Mining principle of Nakamoto tsugawa
bitcoin is equivalent to digital gold. As a generally recognized equivalent, gold naturally has monetary properties and has been regarded as a kind of currency since ancient times. Bitcoin was born in 2009 and created by a person named Nakamoto. As the earliest digital currency, it was worthless at the beginning of creation. Until 2017, the highest transaction price of bitcoin exceeded 30000 RMB. The reasons why bitcoin became a valuable digital currency are as follows:
first of all, it is like gold, as a natural mineral, The total amount of bitcoin is limited. Bitcoin can not be over issued according to its own algorithm, so there will be no rapid devaluation of currency e to excessive currency issuance. The number of bitcoin is controlled to no more than 21 million e to the algorithm, so it can not be issued in large quantities, so its value is guaranteed
On January 3, 2009, the first batch of 50 bitcoins were g up on a small server in Finland. On May 21, 2010, the first bitcoin transaction: programmer Laszlo hanyecz bought a $25 pizza coupon with 10000 BTC. This transaction gave birth to the first fair exchange rate of bitcoin.

Satoshi Nakamoto, a self styled Japanese American, is often translated by Japanese media as the founder of bitcoin protocol and its related software bitcoin QT, but his real identity is unknown. In 2008, Nakamoto published a paper called "bitcoin: a peer-to-peer electronic cash system", which describes an electronic currency and its algorithm 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 community. Nakamoto is believed to hold about one million bitcoins. These bitcoins were worth more than $1 billion at the end of 2013since the publication of the paper, the real identity of Nakamoto has long been unknown to the outside world. Julian Assange, founder of WikiLeaks, claims that Nakamoto is a cypherpunk. In addition, some people said that "Nakamoto is an anarchist. His original intention is not to control digital cryptocurrency by a certain government or central bank, but to become a global free flowing currency that is not regulated and controlled by the government."

on November 1, 2008, Nakamoto published a paper entitled "bitcoin: a point-to-point e-cash system" in the cryptography mailing list of "metzdowd. Com". This paper describes in detail how to create a decentralized electronic trading system, and this system does not need to be built on the basis of mutual trust between the two parties. Soon, on January 3, 2009, he developed the first client program to implement the bitcoin algorithm, concted the first "mining" and obtained the first batch of 50 bitcoins. This also marks the formal birth of bitcoin financial system
on December 5, 2010, ring the WikiLeaks leak of US diplomatic cables, the bitcoin community appealed to WikiLeaks to accept bitcoin donations to break the financial blockade. Nakamoto expressed his firm opposition, saying that bitcoin is still in its infancy and cannot afford conflicts and disputes. Seven days later, on December 12, he published his last article in the bitcoin forum, mentioning some minor problems in the latest version of the software. Then he did not show up and e-mail communication was graally terminated
the principle of bitcoin mining is to implement rules made by people and automatically executed by computers
Satoshi Nakamoto, the inventor of bitcoin, has stipulated this rule from the very beginning, and those who participate in bitcoin blockchain must automatically abide by it unconditionally
The content ofrules is generally ,
people who pack the circulation data of bitcoin, arrange it into a fixed size, and then upload it to the blockchain for bitcoin whole network synchronous broadcasting can get 50 bitcoins rewarded by the system
under certain conditions, these rewards will be halved, about once every four years
so how to complete the data packing
the person who wants to complete this action must first have the necessary tools, that is, the software to execute the bitcoin blockchain, and the machine (computer at the beginning) to run the software; Then download and save all the bitcoin transaction data that have been recognized by the whole network. At this time, you become a "node" and a part of protecting the blockchain data
Thenode can only get the priority of the packaged data after running a specific mathematical formula and getting the correct answer. The system will automatically give the reward to the node who gets the priority, who completes the packaging first and then uploads it to the blockchain, and receives and approves it from other nodes
if there is bitcoin service charge in the packaged transaction, the service charge belongs to the node
people think that the process of calculating the mathematical formula and then completing the package to get the reward is just like fishing for gold in the river. It is necessary to discard many wrong answers in order to find the right key to get gold, so people compare this process to mining
so bitcoin mining is not really to dig something, or to use computers to constantly collide and guess. Whoever guesses first wins the reward, that's all

The official website of Tesla USA can use bitcoin to pay. I think this has a significant impact on bitcoin. First of all, bitcoin is a virtual currency.

If you invest all your money in bitcoin, appreciation is the best result, but bitcoin is a virtual currency after all. If no one recognizes its value, So it is worthless, so it is easy to cause everyone's ruin, so we must not blindly follow the unfamiliar things, we must learn to think rationally
in a word, with the development of society, there are many new things, bitcoin is a new thing, now many people regard bitcoin as an investment coin, but bitcoin is a virtual thing after all, so it can not really be used as a value.
