A block explorer is a tool that users can visualise a blockchain's history with. Each blockchain can be visualised using many different types of block explorer. Block explorers are usually visual representations of the data collected on an archive node of a blockchain.
A block explorer is a tool that allows users to view real-time information about a blockchain. There are usually multiple block explorers for each blockchain. As each block is processed in a given blockchain, block explorers allow users to view transaction data, addresses, fees, and much more.
 
=== Different block explorers ===
[https://etherscan.io/ Etherscan] is one type of block explorer. This is the most prominent smart-contract chain block explorer. It is used for Ethereum mainnet.
 
[https://bscscan.com/ BSCScan], another block explorer created by the same team as Etherscan, is the block explorer used to visualize the BnB Chain.

=== Block explorer features ===
Some block explorers possess more functionality than others. Indeed, given that Solana currently does not have any public archive nodes, it is impossible to say that it even possesses a block explorer if users cannot a transaction that happened a year ago. Some features present on etherscan:

A block explorer is a tool that allows users to view real-time information about a blockchain. There are usually multiple block explorers for each blockchain. As each block is processed in a given blockchain, block explorers allow users to view transaction data, addresses, fees, and much more.
