GPU computing power connected to mine pool
The first step in setting up mining equipment is to choose the right hardware. This article will focus on GPU (graphics card) mining, of course, you can use CPU or ASIC equipment mining. Amd graphics card architecture is very beneficial to mining. NVIDIA card is not suitable for mining because of its low hash rate. The best NVIDIA graphics cards are less than 0.5 megahash. Notebook Hardware mining is not as good as NVIDIA card, which is a bad option for mining. You need to use a desktop system for mining. There is a desktop system to ensure adequate cooling of the hardware
the graphics card or card needs to be able to match the motherboard, and the power supply must have enough PCI-E connectors. Before determining the graphics card, pay attention to these. In order for the system to cool down sufficiently, you need to remove the cover of the chassis in order to get better heat dissipation. This is what people call "open air rig.". If you can aim the system at a fan or air conditioner, you can make the device cooler when it's running, thus extending its life and keeping it efficient
Mine pool refers to:
as the computing level of the whole bitcoin network continues to rise exponentially, a single device or a small amount of computing power can not get the block reward provided by the bitcoin network on the bitcoin network
after the computing power of the whole network has been improved to a certain extent, the low probability of getting rewards has prompted some geeks on "bitcoin talk" to develop a method that can combine a small amount of computing power and operate jointly, and the website established in this way is called "mine pool"
extended data:
the existence of the mine pool reces the difficulty of bitcoin and other virtual digital currency mining, reces the mining threshold, and truly realizes the bitcoin mining concept that everyone can participate in
but its disadvantages are also very obvious, because computing power is connected to the mine pool. As a mine pool, it will have huge computing power resources. In the bitcoin world, computing power represents the bookkeeping right, and computing power is everything. If the computing power of a single mine pool reaches more than 50%, it will be easy to launch 51% attacks against virtual digital currencies such as bitcoin, The consequences are very terrible:
the mine pool can make the mine pool with 49% of the remaining computing power have no harvest, instantly quit the competition and go bankrupt. The mine pool's computing power exceeds 50%. If 51% attack is launched, it will easily occupy all the effective computing power of the whole network
After the computing power of the whole network has been improved to a certain extent, the probability of getting rewards is too low, so that some geeks on "bitcoin talk" can develop a method that can combine a small amount of computing power and operate jointly, and use this method to build websites
in this mechanism, no matter how much computing power an indivial miner can use, as long as he participates in mining activities by joining the mine pool, no matter whether he has successfully mined effective data blocks, he can get a small amount of bitcoin reward through his contribution to the mine pool, that is to say, many people cooperate in mining, and the bitcoin reward is shared by many people according to their contribution
as of January 2019, the top five bitcoin pools in global computing power are btc.com, pool, antpool, flush pool, and f2pool. At present, about 70% of global computing power is in the hands of Chinese miners
extended data:
handling charge:
bitcoin miners will charge a small amount of fees for most transactions, the main purpose of which is to prevent people from sending a large number of boring small transactions and wasting network resources. At present, most of the handling charges for each transaction are & T 3647; 0.0001/kb (0.0001btc / KB). In fact, after 0.9.0, the default handling charge will be reced to & 3647; 0.00001/KB(0.00001 btc/KB)
because the amount of data occupied by most transactions is less than 1 kilobyte, generally speaking, the amount of data is less than 3647; 0.00001 (0.00001 BTC / KB) is enough. At the same time, in the future, when the bitcoin block rewards are less, the service charge will become the main source of miners' income, and the service charge of bitcoin will be related to the number of bytes occupied by the transaction
at present, the calculation standard of service charge in bitcoin system is not mandatory, so users can not give any service charge when the transaction is in progress
however, most miners usually give priority to the transaction with higher handling charges when building data blocks, so that they can get higher remuneration when mining is successful. Therefore, the transaction without any handling charges may take a long time to be processed and incorporated into the blockchain
in addition, e to the block capacity limit of 1MB and the recent increase in bitcoin transaction volume, the handling charges have increased significantly, and the waiting time for the transaction to be confirmed has also become much longer

the air is dirty and the bath is dirty
in a bath center located in Taihang District of Taiyuan City, a bad smell comes from the bathroom. It turns out that the bathroom and toilet are connected as a whole. In addition, in winter, the windows are closed and the air is not circulating, so the air in the bathroom is dirty. However, what is even more unacceptable is that the water in this bathing center is cool and hot“ It's strange that you don't catch a cold when you wash it like this. " Said a customer who came to take a bath. Take another look at the water in the bath. On it, there are still oil stains left by the bather after washing. However, the bath worker still takes the dirty water to wash the customer's body. A customer who asked for a bath could not help but ask: "can this kind of cleaning be cleaned?"
low price and equipment in disrepair
the price tag of the dormitory bathhouse of the weaving factory located in Changfeng street is: 3 yuan for bathing + sauna, 3 yuan for rubbing bath and 8 yuan for massage. Such a low price will naturally attract many customers. Entering the bathroom, the scene is disappointing. Due to the long-term corrosion of humid air and water, the wood board in the steaming room has been moldy. In the corner of the room, there are electric stoves piled with hot coal and exposed red wires. However, only a few thin wooden blocks are used to block the stove emitting high temperature. Once someone accidentally touches it, it is easy to be scalded
more than one customer shared a towel
in the process of taking a bath, one out of every three people asked to take a bath. However, the reporter noticed that every customer was given the same towel by the washman. When the reporter said whether it was sanitary or not, the washman had his own understanding: "Oh, who still uses my towel now? It's so dirty. People take it with them. " At this time, the customer said to the bath worker, "can you give me some soap?" The bath worker took up the customer's soap and put it on the towel, daubed it all over the customer's body, then opened his mouth and said, "one piece." At this point, the customer realized that the original 3 yuan only for "rubbing bath".
the second is the studio of the enterprise company. The development of 5g software requires high-performance computing and requires high computing power of GPU. You can choose to rent the physical machine of GPU server. If there is such business in the market, at least Shaolin haitiancheng is operating it
personal opinion, if there is misunderstanding, please don't blame me!!!
