What is Blockchain? And a Short History
When most people hear “blockchain,” they immediately think Bitcoin. But blockchain is much bigger than just cryptocurrency.
So, what exactly is it?
Blockchain is like a public notebook that everyone can see, but no one can erase or change.
It stores information in blocks, which are linked together in a chain. Each block contains transactions, a timestamp, and a security code (called a hash).
This makes blockchain secure, transparent, and trustworthy — the foundation of Web3.
