Bitcoin RPC
Overview
The getblockhash method is part of the Bitcoin JSON-RPC API, which is used to interact with the Bitcoin blockchain. This method is specifically designed to return the hash of a block given its height in the blockchain. The height is a numeric value that represents the position of the block in the blockchain, starting from 0 for the genesis block.
Parameters
height: This is a required parameter. It is a numeric value that specifies the height index of the block in the blockchain. The height index is used to identify a block uniquely within the blockchain.
Returns
result: The method returns the hash of the block corresponding to the provided height. This hash is a unique identifier for the block in the Bitcoin blockchain.error: If there is an error in processing the request, the method will return an error message detailing the issue.
