1. Back up important data and photos and restore factory settings. Don't install applications from unknown sources. In addition, don't authorize in permission settings

2. You can swipe the computer to see if it can't work. Besides, the computer needs to clean up the memory on time so that it won't get stuck. The memory of the mobile phone is seriously insufficient. It is recommended to clean up the memory lightly, and then restart your mobile phone again

3. Clear the data of the mobile phone. If there are important things, save them on the network disk first, and then restore the factory settings three times. This is safer

< H2 > extended data:

1. Set the security level of the browser. Our common browsers all have the function of security level setting. Through reasonable setting, we can effectively filter the access restrictions of some illegal websites, so as to rece the damage to computers and personal information

2. Firmly resist reactionary, pornographic and violent websites. On the one hand, these bad information will affect the physical and mental health of teenagers, on the other hand, many illegal websites will use browser vulnerabilities to attack users

3. Don't click illegal links at will

When downloading software and materials, we should choose the regular website or official website

5. Turn off some sensitive functions in common communication software. Such as "people nearby" in wechat and "allowing strangers to view photos" in wechat privacy

6. Do not take photos of your family and address. If it goes on like this for a long time, as long as it is analyzed and summarized by others, the information exposed will become a complete set of information, which hides all kinds of unpredictable risks

Do not test related information on the Internet. Some websites do surveys and ask for information about age, hobbies, gender, etc. to do it for a small profit. This information may be used by others, and graally summarized, and sold to others for profit or threat

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

mining difficulty improvement at present, our machines can meet the market demand

3. After turning on the computer, check whether the light of the network cable interface on the back of the host is on. If it is not on, it means that the network cable is not connected well

right click my computer to check whether your network card works normally in the device manager

if the reason for the network card is excluded, right-click on the network neighbor, properties, right-click on the local connection, open the internet protocol, select to automatically obtain the IP address and DNS server address, and confirm to save it

as long as the network card works normally and the settings are correct, the reason has nothing to do with the computer, Can be ruled out is the machine fault

4. Domestic mining machinery (the current situation analysis, has the following disadvantages):
A. more than 95% of the domestic IP addresses are not static, resulting in mining default platform withholding pledge token
B. they need to buy pledge token, and spend some extra money to buy token to start up
C. the sound of power off is loud, Unfortunately, your family is in the second, third, fourth and fifth tier cities, and basically can't get orders.
e. the home miner advertised by a Yingkuang machine can't mine and can be retrieved. The retrieval needs an uplink bandwidth of at least 10m, and the space-time proof (IPFs anti cheating mechanism) may need a stable bandwidth of more than 20m, Who's community network within 24 hours to meet the above requirements, so retrieval is also very difficult
therefore, instead of spending a lot of time, it's better to directly find a company for hosting. If you don't know anything, you can also consult me.

5. Mining needs networking, and it takes up a lot of resources. Mining are using professional high configuration computer, general computer running mining machine is very difficult, and buy a mining machine software to sky high price, advise the landlord if you don't want computer retirement or don't use mining good, computer can't, mobile phone don't want to..

1. First of all, connect the network cable, plug the network cable into the network cable interface of the mining machine, and remember to plug it tightly. Only when the miner is connected to the Internet, there is no limit to the broadband

extended data

users can buy bitcoin, at the same time, they can also use computers to "mine" bitcoin according to a large number of calculations. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a set of numbers, then they will get 25 bitcoins

e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes

7. The purpose of mining is to package the transaction block. If the package is successful, you will open a new package and get a 25 bitcoin reward, as well as the handling charge for the future transactions added to the package. Then other miners will start to package the transaction generated by your new package until the next package comes out first. In the future, the mining capacity of bitcoin will be small or even zero. You still have transaction fees. The system will always need miners, and mining machines will still exist.

8. It's not reliable to watch. You must be careful

9. Mining system is added in Marvel Mu S8 version
mining tools can be purchased from NPC with one blessing gem. It can be mined in various safe areas, including all kinds of gems. The rability of mining tools needs to be repaired with blessing gems.
