What is blockchain mining machine
bitcoin is equivalent to digital gold. As a generally recognized equivalent, gold naturally has monetary properties and has been regarded as a kind of currency since ancient times. Bitcoin was born in 2009 and created by a person named Nakamoto. As the earliest digital currency, it was worthless at the beginning of creation. Until 2017, the highest transaction price of bitcoin exceeded 30000 RMB. The reasons why bitcoin became a valuable digital currency are as follows:
first of all, it is like gold, as a natural mineral, The total amount of bitcoin is limited. Bitcoin can not be over issued according to its own algorithm, so there will be no rapid devaluation of currency e to excessive currency issuance. The number of bitcoin is controlled to no more than 21 million e to the algorithm, so it can not be issued in large quantities, so its value is guaranteed
Before specifically talking about what mining is, you need to know what blockchain is
to put it simply, blockchain is a new application mode integrating various computer technologies. Just treat it as a new technology. The network constructed by blockchain technology has the characteristics of "decentralization", "information tampering", "openness", "anonymity", "security and reliability". These technologies can be applied in many fields, in short, it is very powerful ~
miner, a simple understanding is a more advanced computer, miner is to contribute to the blockchain network, you can regard miners as the guardian of the blockchain
with mining machinery, the blockchain network can operate normally. These mining machines are constantly doing calculations to provide computing power for the blockchain network. When the mining machine makes the correct calculation, the whole blockchain network will reward the mining machine with the corresponding digital currency. This process is called mining
if you also want to make a "contribution" to the blockchain, you need to download the mining system to start, miracle Moore learn about it
code is not easy, hope to adopt, thank you!
In 2009, bencong invented bitcoin, and set that there are only 21 million bitcoins. By participating in the proction of blocks and providing proof of work (POW), he can get the reward of bitcoin network. This process is mining
the concept of "mining" comes from the existing concepts in our real economic life, such as gold mining and silver mining. Because minerals are valuable, it drives people to pay labor to dig
another important point of bitcoin mining is that the miners who participate in mining recognize the value of bitcoin, and some of them are willing to spend money in the bitcoin market. Therefore, the mining of bitcoin is meaningful

currency characteristics of bitcoin
1, decentralized
bitcoin is the first distributed virtual currency, and the whole network is composed of users without central bank. Decentralization is the guarantee of bitcoin's security and freedom
2, bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
3, exclusive ownership
controlling bitcoin requires a private key, which can be stored in any storage medium in isolation. No one can get it except the user himself
4, low transaction cost
bitcoin can be remitted free of charge, but in the end, about 1 bitfen transaction fee will be charged for each transaction to ensure faster transaction execution
5, no hidden cost
as a means of payment from a to B, bitcoin has no cumbersome limit of quota and proceres. If you know the other party's bitcoin address, you can pay
6, cross platform mining
users can explore the computing power of different hardware on many platforms
Bitcoin mining machine is a kind of computer used to earn bitcoin. This kind of computer generally has professional mining chips and works in the way of burning graphics card, which consumes a lot of power. It is one of the ways to get bitcoin that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server
mining is actually a competition of performance and equipment, and a competition of computing power among miners. Miners with more computing power are more likely to dig bitcoin. With the increase of computing power in the whole network, it is more and more difficult to dig bits with traditional devices (CPU, GPU). People have developed chips specially used for mining. Chip is the core part of mining machine. The process of chip operation will proce a lot of heat, in order to cool down, bitcoin miner is generally equipped with heat sink and fan
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
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
with the development of
blockchain,
digital currency
has been widely recognized, and more and more people are engaged in mining.

gym mining machine is recommended, with more advanced intelligent technology.
in a village, a spent 3000 yuan to buy a cow of B, how to record this account
so a and B found a mutual trusted C to record the account, but later a and C colluded and did not admit that a had bought B's cattle, so the deal became rough and disputes continued
later, B had another cow. Of course, B didn't sell it to a this time, because a had no credit, so he gave it to d. This time, instead of looking for witnesses, they went to the whole village to roar after the transaction. B said Wang Erhua paid 3000 yuan to buy a cow from me, d also went to the whole village to shout that I paid 3000 yuan to buy a cow from B, so there were many people in the village to record the transaction. In this way, there will be no bad debts, which is called decentralized and distributed accounting
here comes the problem
when you yell, are the villagers willing to charge for you, just because you have a big face
therefore, the first person to record accurately will get some bitcoin rewards
someone asked, what if two people finish the first record at the same time
in order to avoid this problem, it is necessary to set rules, for example, to answer a question first, or to record with feet, and it must be written in block letters. If you set a series of rules, there will not be many firsts
in the network, there are a lot of transactions going on every day, and there are also many people recording, and finally they get the reward of bitcoin. This process is the legendary mining
Mining requires a lot of equipment. We call these computer equipment mining machines
in this way, all the processes are in one system. The system will encapsulate the data every 10 minutes to form a box full of data, which we call blocks
with the continuous generation of blocks, they are linked together to form a blockchain.
NBA 2k17 is a basketball competitive game proced by visual concepts and released by 2K games. It was officially put on sale on September 20, 2016 and belongs to the 17th generation of NBA 2K series
NBA 2k17 will support HDR on Xbox one s, which makes NBA 2k17 the first Xbox one game to support this technology[ 2] In addition, the 1992 American basketball dream team will be included in the pre purchase bonus DLC
nowadays, virtual currency mainly refers to bitcoin, Leyte coin, doggy coin, Puyin, Ethereum and other mainstream digital cryptocurrency.
