BLOCK CHAIN is a digital record book that is:
🔒 Secure – once data is added, it can’t be changed
🌍 Decentralized – no single person controls it
📦 Stored in blocks – every block holds data (like transactions)
⛓️ Linked together – each block connects to the previous one, forming a chain
Think of it like a public ledger shared across many computers.
Everyone sees the same information, so it’s hard to cheat or manipulate.
It’s the technology behind Bitcoin, crypto, NFTs, smart contracts, and Web3 apps.
