What Is Blockchain Technology? A Beginner-Friendly Guide

Intro:
Imagine a ledger that isn’t controlled by any one person, can’t be altered once once information is added, and is open for everyone to see. That’s the power of blockchain—a revolutionary technology shaping the future of everything from finance to supply chains.

What is Blockchain?
Blockchain is a decentralized, distributed ledger that records transactions across a network of computers. Instead of storing data on a single server, it spreads data across thousands of nodes, making it secure and nearly impossible to alter.

How It Works:

A transaction is initiated.

It’s verified by network nodes using consensus algorithms.

The verified transaction is added to a "block."

The block is linked to the previous one, forming a chain.

Use Cases of Blockchain:

Cryptocurrency (e.g., Bitcoin, Ethereum)

Supply chain transparency

Digital identity verification

Smart contracts

Decentralized finance (DeFi)

Pros and Cons:
✅ Transparency & Security✅ Eliminates intermediaries❌ Scalability challenges❌ Regulatory uncertainties

Conclusion:
Blockchain is here to stay. The earlier you understand its fundamentals, the better positioned you'll be to leverage its potential.
