Mining in University Teachers' room

1.

In short, mining is the use of chips for a random number related calculation, get the answer in exchange for a virtual currency. Virtual currency can be exchanged for the currency of each country through some way. The stronger the computing power, the faster the chip can find this random answer. Theoretically, the more virtual coins can be proced per unit time. Because it's about random numbers, you can only get rewards if you happen to find the answer

In his paper, Nakamoto stated:

"in the absence of central authority, it not only encourages miners to support bitcoin network, but also enables bitcoin's currency circulation system to have the initial source of money injection."

Nakamoto compares the generation of bitcoin by consuming CPU power and time to the consumption of resources by gold mines to inject gold into the economy. Bitcoin mining and node software mainly initiates zero knowledge proof and verification transactions through peer-to-peer network, digital signature and interactive proof system

each network node concts broadcast transactions to the network. After these broadcast transactions are verified by miners (computers on the network), miners can use their own work proof results to express their confirmation. The confirmed transactions will be packaged into data blocks, and the data blocks will form a continuous data block chain

Nakamoto himself designed the first version of bitcoin mining program, which was later developed into the first generation of widely used mining software bitcoin, which was popular from 2009 to mid-2010

each bitcoin node will collect all the unconfirmed transactions and gather them into a data block. The miner node will add a random adjustment number and calculate the SHA-256 hash value of the previous data block. The mining node tries again and again until it finds the random adjustment number so that the hash value is lower than a specific target

extended data

at the earliest, bitcoin miners were mining through Intel or AMD CPU procts. But because mining is a computing intensive application, and with the continuous improvement of mining number and equipment performance, the difficulty graally increases, now using CPU mining has no profit or even loss

as of 2012, since the first quarter of 2013, miners graally began to use GPU or FPGA and other mining equipment [5]. At the same time, a large number of ASIC devices were launched in mid 2013

since July 2013, the computing power of the whole network has shown a straight-line rise e to the large number of ASIC equipment put into operation. Based on the average computing power in July 2013, all CPU mining equipment has been unable to generate positive revenue, and FPGA equipment is close to no revenue

according to the estimation of average computing power in September 2013, the existing small ASIC mining equipment developed for indivials will also be close to no positive revenue in the next 1-2 months. A large amount of computing power is monopolized by cluster ASIC mining equipment with 5 th ash / s or more. Because of no profit, indivial mining is almost squeezed out of mining groups. Some bitcoin miners have raised funds to build machine rooms and install a large number of mining equipment in places where low-cost electricity can be obtained

in order to save the cost of mining, some bitcoin miners make mining programs into malicious programs to infect other people's computers on the network to mine for themselves

2. In fact, not much harm, mainly equipment radiation, eat more anti radiation dishes. Of course, the radiation value should also be within the safe range, don't worry......

3. I remember it's 20000 for the intermediate level to the senior level, 8000 for the first level, and forget it for the junior level. It should add up to about 30000. Very good, just eight a month.

4. Should suggest the school. Internet speed up. A mining card. Public organs of the equipment is like this. Really bad
you should thank the mining man and point out the serious shortcomings of the school computer room

5. Many of them (including me) have selected the miner skills, that is, the one with mining quantity + 1. Generally, there are not many gems, because in the middle and later period, gems are only used for synthesizing indivial equipment, but the ore is very important from the beginning to the end, which is really very useful. What's more, there's a gem ing machine in the back. If one changes two, the gems will be sold later. But with a greenhouse, who needs to sell gems? Making money from agricultural drinks is a terror!

6. infeasible. Mining needs a lot of electricity. The computer room does not support it.

7. However, thousands of computers running at the same time how spectacular electricity charges!!! How do you make the assignment when school begins
other people's mines rely on the surplus electricity of small hydropower stations. I feel that they are making some coolie money. If the mining profits are too high, why should they cut the electricity bill... So when you're ready for the electricity bill of 1000 computers for two months, start mining boldly!

8. The family has the risk of network outage, NAT internal and external network penetration problems, public IP problems and the family bandwidth can not meet the mining requirements, so we must enter the IDC room.

9. Is the layout of IDC room important? Is there any difference between mining in small villages and big cities
big cities

10. Mine diggers are,
