Mining acceptance

1. In fact, the mining calculation of bitcoin is to do math problems together. The problem stem is the transaction that needs to be recorded. By doing the problem, everyone grabs the bookkeeping right, and the miners can get system rewards and transaction fees
the feature of sha256 algorithm used in bitcoin is that it's easy to verify the known answers correctly, but it's very troublesome to get the answers, and you need to try them one by one. The miner who got the answer first was recognized by everyone as having snatched the right to keep accounts, and the reward was given to him. Let's continue to grab the bookkeeping right of the next question
simply speaking, the significance of these calculations only lies in ensuring the stability and security of the whole system, and has no more significance. It is not comprehensive to regard bitcoin as a by-proct of computing. The generation and issuance of bitcoin, all the transactions and circulation in the bitcoin chain, and the stability of the bitcoin system are all the purposes of computing. Of course, in addition to maintaining the system, it does not proce other value and procts. This is also a black spot where bitcoin is accused of not being environmentally friendly and wasting resources
in general, bitcoin, as a milestone blockchain digital currency, comes from the huge value of a large amount of computing power investment and user trust. There is no doubt about that.

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million

3. It's a very simple method. You can directly input your electricity bill with the small tools of the mine pool, such as the coin printing mine pool, and you can see the corresponding daily output of each model and the income converted into RMB. At the same time, you can see the market prices of different models of machines on today's miner's official website, and you can calculate the return cycle.

4. All kinds of digital currencies on the market are essentially a game of playing drums and spreading money, plus a pyramid scheme! It's all scams carefully packaged by swindlers! It's just a tool for cutting leeks.

5. 1. Digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy

2. Digital currency is a kind of unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form
