Bitcoin miners dig the main chain

1. mining is actually competing for the right to pack in the block
as tens of thousands of miners compete for the right to pack, the probability of a single miner seizing the right to pack is very small, and the output is very unstable. It is possible to grab the right once an hour or not once a year
in order to stabilize the mining output, miners often choose to join the mining pool. The mining pool integrates the computing power of a large number of miners and occupies a certain share in the total computing power of the whole network, so as to obtain a more stable mining output. After charging 2% ~ 4% of the pool handling charge, the output is distributed to the miners according to the miners' computing power
it's just like that it's hard for one person to win the lottery, so the mine pool organizes many people to buy the lottery together, and after winning the lottery, they are distributed to everyone according to the amount of contribution.

bitcoin is actually a virtual currency. When bitcoin first appeared, if you want to get bitcoin, you have to get bitcoin through mining. Therefore, bitcoin mining appeared. But bitcoin mining is more and more difficult, so it is very difficult to get bitcoin now

so now many people use Haru miner digs Ethereum, Monroe and other virtual coins. Most importantly, BTC can be directly equivalent in the end

1. First of all, connect the network cable, plug the network cable into the network cable interface of the mining machine, and remember to plug it tightly. Only when the miner is connected to the Internet, there is no limit to the broadband

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

4. Hanging order is the number of orders waiting to be bought and sold behind the five trading prices transmitted from the exchange ring the market trading period. Together with five trading prices, these ten data constitute the most original public data in the whole trading system

I wish you progress in your study! Hope to adopt Hee hee

6. Can you make money by buying a miner? Dream about it. Simply put, an Avalon 50g miner can dig a BTC every day for 70000 RMB a month ago, but it can only dig 0.8% less than half a month ago. Every half a month, the profit will drop by more than 10%. You can make your own equation to see if you can get back the cost
What CCTV has reported twice, do you still expect to make money? Everyone knows that things that make money don't make money
mining companies and consortia are now working on dozens and hundreds of mining equipment. Do you think the personal retail miner can really recover the cost? According to the price can really return the words, the seller is a fool to sell it to you?

Installing bitcoin software is like playing games. Anyone can run software on special hardware and become a bitcoin miner

for example, mining software monitors transaction broadcast through P2P network and performs appropriate tasks to process and confirm these transactions

new transactions need to be included in a block with mathematical workload proof to be confirmed

this kind of proof is difficult to generate because it can only be generated by trying billions of calculations per second. Miners need to run these calculations before their blocks are accepted and rewarded

as more people start mining, the difficulty of finding effective blocks will be automatically increased by the network to ensure that the average time to find blocks is kept at 10 minutes. Therefore, the competition for mining is very fierce, and no indivial miner can control the content contained in the block chain

because it is necessary to recalculate the workload proof of all subsequent blocks. When two blocks are found at the same time, the miner will process the first block received, and once the next block is found, it will be transferred to the longest block chain
