Ⅰ Do Bitcoin Mining Machines Really Exist?

Wow, do Bitcoin Mining Machines Really Exist? I think Bitcoin is a virtual currency, please ask again

II What does blockchain mining mean?

In 2009, Satoshi Nakamoto invented Bitcoin and set There are only 21 million Bitcoins. If you join the Bitcoin network, you can get rewards from the Bitcoin network by participating in the production of blocks and providing proof of work (PoW). 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 work hard. 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.

Bit Currency characteristics of coins

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.

Ⅲ What is the principle of Bitcoin and blockchain and what is mining (3)

Continuing from the previous issue "Bitcoin and What is the principle of blockchain? What's going on with mining? (2)》

Before I start, let me share with you an interesting thing I saw yesterday.

(On the gate of a community in Shenyang, 66 locks are hung one after another, and it is known as the "cheapest access control system".

It turns out that there were always foreign vehicles coming in and out of this community, so the owners spontaneously built this "access control system". Each lock has a number, and the car owners in the community only need to use the key to open it.Open the corresponding lock to open the door. Residents said that this method saves money and effort and is particularly easy to use. )

This is equivalent to the technical materialization of blockchain:

Specific features: decentralization (no need for unified management); traceability (whoever has the lock, look for it); non-tamperability (one person, one lock, one key), this is my understanding of the block The most thorough understanding of the chain.

"Let's stop talking and get back to the story." We said before that there is a difficulty setting of N bits. How to determine this N bit? Obviously, the previous 0, The more there are, the more difficult the problem becomes.

Why is it difficult to count more? Let's imagine that in this problem you can't back-calculate, you can only try randomly one by one. The probability of 0 appearing and the probability of 1 appearing on each digit are both 50%, so what is the probability of the first 0? The probability is 1/2. If the second digit is 0, what is the probability? The probability is also 1/2, the third digit is 0, the probability is also 1/2, until the last digit is 0, the probability is also 1/2, so when multiplied, the result is the nth power of (1/2).

Obviously, the larger n is, the higher the difficulty is, and the smaller n is, the smaller the difficulty is.

When Satoshi Nakamoto was designing it, he ensured that he would produce a block and package it every ten minutes. With thousands of pieces of information, how can we guarantee it? That is to say, adjust the difficulty of this n?

Let’s take an example. For example, there are 10,000 mining machines in the world. The computer power of each of these 10,000 mining machines is 14 T per second. , that is, 14T hash operations can be calculated per minute. So what is 14T?

First of all, 1T is 10 to the 12th power, so this number is (1.4*10) to the 13th power per second, which is for each mining machine Calculated in one second, multiply by 10 to the 4th power, which means there are 10,000 mining machines, and then you have to multiply it by 10 minutes, which is about 600 seconds. This number is about (8*10) to the 19th power. In other words, we can perform so many operations in ten minutes.

Then let’s think about it again. If the probability is (1/2) raised to the nth power, what do you think? If you come up with this block, the number of calculations you need to make is 2 to the nth power. If your probability is 1/64, you will have to calculate this block 64 times on average.

In the same way, if you have calculated it so many times, then it is roughly equivalent to how many powers of 2, we canThrough calculation, it is found that if n is equal to 66, your probability of occurrence at this time can be calculated as (1/2) raised to the 66th power, and then the average number of calculations you need is 266, which is approximately (8*10) to the 19th power, so in this case the mining machine will set the difficulty to n equal to 66, so the first person who can calculate that the first 66 bits are all 0 will successfully package the block and successfully mine To the mine.

You have no way to make your luck better. All you can do is buy more mining machines and mine as hard as you can, so that you may get this Bitcoin.

This is probably the principle.

IV The Essence of Blockchain Mining

Investment products are usually divided into debt products and equity products based on the certainty and uncertainty of returns and risks. Creditor's rights pursue absolute returns, while equity investors are willing to take risks and obtain floating returns. Usually these two are completely different products. However, the emergence of blockchain technology has made it possible to integrate these two types of products.

Take Bitcoin, the first concrete application of blockchain, as an example. BTC is released in mining mode. Every ten minutes, the mining machine that grabs the accounting rights is rewarded with 6.25 Bitcoins. Based on the current computing power difficulty, the output of a mining machine can be expected. Therefore, the income from short-term investment in mining machines is relatively certain, but due to the huge volatility and growth space of Bitcoin itself. The life cycle of a mining machine is more than one year. Investment in mining machines essentially requires a judgment on the future BTC capital value and risks. Bitcoin mining provides a new model of short-term deterministic returns and long-term floating returns.

The reason why this model was established is that first of all, everyone formed an initial consensus on the value of BTC and there was a secondary market for free transactions. The mined BTC can be traded and sold at any time to obtain deterministic returns, or it can be held as an asset for a long time to obtain long-term investment returns.

Equity investment fully embodies the capital spirit of sharing risks and sharing profits.

A sign of the maturity of the capital market is the richness of equity products and tools.

Chinese society is generally dominated by the creditor's rights mentality, and investment capital preservation is the basic expectation of most investors. On the one hand, this mode of thinking is due to historical factors. Traditionally, business risks and returns have been viewed in isolation. It is believed that business must be profitable, and risks are only a matter of the integrity of the businessman, so the requirement to maintain capital is a constraint on the personal credit of the businessman. Another aspect is that China has not developed a more mature capital market. Lack of market tools. Pricing, trading and risk management of equity.

It has been more than 20 years since China’s securities capital market started in the early 1990s. Although it has begun to take shape, it has great impact on the entire social economy.The economic influence is still very limited. First of all, the threshold is high, and various debt and equity market instruments are only limited to thousands of listed companies. China's stock market itself lacks a money-making effect, making ordinary people's perception of equity investment even more negative.

As a tool for credit management, blockchain technology can build innovative trading models at low cost and automatically form a secondary trading market. It provides new opportunities to promote equity investment.

Bitcoin’s POW mining mode is a pure computing power game. If mining can be combined with business incubation, real capital functions can be achieved.

This is also the charm of the token economy. Through deterministic algorithms, ecological rights and interests are distributed, and at the same time, value is tempered through free market transactions. Convert future uncertainty into capital value. Form consensus on new wealth.

IV Is it true that Quark blockchain mining makes money?

Absolutely false. People who only make a lot of money in silence are not publicized everywhere. The publicity is currently looking for you to take over the order. You see, you don’t want Bitcoin. Bitcoin is the first currency of the blockchain. Currency is the right of a country’s bank. Bitcoin is too harmful to various countries and banks. They are all resisting. From the current trend, blockchain currency does more harm than good. However, blockchain technology is still very promising but not currency.

VI Is How to Make Money with Blockchain a Scam?

It is not a scam. Generally speaking, the current blockchain is still in its infancy, and many projects have not yet been implemented. Only those who respect the law of growth can Only by cultivating it step by step under certain conditions can it gradually mature. Technology is neutral, but it is human nature that determines the direction and outcome of technology. How blockchain and digital currency will develop in the future depends on the values ​​​​and civilization of the controller.
Blockchain can allow you to make money in this industry, but it can also make you bankrupt. Therefore, I would like to remind users that they need to be cautious when investing. Don’t let yourself get involved without making money, and the gain outweighs the loss. There are also many blockchain scams. We must also be more vigilant to avoid being deceived and causing unnecessary economic losses.
Expand information
Pre-loan stage
Blockchain technology can first be applied to the logistics supply chain to help banks and other lending institutions more comprehensively and accurately grasp the real main business, transaction background, and financing of small and micro enterprises. Downstream affiliated enterprises, as well as their negotiating position in the supply chain, product sales, rhythm and path of payment, etc., on the one hand, help more asset-light, high-growth and high-quality enterprises obtain financing support through transaction bills, logistics documents, etc. On the one hand, it prevents problematic enterprises from falsifying their business background and capital needs to obtain loans.
In addition, blockchain can also be applied to the provident fund interconnection to help banks understand the actual payment status of social security, provident fund, etc. of shareholders, executives, and ordinary employees of borrowing companies, so as to reasonably evaluate the size of the company's personnel and operating conditions, and provide credit and loans. Provide sufficient basis for approval decisions.
Loan stage
Blockchain technology can be applied to corporate loan information review and mortgage and pledge review to help banks improve approval efficiency and ensure approval quality. In the financing process of enterprises, especially small and micro enterprises, they often need to provide contracts and other necessary materials. Paper-based contracts with multiple signatures and seals are not only inefficient, but also have a series of problems such as forgery, alteration, and false signatures, which bring problems to bank approval. Greater counterfeiting, fraud and credit risks.
With the support of blockchain technology, relevant real-name information subjects, orders and ordering processes, electronic contracts, agreement signing processes, subsequent supplementary agreements, and photo materials can be preserved in real time, and all stored certificates cannot be tampered with. Ensure that the bank quickly authenticates and approves, and efficiently resolves disputes when they arise. In addition to traditional real estate, other assets owned by enterprises and business owners, including bank financing and other financial assets, can also be used for transfer and pledge, becoming a qualified basis for credit enhancement that can be accepted by banks, improving the availability and immediacy of corporate credit. .
Post-loan stage
Blockchain technology can be applied to the timely assessment of an enterprise's production and operation status and ability to perform repayments, helping banks to effectively grasp credit risks and adjust post-loan risk control strategies at any time. In past business practices, banks often neither fully understand the true market value of mortgages and pledges, nor can they well judge the impact of an enterprise's operations in warehousing and exiting on the market value of remaining mortgages and pledges. The ability to control new loan types such as warehouse receipt pledges is relatively low.
After switching to digital warehouse receipts supported by blockchain technology, product quality, quantity, specifications, photos and other information can be completely and standardized on the chain, authenticity and traceability are fully guaranteed, and banks can technically prevent Enterprises and warehousing institutions fabricate warehouse receipts and inconsistencies between warehouse receipts and warehouse entry and exit information to ensure that post-loan management is effective. In addition, information such as factory buildings and office building leasing of borrowing companies can also be fully shared with banks, upstream and downstream enterprises and other intermediary service agencies through blockchain technology, minimizing the risk of money being lost and other issues such as "people leaving the building empty".

Ⅶ Can anyone tell me whether you will lose money in blockchain transaction mining?

Losing money is possible under any circumstances. There is no such thing in this world. Investments that are 100% sure to 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.

Therefore, any industry has certain risks, and only when you devote yourself to this industry, that is, after you have an in-depth understanding, will you know the risks involved, and you You need to take 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.

Ⅷ Is mining reliable? Can you still make money by mining Bitcoin? An old miner tells you

When it comes to blockchain, I think blockchain projects are really The only way to achieve great results is within the next 3-5 years. You will either be recognized by the world or eliminated by the world. If you want to make money all the way by relying on those random projects on the market, it may not be realistic. Within 5 years, you will definitely There will be a huge wave of rectification, which will only lead to more and more formalization and uniformity!

There are many many projects on the market. Cut a wave of leeks cut a wave of leeks. However, the people who really make money are really small and less! So why are so many people willing to try and do it? It is indeed because many players make a lot of money! ! ! And those who really make money are often those project parties! I have been in the industry for four years and have been cheated many times and lost all my money! But I also encountered good projects and made my first pot of gold in life! ! This is also the reason why I chose to be a miner first. Anything that can create a legend must also have its merits, and Bitcoin’s merit lies in the blockchain. Not long ago, the People's Daily published a full-page report on blockchain. From the research on the concept of blockchain, the estimation of blockchain development trends, and being a leader in the digital economy, it called on the national government to conduct research on the region. Blockchain technology is strongly supported. No matter which angle you look at, it is certain that blockchain is constantly receiving official attention and has penetrated into the economic circle with great momentum. When Bitcoin was first designed, a mining time of 140 years was defined. There was a long experimental time for basic technology research and development and iteration. The current progress is beyond expectations. If all the mining was completed today, I believe many People would think that its price has soared a long time ago (many Bitcoins are mined out and put into the market every day, suppressing the price of the currency)). However, it has only been digging for eight years so far! It can also be said that it has just begun! The computing power of the entire network has grown very rapidly. At the beginning of 2017, the computing power of the entire network was only about 2E. By the end of 2017, it had exceeded 20E, an increase of about 10 times in one year. Now when calculating mining income, I use a 2% increase in each cycle (about 13 days). If it grows at this rate, it will increase to 5 times in one year, that is, the computing power of the entire network will increase to 28E in June 2018. However, in less than June, the computing power of the entire network has exceeded this value, which is a very large increase.

Are so many people really optimistic about mining?

In the Bitcoin operating rules, every time a block is created, a certain number of Bitcoins will be generated. (The act of creating blocks is called mining.) On average, every four years, the number of Bitcoins generated per block will be halved. It is expected that by 2140, all 21 million Bitcoins will be "produced". That is, as time goes by, the cost of generating new Bitcoins will become higher and higher. It will become increasingly difficult to mine a new coin. Mining output is related to only two variables: mining difficulty and mining machine computing power. The output is inversely proportional to the mining difficulty and directly proportional to the mining machine's computing power. As the difficulty continues to rise, the more mining machines there are, the more Bitcoins can be mined every day. If you don't take action, it will be too late!

Of course, many people ask, if mining returns are low, it’s because you don’t understand mining! Dig first and hoard first, then sell when the price of Bitcoin rises. It is definitely a direct currency speculation, the cost is much lower! ! ! Mining belongs to the level 1 market! In other words, mining belongs to the manufacturer. Do you think the goods sold directly by the manufacturer are cheaper? Or is it cheaper in the supermarket? ? Although the price of Bitcoin has not risen very much recently, the income from mining is still very considerable! ! The real opportunity to make money should be in 2020, so all miners, please save your Bitcoins and ride the rocket together next year! !

In the currency circle, playing with digital currencies and making money rely on opportunities. Opportunities are given to you. If you are not sure, you will just sigh~~Why did you dig it in the first place? Mine can be said to have no reason to hesitate! In 2009, Bitcoin was launched, and it cost 2 cents a piece. Now it costs 60,000 yuan. Who would have thought it? I have been studying mining for many years, and it can be said that there is really zero risk!

Of course, the future value increase of Bitcoin is the key, and investment is a probabilistic event. How long can this game last? I can only say that the sooner, the better! ! ! Can Bitcoin rise to the point where one coin per villa? The answer can only be left to tomorrow.

Ⅸ HandDoes mobile mining really exist? Is it reliable?

Mobile mining does exist, but in the past five years, mobile mining has been unreliable. Most of them were cut off from leeks. Now you can get profits by just tapping the screen. This is not mining, but a small game. Mobile phones are not currently used as blockchain nodes. If you really want to build a blockchain node, it will cost a lot of money on your mobile phone. It needs to run at high speed 24 hours a day. Today's mobile phones really can't handle it. Anyone who knows about virtual mining knows that mining requires a lot of computing power. A mere mobile phone is fine if it is some unpopular currencies. Popular coins such as Bitcoin and Ethereum can only be used by a mobile phone. It is difficult to mine, so if you want to mine, you still need to find a professional mining machine to mine, so that the probability of mining a block will be greater. There are many mining machines on the market now. You can consult with them to buy the most cost-effective mining machine. For example, professional mining companies such as Shilian Mining can help everyone realize the freedom of mining▫⋅
