What is CryptoCurrency? How does it work? What are its advantages and disadvantages?
We know what is currency; which is a physical medium used for transactions between different parties. Currency enables the smooth mutual exchange of goods and services.

The traditional currency exists in a physical form; paper or coins. Normally, it is issued by the government/the Central bank of a country and is accepted as a means of payment at its face value.

Currency replaced the barter system, the old method of exchange that was practiced for centuries.

Compared to this let’s examine what is cryptocurrency.

Cryptocurrency is a new currency, one of the major innovations of the 21st century. It can perform the functions of a traditional currency. What makes it unique and different from the traditional currency is that it doesn’t have a physical form. It is a virtual currency or digital money.

What Is CryptoCurrency After All? How Does Cryptocurrency Work

What is CryptoCurrency

Cryptocurrency is a digital currency that is exchanged online for goods and services. It is exchanged using Blockchain technology, also known as distributed ledger technology.

The Blockchain is a public digital ledger of transactions maintained by a network of computers as blocks, in chronological order. These blocks are linked together or chained with the help of Cryptography.

The ledger can be viewed by all cryptocurrency users. And, every transaction is independently verified by peer-to-peer computer networks, time-stamped, and recorded. Once recorded, the data cannot be changed.

The word “crypto” is derived from the encryption technology or Cryptography that is used to make the network safe and to prevent fraud or interference by third parties. Cryptographic codes, known as “hashes,” or passwords are used to chain and secure the blocks.

Unlike the traditional currency, Cryptocurrency is a free currency with no central authority overseeing the database, or transactions. This currency is not in the control of any single authority. Traditional currencies such as the rupee, dollar, euro, etc., are regulated. In contrast, Cryptocurrency is not controlled by any state, country, institution, or government.

Origin of Crypto Currency

You should know that the first cryptocurrency- Bitcoin- was introduced in 2009. It was made by an engineer named Satoshi Nakamoto of Japan.
