1、 Different definitions:

1. virtual currency:

virtual currency refers to non real currency

digital currency:

digital currency is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy

3. Cryptocurrency:

cryptocurrency is a kind of transaction medium that uses cryptography principles to ensure transaction security and control the creation of transaction units

4. Token (token):

a kind of article whose shape and size are similar to currency, but the scope of use is limited and has no currency effect, and its token is the homonym of token in English

Second, the characteristics are different:

1; It can also be said that virtual currency is personalized currency. In another way, it can also be called information currency

2. Digital currency:

is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities

4. Token (token):

usually needs to be exchanged for money, used in shops, playgrounds, mass transportation and other places, as a voucher to use services and exchange goods

extended data

at present, digital currency is more like an investment proct, because it lacks a strong guarantee agency to maintain its price stability, and its role as a value measure has not yet appeared, so it can not be used as a means of payment. As an investment proct, digital currency cannot develop without trading platform, operating company and investment company

digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields except digital currency, which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market and financial stability

2. In addition to bitcoin, there are many other virtual currencies in the virtual world< Liteoin (LTC) was released on October 7, 2011, and is currently the most valuable counterfeit currency, accounting for about 2% of BTC's market value. The current unit price is US $2.31, with a total currency value of US $38 million

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.

3. Virtual currency refers to non real currency. Well known virtual currencies, such as online currency of Internet company, q-coin of Tencent company, q-point and voucher of Shanda company, micro currency launched by Sina (used for micro games, Sina reading, etc.), chivalrous Yuanbao (used for chivalrous road game), silver grain (used for bixue Qingtian game), and popular digital currencies in 2013 include bitcoin, Laite coin, infinite coin, quark coin, zeta coin, etc Barbecue coins, pennies (Internet), invisible gold bars, red coins, prime coins. At present, hundreds of digital currencies are issued all over the world. Popular in the circle & quot; The legend of "bitcoin, Wright silver, infinite copper, pennies aluminum"
according to the notice and announcement issued by the people's Bank of China and other departments, virtual currency is not issued by the monetary authority, does not have legal compensation and mandatory monetary attributes, is not a real currency, does not have the same legal status as currency, cannot and should not be used as currency in the market, and citizens' investment and transaction of virtual currency are not protected by law

EOS: EOS can be understood as enterprise operation system, which is a blockchain operating system designed for commercial distributed applications. EOS is a new blockchain architecture introced by EOS software, which aims to realize the performance expansion of distributed applications. Note that it is not a currency like bitcoin and Ethereum, but a token based on the EOS software project, known as blockchain 3.0

The main features of

EOS are as follows:

1. EOS is a bit similar to Microsoft's windows platform. By creating a developer friendly underlying platform of blockchain, it supports multiple applications to run at the same time and provides the underlying template for the development of DAPP

EOS solves the problems of delay and data throughput by means of parallel chain and dpos. EOS can process thousands of data per second, while bitcoin has about 7 transactions per second, and Ethereum has 30-40 transactions per second

There is no service charge for EOS, and the general audience is more extensive. The network and computing resources needed to develop DAPP on EOS are allocated according to the proportion of EOS owned by developers. When you have EOS, it is equivalent to having computer resources. With the development of DAPP, you can lease your EOS to others. From this point alone, EOS has a wide range of value. To put it simply, if you have an EOS, it is equivalent to having a set of rent to collect rent for others, or having a piece of land to rent for others to build a house. Digital currency exchange "currency exchange"

development prospects

through a more in-depth understanding of EOS, EOS is quite valuable for investment. First of all, as the first to launch smart contracts, ETH runs smart contracts on eth, which is not free and depends on your gas. If gas runs out, the contract will stop. According to people who have used eth trading platform, it runs slowly and is very expensive, However, there is no such problem in EOS. The operation contract on EOS depends on the number of EOS you have. The more EOS you have, the more you can rent. With the continuous development, the more expensive the price will be; Secondly, it's very simple to develop DAPP on EOS, and you don't need to write many moles, because EOS itself builds the bottom mole for developers, which provides a platform and greatly reces the threshold of development; Thirdly, as an ordinary investor, owning EOS is equivalent to owning real estate, which can be used to rent and earn money. With the development of DAPP, the number of users increases, and the price increases irresistibly

5. The virtual currency in 2k19 is actually the VC currency in the game. Among many options that need to be purchased, this kind of currency is generally consumed. It can be consumed when adding points for self created players, and it can also be used to purchase cards and bags.

8. The ship unloader is a major loading and unloading equipment at the front of the wharf, which plays an important role in the efficiency of the system. Therefore, each major port is based on the largest ship type docked at the wharf. In order to achieve the maximum proctivity of the system, efficient and reliable ship unloaders are selected. At present, grab ship unloaders are mostly used in coal and ore terminals in China
the bridge type grab ship unloader is composed of lifting mechanism / opening and closing mechanism, trolley traction mechanism, pitching mechanism, cart traveling mechanism, blanking and recycling device, boom hook and metal structure, electrical and control system equipment, etc. During the operation, the grab grabs the materials from the cabin and lifts them to the top of the hopper for discharging. The materials are sent to the belt conveyor system of the wharf below by the vibrating feeder
the bridge type grab ship unloader needs three main working mechanisms to complete a grab working cycle, namely the grab lifting / lowering mechanism, the grab closing / opening mechanism and the trolley traveling mechanism. The core part of bridge type ship unloader is the traveling mechanism of grab car. After decades of development, grab car has experienced the development of self-propelled car, wire rope traction car, and in recent years, it has developed to four drum single car traction.

2000. For convenience, K is usually used to represent the unit of 1000, and 2K means 2000 RMB. 2K can also represent some other currencies or game virtual currencies, so you should see clearly that the table does not indicate RMB. In the same way, 2W means RMB 20000

Introction:

the unit of RMB is yuan, and the subsidiary units of RMB are Jiao and Fen. One yuan is ten Jiao, and one Jiao is ten Fen. Since the issuance of RMB, the people's Republic of China has lasted for more than 60 years. With the development of economic construction and the needs of people's life, it has graally improved and improved. So far, it has issued five sets of RMB, forming a multi variety and multi series monetary system of paper currency and metal currency, ordinary commemorative currency and precious metal commemorative currency. Except for 1, 2 and 5 cents coins, the first set, the second set and the third set of RMB have been withdrawn from circulation, and the fourth set of RMB has been withdrawn from circulation since May 1, 2018 (except 10 cents and 50 cents notes and 50 cents and 1 yuan coins)

< H2 > extended information:

China's anti-counterfeiting technology has been at the world's top level

in recent years, China Banknote Printing and mint Corporation has been constantly pursuing and studying the world's advanced anti-counterfeiting technology, and constantly improving the anti-counterfeiting technology level of RMB. In addition to the traditional anti-counterfeiting technologies such as watermark, security line and intaglio engraving, the 2005 version of RMB also adopts more new public anti-counterfeiting technologies. At the same time, it draws lessons from the design concept of foreign banknotes, and fully applies the anti-counterfeiting technology in the machine reading function of banknotes, greatly enhancing the anti-counterfeiting technology of the fifth set of people's banknotes

"at present, China's anti-counterfeiting technology is at the top level in the world," He Lin said. "So far, we have not found that a counterfeit banknote is a" gravure printing "or" papermaking watermark ", and the watermarks of counterfeit banknotes are all post printed. It is almost impossible for imitators to achieve "high simulation."
