1. Bitcoin is a network virtual currency. Bitcoin network generates new Bitcoin through "mining". The so -called "mining" is essentially using a computer to solve a complex mathematical problem to ensure the consistency of the Bitcoin network distributed bookkeeping system. Assuming that the mining computing power is 100Mhash/s, and the total computing power per day is 4000GHash/s, then 3,600 bitcoins can be dug out every 24 hours.
2. China's computing power has accounted for more than 75%of the world, which means that 75%of Bitcoin in the world is Made in China. So how long does it take to dig a bitcoin?
3. The former Bitcoin was very good to "dig", and ordinary computer CPUs can be completed. Just download the software to automatically "solve the problem". However, as the price of currency rises, there are more and more people who want to "solve problems", and the difficulty of mining is becoming more and more difficult. Now digging a bitcoin that needs to be consumed by ordinary people is unable to bear it at all, so don't think about ordinary computers.
4. Industry insiders said that in 2014, 100 Bitcoin output of 500,000 yuan per day, the cost of electricity costs only 5,000 yuan each. But now, the same cost has doubled, and the cost of each bitcoin electricity cost is as high as 10,000 yuan.
5. In the mechanism of Bitcoin, mining rewards are decreasing. At the beginning of Bitcoin, each page of the ledger was remembered, and the miner could get 50 Bitcoin. Later, a page was rewarded for 25, which decreased in turn. Just like digging gold, it started to dig a lot at the beginning, and later became less and less. At the time of a new reward at half a reward, it is called halving Bitcoin output.
6. Suppose the mining computing power is 100MHash/s. In 2014, the total computing power of 4000GHash/s in 2014 was dug 3,600 bitcoins every 24 hours.
7. Now, we can understand the difficulty of digging Bitcoin in this way, which is equivalent to the number of 100 million dice throwing a number of less than 100 million. At this time, the 10050 50 50 is a hash value. The process of throwing the dice is called a hash collision, and the unit of mining power is how many hash collision per second.
8. At present, the computing power of Bitcoin reaches 2.36 trillion has has a hash collision per second, which is equivalent to more than 20,000 50 -meter -long standard swimming pool. But even such a large computing power, it takes about 10 minutes to collide with a hash value that meets the requirements.
9.2012 Bitcoin entered the number of output. In July 2016, the second output of Bitcoin was halved. At present, the reward received by the ledger for one page is 12.5 Bitcoin. The next halving will occur around 2020, and the total number of Bitcoin will not increase in 2040, and the total amount will be 21 million.
