2. Technical analysis ： Feasible mining samples in the current network

I have been fighting against the mining Trojan horse in the public cloud for a long time , The thought of dogecoin Recently, with such great influence , Whether it will encourage the black ash industry team and crazy speculators to start crazy money digging for public cloud servers , Affect the security and availability of the public cloud server ？ So , Study the mining mode of dog coins .

（ The details of mining technology for dog coin are not explained in detail in this article , There are many tutorials throughout the network . Combine these tutorials , The following mining conclusions are summarized ）

The output mode of dog coins ：

Merge mining （ Or joint mining ）： Dog money “ Merge ” Mining refers to working with all people who have S The currency of the algorithm “ Merge ” dig , Is to give others s A choice of algorithm , You can dig the others alone s The currency of the algorithm , You can also dig other s While calculating coins, it also provides computing power for dog coins , Dogcoin network accepts this kind of computing power contribution , It is called auxiliary workload proof mechanism . let me put it another way , all s You can choose to dig dog coins at the same time . Because the current s The main calculation power of the algorithm is focused on Wright coins , So it seems to have the greatest impact on the Wright coin .

2.2 Technical summary

1. Three feasible mining methods ：
  （1） memory >4G GPU dig    Currency production rate ： Average 10 individual / God                    
  （2） memory >4G GPU dig    Currency production rate ： Average 5 individual / God                    
  （3）CPU dig           Currency production rate ： Average 0.006 individual / nucleus / God                    
2. Dog money use GPU The mining rate is much higher than CPU Mining rate 
3. The operating system applicable to the mining machine ： Limited to Windows System , Because there are few ore pools supporting dogcoin mining , Use linux The system cannot be dug out

3. Income analysis

The recent average price of dog coins is ￥3 element One , At the same time, the proportion of the ore pool to the mining income is 1%, The average household electricity charge is ￥0.6 element / degree , One day CPU Average power consumption for mining 0.15 degree / Hours ,GPU Mining consumes electricity CPU Mining 5 times ,GPU Average power consumption for mining 0.75 degree / Hours , Let's calculate , How much profit can the above mining methods bring ？ With Daily income Calculate in units ：

3.1 memory >4G GPU Daily mining income

Before starting the calculation , Let's take a look at one that meets the basic performance GPU Mining graphics card GTX1660 The price of , The average price is 1800 element , The service life is 3 Months ~6 Months , count 6 Months

 Daily expenditure cost ：
      Electricity costs ：0.75（ degree / Hours ）* 24（ Hours ）* 0.6（ element / degree ）= 10.8  element 
      Graphics card loss cost ：1800（ element ）/ 6（ month ）/ 30（ God ）= 10  element 
 Daily income ：10（ individual / God ） * 3（ element / individual ）* 99% = 29.7  element 
 Daily gross profit ：29.7（ element ）- 10.8（ element ）- 10（ element ）= 8.9  element 

3.2 memory <4G GPU Daily mining income

We have the highest configuration GTX1650 The graphics card 4G Video memory and graphics card calculation , Average price 1000 element / strip

 Daily expenditure cost ：
      Electricity costs ：0.75（ degree / Hours ）* 24（ Hours ）* 0.6（ element / degree ）= 10.8  element 
      Graphics card loss cost ：1000（ element ）/ 6（ month ）/ 30（ God ）= 5.56  element 
 Daily income ：5（ individual / God ） * 3（ element / individual ）* 99%（ There is a surplus of water pumped from the ore pool ） = 14.85  element 
 Daily gross profit ：14.85（ element ）- 10.8（ element ）-5.56（ element ）= -1.51  element 

3.3 CPU Daily income from single core mining

CPU The loss cost is ignored here , Average service life 6 year , Negligible

 Daily electricity cost ：0.15（ degree / Hours ）* 24（ Hours ）* 0.6（ element / degree ）= 2.16  element 
 Daily income ：0.0006（ individual / God ） * 3（ element / individual ）* 99% = 0.001782  element 
 Daily gross profit ：0.001782（ element ）- 2.16（ element ）= -2.158218  element 

3.4 Benefit conclusion

 memory >4G GPU Daily mining income ： 8.9  element / God 
 memory <4G GPU Daily mining income ：-1.51  element / God 
CPU Daily income from single core mining ：-2.158218  element / God 

Deficit ！

4. Security impact analysis on public cloud servers

Combine the technical level with the income level , Let's go back to the beginning of the article ：

dogecoin Recently, with such great influence , Whether it will encourage the black ash industry team and crazy speculators to start crazy money digging for public cloud servers , Affect the security and availability of the public cloud server ？

 One . Technical summary ：
1. Three feasible mining methods ：
  （1） memory >4G GPU dig    Currency production rate ： Average 10 individual / God                    
  （2） memory >4G GPU dig    Currency production rate ： Average 5 individual / God                    
  （3）CPU dig           Currency production rate ： Average 0.006 individual / nucleus / God                    
2. Dog money use GPU The mining rate is much higher than CPU Mining rate 
3. The operating system applicable to the mining machine ： Limited to Windows System , Because there are few ore pools supporting dogcoin mining , Use linux The system cannot be dug out 

 Two . Revenue summary ：
1. memory >4G GPU Daily mining income ： 8.9  element / God 
2. memory <4G GPU Daily mining income ：-1.51  element / God 
3.CPU Daily income from single core mining ：-2.158218  element / God 

One sentence answer ： Can't ！

Why? ？

The general server configuration of the public cloud does not have a graphics card ！ You can only use CPU Come and dig ！ One day Lose money 2.158218 element ！！, The cost of ECS is not included here ！

OK, Someone will say , I will use the public cloud GPU Server to dig .GPU Server one month 2500+ Yuan minimum configuration cost , It's more expensive than you buy a graphics card ！

From the perspective of humanity , I believe that anyone who understands this account can calculate it .

How to write the word "loss" ？

5. Conclusion

Public cloud Dog Coin dogecoin Mining trend analysis ： Due to currency Dogecoin With GPU Mining is the main output , It will not affect the regular public cloud linux The server , May affect a small number of windows The server .
