Blockchain is the backbone of Bitcoin — a public, digital ledger that records every transaction. Instead of being stored in one place, it’s shared across thousands of computers worldwide, making it highly secure and almost impossible to alter. Each “block” contains a list of transactions, and once verified, it’s linked to the previous block, forming a chain. This decentralized system removes the need for banks or middlemen, allowing peer-to-peer transactions anytime, anywhere.
