The top student must be diligent.

Chapter 118: Tens of Millions of Attacks, Zero Leaks
"Well... okay, let me think about it."

Xiao Yi did not refuse in the end. After all, he was not a pedantic person.

Anyway, this money is nothing compared to the $1000 million commission they will get after completing the project.

But, this is the first time I have so much money to spend, and I really don’t know what to buy.
How to spend $15?
Waiting online, urgent.

Calculating the exchange rate, it seems that 6.5 RMB equals 1 USD, which is equivalent to...

I'll do it!

Nearly 1!

How many fully-loaded Eyes of the Prodigal can this amount of money buy?
Although the price of graphics cards has skyrocketed due to the rise of mining, 100 million is still a bit too much.

But obviously, he couldn't spend the money on something like maxing out the Eye of Prodigal Son.

So what should I buy?

After a long thought.

Suddenly his eyes lit up and he asked, "I want to buy a server, is that ok?"

"Of course that's totally fine! And it makes perfect sense."

Kleinrock smiled and said, "When the time comes, just write it down on the funding purpose. It won't be a problem to run a dedicated server to simulate our protocol."

"But what kind of server do you plan to buy? Depending on the purpose, the configuration will also need to be changed. Of course, I have connections and can buy the best configuration at the most favorable price."

Xiao Yi said: "I plan to try to see if I can create a blockchain when the time comes."

“Build a blockchain?”

After hearing Xiao Yi's words, the three people present showed surprised expressions.

"That's a bit surprising." Kleinrock said, "To build a blockchain, you do need a small server, but the construction process is also quite troublesome and requires a lot of computer expertise. Can you do it alone?"

"Hmm... it should be doable." Xiao Yi said, "I've also studied it over the past two days. Although it looks a bit troublesome, it's not a big problem."

He thought about this idea that day. Anyway, the concept of blockchain is very popular now and the country is also vigorously developing blockchain technology, so he just followed the country's call.

Of course, he also wanted to put his mathematical ability into practice and see if he could use his abilities in applied mathematics.

He has no prejudice against applied mathematics.

But after hearing his words, the three professors couldn't help but look at him deeply.
You are a student who has never studied computer science, but now you are saying that it is not a big problem to build a blockchain?
They couldn't help but become curious about what kind of blockchain this kid would be able to create.

"I think with your mathematical ability, it might be even more amazing if you could develop a mining algorithm," said Terence Tao.

"This is also under consideration." Xiao Yi said with a smile.

"Have you really considered it?" Tao Zhexuan raised his eyebrows. "If you really come up with it, I will help you promote it."

"Then thank you in advance." Xiao Yi said.

"Okay, I'll contact someone later and build a server for you."

Professor Krainrock said.

But at this time, Xiao Yi thought of another problem. He will return to China next month. How will he bring back the server he bought here?

"Well... this is indeed a problem."

Kleinlock thought for a moment, then clapped his hands and said, "How about this? You give me a delivery address in China, and then we'll ship it directly to China."

"Won't this cause any problems?" Xiao Yi asked.

"No problem. Although I applied in the United States, the funds can be used to purchase things from any country." Kleinrock is old and has experienced all kinds of things. "If this project is a government project, it may be a little troublesome, but since it is from the World Bank, there is no problem at all. Don't worry."

After hearing Kleinlock say this, Xiao Yi felt relieved.

"Thank you, Professor."

"It's okay, no need to thank me, you deserve it."

Kleinlock waved his hand and said nonchalantly.

"So, is this the end of our meeting today? Get the program done as soon as possible, as we have to attend the Joint Mathematics Conference at the end of the month."

"OK, that's it!"

Several people agreed.

But at this moment, the office door was suddenly knocked again.

"Come in," said Terence Tao.

They turned to look at the door, and then saw a man walk in.

"Huh? Professor Douglas, why are you here?"

After seeing this person, Terence Tao was surprised and asked, "Shouldn't you be in San Jose now? The Joint Mathematics Meeting will be held soon, right?" "Haha, Tao, long time no see. I just rushed here from San Jose."

The uninvited guest said with a smile, then he turned his gaze to Xiao Yi and laughed heartily: "This should be the famous young genius, Xiao Yi, right?"

"Nice to meet you."

As he said that, he walked forward, extended his hand to Xiao Yi and shook hands with him.

Tao also began to introduce: "This is Professor Adam Dougs, the current director of AMS. Of course, Professor Dougs is also a member of the organizing committee of this year's Joint Mathematics Meetings."

"Hello, Professor Douglas." Xiao Yi nodded.

"I'll keep it short because I have to go back to San Jose for a meeting soon." Dougs said, "I came here specifically for the paper that Mr. Xiao recently published."

He said to Xiao Yi: "The Xiao polynomial expansion you proposed in this paper has now spread throughout our mathematics community, so we also hope to invite you to the conference to share your thoughts on this new expansion method with everyone."

"This..." Xiao Yi was stunned: "Isn't the Joint Mathematics Conference about to start? Can you still arrange a time for me to give a speech?"

Dougs smiled and said, "They can set aside a day for you at Princeton, so we can certainly set aside time for a speech for you."

"Speaking of which, we actually wanted to invite you to give a talk on the twin prime conjecture at our joint mathematics conference, but who would have thought that Princeton would make the announcement first, so we had to give up."

"But the current Xiao polynomial expansion has shown very powerful effects just a few days after its birth, so we also hope to use your speech to bring a surprise to all the participants of the Joint Mathematical Conference."

"I just don't know if you are willing, Mr. Xiao."

"I……"

Xiao Yi was helpless, but finally thought, okay, since I'm already here, this one time won't make a difference.

Then he nodded in agreement, but still said, "Of course I can only talk a little bit. After all, I haven't prepared anything yet, so I can't talk for long."

"Haha, it's great that you can agree." Hearing Xiao Yi's agreement, Dougs smiled and said, "A single report is only 45 minutes, so it doesn't need to be too long. You can just talk for 30 minutes and use the rest of the time for communication. Maybe the participants will be even happier."

Xiao Yi nodded: "Okay, that's it."

"Okay, then we'll be waiting to welcome you in San Jose in a week." Dougs nodded, then looked at the time and said, "It's time for me to go too. Goodbye everyone!"

So the director who had just arrived for a few minutes left immediately.

"It seems he is really busy."

Kleinrock said.

The other three nodded.

……

Time passed quickly.

About four days later, their cross-chain transaction protocol program was officially completed, and after a simple simulation, its security was fully proven.

During the simulation, they ran a "transaction account" on two computers respectively, and the transaction process took place on a server in the UCLA computer laboratory. This server served as the "third-party transaction platform" in this cross-chain transaction process.

The end result was a great success.

When the computers representing the buyer and seller start running the trading program, no matter what methods they use, they cannot intercept the transaction information of both parties.

As the "server provider", they are also unable to intercept the funds of the two accounts based on their server data.

And in the process of simulating hacker attacks, it will be even less effective.

"Hahaha! What a perfect deal!"

When the final result came out, Kleinlock laughed.

Some people from UCLA's Computer Science Department also participated in the experiment. When they saw the final result, they were all surprised.

Tens of millions of attacks, zero data breaches.

The security of this protocol was beyond their imagination.

Their laboratory has been researching the topics of blockchain and multi-party secure computing. They have also simulated the security of current cross-chain transaction protocols. However, facing the most advanced hacker attacks, it is impossible to guarantee 100% security.

And now...

For a moment, they all looked at the Chinese boy standing next to them.

According to their Professor Kleinlock, the reason why this protocol is so secure is largely due to the mathematical help provided by Xiao Yi.

Thinking of this, they couldn’t help but wonder, if one is good at math, can one really do whatever he wants on the computer?
"Okay, let's call it a day!"

As the last simulation was completed, Kleinrock clapped his hands and said, "Pack up the program and the paper and prepare to send it to the World Bank!"
