R1800 mining

1. This trojan takes advantage of the "eternal blue" vulnerability to attack and spread in the local area network. It builds a robust botnet of the infected machine, supports the self-renewal of the intranet, and lurks in the computer for a long time to extract Monroe money. Because most ordinary personal computers have been patched by windows security update and Tencent computer manager and other security software, they are basically not affected by wanna miner. It is suggested that if the suspected wanna miner mining Trojan horse is found, the poisoned machine can be located and isolated in time. It can be judged by scanning port 26931. If the port is open, the host has been infected; If you need to patch the intranet, all the computers that have not been patched. It is suggested that professional terminal security management software should be installed in the whole network, such as Tencent Yudian. The administrator should carry out mass antivirus and patch installation for the whole network to avoid unnecessary losses.

Ethernet mining tutorial

1. Create a new folder on the hard disk, which is better than C: eth. Then all the mining software is stored here

2. Download the following software

1) geth -- select geth win download and unzip

2) ethernet -- download and unzip to the same folder and rename it as "miner"

3) Ethereum wallet -- Download the win Ethereum wallet and unzip it and rename it as "wallet"

install all the software

3 Open the command prompt (click win and R at the same time, or click Start menu and enter CMD). The command prompt is a command line parser that allows you to execute command input software in the operating system

After

, you will have Ethereum wallet. But there is no balance, so next you need to build an ethminer. It's time to minimize your wallet

Mining

It's about 37 yuan

let me first introce the reward mechanism of bitcoin system

bitcoin can basically dig out a block every 10 minutes through system settings. The reward for each block is given to the miners who dig out the block. The miner who digs out the block is called the block miner. The block miner will record the legal transactions in the bitcoin network to the blockchain, so that the miner can receive the service charge for bookkeeping

there are two parts in the reward for the block Miner: one part is the reward given by the system, which is called coinbase reward (also known as system issuance reward), the other part is the reward for bookkeeping, which is called miner's fee. The coinbase reward started with 50 bitcoins. For every integral multiple of 210000 blocks, the coinbase reward will be halved. This is what we often hear about bitcoin mining reward halved in four years

at the present stage, the reward of coinbase is 12.5 bitcoins. At the present stage, the average transaction miner fee received by miners for digging out a block is about 0.1 bitcoin (not fixed), that is to say, the average reward received by miners for digging out a block is about 12.6 bitcoin

about 99% of miners' rewards come from the system's coinbase rewards. According to the bitcoin system, one block can be g out every 10 minutes on average. The number of new blocks that can be g out in one day is 144 (60 * 24 / 10 = 144). At present, the number of bitcoins that can be g out every day is 1800btc (144 * 12.5btc = 1800btc). With the miner's fee of about 0.1btc per block, the total reward for all miners in one day is about 1814.4btc

Mining is the use of bitcoin mining machine, which is used to earn bitcoin

one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, 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. Considering the hardware price and other costs, there is a considerable expenditure in mining

< H2 > extended data:

bitcoin mining process:

1. To find the ore pool

to start mining, there must be a ore pool with convenient operation and stable output. Its function is to subdivide the data packets for each terminal, and pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through precise algorithm

2. Download bitcoin miner (software)

in fact, there are many kinds of this miner, you can go to the official website to download

3. Setting mining software is a green software. After installation, we can set the language first to facilitate further setting. Next, you need to set the server, user name, password, equipment and so on. Generally, the server chooses a better network from BTC guide series, and the user name and password are set by ourselves before

4, bitcoin mining start

when we confirm that all settings are correct, click the "start mining" button to start bitcoin mining, and then the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, you can monitor the state through gpu-z or graphics card driver

5. A / R, which often appears in the mining pool, is the acceptance / rejection value: the unit of measurement allocated to the miners in the mining pool is stock. Whoever has more calculating power has more stocks. I got a lot of money

however, e to the influence of network or pool allocation, some stocks are generally rejected, that is, the obsolete and invalid stocks you see

generally speaking, the ratio of accept / reject is 10:1, even if many times it is 5:1, too much is the problem of the network

as a digression, it's not enough for the electricity bill whether you want to dig the 405 n card or not. And look at you digging in deep. It's a BTC mine. Now there's no BTC mining with graphics card. I can't dig anything. I'm losing money

if you want to dig, you should use high-end a card to dig LTC or something. It doesn't make much.

6. First of all, you have to have a mining machine, which is not approved by the mining country. The mining machine is very expensive and may be cheated. I suggest you stop mining.

7. R5240 is only able to mine in theory, but the energy consumption ratio is not cost-effective, the electricity bill can not be earned, and the calculation power is too low. It takes hundreds of years to dig one, so there is no significance of mining in practice.

9. It should be related to the associated list. When the associated list is finished, it can be put forward<
the CBRC, the Ministry of instry and information technology, the people's Bank of China and the State Administration for Instry and Commerce suggest that in recent years, in the name of "financial mutual assistance", the behavior of promising high returns and luring the public to invest funds has appeared in many places in China. Its main characteristics include: 1
first, there are many names. Common are: "XX financial mutual aid community", "XX financial mutual aid platform", "XX financial mutual aid financing", "XX charity financial mutual aid platform", "XX financial mutual aid investment", "XX mutual aid community", "XX wealth mutual aid platform", etc< Second, it develops rapidly. Relying on the Internet, through the website, blog, wechat, QQ and other platforms, the publicity has a wide range
thirdly, it is confusing. Under the banner of "overseas celebrities", some claim to "destroy the unfair world financial system, break the control of financiers, and create a community for ordinary people" as the goal. Through the establishment of the so-called "fair, just, mutually beneficial and honest financial platform for people to help others", the public can get more help by subsidizing others. At the same time, he falsely claimed that "after market test, he has been mature in many countries for many years, and has hundreds of millions of members in the world" and so on
4. Strong incement. It claims that the investment threshold is low, the cycle is short and the income is high. For example, after free registration, the investment of RMB 60000-60000 can be withdrawn after 15 days, with daily income of 1%, monthly income of 30%, annual income of 23 times, and no handling charge. In addition, if participants develop others to join, they can also get extra income such as recommendation Award (10% of offline investment) and Management Award (the corresponding proportion is determined according to the membership level). There is no upper limit for development personnel and no upper limit for rebate< 5. Strong concealment. Most of them are controlled remotely by overseas personnel, and the investment funds are often transferred through personal bank accounts or through third-party payment platforms
this kind of operation mode violates the law of value, and it is difficult to maintain the capital operation for a long time. Once the capital chain breaks, investors will face serious losses. The general public is requested to raise their awareness of risks, invest rationally and prudently, and prevent their interests from being damaged. At the same time, we can actively report to the relevant departments the clues we have learned about crimes
bitcoin home and many mainstream media have reported similar virtual money pyramid schemes.

10. In fact, golden curvature must be combined with screen size to make sense. After all, for small screen display, e to the close viewing distance, at this time, smaller curvature, more curved screen is concive to better reflect the sense of encirclement. The game player pf40fc is a 38.5-inch display. When such a display is in normal use, it is usually about two meters away from the display. At this time, only by increasing the curvature of the display can the distance between each pixel and the human eye be consistent, so as to obtain better display effect. The R1800 is a better choice for medium and small screens, while the large curvature is more suitable for large screens.
