 What is Blockchain? Simplified in 30 Seconds!

Blockchain is a digital ledger that securely records transactions across a network of computers. Think of it as a chain of blocks, where each block contains data, like transactions, linked in chronological order. What makes it special? It’s decentralized—no single authority controls it—and highly secure, thanks to cryptography. Every transaction is transparent and immutable, meaning it can’t be altered once recorded. Blockchain powers cryptocurrencies like Bitcoin and enables innovations like DeFi and NFTs. It’s the backbone of the future digital economy!
