What Is Blockchain?

Blockchain is like a shared notebook that records every crypto transaction. It’s a chain of blocks, each holding data—like who sent what to whom. Spread across thousands of computers, it’s secure and can’t be changed. That’s why it powers Bitcoin and more!

How It Works

Each block has a list of transactions, a timestamp, and a unique code (hash). Linked blocks form a chain, and computers (nodes) verify everything. Miners or validators solve puzzles to add blocks, earning rewards. It’s like a global puzzle party!

Types of Blockchains

Public blockchains (like Bitcoin) are open to all. Private ones are for specific groups. Hybrid and consortium versions mix both. Each suits different needs—public for crypto, private for businesses.

Why It Matters

Blockchain’s transparency fights fraud. Smart contracts automate tasks, like renting a car. It’s used beyond crypto—supply chains, voting, you name it! It’s a tech revolution to explore.

Challenges

It’s slow for some uses, and energy use is a concern. Regulations are growing in the U.S., so stay legal. It’s a learning curve—exciting to tackle!
