How to pay for the miner's fee in Xinghuo mine
this is mainly e to the 51% attack, because before some of the world's well-known mines, e to the low rate and convenient use, many miners went to those large mines to mine. As a result, the computing power of the mines soared, approaching or even exceeding 51% of the global computing power many times
bitcoin community has also raised a big discussion about 51% attack for many times,. The mine pool operators also called on the miners to move to other mines in a responsible manner, and finally 51% of the attacks were solved. Many of China's miners have moved to fish ponds
most of the new miners have joined the fish pond because they don't know about the global mine ponds, and many of the previous mines have died e to poor management
The graphics card market in 2017 is the most special in recent years. In the past few years, no graphics card will increase its price by 100% a few months after its release. RX 580 has achieved this goal. Together with all the graphics cards below 3000 yuan, it has broken through the premium point in an irresistible manner. All this happened with the bitcoin price breaking through 3000 US dollars. After miners swept the RMB 2000 RX 580, the price of low-end RX 560 and even GTX 1050 Ti increased to varying degrees. However, is the price directly proportional to the ability of hash algorithm? Recently, we did a test to collect the new generation of graphics cards at various prices on the market, test the mining speed of Ethernet and bitcoin, and see which card has the highest cost performance
Different from the thousand yuan market, this wave of mining tide has a great impact on high-end graphics cards. In the test results, RX 580 and Rx 480 have almost reached the bottom of GTX 1070. Moreover, the price of Rx 580 is even competing with that of GTX 1070, so the miners directly swept the 3000 yuan market when GTX 1060 3gb / 6GB is out of stock, and GTX 1070 is basically out of stock. The more advanced GTX 1080 is also out of stock, but it's not clear whether the players are forced to go directly to the high-end card or the miners extend their claws to this market. The situation of GTX 1080 ti is only slightly improved, but it's not much better. However, not everyone can afford the 6000 yuan graphics card. Only the top players will be affected, but it's just a narrower choice. It's not the case that the rich can't buy itsummary:
to mine, the first choice is the graphics card with more than 3gb video memory, which is the basis. In addition, the core frequency will affect the mining speed. We have two GTX 1080 cards on hand, one is public version, and the other is MSI GTX 1080 gaming X. the operating frequencies of the two cards are 1885mhz and 1936mhz respectively. After testing, because of the frequency, the latter will be about 4% faster than the former in actual mining. The advantages of high-frequency graphics card are highlighted
So Xiaobian's opinions and suggestions are as follows:the low-end card and the old architecture card are not suitable for mining. GTX 1080 ti is an extreme, with the most powerful performance, but the price is not suitable for large-scale procurement. The mining speed of a card with the same location is much faster than that of N card, The cost performance of GTX 1060 3gb is higher than that of GTX 1060 6GB. The frequency and the number of stream processors / CUDA have a great influence on the performance of the card. The size of video memory has no influence on the mining. It's enough. Different video cards will have different profits if they dig different coins. If you want to further explore, you need to test several currencies, Limited to space, we only select two representative currencies to test
as long as the mine disaster does not occur, the shortage will last for a long time. However, if there is a mine disaster, a large number of second-hand mine cards will directly enter the market. These cards are always running at full load and full speed, and their service life is greatly shortened compared with that of ordinary users. Even if the price is lower, they will roll over at any time, There is no need to start at all. Moreover, the second-hand market will be directly disrupted. At that time, it will be difficult for some normal users to get out of the second-hand market, and the deep-water fish's Dragon killing knife will explode the galaxy. Now it is said that NVIDIA is making some graphics cards without display output interface, which are provided to miners as mine cards. With a certain capacity, if the mine card still can't satisfy the miners, won't the miners buy the graphics card in the consumer market? The only function of these special mine cards is to prevent mine cards from flowing into the second-hand market, which can not alleviate the current shortage of graphics cards
how to mine a mine pool
the location of a mine pool is also very particular. It's not that a mine pool can be built anywhere, but it needs early-stage capital investment. A mine pool is to combine a single mining machine together. Because of the collection of many miners' computing power, the computing power of the mine pool accounts for a large proportion, and the probability of digging bitcoin is higher. The mine pool will distribute rewards according to the contribution value of each equipment
there are many mines all over the world, and the scale of each mine varies from big to small. Generally, small mines no longer have great advantages. Large mines have many miners for mining. For each miner, he can join any mine or join multiple mines at the same time, The first task of the mine pool is to distribute the income to the miners
(1) PPLNs method
this method gathers the shares g by all miners together. Whenever a certain amount of shares is accumulated (generally 30 million shares), the mine pool will allocate the profits of the previous stage to the miners according to the proportion of contribution
in this way, the income of miners depends entirely on the time needed to dig 30 million shares in the mine pool. If you are lucky, you can dig them in a short time, then the income of miners will be more, otherwise it will be less. In return, the pool charges a 3% tax
(2) PPS mode
for users, the income of this mode is relatively stable
the profit mainly depends on the miner's mining speed. As long as the mining speed is stable, the corresponding profit can be obtained, and the profit is real-time, that is, the mine pool will pay the profit for the miner while the miner is running
obviously, every time a block is calculated, the mine pool has paid for all the miners. If the block fails in the subsequent confirmation link, all the losses will be paid by the pool operator. Therefore, this method reces the risk of the miners, but transfers the risk to the pool operator
therefore, usually the ore pool can charge a handling fee to make up for the possible losses caused by these risks. In this mode, the tax of the ore pool is 7.5%
the above is about how to mine. The difficulty of mining has greatly increased, but the mining army is expanding. If the basic equipment does not meet the standard, it will be difficult to gain in the mining instry, because the value of the virtual currency may not be equal to the price of an equipment, and many miners are not just digging bitcoin, Instead, we choose other virtual currencies to mine.

justice heirloom and honor heirloom have the same parts, but the application direction is different. The Trade Union merchant also sells a cape. It depends on your trade union reputation. Maybe you don't have enough reputation.
there are also agricultural procts like rice, oil and so on
for example, vonetracer traceability system of wangchain technology is related to us.
with the rapid development of human high technology, the side effects of science are graally reflected. Global warming is an example. Hot weather, in the heat bubble air conditioning has become a new "hobby", but people have thought, air conditioning will bring any negative impact? The answer, of course, is yes. Air conditioning emissions contain a lot of methane, which is also a gas that causes global warming. At the same time, air conditioning will waste a lot of electricity, so try to avoid using air conditioning, appropriate< Another reason is: carbon dioxide! Car exhaust and factory exhaust contain a lot of carbon dioxide, and carbon dioxide is most likely to lead to the greenhouse effect (that is, global warming). Now the number of cars is graally increasing. According to relevant statistics, by the 21st century, there are 700 million cars in the world. A lot of exhaust seriously affects us, cough, throat inflammation... The most important thing is global warming. According to statistics, the per capita carbon dioxide emission of the United States has reached 20 tons a year! China's annual carbon dioxide emissions per capita emissions are 2.51 tons a year! The environment around us is changing badly
the more important reasons are as follows: forests have been sharply reced, water resources have been destroyed, ecological chain has been seriously damaged, a large number of land is barren, and water pollution is serious. According to statistics, 10% of the world's river water has been polluted, and fresh water supply has become a problem. At the same time, e to the extensive use of minerals, the burning CO2 gas has led to air pollution, and the ozone layer has been seriously damaged, The ozone holes in the north and south poles have exacerbated the deterioration of the environment. Such a vicious circle will eventually lead to a serious impact on people's lives
what is the tragedy? Obviously! The weather is heating, sea level is rising, glaciers in the north and south poles are melting, coastal cities and island countries are flooded. All these have seriously affected the survival of human beings. Experiments have proved that sea level will rise by more than half a meter in the next 300 years, which is still the most optimistic data. In another seven years, global warming will continue irreversibly. What's more, as the Arctic ice melts and rainfall intensifies, a large amount of fresh water flows into the North Atlantic, destroying the Mexican warm current. Once the Mexican warm current is cut off, the temperature in northwest Europe will drop by as much as 5-8 degrees, which may lead to a new ice age! You must have seen the movie the day after tomorrow. The scene in the movie is just a true portrayal of our earth after hundreds of years: tornado, ice breaking, sharp drop in temperature, ice storm, freezing rain, earthquake, flood, tsunami... This is not a crazy fantasy. If human beings do not stop destroying the environment, it will become a reality! Global warming is not only a hot weather, but also a lot of negative effects
in order to save the earth, we should try our best to: do not turn on the air conditioner, use recycled environmental protection paper, abandon meat (steak) food (cow digestion contains nitrous oxide, if you become a vegetarian, the annual carbon dioxide emissions will be reced by 1.5 tons!) Do not use plastic bags, take the bus... Every bit of life. In fact, environmental protection is not difficult. As long as you support environmental protection, it is your best gift to the planet. It doesn't need too much words. As long as everyone takes action, it will be a powerful force! Today, Japan, Britain, the United States and other countries have taken action. Although we have taken action, it is not enough for a great country with a population of 1.3 billion
therefore, global warming is the only way for all mankind to save the earth. Some people may say: can we not migrate to other planets? The answer is yes, but how many people can it hold? Some people say: the funds to control the greenhouse effect are too large, which is a sky high price for finance. However, if we keep procrastinating, the final result will be that our earth is beyond recognition, not to mention finance, even our own life is hard to protect! Therefore, environmental protection should not only stay in words, but should really be paid with action!
