Internet mining
In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining
the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig
another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful
extended data
currency characteristics of bitcoin
1, decentralized
bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom
2, bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3, exclusive ownership
controlling bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the user himself
4, low transaction cost
bitcoin can be remitted free of charge, but in the end, about 1 bitfen transaction fee will be charged for each transaction to ensure faster transaction execution
5, no hidden cost
as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6, cross platform mining
users can explore the computing power of different hardware on many platforms
Online mining is real, that is, traffic mining
mining refers to the use of bitcoin mining machine to obtain bitcoin, that is, the computer used to earn bitcoin. If you can get bitcoin, you can make money this kind of computer generally has professional mining chips and works by installing a large number of graphics cards, which consumes a lot of power. The computer downloads the mining software and then runs a specific algorithm to get the corresponding bitcoin after communicating with the remote server
precautions:
1. It's better to use DIY mining machine, from purchasing accessories to assembly, and then to mining software, to learn, focus, practice and graally understand the blockchain
Mining is actually a fixed investment process: regardless of the currency price, a certain amount of positions will be increased every day3. The bitcoin wallet used to store bitcoin uses military level encryption, which makes it impossible for hackers to steal easily. Bitcoin wallet also allows users to set two passwords, a public account password and a private password. The user of public account password is to let the user receive bitcoin. If users want to withdraw or transfer bitcoin from their accounts, they need to use a private password
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
this is a kind of virtual currency, which fluctuates
some people run the so-called mining program to "dig" bitcoin in their spare time and sell it when they get it. Some of them operate as companies and invest a lot of manpower and material resources in mining. It's hard to tell the profit and loss
bitcoin is not as easy to get as it used to be.
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
. The bitcoin system ensures that bitcoin will not be g out too quickly by adjusting the difficulty coefficient. Every 10 minutes, the whole network is absent from work to jointly calculate a difficult problem, compete for bookkeeping rights and bitcoin rewards. If the computing power of the whole network continues to grow, bitcoin will be g out soon. In order to ensure that bitcoin can be g out in about 10 minutes, Nakamoto designs the difficulty of mining for bitcoin, Every 2016 blocks (about 2 weeks) are dynamically adjusted, so that the difficulty after adjustment makes the expected time for each block to be generated 10 minutes. Now the difficulty coefficient is about 480ph / S (Note: September 2017), which is about 68 billion times that of Genesis block. In other words, with the current computing power, the miners in the whole network need to go through about 300 trillion hash operations to find a qualified answer, Generate a new block
. Compared with point-to-point trading, mining and other purchases on the trading platform are the most popular ways to obtain blockchain assets, that is, floor trading. Floor trading of blockchain assets is similar to stock trading. The platform can help you match up, and you don't need to know who your trading partner is. Your trading partner may be one person or many people, Whether it's buying or selling, the trading platform will record the hanging order price of everyone. The buyer and the seller can obtain the latest transaction price through the real-time order. At the same time, the trading platform will summarize the historical transaction price and volume into a K-line chart, which is convenient for investors to analyze the market trend. For example, the UTOR market is the mainstream trading platform in the world.
