getdifficulty - Bitcoin Cash

Example code for the getdifficulty JSON-RPC method. Complete guide on how to use the getdifficulty JSON-RPC method in the GetBlock Web3 documentation.

This method returns the proof-of-work difficulty as a multiple of the minimum difficulty. Higher values indicate more hashing work is required per block.

Parameters

This method does not accept any parameters.

Request

        .await?;

    println!("Result: {}", response["result"]);
    Ok(())
}

Response

{
    "error": null,
    "id": "getblock.io",
    "result": 303698825886.4642
}

Response Parameters

Parameter	Type	Description
error	null|object	Error object when the call fails, otherwise null
id	string	Request identifier matching the request
result	numeric	Current proof-of-work difficulty as a multiple of minimum difficulty

Use Cases

• Mining Estimates: Estimate expected time to find a block at a given hash rate

• Hashrate Derivation: Combine with block interval to approximate network hashrate

• Difficulty Charts: Track difficulty adjustments over time

• Profitability Models: Feed difficulty into mining revenue calculations

Error Handling

Error Code	Message	Description
-32700	Parse error	Request body is not valid JSON
-32600	Invalid request	The JSON sent is not a valid request object
-32603	Internal error	Node failed to read the requested chain state
