Global computing power of bitcoin

1.

The following is the distribution chart of computing power:

the computing power of bitcoin is mainly controlled by some mine owners in the world, and the computing power of retail investors is very small, almost negligible. The computing power of China's mining pool even accounts for more than 80%, and China's voice is increasing

however, many digital currencies no longer need to be mined. Some digital currencies will be directly sent to investors through ICO, and Puyin is one of the representatives, but these digital currencies generally correspond to real assets

2.

Bitcoin bulls often mention that the scarcity value of this cryptocurrency is the main reason for its continued rise. Bitcoin is similar to gold to some extent. The growth of its supply is extremely slow, and it is still slowing down. Its total supply will only reach 21 million

with the increasing interest of institutional investors and retail investors in bitcoin, global exchanges such as the Chicago Board of options (CBOE) have launched bitcoin futures contracts. This is likely to encourage more institutional investors to invest in bitcoin, while at the same time further curbing the price volatility of bitcoin

this much anticipated bitcoin futures trading has been launched on the Chicago Board of options exchange, which represents a significant step in the legalization of cryptocurrency. Futures is a derivative / financial instrument, which can force dealers to buy and sell an asset at a specific time and price

There are only 21 million bitcoins

"graphics card mining" is a joke. In fact, it is running a specific algorithm to generate bitcoin through a large number of calculations

{rrrrrrr}

extended materials:

the concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, the open source software was designed and released, and the P2P network on it was constructed. Bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

unlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. 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

bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

on February 26, 2014, Joe Manchin, a Democratic senator from West Virginia, issued an open letter to a number of regulatory authorities of the US federal government, hoping that the relevant authorities would pay attention to the status quo of bitcoin's encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency

from 12:00 noon on January 24, 2017, China's three major bitcoin platforms officially began to collect transaction fees

4. Ming Ma went to buy cigarettes yesterday and bought 20 bags. Give the boss 50, find me 40, I pack in my pocket and go, not far away, the boss called me: you didn't take the cigarette! I left moved tears, took out ten yuan to the boss: you give me ten yuan more. The boss also left moved tears: young man, bring the cigarette, I will change a bag for you. Smoking the cigarette that the boss changed for me, the pure flavor can't help touching me again: boss, take the 50 one just now, and I'll change it for you. The boss took over the 50 and was moved again: young man, give me your change just now, and I'll change it for you. After receiving the money my boss gave me, I was moved again. I took out a mobile phone from my pocket: boss, I'd better give it back to you. The boss tears, shaking out a wallet: young man, wallet to you. At this time, the young man couldn't control it any more. He fell on his knees and cried, "brother, go to room 304 of the hotel next door and take your daughter back home from primary school!". The boss was surprised and sighed. He turned back to the shop and yelled, "red apricot, the watch is hiding. Come out and go back with your husband!"———— Are you thinking of me when I miss you

5. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system

1、 Mining principle

at the beginning, we could dig bitcoin with the computer CPU. The founder of bitcoin, Nakamoto Tsung, g out the world's first creation block with his computer CPU. However, the era of CPU mining has long passed, and now bitcoin mining is the era of ASIC mining and large-scale cluster mining

looking back on the mining history, bitcoin mining has gone through the following five times: CPU mining → GPU mining → FPGA mining → ASIC mining → large-scale cluster mining, The mining speed changes are as follows:

CPU (20mhash / s) → GPU (400mhash / s) → FPGA (25ghash / s) → ASIC (3.5tash / s) → large scale cluster mining (3.5tash / s * x)

mining speed, which is called computing power in professional terms, that is, the ability of computer to generate hash collisions per second. In other words, how many hash collisions can our miner do per second is the calculation force. Computing power is the ability to dig bitcoin. The higher the computing power, the more bitcoin you dig, the higher the return

in the world of bitcoin, a data block is recorded about every 10 minutes. All mining computers are trying to package the data block and submit it, and the person who successfully generates the data 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

to successfully generate data blocks, miners need to find the effective hash value. To get the correct hash value, there is no shortcut. You can only guess. The process of guessing is the process of computer random hash collision. If you guess correctly, you will get bitcoin

Mining method: from a miner to a large-scale mine, you need to prepare a miner, a computer that can connect to the Internet, an AUC, a raspberry pie, power supply and all kinds of connecting lines, etc. The connection order of various devices is network cable - & gt; Raspberry pie - & gt; Microusb cable - & gt; AUC-> 4Pin cable - & gt; Mining machine and power supply

< EM > Figure 3: Mine Map (scale of tens of thousands of mining machines) < / EM >

nowadays, the profit space of small and medium-sized absenteeism who take one mining machine home or deploy a small family workshop (dozens of mining machines) is very limited, and the mining instry is graally concentrating on enterprises and teams with low-cost power resources and professional deployment ability

there are many factors that affect the mining revenue, such as the performance and power consumption of mining machinery, the computing power and difficulty of the whole network, the deployment and operation and maintenance capacity of the mine, the availability of low-cost electricity resources, and the currency price and policy guidance, etc. At present, excellent mining enterprises have the ability of chip research and development, a lot of computing power, professional mine deployment and operation experience, etc. in the future, resources and computing power will be more and more concentrated in these mining enterprises

2. Mine pool

in addition to the above equipment, you also need a necessary tool - mine pool. The function of the mine pool is to gather a large amount of mineral computing power, increase your probability of getting bitcoin, and at the same time, distribute your future bitcoin income to your account in advance

the simple explanation is as follows: now the bitcoin network generates a block every 10 minutes, which contains 25 bitcoins. Suppose there are 1W people in the world participating in mining, then in these 10 minutes, only one lucky person has taken these 25 bitcoins, and the others have nothing. The principle of the mine pool is that everyone mines in teams and distributes according to the agreed distribution method, so that the income of the miners' bitcoin tends to be stable and the risks of the miners are reced. Let's take the most common PPS allocation method as an example. Suppose that your computing power is 10t, and the computing power of the whole mine pool is 100t. Your computing power accounts for 1 / 10 of the total computing power of the mine pool. Suppose that the mine pool can generate 10 bitcoins a day, then you can get 1 bitcoin a day

3. Cloud computing power

in reality, the supply of mining machines often exceeds the demand, and at the same time, the delivery of mining machines needs a long waiting period. Miner installation, commissioning, maintenance and other processes are very complex, which requires a lot of energy. Miners have to enre the noise and heat of miner. For miners, the biggest cost is not these, but the high electricity charges consumed by mining. The profit space of small and medium-sized miners is getting smaller and smaller, even negative

Mining income and risk mining income can be calculated by the following formula:

Mining income = generated bitcoin * currency price - mining machinery cost - electricity fee - custody fee

if you are just a small miner, generally you only need to dect mining machinery cost and electricity fee

Mining risks are as follows:

at present, the number of bitcoin is less than 4.5 million. If we do not issue additional bitcoin, the price of bitcoin will fluctuate, and the price callback will lead to the extension of the payback cycle

mining difficulty improvement at present, our machines can meet the market demand

Bitcoin can be cashed and converted into the currency of most countries. Users can use bitcoin to buy some virtual items, such as clothes, hats and equipment in online games. As long as someone accepts it, they can also use bitcoin to buy real-life items

bitcoin is a kind of P2P digital currency. Point to point transmission means a decentralized payment system

1. Bitcoin (bitcoin) is a kind of network virtual currency, which can buy real-life goods. It is characterized by decentralization, anonymity, and can only be used in the digital world. It does not belong to any country or financial institution, and is not subject to geographical restrictions. It can be exchanged anywhere in the world. Therefore, it is used as a money laundering tool by some criminals

2. On January 7, 2014, Taobao announced that it would ban the sale of Internet virtual currencies such as bitcoin and lightcoin from January 14. On February 26, 2014, Democratic Senator Joe Manchin of West Virginia issued an open letter to a number of regulatory authorities of the federal government of the United States, hoping that relevant institutions would pay attention to the status quo of bitcoin encouraging illegal activities and disrupting the financial order, and demanded that actions be taken as soon as possible to completely ban the electronic currency

3. On May 12, 2017, a global outbreak of bitcoin virus madly attacked public and commercial systems! Nearly 74 countries in the world have been seriously attacked

4. From August 1, 2017, global bitcoin trading platform will suspend recharge and withdrawal services. Bitcoin China digital asset trading platform will stop new user registration on September 14, and all trading businesses will be stopped on September 30
