Monroe coin in China
their service is very good
because those who come in after mobile phone mining will be cut leeks
precautions:
1. In the past two years, various myths about blockchain "overnight wealth" have been constantly staged, and "mining" cryptocurrency has become a new trend of wealth, and mobile phone mining is becoming more and more popular
2. There will be special mining machines for real mining. After all, every mining machine is not cheap now. Mobile phone automatic mining can be obtained at a very low price. What you dig is not bitcoin. Basically, the counterfeit coin you send is not worth money. At that time, you will still be cut leeks
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 P>
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 P>
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

mobile phone mining is to attract traffic by speculating the value of the virtual currency. After obtaining the traffic, it can be realized by advertising or colluding with script authors. It can stabilize the morale of the army and a group of people by purchasing virtual currency or other means. It can also attract others to join the gang through high invitation and reward, The next batch of leeks came happily
at present, e to the rise of digital currency mining, it is generally necessary to connect to the mine pool. For example, if you want to dig Monroe coins, you need to connect to the Monroe coin mine pool. The other is that some companies develop their own software, and then let others hang up their mobile phones to mine. This is almost deceptive. It is to use the concept of blockchain to hype some worthless coins issued by itself, such as token. Some of them are even directly similar to the points of traditional websites, that is, a number stored in the database, which has nothing to do with blockchain technology. This is purely to trap people for money
precautions:
1. In the past two years, various myths about blockchain "overnight wealth" have been constantly staged, and "mining" cryptocurrency has become a new trend of wealth, and mobile phone mining is becoming more and more popular
2. There will be special mining machines for real mining. After all, every mining machine is not cheap now. Mobile phone automatic mining can be obtained at a very low price. What you dig is not bitcoin. Basically, the counterfeit coin you send is not worth money. At that time, you will still be cut leeks.
the most familiar and easy to understand is Bill Gates and his Microsoft Windows operating system. Windows has entered into thousands of households and instries. People have improved proctivity and created great value through this computer program. As a result, Microsoft even once became the company with the highest market value in the world
What about bitcoin, also a software with high "value"“ In fact, many people want to know what kind of value bitcoin brings to people and things, thus supporting the consensus on bitcoin and steadily boosting its market value to more than 1 trillion< Miners and other participants in mining ecology
to put it simply, bitcoin mining machine is a machine that keeps making profits for miners. It can lay eggs like a chicken and proce value, and even go to the road of ten billion rich. This is the value of bitcoin for miners, mining airport operators, mining pools (service providers) and other people who participate in the upstream and downstream of mining ecology. Miners are the most important participants for bitcoin, and for miners, the miner that can proce bitcoin is a "hen" that can lay golden eggs. Although the journey of mining is not as simple as expected, and it's really a bit like opening a "chicken farm", which needs to provide all kinds of suitable environment, maintenance and "food" (energy) transportation to successfully proce "golden eggs" for profit, the miners are attracted by the benefit distribution mechanism of bitcoin, and new miners are constantly joining in
2. User
the full name of bitcoin system is a peer-to-peer e-cash system, so for users, it can be used to initiate transfer transactions. So why use it to transfer money? To put it bluntly, it means saving time, effort and money. Bitcoin does not need to transit through banks, third-party payment companies and so on to reach the other party's account directly, which eliminates the processing time, operation manpower and fees of third-party institutions. The fees collected by banks and other financial institutions through financial services can show how huge the fees are. In fact, many people don't understand the concept of the third-party guarantee agency very well. Most of the time, we transfer money for free, because in the credit society, small amount transfer is completed through the credit line between different financial institutions, which is not a real transfer
3. Savers and speculators
because bitcoin has value in use, and has many high-quality characteristics, especially like gold, and some of its characteristics are better than gold. It also has the function of "partial" risk aversion and value saving like gold, so it is graally regarded as gold, an international hard currency, and began to be hoarded by many people
4. People in poor and backward or "turbulent" areas
e to the low transfer cost and short time required by bitcoin. In many poor and backward countries, there is no need to build expensive network infrastructure to transfer money through encrypted network. Bitcoin's infrastructure is built by miners all over the world, which does not need the burden of poor countries' governments. There is no intermediate cost for payment and payment of salaries, which can save a lot of money< There are many such corners in the world, which are remote but rich in mineral resources or natural resources such as water conservancy and wind power. For example, there are many coal mines in some areas, but e to the high transportation cost, they can not be transported out. At the same time, e to the lack of people, the power generated by thermal power, hydropower stations and wind farms built in these areas is very surplus, and the economy of these areas is often relatively backward. At this time, they need and welcome miners to settle in. Miners not only bring a lot of jobs, but also convert the local surplus energy into power resources, and then generate a lot of income through bitcoin mining. This is actually equivalent to storing the energy value that might have been surplus and wasted through bitcoin network, and then paying the local government and people through electricity charges, Drive the local economy<

the air is dirty and the bath is dirty
in a bath center located in Taihang District of Taiyuan City, a bad smell comes from the bathroom. It turns out that the bathroom and toilet are connected as a whole. In addition, in winter, the windows are closed and the air is not circulating, so the air in the bathroom is dirty. However, what is even more unacceptable is that the water in this bathing center is cool and hot“ It's strange that you don't catch a cold when you wash it like this. " Said a customer who came to take a bath. Take another look at the water in the bath. On it, there are still oil stains left by the bather after washing. However, the bath worker still takes the dirty water to wash the customer's body. A customer who asked for a bath could not help but ask: "can this kind of cleaning be cleaned?"
low price and equipment in disrepair
the price tag of the dormitory bathhouse of the weaving factory located in Changfeng street is: 3 yuan for bathing + sauna, 3 yuan for rubbing bath and 8 yuan for massage. Such a low price will naturally attract many customers. Entering the bathroom, the scene is disappointing. Due to the long-term corrosion of humid air and water, the wood board in the steaming room has been moldy. In the corner of the room, there are electric stoves piled with hot coal and exposed red wires. However, only a few thin wooden blocks are used to block the stove emitting high temperature. Once someone accidentally touches it, it is easy to be scalded
more than one customer shared a towel
in the process of taking a bath, one out of every three people asked to take a bath. However, the reporter noticed that every customer was given the same towel by the washman. When the reporter said whether it was sanitary or not, the washman had his own understanding: "Oh, who still uses my towel now? It's so dirty. People take it with them. " At this time, the customer said to the bath worker, "can you give me some soap?" The bath worker took up the customer's soap and put it on the towel, daubed it all over the customer's body, then opened his mouth and said, "one piece." At this point, the customer realized that the original 3 yuan only for "rubbing bath".
