Bitcoin synchronization schematic
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
Bitcoin mining is a process of using computer hardware to do mathematical calculation for bitcoin network to confirm transactions and improve security

Last week, a paragraph about bitcoin became popular:
bitcoin broke through 5800 US dollars (about 38280 yuan) . When it was issued in 2009, 1 US dollar was equivalent to 1300 bitcoins. What is investment? It has increased by 7.54 million times in 8 years. At that time, you spent 38000 yuan to buy some bitcoin. Now you are the richest man in China, surpassing Xu Jiayin, who has 290 billion yuan
but just one week later, on October 20, bitcoin broke through the $6000 mark. Although it fell later, it reached more than $6000 again on October 21, reaching a maximum of $6147. In terms of $6000, bitcoin prices have risen 7.8 million times in eight years
according to cryptocompare, a bitcoin data provider, e to China's strict supervision of cryptocurrency trading, the global share of bitcoin market has been greatly changed. Now, in the total trading volume of the world's bitcoin exchanges, the trading volume of RMB versus bitcoin accounts for about 1.6%

the reporter noted that in the first half of this year, after Japan's legislation recognized bitcoin as a legal payment method, bitcoin's trading volume in Japan surged, and Japanese regulatory authorities have issued certificates to 11 cryptocurrency exchanges. About 58% of bitcoin trading currently takes place in the Japanese market, and nearly a third of yen to bitcoin trading takes place on the bitflyer exchange in Tokyo. In addition, the U.S. and South Korea markets also account for a large part of global bitcoin transactions - the U.S. dollar and the Korean won account for 27% and 7% of the total bitcoin transactions, respectively< br />
elliptic curve digital signature algorithm is mainly used in the generation process of bitcoin public key and private key, which is the cornerstone of bitcoin system. SHA-256 hash algorithm is mainly used in the workload proof mechanism of bitcoin
the principle of bitcoin generation is the special solution generated by complex operation, and mining is the process of finding the special solution. However, the total number of bitcoin is only 21 million, and with the continuous mining of bitcoin, the more difficult it will be to proce bitcoin, and the cost of acquiring bitcoin may be higher than the price of bitcoin itself
the bitcoin block consists of a block header and the transaction list contained in the block. The size of the block header is 80 bytes, which is composed of 4-byte version number, 32 byte hash value of the previous block, 32 byte Merkle root hash, 4-byte timestamp (current time), 4-byte current difficulty value and 4-byte random number. A block header with a fixed length of 80 bytes is the input string used to prove the workload of bitcoin. Constantly change the random number in the block header, that is, the value of nonce, and do double sha256 operation on the block header after each change, and compare the result value with the target value of the current network. If it is less than the target value, the problem is solved successfully, and the workload is proved to be complete
the essence of bitcoin is actually the unique solution of a set of equations generated by a bunch of complex algorithms. Bitcoin is the first distributed virtual currency in the world, which has no specific distribution center. The network of bitcoin is composed of all users, because there is no center to ensure the security of data.
the principle of bitcoin and dogcoin is that different types of mining options only use different software. Does the mining of virtual currency sound much more complicated than the mining in the general sense? In fact, it is not difficult to understand. The simple meaning of virtual currency mining is to let the graphics card carry out mathematical operations and allocate virtual currency according to the percentage of the amount of calculation. How does virtual currency survive in financial market? Since the birth of digital currency, there are several elements supporting its ecological chain, and they can not carry out mining transactions and payments. The way to obtain virtual currency is also inseparable from mining
any store trading with cryptocurrency does not need to pay taxes, nor does it need a lot of capital management fees. The international circulation is very convenient, and it is a very popular currency transaction mode for people and merchants all over the world. Without the control of the central bank, the quantity is limited and can completely resist the pressure of inflation. So as to maintain and increase the value of the common people's wealth
