What is a Bitcoin block explorer?

A Bitcoin block explorer is a web-based tool that allows users to search and navigate the blockchain. It provides detailed information about individual Bitcoin blocks, addresses, and transactions. Block explorers can also be used to monitor network activity and to look for suspicious activity.

With a block explorer, users can view the contents of a Bitcoin block, including the number of transactions it contains, the size of the block, the date and time it was created, the list of transactions it contains, and the list of addresses associated with those transactions. A block explorer also allows users to search for specific transactions and view their current status. Additionally, users can view the balances of their Bitcoin wallets and the transactions associated with them.
