Where does bitcoin's computing power go

1.

The following is the distribution chart of computing power:

the computing power of bitcoin is mainly controlled by some mine owners in the world, and the computing power of retail investors is very small, almost negligible. The computing power of China's mining pool even accounts for more than 80%, and China's voice is increasing

however, many digital currencies no longer need to be mined. Some digital currencies will be directly sent to investors through ICO, and Puyin is one of the representatives, but these digital currencies generally correspond to real assets

2. From cheap electricity to centralized mining, China's resources and environment provide bitcoin miners with many advantages. In recent years, bitcoin miners have used cheap electricity to expand their business in coal rich regions such as Xinjiang and Inner Mongolia, which are home to the founders of some of the world's leading mining companies

with the rising price of bitcoin, more and more people join the bitcoin mining business. Accordingly, mining consumes more and more energy. Obviously, our government is also aware of this

according to the requirements of the document, regulators require local governments to take measures related to electricity price, land use, tax and environmental protection to guide bitcoin miners to withdraw from the business. According to foreign media reports, regulatory authorities are mainly concerned about the money laundering and financial risks involved in the shutdown policy, but excessive power consumption is also a factor that can not be ignored. In principle, bitcoin mining consumes a lot of power because every time a new bitcoin is proced, it needs to solve the complex mathematical problems through the encryption process performed by a high-performance computer. Mining calculation process is used to verify bitcoin transactions in the blockchain to ensure security, but the disadvantage is that it consumes a lot of energy.

1、 Mining principle

at the beginning, we could dig bitcoin with the computer CPU. The founder of bitcoin, Nakamoto Tsung, g out the world's first creation block with his computer CPU. However, the era of CPU mining has long passed, and now bitcoin mining is the era of ASIC mining and large-scale cluster mining

looking back on the mining history, bitcoin mining has gone through the following five times: CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining, The mining speed changes are as follows:

CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5tash / s) → large scale cluster mining (3.5tash / s * x)

mining speed, which is called computing power in professional terms, that is, the ability of computer to generate hash collisions per second. In other words, how many hash collisions can our miner do per second is the calculation force. Computing power is the ability to dig bitcoin. The higher the computing power, the more bitcoin you dig, the higher the return

in the world of bitcoin, a data block is recorded about every 10 minutes. All mining computers are trying to package the data block and submit it, and the person who successfully generates the data block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes

to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. You can only guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin

Mining method: from a miner to a large-scale mine, you need to prepare a miner, a computer that can connect to the Internet, an AUC, a raspberry pie, power supply and all kinds of connecting lines, etc. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply

< EM > Figure 3: Mine Map (scale of tens of thousands of mining machines) < / EM >

nowadays, the profit space of small and medium-sized absenteeism who take one mining machine home or deploy a small family workshop (dozens of mining machines) is very limited, and the mining instry is graally concentrating on enterprises and teams with low-cost power resources and professional deployment ability

there are many factors that affect the mining revenue, such as the performance and power consumption of mining machinery, the computing power and difficulty of the whole network, the deployment and operation and maintenance capacity of the mine, the availability of low-cost electricity resources, and the currency price and policy guidance, etc. At present, excellent mining enterprises have the ability of chip research and development, a lot of computing power, professional mine deployment and operation experience, etc. in the future, resources and computing power will be more and more concentrated in these mining enterprises

2. Mine pool

in addition to the above equipment, you also need a necessary tool - mine pool. The function of the mine pool is to gather a large amount of mineral computing power, increase your probability of getting bitcoin, and at the same time, distribute your future bitcoin income to your account in advance

the simple explanation is as follows: now the bitcoin network generates a block every 10 minutes, which contains 25 bitcoins. Suppose there are 1W people in the world participating in mining, then in these 10 minutes, only one lucky person has taken these 25 bitcoins, and the others have nothing. The principle of the mine pool is that everyone mines in teams and distributes according to the agreed distribution method, so that the income of the miners' bitcoin tends to be stable and the risks of the miners are reced. Let's take the most common PPS allocation method as an example. Suppose that your computing power is 10t, and the computing power of the whole mine pool is 100t. Your computing power accounts for 1 / 10 of the total computing power of the mine pool. Suppose that the mine pool can generate 10 bitcoins a day, then you can get 1 bitcoin a day

3. Cloud computing power

in reality, the supply of mining machines often exceeds the demand, and at the same time, the delivery of mining machines needs a long waiting period. Miner installation, commissioning, maintenance and other processes are very complex, which requires a lot of energy. Miners have to enre the noise and heat of miner. For miners, the biggest cost is not these, but the high electricity charges consumed by mining. The profit space of small and medium-sized miners is getting smaller and smaller, even negative

Mining income and risk mining income can be calculated by the following formula:

Mining income = generated bitcoin * currency price - mining machinery cost - electricity fee - custody fee

if you are just a small miner, generally you only need to dect mining machinery cost and electricity fee

Mining risks are as follows:

at present, the number of bitcoin is less than 4.5 million. If we do not issue additional bitcoin, the price of bitcoin will fluctuate, and the price callback will lead to the extension of the payback cycle

4. Bitcoin mining machine is the computer used to earn bitcoin. 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. One of the ways to get bitcoin is to download mining software and then run specific algorithm to communicate with remote server to get corresponding bitcoin
according to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have legal compensation and mandatory monetary attributes, is not a real currency, does not have the same legal status as currency, cannot and should not be used as currency in the market, and citizens' investment and transaction of virtual currency are not protected by law

The original intention of Nakamoto's design of bitcoin is to build a point-to-point trading network that is decentralized, transaction information can not be tampered with, and the total amount of money is constant, so as to solve the problems of excessive issuance of legal currency and inflation

this is the value of bitcoin's initial design, to keep the purchasing power of money

But later, the development of bitcoin went against Nakamoto's idea. In the past nine years, the price of bitcoin soared by millions of times, creating countless myths of sudden wealth and driving another instry mining

the value of bitcoin has become a tool for "sudden wealth". More and more people join the bitcoin network, hoping to achieve financial freedom. Digital cryptocurrencies such as bitcoin have become investment procts, like diamonds or gold

by purchasing bitcoin, people can achieve the purpose of wealth appreciation and asset preservation in many troubled areas. At the same time, many people make use of the fluctuation of bitcoin price to speculate, such as moving bricks, making bands and so on

another important value of bitcoin can not be ignored is blockchain, the underlying technology of bitcoin. Because of the popularity of bitcoin, many companies and indivials begin to pay attention to blockchain, and constantly try to use blockchain technology to change the existing business and create new value. It is with the help of bitcoin that blockchain has achieved such rapid development

bitcoin is also a great social experiment for all mankind, which promotes the reform of the financial instry and gives many original things a new perspective

6. Bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods
the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's ideas, open source software was designed and released, and P2P network was built on it. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system
unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation.

7. It's said that it's good to pick hemp. At that time, I foolishly went to certify the soldier, and I regret that I have no place to cry. But picking hemp is about to run around. If I were given another chance, I would certify the mining

Through the deep use of cryptography algorithm, specially designed data structure and multi-party consensus algorithm, blockchain uses machine algorithm to solve the consistency, reliable storage and anti tampering problems of multi-party transaction records, which has a natural strong correlation with electronic data storage

first of all, the electronic contract signing records are stored in the shared account book jointly maintained by multiple parties, which can not be tampered with, denied, and of course will not be lost

secondly, electronic contract text and electronic contract elements are encrypted, including electronic contract participants. Only participants can decrypt and view the data to protect the privacy of the parties

thirdly, the machine strictly implements the pre-defined rules (smart contract), and no longer only relies on a single agreement with a third party. KYC service based on blockchain automatically checks and verifies the validity and identity of certificates, and ensures the authenticity of participants' identities on the basis of privacy

at present, the electronic contract signed on the advanced electronic contract platform has realized the distributed storage of digital fingerprints of electronic documents through the blockchain technology, which further strengthens the legal effect of the platform electronic contract

9. Bitcoin is characterized by anonymity, global access and decentralization, so bitcoin has its value
the value of bitcoin:
1. Avoid war, keep value, etc. If a country is in chaos, bitcoin will become the first choice for many people. Although gold is more stable, it is not convenient to carry. If the country is in chaos, who dares to carry a lot of valuables out? But bitcoin is different, as long as you remember the key of the wallet (many wallets are written with mnemonic words), even if you go empty handed, arrive at a safe place to download a wallet, and enter the correct key to take it out
2. It is used in some gray instries. For example, in the year of 17, the global computer virus blackmail event was bitcoin for blackmail
of course, there are others, mainly these.

10. With a large number of mining machines put into operation, more and more miners join the mining army. Now it's more and more difficult to dig independently. It's hard to work for a month, and the harvest is very small. What should we do? It's undoubtedly a good way to join the new rising cloud miner

let's first introce cloud miner. From the name point of view, it's mining in the cloud (that is, the server). Its basic principle is that you can obtain the mining income corresponding to computing power by purchasing computing power with bitcoin. The more computing power you buy, the higher the mining revenue will be. When not in use, you can also convert the computing power back to bitcoin. In a word, you can revitalize the bitcoin on hand. Money generates money and money supports money

now if I ask you, do you spend a lot of bitcoin to buy mining machines, or let bitcoin sleep in the trading website or wallet, or use it to invest in cloud miners to generate income. It's up to everyone to figure it out< Compared with the traditional mining machine, the advantages of cloud miner are as follows: 1)
cash is more flexible. Compared with spending a lot of bitcoin to buy mining machines, buying cloud miner's bitcoin is easier to cash, and you can sell the computing power at any time to exchange it back. 2) With small investment, idle bitcoin can be used. Compared with tens of thousands of mining machines, cloud miner can invest as little as a few coins according to your specific situation, and there is no limit to the upper limit

if you still don't understand, you can register an account https://cex.io/r/0/anemone/0/ Look, it's free anyway. It's very clear how to buy and sell computing power with bitcoin, and how to increase mining revenue< It's not recommended to mine with personal computer.

advantages of using cloud Miner: the difficulty of mining bitcoin is 707408283, and the top-level graphics card of hd7990 has a mining speed of only 1000m, and the mining machine often costs tens of thousands of yuan, which is not guaranteed or guaranteed, so the mining risk is greatly increased. Using cloud mining machine does not need management, will not break down, hundreds of yuan can also participate in, can buy and sell computing power at any time, convenient exit. The following is a brief introction of how to register and purchase cloud computing power. PS: the current price is about 0.7. Generally speaking, if bitcoin appreciation, the price will fall, and it will also be slightly affected by buying and selling
