No matter what, Silvio Micali's sudden question still caught Xiao Yi off guard.
After all, no one told him that in addition to pure mathematicians, this report also involved computer scientists.
So what he just talked about is also in the field of pure mathematics.
If I had known that there was a computer scientist here, he would have given a brief talk on the application of cryptography.
Of course, although he was in a daze for a while, he soon thought about Mikali's question.
I have to admit that what the other party proposed is very interesting.
Will Xiao's expansion be directly applied to the encryption of the blockchain?
This gave him some inspiration for building blockchain in the future.
"Hello, Professor Mikali, um..." He said hello first, and then said, "This thing you proposed is indeed very interesting."
"Can I understand the design idea of your blockchain, Algorand?"
"Haha, of course there is no problem." Mikali nodded. "The main purpose of Algorand is to solve the [trilemma] of the blockchain. Do you know about this problem?"
"I know." Xiao Yi nodded. "That is, any blockchain system can have at most two of the three ideal attributes, namely any two of decentralization, scalability and security."
During this period, he did a lot of research on blockchain, including the blockchain trilemma. This dilemma is almost similar to the trilemma in international economics, but because it occurs on the blockchain, it is slightly different in nature.
Mikali smiled, "Yes, that's it, so my design idea is to use the Proof of Stake principle in the first stage, which is the block proposal stage, and in the second stage, the block finalization stage, use Byzantine agreement to vote on the proposed block."
"In Algorand consensus algorithm, the membership of both committees changes each time a stage is run..."
Mikali began to share his thoughts with Xiao Yi, and Xiao Yi also began to think.
Since he also plans to build a blockchain, if someone else can teach him his experience, it will obviously be helpful for his future construction.
However, when the two of them were communicating, other people in the venue became increasingly restless.
Those mathematics scholars began to ask around what kind of paper Xiao Yi published a few days ago, which could actually attract the attention of such a Turing Award winner.
Especially this Silvio Micali, who got Turing Award for his contributions to information security and cryptography.
This is really surprising.
However, the more they inquired and learned more, the more they realized that Xiao Yi had done something extraordinary.
Good guy, I'm sorry that the problem of the gradual decrease in the security of the RSA encryption system that has been discussed in the academic community for these years has been quietly solved in the past few days?
And the solver is Xiao Yi?
It's really outrageous!
Of course, this is the information asymmetry between different majors.
For scholars in the mathematics community, this problem does seem to have been solved quietly, but in fact it has attracted the attention of quite a few people in the computer field.
Otherwise, there wouldn't be so many computer scientists at the scene.
After constant exchanges, the mathematics scholars realized that there were so many computer scholars in the audience, estimated to be several hundred people.
For a moment, they were even more amazed.
What Xiao Yi created has caused such a huge shock in the computer field!
At the same time, the two people in the row of seats Terence Tao and Maynard looked at the scene in front of them and shook their heads helplessly.
Terence Tao sighed with emotion, "I really didn't expect that their computer majors responded so quickly. In just a few days, they actually came to us directly."
"We even directly joined our Joint Mathematics Meeting." Maynard also sighed with emotion.
As early as Xiao Yi showed them the results, they already knew how important the results were.
However, the reaction of these computer scholars still surprised them a little.
"Forget it, why bother with so much? Anyway, according to the news announced by World Bank, it is basically confirmed to be our plan." Terence Tao smiled, "This time, Xiao Yi led us to make a lot of money."
"Indeed." Maynard nodded.
After their plan was submitted, World Bank announced the final result within a few days. Not surprisingly, their plan was accepted by World Bank.
The entire project is over here. After all, there is no need to continue wasting time. If you have a plan, just use it.
As for the reaction of other groups when they learned the news, they didn't know, but in the past few days, they had received a lot of phone calls with "cordial" greetings from other groups.
Even when communicating on the phone, they still maintained a basic friendship, but they could also hear the feeling of gritted teeth in the other party's tone.
However, these don't matter anymore.
After all, you can get a $10 million bonus right away, so why care about these things?
Even according to the final distribution, they can only get more than 1 million, but this is still a huge sum of money for them.
After all, there really isn't that much money to be made for pure mathematicians.
On the stage, Xiao Yi and Professor Mikali had an in-depth discussion, and they both gained a lot.
Xiao Yi gained experience in blockchain construction from Mikali, while Mikali learned more about the use of Xiao's expansion in cryptography from Xiao Yi.
Very rewarding.
"Thank you very much for your answer!"
Finally, Mikali expressed his thanks.
Xiao Yi also smiled and nodded, "I am also very grateful for the knowledge you shared with me."
Until now, he didn't know that the other party was actually a Turing Award winner. However, just through such exchanges, he could see that the other party was very knowledgeable.
Especially in mathematics, this professor is also very capable.
After getting along with Professor Kleinrock during this time, he still wondered whether computer scientists were not very good at mathematics?
But now it seems that Professor Kleinrock is just an example, right?
Ahem...
It's not that he looks down on Kleinrock. After all, he is older and his math ability has deteriorated, and he can still understand.
"So, now let's answer the next question."
After answering the first question, it's the second question's turn.
Then, a lot of hands were raised in the audience, which dazzled him.
Finally, he picked out one person, and to his surprise, he was another computer scholar!
"Mr. Xiao, what I want to ask is, since Xiao's expansion can be applied to RSA, is it completely feasible to apply it to ECC?"
Okay, problems in the computer field are problems in the computer field.
Anyway, we still have to follow mathematical principles.
Then Xiao Yi said, "In fact, it is also feasible, but we need to slightly change the form of Xiao's expansion. Well... I will simply demonstrate it to you on the blackboard."
Then he turned around and demonstrated on the blackboard.
However, his "simple demonstration" made the questioner's expression freeze again.
Haha...
Your demonstration is really [simple]...
In this way, after Xiao Yi completed the demonstration, he replied, "In the end, we can conclude that although it is feasible, the effect is far worse than RSA, and the technical difficulty of ECC becomes higher, so I do not advocate the use of this method."
"Okay, thank you." The listener had to pretend that he understood, nodded, and then took a photo of the steps written by Xiao Yi, intending to study it carefully when he went back.
Most of the other computer scholars interested in this issue do the same thing.
As for admitting that you are not good at math...
Forget it, save some face.
Next, Xiao Yi continued to answer questions from other questioners, and he finally answered some questions from mathematicians.
Hmm...
Sure enough, it was still a mathematical problem, which made him feel even more excited.
As for the problems in the computer field, although they were quite interesting, they did not interest him as much as those mathematics problems.
Finally, the time unknowingly exceeded the original 45 minutes and even gradually reached an hour.
It wasn't until Hailes Carr signaled to Xiao Yi from the side that he remembered that the time had expired.
Good guys, half an hour to report and half an hour to answer questions.
Looking at the hands raised in the audience, he could only spread his hands and said, "I'm sorry, everyone, today's report has seriously exceeded the time limit."
"So, let's just stop here."
After hearing Xiao Yi's words, those scholars who raised their hands could only put down their hands helplessly, feeling very sorry in their hearts.
As for the questions Xiao Yi answered just now, study them carefully when you get back, and maybe you can publish a paper.
It really makes money for those who are clicked.
Of course, no matter what, Xiao Yi's report also brought certain gains to everyone.
Even the students are the same.
After all, Xiao's expansion is really a method that is easy to understand, as long as they have enough understanding of complex analysis.
So, as the first person applauded, other people were also led to start applauding.
Everyone was grateful and gave the warmest applause to Xiao Yi.
In a certain row of seats, the two invited speakers who gave a report in the afternoon applauded and looked at Xiao Yi with admiration.
If before the report, they were envious of Xiao Yi's treatment of more than 2,000 people attending, but now, they can only admire it.
"Anyway... I'm convinced, he deserves it."
"Yes! This is what he deserves. Who else's report can inspire everyone like his?"
"I have already thought about my next topic, maybe I can post a top article."
"Then good luck to you!"
"How?"
Brian Winston turned to look at the two computer giants next to him.
"It's worthy of the name." Prabhakar Raghavan, Google's senior vice president of knowledge and information, gave his evaluation.
"No." Silvio Micali shook his head and said, "It should be true to its name."
"You can feel the depth and vastness of his thinking just by simply communicating with him."
"The reputation spread outside is even worse than his actual ability."
Hearing the Turing Award winner's comments, the two business executives next to him looked at each other.
"Perhaps, I really have to ask him if he is willing to join Google."
Raghavan said.
Winston shrugged. "Good luck."
