Can meituan use digital currency

1.

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 Finance

The 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

In recent years, a series of policies and measures have been implemented to rece the cost and increase the efficiency of logistics, and remarkable results have been achieved. From 2013 to 2020, the ratio of total social logistics cost to GDP shows a downward trend. From January to September 2020, the ratio of total social logistics cost to GDP in China will drop to 14.4%, which has made a positive contribution to improving the development environment of the real economy and enhancing the operation efficiency of the national economy

however, behind the rapid development of the instry, there are still many problems to be solved, including commodity authenticity, logistics data island (data isolation leads to high interaction cost between enterprises, low efficiency of process collaboration), logistics credit rating (no standard, difficult financing), etc

blockchain technology helps the transformation and upgrading of logistics finance

through blockchain technology, we believe that the pain points of relevant instries can be continuously improved and optimized. For example, it involves commodity traceability, multi-agent collaboration, credit reference, supply chain finance, etc., and integrates "business flow, information flow, capital flow, and logistics". The logistics instry has become an important deployment of the logistics instry

for the future integration development direction, enterprises can combine logistics technology process optimization, logistics package traceability, financial application scenarios based on logistics and supply chain, supply chain and logistics related credit reference needs, rely on blockchain technology and existing logistics network, truly and reliably record and transmit capital flow, logistics and information flow, Optimize the utilization of resources, improve the overall efficiency of the instry, and promote the sustainable development of the logistics instry

through the combination of blockchain and logistics finance application scenarios, in essence, it is through mortgage property and data cross node sharing, and finally, it is to achieve logistics credit rating, so as to obtain financing convenience and interest rate level close to that of large institutions

with the implementation of new digital infrastructure technology represented by 5g, blockchain technology will be combined with AI, Internet of things, cloud computing and other cutting-edge technologies, enabling the construction of economic fields including logistics and other real instries

through the blockchain network, we can change the traditional management and service mode, promote department collaboration and business process optimization, rece communication and information costs, and improve management efficiency. The four major applications in the direction of process optimization, logistics tracking, logistics finance and logistics credit will be graally implemented in the fields of e-commerce logistics, shipping logistics, special logistics and logistics finance

8. In the north of China, e to the difference of wheat maturity time in different places, some people who harvest wheat as a profession in exchange for income. Most of these people are physically strong, skillful, hardworking and willing to work. They are called Mack. The existence of Mack alleviates the difficulties of tight time, heavy tasks and shortage of manpower in the summer harvest season in rural areas. Often because of these problems, it is a good harvest year, but the harvest is not timely, resulting in reced yield and quality. Because of the difference of maturity in wheat procing areas, such as graally maturing from east to west, some of the wheat visitors are located in late maturing areas, from north to south, from south to north, like migratory birds, they migrate and walk all the way, and when the wheat visitors come to their home, their wheat is ripe; The other part is the farmers in the early maturing area who go to the relatively late maturing area to harvest after their own harvest. What they have in common are groups of brothers, father and son, and even husband and wife. They come to the wheat procing areas to find people to hire, cut wheat for others, and exchange sweat for a meager income to make up for the family shortage or find a way out. People in the wheat procing areas call them "Mack.". They usually take a dry grain bag, a scythe and bedding. Maike was recorded at least in the local chronicles of China in the Ming and Qing Dynasties“ In the ten years of the cultural revolution, Mack disappeared. Until the implementation of the household contract system, Mack first appeared in the rural areas of Guanzhong. After the mechanization of agriculture, a large number of harvesters went south and north to harvest wheat every year. Now they are called trans regional machine harvesters. Because they are similar to wheat harvesters, they are also known as wheat harvesters, "modern wheat harvesters", and because they are mechanical harvesters, they are also known as "iron wheat harvesters" and "mechanical wheat harvesters", Therefore, it is now extended to mean that anyone who harvests wheat for others, or even helps others, will become a Mack, just like the word was used at the beginning. The difference between the present and the past: in the past, almost all of the mackerels were forced to leave home to cut wheat for others to make up for their families ring the busy farming season, similar to today's farmers who went out to work. However, the living and working environment was harsh at that time. For example, they had to sleep in the open because they had to sleep in the open. They usually sleep under the eaves of some villages and towns, even in the open air, just like refugees, waiting for their employers, Occasionally, they will stay at the employer's house overnight, because they have to find another employer as soon as they finish their work, and it will be over in half a day. Except because of the large area of harvest or the late afternoon when they come, there is also the catering aspect. Generally, the employer will take care of the meal. Because of the tight summer harvest time and the high intensity of work, the catering employer will be kind to them, but there are also exceptions. If they work after dinner, they will certainly be entertained, If you are a bit stingy after finishing your meal, the employer will be perfunctory. They are still very thrifty after receiving their wages, and they will not use their wages except for having to spend them. Today's wheat harvesters are mechanical harvesters. If the wheat is not harvested in time after maturity, the yield and quality will be reced. At this time of year, the government will give them special care like opening a green channel, such as free bridge toll, high-speed toll, etc. Like the traditional Mack, they also go out together, but in work and life, they are quite different from the traditional Mack. The most remarkable thing is that their tool, the harvester, is operated by many machine owners who employ full-time drivers. They only collect harvest fees, or take turns with their employers or relatives.
