Cryptocurrency is a digital form of money that operates without a central authority like a bank or government.

Since the launch of Bitcoin in 2009, cryptocurrencies have grown into a global financial system with millions of users worldwide.

What Is Blockchain Technology?
Blockchain is the backbone of cryptocurrency. It is a distributed ledger that records all transactions across a network of computers (nodes).
How Blockchain Works:
A transaction is created
It is verified by network nodes
The transaction is added to a block
The block is linked to previous blocks
Data becomes permanent and unchangeable
This system ensures security, transparency, and trust.
