Industrial and commercial bitcoin mine

1. In our country, it is forbidden to open Bitian mine< The central information office of the people's Bank of China, the Ministry of instry and information technology, the State Administration for Instry and commerce, the China Banking Regulatory Commission, the China Securities Regulatory Commission and the China Insurance Regulatory Commission
notice on preventing the risks of token issuance and financing In essence, the so-called "virtual currency" such as ether currency is a kind of unauthorized illegal public financing behavior, which is suspected of illegal selling token tickets, illegal issuing securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal criminal activities. Relevant departments will closely monitor relevant developments, strengthen cooperation with judicial departments and local governments, strictly enforce the law in accordance with the current working mechanism, and resolutely deal with market chaos. If suspected crimes are found, they will be transferred to judicial organs

the token or "virtual currency" used in token issuance financing is not issued by the monetary authority, has no monetary attributes such as legal compensation and compulsion, does not have the same legal status as currency, and cannot and should not be used as currency in the market< (2) no organization or indivial is allowed to engage in the financing activities of token issuance illegally. Organizations and indivials that have completed the token issuance and financing should make arrangements such as refund, reasonably protect the rights and interests of investors, and properly handle risks. Relevant departments will seriously investigate and deal with the activities of token issuance and financing that refuse to stop and the illegal behaviors in completed token issuance and financing projects< 4. Financial institutions and non bank payment institutions shall not carry out business related to token issuance and financing transactions

financial institutions and non bank payment institutions shall not directly or indirectly provide procts or services such as account opening, registration, trading, clearing and settlement for token issuance and financing and "virtual currency", It is not allowed to underwrite insurance business related to token and "virtual currency" or include token and "virtual currency" into the scope of insurance liability. Financial institutions and non bank payment institutions shall report to the relevant departments in a timely manner if they find clues of violation of laws and regulations in token issuance financing transactions< 5. The public should be highly alert to the potential risks in the financing and trading of token issuance

there are multiple risks in the financing and trading of token issuance, including the risk of false assets, the risk of business failure, the risk of investment speculation and so on. Investors should bear the investment risk on their own, and hope that the majority of investors will be wary of being cheated

for all kinds of illegal financial activities carried out by using the name of "currency", the public should strengthen the awareness of risk prevention and identification ability, and timely report relevant illegal clues.

2. Generally, the mine is close to the power station, all in the mountains, and the domestic mines are concentrated in Xinjiang and Yunnan! Those who sell mining machines are all concentrated in Shenzhen

3. Mines are everywhere. You can mine them in your own home, as long as you have equipment. This year, domestic mining has been banned, but some relatively large mines have moved to foreign countries. Now Iceland can be said to be the largest mining area in the world
let's talk about the output. It's not as good as before
with the increase of computing power in the whole network, the proportion of computing power owned by miners in the whole network has decreased
the generation speed of bitcoin is slowing down. When bitcoin was born in 2009, each reward was 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 bounty will be halved to 25. When the total amount reached 15.75 million (5.25 million new output, or 50% of 1050), the bounty was further halved to 12.5. In theory, bitcoin's mining speed has halved in four years
in addition, the equipment investment and electricity charges in the early stage are very expensive
the front runners have already started to drink soup. Want to know the latest information and market of currency circle, exchange. Focus on the mustard circle

If you want to know about the bitcoin mine, you should first understand the related matters of bitcoin Mining:

1. Bitcoin mining

is to use the computer that earns bitcoin, download the special bitcoin computing tools, communicate with the remote server (then, register various cooperation websites, and fill the registered user name and password into the calculation program, Then click the operation to start the operation) to get the corresponding bitcoin

this kind of computer generally has professional mining chips, and works in the way of burning graphics card, which consumes a lot of power

Second, to be a miner is to proce bitcoin with your own computer

in the early client, there was the option of mining, but it has been cancelled. The reason is very simple. With more and more people participating in mining, it may take a few years to dig for 50 coins, so the mining speed is too slow and the cost is high

Third, bitcoin mine with the increase of miners and mining costs, miners generally organize into miners' guild to dig together

so there are professional miners, organized into a professional mining team; They use professional mining machine (computer), professional maintenance personnel, special site, to carry out mining

usually, the mining team composed of special site, professional equipment and professional personnel is called "mine"

bitcoin mine , to put it simply, it is actually equivalent to a server room < br />

5. Erdos, 560 kilometers west of Beijing, is covered with hot waves and sandstorms. The gate is a dividing line, separating the two worlds. Outside the gate is a typical landscape of China's fourth tier Urban Development Zone, while inside the gate is a science fiction scene like the matrix. Eight large factories with blue roofs are juxtaposed. Tens of thousands of "mining machines" are flashing red and green light and roaring in the factory, making digital currency bitcoin for this "mine" day and night. This once the world's largest mine holds about 4% of the computing power (proction capacity) in the bitcoin world. During the peak period, it can dig out more than 100000 bitcoins a year, which is worth more than 3 billion RMB at the price of 30000 RMB in August 2017.
bitcoin was invented by "Zhongben cong" in 2009, Using the computing power of the chip, the boring and repetitive process of constantly "hash collision" in the blocks generated by the bitcoin system to win the bookkeeping right and thus obtain the system reward of bitcoin is vividly called "mining" in the bitcoin instry, and the professional staff engaged in this work are called "in the first few years of bitcoin operation, An ordinary laptop can play the role of "mining". However, the entry of Chinese miners has completely broken the balance of this situation. Relying on professional mining machines designed and made in China, they staged one after another bitcoin world computing power arms race, raising the threshold of "mining" tens of thousands of times

Suppose you understand the blockchain. To put it simply, the blockchain generates a new block every ten minutes to store all the transaction information in the blockchain. This block is equivalent to a network account book, which correctly time stamps all the transactions of the whole network in the past ten minutes. The question is who will build it? The "miner" on the blockchain is to compete for the bookkeeping right of a block in the past ten minutes. The rule of competition is to solve the sha256 problem while correctly bookkeeping. Who can prove that his computer has the fastest computing power can compete for the legal bookkeeping right of the block in the past ten minutes. This is the "mining" process. In the bitcoin blockchain, miners who dig mines can get certain bitcoin rewards. Therefore, miner's more essential function is "bookkeeper"

in his bitcoin white paper, Nakamoto describes in detail the process of establishing the credit system:

Step 1: in order to make the whole network recognize effective, every transaction must be broadcast to each node (node: miner)

Step 2: each miner node should correctly stamp each transaction in the ten minutes and record it in that block

Step 3: each miner node should compete for the legal bookkeeping right of this 10 minute block by solving the sha256 problem, and strive for the reward of 25 bitcoins (50 bitcoins every 10 minutes in the first four years, decreasing by half every four years)

Step 4: if a miner node solves the ten minute sha256 problem, TA will publish all the time stamped transactions recorded in the ten minute block of TA to the whole network, which will be checked by other miner nodes in the whole network

Step 5: other miners in the whole network check the correctness of the block's accounting (because they are also stamping the time stamp for accounting, but they do not compete for the legal block's accounting right, so there is no reward). If there is no error, they will compete for the next block after the legal block, thus forming a single block chain of legal accounting, That is the general ledger of bitcoin payment system - blockchain

generally speaking, each transaction must go through six block confirmations, that is, six ten minute bookkeeping, before it can be recognized as a legal transaction on the blockchain. The following is the accounting format of bitcoin:

so the so-called "bitcoin" is such a billing system: it includes the owner using the private key to make an electronic signature and pay to the next owner, and then the "miners" of the whole network stamp the account to form a blockchain Network)

if you want to learn more about blockchain information, it is recommended that you use Baijia, mustard circle and other popular B circle media. The amount and richness of information are more and better than those on the general network.

Recently, the news about "China quietly ordered the closure of bitcoin mines" spread like wildfire. Some media learned through insiders that the central bank held a closed door meeting to rectify some mines with non-standard electricity consumption

in fact, the rectification and treatment of Mines started last year, especially after the closing of domestic exchanges last year, the relevant regulatory authorities also discussed the issue of mine retention, but the conclusion is that the reasons for closing mines are not sufficient, and the mines have not caused more social problems, and the risk points are not clear, so no specific arrangements have been made. However, all localities have received "window guidance", that is, local enterprises can not participate in digital currency mining

in 2016, China's power generation ranked first in the world, and the total power generation accounted for 25% of the world. In this case, according to common sense, mining power in China is indeed the most abundant, especially with the decline of China's economic growth, the wasted power resources are increasing

the electricity of power stations can not be stored, but if the electricity is converted into digital currency, it can be stored. In fact, if China's surplus power generation can be converted into bitcoin for storage, it should be the most efficient mode of proction and operation. It is equivalent to procing US dollars with electricity. It is a processing export mode with the highest added value

in addition, according to the historical development, most of the power in the future may be consumed by computers. This is a judgment I made, which can be witnessed by our generation. In our daily life, the proportion of electricity consumption will be lower and lower. In the future, mankind will solve all kinds of problems by means of digitization and blockchain, and "mines" will only increase, not decrease. Especially with the development of artificial intelligence, space exploration and other fields, the demand for computing power will increase exponentially

electricity is just a kind of energy, just like a person, the biggest energy consumption is not the limbs, but the brain. The human brain is a 24-hour machine. A thinking person's brain consumes 75% of the liver's stored blood sugar every day, and the oxygen consumption accounts for 20% of the whole body's oxygen consumption. The more the brain thinks, the more glucose the neurons need

When the electric lamp was invented 200 years ago, people thought that the best use of electricity was to light the bulb. Has the final say that what electricity market will be most effective in future? p> No one can see electricity. Up to now, it is difficult for many people to understand the mystery of its existence, but electricity has changed the world. The influence of many virtual things is often greater than that of physical things. What does "digital assets" mean to China and the world? I think it is difficult for many people, including the government, to make clear at this time. What we need to reflect on is that apart from the four great inventions, such as electricity, light, telephone, computer, digital currency and so on, how many of the things that are pushing mankind forward are invented by China

when a phenomenon appears, we must study the background and logic behind it. The future competition can be said to be military competition, economic development competition and financial competition, but it can also be said to be ideological and computational competition. It's easier to close mines than to stop trends

8. Hello, the miner trusteeship depends on the situation
if there are only one or two miners, you can choose to dig at home, rent an empty house in a slightly larger remote point, and use it as a special machine room, so that the miner will not disturb the people and it is convenient for you to visit at any time
if there are dozens or even hundreds of mine machines, it is recommended that you choose mine trusteeship. First, the electricity charge of mine trusteeship will be cheaper than that of indivials, and there are special personnel to take care of mine machines. The inconvenience may be that most of the mines are located in Northwest and southwest provinces, which may not be convenient for you to understand the actual situation, but you can also choose the background software to monitor your own mine machines, The selection of specific mines can be evaluated according to the quotation
if you don't know much about this area before and don't have a miner, you can choose to buy cloud computing power. This kind of miner is only used in a different way. The ownership of the miner doesn't belong to you, but is rented to you

the advantage of the mineral machinery trusteeship lies in the fact that it is not easy to manage; Annual regular electricity subsidies, cheap electricity; 24 hours a day without power cut to dig money; There is operation and maintenance technology in the mine 24 hours on call, problems can be solved immediately; If the power board is broken, it needs to be returned to the factory. The company will have machines to make up the power. However, it is suggested that when you choose a mine, you should consider the quotation of mine management fee and electricity fee
