Definition of bitcoin in China
{rrrrrrr}
bitcoin (BTC) is a digital currency with a total amount of 21 million. It has the characteristics of decentralization, globalization and anonymity, just like the Internet. It means that transferring bitcoin to the other end of the earth is as simple as sending e-mail, low-cost and unlimited. Bitcoin is also used in cross-border trade, payment, remittance and other fields
the liquidity and limitation of bitcoin determine that bitcoin can act as a monetary function equivalent to general equivalent, or as a measure of money, but this measure is not a physical measure like gold, but a digital proct
related concepts:
1. Address
the address of bitcoin world looks like this. The address itself is just a string of codes, just like your bank account number 321 million 3288372, which is used to mark an account. Everyone can have countless addresses. The address is public
2. The bank records how much money there is in the bank account
the amount of money in the bitcoin address is recorded by the whole bitcoin network. Each complete bitcoin data will record how many bitcoins are stored in this address
each node participating in the bitcoin network can save a complete of bitcoin data, and everyone has a backup on hand to prevent counterfeiting
3. The key (private key)
the key is another string of characters you only know. The key is used to operate the money in the bitcoin address. Key and address are the relationship between a key and a lock. Each address has only one password, and each password also operates a bitcoin address
with the key, you can control the money in the bitcoin address and pay to anyone. The key should be absolutely safe. The lost or deleted key can never be found, and the money in the corresponding bitcoin address can never be used
the key needs to be kept absolutely secret. Anyone who knows the key can steal all your bitcoin
4. Wallet
the transaction process of bitcoin will involve a lot of complex calculations. In order to simplify the operation, we have made wallets. The wallet has client software on the computer, and also has an online web version. The function of the wallet is to pay with a little touch, and the complicated calculation behind it is left to the wallet to complete
5. Security
if you use the computer client software, you can recommend multibit or bitcoin QT. Both are official software recommendations for the bitcoin community. The installation of these two softwares must be downloaded directly from the official website, and the check code must be checked before and after downloading. This is to prevent someone from tampering with wallet software and stealing keys
6. mining
about every 10 minutes, some new bitcoin will appear in the bitcoin network, which can be imagined as throwing money in the sky. Whose pocket these scattered money fall into mainly depends on whose computer calculates fast. The faster you calculate, the more likely you are to find the money. Mining is to use the computer to calculate, to pick up the money< br />
Bitcoin, English name bitcoin, is a digital currency based on blockchain technology, which is composed of a series of computer-generated complex codes. Like RMB's ￥ and US dollar's $, bitcoin has its own symbol, the "B" in the figure below
The inventor of 
bitcoin is Nakamoto. Satoshi Nakamoto is the creator of bitcoin protocol and its related software bitcoin QT. In 2008, he published a paper called "bitcoin: a peer-to-peer electronic cash system", describing an electronic currency and its algorithm that he called "bitcoin"
In 2009, he released the first bitcoin software and officially launched the bitcoin financial system In 2010, he graally faded out and handed over the project to other members of the bitcoin communityNakamoto is believed to hold about one million bitcoins. If the price of each bitcoin was $2W, it was worth $20 billion at one time. So far, his true identity is still unknown to the outside world, that is to say, no one knows who Nakamoto is
bitcoin appeared after the global financial crisis in 2008. In fact, before that, many people have tried electronic currency, digital currency and virtual currency, but they have not succeeded. There are not only technical reasons, but also social environment and economic background reasons. To some extent, it was the 2008 financial crisis that gave birth to bitcoin
BTC CNY LTC means RMB transaction between bitcoin and Leyte, which supports the free exchange among bitcoin, Leyte and RMB.
The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, 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
Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of money circulationbitcoin: 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, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods
bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system. Bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network will get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer
users can buy bitcoin, and at the same time, they can use computers to "mine" bitcoin according to a large number of calculations. When users "mine" bitcoin, they need to search for 64 bit numbers by computer, and then compete with other gold diggers by repeatedly solving riddles to provide the required numbers for bitcoin network. If the user's computer successfully creates a set of numbers
bitcoin is e-cash similar to e-mail. Both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free
