Computing power of Bitian continental ore pool

1. mining pools are arranged according to computing power. For example, the computing power of digyi mining bitcoin mining pool accounts for about 4% of the total network computing power, ranking among the top ten mining pools in the world. The four technology blockchains are relatively good.

2.

Mine pool refers to:

as the computing level of the whole bitcoin network continues to rise exponentially, a single device or a small amount of computing power can not get the block reward provided by the bitcoin network on the bitcoin network

after the computing power of the whole network has been improved to a certain extent, the low probability of getting rewards has prompted some geeks on "bitcoin talk" to develop a method that can combine a small amount of computing power and operate jointly, and the website established in this way is called "mine pool"

extended data:

the existence of the mine pool reces the difficulty of bitcoin and other virtual digital currency mining, reces the mining threshold, and truly realizes the bitcoin mining concept that everyone can participate in

but its disadvantages are also very obvious, because computing power is connected to the mine pool. As a mine pool, it will have huge computing power resources. In the bitcoin world, computing power represents the bookkeeping right, and computing power is everything. If the computing power of a single mine pool reaches more than 50%, it will be easy to launch 51% attacks against virtual digital currencies such as bitcoin, The consequences are very terrible:

the mine pool can make the mine pool with 49% of the remaining computing power have no harvest, instantly quit the competition and go bankrupt. The mine pool's computing power exceeds 50%. If 51% attack is launched, it will easily occupy all the effective computing power of the whole network

3. It's not so easy to close. I used to use the fish pond all the time, but the fish pond didn't welcome me as a small miner. Later, I turned to ha Yu miner, and the calculation power of the mine pond was not low
the biggest advantage of using hayu mining pool is that as long as you connect to the mining pool, you can use the mobile app to monitor the mining machine, withdraw cash every day, and the number of users has been increasing, and there are online customer services to answer any questions you have!

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

At present, bitcoin needs to be g by professional mining machines. The global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin

according to the current speed and the number of bitcoins, it will take three months to get a bitcoin if a computer is kept in a 24-hour state of operation

extended data:

because the current bitcoin mines use special bitcoin mining machines to mine. The computing power of an ant S9 miner is 13.5th/s, which is equivalent to the sum of the computing power of 7500 1080ti graphics cards. A medium-sized mine has hundreds of such miners

the instry of bitcoin is not very good either, so you'd better not dream of becoming rich overnight with bitcoin. Now many countries have issued policies to suppress the rise of bitcoin prices. Some countries even refuse to dig bitcoin. Many bankers and economists are disgusted with the emergence of bitcoin

6. After many cloud computing efforts, we found that the service of Weiyou cloud platform is good, there are physical mines, and there are also field visits. Safety is the first thing, and we finally choose Weiyou cloud platform.

7. Renren mine brand is older, the strength of investors is better, there are mines in the world, and the risk is greater than Xiaolu

8. 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.

The root of the contradiction between the two founders of bitmainland comes from the dispute over the company's development route. The core is the strong disagreement on whether to develop AI chip business. It has been reported that Wu Jihan and Zhan ketuan had separated peacefully in the first half of the year, and Wu Jihan was far away from the management of the mainland. Wu Jihan, together with some core technicians, founded a new company dedicated to the construction of blockchain infrastructure, whose business includes digital currency exchange, mine pool, etc. It is reported that bitmainland has also invested in Wu Jihan's new company, and Wu Jihan continues to hold shares in bitmainland

At present, Wu Jihan and Zhan ketuan have completely changed their face. With Zhan ketuan's strong character and the position of the largest shareholder, it is estimated that the internal strife will be difficult to calm down in a short time, and it is impossible to ensure that there are any previously unknown or even illegal insider reports; Secondly, unlike Jianan Yun, bitmainland not only proced mining machines, but also issued virtual coins, which became the biggest obstacle to its listing in the United States
