How much income does bitcoin computer node have

1.

at present, the computing power of bitcoin in the whole network has reached 2.36 billion hash collisions per second, which is equivalent to the number of water droplets in more than 200000 50 meter long standard swimming pools. But even with such a large amount of computing power, it will take about 10 minutes to hit a hash value that meets the requirements

in 2012, bitcoin's output was halved for the first time, and in July 2016, bitcoin's output was halved for the second time. At present, 12.5 bitcoins are awarded for recording one page of account book. The next halving will take place around 2020, and the total number of bitcoins will not increase by 2040, with a total of 21 million. In other words, the difficulty of digging bitcoin is increasing, while the time required is increasing

2.

The total number of bitcoins is 21 million

in 2009, when bitcoin was born, block reward was 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. 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 about 21 million

monetary characteristics

1. Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom

2. Global circulation: 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: private key is needed to control bitcoin, 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 a transaction fee of about 1 bitfen 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

It's about 37 yuan

let me first introce the reward mechanism of bitcoin system

bitcoin can basically dig out a block every 10 minutes through system settings. The reward for each block is given to the miners who dig out the block. The miner who digs out the block is called the block miner. The block miner will record the legal transactions in the bitcoin network to the blockchain, so that the miner can receive the service charge for bookkeeping

there are two parts in the reward for the block Miner: one part is the reward given by the system, which is called coinbase reward (also known as system issuance reward), the other part is the reward for bookkeeping, which is called miner's fee. The coinbase reward started with 50 bitcoins. For every integral multiple of 210000 blocks, the coinbase reward will be halved. This is what we often hear about bitcoin mining reward halved in four years

at the present stage, the reward of coinbase is 12.5 bitcoins. At the present stage, the average transaction miner fee received by miners for digging out a block is about 0.1 bitcoin (not fixed), that is to say, the average reward received by miners for digging out a block is about 12.6 bitcoin

about 99% of miners' rewards come from the system's coinbase rewards. According to the bitcoin system, one block can be g out every 10 minutes on average. The number of new blocks that can be g out in one day is 144 (60 * 24 / 10 = 144). At present, the number of bitcoins that can be g out every day is 1800btc (144 * 12.5btc = 1800btc). With the miner's fee of about 0.1btc per block, the total reward for all miners in one day is about 1814.4btc

4. Erdos, 560 kilometers west of Beijing, is covered with hot waves and sandstorms. The gate is a dividing line, separating the two worlds. Outside the gate is a typical landscape of China's fourth tier Urban Development Zone, while inside the gate is a science fiction scene like the matrix. Eight large factories with blue roofs are juxtaposed. Tens of thousands of "mining machines" are flashing red and green light and roaring in the factory, making digital currency bitcoin for this "mine" day and night. This once the world's largest mine holds about 4% of the computing power (proction capacity) in the bitcoin world. During the peak period, it can dig out more than 100000 bitcoins a year, which is worth more than 3 billion RMB at the price of 30000 RMB in August 2017.
bitcoin was invented by "Zhongben cong" in 2009, Using the computing power of the chip, the boring and repetitive process of constantly "hash collision" in the blocks generated by the bitcoin system to win the bookkeeping right and thus obtain the system reward of bitcoin is vividly called "mining" in the bitcoin instry, and the professional staff engaged in this work are called "in the first few years of bitcoin operation, An ordinary laptop can play the role of "mining". However, the entry of Chinese miners has completely broken the balance of this situation. Relying on professional mining machines designed and made in China, they staged one after another bitcoin world computing power arms race, raising the threshold of "mining" tens of thousands of times

5.

You can't dig in a day. It takes 2000 years

the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

extended data:

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system

bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer

when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25

when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. 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 about 21 million

6. The nodes of bitcoin are software running on the computers of millions of bitcoin users, and millions of bitcoin nodes are interconnected to form a bitcoin network. Bitcoin node software usually includes the following functions:
1) wallet. It's used to store your bitcoin balance. In principle, as long as you have the private key of your own bitcoin address, you can use your own bitcoin
2) verify the transaction or payment. After receiving the transaction, the bitcoin node will use certain algorithms to verify the validity of a transaction. If you only change the balance of bitcoin in your computer, others will not recognize it. Similarly, your wallet will not recognize the transaction changed by others
3) mining. Core wallet can start mining function through a command to join the mining army, while SPV wallet usually can't (SPV is just passing by). However, it is not the node type that hinders home computer mining, but the rapid development of professional mining machines. Compared with ordinary computers, the computing power of ordinary computers is very small. Mining by ordinary computers is like digging your own backyard with a hoe, and then expecting to dig out gold
because of the demand of bitcoin users, bitcoin exchange was born. The exchange provides a place for centralized trading. People put money on the exchange, and the exchange will match and trade together, similar to stocks and securities. Therefore, banning exchanges does not mean banning bitcoin. Bitcoin network cannot be banned. Bitcoin is sent to the exchange's wallet, and all you see is a balance given to you by the exchange. In fact, you no longer have your own bitcoin. Bitcoin network is global. Where there is a network, there will be bitcoin. After the exchange closes, bitcoin will not disappear, but will return to where it should be.

7. You're talking about bitcoin hanging up, which means bitcoin mining. This was OK two years ago, but not now. At that time, there were few people who knew and played bitcoin, mainly gamers, geeks and digital currency enthusiasts. Mining was also very simple, and the computing power was very low. Ordinary computers could complete mining. However, with the rise of bitcoin price and the increase of attention, people began to look for faster ways to mine. Therefore, graphics card mining came to the stage of history, Some people buy a large number of graphics cards for mining, commonly known as burning graphics cards. Of course, there are also some people through the Trojan virus control a large number of computers for mining. But these were finally eliminated by history. In March 2013, the introction of ASIC mining machine into the market began to subvert bitcoin mining. With a large number of ASIC mining machine put into use, graphics card is graally eliminated. Now, of course, the profit of this kind of professional mining machine is very low, and it is almost difficult for retail investors to make profits. Now mining is fighting for electricity price and energy consumption. Mining is graally becoming centralized and computing power is concentrated.

8. 1. The government's regulatory attitude is unclear

it is understood that because bitcoin trading is not under the supervision system of banks, it is easy to be used in illegal activities, such as money laundering and drug purchase

at present, most countries, including China, have no clear attitude towards bitcoin regulation, except that Germany has made it clear that bitcoin is legalized and Canada has created the first bitcoin ATM. At present, there is still a lack of supervision on bitcoin in China, and the existing laws and regulations are not fully applicable to the supervision of bitcoin

e to the uncertainty of policy, some people in the instry are worried that every time the regulatory authorities take action, the price of bitcoin will fluctuate sharply, and there are risks in future hedging

2. The practical value of bitcoin is not high

the future development prospect of bitcoin largely depends on whether its payment function can be well reflected. Zhang Yuewen, a researcher at the Financial Research Institute of the Chinese Academy of Social Sciences, previously said that bitcoin does not play the core function of money payment, but only exists as an investment proct. If one day bitcoin can't be exchanged with the major currencies in circulation in the real world, it's worth less than a piece of waste paper

3, trading platform run away


however, bitcoin trading website is very fragile, the website may be attacked by hackers or shut down by competent authorities, and website operators may also run away with money, which may cause losses to the holders. At the end of October 2013, GBL, a trading website that was once popular in the bitcoin circle, suddenly shut down. Before most users had time to withdraw the funds from their accounts, GBL had already run away. According to incomplete statistics, there are about 500 victims, and the estimated loss may exceed 20 million yuan< 4. Control environmental risk

you also have to consider the environmental factors. Mining machinery is not a zero emission equipment, which will create a lot of noise and heat. In this way, you have to consider the physical and mental health of the operation workers, and you also have to consider the relationship between the surrounding residents. If you dare to build a mine of a certain scale in the community, the neighbors will certainly demolish it for you, unless you are a local tyrant< 5. Control technology risk. Bitcoin mining is mainly a technical problem in engineering, but the professional technology of bitcoin itself is not the key. You need project management talents, electricians, construction engineers and computer room construction talents. Although this knowledge is not complicated, experienced people can help you rece costs and control risks

is there any risk in investing in bitcoin? Bitcoin is very close to Ponzi scheme; Bitcoin has no price limit, and its market has always been like a roller coaster. The early recipients of bitcoin have a great advantage. If the follow-up funds stop entering this field, bitcoin cannot continue to appreciate. We should not be blindly confident, let alone gambling.
