Can digital currency act as a medium of commodity exchange
digital currency is an alternative currency in the form of electronic currency (which can be used for real goods and services transactions)
digital currency has the main characteristics of network packets. This kind of data packet is composed of data code and identification code. The data code is the content we need to transmit, while the identification code indicates where the data packet comes from and goes
based on the characteristics of digital currency, the direct benefit of digital currency to the central bank is not only to save the cost of note issuance, circulation and settlement, but also to enhance the central bank's ability to control funds
Electronic money and virtual money are called digital money. According to the definition of the European Central Bank, virtual money is issued by non central banks, credit institutions and e-money institutions, which can be used as the numerical expression of the value of currency substitutes in some cases{rrrrrrr}

Digital currency is a general term used to describe all forms of electronic currency, whether it is virtual currency or cryptocurrency. It is a form of data expression of value. Through data transaction, it plays the functions of transaction medium, accounting unit and value storage, but it is not the legal currency of any country or region
the concept of digital currency was first put forward in 1983. They only exist in digital or electronic form. Different from the actual paper money or coins, they are invisible. They can only be owned and used on the Internet through e-wallet or designated network. The advantage of digital currency is that there is no bank, the transaction is instant, and the transaction cost is very low. So: coin, token and virtual currency belong to digital currency
the main characteristics of digital currency
1. In terms of payment and settlement, it does not rely on institutions. It is a publicly accessible digital general ledger maintained by the whole distributed network, which is called "blockchain"
2. In terms of issuance and proction, the essence is to keep accounts on a mutually verified public accounting system. Under a certain algorithm mode, find out a string of random codes that meet the conditions, and then package this string of codes with other transaction information into a block and record them in this account book, so as to obtain a certain amount of digital currency
(3) it has no national boundaries, which makes it flow around the world. Virtual world corresponds to the real world, through the exchange relationship between digital currency and traditional currency, under certain conditions, specific digital currency can buy physical goods, and traditional currency can also buy specific virtual goods In theory, its distributed general ledger system can prevent any participant from forging digital currency and rece transaction risk The lower transaction cost of digital currency will promote banks and other financial institutions to improve service level and rece transaction costs Digital currency and mobile financial business model can promote the development of Inclusive FinanceThe role of digital currency:
1. First of all, the central bank's digital currency can provide a huge data base for monetary policy and macro Prudential policy, so that the regulatory authorities can collect real-time trading books of different frequency and different institutions according to their needs, and it is complete and real. This information advantage can help the central bank use policy tools more accurately and flexibly
Secondly, the central bank's digital currency technology can track the flow of funds and help the regulatory authorities to comprehensively monitor and assess financial risks. Finally, the central bank's digital money technology is concive to the transmission of interest rate of monetary policy. Digital currency technology supports "point-to-point" payment and settlement, which can improve the liquidity of market participants. Only the digital currency of the central bank, which is generally accepted by the whole society, can radiate this advantage to the participants of different financial markets, so as to improve the liquidity of financial markets. This will make the term structure of interest rate smoother and the transmission mechanism of interest rate smoother 
extended data:
digital currency can be considered as a virtual currency based on node network and digital encryption algorithm. The core characteristics of digital currency are mainly reflected in three aspects: because it comes from some open algorithms, digital currency has no issuing subject, so no one or institution can control its issuing; Because the number of algorithm solutions is fixed, the total amount of digital currency is fixed, which fundamentally eliminates the possibility of inflation caused by the overuse of virtual currency; Because the transaction process needs the approval of each node in the network, the transaction process of digital currency is safe enough
Digital currency is a double-edged sword. On the one hand, the blockchain technology it relies on has been decentralized and can be used in other fields besides digital currency , which is one of the reasons why bitcoin is popular; On the other hand, if digital currency is widely used by the public as a kind of currency, it will have a huge impact on the effectiveness of monetary policy, financial infrastructure, financial market, financial stability and so on. Specific Wu Xiaoxia:
1. Impact on monetary policy
if digital currency is widely accepted and can play the role of currency, it will weaken the effectiveness of monetary policy and bring difficulties to policy-making
because digital currency issuers are usually unregulated third parties, money is created outside the banking system, and the amount of circulation depends entirely on the wishes of the issuers, which will lead to the instability of money supply. In addition, the authorities are unable to monitor the issuance and circulation of digital currency, which will lead to the inability to accurately judge the economic operation and bring trouble to policy-making, At the same time, it will weaken the effectiveness of policy transmission and implementation
2. Impact on financial infrastructure. 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
3. The impact on financial intermediation and financial market in a broad sense. As a financial intermediary, banks perform the ties of acting supervisors and supervise borrowers on behalf of depositors
generally, 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 mechanisms
4. The impact of security risks and financial stability
assuming that digital currency is recognized by the public, its use increases significantly and replaces legal currency to a certain extent, negative events such as network attacks on user terminals related to digital currency will lead to currency fluctuations, which will have an impact on the financial order and the real economy
in addition, the virtual currency based on blockchain technology is usually held by a few people at the beginning. For example, the first purchase of bitcoin in May 2010 was $25 pizza purchased by 10000 BTC, and the price of each bitcoin rose to $1200 in more than three years by the end of 2013
