A Block Explorer is like Google Maps for the Bitcoinblockchain - it's a tool that lets you navigate and explore all the blocks, transactions, and addresses on the network. It's like having a searchable map of every Bitcoin that's ever changed hands.
Example
"If you want to check the status of a Bitcoin transaction, you can plug the transaction ID into a Block Explorer and see where it is in the blockchain."
"Block Explorers are a handy way to track the flow of BTC and see how different addresses and entities are interacting on the Bitcoin network."
