Blockchain developer Cheolwoo Lee (7)
My new goal has been set. The first thing I did after that was to meet Minseok.
“Cheol-woo, it’s been a while?”
“hahahaha, Minseok has become cool.”
Minseok, whom I haven’t seen in a while, has become more handsome day by day. He was always dressed in a neat suit, and his speech became more mature.
Did you say that a seat makes a person?
It felt like Minseok, who was with me as the co-representative of LF, was growing day by day.
“hahahaha, no. Well, it’s me, I always do things like this.”
Minseok also seemed to agree to some extent.
“I’ll have to imitate you too.”
I make a lot of money and I have good skills, but if I compare myself to Minseok from person to person, well? It still felt a bit lacking.
Now that I think about it, the burden of not being able to go to work at LF seemed to have played a role for Minseok.
Although it is said to be a co-representative, the real owner is me after all, so I have to become a better person than Minseok… … .
“What, that sound. I should imitate Cheol-woo.”
“hahahahaha. I didn’t come here to grab a busy person and have a pointless conversation. I’ve got some work to do.”
“I’m busy, but Cheol-woo, I have to come running right away when you call. You can talk nonsense. What happened at Interpol?”
“Interpol? Dispatch is over.”
“already?”
“Yeah. That’s it.”
“Does that have anything to do with the thing you just said?”
“Yeah, that’s right. I’m going to build a blockchain.”
“Blockchain? The Bitcoin I mentioned last time?”
“Yes. It feels so different that I wonder if I can compare it with Bitcoin… But anyway, the original technology is the same. A democratic verification system by the majority.”
“Ooh, what is that?”
Minseok listened to me with interest.
“Transparent online contract. Blockchain NetFuel with smart contract system introduced.”
I thought of a name.
The first part of Network, which means network, is taken from Net, and the English word Fuel, which means fuel, is combined to form NF.
‘The new digital age.’
The future that NF block chain draws is a new digital era that has never been seen before. Must have NF. Because it will be able to run various applications.
“NF……. I like the name. So what do you want to do with it? I don’t know if you say that a smart contract system has been introduced.”
“Ultimately, the NF blockchain network will govern everything online.”
“Everything online?”
“Yes. NF. As the name suggests, it is the fuel of the Internet. For example, with NF, you can play high-end games anytime, anywhere, as long as you have a display.”
“…… You can play high-end games anytime, anywhere?”
“Well, the game is an example. It’s going to be a giant one-earth computer. The NF blockchain network.”
“What the hell does that mean?”
Minseok’s expression was that he didn’t know yet.
Well, even when I think about it, it was an unfamiliar concept, so it was difficult for ordinary people like Minseok to understand.
“First, we can establish a copyright culture.”
“Establishment of a copyright culture?”
Establishment of a copyright culture that neither giants such as Google and Microsoft, nor nationally, have yet realized.
“Yes. Once the NF network is established, at least programs such as CAK and TSS that I have created will have no choice but to forcibly pay copyright fees.”
“I am forced to pay? What the hell is going on with that?”
“As for how that happens…(Omitted)… it has no choice but to be that way.”
“… I don’t know if you say so.”
“I’ll show you soon.”
It is better to show once than to explain a hundred times.
“Okay. What else should I show you. Lee Cheol-woo?”
Minseok said with an expression full of anticipation.
“For that, I need your help first.”
“My help? What do you need my help for?”
“I’m going to create the NF Foundation. Invest in it, LF.”
The Ethereum Foundation in the United States said it was conducting an ICO to raise development costs. But I didn’t have to.
Of course, there will be a need to do an ICO someday, but the purpose was not to raise funds.
“Can you invest in me?”
Minseok said with a strange expression.
“Huh? Why? No?”
“No, it’s funny. Cheol-wu owns more than half of the shares in LF, and you’re getting permission from me. I always say, but don’t forget that you are the real owner of LF.”
“hahahahaha…. But Minseok is the one who founded, recruited, and operated LF.”
“Don’t you think that would have been something I couldn’t have done without you? It’s all thanks to you, Cheolwoo.”
“……Anyway, will you do it?”
“Of course. How much do you need? Just tell me.”
“Hmm… Actually, I don’t know that part.”
I didn’t know what to use in the office, how to hire people, or how to do anything.
“Then, I’ll prepare everything. I’ll get you all the best developers in the world, and I’ll prepare your office.”
“Yes, I’ve got two people. Annual salaries are 240 million won and 120 million won respectively. Bring Changsoo with you. There must be a lot of work to do.”
This time, since it’s a big system, it took a lot of time to make by myself, and there could be parts I missed.
“Hey, okay. Leave everything else to me.”
“thanks.”
* * *
Minseok’s drive and work ability were unmatched. In just a few weeks, an office was found and the NF Foundation was set up.
First of all, developers will continue to be selected, but right now, me, Changsu, and a young developer from KAIST who was dispatched from Blue Light.
On the security side, Team Leader Cho Hyuk and Manager Yoon Sang-cheol.
Other miscellaneous elements, including marketing, were still vacant. Minseok said that he would support me when the time came.
“Hello. I’m Park Soo-hyeok from Blue Light. I look forward to seeing you in the future.”
After I transferred the copyright of CAK to Bluelight, Bluelight experienced rapid growth. And with that financial power, we selected talented developers and sent one of the core personnel to us.
“i look forward to.”
“Then let’s get to work right away.”
You can do it slowly, but did I tell you to remove the horns too? It also took the ICO schedule of the Ethereum Foundation.
I was thinking of getting to work right away.
“Um… um… yes. So what should I do first?”
“Do you know a little about blockchain?”
“No. I don’t know anything yet. What is a blockchain?”
“Well, then, please analyze the source of the Bitcoin Core program first. It will be easy to make once you understand the concept.”
“all right.”
“Changsoo. You too, please.”
“huh.”
He also spoke to Changsu, who was listening next to him.
“And I thought about it, Team Manager Joe. Manager Yoon.”
This time they called the security team.
“Yes. CEO.”
“yes.”
Since it’s inside the company, I also sorted out the names.
“Security has one request.”
“Yes. Just ask me to do anything.”
Chief Joe said.
“Well, you’re familiar with blockchain, right? And what it takes to build deep apps that can commercialize it universally.”
“As expected, isn’t it a sharding network?”
sharding network. That, of course, is also essential.
For example, it will not be possible to upload all calculations of the CAK program to the NF blockchain.
“Hey, what is a sharding network?”
While I and the security team were talking, Assistant Manager Park asked us.
“Did you just hear? I’m trying to build a deep app.”
“yes.”
“Hmm… How should I explain? You know CAK, right?”
“Yes. I did it professionally.”
It was like a person sent from blue light.
“If you run the CAK program on your computer, you know how it works, right?”
“What are you asking?”
He asked as if he didn’t understand.
“First, the storage devices and hard disks are loaded into memory, and then loaded into memory and then calculated by the CPU.”
“Yes. It’s the basic principle of computers.”
“The deep app we are trying to do has a different principle.”
“I don’t understand, yet.”
“When the computer boots, it connects to the NF network. After that, it receives various data from the NF network.”
“Uh, um. I still don’t understand. So what the CEO said is when the NF network is finally completed. Are you saying that computers don’t need CPU and memory?”
“Yes. It will.”
“……is that possible?”
Assistant Manager Park said with dazed eyes.
“Possible? Nothing is impossible.”
“No, that requires a processing unit, or CPU. How are you going to do that? Memory and motherboard storage.”
“Maybe it will change that way too.”
“change?”
“Yes. A processing unit is required. So, in the end, there will be a system like a conventional computer, but that processing unit will be a sharding network.”
“…?”
He looked like he didn’t know yet.
“First, analyze it. Then study it. And when the NF network is completed, you will know. What the hell is it?”
You probably still don’t get it right. Because I put a lot of effort into establishing this concept.
Common sense makes no sense? No, even if it made sense in common sense, it was nothing short of impossible.
It will be a verified method by becoming one NF sharding network, not the existing personal processing device.
innovation… … . No, it would be a revolution if possible.
If the NF network works perfectly and gets people’s attention, online will open a whole new era.
Beyond simple copyright issues… … . New online age.
“Okay. First of all, I’ll study more.”
“Yes. It probably won’t be long. Let me show you what those times are like.”
“Yes. I look forward to it.”
“Wait, the words have leaked elsewhere. Security team.”
“yes.”
“The most necessary thing to build a deep app is a sharding network, but there is one problem.”
“Yes. What is it?”
“It’s random number generation.”
From noble mtl dot com
“Random number generation? Does that matter?”
they asked with a bewildered expression.
Ironically, computers need random numbers to generate them. A computer is a sophisticated system of 0s and 1s.
How to generate random numbers from there?
In non-computer life, there may be lottery, dice rolling, and so on. In other words, random numbers are generated because environment variables cannot be predicted.
However, computers do not have unpredictable variables. If there is, it is likely to be a variable that can be predicted.
So, in the usual way, time is used as a seed to generate random numbers.
Using time as a seed meant generating random numbers based on user actions.
Ironically, computers needed random numbers to generate them.
“Yes. Everything in blockchain is transparent and operates by perfect calculation. But how do I extract a random number from it? Is there a seed that will be a random number?”
When I said that, they fell silent for a while, perhaps thinking.
“……. hmm?”
“uh……?”
“to……?”
And after a while they all had similar reactions.
“That’s right. Computers need a seed value to generate random numbers, and that’s usually time. But in a blockchain, time can’t be used as a seed value.”
“Yes. Manager Joe understood it correctly.”
“Wow, I hadn’t even thought about whether there was such a problem.”
“We need a theory that can generate perfect random numbers.”
“That’s right… If it wasn’t for that, I wouldn’t be able to create a system with random elements. For example, I wouldn’t be able to make a gacha game.”
“Yes. You can’t make a game that rolls dice, and even non-games, any application that uses random values won’t make anything.”
“…… It’s a bigger problem than I thought? Without a random function, who would want to make an application with a deep app?”
Everyone nodded their heads at Joe’s words.
“Team Manager Jo and Manager Yoon are experts in computer cryptography, so please research how to generate random numbers.”
They thought about my order for a moment before opening their mouths.
“Uh… is it possible?”
“No seeds to generate random numbers? If I can’t use a time seed, what should I use? I can’t even use a block number.”
Clearly, random number generation in blockchain has been a difficult problem.
“Isn’t it possible? I see the problem, but I haven’t thought about how to do it yet. I still have too many things to do.”
Right now, my job was to create the skeleton of the NF blockchain and a programming language to run the smart contract system on the NF network.
It was tight with just that.
“… Let’s do some research.”
“Let’s study together.”
Team Leader Jo and Manager Yoon spoke in a tone that was not confident.
“Okay then, since everyone has work, let’s go to work.”
“All right.”
“yes.”
“go for it!”
The development of the NF blockchain network, which will open a new digital era in the future, has begun.
