🧱 What Is Blockchain?
At its core, a blockchain is a secure, decentralized digital ledger. It records data in “blocks” that are chained together and stored across a network of computers. It’s most famous for powering Bitcoin, but the technology has much wider uses.
🔍 How Blockchain Works (Simplified)
- Each block contains a record of transactions or data
- Blocks are linked in order, making them tamper-proof
- The chain is stored across thousands of computers (nodes), increasing security
🌐 Use Cases Beyond Crypto
- Smart Contracts: Self-executing agreements on platforms like Ethereum
- Supply Chain Tracking: Companies like Walmart use blockchain to trace food origins
- Digital Identity: Secure ID systems using blockchain reduce fraud and increase control
- Voting Systems: Transparent and verifiable digital voting
- Healthcare: Storing patient records securely and accessibly
🧠 Why It Matters for the Future
Blockchain is about trust, transparency, and decentralization. As the internet evolves into Web3, understanding this tech gives you a head start in future-proofing your knowledge and business.
