A blockchain is a distributed ledger — a record of transactions copied across thousands of computers worldwide. No single entity controls it, and once data is confirmed, it’s extremely difficult to alter, thanks to cryptographic linking between blocks.

This structure is what enables trustless transactions: you don’t need to trust a middleman, just the math and the network’s consensus. It’s the foundation crypto is built on, not the coins themselves.
