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).
