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. Nakamoto is the first person to discover bitcoin. Bitcoin is not issued by any institution, and the total amount is only 21 million yuan. The transaction of bitcoin needs the consent of 6 people!
3. 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.
4. This is not necessarily true. After all, it is a digital cryptocurrency, each of which is separate and not stored on the website.
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. For more technical overview of betterhash protocol currently under development, it should be enough to see the speech of Matt Corallo. It is unnecessary to understand the problem of reprinting the theory of self fighting game network in this paper, because Conceptually speaking, betterhash is better objectively, and it does not need a complete code implementation to understand how important it is.
7. 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

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. In fact, in the final analysis, it is distributed accounting. The idea is different from the current centralized operation system. This can be realized, and there is no problem.
10. Bitcoin was born on January 3, 2009, which has a history of 10 years. The value of bitcoin has soared from zero to US $19850, the highest point in 2017. And most people have been concerned about cryptocurrency and bitcoin since then. Before that, most people would think that bitcoin was just an "internet currency", similar to q-coin
bitcoin is the leading cryptocurrency, which has been the absolute consensus in this instry. Looking back over the past few years, among the top ten cryptocurrencies in terms of market value, only bitcoin has always been the first, and the remaining counterfeit currencies are all in the past
