Is digital currency easy to dig
mining is a nickname for the exploration method of acquiring bitcoin. Because of its working principle is very similar to mining minerals, so named. In addition, bitcoin explorers who do mining work are also known as miners
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 the bitcoin network will generate a certain amount of bitcoin as a reward to reward the person who gets the answer
extended data:
to be a miner, just "mine" bitcoin and search for 64 bit numbers by computer. By repeatedly decrypting with a computer, it competes with other gold miners to provide the number needed for the bitcoin network
if the computer can successfully create a set of numbers, it will get 25 bitcoins. Bitcoin is decentralized. It needs to create a fixed number of bitcoins per unit of computing time. It can get 25 bitcoins every 10 minutes
by 2140, the upper limit of bitcoin in circulation will reach 21 million. In other words, bitcoin system can be self-sufficient, which can be translated into coding to resist inflation and prevent others from sabotaging< br />

and it uses bitcoin for & quot; Ransom;, This kind of virtual currency is characterized by decentralization, anonymity and can only be used in the digital world, so bitcoin transactions are difficult to track. At the same time, Trojan criminals also hide in anonymous networks. This anonymous network named tor has exposed & quot; Prism project & quot; Snowden, a technical analyst at the U.S. Central Intelligence Agency, once recommended it because it allows users to access anonymously and ensures that the servers they use cannot be traced
