How is bitcoin realized

1.

The remitter will pay bitcoin directly to the other party according to the address of the payee through the computer or smart phone

after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed

the bitcoin peer-to-peer network stores all transaction history in the "blockchain". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. In fact, blockchain is a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history

extended data

users can buy bitcoin, and at the same time, they can "mine" bitcoin by using computers to perform a large number of calculations according to the algorithm. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins

from 2012 to 2014, bitcoin swept the world, and graally formed the "virtual currency" instry chain represented by bitcoin. This is a change in the financial instry and a new proct of the combination of the financial instry and the Internet. It represents a financial milestone in the new era and marks a new chapter in the history of the Internet. Bitcoin fund is one of the derivative procts represented by bitcoin in the era of "virtual currency"

according to the relevant news reports of Fuhui China, bitcoin fund will be open for operation in the autumn of 2014. Fuhui bitcoin fund, as the world's first operation mode of mutual benefit and win-win with financial management mode, is original and full of temptation and challenge

2. mining is definitely the first professional mining machine. Many new children's shoes will choose to use the graphics card to mine, but the graphics card mining is just like doing a professional job with the "magic oil", but the efficiency is certainly not high. To dig bitcoin, we should pay attention to the following points: first, computing power (i.e. mining speed), second, power consumption, and third, stable performance. Computing power, bitcoin mining is faster than problem-solving speed, so it is self-evident that speed is more important; Power consumption is directly related to efficiency, that is, the issue of cost expenditure; The stability of performance mainly depends on the stability of calculation force when the working frequency is constant. Just think about it, no one wants the miner to lose its computing power every so often, or even break down. After all, it's all money ~
the general computing power of the graphics card is a few gigabytes, while the professional miner chip is as high as several thousand gigabytes. Take bm1387, the chip with the lowest power consumption in the world, as an example, the S9's computing power is as high as 14T, the power consumption on the wall is only 1400W, and the rated computing power reaches 13.5 Th / s ± 1 J / GH + 12% (wall, AC / DC 93% efficiency, 25 ° Rated voltage: 11.6 ~ 13.0v, in addition, in the case of non independent power supply, three power calculation boards can be connected to different power supply respectively, but each power calculation board can not be connected to multiple power supply, and ensure that the power calculation board is finally powered on
among the mining machines, ant mining machine is my favorite. At the same time, based on the average investment cost of bitcoin in the early stage, ant S9 can basically recover the capital in about five months, and the income in the later stage is immeasurable.

3. 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 money 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
on February 16, 2021, the price of bitcoin exceeded $50000. On February 20, 2021, the total market value of bitcoin broke through the $1 trillion mark. On February 22, 2021, the price of bitcoin exceeded $58000 per coin. On the evening of February 22, 2021, bitcoin's decline widened e to the counterattack of short selling funds. It once fell below US $48000 / piece, with a decline of nearly 17%. Subsequently, long funds quickly began to bottom, in half an hour, bitcoin fell from 17% to 6%. According to coingecko, as of 0:00 on February 23, Beijing time, bitcoin was at US $52878.42 per coin, down 9% in 24 hours

warm tips: ① according to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have the monetary attributes of legal compensation and mandatory, is not a real currency, does not have the same legal status as currency, and cannot and should not be used as currency in the market, Citizens' investment and transaction of virtual currency are not protected by law
② the above explanation is for reference only. Before investing, it is suggested that you first understand the risks existing in the project, and understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistaking into the capital market
③ investors should not use such information to replace their independent judgment or make decisions only based on such information, which does not constitute any investment operation

4. Sell out, in the exchange, there is a buyer, withdraw cash operation is to first transfer the currency account to the legal currency account, and then sell!

5. We have to find an exchange, but the exchanges are all privately established abroad, and bitcoin trading is illegal in China.

6. Hello, if it's bitcoin purchased by the exchange, find the relevant withdrawal on the login page, enter your bitcoin address, fill in the amount of bitcoin withdrawn, submit the application, and wait until it's approved. Finally, check whether it's received in the bitcoin's block browser.

7. Hello
at present, you can only trade in the outfield. Depending on whether your currency is exchanged on the platform or in your wallet, you can directly check whether there is the function of exchange withdrawal on the platform. If not, you can withdraw it to your wallet first
Second, if the currency is in your wallet, you can directly apply to the outfield organizations like btccas to convert it into RMB. At present, these are the two most convenient ways
thank you

8. Bitcoin is now mainly realized through online transactions
