1. We know that bitcoin investment is very popular. But bitcoin, as we all know, is hard to dig. However, if there is a good machine, it is not impossible to dig bitcoin successfully. Let's see how bitcoin is g

[1] make necessary preparations before mining

to start mining, we need to prepare graphics card, bitcoin wallet, mining software, etc. Because the GPU has considerable computing power, the graphics card is a good "mining" equipment

[2] start mining and choose a good ore pool

to start mining, there must be a mine pool with convenient operation and stable output. Its function is to subdivide the data packets for each terminal, and pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through precise algorithm. The btcguild ore pool abroad is recommended here, although there are many ore pools in China now, because there is no specific research and no evaluation. However, I would like to remind you that the output and income gap of each mine pool must be compared when selecting

take btcguild mine as an example to teach you the specific process of registration: register mine account - mine account setting - miner account setting - Download bitcoin miner - configuration of bitcoin miner - mining has started - log in btcguild to view bitcoin

the bitcoin g up at this time is stored in the website where the bitcoin is g up. It can't be traded or converted into paper money for the time being. What we need to do is to register an account on a trading platform. The bitcoin g up by the graphics card is imported from the website of foreigners to bitcoin China website. Only in this way can the bitcoin be handled freely, and it can be exchanged for RMB when it is sold or appreciated.
2. In order to understand the technical principle of bitcoin, we need to understand two important cryptographic techniques: hash code: it converts a long string into a fixed length string, and its conversion is irreversible, that is, it is impossible to guess the original string from hash code. Sha256 is mainly used in bitcoin protocol
public key system: corresponds to a public key and a private key, keeps the private key in the application and publishes the public key. When Party A transmits information to Party B, it can use Party A's private key to encrypt the information, and Party B can use Party A's public key to decrypt the information, so as to ensure that the third party cannot impersonate Party A to send the information; At the same time, when Party A transmits information to Party B, it is encrypted with Party B's public key and sent to Party B, and then Party B decrypts it with his own private key, so as to ensure that the third party cannot eavesdrop on the communication between the two people. RSA is the most common public key system, but the lliptic curve digital signature algorithm is used in bitcoin protocol. What's the difference between cash and bank account? Bitcoin is an electronic currency in BTC. In this article, it is also used to refer to the whole bitcoin system. Like opening an account in a bank, the corresponding concept in bitcoin is address. Everyone can have one or more bitcoin addresses, which are used to pay and collect money. Each address is a string that starts with 1. For example, I have two bitcoin accounts, and. A bitcoin account is uniquely determined by a pair of public key and private key. To save the account, you only need to save the private key file. Unlike bank accounts, banks keep all transaction records and maintain the book balance of each account, while bitcoin's transaction records are jointly maintained by the whole P2P network through a pre agreed protocol. How much money is in my account address? Although the current account balance can be seen by bitcoin software, unlike banks, there is no place to maintain the book balance of each address. It can only calculate the account balance in real time through all historical transactions. How do I pay? When I pay from address a to address B of the other party, the payment amount is e. at this time, both parties will announce the transaction information to each network node, telling address a to pay to address B, and the payment amount is e. In order to prevent the third party from forging the transaction information, the transaction information will be encrypted with the private key of address A. at this time, the network node receiving the transaction information can use the public key of address a to verify that the transaction information is indeed sent by address a. Of course, trading software will help us do these things, we just need to input the relevant parameters in the software. What will the network node do after receiving the transaction information? This is the most important part of the bitcoin system, which needs to be elaborated. For the sake of simplicity, only bitcoin protocol has been implemented. In the current version, each network node will save all transaction information synchronously. There are two kinds of transaction information in history, one is & quot; Verified & quot; The transaction information, that is, the verified transaction information, is stored in a series of "blocks". Each & quot; block" Is the previous & quot; bock" The ID of each block is the hash code of the hash code of the block and the new transaction information (see an actual block). The other category refers to those who also & quot; Unverified & quot; The transaction information just paid above belongs to this category. When a network node receives new unverified transaction information (possibly more than one), it can calculate the book balance of each address at that time because the node keeps all the transaction information in history, so it can calculate whether the transaction information is valid, that is, whether there is enough balance in the payment account. After eliminating the invalid transaction information, it first takes out the last & quot; block" Then, the unverified transaction information is combined with the ID, and a verification code is added to form a new "block". It needs a lot of calculation to build a new block, because it needs to calculate the verification code, so that the above combination becomes a block, that is, the first several bits of the hash code of the block are 1. At present, the first 13 bits need to be 1 (generally, the specific method is uncertain), which means that if the block is generated by enumeration method, the average number of enumerations is 16 ^ 13. Using CPU resources to generate a block is called "gold mining", because the proction of the block will get a certain reward, and the reward information has been included in the block. When a network node generates a new block, it will broadcast to other network nodes. However, this network block may not be accepted by the network, because it is possible that other network nodes have proced the block earlier. Only the earliest block or the block with the largest number of subsequent blocks is valid, and the remaining blocks are no longer used as the initial blocks of the next block. How does the other party confirm that the payment is successful? When the payment information is distributed to the network node, the network node begins to calculate whether the transaction is valid (that is, whether the account balance is enough to pay), and attempts to generate blocks containing the transaction information. When six blocks (one direct block and five subsequent blocks) contain the transaction information, the transaction information is considered "verified", so that the transaction is formally confirmed, and the other party can confirm the successful payment. A possible problem is that I will pay the balance of address a to address B, and at the same time pay to address C. If I only verify that the single comparison transaction is valid. At this point, my way of cheating is to generate six blocks including B to B and six blocks including C to C before the truth is revealed. Because I need a very long CPU time to generate a block, compared with the whole network, the probability of my cheating success is very small. What is the motivation of network nodes to proce blocks? As can be seen from the above description, in order to make the transaction information effective, the network node needs to generate 1 and 5 subsequent blocks to contain the transaction information, and such block generation is very CPU intensive. How to let other network nodes help to proce blocks as soon as possible? The answer is very simple. The agreement stipulates that BTC will be rewarded for the address where the block is proced, as well as the Commission promised by both parties. At present, the reward for procing a block is 50btc, which will be halved every four years in the future. For example, the reward will be 25btc from 2013 to 2016. Is the transaction anonymous? Yes, and No. All bitcoin transactions are visible. We can check all transaction records of each account, such as mine. But what's different from the banking monetary system is that everyone's account itself is anonymous, and everyone can open many accounts. In general, anonymity is not as good as it claims. But bitcoin has another advantage in doing black market trading: it can't be frozen. Even if the police trace a bitcoin address, there is nothing they can do unless they trace the computer used by the exchange based on the Internet address. How to ensure that bitcoin does not depreciate? Generally speaking, in the case of equivalent trading activities, the value of money is inversely proportional to the amount of money issued. Unlike the traditional money market, the central bank can determine the amount of money issued. Bitcoin does not have a central issuing institution. Only by procing blocks can we get a certain amount of BTC currency. Therefore, bitcoin's new amount of money depends on: 1. The speed of procing blocks: bitcoin's agreement stipulates that the difficulty of procing blocks is fixed at an average of 2016 every two weeks, about 10 minutes. Moore's law of doubling CPU speed every 18 months will not speed up the proction of block. 2. The number of rewards for block proction: at present, 50 BTC is awarded for each block proced, which is halved every four years. In 2013, 25 BTC is awarded, and in 2017, 12.5 BTC is awarded. Considering the above two factors, bitcoin's currency issuing speed is not controlled by any single node in the network. Its protocol makes the currency stock known in advance, and the maximum stock is only 21 million BTC
3. Users can buy bitcoin, and at the same time, they can use computers to do a lot of calculations according to the algorithm to "mine" bitcoin. 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. Due to the decentralized programming of the bitcoin system, only 25 bitcoins can be obtained every 10 minutes. 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. According to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by monetary authorities, does not have monetary attributes such as legal compensation and compulsion, is not a real currency, does not have the same legal status as currency, and cannot and should not be used as currency in the market, Citizens' investment and transaction of virtual currency are not protected by law
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
3. The above explanation is for reference only. Investors should not use such information to replace their independent judgment or make decisions only based on such information, which does not constitute any investment operation

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. But in China, bitcoin is forbidden to circulate

unlike all 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 biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity

extended information:

Article 1 of the announcement on preventing the financing risks of token issuance accurately understands the essential attributes of financing activities of token issuance. Token issuance financing refers to the so-called "virtual currency" raised from investors by the financing subject through the illegal sale and circulation of token. In essence, it is an unauthorized illegal public financing behavior, suspected of illegal sale of token bills, illegal issuance of securities, illegal fund-raising, financial fraud, pyramid schemes and other illegal criminal activities

Relevant departments will closely monitor relevant developments, strengthen cooperation with judicial departments and local governments, strictly enforce the law in accordance with the current working mechanism, and resolutely deal with market chaos. If suspected crimes are found, they will be transferred to judicial organs. The token or "virtual currency" used in token issuance financing is not issued by the monetary authority, does not have such monetary attributes as legal compensation and compulsion, does not have the same legal status as currency, and cannot and should not be used as currency in the market

Article 2 no organization or indivial may illegally engage in token issuance and financing activities. As of the date of this announcement, all kinds of token issuance and financing activities shall be stopped immediately. Organizations and indivials that have completed the token issuance and financing should make arrangements such as refund, reasonably protect the rights and interests of investors, and properly handle risks. Relevant departments will seriously investigate and deal with the activities of token issuance and financing that refuse to stop and the illegal behaviors in completed token issuance and financing projects

Bitcoin is actually a useless string of numbers, but it is recognized as useful, just like diamonds, antiques, calligraphy and paintings, game skin and so on. They can't be eaten or used, but we will recognize their value


"mining" just allows more people to participate in the construction of blockchain network. Is it really good that so many electricity charges are used to "calculate" a series of virtual values? Bitcoin is not a hedge. The price of bitcoin fluctuates greatly. Speculation on bitcoin may become rich overnight or become poor overnight. Bitcoin is not as safe as it claims. In 2014, the world's largest bitcoin trading website, mtgox, was hacked and went bankrupt, and the $467 million worth of bitcoin evaporated instantly. Criminals use it to launder money, evade taxes and so on. It is also quite difficult for the government to investigate. The above personal opinions are welcome to be criticized and corrected. Agree with me, please click like before you go, thank you! Like me, please pay attention to me, thank you again


7. You're half right. People with mining machines can dig bitcoin with the power of their mining machines. Now it's almost impossible for ordinary people to dig bitcoin with their home computers. But if you want to get bitcoin, you can buy it on the bitcoin trading platform. Two months ago, before the domestic bitcoin trading market was shut down, one bitcoin was worth 12000 yuan, Moreover, the recent rise of bitcoin is still very fierce. I don't know when to open bitcoin trading again in China.
8. Bitcoin Mining: miners use a lot of computing power to process transaction information and ensure the safe and stable operation of the system, which is called mining
in the process of mining, the computers of all nodes will perform specific operations together, just like doing a very complex random arithmetic problem, which needs to do billions of calculations per second. At the same time, the more people are mining, the more difficult the operation is, and the more operations they need to do. Whoever does the right thing first can get the bookkeeping right and get the reward at the same time
Miner: miner refers to the person who participates in bitcoin mining, and can also be called a node in the bitcoin system. Because the mining process requires a lot of computing and resource consumption, if only one computer is provided, in the case of more and more miners, it will be more and more difficult to get a reward. At this time, some miners will increase the number of mining equipment.
