Renaissance: The Renaissance marked a period of renewed interest in art, literature, science, and exploration, leading to significant advancements in various fields and the beginning of the modern era.5. Industrial Revolution: The Industrial Revolution brought about a massive shift from agrarian economies to industrialized societies, transforming manufacturing, transportation, and communication systems.6. Modern Era: The modern era encompasses various movements and developments, including colonialism, nationalism, two World Wars, the Cold War, globalization, and rapid technological advancements. It can also be called the age of machines, industries and factories. It turned the wheel of development faster. Then the technology progressed and man left the earth and reached the moon. 7.Contemporary Period: The present time is actually a digital age. It includes recent decades marked by digital technology, globalization, and the ongoing evolution of society and culture.
As the capacity of the human mind continued to increase, it continued to develop rapidly in all areas of its life. This development is one of the aspects of human life including academic, economic, social, martial skills, art, and culture.
The digital era began at the end of the last century and the beginning of the present, i.e., the beginning of the 21st century. And since then, digital technology is moving towards a new peak every day, even thanks to digital technology, artificial intelligence has been developed, which seems to surpass human intelligence.
In today's era we are connected to each other using the best technology in different parts of the world. It is also worth noting that after the digital age, we have now left behind paper currency transactions and reached the amazing era of
block chain or crypto currency. Digital technology has given a new and amazing shape to the human world. .
A lot has changed now. Our life is not what it used to be in the last century or thirty or forty years ago.
Take the example of crypto currency, which has emerged so rapidly that it has threatened to end the existence of the traditional system of paper currency notes and banks circulating around the world. A
crypto currency is a digital asset based on block chain technology that can circulate without the centralized authority of a bank or government. As of August 27, 2024, more than 8,000
crypto currencies are in the market, representing a $2.21 trillion market capitalization.
You must have heard about crypto currency, but maybe you don't know much about it. Rather, many people from Pakistan, India, Afghanistan, Bangladesh and many other countries probably know crypto currency by now. You may not even have heard the name.
Here we are going to tell you what crypto currency is, where and how it came into being and how it works.
A crypto currency is a digital or virtual token, block or coin. Although like traditional currency notes and coins, crypto currency does not have a physical form that you can carry in your pocket or wallet, you can transact it like traditional money. and can spend or deposit it. Crypto currencies use secret codes for their safety or security, which is called cryptography. It is not under the control of any institution or person or any central bank and works completely independently. That is, no one can confiscate, steal or manipulate this currency. It has no center or head. There is no quarter. It is based on a decentralized technology called block chain. It is a distributed open ledger that records all transactions of crypto currencies or tokens on its network. .
The name of the world's first crypto-currency is Bitcoin, which was launched in the year 2009. Bitcoin is said to have been created by a man from Japan called “Satoshi Nakamoto”. Bitcoin was designed as a peer-to-peer electronic cash system. This system allows
crypto currency users to send and receive money without the need for a trusted third party, such as a bank or money exchange.
Crypto currency works by using an independent and decentralized network of computers that validate and record transactions on the block chain. Each transaction through the network is verified by a consensus mechanism, such as proof-of-work or proof-of-stake.
Block chain ensures that every transaction of crypto currency or coins is secure and cannot be cheated, altered or tampered with.
The process of creating new units or coins of crypto currency is like mining gold or diamonds from a mine. This process of creating new units of
crypto currency is called mining. Involves solving complex mathematical equations using computational power. This process adds new transactions to the
block chain and generates new units of cryptocurrency as a reward for users who earn new tokens through mining.
Can cryptocurrencies be easily bought and sold?
Yes, cryptocurrencies can be bought and sold on crypto exchanges. Many companies and merchants accept
crypto currencies as a form of payment in exchange for traditional money, so you can buy and sell
crypto currencies from companies and merchants for goods and services. You can also use it to buy services. And the important thing is that you can use

Surely by now most of you must have got the concept of cryptocurrency clear in your mind and have got the basic knowledge about this modern currency of today and future.
In summary, crypto currency is a digital or virtual currency that operates independently of a central bank and is based on decentralized
block chain technology. This digital currency system uses computers to validate and record transactions on the
block chain. It works using a network, and new units of crypto currency, which you can call coins, tokens or blocks, are created through a computational process called mining.
