<Parameter type={"object"} optional={true}>

### Result:
|
|
|
|
The result will be an RpcResponse JSON object with `value` set to a JSON object with the following fields:
|
|
|
|
- `blockhash: <string>` - a Hash as base-58 encoded string
|
|
- `feeCalculator: <object>` - FeeCalculator object, the fee schedule for this block hash
|
|
- `lastValidSlot: <u64>` - DEPRECATED - this value is inaccurate and should not be relied upon
|
|
