Bitcoin dig
Find the code on the bitcoin system, and you can dig bitcoin if you find the code
every other time point, the bitcoin system will generate a random code on the system node, and all computers in the Internet can search for the code. Whoever finds the code will proce a block, and then get a bitcoin. This process is often called mining. Computing this random code requires a lot of GPU operations, so the miners purchase a large number of graphics cards to get bitcoin profits more quickly, which is also an important reason for the recent shortage of graphics cards

characteristics of bitcoin
The total amount is limited, only 21 million BTC2. Anyone can issue bitcoin, but it is more and more difficult
3. Compared with the central bank currency, it is safer and almost impossible to be stolen
The transaction process is completely anonymous and cannot be tracedStep 1: prepare mining machines and pools
if you want to dig bitcoin, you must prepare professional equipment. At present, there are many professional mining machines on the market, and the pool is also essential. When you choose a pool, you should also compare the output and income gap of each pool, and then choose the most suitable one
Step 2: register and set the mine account
after the mine is ready, register the mine account and set a common email. When setting the mine account, each CPU or GPU needs to set a mine account
Step 3: download the bitcoin miner
after you register and set up your account, you need to download the bitcoin miner. When downloading the miner, be sure to choose the miner that can make your CPU and graphics card play the most function. After downloading, set the server, user name, password, device and so on
Step 4: Mining
after setting up the miner, click the "start mining" button, the miner will enter the state of full speed operation, and the miner will start mining automatically.
Bitcoin is a kind of network virtual currency. 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. Assuming that the mining computing power is 100 mhash / s and the total computing power is 4000 ghash / s per day, 3600 bitcoins can be g out every 24 hours
China's computing power has accounted for more than 75% of the world, that is to say, 75% of bitcoin in the world is made in China. How long does it take to dig a bitcoin
bitcoin used to be very good at "digging", which can be done by ordinary computer CPU, and it can automatically "solve problems" by downloading software. But with the rise of currency price, more and more people want to "solve the problem", and the difficulty of mining is also increasing. Now, the amount of computation needed to dig a bitcoin is beyond the reach of ordinary people. Ordinary computers can't afford it
instry insiders said that in 2014, 100 bitcoins were generated from 500000 yuan of electricity charge per day, and the cost of electricity charge alone was 5000 yuan per coin. But now, the same cost has more than doubled, and the electricity cost of each bitcoin is as high as 10000 yuan
in the generation mechanism of bitcoin, mining reward is decreasing. At the beginning of the birth of bitcoin, the miners could get 50 bitcoins for each page of the ledger, and then 25 bitcoins for each page of the ledger, decreasing in turn. It's like digging gold. At first, it's more and less. The time point at which each new reward is reced by half is called half bitcoin proction
assuming that the mining computing power is 100 mhash / s, the total computing power is 4000 ghash / s per day in 2014, and 3600 bitcoins are g out every 24 hours
now, we can understand the difficulty of bitcoin digging in this way, which is equivalent to 100 million dice throwing numbers less than 100 million and 50 million. Whoever throws them first will get the bookkeeping right. At this point, 1050 million is a hash value. The process of throwing dice is called hash collision. The unit of mining power is the number of hash collisions per second
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

When bitcoin nodes connect with each other, they will get transactions they don't have from each other. But because bitcoin has accumulated a large number of transactions for a long time, it is very difficult for two nodes to compare which transactions you are missing / which transactions I am missing one by one
to solve this problem, Nakamoto Tsung invented the important technology of block chain. Nodes use blocks to synchronize transactions, which ensures the data consistency of all nodes, and ensures the uniqueness of the blockchain by competing for block packing rights (that is, mining)
① a block and blockchain
a packet formed by a transaction over a period of time is called a block. On average, bitcoin generates a block every 10 minutes, and each block is linked to the previous block to form a blockchain
② the transaction data is synchronized with the block as a unit
the block is numbered from 1, so after node a connects with node B, it is convenient to synchronize the transaction data as long as the block number height of both parties is checked. For example, if node A's own block height is 100 and node B's block height is 110, all it needs to do is request B to synchronize the 10 blocks 101-110<
③ reward for packed blocks
in order to ensure that there are nodes to pack bitcoin transactions, bitcoin rules stipulate that nodes of packed transactions will receive bitcoin as reward
A. part of the package reward comes from the transaction fee paid by the transaction creator (100-1000 transaction fee per KB)
B. the other part comes from the initial distribution of 21 million bitcoins. At the beginning, the reward is 50 bitcoins for each block. After that, the reward will be halved for every 210000 blocks (about four years). Until about 2140, the reward for each block is less than 1, and the total reward for each block is 21 million bitcoins, This is the source of the total amount of 21 million bitcoins (2099999.97690000 to be exact)
after 2140, the package reward will only come from the transaction fee paid by the transaction creator<
④ competition for block packing right
node packing transaction only needs to consume very low-cost network and computing resources. The existence of packing reward (at present, the packing reward for each block is 25 bitcoin, about 40000 yuan), makes a large number of nodes want to pack transactions. In order to ensure the uniqueness of the blockchain, bitcoin rules stipulate that nodes use a method similar to "coin tossing" to compete for the right of transaction packaging. Nodes constantly toss coins. Whoever first throws the results that meet the rules will get the right to pack the transaction in this block, as well as the package reward of this block
1. First of all, connect the network cable, plug the network cable into the network cable interface of the mining machine, and remember to plug it tightly. Only when the miner is connected to the Internet, there is no limit to the broadband
extended data
users can buy bitcoin, at the same time, they can also use computers to "mine" bitcoin according to a large number of calculations. When users "mine" bitcoin, they need to use the computer to search for 64 bit numbers, 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 set of numbers, then they will get 25 bitcoins
e to the decentralized programming adopted by the bitcoin system, only 25 bitcoins can be obtained every 10 minutes, and by 2140, the maximum number of bitcoins in circulation will reach 21 million. In other words, bitcoin system is able to achieve self-sufficiency, resist inflation through coding, and prevent others from destroying these codes
warm tips:
1. The above explanations are for reference only, without any suggestions
2. Before investing, it is recommended that you first understand the risks existing in the project, and clearly understand the investors, investment institutions, chain activity and other information of the project, rather than blindly investing or mistakenly entering the capital market. Investment is risky, so we should be cautious when entering the market

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

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 worthlessHave you ever heard of "virtual currency"“ "Virtual currency" is actually a very popular currency value on the Internet. This kind of currency is not real money because it can't flow into the market. This article is about a kind of "virtual currency", called bitcoin. Bitcoin is a kind of virtual currency, but after a long period of development, many people put bitcoin into the market
money is something that human beings need very much. Without money, market exchange cannot continue. In ancient times, shells could be used as money, while in modern times, what we call "virtual money" can also be used as money. Bitcoin was a very common virtual currency more than a decade ago, and it didn't have much value. But in a decade, bitcoin has risen by a very many fold. Once upon a time, a man bought 100000 bitcoins, which rose 13 million times. Now how much is it worth
however, there are not many people like Li Xiaolai who wake up quickly, because many people will inlge in this kind of toxic things, but Li Xiaxia can get away quickly, which must be e to his excellent knowledge and his knowledge wealth
