Definition
A block explorer is an online tool that lets users look up public data stored on a blockchain. It provides a searchable view of blocks, transactions, addresses, and other on-chain records. As an interface to the underlying ledger, a block explorer displays information that has already been recorded and confirmed on the network in a readable, organized format.
In Simple Terms
A block explorer is like a public search window into a blockchain. It shows what has been recorded on the chain, such as transactions, blocks, and addresses. Anyone can use it to look up this information in a clear, easy-to-read way, based on data that is already stored on the blockchain.
Context and Usage
Block explorers are commonly used when people want to check the status or details of blockchain activity. They are referenced in discussions about verifying transactions, reviewing block contents, or viewing the history linked to a specific address. In many blockchain communities, a block explorer is treated as the main reference point for reading on-chain data and confirming what the ledger currently shows.
