"I didn't expect the computational force curve to change so much in such a short period of time, it seems that I missed a good show. Pen ~ Fun ~ Pavilion www.biquge.info"

Lin Hong opened the control end of the super worm to himself, and began to enter filter conditions in a targeted manner, collect information in a targeted manner, and find answers.

The computing power of the main network has increased several times in a very short period of time, which is an extremely abnormal signal, and Lin Hong must find out the cause of this situation, and then make targeted improvements.

Although Bitcoin's computing power access network is completely anonymous, there are no 100% secrets on the network, and unless you are not connected to the Internet, there will always be various ways for people to find clues.

Especially a super master like Lin Hong.

……

More than twenty minutes ago.

California Institute of Technology, USA.

It was late at night, but the lights were still on in the computer room of the computer department of the California Institute of Technology, and in the huge computer room, hundreds of computers had been turned on, but the entire computer room was empty and there was no figure in sight.

At this moment, a young white man with long brown hair suddenly emerged from under a table, and he looked back at the door, as if he was afraid that someone would come in.

His name is Varen and he is a junior in the computer science department at the University of California.

In the evening, few people will come to the computer room to get on the plane, and today is the day of the school holiday, and almost no one comes.

Valen had been preparing for today's action for several days, specifically hacking into the schedule of the school's computer room, knowing that no professors would be teaching here today, and he had also deliberately established a good relationship with the administrator of the computer room, so that he could let go here.

Valen usually looks big and mediocre, but everyone doesn't know that this is just a façade, in fact, he is one of the members of the number one hacker group in the United States, "Mask Island", although only a peripheral member. But this is already very remarkable, you know, "Mask Island" usually does not easily attract members to join, must be jointly recommended by two official members to obtain the membership qualification, after obtaining the qualification, must also pass some tests to be recognized by the relevant people, and finally become a peripheral member.

Valen has been very interested in computers since he was a child, and at the age of eight he aspired to be a great computer engineer. Although his ambition has changed slightly as he has grown older, it is not much different, which is why he was admitted to the computer science department of California Polytechnic University.

What appeared on the monitor in front of Valen was a graph, which was exactly the same as the graph of the computing power of the entire Bitcoin network that Lin Hong saw.

“37mhash……”

Valen muttered, then shook his head with some pity. Today, his experiments are not complete.

He came to the school computer room so late in order to test his idea of a 51% attack on the Bitcoin network.

As a hacker, he learned about this magical virtual currency from a friend shortly after the birth of Bitcoin. And after reading the Bitcoin "Creation Bible", he immediately became a loyal supporter of this currency.

Bitcoin was so perfectly designed and so elegant, that Valen was shocked and fascinated at the same time. Yes. In the eyes of him and a few hacker friends, Bitcoin is more glamorous than those beauties.

"Perfect" is the most used adjective by Bitcoin supporters, the designers of Bitcoin, almost all the disadvantages of the previous virtual currency have been taken into account, absolute anonymity, security, no dependence on the central bank, trust ...... All of these features are perfectly and organically combined and elegantly realized.

Before this, no one could have imagined that such an anti-heaven thing would appear, which was beyond everyone's imagination.

She was so flawless that she could barely find a single blemish. Even the "deflationary" character, which has been criticized by many people, has a small difference in the proportion of supporters and opponents, and no one can know for sure whether "deflation" is good or not, and everything can only wait for the test of time.

However. Is Bitcoin really that perfect?

Valen doesn't think so now, and after a period of intensive research on Bitcoin, he finally made a major discovery.

This is indeed a great and exciting discovery, at least in his own opinion, since no one has yet made it. Valen believes that his discovery could shock hackers around the world.

He did not publish this finding directly on the forum, but chose to prove it to everyone with practical actions, which will be even more impressive.

In this way, people all over the world will know that in the history of Bitcoin, there was once a person who successfully controlled the Bitcoin network, and he was the "Bluebeard" of the "Mask Island".

Thinking about this matter, I feel that the cells in my whole body are going to cheer and jump, and my whole body is trembling slightly.

Valen kept the secret tightly as he immediately embarked on his own plan to "capture the net". If he can find this "loophole", others will definitely find it too, especially the mysterious designer of Bitcoin, no one knows Bitcoin better than himself, and when the other party reacts, maybe he can plug this loophole, and he has to achieve his goal before everything changes.

Now Bitcoin is simply worthless, and Valen's "capture of the net" is not to get more Bitcoin, but to make a name for himself in the industry, so that hackers all over the world know him and prove his strength to them.

After a few days of hard work, he finally got the administrator of the computer room, found a time when no one was on the computer, and he came to the school's computer room.

There are a total of 120 computers in the school computer room, of which 80 are the latest machines, the configuration is very high, is the mainstream top configuration, the school is of course reluctant to spend so much money to buy such a good configuration of computers, this batch of computers is the school anniversary, an alumni of a famous IT giant company gifted.

The total computing power of the Bitcoin network is still very small, and Wallen believes that only by using these 80 latest computers for mining, he can directly occupy more than half of the computing power and realize his plan to "seize the net".

So, he turned on all 80 machines and installed his own custom mining software one by one.

This mining software is modified on the basis of open source code, as long as he installs this software on the computer, he can contribute the computing power in the computer, and finally gather it on one of the hosts to form a total computing power, and then use this computing power for mining.

This is also a distributed computing solution, but with a relatively small number of machines.

As Wallen continued to install custom mining software, the computing power of the Bitcoin network began to climb gradually.

11 trillion...

12 trillion...

13 trillion...

……

After installing dozens of machines, Valen returned to the main machine to take a look, and found that the angle of the computing power curve was close to 75 degrees, and he was greatly encouraged and motivated to continue installing the software.

15 trillion...

16 trillion...

……

Wallen's mood is getting more and more excited, and the smile on his face is getting bigger, and he is waiting for the exciting moment to come, once his computing power exceeds the computing power of everyone else combined, his plan to "capture the net" will be successful, and at that time, he can publish a post on the open source community to announce that he has taken over the Bitcoin network.

He had even thought about the content of the post, and he would knock his ID - Bluebeard - at the end of the post.

Eighty machines were finally installed with mining software, and although Valen was a little tired, he was very excited, and he couldn't wait to walk quickly to the host computer to check the current computing power of the main network.

However, when he saw the graph, he was stunned.

Things didn't go as smoothly as he had imagined.

He saw that when the total computing power reached 18 trillion, the speed of climbing suddenly made a new breakthrough, almost without any stop, and jumped directly to 20 trillion, then 22 trillion, 25 trillion......

Valen was stunned and looked at the graph of the computational force that was almost straight up, and muttered:

"This ...... What the hell is going on? I don't have that much computing power ......"

Eventually, Valen realized that there must have been someone else connected to the network at this time, and it was providing a very large amount of computing power. I just don't know if it's the natural increase in computing power, or if someone like him wants to win the net to contribute.

"**......" Valen scolded weakly.

He was so angry that he almost vomited blood, seeing that his plan to "capture the net" was almost successful, but he didn't want this to happen at the last minute.

Those bastards, who didn't access early or late, just wanted to access at this time, which almost made his plan fall short.

"Fortunately, there are still 40 computers, and I hope that these 40 computers can contribute 51% of the computing power!"

With this in mind, Valen began a new round of software installation.

Although the remaining forty computers in the computer room have been around for some years, and the CPU computing speed is relatively slow, after all, there are forty computers in total, forming a distributed network, and finally being able to exert a lot of computing power.

Every time Valen installed the software on a few computers, he ran to the main computer to observe for a while, and then went back to install it.

After running like this five or six times, Valen finally didn't run anymore.

He saw that the graph in the display was growing too fast, and now it had climbed to 37 trillion, and it seemed to be growing.

The remaining 40 computers, after all, are products of a long time ago, and the computing power is too low, even if they are all installed with software, the computing power that can be provided in the end cannot make the total computing power more than half of the existing network.

Valen already knew that his plan to capture the net would ultimately end in failure, and he had to choose to give up.
