What is digital currency dcny
there are two main reasons why user experience optimization is listed separately. First, LBTC wants to build an excellent peer-to-peer e-cash system. Its basic idea is to put payment experience and user first, so it puts it at a high level, such as cross platform light wallet, accelerating payment confirmation speed, optimizing irreversible block mechanism, etc. Second, LBTC has always emphasized superior chain governance system. Before that, there was a standardized SGS (spark governance system) governance system, but it still needs to constantly improve the relevant mechanisms. For example, we should greatly optimize the node parameters and election mechanism, establish the LBTC foundation, multi-channel proposal process, and light wallet's support for the governance function on the chain.

e-rmb means that there is a virtual wallet on the mobile phone, and your cash will appear in the form of pictures in your virtual wallet
electronic RMB advantages:
1, no Internet payment. Although Alipay and WeChat payments are widely used nowadays, payment will fail if there is no network or network signal difference. The central bank has launched the "touch and touch" function, which can pay whether there is network or not
2, farewell bank cards, Alipay and WeChat payment need to bind bank cards, and they serve as a medium to make payment easier. However, e-rmb has bid farewell to the bank card and has only one unified E-wallet
3. It is concive to cracking down on cash crimes, and finding criminals by searching the flow direction of RMB through electronic RMB. Once the traditional currency is traded or laundered, it will be difficult for the country to find clues, while electronic RMB will not have this disadvantage. At the same time, e-rmb also reces the cost of national banknote printing

crown number - Introction
in addition to Chinese characters, minority characters, Chinese pinyin and Braille on the fourth set of RMB notes, there are also crown numbers and numbers used to control the printing quantity of various tickets and to prevent counterfeiting. Crown is also called "prefix", which is the symbol printed in front of the ticket number to indicate various tickets and the batch number of printed quantity. In the history of China, when banks printed banknotes, they used different crowns. One or two English letters (a, B, C, D, etc.) were used as the prefix for the guanjin voucher, Jinyuan voucher and the Northeast nine province circulation voucher printed by the Central Bank of old China; One or two Arabic numerals (1, 2, 3, 4, etc.) were used as the prefix of the counterfeit coins printed by the Central Bank of Manchuria and the Bank of Inner Mongolia ring the period of Japanese invasion of China. Among the five sets of RMB banknotes issued by the people's Bank of China, the first three sets all use two or three different Roman numerals (I, II, III, IV, etc.) as the prefix, while the fourth set of RMB uses two identical or different Chinese Pinyin letters as the prefix, The circulation Commemorative Banknote "Celebrating the 50th anniversary of the founding of the people's Republic of China" only uses a Chinese pinyin letter J as the prefix (with a small number of I prefix complements). The number is also the number indicating the number of tickets printed. It is the specific number in each crown word batch number. Generally, the number is arranged in Arabic numerals, one ticket for each ticket. Generally, the number in the same crown word batch number will not be repeated. From the number of banknotes, we can see the number of banknotes printed by this group of words. That is to say, the more the number of banknotes, the larger the number of banknotes printed. On the contrary, the less the number of banknotes printed. From each set of RMB tickets, there are six, seven and eight RMB numbers
prefix number - definition
the "prefix" on RMB banknotes is the two or three letters printed on the banknotes to mark the printing batch, which is arranged and printed by the banknote printing factory according to certain rules“ "Number" refers to the Arabic numeral serial number printed on the back of the prefix, which is used to indicate the order of each banknote in the batch with the same prefix.
there are many kinds of crowns on banknotes in various countries, such as local characters, letters, Roman numerals, etc. The first, second and third sets of RMB in China use Roman numerals, while the fourth and fifth sets use Chinese pinyin. The number of RMB notes is usually composed of two parts: the crown character and the serial number. The crown character actually plays the role of the batch number, and the serial number is the quantity in the batch number
RMB is the identity card of the renminbi. As with the ID number of each person, the number of RMB has certain regularity and significance, so that every renminbi will have traces. This is not only a series of numbers, but also a verification of the identity of RMB, and a unique symbol. Not only that, it can also be said that it is an anti-counterfeiting sign, so the number of RMB has a very wide range of significance
Third, the collection value of different titles< p> When collecting RMB, the most important thing for RMB collectors is to look at the Guanzi brand. However, because of its large number of issues and scattered distribution, it brings great challenges to the collection. But it is precisely because of this challenge, for professional collectors, that the collection value of RMB is much higher than the actual value of RMB. However, for the public, RMB is only a proct of equivalent exchange, and its essence is the medium of exchange. We must not exaggerate the collection value of RMB. After all, every RMB is unique like everyoneU.S. dollar is the legal tender of the United States of America. The US dollar banknotes in circulation at present are all kinds of banknotes issued since 1929
In 1792, the coinage act of the United States was passed. The current issue of dollars is controlled by the Federal Reserve. Since 1913, the United States has established the Federal Reserve System and issued Federal Reserve bonds. More than 99% of the banknotes in circulation are Federal Reserve notesthe issuing department of US dollars is Congress, and the specific issuing business is handled by the Federal Reserve Bank. After World War II, Continental European countries and the United States reached an agreement to use the U.S. dollar for international payments. Since then, the U.S. dollar has been widely used as a reserve currency in countries other than the United States and eventually become an international currency
extended data:

generally speaking, the dollar and gold are negatively correlated for most of the year, that is, when the dollar falls, gold is on the rise, while when the gold falls, the dollar is often on the rise
Serial number RMB refers to the number of multiple personal name currencies, and the number increases continuously
for example, the numbers of the three coins are d38l839980, d38l839981 and d38l839982
because each RMB number is unique, serial RMB has high collection value

notes for serial RMB collection:
1. The first thing to ensure is the "appearance" of banknotes. For a long time, many collectors think that I have such a coin in my hand, which is collectable and of very high value. There may be some misleading reasons, There are also factors that we do not understand about the market transactions
2. Pay close attention to the "bill gall" in the collection of banknotes. The so-called "bill gall" refers to the relatively high value banknotes, such as the "Twelve treasures" in the first set of RMB, the "Su San coin" in the second set of RMB, the "five Golden Flowers" in the third set of RMB, and the "80 version" in the fourth set of RMB, The collection value of "ticket gall" is more obvious
3. When you collect them, try to fill them as many as possible. It's not just that the number of them is enough, but that the number of these banknotes is continuous, and they are all serial numbers. Generally, such "100 pieces" are wrapped with wrapping paper and special packing instruction paper of the people's Bank of China
