"Sister Ye!"

Yaya shouted outside Lu Zhou's house, Zhong Yuanliang smiled helplessly, and pressed the doorbell beside the door.

After a while, Ye Qingchen held Xiaoyu and opened the inner door. Seeing that it was Zhong Yuanliang's father and daughter, she opened the door with a smile.

"Hello, Brother Zhong. Yaya is making trouble again."

Zhong Yuanliang smiled and said, "It's really disturbing, she always wanted to come up on weekends."

Ye Qingchen always liked Yaya, or she was very loving when she was pregnant, she said with a smile, "It's not in the way."

Yaya stood between the two and tugged at the corner of Zhong Yuanliang's clothes. She noticed that Ye Qingchen was holding a baby, "Wow, is it my brother?!"

She jumped up and down and circled around Ye Qingchen. Ye Qingchen squatted down when she saw it, and touched Yaya's head, "This is my sister. My brother is sleeping inside."

Yaya's eyes widened, "I see! I want to see my brother!"

Zhong Yuanliang, "..."

It's really a messed up generation.

"Cough cough. That little leaf, I'll pick her up before dinner later."

Ye Qingchen smiled, "Hey, you're busy."

......

Zhong Yuanliang returned to the room. On the computer, ATG was chatting in various ways. This Russian guy talks a lot, but he can't speak English very well. It's a headache to have Zhong Yuanliang chatting with him.

A few months ago, the Bitcoin exchange btce, which the two were busy with, had been officially tested and launched. The server is deployed on an anonymous provider in Russia, and the security is safe enough. Just kidding, Sander is also a well-known hacker organization.

At present, many of the illegal gains on the Sad Road SR flow into their own btce exchanges. In particular, the price of bitcoin has been rising, from a few cents to tens of dollars. There are more and more geeks playing this stuff, and there are special miners who take this as a sideline. Taking the two into account, the trading volume of btce is quite huge now.

However, compared with SR, the profit of btce is much smaller. After all, it is to open the door to do "bright" business, and there is no huge profit from those dirty activities in SR.

ATG also has a brushing robot written by itself in the exchange, which belongs to the individual to earn extra money. As long as it does not affect the operation of the organization, other members will turn a blind eye.

ATG: "Dude! Come and see your Chinese compatriot's post, it's awesome! Look at it, be sure to check it out right away. I think I can invest a sum of money to try his idea!"

Zhong Yuanliang entered the address sent by ATG on another computer. It really has to be guarded against, even among the members of Sandna, there will be "mischievous" attacks. Hehe, he has been toyed with.

The content is simple, it is a resource collection post in the Bitcoin community.

Zhong Yuanliang was happy when he saw it. It was nothing more than that some of the Bitcoin mining geeks proposed to use FPGA (Field Programmable Gate Array) to make mining machines.

Last year, people were still mining with CPUs. As more and more people open source the source code of graphics card mining, most people are mining with graphics cards. A year ago, the total computing power of the entire network was only Gh. At the beginning of 2011, it increased hundreds of times to hundreds of Gh. Now only eight months have passed, and this has increased by a hundred times to more than 10Th.

The reason is simple, the price of Bitcoin is rising, and programmers have taken out the graphics card hardware for playing games to mine.

This post is a good one. It does not stop at graphics cards, but explores the pursuit of higher computing power with more professional hardware.

Unlike ATG, Zhong Yuanliang does not have a strong interest in Bitcoin. But the reason for making money is enough. Use FPGA to crush graphics card miners? The idea is very good, and once it is realized, it is probably a huge profit.

On the idea of ​​the post, the author proposed that the XC6SLX150 FPGA chip produced by Xilinx could be used to make the mining machine, the hardware should be done by yourself, and the algorithm core should be the open source code of the community. In theory, a “specialized” mining machine can be realized. It does not want cpu or gpu, so it can only run the sha256 algorithm of bitcoin mining.

Zhong Yuanliang thought about it, he clicked on the author of the post, "Zhang Guangnan", and after pondering for a while, he replied to ATG.

Zhong Yuanliang, "People from China?"

ATG, "You are really annoying. Just you Huaxia, it's called Jinghang, yes, a student of this school. He just arrived in the community, but I grabbed him and asked a lot of things. If you want me to say, absolutely It can be done!"

Zhong Yuanliang, "Then what do you think?"

ATG's reply was a little slower than before.

"Do it for sure. If there's no idea in Sander, I'll have to mix my own money. If nothing else, how much is bitcoin now? $30 a month ago! Now it's a **** $10! ​​Crazy! It's all. I really want to make this FPGA machine, this is not a mining machine, this is a money printing machine!"

Zhong Yuanliang said, "Yes. But after all, Sander is not so good, there is no need for people to come in. You also know that the organization cannot be expanded any more. The risk is too great."

ATG, "Don't worry. I'm good at this. At most, I'll chat more with this surnamed Zhang, and put some useful things in it. It must be done by people who organize themselves. There is a lot of Xilinx enthusiasts in Moscow. I think it will work."

Zhong Yuanliang thought for a while, and then replied, "Well. I need to mention that the organization has some cooperative institutions in Huaqiangbei in the south of Shenzhen, which can help you get some cheap electronic components."

ATG, "Wonderful! It's wonderful! But it's a good place to find hundreds of engineers with a single word. I almost forgot. You don't know the ghost style in Europe, UU Reading www.uukanshu.com You can't be as diligent in business as you Chinese people. I used to work in a company, my mother was drinking vodka and writing code, and I wrote a 'Katerina object', which almost drove me crazy. Damn he told me that it was the former Girlfriend's name, I want to remember it well in the project. Hell!"

Zhong Yuanliang cut off the communication, he was too lazy to listen to ATG talk about his boring life in Russia.

"FPGA..." He read the word over and over.

This is nothing but semi-custom hardware. If it is to be a Bitcoin mining machine, according to this Guangnan, it is to modify the hardware so that the entire hardware can perform the calculation of the sha256 algorithm faster.

General-purpose cpu, the computing power is Kh, thousands of calculations per second.

The GPU for graphics processing has a computing power of Mh, millions of calculations per second.

If a semi-custom FPGA can really be made into a mining machine chip, it may be able to double this hundreds of times.

"What if it's a dedicated full-custom integrated circuit ASIC?" An idea popped into Zhong Yuanliang's mind.

He shook his head, and regardless of whether it was feasible or not, the chip circuit industry was no better than software. Not to mention the huge investment, the project would be aborted in minutes. And there is no related knowledge structure in his mind.

He thought about it and started looking for relevant information to read on the Internet.
