Bitcoin doesn't compile

1. As a reminder, bitcoin has been exploited to the end. The principle of bitcoin program determines that the longer the generation interval is, the longer the time to generate a bitcoin may have exceeded its value. After all, we have to consider the power consumption and time of the mining computer. Although bitcoin is still very popular, it's a bit late to start now, and it's unlikely to make money.

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
Unlike most currencies, bitcoin does not rely on specific currency institutions to issue. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
3. If you download apps, you can download them directly from the app market, but some apps that have not been put on the shelves can be downloaded directly from the browser.
4. The concept of smart contract can be summarized as:
a piece of code
(smart contract), which is deployed on the shared and copied
ledger
to maintain its own state, control its own assets and respond to the received
external information
or assets. Smart contract, in short, is a set of commitments defined in digital form, including agreements on which contract participants can implement these commitments.

5. Different stocks are going up because of their good performance, that is to say, the strength of the company is improving and becoming more and more valuable. virtual currency is going up because it is as rare as stamps. One hundred sets of this one is not available, so it's expensive. But the question is, does anyone accept the offer? In case there are many virtual currencies coming out tomorrow, XX currency, XXX currency, that is, the number of bitcoins is certain It's not like gold. There's so much gold. But virtual currency is virtual code. It says that writing can write gold. Can you make it more? So virtual currency is not the mainstream, but the most auxiliary thing. The value is not too high. Don't think that people are good when they buy. People follow too much. In the past, Auntie was crazy when she bought gold. Now why is she rational Money ah, stocks, migrant workers have bought stocks, and now how not to buy or lose money, real estate is also the same, and so many years after the collapse will be rational
6. The old BSC is converted into optical signal through 2m line to SDH multiplexing equipment, and then the optical transmission network to the transmission equipment on the base station side is converted into 2m line to form electrical signal to the base station (BTS)
the new BSC is basically optical port BSC. Go directly to SDH or PTN equipment on the transmission side, go to the base station side through the transmission network, and convert it into 2m electrical signal to the base station (BTS). Some base station equipment support the optical port, and may be directly inserted into the optical fiber.

7. First of all, bitcoin is a decentralized monetary system. For example, both RMB and US dollars are issued by banks, but bitcoin is similar to treasure in a treasure hunt. Everyone has the opportunity to "issue" bitcoin himself
in fact, the essence of special currency is a lot of special solutions generated by a lot of complex algorithms. The system will choose a correct answer every ten minutes. Whoever can find the correct answer in the first ten minutes will get a reward. The upper limit of bitcoin is 21 million. When bitcoin was born in 2009, each reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the bounty will be halved to 25. When the total amount reaches 15.75 million (5.25 million new output, or 50% of 1050), the bounty will be further halved to 12.5, and so on. Therefore, bitcoin circulating in this mode can not be recovered to zero, because everyone is the issuer of bitcoin. Unless everyone clears their account number and no longer digs, bitcoin will always be active

8. 很多朋友都知道如何在linux平台如何编译比特币程序,但是,到了windows平台,
就会感觉到无从下手. 其实, 比特币程序是跨平台的.
你要编译windows版的比特币程序,基本上有两种方法,一种是在linux平台
(推荐ubuntu 13.10)通过交叉编译的方法来编译.另外一种,就是直接在windows平台编译.
我想,你既然要在windows平台使用,我就详细介绍一下如何在windwows平台编译比特币程序.
我的平台：windows7
第一步:安装变编译环境QT和MINGW,msys
1、msys是一个在windows平台模拟shell的程序
下载安装程序之后，通过安装管理程序，按安装以下内容：
From MinGW installation manager -> All packages -> MSYS
选中以下安装包
msys-base-bin
msys-autoconf-bin
msys-automake-bin
msys-libtool-bin
点 apply changes开始安装他会自动下载安装好
需要注意的是，确保不要安装msys-gcc和msys-w32api ，因为这两个包和我们的编译系统发生冲突
很多人出现一些莫名其妙的问题，就是因为这两个包
2、安装 MinGW-builds
下载并解压缩 i686-4.8.2-release-posix-dwarf-rt_v3-rev3.7z 到C盘根目录 C:\
注意我的目录结构你尽量和我一样
3、设置PATH环境变量，将C:\mingw32\bin;添加到第一个
4、在命令行模式下输入 gc -v 会得到以下内容
c:\gcc -v
Using built-in specs.
COLLECT_GCC=c:\mingw32\bin\gcc.exe

9. If you want to make a lot of money through speculation, you can go to cnfol bitcoin and learn more about it
10. Virtual digital currency has developed rapidly in recent years, and all walks of life have been affected. Now there are still many new currencies, such as BHT, which seems to be more popular.
