Liu Cheng actually likes the fact that he is a good teacher. He also wants to explain the key to not breaking the law. However, Liu Yinuo is unwilling to listen at all.

An anonymous chat software is very easy to develop. The simpler the function and the more exquisite the core functions, the more simple the development difficulty is.

For example, when Liu Cheng was still in Tongji, his graduation design was an article titled "System and Software Design Protection of Slaughterhouse Automation Assembly Line".

He stayed up all night for more than two months and finally completed his own graduation project. He also obtained contact from a domestic slaughterhouse to provide security upgrades for their systems and software.

Their automated assembly line was hacked and the other party asked for two million R. In order to resume production, they had no choice but to pay, but soon the slaughterhouse was asked for a second time.

Again and again, not over and over again.

Liu Cheng tried his best and completed the security upgrade of the other party's automation assembly line system and software.

The other party paid 200,000 yuan for this and gave Liu Cheng a full-cow banquet.

It was also at that time that Liu Cheng realized that the taste of Luxi yellow beef is worse than that of Wagyu beef, but it lacks commercial packaging and sells the price far less than that of Wagyu beef.

He only upgraded the other party's safety system. During the contact process, he realized how complicated the slaughterhouse assembly line operation is and the degree of automation is very high.

Why hire him a newly graduated college student?

Because their system introduces foreign industrial software, it is difficult to communicate with foreign countries, the other party responds slowly, etc.

Domestic network security is in a stage of wild growth, and no one pays attention to this matter or does it, so he can only come to him.

The more complex a software is, the more bugs it has. The software called Joker written by Liu Cheng was quickly completed because of its few functions and sent it to the laboratory for identification.

At least the National Computer Center laboratory, two security companies that can view Windows system codes, did not find the back door of this Joker.

It took only half a month before the joker went online quietly.

Liu Cheng doesn't need to worry about promotion, but he is still very concerned about how this intrigue software will be promoted.

"This hook is too straight!"

Liu Cheng frowned and looked at the joker who appeared on the dark web, his head hurt.

Posts selling anonymous chat software at high prices have appeared on the dark websites such as Silk Road, Alpha Bay, Tor, and Farmers Market.

This kind of straight hook fishing is only a deceiving person! It is not free, not open source, and has simple functions. It is useless except for anonymity. How could anyone buy it?

The price is US$300! In the same way, it is as high as about 2,000R!

Anyway, Liu Cheng was only afraid of this price.

The dark web, actually should be called a deep network, is a technical application based on hidden routing information.

When users access the Internet, they do not need to disclose their identities to any passing network server or route, and are completely anonymous.

The earliest dark web should be called the Tor system, which is onion routing.

This is an open source project, and Tor is not a profit organization. In the wilderness of the dark web from 2003 to 2007, 80% of Tor's development funds came from the American government.

Political asylum has led to the technology's monsters, and the underground world is becoming increasingly large, more complex, and more and more vicious events.

The FBI and CIA finally let go of their disputes and sat together, joining forces with the ATF (USA) and the NSA (National Cybersecurity Administration), spending tens of millions of dollars to finally explode the technical monster Tor they cultivated.

I thought the matter of blasting Tor would be over, but the development of the matter exceeded their control.

Because of the maturity of technology, after Tor was blasted, dark web users lost their largest gathering place.

But more gathering places have been established...

The dark webs such as Silk Road, Alpha Bay, Tor, and Farmers Market appear in the underground network like mushrooms after a rain. They are more hidden, safer, and more segmented.

It can be said that to some extent, the "decentralization" advocated by some groups has been completed.

The American government had to launch the Tor project again, hoping to include dark web users in supervision again.

If you lose control, you will lose control. After you open Pandora's box, you still want to close it?

Liu Cheng was quite helpless, and his work within the system was somewhat rigid.

In his opinion, this method of fishing with straight hooks is simply a waste of his labor. Can he catch fish?

It was indeed not as Liu Cheng expected.

The dark web is filled with various anonymous chat software, most of which are free to use, Telegram, Wire, Hack.Chat, etc. These software are even open source.

The Joker intentionally posted in the system was too cold to post! He didn't introduce anything and was expensive, which immediately attracted a lot of criticisms and even scoldings to his relatives.

Even Liu Cheng couldn't stand it anymore and even wanted to come out to refute it in person.

However, considering that he was not responsible for promotion within the agreement, he was too lazy to make trouble. Just as Liu Cheng was about to close the page, clean the logs, and exit the dark web, Liu Cheng received the first order.

Then there is the second and third...

The purchase volume on the first day exceeded Liu Cheng's expectations for Joker, and the download volume exceeded 3,000...

this…

Liu Cheng kept blinking and watching the rising download volume, the US dollar was soft...

Straight hook fishing really caught fish, and it is growing rapidly at a speed that is consistent with the popular Internet application fission. When I woke up the next morning, the purchase volume exceeded 20,000.

It was during this day that Liu Cheng received more than six million US dollars.

And all this money belongs to Kuway Information.

Liu Cheng had no idea what was happening because he had no right to view the data of these users, and he had no idea why this phenomenon occurred.

The criticism here has been overturned, while the download volume and user scale have increased fissionally.

Soon, Liu Cheng received a call from Director Peng. Director Peng did not discuss the issue of the six million dollars, but told him to get a special industry license.

Liu Cheng was completely confused, and Kuway Information entered the monthly revenue club with this simple and easy-to-use joker.

This is so magical...

"Director Peng, this six million knives is so hot." Liu Cheng came to the Internet Information Office for the first time, and he meant to hand over it.

He has already obtained the development cost of this software. The money he shouldn't have received by himself is the best and safest not to touch it.

"If you want a horse to run, but you want a horse to not eat grass, there is no such reason in the world. If you keep it safe, pay taxes, it has nothing to do with us."

"Besides, you are also taking risks. You must be more careful in technology to ensure that you are not exposed. Do you understand?" Director Peng put down his enamel teapot and smiled.

Originally, with the mentality of having no dates but having no dates, this matter was so simple and successful, which was beyond Director Peng's expectations.

"I know." Liu Cheng has absolute confidence in protecting his own safety. These users are engaged in black and gray industries, with extremely cruel methods. He would rather not continue to operate the Joker than expose himself.

"User needs are the primary productivity, everything is based on user needs, and we should maintain it well." Director Peng once again emphasized the importance of user needs.

"I understand." Liu Cheng took the special industry license and returned to his nest and put the license in the safe.

What he couldn't understand the most now was why Jokers sold so expensively but so crazy?

However, he suddenly thought of the previous marketing of Weuniu and felt a little relieved.
Chapter completed!
