.

In order to prevent the system from being obsessed with housework and not doing serious things properly, Cao Shen even strictly stipulated that only during rest time can he relax by doing housework.

Take two breaks a day, one hour each time...

Finally, one week later, the time came to witness the miracle.

Cao Shen has imagined what a search engine based on a good NLP technology would look like.

Because in the original world, Cao Shen had seen a domestic team with strong NLP technology make something like this.

A very powerful search engine that cannot be used commercially and only serves internal purposes.

Cao Shen knew that there was still a big gap between the NLP technology in the original world and the one produced by the system, but he did not expect that the system's search engine would be so terrifying.

In other words, when machines fully understand human language, the results are astounding.

Cao Shen casually entered the name of an ordinary employee of the company, Li Dagang.

If it is Dudu, it basically searches for the person's name in the whitelist website and returns the results.

You need to judge based on other information about this person which link content points to the "Li Dagang" you are looking for.

If this person has ever appeared online with this name, you can search for some relevant information. If not, then Dudu may not be able to find any information.

Of course, with the development of technology, Dudu also uses NLP technology.

But this is limited to, when you enter "Li Dayue Gong", Dudu will prompt:

Search results for "Li Dagang" have been displayed. Still searching: Li Dayuegong

But the search engine created by the system is different.

The first step is to enter your name.

The second step is to return the search results.

On the surface, this result is similar to that of Dudu, because the entered name may have many duplicate names, and the search engine at this time does not yet know which person you are looking for.

In the third step, the user determines which link is the person you are looking for based on the returned search information and clicks on it.

At this time, the search engine starts to really work. Because through your clicks, the search engine locates which Li Dagang you are looking for.

When you return to the search page again, the entire search content has changed, and all content related to "Li Dagang" is displayed.

And these contents are not directly captured and presented after comparison with the keyword "Li Dagang" on the Internet.

The system reads and understands the information on the entire network, understands the characteristics of "Li Dagang", searches based on these characteristics, and returns the results.

In other words, it is not based on the name "Li Dagang", but on Li Dagang's behavior, his social relationships, his related information, and even the characteristics of his language expression to determine that this person is Li Dagang. The information on this web page was left by Li Dagang. Those who came down may be related to Li Dagang!

No matter whether he used Li Dagang's name, no matter what ID he used, no matter whether he was anonymous or not! No matter whether others mention Li Dagang's name or not!

Relying on NLP technology, the machine understood the content of the entire network, understood Li Dagang, and "picked out" Li Dagang.

So, Cao Shen saw Li Dagang's "life" on the search page, and it was automatically sorted by the search engine, just like Baidu Encyclopedia! Of course, relevant links are also thoughtfully attached.

Li Dagang’s ID number, mobile phone number, family situation, college entrance examination scores, scores in various subjects in college, the names of how many girlfriends he has, what happened with his girlfriends, what social relationships he has, and what others say about him , follow people who have commented and liked on Weibo, what you are interested in, past shopping records, what movies and novels you have read, what sports teams you like, what swear words you have cursed, and even what web pages you have browsed and what your hobbies are...

It also lists a large number of Li Dagang's classmates, colleagues, friends, teachers, etc. in order of the degree of social intimacy.

And there are links that can be clicked. When you click on them, the person's complete information will appear.

No privacy!

Cao Shen tried again. This time he did not enter Li Dagang's name, but entered several characteristics of Li Dagang, including his age, the school he graduated from, and his workplace.

The search engine also located Li Dagang and returned detailed information.

Cao Shen entered "TT Technology" again, and a sorted page also appeared.

It covers everything from products, technology, finance, operations to company news, gossip and more.

Plus all customer information, as well as a complete employee list.

Customer information and employee lists are also "captured" through comparison after understanding the entire network information.

By clicking on the customer information, you can also see the specific business, who are the people on both sides of the connection, and relevant news and gossip about this customer's business.

If you click on a product or technology, you can see all information including official documents.

Although this is not an internal document but a public document, the information is very complete and even includes internal customer training materials!

This is the search I want!

Cao Shen slapped the table, but this thing can't be taken out and used!

Planning to try again, Cao Shen entered the name "Xu Bingqian" in the search box.
