At its core, cryptocurrency is a form of digital money built on Blockchain. Instead of banks keeping records, transactions are stored across a network of computers, making the system transparent and hard to tamper with. Every transfer is like carving a tiny inscription into a shared stone tablet that everyone can see but no one can secretly edit.


The most famous example is Bitcoin, created in 2009 by the mysterious Satoshi Nakamoto. It introduced the idea that money could exist without a central authority. Since then, thousands of cryptocurrencies have appeared, including Ethereum, which added programmable contracts—tiny self-executing agreements written in code.
