Characteristics of mining process
bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it
mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash
and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on
extended data:
mining risk:
1, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
2, system risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
a new customer recently consulted with sine security company, saying that his server often fails to open the website of the card, and the remote connection to the server is extremely slow. Sometimes the Ping value reaches 300-500, and he often switches. After listening to the customer's words,
will generally judge that he has been attacked by CC + DDoS mixed traffic, It's strange to say that there is no traffic attack on the computer room. It's not a traffic attack, but it also causes the server card and website to fail to open. What kind of attack is this? In order to solve the problem of
client server card, we immediately arranged a security engineer to carry out security detection and deployment on his Linux server
{rrrrrrr}
Mining Trojan horse is also designed. If the mining process is forced to stop by customers, it will automatically start to continue mining to achieve uninterrupted mining.
careful inspection shows that it is through setting the hourly task plan, remotely downloading shell mining Trojan horse, and then executing, Check whether the current process exists or not. If not, start the Trojan horse to mine
a detailed security inspection was carried out on the client's Linux server. It was found that fortunately, there was no encrypted server data, and the worm was infected with the disease through the security detection and analysis of our security engineers, we found that the server uses Apache Tomcat environment, the open architecture of the platform is JSP + Oracle database, and Apache Tomcat uses the version of 2016, which leads to the serious remote command execution vulnerability of Apache, Through this vulnerability, the intruder can directly invade the server and get the administrator permission of the server,
virus. If the data was encrypted, the loss would be great. The client was a platform, and the client's data was very important. After finding out the mining Trojan horse,
do customers need to know how the server is attacked? Was the Trojan horse uploaded? It can prevent the attack
in the later stage
sine security engineer immediately repairs the Apache vulnerability and clears the Trojan horse. So far, the problem has been solved, the client server
runs stably, and the network station opens normally
The price of bitcoin mining machine ranges from two or three hundred yuan to 200000 yuan. From 2011 to 2013, the high configuration bitcoin "mining machine" increased from 10000 yuan to 300000 yuan, but its performance is much better than before. According to instry insiders, the old machine can only dig 1 bitcoin in 100 days, but now (2013) machine can dig 3.5 bitcoins in 100 days
according to the miner information published by the domestic assembly team, a miner with the lowest configuration at the price of 3000 yuan can be returned in more than 30 days according to the bitcoin mining speed. The machine with mining speed of 10G / s can dig about 0.03 bitcoins 24 hours a day, while the machine with mining speed of 13g / s can dig about 0.035 bitcoins 24 hours a day according to the computing power and difficulty of the whole network in 2013. Mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, the computing power after "grouping" can surpass the single graphics card of most users. And this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Taking into account the hardware price and other costs, there is a considerable expenditure in mining< br />
Compared with other instries, the proction environment and process of mining have the following characteristics:
(1) the main raw materials for mining and processing are naturally occurring ore bodies. The mine site cannot be selected freely, and the instrial reserves of the deposit cannot be imported or regenerated. The proction capacity, service life and economic benefit of the mine are closely related. Every mine has to go through the process of mine construction, proction, normal proction, proction rection and mine closure
(2) mining equipment and personnel are often transferred with the mining process and processing objects, and there is no fixed processing workshop. The mined ore body must be excavated a series of roadways to prepare for mining. Development, mining and stoping should be coordinated to ensure the normal proction of the mine. Otherwise, it will lead to mining and stripping imbalance or mining imbalance, forcing the mine to rece proction
(3) the general trend of mining work is that the mining conditions are getting worse and worse, the grade of mined ore is graally decreasing, and then the cost may increase. Due to the mixing of rock, the ore will be poor and the quality will be reced, and some of the ore can not be mined and lost underground. Therefore, it is necessary to continuously improve the mining and mineral processing technology and carry out comprehensive utilization to rece the cost. Recing dilution rate and loss rate is an important quality management work in mining proction, which has great economic potential< (4) the occurrence conditions and shape of ore bodies are complex, and the grade distribution is uneven. The instrial reserves may have great changes in the mining process, which makes it difficult to standardize the mining design. In addition, the mining construction period is long, and the infrastructure investment is large, so the investment risk is also large
(5) mining work is in open pit or underground stope. Due to large amount of labor, poor working conditions and poor safety, it is difficult to realize comprehensive mechanization and automation, so special attention should be paid to improving labor protection and environmental conditions
(6) the operation effect of a mine is largely determined by the market supply and demand and value of the mined ore. Therefore, the evaluation of mine management level should not be based on absolute economic benefits just like other instries
the traffic ore system is a crowdsourcing cloud computing solution. It collects scattered bandwidth and CPU, and makes optimized real-time deployment through cloud computing to help major video stations solve the instry dilemma of insufficient bandwidth and low utilization of purchased bandwidth< According to the introction of the official website, traffic ore includes two systems:
1. Mining client helps computers, servers and even mobile terminals contribute idle bandwidth and CPU, and measures the contribution value in terms of traffic ore
2. In the trading system, users buy and sell the traffic ore corresponding to the bandwidth they contribute and get the corresponding return
after the user installs the mining client port, the client will use the idle CPU and bandwidth resources of the user terminal to process the cloud computing tasks distributed by the server, so as to obtain the valuable asset traffic ore. Then the flow in the account can be converted into cash in the trading system
how to operate this mining machine? What else do you want? How much do you make an hour? I'm afraid many people are concerned about this
the mining machine does not need task operation, you just need to go to the official website to get up and down the client, and hang up after installation, you can automatically complete the whole mining work. There are not too many requirements for configuration. General PC can mine. But Xiaobian feels that the core factor of mining speed is related to your upload bandwidth (uplink), which is not good news for home bandwidth. For example, the telecom home bandwidth is 20m, and the uplink does not even have 1m; But the general enterprise bandwidth is not the same, sometimes even up and down peer, if you are not afraid of being caught by the leadership, you can hang up a try, here is not to encourage! Some data are listed below for reference:
hoe: & lt= 100kb / s, it takes about 4 days to proce 1kg ore
shovel: 100-3000kb / s, it takes about 12 hours
mining machine: 3-20mb / s, it takes about 1 hour
blasting machine: 20-50mb / s, it takes about 15 minutes
gold panning robot: & gt; 50MB / s, less than 50 seconds
of course, will mining affect the normal use of the computer? Xiaobian test, for online games, it will automatically identify the mode and does not affect your homework process, but it affects the speed of watching video! But you can set the mining speed
if you find ore, you can trade it on the official website of flow ore! If you are interested, you can try it yourself!
