Blockchain 101: What You Need to Know
If you're new to crypto, understanding blockchain is your first step.

Think of blockchain as a digital ledger that everyone can see but no one can cheat.

Here's why it matters:
- Decentralized - No single person or company controls it. The network runs on thousands of computers worldwide.
- Transparent - Every transaction is recorded and visible to anyone. You can verify everything.
- Secure - Once data is added, it's nearly impossible to change. Each "block" is linked to the previous one, forming a chain.

Why should you care?
Blockchain powers Bitcoin, Ethereum, and thousands of other cryptocurrencies. It's also being used for supply chains, voting systems, and digital ownership (NFTs).

Understanding this foundation will help you make smarter decisions in crypto.
