⑴ 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 no longer use shovels, but computers. 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.

⑵ What does mining mean?

To put it simply, mining is to use a chip to perform a calculation related to random numbers, and after getting the answer In exchange for a virtual currency. Virtual currencies can be exchanged for currencies of various countries through certain channels. The chip with stronger computing power can find this random answer faster, and theoretically, the more virtual coins can be produced in a single slot in a single time. Since it involves random numbers, you can only get rewards if you happen to find the answer. It is possible that one chip will find the answer in the next second, or it is possible that ten chips will not find the answer for a week. The more chips can be calculated simultaneously, the easier it is to find the answer, and mining machines with built-in multi-chips have appeared. And multiple mining machines forming a "mine" to mine at the same time can improve efficiency. Mining Pitong Pool consists of multiple "self-employed individuals" joining an organization to mine together. No matter who finds the answer and digs out virtual coins, everyone will simultaneously receive corresponding rewards based on the computing power they contributed. This method enables "self-employed individuals" to mine together. “The income is more stable.

Give a popular example:

I randomly write a string of numbers on a piece of paper and give some hints. Whoever guesses correctly will give him a bonus (mining)

Smart people can make more guesses based on prompts (Computing power)

Someone pays many people to come back and guess together (mine)

Someone calls everyone together to guess. No matter who guesses, the bonus will be distributed according to the proportion of each person’s guesses ( Mining pool)

As you can see from the above example, the smarter the person, the more guesses they can make, the greater the chance of guessing, and the more profits they can obtain accordingly.

We often watch There are miners who constantly upgrade their computer configurations or buy multiple computers in order to mine. The actual purpose is to increase their computing power. The process of mining is that each miner competes with all miners to calculate a share of Bitcoin in a period of time. The essence is one person's computing power VS the world's computing power. It can be seen that mining is not so easy.

What is computing power?

In the process of "mining", we need to find the corresponding solution. To find the solution, there is no fixed algorithm and we can only rely on computers. Random hash collisions. The number of hash collisions a mining machine can do per second is the representative of its "computing power", and the unit is written as hash/s. < /p>

What are the mining of mining < /p>

First of all, the mining in the network refers to the calculation of the miners for a certain workload to calculate the calculation It can also be seen as a process of adding new transactions to the ledger that records past transactions of digital currency.

The limitation of the above definition is that it does not clearly indicate what is mined. Mining digs out blocks. Since these blocks are composed of digital symbols, it can also be said that what is dug out is just a string of numbers. However, these numbers represent the rewards that miners can obtain, or income, so what is mined can be said to be income. However, block rewards fluctuate with currency prices. The biggest factor affecting currency prices is the size of the audience. When Bitcoin was first born, any computer could mine hundreds or thousands of Bitcoins every month. Since no one cared about it, miners needed tens of thousands of Bitcoins to buy a pizza. However, as the number of people accepting Bitcoin increased, the price of Bitcoin increased tens of thousands of times! Therefore, in the end we can say: What mining mines is the consensus expectation of society for a certain digital currency in the future.

Miners refer to a group of people who focus on "mining". They can refer to one person or a group. With the continuous advancement of technology, miningWorkers are no longer limited to using hardware equipment to mine. By investing time, energy, and even brainpower, they can mine varying amounts of digital currencies in some projects. Since what is being mined is the consensus expectation of the future society for a certain digital currency, the income is full of uncertainty. In order to better distinguish, the author distinguishes between "hardware" mining and "software" mining.

1. “Hardware” mining

Since this mining requires a large amount of hardware equipment, it is basically the people who come into contact in the early stage who gain the most, and the requirements are very high. , gradually transitioning to specialization. At present, it is difficult for a single miner to survive in the miner arms race of computing power, hardware, and iteration speed. Therefore, most miners will choose to cooperate and achieve profitability through jointly built mining pools.

Because it is the consensus expectation of mining, this makes the price fluctuate particularly violently, and hardware miners’ equipment investment, maintenance, iteration, site rental, labor, water and electricity bills, etc. all require real money. Therefore, these miners are under great pressure and may lose everything if they are not careful. There are many factors that affect consensus. In order to achieve stable, sustainable, and maximized benefits, hardware miners usually choose: in the bull market, sell the coins in their hands, exchange them for legal currency or other stable coins, and wait quietly for the bear market; , try to accumulate coins as much as possible, and use the previously accumulated legal currency or stable currency to "keep yourself warm during the winter."

As a hardware miner, I look forward to the bull market, but also do not refuse the arrival of the bear market. In a bull market, a large increase in miners will also increase the difficulty of mining, and the rewards will drop sharply; in a bear market, the currency price will halve, but the mining rewards will increase due to the decrease in miners. Through the alternation of bulls and bears, they can maximize their returns. The alternation of bulls and bears, even if it occurs every four years, requires perseverance that is unbearable for ordinary people.

2. “Software” miners

This type of miner refers to the act of mining by investing money, time, energy, brainpower and other non-hardware.

With the advancement of technology, the POW mechanism can no longer meet people’s needs. Currently, there are more than 30 consensus algorithms that have been widely used on the market. You can see POS, DPOS, POI, POB, POA, etc. It is a supplement to the POW mechanism. In this type of mining behavior, miners usually need to buy and hold a certain amount of digital currency, and obtain income through the appreciation of the digital currency. In order to maximize profits, this holding time is usually measured in years, with the bull-bear cycle of the currency market as a major cycle, so impatient miners are destined to be eliminated.

  There is another type of miner here, and Zangbaoge would like to focus on it: it is the miner who does not invest money but does candy and wool in the early stages of each project (for the convenience of explanation later, it will be replaced by Token). Of course, on the UGC platform Creation also belongs to this type of miners.

Digital currencies are currently divided into mainstream currencies and altcoins, as well as world currencies and competitive currencies. At present, the tokens we get from rolling candies and wool are basically competitive coins: digital currencies issued by the project party for project development financing and promotion (not to make up for the shortcomings of digital currency technology). This type of digital currency will first be managed by a centralized team; secondly, it will go through a growth process from young to powerful; and finally, it is the growth results of the project that will affect the final value of the currency in the hands of users. In this type of mining, miners pay time, energy, brainpower, etc., and the tokens obtained can be regarded as equity or proof of rights with dividends. Then, what determines the income of miners is whether this project can survive and be accepted by more and more groups. If it can grow into a unicorn in the blockchain industry, the income it brings to miners will be enough. Wealth is free.

However, if there is competition, there will be survival of the fittest. Among the project developers of alternative coins, a large number of projects are destined to die. In this way, the Tokens in the hands of miners are just numbers and cannot produce any value. Therefore, the choices miners usually face are: sell their tokens as soon as possible and exchange them for mainstream currencies such as BTC or hold them patiently and wait for these tokens to achieve a shocking reversal like Ripple. Five yuan investment, hundreds of millions of profits, such an opportunity is no longer enough to be described as daydreaming, but the currency circle is a place where myths are created, so the treasure house’s approach is to collect! After all, there is no point in selling the token in your hand for ten or eight yuan. Zangbaoge is more willing to grow with the project. At the same time, it casts a wide net and finds ways to obtain more project tokens. It mentions the wallet and quietly waits for the project to grow. Come dividends.

3. Conclusion

It can be concluded from the article: No matter whether it is "hardware" or "software", what mining digs out is the expectation of future income: If more people recognize it in the future, the benefits brought by the coin will be better; if no one cares about it in the future, the coin may return to zero, and the miners' benefits will be negative. But expectations, which usually take a long time to verify, including the opportunities that come with them, are often hidden in the initial mediocrity. Blockchain will inevitably bring about disruptive social changes. This is the most basic belief of miners who join the currency circle, so you might as well give up the trivial matters in front of you, hold digital currencies patiently, and use the cycle of bull and bear replacement as the operating frequency. In this way, you can Get the most bang for your buck.

⑷ What does blockchain mining mean?

In 2009, Satoshi Nakamoto invented Bitcoin and set the number of Bitcoins to only be 21 million. By joining the Bitcoin network, you can obtain Bitcoins by participating in the production of blocks and providing proof of work (PoW). Network rewards. 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, people are driven to pay labor force. dig.

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’s monetary characteristics

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.

⑸ What consensus mechanisms are currently used in the blockchain and what are their respective advantages, disadvantages and scope of application

There are currently four main types of consensus mechanisms: Pow, Pos, DPos, and Pool
1. Pow workload proof is the familiar mining. Through AND or operation, a random number that meets the rules is calculated, that is, the accounting right is obtained, and the data that needs to be recorded in this round is sent to the entire network. Other nodes verify and store them together;
Advantages: Complete decentralization, nodes can enter and exit freely;
Disadvantages: At present, Bitcoin has attracted most of the world's computing power, and other blockchain applications use the Pow consensus mechanism. It is difficult to obtain the same computing power to ensure one's own security; mining causes a lot of waste of resources; the period for reaching consensus is long and is not suitable for commercial applications

2. PoS equity proof, a type of POW Upgrade the consensus mechanism; according to the proportion of tokens held by each node and time;Low mining difficulty, thus speeding up the search for random numbers.
Advantages: It shortens the time to reach consensus to a certain extent
Disadvantages: It still requires mining, which essentially does not solve the pain points of commercial applications

3. DPos share authorization certification mechanism , similar to board voting, currency holders vote for a certain number of nodes to perform verification and accounting on their behalf.
Advantages: Significantly reduce the number of nodes participating in verification and accounting, and can achieve second-level consensus verification
Disadvantages: The entire consensus mechanism still relies on tokens, and many commercial applications do not require the existence of tokens
br />
4. Pool verification pool, based on traditional distributed consistency technology, plus data verification mechanism; it is a consensus mechanism currently used in a wide range of industry chains
Advantages: No tokens are required It can work and achieve second-level consensus verification based on mature distributed consensus algorithms (Pasox, Raft);
Disadvantages: The degree of decentralization is not as good as bictoin; more suitable for multi-center business models with multi-party participation
>
There are huge advantages in using the consensus mechanism to ensure data consistency (the consensus mechanism was first proposed by Ripple, a network transaction synchronization mechanism that prioritizes data correctness. In the consensus network, no matter how the software code changes, it cannot There is no way to enter the network without consensus, let alone a fork).
————————————————
PS: A little self-deprecating, although the consensus mechanism can definitely ensure that no hard fork will occur at any time. However, the disadvantage of this mechanism is also obvious, that is, it takes much longer to achieve consensus with other nodes than the current Bitcoin network. In extreme cases, the consequences of being disconnected in the Ripple consensus mechanism network are also terrifying.

It is possible that your home has a power outage for one day, and the entire system will no longer be able to achieve consensus with other Rippled nodes the next day (the consensus mechanism actually requires more than 80% of the nodes to recognize your data, your Submission will be accepted by other nodes, otherwise the connection will be exclusively refused), and you can even only clear all more than 500 GB of your data and resynchronize before you can connect to other Ripple nodes.

So currently, the existing Rippled end is not suitable for civilian use (for commercial use, the impact is relatively small. For example, RL's own Rippled node is hosted in the Amazon cloud data center. If it does not respond for a long time, it can be very high. The amount of compensation is claimed, and that kind of place is almost uninterrupted except for major disasters). This is also one of the aspects that RL has always wanted to improve.

⑹ 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 with a graphics card, but in 2013, it was no longer possible to mine Bitcoin BTC with a graphics card’s general computing program. All Bitcoins are now mined with ASIC mining machines perform "mining".

Similarly, the launch of Litecoin ASIC mining machines in 2014 also ended the history of Litecoin mining using graphics cards. 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.

(6) The difference between blockchain mining and woolen wool. Extended reading

There are several core operating cores of blockchain transactions and digital currencies:< /p>

The transaction network formed by decentralized databases is called the blockchain. All our clients (including mining machines) keep accounts together, confirm transfer transactions, and issue a certain amount of digital currency 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.
