Bitcoin mining machine operation attenuation
behind the scenes, the entire bitcoin network shares a public ledger called "blockchain.". This general ledger contains every transaction processed, so that the user's computer can verify the validity of each transaction. The authenticity of each transaction is protected by the electronic signature corresponding to the sending address, which enables users to have complete control over the bitcoin transferred out from their own bitcoin address. In addition, anyone can use the computing power of specialized hardware to process transactions and get a bitcoin reward for it. This service is often referred to as "mining."
bitcoin mining has gone through three stages of development. When bitcoin was just born, the price of bitcoin was very low. People just took bitcoin as a game and used their ordinary computers to mine. However, in 2012, with the rise of bitcoin price, people found that the mining speed of graphics cards was fast, so, People began to buy a large number of graphics cards and assemble them for mining, commonly known as "burning graphics cards"; The third stage is the well-known ASIC miner mining. Since Avalon proced the world's first ASIC bitcoin miner, bitcoin mining has been completely subverted, and mining has become a special professional thing.
you need to have specific questions and algorithms to
change the bitcoin miner into a decryption device
. If these questions are not clear, they cannot be answered
2020 is the first year of digital currency proction rection. Most currencies will achieve the first proction rection this year, while bitcoin will usher in the third proction rection cycle. And the market is generally high on the halving market, it is expected that this year will usher in a wave of bull market, and the logic behind it is very clear. From the perspective of historical experience, this has already formed a more extensive "consensus" in the circle of cryptocurrency
secondly, bitcoin, known as "digital gold", is recognized by more and more funds for its risk aversion, which indirectly pushes up its price. At present, in addition to bitcoin, which has the most influence, BCH, BSV, etc, dash and other currencies are the most concerned. Dozens of counterfeit currencies have chosen to be halved in 2020. Therefore, 2020 is also known as the first year of halving
what is half bitcoin
bitcoin halving means that the reward for procing new blocks is halved about every four years. This means that after halving, the corresponding bitcoin reward for each block proced is only half of the reward before halving. At present, bitcoin has been halved twice, respectively in November 2012 and July 2016. The third half of bitcoin is expected to take place on May 13, 2020. By that time, bitcoin will be halved from 12.5 blocks to 6.25 blocks
half block reward means that it will take longer for all bitcoins to enter circulation, but it also means that mining will proce fewer and fewer new bitcoins. Moreover, e to its limited supply and increased mining difficulty, its scarcity attribute becomes more and more obvious, and scarcity will directly enhance the value. As the saying goes, scarcity is more expensive! For bitcoin, there is no doubt that this is a very big advantage
buying bitcoin in 2020 is better than buying bitcoin ETF fund
3, bitcoin current price 10000x4 = US $40000 (expected price after this year's proction rection)
in this period, the return comparison between holding spot and ETF fund is as follows:
1, buying spot holding, earning three times
2, buying ETF fund, Up to 15 times (intelligent position adjustment + fund compound interest calculation)
there is no doubt that bitcoin ETF launched by bitoffer is the best investment choice
1. Mining can not only proce bitcoin, but also guarantee transaction information
similarly, a mathematical system contains 21 million mathematical problems, so we need to constantly seek the special solution of each mathematical problem through a huge amount of calculation. In addition, the special solution is unique
mining can not only increase the supply of bitcoin money, but also protect the security of bitcoin transactions and prevent fraulent transactions. In terms of process, bitcoin network is a point-to-point payment system, and anyone can trade through the transaction program
in order to ensure that the transaction process is truthfully recorded, the role of "miner" is required to be responsible for recording bitcoin transaction information. The time interval is 10 minutes. The best recorded transaction records among miners will be packaged and stored in a new block, and the corresponding miners will also receive a certain amount of bitcoin rewards
2. The mining process is extremely complex, which is beyond human power
the specific process is as follows. When a miner listens to the transaction, he will first verify the transaction information. The verified transactions will be recorded by miners and stored in their own database. There may be thousands of miners in the world doing the same thing, but every ten minutes, only one miner has the right to create a new block, so that the transaction information recorded by himself can be recognized and stored permanently
next, miners need to fight for the right to keep accounts. This is a competition of computing power. The core of this competition is to use computers to complete a large number of calculation tasks and find a super difficult random number. This random number is the special solution of the equation mentioned in the first paragraph. The miner who calculates the correct random number first wins. According to the rules of the game, the probability of a miner getting the accounting right is directly proportional to the proportion of his computing power in the total computing power of the whole network. In other words, the probability of finding the random number is equivalent to throwing out 100 million dice, and the total number of dice is less than 150 million. Therefore, mining requires a large number of computers, installation of specific algorithm software, repeated operation day and night, not human
3. Bitcoin mining is actually "villagers' bookkeeping"
maybe some netizens still don't understand, let's take an example. In a village, the villagers often borrow money from each other, even if they write a written document, there is a risk of default. Then, every time there is a loan behavior in the village, we will use the village trumpet to inform everyone that all the villagers (miners) will record all the transaction records in their own account books.
but bitcoin mining as an infrastructure, if bitcoin can continue to exist, although the income of mining is reced, for the security of the whole bitcoin network system, some big bitcoin companies may invest in mining to maintain the security of bitcoin network system. In addition, the future of bitcoin will become more clear and bright. Bitcoin's computing power will not decrease, but will increase.
Tencent credit score: the lowest is 300 points, the highest can be 850 points< Zhima credit score: the lowest score is 300, the highest is 950.
the second difference: different scoring standards
Tencent credit score: the score is obtained through comprehensive evaluation of the five indexes of "performance, security, wealth, consumption and social interaction"
sesame credit score: mainly through the five dimensions of "performance ability, identity characteristics, behavior preference, interpersonal relationship and credit history"
the third difference: enjoy different rights and interests
at present, as Tencent credit score is still in the testing stage, the services it can enjoy are particularly limited, but comparatively speaking, sesame credit score has been developed for a period of time, with more complete functions
Tencent credit score, the most anticipated is "micro particle loan", but for now, there is no correlation between Tencent credit score public test qualification and micro particle loan. Of course, it does not rule out the positive significance of Tencent credit score query to the opening of micro particle loan entrance.
In fact, the mining calculation of bitcoin is to do math problems together. The problem stem is the transaction that needs to be recorded. By doing the problem, everyone grabs the bookkeeping right, and the miners can get system rewards and transaction fees. The feature of sha256 algorithm used in bitcoin is that it is easy to verify the known answers correctly, but it is very troublesome to get the answers, and it needs to try one by one. The miner who got the answer first was recognized by everyone as having snatched the right to keep accounts, and the reward was given to him. Let's continue to grab the bookkeeping right of the next question. In short, the significance of these calculations is only to ensure the stability and safety of the whole system, and there is no more significance
it is not comprehensive to regard bitcoin as a by-proct of computing. The generation and issuance of bitcoin, all the transactions and circulation in the bitcoin chain, and the stability of the bitcoin system are the purpose of computing and are integrated. Of course, in addition to maintaining the system, it does not proce other value and procts. This is also a black spot where bitcoin is accused of not being environmentally friendly and wasting resources. In general, bitcoin, as a milestone blockchain digital currency, is e to the huge value of a large amount of computing power investment and user trust. There is no doubt about that
