God of Money

1 Bitcoin KRW 20 million.

No wonder the media expressed expectations and concerns about cryptocurrencies, and quickly spread to the general public.

It soon became a beacon to inform the status of cryptocurrency transactions. Adults and child housewives were also involved in cryptocurrency transactions, and the exchange was continuously updating its record performance.

The number one exchange in the country and surpassing the top in the world.

Bitmain.

Companies that are exponentially growing in number of users with the advantage of trading fast and diverse cryptocurrencies. The company's development team was also having a crazy day.

"Chief, I think we need to set up more servers with too much traffic. This trend will almost kill you again."

"Don't you want a few more of me? But it's not the time yet. The server didn't buy it."

"Did you hold her again? There's a limit to what tuning can do."

The dominance of the ultimate surrogate laughed bitterly.

Thirty-six years old, head of the Witmain Exchange Server Development Team.

It was the title of dominance.

"I'll take a closer look. Mr. Choi has to go home. Get the rest of the team off work."

"What about you, sir?"

"Haha, Representative Choi worries about me, too."

"That's why you're not married yet. You work late every day, and you don't come home from work, so you don't have time to meet."

"I should get a little more than you."

"Oh no, sir. You're doing enough right now · · and then you really get out."

"It's okay. It's not a one-day stand. You're my new surrogate. Get out of here. Don't tell me your boss put you on overtime for nothing."

“Heh heh. I'm a newlywed. Where'd you get that engraving? ”

I saw the best surrogate with a smile. Three years ago, after joining the company as chief, I saw the interview in person and saw the new employee becoming a surrogate until marriage. It was always lacking manpower, and the promotion was not that difficult.

The rest of the team went home one by one and remained in the office of the dominant hall.

Unlike securities companies, cryptocurrency exchanges go back 24 hours a day, there was room for 24 hours of trouble, and they were always nervous because they didn't know when or when to go home from work. Among them, he was doing his best as the leader of the server team.

Fixing bugs that occur every day quickly passed my work time, and I was able to develop them to reflect improvements after work.

Late night is required. Weekend attendance was basic.

"It's been three years."

He looked out the window at a building on Tehran Road, and three years ago he was an employee of a medium-sized company specializing in financial SI. Then he got a job offer from 'Witmain’ through an acquaintance, and after much effort he became the server team leader.

Three years ago.

Prior to the cryptocurrency outbreak, the exchanges were only at a minimum. Because it wasn't a situation where you could pick a lot of developers because you didn't have enough money, you could use Android and iPhone apps, which are endpoints in the back-end database. And the web.

I was involved in everything from one to ten. None of the programs running in 'Bitmain’ here didn't include a single line of code.

Although not a real child, he built a cryptocurrency trading system with such attachment that he would feel this way if he had one.

"Let's go early today, just for a little while."

Though it was 12: 00 p.m. to go home early, it didn't feel that hard considering the stock options I would receive in the future. He reviewed today's bug report and revised it one by one.

* * *

He tilted his head.

“Hmm · · Strange · ”

The eyes stopped at one point on the monitor.

An abnormal transaction occurred when the server crashed.

anomaly.

It was a fatal problem that an anomaly occurred at the exchange. Report writes data in a table format, such as Excel, from the server-side code, as otherwise no clues were posted.). He looked at it for a long time and tilted his head again.

"I can't do this."

I got up from my seat, stretched and sat down again. However, the data did not lie.

"53.123.111.211, 53.12.78.99, 53.33.67.100. How these IP addresses (computer addresses on the Internet) were able to make transactions."

I looked back a few times, but nothing changed. Due to a sudden increase in traffic, the server also crashed once today and the transaction was temporarily halted.

However, the buy and sell orders spilled from these three IP addresses were executed without any problems. He went through all the records a month ago.

In particular, I focused on the days when the server was stopped. These IP addresses have never failed in a transaction. Traffic increased, and even when ordinary users could not log in, transactions approached from that IP address placed a Sell order at the bottom, at the top, and the transaction was concluded to realize a profit of tens, perhaps hundreds of billions.

It was an unbelievable piece of data that I could see with my own eyes. How did this happen without even knowing it was the server team leader?

There was only one thought in his head.

Hacking.

The Witmain Exchange has been hacked.

He immediately called the CTO.

​

Tyrie.

Tyrie.

Tyrie.

I only heard the tone of the call and did not answer the phone. However, the exchange hack was a matter to be shared right now. The dominant continued to try to connect.

When I made the fourth call, the call was finally connected. However, the voice from the other side was not in a state to share the situation.

What brings you here, Team Leader Kang?

What is it, brother? Who are you calling?

Yes, a company employee.

I thought you said you were the boss.

Mwa-ha-ha-ha. It's true. Do you want me to switch?

The CTO, Jung Jin-seop's tongue, was bent, and the tingling of his nose was not stopped. The dominant was the upper lip. It was urgent. The dominant horse was a horse.

"CTO, we are currently experiencing signs of a hack on our side of the Exchange. In a situation where the server is down, the requested transaction has been concluded at some IP addresses. We need to convene an emergency meeting right away."

The CTO Jeong Jin-seop is 33 years old. Usually, they respected each other, but they didn't hesitate to say something about being drunk.

It's past 12: 00 at night. Take some time off, Team Leader Kang. We're going to have some fun.

“CTO, this is an urgent matter. ”

Don't you think the address starts with 53?

"Yes? How?" "

What are you doing answering your phone?

Uh-huh.Why are you so nice?

Aww. E, there.

On the phone, I heard a strange sound again. Yooseong could hardly bear to hang up the phone.

That's a VIP list. I mean, don't worry about Team Leader Kang.

"I don't know what the VIP list means."

The head of the team is not flexible. Flexibility. Never mind. Get out of here.

Ugh. Ugh. Hyung! I can't take it anymore!

Uh-huh-huh.Then let's eat it.

The phone was disconnected. Yooseong sat in a dazed seat with his phone for a while.
