Decentralization is the biggest selling point of bitcoin

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. 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

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

(3) disadvantages:

< UL >

the vulnerability of trading platform

transaction confirmation takes a long time

the price fluctuates greatly

the public did not understand the principle, and the traditional financial practitioners resisted

6. Bitcoin is a virtual cryptocurrency based on decentralization, peer-to-peer network, consensus initiative, open source, and blockchain as the underlying technology. It was proposed by Nakamoto in 2008 and born in 2009
bitcoin does not have a centralized issuer. It is generated by the calculation of network nodes. It can be bought and sold on any computer connected to the Internet, and has a strong scarcity
Decentralization: bitcoin is the first distributed virtual currency. The whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom

Global Circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin

exclusive ownership: private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself

low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution

no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay

cross platform Mining: users can explore the computing power of different hardware on many platforms

The original intention of Nakamoto's design of bitcoin is to build a point-to-point trading network that is decentralized, transaction information can not be tampered with, and the total amount of money is constant, so as to solve the problems of excessive issuance of legal currency and inflation

this is the value of bitcoin's initial design, to keep the purchasing power of money

But later, the development of bitcoin went against Nakamoto's idea. In the past nine years, the price of bitcoin soared by millions of times, creating countless myths of sudden wealth and driving another instry mining

the value of bitcoin has become a tool for "sudden wealth". More and more people join the bitcoin network, hoping to achieve financial freedom. Digital cryptocurrencies such as bitcoin have become investment procts, like diamonds or gold

by purchasing bitcoin, people can achieve the purpose of wealth appreciation and asset preservation in many troubled areas. At the same time, many people make use of the fluctuation of bitcoin price to speculate, such as moving bricks, making bands and so on

another important value of bitcoin can not be ignored is blockchain, the underlying technology of bitcoin. Because of the popularity of bitcoin, many companies and indivials begin to pay attention to blockchain, and constantly try to use blockchain technology to change the existing business and create new value. It is with the help of bitcoin that blockchain has achieved such rapid development

bitcoin is also a great social experiment for all mankind, which promotes the reform of the financial instry and gives many original things a new perspective

8. Bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, 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. 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.

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. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million
bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items
