The operation of bitcoin is valuable

1. The general idea of "fragmentation" is to change each block in the blockchain network into a sub blockchain, in which several (currently 100) collations (which can be called "check blocks", in order to distinguish them from the concept of blocks in the scenario of fragmentation) packed with transaction data can be accommodated, and these collations finally form a block on the main chain; Because these collations exist as blocks as a whole, their data must be packaged and generated by a specific miner, which is essentially the same as the blocks in the existing protocol, so there is no need to add additional network confirmation. In this way, the trading capacity of each block will be expanded about 100 times; And this kind of design is also concive to future expansion. At present, the whole expansion plan is roughly divided into four stages; This article only introces the implementation details of the first phase. Transferred from Jianshu. Currency exchange of digital currency

2. The capital disk is made up of the people in front and those in the back. It has no value. This kind of source code is worth a lot. Don't invest in the capital disk. Most people have nothing to lose

3. bitcoin was not born in 1997. The concept of bitcoin was put forward in 2008 and officially born in 2009
when bitcoin was first born, it was worthless. In 2013, the price of bitcoin once soared to 8000 yuan, and now it is about 4000 yuan
of course, with the development of bitcoin, other counterfeit currencies are also rising. For example, Ruitai, Laite, Ethereum, doggy and other digital currencies.

4. Bitcoin needs excavators. The so-called excavator is the user's computer. The system rewards bitcoin by the amount of calculation contributed by users, and the calculation is a mathematical problem. Since bitcoin is online, there are about 25 million. The price of things is worth supporting because they are rare.

5. Bit B can be used as money because it can be exchanged with other currencies

6. No, bitcoin is generated by P2P nodes. The reason why it is calculated is that it uses cryptography instead of being generated casually. Because P2P is limited, so the number will not be very large, the operation is not created, but found.

7. Computing doesn't proce any value. It's just that some people use bitcoin to launder money. Only useful things have value. The function of bitcoin is to launder money. Once this function is blocked, it's worthless.

8. It is impossible to control the number of issues without a fully decentralized distribution institution. Its distribution and circulation are realized through open-source P2P algorithm
anonymity, tax exemption and supervision free
robustness. Bitcoin is completely dependent on P2P network and has no distribution center, so it cannot be shut down externally. Bitcoin price may fluctuate and collapse, and many governments may declare it illegal, but bitcoin and its huge P2P network will not disappear
no borders, cross-border. Cross border remittance will go through layers of exchange control agencies, and the transaction records will be recorded by many parties. But if you trade with bitcoin, enter the digital address directly, click the mouse and wait for the P2P network to confirm the transaction, a lot of money will pass. It does not go through any regulatory agencies and will not leave any cross-border transaction records
it is difficult for the cat to survive. Because bitcoin algorithm is completely open source, anyone can download the source code, modify some parameters, recompile, and create a new P2P currency. But these counterfeit currencies are fragile and vulnerable to 51% attacks. Any indivial or organization, as long as it controls 51% of the computing power of a P2P currency network, can manipulate transactions and currency value at will, which will be a devastating blow to P2P currency. Many Shanzhai coins die in this link. The bitcoin network is robust enough. If you want to control 51% of the computing power of the bitcoin network, the number of CPUs / GPUs required will be astronomical.

I have already realized your idea. The investment is more than two or three hundred, but it's not expensive. Let me just talk about how I did it

1. the core of everything is NAS: my method is to install heiqunhui on nitao n54l HP server. The investment is about 1500 yuan. Then buy 4 pieces of 4T Western Digital red plate, each about 1000. Of course, you can graally add hard disks according to your needs. The n54l can install up to five hard disks to achieve more than 20t of home storage space. Heiqunhui can run on any x86 system. If you happen to have idle computers in your home, you can save this investment, but it's much more stable to buy a serious server. You don't have to worry about it when you drive it. It's very easy. My server has been running for several months without stopping the

2. network. For remote control, it is better to have public IP. Therefore, you'd better install broadband networks such as China Telecom and China Unicom. If you use Xunlei remote, you may not need public IP, but if you want to control Qunhui system, you must use public IP

3. link. Home LAN should be Gigabit. Buy a Gigabit switch, 200 yuan. Network cable with ordinary Super Six is good

4. software. NAS runs Qunhui system, which is very easy to use. You can install DS audio, DS video, DS file, DS download, DS photo and other supporting applications on your mobile phone, and remotely control the server download at home. You can even remotely request your home video. Qunhui will encode it in real time and adjust the image quality of the video according to the network speed. Qunhui also supports network disk and thunderbolt offline. You can also install a thunderbolt remote x ware, remote control home download
