Is bitcoin really decentralized

1. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. 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.

2.

Bitcoin is just a game. If it is promoted as a tool to get rich, it can be regarded as a fraud. Just like the currency in other online games, the only difference is that bitcoin has been standardized since the game was first formulated. It can't be issued indiscriminately, so it can keep its value better than other virtual game props. It is equivalent to the online collection. Bitcoin is a prop in the game, and its value is reflected in the recognition of bitcoin by players: more people play, the value of props in the game is higher; The risk is that he is not the only game, and his algorithm is not the only one. Maybe someone will be able to make other special coins soon. All you need to do is promote the game and sell your props. As for money, bitcoin does not have the basic attributes of money, such as unfair initial distribution and insecure circulation. Money needs to be maintained by the state machine

1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals

2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency

3. On May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! Nearly 74 countries in the world have been seriously attacked

4. From August 1, 2017, global bitcoin trading platform will suspend recharge and withdrawal services. Bitcoin China digital asset trading platform will stop new user registration on September 14, and all trading businesses will be stopped on September 30

3. 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.

4. 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.

5. This is not necessarily true. After all, it is a digital cryptocurrency, each of which is separate and not stored on the website.

6. 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

7. The design of "decentralization" determines that the "centralized" government cannot touch bitcoin
the emergence, development, amendment, circulation and extinction of bitcoin do not depend on the government, so "whether the government allows" has nothing to do with "whether bitcoin exists"
for example, the birth, development and extinction of the solar system do not need the permission of the government
if bitcoin is exchanged with the government controlled "legal tender" (such as US dollar), the government can influence the performance of bitcoin by controlling the legal tender
if the recognition of such assets reaches the bottom line of% 35 in 2019, the world pattern will be more reasonable, transparent and open

how should we deal with the coming risks- Buy bitcoin quickly to deal with the risk of "no bitcoin".

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
