Block Explorer

    A block explorer is an application (or website) that displays information and the status of transactions for a given blockchain network. Block explorers provide an interface for users to view, query, and navigate a blockchain. Users can explore transaction information such as sender, receiver, and amounts; check the balance of addresses; trace transactions associated with a particular wallet; or see what smart contracts have been deployed on the blockchain. Block explorers run their own nodes (to become part of the blockchain network) and index transaction information relevant to their users. Users can easily access blockchain data to monitor transactions or verify that a transaction has occurred without running their own node. Block explorers are used to exploring both public blockchains and private blockchains. However, not all blockchains provide block explorer access. Private and permissioned blockchains may restrict access or limit it to participants only.
