1. bitcoin is valuable under certain circumstances, but it is worthless under certain circumstances. Because it's not legal tender. It is impossible for any country to get the right to issue legal tender to use any
mining machine. Bitcoin is just a virtual number. While it's still possible to change money, change it quickly! It's too late to wait until it's worthless at the end.
2. Because bitcoin does not exist in the issuing institutions (bitcoin is extracted from the network), nor does it exist in banks, but directly through a personal to personal transfer.
3. This is not necessarily true. After all, it is a digital cryptocurrency, each of which is separate and not stored on the website.
4. At present, it seems to be more insecure than the bank, whether it is stored on a computer or in a physical wallet, it is not as secure as the bank. Better for hackers to steal.
5. For example, I borrow money from you in a village. Normally, if I am afraid that you will not repay the money, I can find an intermediary recognized by everyone, such as the village head as the guarantor, and sign an IOU. In this way, if you default at that time, I can find an intermediary to prove that you really owe me money, But there are two problems: 1. What if the village head finds out that his long lost son colludes with him to cheat you on money? 2. What if the middleman dies on the spot the next day! This is about trust and security. If the method of
blockchain is to provide you with the certificate of the whole village (distributed), so that everyone knows about it and the other party can't default on it. Second, even if a small number of people or village heads deny (some nodes commit crimes) that they have lost the IOU or tampered with the content, there will still be others to make the basis
above, explain the two problems of building owners: 1. Decentralization, because the account book records are not centralized in the hands of each participant, and you will get paid if you save and keep accounts. 2. Since I can get rewards by saving and keeping accounts, can I just keep accounts instead of storing them? If you have a mining pool, you can keep accounts for it and store it for you. In this way, you can still get good rewards. There are only a few mining pools in the world, so they are centralized
6. The decentralization of blockchain refers to the form of social relations and content generation formed in the process of blockchain development. It is a new network content proction process relative to "centralization"
blockchain is an important concept of bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains the information of a batch of bitcoin network transactions, which is used to verify the effectiveness of its information (anti-counterfeiting) and generate the next block
blockchain is unified in the whole network, so it is logically centralized. From the perspective of architecture, blockchain is based on peer-to-peer network, so it is decentralized. From the perspective of governance, blockchain makes it difficult for a few people to control the whole system through consensus algorithm, so it is decentralized
extended data:
characteristics of blockchain Decentralization:
decentralization, not without the center, but by the node to freely choose the center, freely determine the center. In short, centralization means that the center determines the node. The node must depend on the center, and the node cannot survive without the center
in a decentralized system, anyone is a node, and anyone can be a center. Any center is not permanent, but phased, and no center is mandatory for nodes
with the diversification of network service forms, the decentralized network model becomes more and more clear and possible. After the rise of Web2.0, the services provided by Wikipedia, Flickr, blogger and other network service providers are decentralized. Any participant can submit content, and Internet users can create or contribute content together

7. Jiangsu Rongze e-license blockchain platform and ZTE Shenzhen's shared government platform are excellent platforms. Tencent, Jingdong and ant have also made efforts in this direction, and there is no specific platform to be implemented.
8. Litecoin is a kind of network currency based on "peer-to-peer" technology, which can help users pay to anyone in the world immediately. At present, lightcoin is the second
virtual currency after bitcoin in global circulation market value. The legends of bitcoin, Wright silver, infinite copper and pennies aluminum (Internet) are popular in the circle. The popular digital currencies in 2013 include bitcoin, Leyte coin, zeta coin, pennies (Internet), invisible gold bar, red coin, pole coin, BBQ coin and prime currency. At present, hundreds of digital currencies are issued all over the world. Litecoin is inspired by bitcoin (BTC), and has the same implementation principle in technology. The creation and transfer of litecoin is based on an open source encryption protocol, which is not managed by any central authority. Litecoin aims to improve bitcoin. Compared with bitcoin, litecoin has three significant differences. First, the liteoin network can process a block every 2.5 minutes (instead of 10 minutes), so it can provide faster transaction confirmation. Second, the output of litecoin network is expected to be 84 million litecoin, which is four times the amount of currency issued by bitcoin network. Thirdly, the scrypt encryption algorithm first proposed by Colin Percival is used in litcoin's workload proof algorithm, which makes it easier to mine litcoin on ordinary computer than bitcoin. Each litecain is divided into 100000000 smaller units, defined by eight decimal places. Lightcoin needs to be generated by "miner's mining". Mining is done by hashing with computer graphics card. If the value of "mine burst" is calculated, the system will reward 50 lightcoin at one time. At present, the
computing power of lightcoin is growing rapidly, and miner can't dig mine through several computers. Therefore, it needs to be added to the mine pool, which collects all the computing power, It is estimated that the probability of calculating the "blasting" value is higher. At present, the well-known
ore pools abroad include: wemineltc, coinotron, etc
9. This is related to settings and has nothing to do with the system. I'm win764 bit and still use it. I haven't used the function of good farming. I think there are two common mistakes about playing monster. The first one is the setting of shortcut key for selecting monster. The default of the software is ATL + tab, which is the default shortcut key of the system, but it is estimated that few people use this shortcut key. I set the game is F11 choose strange, but hang in no change will appear can't choose strange, can't play strange stand. The second problem may be the mode. If I remember correctly, he has many modes, such as ares mode and single brush mode. Characters are not strange. Generally, for the sake of efficiency, I choose the speed mode. As for mining, the first possibility is that you are moving the mouse. Mining is different from fighting monsters. When fighting monsters, you don't need to use the mouse to run in the background. Mining stones need to use the mouse, which is not really running in the background. Although they can operate in the background when looking for minerals, they need to control the mouse when mining, so if you are moving the mouse, they can't mine. The second possibility is that there are monsters nearby. The button sprite is identified according to the color of the picture. When monsters are dense and the red dots of monsters cover the mining spots on the small map, it is impossible to collect them. I'm tired of playing by hand. I hope you can adopt it
10. Bitcoin falls into & lt; Tug of war;, I don't think bitcoin will be enough in the future; Become a regular & quot
Bitcoin is decentralized, no one can control it, and no country can manage it
bitcoin, as an emerging instry, has attracted many people's attention. If bitcoin can be bought in the whole few years, it must have made a lot of money now. The crazy money making effect of bitcoin has attracted more and more people's attention. Bitcoin falls into & lt; Tug of war;, I don't think bitcoin will be enough in the future; Become a regular;, There is no way to manage bitcoin decentralised countries, and no way to manage bitcoin decentralised countries; Become a regular;, Bitcoin is not affected by monetary policy, and the state has no way to regulate, which affects the development of the country. Bitcoin has no sovereignty; Become a regular & quot; It will challenge the national formal currency
Third, bitcoin is not affected by the national monetary control, which is not concive to the development of the country. The country manages or controls its economy through monetary policy adjustment, but bitcoin is not affected by these factors, which is why it can't & lt; Become a regular & quot; The reason for that
