Mining transformation
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 rulesafter 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 situationfirst 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

Cloud Computing: Top 10 development trends
here is a list of top 10 forecasts of the development trend of cloud computing instry in 2019 made by practitioners, analysts and enterprise decision-makers in the cloud computing instry for your reference<
participating in IDC circle: Top Ten Trends of cloud computing in 2019: cloud has become the main way to obtain artificial intelligence
1. Extensive use of intelligent decision-making has become an advanced symbol of enterprises
artificial intelligence has stepped out of the "entertainment world" and started to widely assist human decision-making in enterprise operation
in the future, whether an enterprise is advanced or not, one of the main measurement indicators is the proportion of intelligent assistance employees (not only serving executives) to make decisions. Cloud is no longer an issue discussed by technology circle, but more concerned by enterprise decision-makers
it is more urgent for enterprises to use artificial intelligence and other technologies for business innovation than ever before. At the same time, cloud based intelligent business will also trigger organizational change
2. Enterprises will graally give up the self built it infrastructure and move to the public cloud, resulting in "cloud based native enterprises"
the infrastructure of Netflix, an American video website, has been relocated to Amazon AWS. A small number of Chinese enterprises have realized such overall cloud relocation in 2018, and it is expected that a large number of cases of such overall cloud relocation will emerge in 2019
the cloud of means of proction means the opening of a new era
3. Cloud has become the most important path for enterprises to acquire AI
cloud naturally solves the unification of enterprise data and technology, and constitutes the most important path for enterprises to acquire AI capability< At present, public cloud platform has become the most important channel for customers to obtain AI services at low cost
in the business field, artificial intelligence technology that has been verified by cloud service providers' own business is favored by enterprise decision makers<
4. Hardware cloud service providers graally bid farewell to the public cloud market
in 2018, the traditional hardware start-ups encountered collective acclimatization in the era of public cloud
IBM's share of cloud computing has declined. Before that, HP, Cisco, Fujitsu and other enterprises had setbacks in entering the public cloud market with the help of open source openstack technology. The analysis shows that the hardware manufacturers' failure in the public cloud market lies in their failure to understand the nature of cloud computing
the essence of cloud computing is not a "computer" but a service. In addition, such enterprises are almost perfectly wrong with the Internet era. As a result, the hardware genes of the above-mentioned manufacturers are so powerful and the existing businesses are so successful that they are faced with the "innovator's dilemma"
5. The public cloud market is further concentrated
according to the statistics of authoritative market research institutions Gartner and IDC, four manufacturers, including Amazon AWS, Microsoft azure, Alibaba cloud and Google cloud, have become the leading forces in the global public cloud market, and their revenue growth rates are far faster than the average growth of the instry
Goldman Sachs, a Wall Street investment bank, predicts that Amazon, Microsoft, Alibaba and other giants will occupy about 84% of the core cloud computing market in 2019. These companies are significantly ahead of their competitors in talent, technology, operation, service, capital, ecology and other aspects. It can be predicted that the global cloud computing market concentration will be further improved in 2019, and will be more significant in the next few years
6. Enterprises prefer full stack solutions
in the past year, with the accelerated penetration of intelligent technology in the business field, many enterprises have realized intellectualization in some business links
however, more and more CEOs prefer comprehensive solutions than artificial intelligence technology to enhance a certain business or link. This kind of solution can not only realize the data of the company's business, but also provide a set of verified intelligent tools to help enterprises realize intelligent decision-making
in 2019, more comprehensive intelligent solutions will continue to appear and be welcomed by the market
7. Enterprises embrace cloud computing for security
in the past, security has become an obstacle
when many enterprises choose whether to go to the cloud, the most important concern is security, not only for their own information security, but also for the stability of business systems. However, with the digital transformation of the whole society, all kinds of business operations of enterprises will inevitably touch the Internet. In order to seek business security, they begin to become the driving factors for enterprises to actively go to the cloud
cloud computing manufacturers have a strong security team to serve too many types of customers, which can enable enterprises to obtain a strong security protection capability at low cost, which has changed the investment habits of enterprises in security in the past< After more than 10 years of development, cloud computing technology has graally matured, and the enterprise's acceptance of cloud computing is also further improved
as cloud computing can bring obvious utility to enterprise IT operation and business innovation, cloud computing has become the norm of enterprises
in 2019, the whole society will put more and more budget into the field of cloud computing, which will further enhance the proportion of cloud computing in the overall it expenditure. Goldman Sachs, a Wall Street investment bank, predicts that the market penetration rate of cloud computing will exceed 10% for the first time in 2019, and it will jump to 15% by 2021. This means that cloud computing will further erode enterprise IT spending and enhance its influence in the IT market< M & A activities in cloud computing instry will be more frequent
in 2018, there are many large-scale M & A transactions in the field of cloud computing, which are divided into different fields such as chip, security, artificial intelligence, developer community, cloud solutions, etc
in order to maintain the rapid growth, the mainstream cloud computing manufacturers need to launch more high value-added procts or services, and constantly expand the scale of paying customer groups. Mergers and acquisitions have become a means to achieve rapid results.
In the bear market of the past few days, until these days, the price of currency is graally stable, and the speculators can finally relax
as the saying goes, bull market sells money, bear market mines, but the real bull market is expected to come slowly
now, only mining can ease the mood, Haru miner , mining anytime and anywhere, Xiao mining entry artifact to understand
don't underestimate the instry you don't know about.
in this area, coach Qian He.. If you are an expert, you might as well ask her for advice
maybe it can help you
because the business of Internet cafes in Vietnam is very poor, and under the impact of the epidemic, there is no attendance. For a long time, there is no business here, so the Internet cafes in Vietnam use rtx3080 graphics card to mine, that is, to find bitcoin the price of bitcoin has gone up by leaps and bounds, reaching tens of thousands of dollars a piece, making a huge profit. And the owners of Internet cafes also feel that after they become mining instry, they earn even more than before. Bitcoin can be said to be one of the most popular procts now, and it may have reached an era of nationwide mining in the future
However, netizens are also very funny about the situation of Internet cafes in Vietnam. Do you think the Internet cafes in Vietnam are so miserable? To this extent. However, a lot of netizens said that they understand very well. They think that if they open an Internet bar, if they use the computer of the Internet bar to mine in their spare time, if they have attendance, then they can be said to have the best of both worlds< however, if you want to dig bitcoin, it also consumes a lot of power, so many netizens are worried about whether the surrounding areas will be cut off by bitcoin"ADC mining" is a network pyramid scheme, the relevant suspects have been arrested by the police
on August 29, 2018, the police of Jian'an District, Xuchang City, Henan Province, smashed a large network pyramid selling Gang, namely Hangzhou, which is suspected of "ADC mining" network pyramid selling. I'm clown Network Technology Co., Ltd. the picture below shows the police going to Jinhua, Zhejiang Province to check the cash involved
did not think of the police was that the suspect bought a villa worth ten million, which was used to hide the illegal income. The cash that the police seized at the scene was up to 1 billion 300 million yuan. p>
Hangzhou I am clown Network Technology Co., Ltd. first launched the "IAC", members join through the recommendation registration system, set a certain threshold, form a fixed up and down line relationship according to the recommendation relationship, take the virtual seed as the trading partner of members, and take the number of directly or indirectly developed personnel as the basis for member level promotion and reward
in June 2018, IAC scam was exposed, and IAC official team announced that it would transform ADC's new mining mode. ADC claimed that it was a global advertising communication system, and mining was ADC's operating system based on blockchain technology. It continued to go online again with the help of the new coat of virtual currency
extended materials:
IAC is the abbreviation of "I am clown". It is a platform that claims to help every ordinary clown realize his dream of creating wealth. In the end, it is just a MLM organization that aims to earn its own interests
According to the regulations on the prohibition of pyramid selling issued by the State Council, "the following acts belong to pyramid selling: organizers or business operators, through developers, require the developed personnel to pay fees or pay fees in disguised form by way of subscribing for commodities, obtain the qualification to join or develop other personnel, and seek illegal interests."the police remind us to invest cautiously and pay attention to risks
