A block explorer is a website that reads the blockchain and shows whatever is on it: every transaction, address balance, block, fee, and contract call. Etherscan, Mempool.space, and Solscan are famous examples.

Why it matters

Explorers are the blockchain’s “Google” — you enter a transaction hash or address and see exactly what happened, permanently, for free. Learning to use one is a core verification skill: confirm a payment arrived, check a contract is live, or investigate a suspicious token.
