What's the use of blockchain miner computing power

1. bitcoin is a digital currency based on a specific algorithm. < blockquote >

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

2. mining is a way of exchanging time for space and buying currency at fixed cost. The growth of computing power, the rise and fall of currency price and the update of equipment will be in a dynamic balance. As long as you are optimistic about the blockchain and feel that you don't have the ability to stir up money with high price and low price, investment and mining will be a good choice for blockchain investment. Can contact NB cloud mining, mining agent operation, more professional, every day there are benefits.

Suppose you understand the blockchain. To put it simply, the blockchain generates a new block every ten minutes to store all the transaction information in the blockchain. This block is equivalent to a network account book, which correctly time stamps all the transactions of the whole network in the past ten minutes. The question is who will build it? The "miner" on the blockchain is to compete for the bookkeeping right of a block in the past ten minutes. The rule of competition is to solve the sha256 problem while correctly bookkeeping. Who can prove that his computer has the fastest computing power can compete for the legal bookkeeping right of the block in the past ten minutes. This is the "mining" process. In the bitcoin blockchain, miners who dig mines can get certain bitcoin rewards. Therefore, miner's more essential function is "bookkeeper"

in his bitcoin white paper, Nakamoto describes in detail the process of establishing the credit system:

Step 1: in order to make the whole network recognize effective, every transaction must be broadcast to each node (node: miner)

Step 2: each miner node should correctly stamp each transaction in the ten minutes and record it in that block

Step 3: each miner node should compete for the legal bookkeeping right of this 10 minute block by solving the sha256 problem, and strive for the reward of 25 bitcoins (50 bitcoins every 10 minutes in the first four years, decreasing by half every four years)

Step 4: if a miner node solves the ten minute sha256 problem, TA will publish all the time stamped transactions recorded in the ten minute block of TA to the whole network, which will be checked by other miner nodes in the whole network

Step 5: other miners in the whole network check the correctness of the block's accounting (because they are also stamping the time stamp for accounting, but they do not compete for the legal block's accounting right, so there is no reward). If there is no error, they will compete for the next block after the legal block, thus forming a single block chain of legal accounting, That is the general ledger of bitcoin payment system - blockchain

generally speaking, each transaction must go through six block confirmations, that is, six ten minute bookkeeping, before it can be recognized as a legal transaction on the blockchain. The following is the accounting format of bitcoin:

so the so-called "bitcoin" is such a billing system: it includes the owner using the private key to make an electronic signature and pay to the next owner, and then the "miners" of the whole network stamp the account to form a blockchain Network)

if you want to learn more about blockchain information, it is recommended that you use Baijia, mustard circle and other popular B circle media. The amount and richness of information are more and better than those on the general network.

4. Existence is reasonable. Any instry can make money. In recent years, blockchain has been very popular, and there is still a lot to be done. Now I use ewacould mining machine, which is quite good

5. Not long after I started mining, I only used one kind of miner, gym intelligent miner, which was recommended by my friend. He has been mining for a long time and said that the indicators of this miner are perfect, and the computing power of gym titanium crystal chip can absolutely keep up.

6. "Mining" in the blockchain is the process of bookkeeping. You can purchase computing power equipment, that is, "mining machine", to "mine" and get bookkeeping rewards
however, with the increasingly fierce competition in bookkeeping and the graal rise of dpos, ordinary computing power equipment has been unable to meet the needs of mining
it is necessary to purchase more professional mining machines or join large mines. Therefore, the threshold of mining is slightly higher
where there is demand, there is market
e to the increasing market demand for professional mining machinery, more and more chip enterprises increase investment in chip R & D, and start to develop mining machinery with higher computing power and lower energy consumption, so as to earn profits
when the currency price rose sharply in 2017, this kind of mining machinery was in short supply
as the level of computing power in the whole network is getting higher and higher, it is difficult for a single miner to seize the bookkeeping right and obtain bookkeeping rewards. Therefore, the way of combining a small amount of computing power and joint operation arises at the historic moment to improve the competitiveness of bookkeeping
the website established in this way is called "mine pool"
the profit model of the mine pool is to charge the handling charge. The more people participate in the mine pool, the higher the proportion of handling charge, the higher the income of the mine pool company
blockchain is the core supporting technology of digital cryptocurrency system represented by bitcoin. The core advantage of blockchain technology is decentralization. It can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the common high cost, low cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

7. 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" and "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 miner as the guardian of blockchain
with mining machines, 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. Oh, let's have a look.

8. How to say this? Now the mining machine is really not fragrant. Although only a few people know it, it's really unnecessary
