Bitcoin mining accepted
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
this depends on the CPU computing time of your computer, and on your network speed. If you use an ordinary home computer or a personal mobile phone. You don't have to get a bitcoin a year
unless there are more powerful mining machines. Of course, it will cost more. Unless you don't invest in mining machines, you invest in illegal software. Let these illegal software invade other people's computers and mobile phones. Other people's computers and mobile phones do a lot of bitcoin computing and mining. In this way, the cost of mining machine, electricity, flow, heat dissipation and so on are saved. But we need to know that this is a violation of national laws. This will also allow other people's mobile phones to carry out a lot of calculations after power on, encroach on other people's memory, and make other people's mobile phones scrapped earlier< br />
Bitcoin is actually a virtual currency. When bitcoin first appeared, if you want to get bitcoin, you have to get bitcoin through mining. Therefore, bitcoin mining appeared. But bitcoin mining is more and more difficult, so it is very difficult to get bitcoin now
so now many people use Haru miner digs Ethereum, Monroe and other virtual coins. Most importantly, BTC can be directly equivalent in the end
Recently, the price of bitcoin continued to rise, reaching a maximum of US $41000. According to Mr. Liu, the manager of the mine, recently some customers have asked for additional orders, but the output of the mining machinery manufacturers is insufficient and they can't get a large number of mining machinery. Now they have to wait five months or more. Most of his customers have increased their positions in the middle of this year. At present, the prices of mainstream mining machines vary from 30000 to 60000, Mining takes about 12 months to recover the cost
therefore, if people really have mining ideas, they should not be dazzled by the impulse of the moment, and they should try to do it slowly. Today, the price of bitcoin continues to rise, largely because many mainstream investment institutions or investors begin to be interested in digital assets and begin to hoard bitcoin
bitcoin investment has great risks, the phenomenon of sharp rise and fall is not uncommon, and there are not a few people who have lost all their money. Therefore, it is not advisable to follow blindly and keep calm in investment
{rrrrrrr}
extended data
bitcoin plummeted by more than 10%:
earlier on January 11, bitcoin once fell to $37000 / piece, the lowest to $35141, and the biggest drop in the day was more than 10%. According to the data of bitcoin home.com, the amount of burst positions in the past 24 hours reached US $1.165 billion (about RMB 7.530 billion), and a total of 115138 people burst positions within 24 hours
for the sudden drop, some netizens said: "what should come will come.". Cautious investors said that such a high position, I first clearance, short about
in the very early days, when the computing power of bitcoin was very low, the computer could also carry out a lot of calculations according to the algorithm to "mine" bitcoin
when users "mine" bitcoin, they need to search for 64 bit numbers by computer, and then compete with other gold miners by repeatedly solving puzzles to provide the required numbers for the bitcoin network. If the user's computer successfully creates a group of numbers, they will get the bitcoin awarded by the block. However, e to the rising value of bitcoin, the number of users of bitcoin mining is very large. There are millions of professional mining machines mining at the same time, and the output of bitcoin is very limited every 10 minutes. As a result, tens of millions of people scramble for a block. Therefore, if you use personal computers to mine alone, you may not be able to grab a block in a whole year, People came up with a method of group mining, so the mining pool was born. There are a lot of users who play after mining
I hope you will adopt it.
bookkeeping
because bookkeeping is a reward, each time you can add a certain number of bitcoin for yourself, so everyone is competing for bookkeeping, which of course leads to a problem: when there is inconsistency in bookkeeping, the system introces workload proof to solve the problem, and the rules are as follows:
1. In a period of time, only one person can succeed in bookkeeping
2. Obtain the unique bookkeeping right by solving the cryptography problem
3. Other nodes the bookkeeping results
but before the workload proof, The accounting node will do the following preparatory work:
1. Collect the original transaction information that has not been recorded in the broadcast
2. Check whether the payment address in each transaction information has enough balance
3. Verify whether the transaction has the correct signature
4. Package and record the verified transaction information
5. Add a reward transaction: add 12.5 to your address Bitcoin
if you succeed in competing for bookkeeping rights, you can get a reward of 12.5 bitcoin
workload proof
the hash value of the previous block and the current account page information will be hashed together as the original information in each bookkeeping. In order to ensure that only one person can keep accounts around 10 minutes, we have to improve the difficulty of keeping accounts. The results of hash must start with several zeros. In order to satisfy the condition, hash is to introce a random number variable
denoted by pseudo code:
1. Hash (last hash value, transaction record set) = 456635bcd
2. Hash (last hash value, transaction record set, random number) = 0000afd635bcd
if you change part of the original information of hash, the hash value will also change continuously. Therefore, when you run hash, the value of random number will change continuously, A random number can always be found so that the result of hash starts with several zeros. The node that finds the random number first obtains the unique bookkeeping right
verification
after the node successfully finds the hash value, it will broadcast and package the block to the whole network immediately, and the node of the network will verify it after receiving the broadcast. If the verification is passed, it indicates that a node has successfully decrypted, it will not compete for the current block, but will choose to accept the block and record it in its own account book for the next round of competitive guessing. Only the fastest decrypted block in the network will be added to the ledger, and other nodes will to ensure the uniqueness of the whole ledger
If a node has cheating behavior, it will cause the node of the network to fail the verification, give up its packaged block directly, and cannot be recorded in the general ledger, then the consumption cost of the cheating node will be in vain. Therefore, miners consciously abide by the consensus protocol of bitcoin system, and ensure the security of the whole system
it's like you go to the construction site to move bricks. After moving bricks for one day, the contractor asks you how can you prove that you move bricks for one day?
The global epidemic has led to the regression of the real economy, while the virtual currency economy has entered a new stage of development< as the world's first cryptocurrency & mdash& mdash; Bitcoin has risen by more than 250%, from the lowest $3000 to today's $58000, which can be described as a rising tide. With the continuous improvement of virtual currency income, bitcoin's mining facilities also follow; Red & quot; I got up
as the future monetary system, bitcoin is decentralized. It's not a belief of blockchain mechanism. Due to the data leakage and privacy security problems caused by the current social centralization, it's difficult to guarantee. So many followers of bitcoin think that bitcoin is a consensus, which brings convenience to their life. But this belief has brought the cost of global environmental pollution, which is not optimistic by people
