Shopping with digital currency
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 integrated network card of computer platform has been popularized for 1000m many years ago. If you take any antique computer and look at the parameter label of integrated graphics card, it will be network card 10 / 100 / 1000m, which is no longer the bottleneck and far exceeds the upper limit of broadband access. The wireless network card of this model of notebook also supports 5g WiFi, which can run over 1000m in 2x2. At present, only 200m to 500m is popularized in most areas, which is also the hardware far ultra access broadband. The only thing you need to consider is whether your router is OK. If you only rely on WiFi to use your computer, you should buy a slightly better router of about 200 or more. Of course, you can buy a cheap miner like 360p4g. But if you don't consider this type of proct, you should only consider the new mainstream retail model, As mentioned above, 200 + routers have more rendant performance
Official Journal;
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
