Ant miner is the first cryptocurrency miner brand in the world with a market share of about 70%. The mining machine is developed by bitmainland and has a patent in mainland China. At the beginning, ant miner had only bitcoin miner. Later, its business expanded to other cryptocurrencies, such as Ethereum, dascoin, Leyte, Monroe, etc

ant mining machine adopts ASIC chip designed by bitcontinental, which is proced by TSMC. All chips are made of BM prefix. Each miner has three to four circuit boards, and there are dozens of chips on the circuit board. Therefore, each miner can only be used to mine one or more cryptocurrencies using the same algorithm

ant mining machine needs special mining software, and can not use third-party software. In addition, because of its high power, the ant miner also needs to be used with a special fire ox

The ant miner is often criticized as monopolizing the cryptocurrency mining instry e to its 70% market share, which goes against the purpose of cryptocurrency decentralization. Because Monroe was worried that the mining machinery would monopolize the mining market, Monroe announced to change the mining algorithm a few days after the launch of Monroe (X3 model) despite the opposition of Monroe community, so that all mining machinery could not be used to mine Monroe. Bitcontinent also encountered the failure of its first proct here

the ant miner will use a lot of electricity and proce a lot of waste heat in the process of operation. This leads to a large amount of electricity being consumed for mining or cooling, causing a lot of social criticism. Too much ant mining machine at the same time also led to fire and power failure, causing social inconvenience

5.

At the end of March this year, bitmainland launched an ant miner X3 based on ASIC, which is mainly aimed at Monroe coin (XmR) and cryptonight algorithm dependent cryptocurrency. Monroe coin immediately issued a counter statement that it will change the core algorithm to fight against the invasion of ASIC computing power

what would be the result if it appeared in the world of digital cryptocurrency? That is, the wrong calculation results may be brought into the whole network without being discovered

More importantly, if a "calculator manufacturer" monopolizes the calculator market, it can also deliberately proce this kind of calculator with errors to change the mathematical rules

after all, the "calculation" in the field of crypto digital currency is not as simple as 1 + 2 + 3. You can't compare paper currency with special currency by hand

the practical significance of computing power monopoly in mainland China

we have learned about attacks based on 51% computing power in various articles

but the reality is that although the global power of 78% was in Chinese mainland, fortunately, they were scattered in different pools and controlled by different people. p>

although all POW based cryptocurrencies have the risk of being attacked by 51%, few people can really launch attacks e to the dispersion of computing power

but what if the miners themselves don't want to attack, but the mining machinery manufacturers attack

still using the analogy just now, although each miner subjectively wants to do the problem checking independently, their calculator is manipulated remotely and gives consistent wrong answers. This may pose a great threat to digital cryptocurrency

however, the manufacturer with the absolute voice of mining machinery had such a problem in mainland China

in April 2017, the back door of antbled came out. Although this is described as a "vulnerability" in Chinese, antbled is more like a function that has been implemented and designed

anonymous people found that after an ant miner made by bitmainland was connected to the network, it would communicate with a domain name held by bitmainland on a regular basis and return the miner's serial number, MAC address and IP address to bitmainland's server. If the server of bitcontinent gives a negative signal, the miner will stop running

although bitcontinental responded that they could not shut down any mining machines that did not belong to them. However, the bitcoin core team has proved in experiments that this function has no verification. Anyone can shut down mining machines by forging DNS - but it also means that bitcoin mainland has the ability to shut down any sold mining machines

After

, bitcontinent fixed this "loophole", but it caused heated discussion in the community. This has also set the tone that almost all pow blockchain communities are biased against mainland China

a few months later, under the leadership of bitcontinent, viabtc g out the first block and made a hard bifurcation with the blockchain of bitcoin. From then on, bitcoin BCH (bitcoin cash) appeared in the world

will the monopoly of mining machinery destroy the distributed system

facing this problem, we should have a clear answer now. That is, the monopoly of mining machinery will certainly affect the safe operation of pow digital cryptocurrency

the problem is not whether bitcontinental and its founder Wu Jihan are trustworthy, but that one of the values of any blockchain system is to operate safely without trust in any single company or indivial

even if the ASIC miner is not monopolized by bitmainland, the ASIC miner itself will increase the concentration of computing power

the ASIC used for mining has great requirements for ventilation, power and site, and has no use except for mining. At the same time, the calculation difficulty of the whole network is increased e to the powerful computing power

as a result, it is very difficult for external players to start mining in the next software on the computer as they did five years ago. And the recent centralized exchange is caused by frequent black incidents, which also proves that concentration in this unregulated market will definitely lead to insecurity

assuming that the bitcoin network runs on top of one million miners, no one can shut it down. And if the bitcoin network runs on 20 large mines, it's much easier to shut it down

and by the end of 2017, 78% of the effort was concentrated in mainland China, which led to a real possibility of Chinese mainland regulators' launching a deadly attack against the special currency. p>

moreover, most of the scenarios of using digital cryptocurrency are related to "decentralization". Once centralized, it means that these scenarios no longer exist. It turns a project that might have value into a pure waste of computing power

Then, what measures should we take in the face of this situation

first of all, as the project side, it may be time to give up the pure POW mechanism. In fact, in many projects of issuing cryptocurrency, especially in asset securitization projects. Similar to the concept of stock in the real world, POS itself is more reasonable than pow

in the media that don't know about blockchain, we often hear such words as "bitcoin wastes a lot of computing power and has no value", which is reasonable to some extent. It is difficult for a POW based blockchain to bind the value of the project itself to the issued digital cryptocurrency - because the real value behind the price of the currency does not come from the project, but from the cost of maintaining computing power

and the hybrid mode of pow + POS is more like the future. In the hybrid mode, both coin holders and miners can participate in the major decisions of this community. If a decision is widely accepted, the blockchain will be soft forked to the latest state without excessive intervention of developers, and there will be almost no private resistance of miners or mining machines

secondly, as a retail miner, if you are still digging a pure POW mechanism currency, you should unconditionally support the bifurcation activities initiated by the community to resist the ASIC mining machine, even if it will lead to the failure of your mining machine

this may sound contradictory, but in the long run, it is better to promote the reform of the community and get more benefits in a currency controlled by the monopoly of computing power. Because in many conflicts between computing power and community in the past, the ultimate result is that the computing power owner will forcibly keep the old algorithm to hard fork the blockchain

just like Eth and etc, the classic Ethereum (etc), which belongs to the computing power master, has lost the support of developers and become an air coin with no vitality and impossible to develop applications

as a retail leek, you should be careful to trade the non mainstream digital currencies (except bitcoin) supported by bitmainland mining machinery, so as to avoid falling into a blockchain in which bitmainland controls the computing power completely

finally, if you are bitcontinent, what should you do

bitcontinent's goal is to become Intel, AMD and NVIDIA, make greater contributions to the whole computer instry, and become a great company, not just entangled in the immediate interests of mining

Wall Street financiers have long seen through the violence brought about by NVIDIA's video card mining. The rise and fall of the company's stock price has been consistent with the price of bitcoin, and even affected by the digital currency market. Citron, a well-known short seller, has recently been bearish on NVIDIA, arguing that the company has focused too much on providing services for digital currency miners rather than on serious businesses such as artificial intelligence, games and driverless driving

the mission of chip manufacturers is to provide more powerful chips to drive more intelligent services, and finally contribute to the real world, rather than become monopoly tycoons in the virtual world. When we no longer enter the gate of the virtual world, the only thing left is a deserted land

in an interview with US media last year, Wu Jihan disclosed that he would make an IPO with a market value of billions of dollars. As a company about to go public, bitmainland should not only be responsible to investors, but also accept investors' questions about the sustainability of its business. "If your mining machinery goes public, it will encounter a fork, what should you do?"

and this question, which needs to be asked after the listing, has already appeared: the current price of the split coin xmo after the Monroe team split is $7.50, while the current price of the real Monroe coin XmR is $194, and the split coin is completely abandoned by the Monroe community

before bitcontinent becomes the name of all blockchain communities, we can rely on the huge amount of capital accumulated in recent years to transform into an artificial intelligence chip company along the previous plan, rather than continue to develop a variety of digital currency mining machines to extract the last drop of oil before the ecological collapse

6. I can't find one in a day. Now bitcoin is not what it used to be. And bitcoin is now banned by more and more countries

7.

No illegal
in the bitcoin risk notice jointly issued by the people's Bank of China and other five ministries and commissions at the end of 2013, bitcoin is clearly defined as a special Internet commodity, and people can buy and sell it freely at their own risk. But it denies the monetary nature of bitcoin< The Article 143 of the general provisions of the civil law stipulates that "the civil legal act with the following conditions is valid:
(1) the actor has the corresponding capacity for civil conct< (2) the expression of intention is true< (3) it does not violate the mandatory provisions of laws and administrative regulations, public order and good customs. " The announcement of the seven ministries and commissions is neither a law nor an administrative regulation, and can not be used as a legal basis for judging whether a civil juristic act is valid or not; The law does not go back to the past. Therefore, the bitcoin transaction has legal effect, and the bitcoin obtained from the transaction is protected by law. Therefore, legal disputes arising from trading activities, including civil or criminal cases, should be subject to jurisdiction. Courts or public security organs can not refuse to accept bitcoin because they think bitcoin is not protected by law

transaction mode

bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free

a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it does not need to exchange information online when generating address, so it can be offline [2]. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"

the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet

after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions

The soaring price of bitcoin will aggravate the shortage of chips and even threaten international security

after the end of February, bitcoin reached a high of US $57000 again today. At about 3 am on March 11, the price of bitcoin surged to more than US $57000, reaching as high as US $57277, a new high in the past two weeks, according to bitfan, a website of cryptocurrency market

However, the price of bitcoin continued to decline. As of the press release, the latest price of bitcoin was $55908.51, up 2.15% in 24 hours, and the market value returned to $1 trillion

However, in the view of some financial economists, bitcoin's surge is not something to celebrate. On March 11, Alex de Vries, a financial economist, quantified in Joule, a journal of Cell Press, how the soaring price of bitcoin exacerbates energy consumption and global chip shortage, and even threatens international security

extended information:

the price of bitcoin has risen sharply, and the miner and graphics card have been "hard to get one stock"

according to the official website of bitcontinental, the head miner, the relevant bitcoin miner has been sold out, and the delivery time has been postponed to October 2021. In the second-hand market, mining machine can easily resell to the official website more than 2 times the price. Just take the ant miner s1995t owned by bitmainland as an example, the reporter found that the retail market price of the machine whose official website price is about 20000 yuan can easily exceed 50000 yuan

as the "iron pick" in the hands of bitcoin miners, the graphics card is seriously affected. A large number of people in the instry believe that the rise in the price of graphics cards in recent years, and even now that NVIDIA's RTX 30 series and AMD RX 6000 Series graphics cards are "hard to get one card", are closely related to the huge demand of bitcoin miners for graphics cards

9. Hello, miner trusteeship,
if there are only one or two miners, you can choose to dig at home, rent an empty house in a slightly larger remote point, and use it as a special machine room, so that the miner will not disturb the people and it is convenient for you to visit at any time
if there are dozens or even hundreds of mine machines, it is recommended that you choose mine trusteeship. First, the electricity charge of mine trusteeship will be cheaper than that of indivials, and there are special personnel to take care of mine machines. The inconvenience may be that most of the mines are located in Northwest and southwest provinces, which may not be convenient for you to understand the actual situation, but you can also choose the background software to monitor your own mine machines, The selection of specific mines can be evaluated according to the quotation
if you don't know much about this area before and don't have a miner, you can choose to buy cloud computing power. This kind of miner is only used in a different way. The ownership of the miner doesn't belong to you, but is rented to you

the advantage of the mineral machinery trusteeship lies in the fact that it is not easy to manage; Annual regular electricity subsidies, cheap electricity&# 130; 24 hours a day without power cut to dig money; There is operation and maintenance technology in the mine 24 hours on call, problems can be solved immediately&# 132; If the power board is broken, it needs to be returned to the factory. The company will have machines to make up the power. However, it is suggested that when you choose a mine, you should consider the quotation of mine management fee and electricity fee
if you have any other questions, please ask me. I hope I can help you, thank you!

10. How to mobilize the enthusiasm of service center staff belongs to the category of management incentive theory, which can be implemented according to the following six steps< First, practice the premise and principle of motivating employees. Incentive theory reveals that the premise of effective incentive is to find out the actual needs of each employee, the expectation and value for the future, and the evaluation of the current situation of fairness
2. If you want to motivate others, motivate yourself first; Require employees to strive for excellence, leaders must first have the determination and confidence to strive for excellence. In this way, leaders can infect and inspire everyone with an invisible personality charm
3. Fair. Justice is fair and reasonable. It requires leaders to treat their employees equally, and not to be intimate with them. Whether leaders are fair or not has a fundamental impact on the enthusiasm of employees
4. Trust. Lack of trust in an organization can be fatal in the end. The trust in any kind of incentive measures depends on leaders' trust in their subordinates and subordinates' trust in leaders. Trust is both sides, the trust of the unit will not last long. In an environment of mutual trust, every employee will become an important worker
5. The dialectical principle of material incentive and spiritual incentive. From the incentive theory of management science, we can see that material incentive is the foundation and spiritual incentive is the key. In the current economic situation of our country, the demand for health care has been basically solved, and the incentive measures are more and more important. At the same time, we should not ignore the fair theory about incentive measures. Leaders should pay attention to the fairness of material interests and spiritual treatment, otherwise it will affect the enthusiasm of employees
6. The principle of comprehensive application. There is no superior or inferior between any two kinds of incentive measures, only whether to adjust measures to local conditions. The actual process of incentive cannot be fully realized by one method. In a certain period of time, there is often the maximization of the effect of some incentive measures, but it does not exclude or do not need other incentive measures. Therefore, to effectively mobilize the enthusiasm of employees, we must comprehensively use various incentive measures to overcome the singleness.
