❶ How does mining make money (Part 1)

If you want to understand the status of mining in the blockchain industry, you must have an understanding of the entire blockchain industry. Have a general understanding of the middle and lower reaches.

Upstream, such as the production of coins such as Bitcoin and mining-related companies. Among them are enterprises that design and produce mining machines, as well as the construction of mining farms and power generation equipment, and the operation of mining pools. These are all upstream enterprises of the blockchain.

Midstream, the midstream of blockchain refers to the transaction link and storage link. Many centralized and decentralized exchanges, as well as wallet development for various currencies, are midstream companies in the blockchain industry.

Downstream, various applications relying on blockchain technology, whether it is the underlying protocol, basic chain or application chain, all belong to downstream enterprises.

In the upstream, midstream and downstream industries, each link has its own logic for making money, and the level of risk is naturally very different. Below we introduce the categories.

The first type of way to make money is simple investment or speculation, specifically buying blockchain assets in the secondary market. The threshold is the lowest and the entry capital requirements are very low, as long as you can use the exchange to buy coins. The risk is high, and whether the profit or loss depends heavily on personal judgment of the market.

The second type of way to make money is early risk investment in projects, which is ICO. The threshold is not high, but the risks are extremely high. Some make dozens of times or even hundreds or thousands of times, while others lose all their money. First, because the project is in its early stages and is still a long way from being successfully implemented, the risk of project success or failure is high. Second, many unscrupulous projects are simply meant to defraud money and have no intention of bringing the project to fruition.

The third way to make money is cross-market hedging and arbitrage, referred to as arbitrage. The risk is small, but the threshold is now relatively high. The income from brick moving comes from the price imbalance in multiple markets. Now manual brick moving has been gradually eliminated. Programmed brick moving transactions and increasingly professional operations have higher technical thresholds.

The fourth type of way to make money is high-frequency quantitative trading, which is a single-market arbitrage method. Similar to moving bricks, the risk is low and the technical threshold is high. You need to be very familiar with both the development and trading systems to make a profit.

The fifth way to make money is to open an exchange. The threshold mainly comes from capital and technology, as well as operations. The main risk is regulatory and policy uncertainty.

The sixth way to make money is OTC trading. As the number of exchanges with OTC functions gradually increases, the profit margin for individuals is gradually decreasing.

The seventh category of money-making methods is the production of hardware such as mining machines and chips. Companies that are doing well in the industry include Bitmain, Avalon, BITFURY and other companies. Professional development skills are required to engage in this industry.

EighthA kind of way to make money, operating a mining pool. The threshold for a mining pool is mainly technology and miners’ computing power support.

The ninth category of ways to make money is program development, such as applications, quantitative trading programs, automatic trading tools, mining machine and mining pool program development, etc.

The tenth way to make money is mining. If Bitcoin is compared to currency, mining is the process of issuing currency. It is a low-risk, medium-yield investment category. The payback period of a Bitcoin mining machine is approximately 100 to 300 days, depending on the currency price. In the next article, we will explain the relevant knowledge of mining in detail.

❷ What does blockchain mining mean?

"Mining", as the name suggests, is the action that can appear in our minds, which is digging in the soil with a shovel, but now we It’s no longer a shovel, but a computer. Instead of digging in the soil, we dig in a pool of data, and instead of digging for physical objects like gold and coal, we compete for the right to keep accounts. 1. Mining is the process of confirming transactions in the Bitcoin system over a period of time and recording the formation of new blocks on the blockchain. These miners are called miners. 2. Mining is a bookkeeping process, miners are bookkeepers, and the blockchain is the general ledger. 3. The accounting rights of the Bitcoin system are decentralized, that is, every miner has accounting rights. Miners who successfully seize the accounting rights will receive new Bitcoin rewards from the system. Mining is the process of producing Bitcoins.

1. What does mining mean?

Ancient mining can be traced back to the selection of stone materials in the Stone Age. Later, with the rise of the metallurgical industry, mining and mineral processing technology gradually developed. This article introduces the aspects of open-pit mining, underground mining, tunnel support, rock crushing, tunnel ventilation, lighting, drainage, lifting, and mineral processing in ancient China.

Open-pit mining There are many surface outcrops, slopes or residual deposits of various metal veins or ore bodies. Therefore, open-pit mining became an important mining method in ancient times. Open-pit mining can be divided into excavation method and soil reclamation method.

2. Mining is the name for accumulated income from activities in Bitcoin.

Mining was brought about by the recent popularity of Bitcoin. Bitcoin is a virtual currency that can be exchanged for real currency. One of the ways to obtain Bitcoins on the Internet is to participate in related activities every day. These activities, like mining in online games, require slowly accumulating wealth in exchange for Bitcoins.

❸ How to monetize blockchain investment and make money from blockchain investment

In recent years, with the development of blockchain technology, more and more Investors are beginning to pay attention to blockchain investments, and they hope to gain more benefits by investing in blockchain. But the question is, how to realize blockchain investment and how to make money are the issues that investors are most concerned about. Next, let’s introduce how blockchain can be monetized and how to make money by investing in blockchain.

1. Methods of monetizing blockchain

1. Mining income: Mining is aThe most common method of monetization for blockchain investors is that investors can obtain income through mining. The size of the income depends on the investor's investment amount and the efficiency of mining.

2. Transaction income: Transaction is the most common way for blockchain investors to realize their profits. Investors can obtain income through buying and selling. The size of the income depends on the investor’s investment amount and the efficiency of the transaction.

3. Loan income: Loan is the most commonly used method of cashing out by blockchain investors. Investors can obtain income through borrowing. The size of the income depends on the investor’s investment amount and the efficiency of lending.

4. Investment income: Investment is the most common way for blockchain investors to realize their profits. Investors can obtain income through investment. The size of the income depends on the investor’s investment amount and the efficiency of the investment.

2. How to make money by investing in blockchain

1. Reasonable investment: Before investing in blockchain, investors need to fully understand the development trend of blockchain, and investment opportunities in the market in order to make more informed investment decisions.

2. Reasonable investment portfolio: When investing in blockchain, investors should construct a reasonable investment portfolio based on their own risk tolerance in order to obtain higher returns.

3. Reasonable investment strategy: When investing in blockchain, investors should formulate a reasonable investment strategy based on market changes in order to obtain higher returns.

2. Market risk: The blockchain market is a very unstable market with large price fluctuations. Investors should fully consider market risks when investing in blockchain.

3. Legal risks: Blockchain investment is restricted by different laws and regulations. Investors should fully consider legal risks when investing in blockchain.

4. Operational risk: Blockchain investment involves complex technical operations. Investors should fully consider operational risks when investing in blockchain.

4. Summary

As can be seen from the above introduction, the ways in which blockchain can be monetized include mining income, transaction income, lending income and investment income; blockchain The ways to make money by investing include reasonable investment, reasonable investment portfolio, reasonable investment strategy and reasonable investment timing; the risks of blockchain investment include technical risk, market risk, legal risk of loss and operational risk. Investors should fully consider these risks when investing in blockchain in order to obtain higher returns.

❹ Can anyone tell me whether blockchain transaction mining will lose money?

Losing money is possible under any circumstances. There is no 100% guarantee in this world. Be able to identify investments that will make money.

With the rise in the price of Bitcoin, the mining industry has become a veritable "gold mine". The large influx of newcomers and retail investors has made the Bitcoin market

Coin mining machines are hard to come by.

It is precisely in the face of such a market that the price of Bitcoin mining machines has also begun to rise. Not only that, because the number of Bitcoins is becoming increasingly scarce

, so mining The difficulty is getting bigger and bigger, and now the production capacity of Bitcoin mining will gradually decrease.

When the revenue of the mining machine is not enough to pay for the electricity consumed, the currency price at this time is called the "shutdown currency price". The influencing factors include currency price, electricity consumption

price, mining Mining difficulty, etc., if the currency price falls below the "shutdown currency price", miners need to shut down the mining machine, otherwise they will lose money.

So, any industry has certain risks, and only when you devote yourself to this industry, that is, after you have a deep understanding

, will you know There are risks involved, and you need to bear these risks before you can continue to develop in this industry.

Blockchain mining:

In 2009, Satoshi Nakamoto invented Bitcoin and set a limit of 21 million Bitcoins. In the Bitcoin network, by participating in the production of blocks and providing proof of work (PoW), you can obtain rewards from the Bitcoin network. This process is mining.

The concept of "mining" is taken from the existing concepts in our real economic life, such as gold mining, silver mining, etc., because minerals are valuable

That’s why people are driven to pay labor to dig.

Another important point in Bitcoin mining is that the miners participating in mining recognize the value of Bitcoin, and there are people in the market who are willing to mine the Bitcoin market

Spend money. So, Bitcoin mining makes sense.

❺ What is blockchain mining? How is blockchain mining?

What is blockchain mining? How is blockchain mining?
In blockchain Before the rise of miners, miners specifically referred to workers digging coal mines. The collective impression was that men with dark skin were covered in coal dust and except for their clothes. After the birth of the blockchain, miner is no longer just the abbreviation of coal miner, but has a new meaning: a person engaged in virtual currency mining.
For those who have not participated in mining, it may be difficult to understand blockchain mining, so today we will start with the most basic question: What is blockchain mining? How to mine blockchain?
What is blockchain mining?
There are two types of mining in the new era, the first is to mine Bitcoin. After each transaction occurs, it is not considered completed. The transaction data must be written into the database before it is established. The other partyOnly then can you actually receive the money. First, all transaction data will be sent to the miners, who are responsible for writing these transactions into the blockchain and completing mining to obtain profits.
The second type is to dig out copycats. Various "altcoins" such as Zcoin, Monero, Ethereum, Litecoin, and BitShares. After assembling a mining machine, connect to the designated mining pool and start computing at full load according to a specific algorithm. After completing one calculation cycle, you can obtain "one" virtual currency. Then put "this" currency on the online trading platform and cash out.

How to mine blockchain?
In the beginning, Bitcoin could be mined using a computer CPU. The founder of Bitcoin, Satoshi Nakamoto, used his computer CPU to mine it. The world’s first genesis block. However, the era of CPU mining has long passed, and now Bitcoin mining is the era of ASIC mining and large-scale cluster mining.
If you want to become a miner, it is actually relatively simple. You can just buy a special mining equipment and start mining. Mining does not require you to do it yourself. The computer actually performs specific calculations. For miners, it is enough to ensure the power supply and network connection of the mining machine.
Can blockchain mining still make money?
In the beginning, some people did get rich through blockchain mining, but as the number of miners increased, there was also great competition among miners. , profit margins are being compressed smaller and smaller. In addition, a machine that mines Bitcoin costs tens of thousands of dollars, and cannot dig out a single coin in a year. The input cost is high and the output is low. If the market conditions are unfavorable again, miners will Basically losing money.

Therefore, in addition to mining, more and more investors choose to invest in foreign exchange to make money. Unlike mining, the investment cost of foreign exchange is extremely low. For example, Juhui ggfx can be traded with a minimum of 8 US dollars. With long and short two-way operations, investors can make profits regardless of whether it is an uptrend or a downtrend. It is also very convenient for people who are busy and want to invest and make money. If you download Juhui ggfx’s MT4 trading software to your mobile phone, you can learn about the latest market conditions and participate in transactions through your mobile phone at any time, and complete orders as quickly as seconds. It is simple and fast. , the efficiency of making money is extremely high, so in addition to mining, this is also a good way to get rich.
Mining is not an easy task. Mining consumes a lot of resources because the calculation difficulty of generating virtual currency is very high and it is constantly changing. After every 2016 data blocks are generated globally, mining virtual currency The difficulty of the currency will increase once, so ordinary people must consider all aspects before joining the ranks of miners.

❻ What does blockchain mining mean?

In 2009, Satoshi Nakamoto invented Bitcoin and set a limit of only 21 million Bitcoins to be added to the Bitcoin network. , by participating in the production of blocks and providing proof of work (PoW), you can obtain rewards from the Bitcoin network. This process is mining.

The concept of "mining" is derived from the existing concepts in our real economic life. Gold miningMines, silver mining, etc., because minerals are valuable, people are driven to pay labor to mine them.

Another important point of Bitcoin mining is that the miners participating in mining recognize the value of Bitcoin, and there are people in the market who are willing to spend money on the Bitcoins they mine. So, Bitcoin mining makes sense.

Bitcoin Currency Features

1. Decentralization

Bitcoin is the first distributed virtual currency. The entire network is composed of users and there is no central bank. Decentralization is the guarantee of Bitcoin’s security and freedom.

2. Circulation around the world

Bitcoin can be managed on any computer connected to the Internet. Anyone can mine, buy, sell or receive Bitcoin regardless of location.

3. Exclusive ownership

Manipulating Bitcoin requires a private key, which can be isolated and stored in any storage medium. No one can obtain it except the user himself.

4. Low transaction fees

Bitcoins can be remitted for free, but a transaction fee of about 1 bit cent will ultimately be charged for each transaction to ensure faster transaction execution.

5. No hidden costs

As a means of payment from A to B, Bitcoin does not have cumbersome limits and procedures. You can make the payment by knowing the other party's Bitcoin address.

6. Cross-platform mining

Users can explore the computing capabilities of different hardware on many platforms.

❼ What is blockchain mining and what does it do? Detailed introduction to blockchain and virtual currency

When Bitcoin was first released, people discovered that it was decentralized and not It is controlled by any center; it is completely open, except for the encryption of transaction information, the entire system information is highly transparent, and the technology is open source; security, as long as you cannot control %51 of all nodes, you cannot modify the data arbitrarily, which makes it relatively safe ; Independence, the entire model and Bitcoin do not rely on any third party, all nodes verify and exchange data within the system without any intervention

Here we explain in detail what blockchain technology is, to put it bluntly It’s block + chain, so what is “block”? What is a "chain" again?

A block is a ledger. Transaction accounting is completed by multiple nodes distributed in different places, and each node records a complete account, so they can all participate in supervising the legality of the transaction, and at the same time Can jointly testify for it

Each block contains the cryptographic hash of the previous block, the corresponding timestamp, and the transaction data (usually a hash value calculated using the Merkle tree algorithm) represents), this design makes the block content difficult to tamper with. The distributed ledgers connected by blockchain technology can effectively record transactions between two parties, andThis transaction can be permanently checked.

The function of the hash function h(): convert a string of any length into a fixed-length (for example, 256 bits) output. The output is also called a hash value. This output is irreversible

It is difficult to find two different x and y such that h(x) = h(y), that is, two different inputs, There will be different output. Theoretically, two different inputs may have different outputs, but this is almost impossible. For example, if an infinite space is mapped to a finite space, there must be a many-to-one situation. The theory exists, but there are no rules. It is guaranteed that you cannot find this result through any mathematical inference. Why is it 256 bits here? Isn't it longer? Because 256 bits are secure enough.

Split the ledger into blocks. For example, a piece of paper in a book is a block. Each block records transactions within a period of time, such as 10 minutes.

We divide Each piece of paper is compared to a block. A part of content is added to each block. We call it a block header, which records the hash value of the parent block. Each block stores the hash value of the parent block. , connect all blocks smoothly to form a blockchain

Record the hash value of block 1 to the block header of block 2. In this way, the block header of each block is recorded The hash value of the parent block, each block is linked in order, this is called a blockchain. The first block has no block header and is also called the genesis block

The blockchain is a ledger. Only when transactions occur in the ledger will the money in your account increase. If you need to make a transaction, you first need an account number and password. Just like your bank card has an account number and password, others can make a transfer to you. The account password on the block ledger is the public key and private key

Lao Wang (who already has a private key and a public key) wants to transfer 10 BTC to Zhang, which requires some operations

It is proved that Lao Wang himself issued the transfer signature function Sign (Lao Wang’s private key + Transfer information: Lao Wang transferred 10 BTC to Zhang San) = signature of this special account
The verification is that Lao Wang himself issued the transfer verification function Verify (Lao Wang’s address + Transfer details: Lao Wang transferred 10 BTC to Zhang San) + Signature of this transfer) = true
Once the transfer is recorded in the block, no one can change it. Zhang San will increase it by 10 BTC, and Lao Wang will decrease it by 10 BTC accordingly. The entire operation is automatic, such as your wallet The app will help you do this. The app knows your private key, you tell the wallet the transaction content, the wallet signature is announced to the entire network, and it waits for others to verify the transaction

Centralized accounting The efficiency will be higher. Banks, governments or Alipay will help you keep accounts.They are all reliable, because they cannot touch your money unless they have your private key

There are some disadvantages in centralized accounting

Decentralized accounting allows everyone to keep accounts , everyone can keep a complete ledger. Anyone can download open source programs, participate in Bitcoin's p2p network, monitor transactions sent from all over the world, become an accounting node, and participate in accounting. Suppose Xiaoyi releases a transaction and broadcasts it to the entire network, and accounting node A listens. When this transaction arrives, A verifies that the transaction bit is true and puts it into the transaction pool to continue to spread to other nodes. Because it is spread through the network, the transaction pools of different accounting nodes are not necessarily the same at the same time. Every 10 minutes, from all accounting nodes Among the nodes, select one according to a certain method. After verifying that the transaction of this node is true, then compare the transaction records in the transaction pool of this selected node with the transaction records in the transaction pool of your own (A) node. The comparison is completed. After that, the transactions recorded by the selected accounting nodes will be deleted from the transaction pool, and the other accounting nodes will continue to record and wait for the next selection. There is a cycle every 10 minutes. During this 10 minutes, all accounting nodes will record accounts normally. , 10 minutes later, a node will be selected to use the transactions in its transaction pool as a new block. This block comes from the transaction pool of an accounting node I randomly selected among all the accounting nodes, and the cycle continues

A transaction is not completed once it is recorded. Only when the transaction becomes a certain block, the transaction is truly completed. This is a complete accounting process of decentralization. Your transaction will not be recorded immediately because the p2p network propagation takes time. If the node of the selected block has not received your transaction, the transaction will be not done. A block is generated every 10 minutes, but not all transactions within 10 minutes can be recorded. 10 minutes is just an average value

Due to the characteristics of decentralized accounting, accounting nodes with accounting rights will receive a 50BTC reward every ten minutes, which is about the same for every 210,000 blocks. In 4 years, the reward is halved. Bitcoin has been halved twice since its issuance. Then a new block is generated every ten minutes. The reward for this accounting node is 10.5 BTC. If it is halved every 4 years, the total number of BTC can be calculated. The amount is approximately 21 million, and it is expected to be mined in 2040. Recording the reward of a block is also the only way to issue Bitcoin. When BTC is mined, the only income that the accounting node can obtain is the transaction fee.

Accounting nodes compete for accounting rights through questions,

Find a certain random number that makes the equation invalid
SHA256 hash function (random number + parent block hash value + Transactions in the transaction pool) A certain specified value)
There is no other solution except traversing the random numbers starting from 0 and trying your luck. The process of solving the problem is also called mining, so solving this problemThe destination accounting node is also called a miner. The faster you traverse the random numbers, the more likely you are to get the accounting right. This traversal speed is called computing power by the mine bosses. In order to obtain this computing power , the mine bosses will buy more mining machines with higher computing power

Whoever solves the problem correctly first will get the accounting rights. Accounting node A is the first to find the solution, which is announced to the entire network. After other nodes verify that it is correct, node A obtains the block, gains 12.5 BTC, and restarts a new round of calculation after the new block. This method is called (POW) allocating accounting rights

It usually takes about 10 minutes to solve this random number. 10 is not absolute, because the process of solving this problem is a process of luck. In response to changes in computing power in the future, Bitcoin will increase or decrease the difficulty every 2016 blocks, about two weeks, so that the average block generation time is ten minutes

Each block contains The encrypted hash of the previous block, the corresponding timestamp, and the transaction data (usually represented by a hash value calculated by the Merkle tree algorithm) are included. This design makes the block content difficult to tamper with. Distributed ledgers connected by blockchain technology can effectively record transactions between two parties and permanently verify the transaction.

Different from traditional stored data, each node of the blockchain stores complete data according to the block chain structure. Each node of the blockchain is independent and has equal status, relying on The consensus mechanism ensures storage consistency, while traditional distributed storage generally synchronizes data to other backup nodes through a central node.

Mahjong is a traditional Chinese blockchain project. A group of four miners work together. The miner who first collides with the correct hash value of 13 numbers can obtain the accounting rights and be rewarded.

Many people say that blockchain is a scam and Bitcoin is a scam. This may be a scam, but this technology has been widely recognized and applied. The cryptography knowledge involved in blockchain can only be used by ordinary people. Even if you don’t understand it, the most important thing is to look at the problem from a relatively rational perspective. Don’t let the wind be the rain.

There is something incredible about this technology. It maintains absolute order without a center or supervision. This is the trust that only needs to be established by everyone’s consensus. Bitcoin created this consensus, and in the blockchain In the world everyone is fair and equal.

❽ How to make money by mining in the blockchain

The principle of making money by mining: PoW and mining.

In the beginning, Bitcoin could be mined using graphics cards, but in 2013, it was no longer possible to mine Bitcoin BTC using general-purpose computing programs for graphics cards. Bitcoins are now all mined using ASIC mining machines. ".

Similarly, the launch of Litecoin ASIC mining machines in 2014 also ended the use of graphics cards to mine Litecoin.Mine history. The current digital currencies that graphics cards can "mine" are Ethereum ETH, Ethereum Classic ETC, and Zcash Zerocoin ZEC.

Graphics card "mining" is not a profitable business. In fact, the earlier you start, the higher the income will be, and the income will decrease as more miners and graphics cards are added.

To put it bluntly, buying a high-priced graphics card to enter "mining" will definitely kill you. Purchasing a professional mining machine is a more cost-effective choice. Nowadays, the essential tool for personal mining is a mining pool. The function of a mining pool is to gather a large number of mining machine computing power to increase your chances of mining coins. At the same time, the coins you can mine in the future are evenly distributed to your account in advance.

Take Bitcoin as an example. If the entire Bitcoin network now generates a block every 10 minutes, this block contains 25 Bitcoins. Assuming that there are 10,000 people in the world participating in mining, then within these 10 minutes, only one lucky person will take away the 25 Bitcoins.

Others have nothing to gain. The principle of the mining pool is that everyone forms a team to mine and allocate according to the agreed distribution method, so that the miners' mining returns tend to be stable and the miners' risks are reduced.

In order to enhance the cost performance, you can also purchase some practical mining machines like Wanke Cloud, which can be used as ordinary hardware products and can also be used for mining, killing two birds with one stone.

There are several core operations of block chain transactions and digital currencies:

< p>The transaction network connected by decentralized databases is called the blockchain. All our clients (including mining machines) keep accounts together and confirm transfer transactions; a certain amount of digital currency is issued according to time.

Because the winner takes all, small and medium-sized retail miners have to unite to form a "mining pool" and record the cumulative workload in Shares. The higher the joint computing power, the greater the probability that the mining pool consortium will find the digital currency first. Large, increase the probability of finding newly issued digital currencies, and divide the mined digital currencies. This is called the PoW workload proof mechanism.
