1. What Is Blockchain? (Explained Simply)
Imagine a digital ledger—like a shared Google Sheet—that everyone can see but no one can secretly edit. That’s blockchain technology.
At its core:
- Data is stored in blocks.
- Blocks are linked (or chained) together in sequence.
- Once added, information cannot be altered without network approval.
This makes blockchain:
- Decentralized – No single company “owns” it.
- Transparent – Anyone can verify transactions.
- Secure – Cryptography keeps hackers at bay.

2. How Does Blockchain Technology Work?
Let’s break it into three easy steps:
- Transaction Creation – You initiate a transaction (e.g., sending crypto).
- Validation – A network of computers (nodes) verifies it using algorithms.
- Block Addition – The verified transaction joins a block, which is permanently chained to previous blocks.
Think of it as crowdsourced bookkeeping—but far more secure.
3. Types of Blockchain Technology (And Which One You Need) 🔍
Not all blockchains are created equal. Here are the four main types:

| Public Blockchain | Anyone | Cryptocurrencies like Bitcoin & Ethereum |
| Private Blockchain | Authorized users only | Enterprise solutions (e.g., supply chain) |
