1. 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.

2. For many people, the concept of digital currency is a mystery. But there is no doubt that digital currency is different from virtual currency
virtual currency is the electronization of illegal currency, and its original issuer is not the central bank. This kind of virtual currency is mainly limited to circulation in a specific virtual environment. Digital currency can be used for real goods and services transactions, but only the digital currency issued by the state is legal digital currency
in 2013, the central bank, together with five ministries and commissions, issued the notice on preventing the risk of bitcoin, which clearly defined non legal digital currencies such as bitcoin as virtual commodities, not in the form of currency and legal currency< At the same time, digital currency is different from electronic payment. In the actual use experience, digital money and electronic payment may feel similar, but they are still quite different in essence. Before digital currency, the financial instry has been highly informationized. Such as Internet banking, WeChat, Alipay and so on pay the popularization of electronic technology, physical cash accounts for only a very small part of the total circulation of money. In spite of this, because the money used in the transaction comes from the bank account, it actually corresponds to the banknotes.

3. Digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English. It is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
digital currency is an unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of a specific virtual community. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form

4.
Digital currency is a kind of legal tender, which must be issued by the central bank. Both digital gold coin and cryptocurrency belong to digital currency, which is not a network virtual currency, because it is not limited to virtual space, but is often used for real goods and services transactions, such as bitcoin, Wright coin, bitstock, etc. at present, there are thousands of digital currencies issued around the world
extended data:
1. Impact on financial infrastructure
the decentralized mechanism of value exchange based on distributed ledger technology has changed the basic settings of gross and net settlement on which financial market infrastructure depends. The use of distributed ledgers also poses challenges to trading, clearing and settlement, as it promotes the disintermediation of traditional service providers in different markets and infrastructures. These changes may have potential impacts on market infrastructure other than retail payment systems, such as large payment systems, securities settlement systems or trading databases
If digital currency and distributed ledger based technology are widely used, it will bring challenges to the intermediary role of financial system participants, especially banks. As a financial intermediary, banks perform the ties of acting supervisors and supervise borrowers on behalf of depositors. Usually, banks also carry out liquidity and maturity conversion business to realize the financing from depositors to borrowers. If digital currency and distributed ledger are widely used, any subsequent disintermediation may have an impact on savings or credit evaluation mechanisms5.
Generally, the excellent digital currencies are mostly imported procts, such as bitcoin, Leyte coin, ether coin and so on. However, the domestic Yuanbao coin, Ruitai coin, bitcoin and the tokens of different crowdfunding projects of European crowdfunding are excellent digital currencies
digital currency (English: digital currency) is an alternative currency in the form of electronic currency. At present, no central bank of any government has indicated that it will issue digital currency, and digital currency does not have to have a benchmark currency and a central bank
it is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography
6. You have said that digital currency and RMB are 1:1 equal use, then 10 million digital currency, of course, can be converted into 10 million RMB
7. Digital currency is played in app. It's simple.
8. It is reported that the central bank's research on the issue of digital currency is not a temporary move. Since 2014, the research on the central bank's digital currency has been carried out for five years. In 2017, the digital currency Research Institute of the people's Bank of China was officially established, and has applied for more than 70 patents related to digital currency technology< In recent years, with the development of Internet technology, especially blockchain technology, many so-called "virtual currencies" have emerged in the world, such as bitcoin and Laite currency, which are controversial in recent years. So, how is the digital currency proposed by the central bank different from these commercial "virtual currencies"? The following is an analysis of the patent of Xiaoju
