Yu Haijun looked at the theory of the financial system with fascination, there is such an exquisite security system in the world, everything is open, but there is no flaw.

On the basis of this super system, the Central Bank of the Empire is responsible for checking whether the major financial institutions are legally compliant with the access to this system, such as: whether the issued client has been maliciously modified, phishing law enforcement, and deliberately testing the block chain of an institution to see if they are delayed or disguised transactions.

Relying on this distributed storage and encryption system, each institution can issue its own currency, use its own assets, stocks, and bonds to mortgage to the hashrate mining machine, and can issue the corresponding amount of currency.

There are bancassurance companies and reinsurance companies in the market, and eventually reinsurance companies will be subject to the supervision of the central bank, review the safety of their assets, provide ultimate insurance, and prevent excessive speculation or lack of liquidity through the fluctuation of insurance amounts and interbank interest rates.

Similar to the principle of computing power provided by mining machines, all institutions involved in the issuance of currency will also obtain certain benefits due to the overall inflation of the currency (seigniorage), so all institutions with certain assets are keen to participate in the issuance of currency, which has become an investment means of asset preservation.

Banking insurance companies assume the role of market makers, ensuring that each currency has a market price and can be circulated at any time, as long as it is an insured currency, it is basically equivalent to hard currency.

In the information, Yu Haijun also saw the attributes of the Fujiko monster Niang by the window that he had just come into contact with, and it was actually related to the distributed storage system.

Similarly, all users who "hire" Fujiko Monster Niang by the window have their identity information encrypted and stored in a distributed manner on all clients, using super encryption and decryption computing power similar to the currency issuance network to ensure information security. It can be said that the principle of the currency issuance network has profoundly influenced the entire Internet.

Whether it is a taxi monster girl, a wristband monster girl or a computer monster girl, it uses another encryption and decryption computing power integration built by a general-purpose CPU, which is called the monster girl computing power network.

Understand the working principle of the monster girl,And then through the official software integrity detection tool,You can ensure the security of privacy,That is to say,Now the rattan system by the window used by Yu Haijun is actually quite safe.,I didn't expect this.,He thought the boss of this black Internet café would play something boring.。

Unconsciously, the time came to 9:30, and Hatoha Zi came to the side of the Yuanzhou rat and said, "It's almost 10 o'clock, we should go back to the dormitory." ”

At this time, the Yuanzhou rats realized that they actually forgot to ask the boss, "Where can I get a credit card?" ”

The government knows that children have no self-control, so they do not allow children in nursery schools to apply for credit cards, but banks have a way.

Big banks don't dare to do it, private banks do. Similar to Mi Longjun opening a clinic alone, there is also a person in the bank who does it.

The owner of Dr. Bang Billiards introduced them to a private bank called RAND Bank, with only one employee: the boss himself, whose name was RAND.

Rand's business is to reach a gentleman's agreement with the children in the fairy circle nursery, although it has no legal effect, but because most of the children have a stable high income after graduation, there is basically no problem with the payment.

Even with half an hour left, Lan Dejun quickly rushed to Dr. Bang Bang, with a smile on his face, and he was angry: "Wow, can you three apply for a card together?" Thank you so much, I know '**************' as soon as I look at the faces of the three of them, don't worry, I'll do it for you right away." Fill out the form and it'll be OK in 10 minutes! ”

Next, Lan Dejun began to talk about the rules of applying for cards, it turned out that the amount of their newborn babies was relatively small, because they didn't know their temperament. The most important thing is to see if they have good academic performance and good attendance.

He also has a crooked way to generate income - cooperating with nearby merchants, and the credit cards he issues will be discounted at the cooperative merchants to make money from the merchants, and he proudly said: "One-third of the merchants near the nursery have the L mark of our Rand Bank, which means that you can use my credit card with them." If you want to shop online, you can come to Dr. Bang Bang, here can help you pick up your package. ”

The big guys are all nodding their heads while filling out the form, however, Chi Qingci and Yuanzhou Rat glanced at each other, and they both saw the thoughts in each other's eyes, if they had money and bought their own computers, who would come here to surf the Internet? I doubt that Dr. Bang's model can be sustained, but the business model of RAND Bank is good.

Later, they learned that children in the nursery school were not allowed to apply for Internet access, which was really sad.

Nani? Only 1000 yuan? And the interest rate is as high as 17%, and if they don't pay it back next month, they will have to pay such a high interest, and the three children expressed their disappointment, and it is obviously impossible for them to ask for a large villa. Newborn babies really have no human rights.

Do the math, the nursery lives for three years, 12,000 a year, a total of 36,000, and 17% interest per year, which is really not cheap.

Gu Yu Zi looked at his two little friends, and he had some hesitation, and Qi Qingci and Yuanzhou Mouse both decisively submitted the form and filled in all their information truthfully, they were confident boys, thinking that 36,000 minutes could be repaid with interest.

Hatoha Purple had no choice but to follow the crowd and complete the formalities.

Yuanzhou Rat didn't know how this lender could recover this illegal loan to the children in the nursery, maybe according to the intelligence network, he found the unit where the children worked at that time, and held up a banner that read, "There is a debtor and a master, Lao Wang owes me 35,000!" "Something like that.

Rand said it would take a few days to investigate their true information, and within a week they would start having credit for 1,000 golden eggs a month.

"Bye-bye!" After completing the formalities, Rand left, and at this time, the three friends saw clearly that Rand was wearing a vest, and the back was written "Stay away from illegal fundraising, build a harmonious fairy town together" and "Everyone is responsible for preventing illegal fundraising".

Chi Qingci and Yuanzhou rats glanced at each other and laughed at them.

They seriously suspected that the RAND Bank was secretly engaged in illegal fund-raising, otherwise where would he get so much money from a bare-bones private bank?

The eyes of the Yuanzhou rat turned around, and Chi Qingci found it and said, "What are you thinking?" ”

Yuanzhou Rat: "I hope to be able to make money to pay off consumer loans soon, you say, if we solve the problem of children in the nursery using their own computers to access the Internet, will we be able to make a lot of money?" ”

Qi Qingci: "If this problem is easy to solve, Dr. Bang Bang's business will be robbed by us, which shows that it is not easy to solve." ”

Yuanzhou Rat: "If it is easy to solve, it will not be our turn." I've decided to continue looking for information in the Internet café, so let's go back first! ”

"No way!" Hatofeather Purple and Chi Qingci screamed at the same time.

Hatoha Zi explained: "The squad leader will give Xia Luosang a small report, if we come out together but don't go back together, we will also be criticized together, you just wait, can't you come back tomorrow night?" ”

Seeing the pleading eyes of the dove feather purple, the Yuanzhou Rat finally sighed and went back with them dejectedly.

The next day, after seeing the Yuanzhou rat, Xia Luosang breathed a sigh of relief: "I thought you were abducted by bad guys, where did you go yesterday afternoon?" ”

Yuanzhou Rat said: "I went to the town government yesterday and saw the robot fighting with the flying armed police, it was so exciting!" ”

"What!" Xia Luosang: "Tell me about the situation at that time!" ”

Under the attention of the keepers and friends, the Yuanzhou rat added fuel and vinegar to tell the story of the incident, of course, the matter of the underground passage is omitted, so as not to delay the good deeds of the robot rebels.

Xia Luosang: "You said that you established a friendship with the self-media anchor Xiao Man?" Yes, she is very popular on the Internet now, because she is suing Hatsune TV for compensation of 10 million golden eggs. ”

Far Continent Rat: "Really? It's really coming out soon, and yesterday she told me that she wanted 1 million, which may be a strategy to repay the money on the spot at a sky-high price. ”

Gu Yuzi admired: "You still dare to stop the flying armed police?" How brave! ”

Yuanzhou Rat said awe-inspiringly: "I can't let them kill innocents indiscriminately, robots are also people, in fact, I am going to go to the town government to take a walk to support the liberation movement of robots." ”

Xia Luosang chuckled: "Your idea is so advanced, this morning's news report, our mayor sympathizes with the cyborg thugs, but after all, thugs are thugs, and they will be punished." ”

Yuanzhou Rat smiled ambiguously, the mayor of the town was forced to be helpless, it seems that the plan of the mechanical rebels is going well, the mayor has been secretly controlled, who let him have the handle to be held?

Because learning in the nursery is all about playing, everyone is very relaxed, and the Yuanzhou rat asks Xia Luosang, "Why are our nursery students not allowed to use the Internet by themselves?" In fact, we can learn a lot of things by going online, yesterday ...... Ahem, I went outside to check the information of the financial system, and the information on the Internet may be clearer than what Xia Luosang said. ”

Xia Luosang: "You secretly went to the Internet, I have long heard that there is a black Internet café near the nursery." Don't go next time, it's illegal, if I find out again, you may not be allowed to go out of school, you have to think about the consequences. ”

Hearing such a terrible excommunication, the Yuanzhou Rat was dumbfounded, and glanced at Hatofeather Purple and Chi Qingci.

Think about these mechanical security guards who won't let him in after 10 o'clock, what can't they do? If you are trapped in a nursery school, isn't it like going to jail?

Yuanzhou Rat said angrily: "We already have knowledge close to that of adults, why do we have to control it so strictly? I could drop out of school! ”

Xia Luosang said solemnly: "Your knowledge is okay, but you lack the habit of integrating into the collective, the most important task of the nursery school in the past three years of study is to train you to become a part of the collective life, telling you that if you do not integrate into the collective, do not obey the social division of labor, you will be as poor as those small vendors in the back street, and earn 1000 or 2000 golden eggs every month."

And if you obey the arrangement of the system, you can get 8,000 golden eggs for any job, as well as various benefits, stable income, and respect. ”
