Digital currency under internal test
The digital currency of the central bank is DCEP
the name of the digital currency developed by the central bank is DCEP (digital currency electronic payment). DC is digital currency. EP is electronic payment. Payment transmits digital things through a certain way, not paper currency. Therefore, electronic payment itself has the attribute of digital currency
The characteristics of digital currency are: low transaction cost; Fast trading speed; Highly anonymous

Application of digital currency
I. fast, economic and safe payment and settlement
cross border payment helps RMB internationalization. In 2015, the settlement volume of cross-border payment involving current account is about 8 trillion yuan. To accelerate the internationalization of RMB, cross-border payment and settlement procts and solutions with low cost, high efficiency and low risk are needed
At present, there are still a lot of repetitive human work in the bank's electronic loan process and processing process, and as the basic support of loan issuance, many of the collateral has the situation of false pricing or multiple or even no collateral. We can consider using digital currency to price and track bank collateral:3. Bill finance and supply chain finance
in recent years, various bill market businesses based on commercial bills have grown rapidly, and bill financing procts have become a hot area of Internet financing. However, about 70% of the current bill businesses in China are still paper transactions, Supply chain finance is also highly dependent on labor costs

Hello, where are the first batch of pilot cities of the central bank's digital currency? Do you think they are well deserved super first tier cities "Beijing, Shanghai, Guangzhou and Shenzhen"? I want to tell you that it's not all right. Except Shenzhen, the other three cities are Cheng, Suzhou and xiong'an new area. At present, Shenzhen is the earliest city to launch digital currency. On October 9, Shenzhen issued 10 million digital currency. 50000 people, 200 yuan per person, can enjoy the welfare, which is distributed to everyone free of charge through the way of wagging number. Here, I can only envy you. The implementation of digital currency is so fast. The friends in the pilot cities are lucky. I just want to watch you win the lottery
the first batch of pilot cities are selected in these four cities, which is the first step for digital currency to go to the whole country. When it matures in the future, it will be promoted to more pilot cities. So don't worry, just wait. Even if our city is not a pilot, it doesn't matter. Next time it will be our city. The pilot is just to test the stability of the system, and we don't have a great chance to get the red envelope of digital currency. There are so many people in Shenzhen, and only 50000 numbers are selected. Here we would like to express our support and thanks to the cities selected as the pilot cities of digital currency
so, what's the significance of this digital currency? Why do you have to work hard to do this? For most people, it really won't have any impact, but for a small number of people, it will have a great impact. This small group of people are those who engage in illegal activities
for example, if some people are corrupt and accept bribes, they specify that they can't let others put money on the bank card. That means they are directly arrested, but they can't be found with cash. If we restrict the large amount of cash consumption in the future, for example, if you have to spend more than 5000 at one time, you can't use cash, you need to use digital currency. In this way, those who have bribed tens of millions of cash in their families may not want to spend all their money in their lifetime. And their illegal income doesn't go to the society. It's just paper. They still occupy space at home. Once they start to spend money in digital currency, it's easy to find out. That is to say, all our income will be counted. Once they are involved in crimes, it's easy to be caught. At that time, there will be less Telecom fraud, This is the meaning of digital currency
It is not currently available
at present, the Central Bank of China has not issued and approved the digital currency of issuers and investors
However, at the beginning of the year, the central bank held a seminar on digital currency, at which it made it clear that it was necessary to issue digital currency as soon as possible, and the central bank put the issue of digital currency on the agendahowever, so far, the central bank has not issued any digital currency, and Zhou Xiaochuan, the governor of the central bank, said that the time is not ripe to issue digital currency. Moreover, the digital currency issued by the central bank is different from bitcoin, Ruitai, Laite and other digital cryptocurrencies, and the digital currency issued by the central bank is not decentralized
when the central bank issues digital currency, it needs to establish a basic digital currency system. In this system, the central bank is in charge of the digital currency issuing bank, the commercial bank is in charge of the bank, and the public and indivials hold digital wallets. This is not much different from the existing monetary system in essence, but the managed currency is changed from paper money to digital cryptocurrency
in terms of issuing mechanism, there are two modes:
one is the traditional mode of "central bank commercial bank", that is, the central bank issues digital currency from the issuing bank of the central bank to the Bank of the commercial bank. When an indivial withdraws money from the commercial bank, the digital currency is transferred from the commercial bank to the personal digital wallet
another mode is the "central bank public" mode, that is, the central bank can directly issue digital currency from the currency issuing bank to the digital wallet of the public and indivials. In essence, no matter which issuing mode, money is ultimately held by the public, which is the debt of the central bank to the public
coinbase transaction is a special transaction that generates bitcoin "out of thin air". Only miners can write this kind of transaction, and the number of generated bitcoin is limited by rules (new currency reced by half for every 210000 blocks + transaction fee for this block)
however, the rules do not stipulate that the miner must take away all the rewards that can be taken, and can choose not to take them
therefore, a mine pool connected with the RSK side chain has made a bug before, forgetting to take away the reward and occupying a pit in a block for nothing, which is equivalent to destroying the corresponding amount of bitcoin, making the total amount of bitcoin decrease a little bit permanently
in addition, to spend a bitcoin, you only need to specify the transaction ID and output serial number
as like as two peas in multiple blocks repeatedly write identical coinbase transactions, the transaction ID is also repeated.
therefore, this kind of situation also occupies the pit of a block in vain, and permanently destroys the corresponding amount of bitcoin
it seems to me that this is still a security vulnerability, so the new version of bitcoin software later banned the writing of repeated coinbase transactions. But until now, there has been no ban on miners not getting their e rewards
generally speaking, a coin is controlled by a private key. If a coin is transferred to an address where no one knows the private key, it will be destroyed
if the owner does a good job in security, and the private key is not disclosed and cannot be guessed, but he accidentally loses the private key, it is equivalent to destroying all the coins he owns
there are only some special circumstances that require intentional destruction of coins
one is irreversibly converted into another kind of currency, such as the contract currency XCP attached to bitcoin and wormhole cash WHC attached to BCH
the second is to save certificates and data on the chain, such as the time stamp: panbiao.com/2013/08 /
and the crowd funding of the original Ethereum founding team: zhuanlan.hu.com/p/29
the private key is essentially a big number. Whoever knows this number can control the currency on the corresponding address. So the private key must be generated with reliable random number, otherwise it may be guessed and stolen
compared with the token, the address is the hash of the public key. There is no way to judge whether an address has a corresponding public key and private key (even if the public key is known, the corresponding private key cannot be known). Therefore, even if it is explicitly the address of "burned" token, the system does not prohibit the transfer in
strictly speaking, what locks the currency is a small program (script). This program takes the input as the public key and digital signature. First, check whether the public key hash is consistent, and then check whether the digital signature is valid. If it is valid, it will be verified and transfer is allowed; Otherwise, it will be judged that the transaction is illegal and refuse to package into the chain
it is the whole node software that explains and executes this program. It can be said that the software code of the whole node specifically defines a coin
however, the current situation is very embarrassing. Most miners do not run the whole node, only a few mines are running. The vast majority of users do not run the whole node, even if they run the whole node, they can only perform verification, no computing power, no block.
Look at the memory, the server
in the past, I had a Diablo mod version, but it changed the settings of hackmap after installation. At that time, ETH equipment became scarlet letter, and weather effects still existed after hackmap was turned on, which made me angry. It was useless to reload hackmap. Finally, I reloaded the Diablo, which made me angry when I thought about it~~~~
what we are doing now with Hong Kong is just routine technical testing. When the time is ripe, digital currency can be applied in the scenario of cross-border payment now digital goods are developing faster and faster, and each country is developing its own digital currency. In the case of existing technology, digital currency at the national level certainly has no technical obstacles
in order to promote the application of digital currency, countries are also trying to carry out various tests. On the technical level, digital currency has no barriers, but cross-border projects are not just technical. Digital currency has a long way to go{ RRRRR}
Third, digital currency is far away from internationalizationdigital currency is now in the pilot stage of a few cities in China. But the promotion of domestic application scenarios also takes time. Although there are no technical barriers for digital currency, after all, digital currency involves a wide range of aspects, and the promotion of digital currency can not be completed overnight
now when digital currency is promoted in China, it is easy to carry out cross-border projects after accumulating enough experience and waiting for the right time

first, after China, Thailand will also test the digital currency of retail central bank next year
On April 2, an assistant president of Thailand said that the Bank of Thailand will start testing retail central bank digital currency in the second quarter of next year, and then it will be fully implemented in the next three to five years, Reuters reported. Vachira arromdee, vice president of Bank of Thailand (BOT), pointed out at a briefing that retail CBDC aims to provide convenient and safe financial services. She also said: & lt; This will not affect Thailand's financial system. Vachira arromdee pointed out that the Bank of Thailand will seek public opinions before June to develop this type of digital currency < / blockquote >
four, digital currency can monitor the context of all money
all my friends are saying that China wants to control the digital currency. Now they are desperately exchanging money for fear that it will be difficult to take money abroad in the future
also, digital currency can control the whereabouts of , for example, you can't transfer your meal money to the car selling account. I don't need to say the effect. But now we seldom use paper money, all of which are transferred with WeChat Alipay, all numbers. p>
digital currency relies too much on mobile phones, and its disadvantages are unpredictable. People's lives are always changing, which makes people feel turbulent and uneasy
we need to generate currency consensus through digital currency test
before talking about digital RMB, let's talk about the essence of currency. Currency itself has no value, but the national credit endorsement behind it is the use value of currency itself. The recently launched digital RMB is also a policy to promote the internationalization of RMB. At present, the currency in circulation in the world is settled in US dollars, because the United States, through its own military repression, requires the global oil trade to be settled in US dollars. As a result, 70% of the global trade is settled in US dollars. In order to break this settlement method, the use of digital RMB can rece the exchange rate settlement problem between countries, which is why the introction of digital RMB
the central bank's digital currency has opened a new round of pilot. As a test and promotion area of digital RMB, Hong Kong tests it in strict accordance with the rules for the use of digital RMB. This time, the digital RMB is supported by the state, and fully promotes the reform of the financial digital era. The digital circulation and revolution of currency issuance is quietly going on. I hope that the digital currency of the Central Bank of China can seize the opportunity in this revolution and let the people enjoy the dividend in the future digital currency
