What is Blockchain explorer

A blockchain explorer is an online tool which enables users to retrieve and view information about blockchain transactions. Through a blockchain explorer, a user can enter a certain address, private or public, in the designated search space to get all the information about incoming and outgoing transactions. By allowing users to observe transactions and audit them, blockchain explorers safeguard the transparency of the network, one of the core principles blockchain was built on. Among many other applications, users can employ them to track latest and largest transactions or discover information about the rate at which transactions are occurring. The blockchain explorer works by connecting to the blockchain through a node via an API. When a user searches for specific items (transaction, address, or block), it extracts the requested information, organizes it, and displays it in a tabulated form.
