Function of mining graphics card adapter

1.

Generally, there are professional graphics cards to mine, and the mine is actually bitcoin. Users download the mining software from the computer and then run a specific algorithm. After communicating with the remote server, they can get the corresponding bitcoin. Most of them work by burning the graphics card, so the power consumption is large

the graphics cards and mine cards are usually ATI chips. The bitcoin market is not good, so the miners take out their mining cards and sell them as second-hand

what is mining

to put it simply, mining is to use the chip to perform a calculation related to the random number, and get the answer in exchange for a virtual coin. 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. It's possible that one chip will find the answer in the next second, or ten chips won't find the answer in a week. The more chips compute at the same time, the easier it is to find the answer, and the mining machine with built-in multi chips appears. And a number of mining machines to form a "mine" at the same time mining is to improve efficiency. In the mine pool, multiple "self-employed" join an organization to mine together. No matter who finds the answer and digs out the virtual coin, everyone gets the corresponding reward according to the calculation ability of contribution. This way can make the income of "self-employed" more stable

relationship between mining and graphics card

the stronger the computing power of ant miner, the easier it is to dig out virtual coins. Accordingly, when the more virtual coins are g out, the difficulty of mining will be increased accordingly, so as to control the yield of virtual coins. The virtual currency is not unlimited. The total number of bitcoin is 84 million

Mining, in fact, is to use graphics card to dig bitcoin

bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

Graphics card mining is a process of increasing the bitcoin money supply

the reason why the graphics card is used is that mining is actually a competition of performance and equipment. The mining machine is composed of graphics card array. With dozens or even hundreds of graphics cards, the cost of hardware and other costs is very high, and there is a considerable expenditure in mining

computers have professional mining chips, and most of them work by installing a large number of graphics cards, which consumes a lot of power. One of the ways to get bitcoin is to download mining software and then run specific algorithm to communicate with remote server to get corresponding bitcoin

extended data

bitcoin does not rely on the issuance of specific monetary institutions, and is generated through a large number of calculations of specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction

the bitcoin system is composed of users (users control the wallet through the key), transactions (transactions will be broadcast to the whole bitcoin network) and miners (the blockchain is generated by competitive computing to reach a consensus at each node, and the blockchain is a distributed public authoritative account book, including all transactions in the bitcoin network)

bitcoin miners manage the bitcoin network by solving the problem of workload proof mechanism with certain workload - confirming transactions and preventing double payment. Because hash operation is irreversible, it is very difficult to find the random adjustment number of matching requirements, which requires a continuous trial and error process that can predict the total number of times

when a node finds the solution matching the requirements, it can broadcast its results to the whole network. Other nodes can receive the new data block and check whether it matches the rule. If other nodes find that they really meet the requirements (the operation target required by bitcoin) by calculating the hash value, then the data block is valid, and other nodes will accept the data block

4. Graphics card uses GPU for general purpose calculation. So it can stack hundreds of stream processors awesome. Each stream processor is like a small CPU. Although its ability to run complex programs is far from the power of CPU, it can not support many processors, so the actual performance, especially the single precision floating point performance, is much stronger than that of CPU. The actions in bitcoin can be regarded as the use of graphics card to do continuous general computing, and the computational complexity is relatively low and quite repetitive. The stream processor used by graphics card is just suitable for such an algorithm.

The mine card of graphics card is the graphics card used by bitcoin mining machine

Mining card is a graphics card that is specially used for general calculation to earn network currency "bitcoin". Bitcoin can be proced with specific programs, and then sold to people in need to be able to exchange real money, or mining for short

because this program needs a lot of repeated calculations, it is more efficient to use a card with more sp. Because of the full load operation all year round, there are many uncertain factors in the mining card

extended data:

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it is only hd6770, the computing power after "group" 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

in fact, there are many kinds of mining devices. Guiminer, which is small and easy to use, is recommended. It can support CPU, oepncl, CUDA and other computing modes

in this way, devices including CPU and graphics card can achieve the maximum performance, and then acquire bitcoin more quickly

6. The information transmission of the blockchain itself may be false
1. The provincial characteristics of the blockchain, once included in the block, are irreversible and can not be tampered with, and the information is true and effective, but there is only one case that is false, that is, the information written in the first attempt is false, resulting in the false information stored in the block
2, Basically, it's the application side of the technology

7. The stone of sages will not appear until the tools are blessed, so you can't find the stone of sages

the stone of sages appears in the spring mine
60102123152155171190,
202222231 ~ 255 layers in the stone

there are cursed tools in the 29th / 39 / 49 / 59 / 69 / 79 layer of Lake mine, You go to the Lake mine to dig it first

curse props turn to blessing
sickle: the sickle of curse is equipped for 10 consecutive days, and you can't go to church to get it in the middle
hoe: go to church 10 times to "remove the curse props" 1 time 1000g
Axe: the axe of curse is used 255 times, and you don't need to buckle your physical strength ring the festival activities<
hammer: cursed hammer is equipped for 10 days in a row
sprinkler: go to church 10 times to "remove cursed props" 1 time 1000g
fishing rod: cursed fishing rod is used 255 times

all farm tools must be raised to blessing before they can dig the sage's stone

8. It is recommended not to operate. Most of the digital currency platforms are illegal pyramid schemes. If they are inced to speculate in money, they can only be recovered from the homepage.
