Bitcoin Blockchain: Explained Simply 🧱

The Bitcoin blockchain is a decentralized digital ledger that records every Bitcoin transaction ever made. Instead of being stored on one computer, it's maintained by thousands of nodes around the world. Each group of transactions is bundled into a block, and blocks are linked together chronologically—hence the name blockchain.

New blocks are added via a process called mining, where powerful computers solve complex puzzles. This ensures security and prevents fraud. Every 10 minutes, a new block is added, confirming recent transactions.

The system runs without central control, making it trustless, transparent, and tamper-resistant. That’s why it’s called a revolution in digital money.
