Use case

The getblockhash method is useful for retrieving the hash of a block at a specific height in the blockchain. This can be used in conjunction with other methods like getblock to retrieve detailed information about a particular block.

For example, a block explorer application might use getblockhash to get the hash of the latest block, and then use that hash with getblock to retrieve and display the contents of the latest block.
