1. As early as 2014, the people's Bank of China has set up a special research group to study the central bank's digital currency. Until today, the central bank's digital currency has a real sense of landing. China may become the first economy to issue sovereign digital currency, and 2020 is expected to be the first year of global central bank digital currency
the DCEP issued by the central bank is a digital currency, which is very similar to Alipay and WeChat payment. But it is different from Alipay and WeChat, because it is more like paper money, and the third party can not get the information from both sides of the transaction. It is anonymous and centralization, and the endorsement of the state can be assured.
what is the use of central bank digital currency
from the perspective of the central bank, if the central bank wants to put in funds, it doesn't need these scientific and technological means to trigger conditions, and it could have done it
for users, they have one more option when paying. Users only need to download the central bank's digital currency wallet app, and then associate with their existing bank accounts to exchange the previous banknotes into the corresponding digital currency
for the current mobile payment, users are still accustomed to using Alipay and WeChat to pay. But how to say? Personally, Alipay was originally a professional payment software, but after all these years of development, the Alipay interface is extremely complex, and the user experience is not very friendly.
as for wechat payment, wechat started from social networking at first, and has evolved from professional social software to comprehensive software in recent years. To put it plainly, whether it is Alipay or WeChat, it seems that it has deviated from its original intention. This may bring opportunities to the central bank's digital currency
when will central bank digital currency become popular
according to the bank, considering that the early digital RMB is only limited to the pilot, it will not be issued in large quantities and promoted comprehensively in the short term, and the speed of currency circulation will also maintain a normal level
many people say that digital money has no effect on Alipay. I beg to differ. As Ma Yun said, sometimes it's just a document that beats you. What is the impact of the central bank's digital currency on Alipay? Let's wait and see.

2. The emergence of digital currency was born under the expectation of pursuing a more perfect social and economic transaction mode and Global trade facilitation. It was discovered in the process of using science and technology to graally explore this need. The history of digital currency should start with the creation of bitcoin
the creation of digital currency
the origin of digital currency can be traced back to the 1990s, and electronic gold is one of the best forms. E-gold came out in 1999. It is based on real precious metals. Another consistent digital currency service is LR. Founded in 2006, it is an online payment company in Central America. It allows users to convert U.S. dollars or euros into LR, and only 1% of the transaction cost can be exchanged freely. This kind of two-way service is used by some people to launder money, so it is inevitably shut down by the U.S. government under the charge of money laundering
then, a person named Nakamoto published an article called "bitcoin: a peer-to-peer e-cash system" in the cryptography forum, which gave birth to bitcoin. Compared with legal currency, bitcoin does not have a centralized discoverer, but is generated by the calculation of network nodes, and is composed of a series of complex codes generated by computers. Anyone can dig, buy and sell bitcoin, and it is an anonymous transaction and cannot be tampered with. As a result, it is surrounded by geeks of popular technology, pursuers of complete liberalism and speculators
digital currency can be divided into open mining cryptocurrency and issuing cryptocurrency. Digital currency is defined as an Internet-based currency or exchange medium, which is different from physical currency. Digital currency can realize instantaneous transaction and ownership transfer without borders
for reference.

3. There is no established timetable for digital currency
Zhou Xiaochuan pointed out that as legal tender, digital currency must be issued by the central bank. The issue, circulation and transaction of digital currency should follow the idea of integration of traditional currency and digital currency, and implement the same principle of management. That is to say, q-coin and the like are definitely not good
as for whether to use blockchain technology to create digital currency. Zhou Xiaochuan said that the blockchain technology is an optional technology, but so far, the blockchain still occupies too many resources. Whether it is computing resources or storage resources, it can't cope with the current transaction scale, and whether it can be solved in the future depends on it. Zhou Xiaochuan said that in addition to blockchain technology, the digital currency research team of the people's Bank of China has also concted in-depth research on other related technologies involved in digital currency, such as mobile payment, trusted and controllable cloud computing, cryptographic algorithm, security chip, etc
in addition, Zhou Xiaochuan also mentioned that there is a lot of discussion about "51% attack" (assuming that indivials have 51% of the computing speed of the whole network, they can realize double payment, reverse transactions, paralyze the whole network, and completely lose the transfer function). More specifically, compared with the special currency, bitcoin does not need the central bank. Zhou Xiaochuan mentioned that for the digital currency controlled by the central bank, a series of technical means, mechanism design and laws and regulations will be adopted to ensure the security of the digital currency operation system, which is different from the design idea of bitcoin from the beginning
as for the digital currency timetable, Zhou Xiaochuan said that there is no established timetable. The relationship between digital currency and cash will be parallel and graally replaced for quite a long time. For reference.

4. The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
unlike all currencies, bitcoin does not rely on a specific currency institution to issue. It is generated by a large number of calculations based on a specific algorithm. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
on December 17, 2017, bitcoin reached an all-time high of $19850.

Crystal has an ornamental effect
crystal ornamental stone is the most representative work of natural crystal, which has the ornamental value that other gemstones do not have. Whether it's jade or jadeite, it needs to be carved to reflect its value. Crystal ornamental stone only needs to polish the surface, that is, to show the material wrapped in the crystal, and directly appreciate the original crystal
naturalness is the basic characteristic of crystal ornamental stone. Generally, the integral crystal mineral has high ornamental value without decoration, but the inclusion crystal ornamental stone often needs to be polished properly, which is more convenient to appreciate the inclusions in the crystal
crystal ornamental stones are often very strange in shape, texture and internal characteristics. Nature has infinite scenery, which can be found in the miniature of inclusion crystal

skills of identifying crystal:
1. Temperature
holding the crystal in your hand for a period of time, natural crystal feels cool, while glass jewelry is generally warm, and it may be unnatural crystal that changes temperature rapidly in your hand
Second, the price of natural crystal is more expensive than that of synthetic crystal. It is said that good procts are not cheap. Therefore, when we face the crystal whose price is too low than the market price, we should pay more attention The hardness of natural crystal is 7, while the glass is only 5. As long as the hardness is greater than 5, the glass can be scratched. Therefore, a simple test can be carried out on the glass to see if there are scratches In terms of color, just pay attention to green crystal. There are few green natural crystals, so most green crystals on the market may be synthetic The crystal with inclusions is generally not fake, because it costs a lot to forge such a thing, which not only takes a lot of effort, but also makes the effect easy to see through7. In 2016, the central bank did not issue digital currency, but in 2016, the central bank led a digital currency seminar in Beijing. The relevant person in charge of the central bank said that digital currency should be launched as soon as possible. But later, Zhou Xiaochuan, the Central Bank of Hangzhou, said that the time for issuing digital currency is not ripe, and it may take ten years. Moreover, the design concept of the digital currency to be issued by the central bank is different from that of the digital cryptocurrency such as bitcoin, Ruitai coin and Laite coin, which is not a decentralized digital currency.
