What is bitcoin and why dig it

1.

bitcoin is the first distributed virtual currency

to mine bitcoin, you can download the special bitcoin computing tools, register various cooperation websites, fill the registered user name and password into the computing program, and then click the operation to officially start. After completing the installation of bitcoin client, you can directly obtain a bitcoin address. When others pay, you only need to paste the address to others, and you can pay through the same client

after installing the bitcoin client, it will assign a private key and a public key. You need to back up the wallet data containing your private key to ensure that your property is not lost. Unfortunately, if the hard disk is completely formatted, personal bitcoin will be completely lost

extended information:

as a virtual commodity, bitcoin itself has no national boundaries, and its operation mode is a "decentralized" monetary system, which is very convenient for one-time large transaction. Bitcoin is traded through the network, and the owner's identity is only in the form of a set of encrypted computer code

in the operation, input a digital address directly, click the mouse a few times, and wait for the confirmation of the transaction to complete the transaction. The network can only record which address a bitcoin was g up from and how it was transferred

however, the identity of the owners of these addresses can not be verified, which is just like when money goes to an ownerless bank account, the relevant transactions can easily be invisible from the perspective of government supervision, and it is difficult to be tracked or intercepted. In addition, bitcoin can evade the scrutiny of exchange control institutions required by normal cross-border remittance, and the transaction records will not be recorded by banks and other parties

naturally, the problem of reporting to relevant departments after the transaction exceeds a certain amount is avoided. Buy bitcoin with domestic currency, sell it on foreign trading platforms, and withdraw it in US dollars. Asset transfer can be completed in a few minutes

it is not difficult to open an overseas bank account related to bitcoin for foreign exchange, and the conversion is very convenient. Because of these characteristics, bitcoin has been chosen by criminal organizations

2. 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

mining bitcoin is also called mining. Starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique

in the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million

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, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods

extended data:

shortcomings

first, the vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities

Second, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed

Thirdly, the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading

Fourthly, the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless

5. Mining is a process of consuming computing resources to process transactions, ensuring network security and keeping everyone's information synchronized in the network. It can be understood as the data center of bitcoin. The difference lies in its completely decentralized design. Miners operate all over the world, and no one can control the network. This process is called "mining" because it is similar to gold panning, because it is also a temporary mechanism for issuing new bitcoin. However, unlike gold panning, bitcoin mining provides rewards for services that ensure the safe operation of payment networks. After the last bitcoin, mining is still necessary

mining is a proof mechanism.

6. The actions in bitcoin can be regarded as the use of graphics card to do continuous general computing, and the computational complexity is relatively low and quite repetitive. The stream processor used by graphics card is just suitable for such an algorithm. It's like constantly solving equations. The graphics card is 2000 middle school students, while the CPU is 8 math doctors. Although the mathematical knowledge of the doctor of mathematics is far more than that of the middle school students, the speed of solving medium-sized equations such as virtual currency is certainly not as fast as that of 2000 middle school students
therefore, we used graphics cards to mine virtual currency at the beginning. After that, someone developed a specific algorithm to make the stream processor of the graphics card greatly strengthen the virtual currency solution, which is the origin of the mining machine
the transmission of knowledge is driven by life

7. The bitcoin system adjusts the difficulty coefficient to ensure that bitcoin will not be g up too quickly
every 10 minutes, the miners of the whole network work together to solve a problem and compete for bookkeeping rights and bitcoin rewards. If the computing power of the whole network continues to grow, bitcoin will soon be g out
in order to ensure the stability of bitcoin and dig out a block in about 10 minutes, Nakamoto Tsung designed that the difficulty of getting bitcoin from miners' mining should be dynamically adjusted every 2016 blocks (about 2 weeks). After the adjustment, the expected time for each block to be generated is 10 minutes
the current difficulty coefficient is about 480ph / s, which is about 68 billion times that of Genesis block. In other words, with the current computing power, the miners in the whole network need to go through about 300 trillion hash operations to find a qualified answer and generate a new block.

8. According to the relevant literature of bitcoin, in 2140, 2100 bitcoins will be proced and will not grow. According to the principle of bitcoin, after 33 halving periods, the mining output of each block will reach 0.58 Cong, less than the minimum unit of one Cong. The interval of each half rection is 210000 blocks, and the total proction time (2140 years) given in the above literature is calculated from the proction time of each block of 10 minutes 210000 * 10 / 60 / 24 / 365 = 3.9954 * 33 = 132 years. Since 2008, 132 years later, it is 2140 years)
however, it is an ideal state that the "proction time of each block is 10 minutes" used in the above calculation method, which is only true when the computing power and difficulty of the whole network do not change. Looking at the bitcoin blockchain, it is not difficult to find that bitcoin's whole network computing power has been growing for a long time, and the difficulty of mining has also increased. Therefore, it is not difficult to find out that the above calculation is not tenable and there is a huge error.

9. Bitcoin is more and more difficult to dig in the future. Now ordinary computers can't dig a coin a year, so it's very difficult to dig out. In fact, it doesn't matter how much bitcoin has not been g. The minimum unit of bitcoin can be one in 100 million, so there's no need to worry about the quantity.
