Functions of Currency

Currency has multiple functions, which together constitute its core position in the economic system. Each of these features is discussed below.

1. Medium of exchange

One of the most basic functions of money is as a medium of exchange. In the early stages of the development of human society, barter was the main form of transaction. However, this method of exchange has many inconveniences. For example, both parties must have the goods that the other party needs at the same time. The introduction of currency simplified this process and made transactions more convenient.

2. Scale of value

Money serves as a universally accepted measure of value, allowing goods and services to express their value in monetary terms. This standardized value scale provides a fair and efficient means for market economies, making it easier for people to compare the relative value of different goods and services.

3. Storage means

Currency serves as a means of storage, allowing individuals to store wealth for future use. Compared to other forms of storage, such as commodities or gold, the advantage of currency is its relatively small size and portability, making it more convenient to store wealth.

4. Value exchange

Money is not just a medium of exchange but a means used to settle debts and fulfill contracts. In the complex modern economic system, currency, as a universal means of payment, promotes various economic activities. This makes it easier for people to invest, borrow and run businesses.


In this section, we describe the various functions of currency in detail. Next, we'll explore the historical evolution of money. Click "Continue" for Part Three.

The Historical Evolution of Currency

The history of currency can be traced back to ancient times. With the evolution of society, currency forms have undergone many changes.

1. The era of commodity currency

The earliest medium of exchange was physical goods, which was called commodity money. During this era, people engaged in direct barter with actual commodities such as cattle, salt, etc. However, this method of exchange has many inconveniences, especially when the goods needed by both parties do not match.

2. The rise of metal currency

In order to solve the problem of physical exchange, metal currency has gradually become a more convenient medium of exchange. Metal currency has characteristics such as scarcity, durability, and divisibility, making it an ideal form of currency. In ancient times, precious metals such as gold and silver began to be widely used in transactions.

3. Circulation of banknotes and coins

With the continuous development of society, banknotes and coins gradually replaced metal currencies. The emergence of banknotes made currency lighter and easier to carry. The central bank plays an important role in issuing and managing currency in this process, ensuring the stable circulation of currency.

4. The role of central banks

In modern society, the central bank has become the main institution for currency issuance and management. The central bank regulates money supply through monetary policy to maintain currency stability and credit. In addition, the central bank also plays a role in maintaining the stability of the financial system and promoting economic growth in monetary policy.

The Rise of Cryptocurrencies

In recent years, with the rapid development of technology, cryptocurrency as a new form of currency has begun to attract global attention. The birth of Bitcoin marked the beginning of the cryptocurrency era, and blockchain technology became the core of this change.

1. The emergence of Bitcoin

Bitcoin is the first cryptocurrency, proposed and launched in 2009 by Satoshi Nakamoto. Unlike traditional currencies, the transactions and issuance of Bitcoin do not rely on any central organization, but are completed through decentralized blockchain technology. This makes Bitcoin highly transparent and anti-counterfeiting.

2. Application of blockchain technology

The rise of cryptocurrency is mainly due to the application of blockchain technology. Blockchain is a decentralized distributed ledger technology that records all transaction information and ensures data security and non-tamperability. This technology provides a decentralized and secure foundation for cryptocurrencies.

3. Characteristics of decentralization

A distinctive feature of cryptocurrencies is their decentralization, meaning there is no central agency or government regulating them. This allows for freer circulation and use of cryptocurrencies, but also raises some regulatory and compliance controversies.

4. Volatility and regulatory issues

While cryptocurrencies have been successful in some areas, their extreme price volatility has caused concern among some investors. Additionally, the cryptocurrency market is also susceptible to manipulation and misconduct due to the lack of strict legal regulation. These issues have become some of the challenges in the development of cryptocurrency.

It can be a digital legal currency issued by a central bank or an encrypted digital currency based on blockchain technology. Countries have begun to study and experiment with the issuance of digital currencies to adapt to the popularity and development of digital payments.

Some countries have begun to launch their own national digital currencies, aiming to improve payment efficiency, reduce transaction costs, and strengthen the implementation of monetary policy. Compared with traditional digital payment methods, national digital currencies have more legal status and are issued and managed by the government or central bank. They are expected to play an important role in international trade and finance in the future.

3. The impact of innovative technologies on currency

In the future, the development of currency will be affected by various innovative technologies, such as artificial intelligence, big data analysis, the Internet of Things, etc. These technologies will further promote innovation in payment and financial services, making money more intelligent, convenient and secure.
