Gold paper money virtual currency over thousands of years

1.

Gold was discovered in prehistory. From the 6th century to the 1st century, gold began to be used as currency

Relevant introction:

gold has been recognized and highly valued in prehistoric times. It may be the earliest metal used by human beings, used for decoration and rituals. As early as 2600 years ago, Egyptian hieroglyphs have been described in gold

The earliest known place to use gold as currency was Lydia, who made coins in the form of silver and gold alloys 700 years ago. In China ring the 6th or 5th century, a kind of gold coin called Ying yuan was circulated in the state of Chu

extended data

the technology of gold mining from the first century to the second century was improved at this time. The ancient Romans developed a new method of large-scale gold mining using hydraulic mining, especially in the Iberian Peninsula in the first 25 years and in the provinces of Dacia in the first 150 years

at that time, the main use of gold was to make jewelry, and the use of gold coins was more common than that in Greece. The theme of jewelry mainly changes from depicting mythology to more ordinary geometric patterns

in the early days of the Eastern Roman Empire, pure gold jewelry began to add the element of gem. Its main theme is to praise the power of the church and the king. At this time, gold processing technology reached a peak

2. Currency
is the proct of the development of commodity exchange. For example, in primitive society, if there were no surplus procts, there would be no commodity exchange and no currency. Later, the surplus value graally appeared, there was commodity exchange, and it graally developed into a general equivalent (such as shells in the early days, and then metals), and the general representative of all commodity values, namely currency, appeared

paper money
is developed after the collapse of the metal currency system. It belongs to the credit currency, which is independent of the form of money and serves as the medium for the exchange of goods and services

international currency
for this, there is no clear concept, but it can be regarded as performing the function of general equivalent in the international market, which is recognized by the international central bank

Gold
to be exact, it is full value currency, that is, it is currency when it performs monetary function, and it can also be sold as a commodity, and its value is equal when it is used for two purposes. It was an early currency

RMB (as China's standard currency)
is both paper money and currency!

From the phenomenon of paper money, at present, all countries in the world do not use gold coins, and paper money can not be exchanged for gold. The legal gold content of paper money is meaningless. It seems that there is no connection between paper money and gold. However, the phenomenon of things can not fully reflect its essence, and sometimes even distort its essence

1. Similarities

the essence of money is general equivalent, which can be exchanged with all commodities; Paper money is a compulsory currency symbol issued by the state. It is the proct of the development of money as a means of circulation. Paper money can replace money to perform the functions of means of circulation and means of payment

the common ground of currency and paper money can be summarized as follows: they are both the media of commodity exchange, and have the functions of means of circulation and means of payment

2. Differences

the essential difference between them is that money is a commodity and has value, while paper money is just a currency symbol, not a commodity and has no value

because paper money is not a commodity and has no value in itself, it can not replace money to perform the function of value measure and storage means, and it can not completely act as the function of world currency

According to different user needs and scenario applications, blockchains are divided into three categories: public blockchain, private blockchain and consortium blockchain

the degree of decentralization of public chain. This kind of public blockchain, represented by bitcoin and Ethereum, is not controlled by a third party. All people in the world can read the data records on the chain, participate in transactions and compete for the bookkeeping rights of new blocks

program developers have no right to interfere with users, and all participants (i.e. nodes) can freely join and exit the network, and carry out relevant operations according to their wishes

On the contrary, the write permission of the network is fully controlled by an organization or institution, and the data read permission is regulated by the organization, either open to the outside world or with a certain degree of access restrictions

In short, it can be understood as a weakly centralized or multi centralized system. Because the participating nodes are strictly limited and few; Compared with public chain, private chain has shorter time to reach consensus, faster transaction speed, higher efficiency and lower cost

and alliance chain is a blockchain between public chain and private chain, which can realize "partial decentralization"

Each node in the

chain usually has a corresponding entity or organization; Participants join the network through authorization and form a stakeholder alliance to jointly maintain the operation of the blockchain

to some extent, alliance chain also belongs to the category of private chain, but the degree of privatization is different. Therefore, it also has the characteristics of low cost and high efficiency, and is suitable for B2B transactions such as transactions and settlement between different entities

Generally speaking, the public chain has the lowest entry threshold, while the private chain and alliance chain are limited in the degree of openness
