Blockchain developer Cheolwoo Lee (13)
A few days before version 2 was released.
Team leader Joe came to my room.
“Chief Lee, you should take a look at this.”
“What is it? Did you have an update issue?”
“No. It’s not like that, um…… It took a little while. Oracle released Oracle database version 18 the day before, and it was encrypted and notarized using the VDF function.”
“is it so?”
“Yes. So, just in case, I looked up the VDF function of Oracle 18.”
“yes.”
“No way, but he was using the VDF function we were trying to use. Wesolowski’s VDF function, which gives an error about 1 in 10 million.”
“Hmm… Is that the Oracle company I’m thinking of? Is it holding database and JAVA licenses?”
It is a global big IT company. I was a little puzzled that such a company would use a function with an error.
“Yes. The company CEO Lee is thinking of is correct.”
“is it so?”
“yes.”
“Um, I see.”
“How should I not tell you?”
“No, I don’t think it’s necessary to inform them. Maybe they knew and didn’t release it?”
Anyway, that oracle. I would have known that there was an error in the VDF function, but it was speculated that there would be internal circumstances that the release was made.
“It is, but…”
“What else do you have?”
“Anyway, that part? If our NF Network version 2 is released in a few days, a new VDF function will be released and it will be revealed that there is an error in Oracle’s VDF function…”
I hadn’t even thought about that.
“Uh, I guess that’s what happens? We’re an open source project.”
“I’m afraid that Oracle will say something. Even if they are aware that there is an error in the VDF function. I guess they will update it later as the error has not been made public yet.”
It was a bit of a bit of a bit of a bit of a bit of a bit of a bit of a bit of Even if there was a problem, if users didn’t know, it was enough to fix it with a submarine patch later.
“But we can’t delay our schedule, so… let’s proceed.”
“That’s also true. I wanted to talk about it.”
“Yes. Good job.”
“And what about the reaction of version 2?”
“Reaction? No kidding. To say that he has already developed a sharding network, and to say that CEO Lee is not a genius of the century. hahahahaha.”
“Yes. Let’s release it. Version 2.”
* * *
A few days later, our NF Blockchain Foundation released version 2. And about a week passed.
「Successfully introduced NF blockchain sharding network technology.」
「What is Blockchain?」
“What will change in the future?”
“Network delay problem still occurs. challenges to be addressed in the future.”
「The introduction of sharding network technology makes the NF blockchain network run smoothly.」
“Chul-woo Lee, who the hell is he? ITE-X engine followed by blockchain network development.」
Numerous articles were pouring in, and the number of nodes was growing explosively.
However, the difference from before was that even though the number of nodes exploded, the burden of data processing was significantly reduced.
“CEO Lee has been successful. With the introduction of the sharding network, many transactions are proceeding smoothly. The network latency is around 20ms.”
Assistant Manager Park posted a report.
“If the network latency is 20 ms… it’s almost at the level of optical communication, right?”
“Yes. That’s right. It’s on the same level as a normal Internet network. Success.”
“20ms…. It’s a bit disappointing. I still have to give up on games that require real-time motion.”
“Well, there are many other places where you can use it.”
“Well, it is. Well, which one will respond the fastest?”
“That’s right.”
“Ah, Chief Joe. What’s the response from Oracle?”
Now, after a week, maybe Oracle has found an error in the VDF function.
“It’s still quiet.”
“Well, first of all, we’ll watch the Oracle a little longer.”
While we were having a technical meeting, a salesperson visited us.
“I’m sorry during the meeting.”
“Oh, no. What’s wrong?”
“That’s it… the people from the Meteorological Administration are waiting outside right now.”
“……? What do you mean? Meteorologists are here right now?”
“yes.”
“I know you don’t have an appointment in advance, right?”
“Me too, so I’m a little curious. So I thought about sending it back… but that’s…”
“Yes. Why?”
“I couldn’t do that because the head of the Korea Meteorological Administration was here.”
“No, the head of the Korea Meteorological Administration?”
No matter how it is, the person who becomes the commissioner comes without a message? From what reason?
“Yes. What should I do?”
“How do you do it? Quickly guide me where you are.”
“All right.”
No matter how much I say I’m doing well these days, a person of the level of a commissioner came to visit me. I couldn’t afford to entertain.
The place I arrived after being guided by the sales staff was a conference room set up on one side of the foundation.
There, the director of the Korea Meteorological Administration and some staff were drinking tea.
“Hello. Commissioner. I’m Lee Cheol-woo. What happened to such a shabby place without a message?”
“hahahahaha, hello. Director Lee Cheol-woo. I wonder if he’s a nuisance because he came without contact.”
When I said hello, the commissioner replied.
“…… No. The Commissioner is here, how dare I?”
“Sit down for now.”
“all right.”
I sat across from the Commissioner.
“Can you guess why we came here?”
“Um…. Is the weather forecasting system the reason you came here?”
What kind of image do you think of Korea Meteorological Administration? It was a place where reliability was so low that there was a popular belief that the probability of a weather forecast was 50%.
I felt sorry for the people at the Korea Meteorological Administration, but the weather forecast didn’t fit that well.
There was only one reason for them to come here.
weather forecasting system.
To predict the weather, massive calculations must be performed with data from sensors installed in each base station. So I know that the Korea Meteorological Administration has a lot of super computers.
Wouldn’t it have come about that?
“Yes. That’s correct. It is an open fact in Korea that the Korea Meteorological Administration is at a low level of trust.”
“No…if the Commissioner says that…”
“hahahahaha, I know that. I’m one of the people of Korea.”
“…”
“You probably don’t have much time, but I’ll tell you directly. I want to put the supercomputers operated by the Korea Meteorological Administration on the NF network. And I want to predict the weather with the computing power of the NF network.”
NF network computes weather forecasting system?
It was quite possible. Weather forecasting had nothing to do with network delays, and fast computing power was sufficient.
And the NF network was able to subsidize that computing power. No, it is not a matter of assistance, but enormous computing power will be mobilized immediately when needed.
“Uh, if I can answer that, I can.”
“Wow, as expected, Mr. Lee Cheol-woo. You answer right away.”
“hahahaha, the title of teacher is a bit…”
“I want to regain the trust of the Korea Meteorological Administration through the NF Network. I hope you will help me.”
“It’s not difficult. The Korea Meteorological Administration’s supercomputer uses UNIX, right?”
“Yes, that’s right.”
“The UNIX version of NF Network has also been developed. Just install and run that version there. Just…”
“but?”
“One stumbling block is that the program used by the Meteorological Administration has to be rewritten in the Flyer language to run on the NF network.”
If it is a big problem, it was necessary to port the existing meteorological agency program to operate in Flyer language and eWASM virtual machine.
“Don’t worry. Porting has already been completed.”
“Yes…? What?”
What do you mean by porting already done?
“Yes. We have been preparing since it was opened in the previous version 1.”
“No… how the hell did that happen?”
“I was there at the time of the ICO, I don’t know if you remember.”
“Oh, sorry. There are so many people.”
“hahahaha, don’t worry. I fully understand. Anyway, I was very impressed to hear Mr. Cheol-woo’s presentation there. Paying for data as much as using computing power? “
“Thank you. But for what reason did you think it would be good for the Korea Meteorological Administration?”
“Well, that’s it. The Meteorological Administration’s supercomputers aren’t using 100% of the time. They use more calculations when they catch special issues like changing seasons, typhoons, rain, etc.”
“Oh, is that so?”
“Yes. It is rarely operated on sunny and calm days. However, it predicts precipitation when the atmosphere changes, and at that time, it is often used at 100% or more.”
“Well, are you saying that supercomputers require over 100% computing power when they’re running, and less computing power when they’re not running, that is, on a good day?”
“Yes, that’s right.”
It seemed like that.
The Korea Meteorological Administration does not use 100% of the supercomputer at all times. However, when there is a special issue, it is used over 100%.
“Well, is it a matter of efficiency? Is it related to the budget?”
“Yes. That’s right. In special cases, especially typhoons, sometimes requiring more than 200% computing power, we couldn’t double the supercomputer to accurately predict the path of a typhoon, which happens only a few times a year. It becomes an unused resource. There is.”
Also my prediction was right.
Using 200%, it would be possible to predict the path of the typhoon more accurately, but it required twice as many supercomputers than now.
From noble mtl dot com
To predict more accurately, it would have been difficult to spend twice as much on computers alone.
“okay.”
“Yes. It’s the same for typhoons, and it’s the same for predicting precipitation. To predict more accurate probability and precipitation, you need higher computing power at that moment.”
“I see. In that case, it would definitely be better to participate in the NF network we are running.”
The advantage of the NF network now is that it is meaningful to pay as much as the computing power is used.
“Yes. What do we need to prepare?”
“Are you going to prepare something?”
“yes.”
“No. Just install the NF 2 version according to the manual we provided, and then register the weather forecasting program ported to the Flyer language. Then, if necessary, run the program on the NF network.”
There was nothing in particular for me to do.
We prepared a manual, and the manual was on the official website. It was enough to apply it accordingly.
“Is there anything special to be aware of?”
It seemed that the commissioner had come all the way here to see if there was anything to be aware of.
But there was nothing special to note.
“Yes. No. However, I recommend buying some NF and keeping it. If it’s going to rain tomorrow, you’ll need computing power that exceeds the mining rate. It’s good to have plenty of it.”
“hahahaha, I’ve already bought a lot.”
“You are thorough.”
“Oh, and there are a few more things I’d like to ask you…”
After that, the commissioner asked me a few questions about the NF network, and at the end he said that he would apply it even today and went back.
And after a while, the Foundation’s staff came in.
“No, why did the head of the Korea Meteorological Administration come?”
Sang-cheol hyung asked.
“Well, it’s obvious. The Korea Meteorological Administration is thinking of introducing an NF network.”
“Eh…? To the Meteorological Agency?”
“yes.”
“No… are the supercomputers of the Korea Meteorological Administration participating in the NF Network?”
“Perhaps.”
“Wow, how big is the NF network getting?”
“The Meteorological Agency is just starting.”
It will probably come in all places that require a lot of calculations, small or large. video, design, architecture, etc.
“Then, is the Korea Meteorological Administration recovering trust now?”
“I wonder if it will be better than before?”
“oh my god.”
