the first category is familiar game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the first two types can be regarded as one, which is only a detailed difference in function. Since the end of 2016, the third type of digital currency has quietly entered our life, which refers to the digitization of currency. Digitization doesn't mean scanning. This is just like digital signature. Digital signature does not mean scanning your signature into a digital image, or using the touchpad to obtain the signature, let alone your signature. Digital currency is often mistaken for virtual currency. But virtual currency refers to non real currency. For example, when you play "Three Kingdoms" (game) or "grand Voyage", you have money, which is virtual, that is, the first and second categories we just described. Of course, the virtual money will also have its real value. For example, if you buy her / his account from another player, you can get all the virtual assets of that player, and then it will be much easier for you to continue playing. Virtual money is not necessarily digital. For example, children play games with pebbles as virtual currency
there are also obvious differences between the transaction rules of digital currency and virtual currency. In most cases, the value of digital currency is higher than that of virtual currency, and it needs more strict transaction rules to carry out transactions
the top three currencies of digital currency are BTC eth EOS
this is also a distributed (decentralized) digital currency. Unlike the sha256 mining algorithm used by bitcoin, LTC adopts scrypt algorithm. Scrypt algorithm uses sha256 as its subroutine, and scrypt itself needs a lot of memory. Each hash is used as the seed of the input, and then it needs a lot of memory to store another pseudo-random sequence to generate the pseudo-random points of the sequence and output the hash value. In the mining of BTC (bitcoin), it is not enough to rely on simple graphics card mining (it takes about ten to dozens of days to dig a BTC with general configuration graphics card). The emergence of various expensive mining machines has raised the threshold for ordinary people to get BTC through mining, while LTC has certain advantages in using PC graphics card mining This passage comes from Zhihu.)
compared with BTC, litecain has made a little improvement in technology. If BTC is gold now, LTC is silver for the time being
the biggest advantage of litecoin is that it can confirm the authenticity faster. The virtual currency is designed and maintained by Charles Lee. Bitcoin transactions need to be verified, and the average verification time is more than 10 minutes. Most transaction websites need 1 hour to verify. The average transaction confirmation time of liteoin is 2.5 minutes. Developers claim that shortening the verification time increases the practicability of virtual currency. The bitcoin mining efficiency of customized machine and AMD GPU is the highest, making it almost unprofitable for miners using CPU mining. Litecain's mining excludes GPUs and custom processors, so it doesn't rely too much on a small number of professional miners
ppcoin
ppcoin (PPC) was released on August 19, 2012, which has improved the original technology of BTC. Use proof of make and add the concept of coin age
ppcoin is a bifurcated project of bitcoin, which aims to achieve energy efficiency and maintain the best performance of the original bitcoin as far as possible. The unit price of ppcoin is US $0.22 and the total currency value is US $4 million
ppcoin does not have a fixed upper limit of money supply, but it does not mean that ppcoin has obvious inflation compared with bitcoin. Bitcoin can be compared to gold. The annual inflation rate of gold is about 1-3%. Although gold has no known upper limit of money supply, we still know that it is a reliable scarce commodity
ppcoin has two types of casting: work certificate and equity certificate. The coinage rate of working proof is affected by Moore's law, which depends on the doubling of our working proof ability. What we all know is that Moore's law will eventually come to an end. By then, the ppcoin of inflation may be close to the gold level. The annual maximum inflation rate of certificate of equity is 1%. At the same time, ppcoin's transaction costs were destroyed to fight inflation. So on the whole, the coin design of ppcoin is still a very low inflation design in the future, which can be comparable with bitcoin<
ppcoin's reward is similar to lottery, which will determine the winning probability according to the number of ppcoin held by miners. Sunny king, one of the founders, said that their design is based on a new concept of long-term energy efficiency
terracoin
terracoin (TRC) was released on October 26, 2012, with a total currency of 42 million. The speed of each block is 2 minutes, slightly faster than LTC. There is not much special in technology, similar to the proction of BTC halved every four years
however, the operation team seems to have a strong business background and may be better than other bitcoins in circulation. The development of virtual currency is getting more and more attention. Now some teams with business background will accelerate the development of virtual currency
namecoin
namecoin is a distributed domain name system based on bitcoin technology. Its principle is the same as bitcoin. The first release date of this open source software is April 18, 2011
namecoin is generated from an original block which is different from bitcoin's main trading block. It uses a new blockchain, which is independent of bitcoin's blockchain. Because it is based on bitcoin, the security, distribution, robustness, encryption and migration of domain names are guaranteed mathematically. You can dig bitcoin and namecoin at the same time
this project was discussed and proposed by bitdns, which is mainly dissatisfied with the defects of DNS. The only top-level domain name of namecoin is. Bit. It costs namecoin to register a. Bit domain name
in addition, Q currency, Shanda currency, starting point currency and various online game currencies are also virtual currencies.

a real virtual digital cryptocurrency
the first category is the familiar game currency. In the era of stand-alone games, the protagonist accumulates money by knocking down the enemy, entering the gambling house to win money, and using these to buy Herbs and equipment, but it can only be used in his own game console. At that time, there was no "market" between players. Since the establishment of Internet portal and community, the realization of game networking, virtual currency has a "financial market", players can trade game currency
the second type is the special currency issued by the portal website or instant messaging service provider, which is used to purchase the services in the website. The most widely used is Tencent's q-coin, which can be used to purchase membership, QQ show and other value-added services
the third kind of virtual currency on the Internet, such as Fuyuan currency (FTC), bitcoin (BTC), Wright currency (LTC), etc. bitcoin is an electronic currency proced by open-source P2P software. Some people also translate bitcoin as "bitcoin", which is a kind of network virtual currency. It is mainly used for Internet financial investment, and can also be directly used in daily life as a new currency.
but there is no problem, so it can not be determined
few investors and poor liquidity; Lack of supervision and serious manipulation.
In today's society, e to the high proportion of coal volatilization, the enthusiasm of burning slime in small and medium-sized pulverized coal fired boilers has been improved. Adhering to the new instrialization path, China's rapid economic growth, especially the state's incentive policy for comprehensive utilization of slime. This will bring many difficulties to the coal system of the power plant. According to the calculation, it is necessary to speed up the elimination of backward proction skills, processes, skills and equipment. However, when the moisture content of coal slime is not well controlled, the power sector has caused difficulties in the past e to the entry of coal slime into the coal dryer / lignite dryer system. However, e to the economic benefits, e to the introction of pre crushing, evacuation, dispersion and anti sticking processes in the slime drying process, the plan of coal dryer and lignite dryer is reasonable. Slime is a proct bred in the process of coal mining, and 30% of Slime (weight ratio) can be used when burning medium coal. The application of slime in pulverized coal fired boiler should be carried out actively; Change the cage for birds & quot; According to the strategy, the power plant used slime as fuel to maintain a relatively long-term operation. After manual cutting and drying, it fell behind the coal pulverizing system with intermediate storage bin, but it also paid huge resource and environmental prices. It should be recognized that this has realized the comprehensive utilization of slime, and the utilization of slime can reach 50% (weight ratio) when burning raw coal
practice has proved that the small and medium-sized pulverized coal fired boiler can bring benefits to the enterprise with low energy consumption. The coal dryer and lignite dryer adopt the new technology of crushing and evacuating the slime first, and then thermal drying. Improve the proct awareness
Zhengzhou chemical construction mine equipment factory is a professional manufacturer of high-grade, multi variety, high-quality slime dryer, fly ash dryer, slag dryer, mineral powder dryer, sand dryer, desulfurization gypsum dryer, gypsum dryer, coal dryer, lignite dryer, three cylinder dryer, refractory dryer.

in the selection process of coal dryer and lignite dryer, we need to see the size and cohesiveness of the materials, and choose different forms of board reading. Coal dryer / drying system of lignite dryer includes dryer, combustion furnace, feeder, discharge machine, st removal system, etc
Application of chemical construction coal dryer / lignite dryer: it can dry sticky materials that can not be processed by ordinary rotary dryer. It is a patented proct developed and designed for sticky filter cake materials, which is suitable for drying sticky filter cake materials such as coal slime, washed clean coal, urban sludge, coal slime, choline chloride, red mud, biological waste resie, etc. in large-scale proction
working process of coal dryer / lignite dryer: the slime containing 27-30% moisture is evenly and continuously sent into the coal dryer / lignite dryer through the feeding belt conveyor. The main body of the dryer is a slightly inclined and rotatable cylinder. The hot air generated by the hot blast stove enters the dryer through the connecting pipe, and contacts with the wet coal slime downstream. Coal drying machine / the internal depolymerization mechanism, movable grate wing plate, cleaning device and crushing and dispersing device of lignite drying machine are used to crush the wet coal slime, mix, advance and strengthen heat exchange, and finally dry the wet coal slime into a loose spherical proct with final moisture of 12% - 16% and particle size of about 5-20 mm
features of chemical construction coal dryer / lignite dryer: no material accumulation on the machine wall, high thermal conctivity, fast drying speed, uniform and sufficient drying, good quality, high efficiency and energy saving, etc. Slime dryer | slime drying equipment heat supply system, heat exchange system, ventilation and st removal system organically combine and play its best effect. Among them, the idea of high temperature fast boiling furnace, sectional drying and the collection method of high humidity waste gas st are the first in China. The system of coal dryer and lignite dryer integrates heating, drying and st collection into an organic whole to maximize the drying efficiency of the whole system
According to the definition of the European Central Bank in 2012, "a kind of digital currency that is not legally binding, issued and controlled by developers, and accepted and used in specific virtual community members."
at the 2013 congressional hearing, Federal Reserve Chairman Ben Bernanke said that "in the past two decades, virtual currency has been regarded as an electronic currency, or a payment system technology field that has been developing."< In 2013, the financial crime enforcement network (FinCEN) of the U.S. Department of the Treasury defined it as: "virtual currency is a medium of exchange that operates like real currency in some environments, but it does not have all the attributes of real currency." It also has no legal tender status. In 2014, the European Banking authority defined it as "a digital form of value that is not issued by central banks or government departments and is not necessarily associated with legal tender, but it is accepted by natural and legal persons as a means of payment and can be transferred, stored and traded electronically
in Chinese mainland refers to the currency that runs on the Internet, and the famous virtual currency, such as Tencent Inc's Q coins and the grand company's roll, also has virtual currency in online games. Virtual currency is usually used for users to purchase virtual services on the network, such as QQ membership function of Tencent's QQ coin, online game equipment, etc. Virtual currency is usually a means of payment. For example, the Ministry of culture of the people's Republic of China defined it in 2009 as a virtual exchange tool that is issued by online game operators, directly or indirectly purchased by game users using legal tender in a certain proportion, existing outside game programs, stored in servers provided by online game operators in the form of electromagnetic records, and expressed in specific digital units
