Three advantages of virtual currency
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

In the future, there will be data for medical treatment or health planning, and the real master of this data is the patient himself, not the hospital or a third-party organization. In addition, these data have strong privacy, and the use of blockchain technology also helps to protect the privacy of patients
payment system
compared with the existing traditional payment system, blockchain technology can avoid the complex system, directly between the two sides of the transaction, does not involve intermediary institutions, even if part of the network is paralyzed, it will not affect the operation of the whole system. This method has the characteristics of low price, fast speed, and no intermediate fees
banking
as a digital, secure and anti-interference account, blockchain realizes the core function of Banking: the safe storage and transfer center of value. Some banks with keen sense of smell in the world have begun to actively plan to join the army of blockchain research and application in order to gain the initiative in the fierce competition in the future
identity authentication of blockchain
blockchain has the feature of being accessible to everyone. Everyone can query the block information in any place with network. The high transparency also makes blockchain full of charm. In the future, ID card and account book are basically not needed, because every identity information can be written into the blockchain.

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 P>
