Does bitcoin mining help solve real problems

1. At present, only a few algorithms of virtual currency are meaningful, such as XPM (prime currency, used to solve prime numbers), GRC (Greider currency, used for scientific operation), etc. I have been using CPU to dig XPM, although my income is limited. In fact, these currencies also have the excellent properties of bitcoin, but they are not favored by most virtual currency lovers. The price is very low, which is really distressing.

2. In order to know what mining is calculating, we must first know the essence of bitcoin and its proction process. Bitcoin is a network-based electronic currency, which is actually a string of codes of the Internet, calculated by algorithms. Mining is the process of completing the algorithm and the only way to proce bitcoin. And because of the algorithm, there are only 21 million bitcoins
1. Mining can not only proce bitcoin, but also guarantee transaction information
similarly, a mathematical system contains 21 million mathematical problems, so we need to constantly seek the special solution of each mathematical problem through a huge amount of calculation. In addition, the special solution is unique
mining can not only increase the supply of bitcoin money, but also protect the security of bitcoin transactions and prevent fraulent transactions. In terms of process, bitcoin network is a point-to-point payment system, and anyone can trade through the transaction program
in order to ensure that the transaction process is truthfully recorded, the role of "miner" is required to be responsible for recording bitcoin transaction information. The time interval is 10 minutes. The best recorded transaction records among miners will be packaged and stored in a new block, and the corresponding miners will also receive a certain amount of bitcoin rewards
2. The mining process is extremely complex, which is beyond human power
the specific process is as follows. When a miner listens to the transaction, he will first verify the transaction information. The verified transactions will be recorded by miners and stored in their own database. There may be thousands of miners in the world doing the same thing, but every ten minutes, only one miner has the right to create a new block, so that the transaction information recorded by himself can be recognized and stored permanently
next, miners need to fight for the right to keep accounts. This is a competition of computing power. The core of this competition is to use computers to complete a large number of calculation tasks and find a super difficult random number. This random number is the special solution of the equation mentioned in the first paragraph. The miner who calculates the correct random number first wins. According to the rules of the game, the probability of a miner getting the accounting right is directly proportional to the proportion of his computing power in the total computing power of the whole network. In other words, the probability of finding the random number is equivalent to throwing out 100 million dice, and the total number of dice is less than 150 million. Therefore, mining requires a large number of computers, installation of specific algorithm software, repeated operation day and night, not human
3. Bitcoin mining is actually "villagers' bookkeeping"
maybe some netizens still don't understand, let's take an example. In a village, the villagers often borrow money from each other, even if they write a written document, there is a risk of default. Then, every time there is a loan behavior in the village, we will use the village trumpet to inform everyone that all the villagers (miners) will record all the transaction records in their own account books.

3. Bitcoin uses a graphics card to do an arithmetic, just like we do math problems. It has a rule of that algorithm, and then it uses a graphics card to do the arithmetic. His algorithm will be geometric superposition. So it's hard to find this bitcoin now. There is one of them. Well, you download the roaming browser. He has one called symbiotic coin. That is to say, when you usually surf the Internet, use this browser. You'll generate some virtual coins. Then it can be changed into RMB. I'm not quite clear about his ratio.

4. The pyrolysis and carbonization harmless treatment of animal carcasses by shimai technology is a kind of high temperature harmless treatment technology, which uses high temperature to make the organic components of animal carcasses decompose, release volatile procts and form solid carbonization under the condition of no harm. The role of blockchain in this process is to register the data of processing process to the chain.

5.

Bitcoin is actually a useless string of numbers, but it is recognized as useful, just like diamonds, antiques, calligraphy and paintings, game skin and so on. They can't be eaten or used, but we will recognize their value

"mining" just allows more people to participate in the construction of blockchain network. Is it really good that so many electricity charges are used to "calculate" a series of virtual values? Bitcoin is not a hedge. The price of bitcoin fluctuates greatly. Speculation on bitcoin may become rich overnight or become poor overnight. Bitcoin is not as safe as it claims. In 2014, the world's largest bitcoin trading website, mtgox, was hacked and went bankrupt, and the $467 million worth of bitcoin evaporated instantly. Criminals use it to launder money, evade taxes and so on. It is also quite difficult for the government to investigate. The above personal opinions are welcome to be criticized and corrected. Agree with me, please click like before you go, thank you! Like me, please pay attention to me, thank you again

6. It doesn't make sense. Its existence is not really anything. Not at first. The prototype of blockchain
