Having a mine at home means bitcoin
bitcoin mining is a process that uses computer hardware to calculate the location of bitcoin and obtain it
mining is an incentive process to record data in the bitcoin system. In the bitcoin system, indivial users have the right to pack blocks after calculating a specific hash value by using CPU or GPU to hash
and in order to reward this user for packing blocks, the system will give a certain amount of bitcoin as reward. Because this process is very similar to "mining" in real life, most people call this process mining. In addition to bitcoin, other electronic virtual currencies can also be obtained through mining rewards, such as Ethereum, Monroe and so on
extended data:
mining risk:
1, currency security
the withdrawal of bitcoin requires hundreds of keys, and most people will record this long string of numbers on the computer, but frequent problems such as hard disk damage will make the key permanently lost, which also leads to the loss of bitcoin
2, system risk
system risk is very common in bitcoin, and the most common one is bifurcation. Bifurcation will lead to a drop in currency price and a sharp drop in mining income. However, many cases show that the forking will benefit the miners, and the forked competitive currency also needs the miners' computing power to complete the minting and trading process. In order to win more miners, the competitive currency will provide more block rewards and handling charges to attract miners. Risk makes miners
Bitcoin mining is a process of using computer hardware to calculate transaction confirmation and improve security. Bitcoin is a reward for miners to calculate and confirm
bitcoin also has a hype mode. Similar to bitcoin, there are also flow ores. Flow ores also have ways of trading and speculation, but the mining principle of flow ores is different from bitcoin. Flow ores mainly collect the idle bandwidth of miners and give them rewards
in fact, the blockchain technology adopted by bitcoin is more valuable than itself. This is a new way of information storage. The data is stored in all devices connected to the network. When new devices join, the information will be updated automatically, and all devices have the right to read the information
to understand the significance of bitcoin from the perspective of currency, we need to understand the currency itself first, and then compare it with the characteristics of bitcoin. After comparison, I think that bitcoin is a very high-quality currency, but some people don't think it is. They mainly question the formation mechanism of bitcoin and the lack of national credit as guarantee. They think its foundation is relatively weak
at present, there are quite a lot of arguments about bitcoin in academic circles. For example, if the total amount of bitcoin is certain, then whether it will cause deflation or inflation has different views. I think it's deflation, and the value of bitcoin will be higher and higher
at present, bitcoin still means a little bit of a safe haven currency. When the news of brexit came out, the transaction price of bitcoin rose by 20% - 30% to about 4500 yuan / piece
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
the concept of bitcoin was first proposed by Nakamoto in 2009. Bitcoin, also known as bitcoin, is an open source software designed and released according to the idea of Nakamoto Tsung, and a P2P network built on it. Unlike most currencies, bitcoin does not rely on a specific central issuing institution. It uses distributed databases throughout the P2P network nodes to record currency transactions, and uses cryptography design to ensure the security of all aspects of currency circulation
Mining bitcoin is also called mining. Starting from the essence of bitcoin, the essence of bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution is one of the infinite (in fact, bitcoin is finite) solutions that can be obtained from the equations. Every particular solution can solve the equation and is unique
in the metaphor of RMB, bitcoin is the serial number of RMB. If you know the serial number of a note, you have the note. The process of mining is to constantly seek the special solution of this equation system through a huge amount of calculation. This equation system is designed to have only 21 million special solutions, so the upper limit of bitcoin is 21 million
bitcoin: also known as "bitcoin", is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats, equipment, etc. in online games. Internet users can also use bitcoin to buy real goods
extended data:
shortcomings
first, the vulnerability of trading platform. The bitcoin network is robust, but the bitcoin trading platform is fragile. Trading platform is usually a website, which will be attacked by hackers or shut down by competent authorities
Second, the transaction confirmation time is long. When bitcoin wallet is first installed, it will consume a lot of time to download historical transaction data blocks. While bitcoin transaction, in order to confirm the accuracy of data, it will take some time to interact with P2P network, and the transaction will be completed only after the whole network is confirmed Thirdly, the price fluctuates greatly. Due to the intervention of a large number of speculators, the price of bitcoin for cash fluctuates like a roller coaster. Making bitcoin more suitable for speculation rather than anonymous trading Fourthly, the public did not understand the principle, and the traditional financial practitioners resisted. Active netizens understand the principle of P2P network and know that bitcoin has no legal person to manipulate and control. But the public doesn't understand, and many people can't even tell the difference between bitcoin and q-coin“ "No issuer" is the advantage of bitcoin, but in the view of traditional financial practitioners, "no issuer" currency is worthless1. I now have a 100 yuan personal name coin in my hand Bitcoin)
2.. Who cares about the official account? But you need to guess the number of the money in the comments Mining, random filling, numerical solution)
try your best to guess, and you get 100 yuan in full - personal mining
pay money to gather some people to guess together - mining field
gather people you don't know to guess together, and allocate the 100 yuan in proportion through the number of guesses -
the above is a simple example of analogy, of course, You followed and guessed the number of 100 yuan in my pocket, I promise you
so what's going on with bitcoin mining

when Zhang San wants to transfer 1000 yuan to Li Si's B account through a account: ① Zhang San roars: attention, I use a account to transfer 1000 yuan to Li Si's B account. ② The villagers near Zhang San listened to Zhang San's voice and checked whether Zhang San's a account had enough balance. ③ After passing the inspection, the villagers write on their account books: account a transfers 1000 yuan to account B, and modify the balance: account a balance = 3000-1000 = 2000 yuan, account B balance = 2000 + 1000 = 3000 yuan. ④ The villagers near Zhang San told the villagers far away about the transfer, and passed it on until everyone knew about the transfer, so as to ensure the consistency of everyone's account books. Smart if you must have found out, in step 2, if Zhang San roars, and the villagers nearby pretend not to hear him, and do not check the account, then the system will stop working? In order to solve this problem, the village decided after discussion that whoever first confirmed Zhang San's voice would get 500 yuan. So everyone put up their ears and monitored every movement in the village. It's really a matter of grass and trees. Someone in the comment area asked, where did the 500 yuan come from? I would like to give a brief answer here. 1. On average, bitcoin generates a block every 10 minutes. The number of transactions that can be packaged in this block is limited. Let's count it as 800. However, absenteeism will not give you a package deal and broadcast for no reason, so you need to charge a handling fee. Moreover, because there are many people in the transaction, whose transaction to pack first also depends on the level of handling charges. So you can see that bitcoin is hot now, and the handling charges are going up. 2. We all know that the total number of bitcoin is 21 million, and the issuing mechanism is decreasing year by year. If absenteeism is the first one to successfully package this block and broadcast, and it is the longest chain, he will be rewarded. At present, there are only 12.5 bitcoins. It started with 50. It's decayed twice. Of course, there are small problems, such as why the longest chain is needed, how to determine the longest chain, and which chains will be abandoned? If you are interested, let's talk about it further. The above is the reward for absenteeism. Updated on December 8, 2017. In the world of bitcoin, one block is generated about every 10 minutes. All mining computers are trying to package the block and submit it, and the first person who successfully generates the block will get a bitcoin reward. Initially, bitcoin rewards of 50 bitcoins could be generated about every 10 minutes. But the payment is halved every four years, and now the bitcoin network can generate 25 bitcoins every 10 minutes. Well, then the story above tells that Zhang San's roar shocked the whole village, and everyone said that they were the first to hear Zhang San's voice. Who should I give the 500 yuan to? So the village discussed the new regulations, and needed evidence to prove that it was Zhang San's voice. Zhang San's cry contains specific sound data, which will be given to whoever breaks it first. In the bitcoin world, this is a new concept, consensus mechanism. Bitcoin decides the bookkeeping right through the consensus mechanism of workload proof. Generally speaking, the one who proves his workload is the biggest is responsible for bookkeeping. The amount of work is reflected by calculating the hash value of the bitcoin block header that meets a certain standard. The block header usually contains the hash value of the previous block, Merkle root, timestamp, difficulty target, and a filled random value. The node that tries to fight for the bookkeeping right is called mining node. The mining process is to find a random value that can fill the block head of this area, so that the hash value of the block head can meet a certain standard

bitcoin is a string of code generated by an open-source P2P software, which we call cryptocurrency, e-currency and so on. Bitcoin is proced by mining. Generally speaking, bitcoin mining is to use your hardware to calculate the mathematical problems of sh265 algorithm, confirm network transactions, and ensure the security of the whole network system. As a reward, bitcoin system will give a certain amount of bitcoin reward according to the amount of computing power contributed by miners

mining is bitcoin. Bitcoin will be generated several times every other period of time, and whoever grabs it will own it. The computer connected to the bitcoin system is the tool "miner" for grabbing bitcoin. As for the issue of national recognition of bitcoin, simply speaking, it depends on the possible impact on the country< br />
after the iron ore is g, it is ignited in the refining furnace and processed into metal ingot. Before the instrial furnace is proced, we can only use the refining furnace to burn iron, and we can do more to speed up the efficiency. Iron ore is mainly distributed near the volcano and the northern snow peak
there is a great demand for iron ore in the later stage. It is recommended to use the large-scale steel-making method, We can also directly move our home to the volcano,
1. We first tame a Jialong, and then use an eagle to carry it to the top of the volcano. There is no living creature on the top of the volcano, and there is a lot of iron ore. this Jialong stayed here as a slave, and it was left here before the iron ore was emptied
2. In the second step, we use Jialong to collect iron ore and stone. We take part of our own materials and use enough stones to build a refining furnace on the top of the mountain to load iron. Then we get a grinder to throw the collected flint and stone into it to make igniting powder
3. The ignition powder can be directly used as fuel to drive the combustion of the refining furnace. We use the existing resources at the top of the mountain to forge directly on it, and then use the eagle to transport the iron ingot home. Two pieces of iron ore can be refined into one piece of iron ingot, and the weight can be reced by half, so we don't need to transport it home for refining
PS: ring this period, we can tame more eagles and transport materials together. If there is Fengshen, the efficiency will be higher! Remember to continue to expand our refining furnace, burning together, the efficiency is fast.
