## Parameters

**`config`** · object · optional

Configuration object

**`commitment`** · string · default `finalized`

Values: `processed`, `confirmed`, `finalized`

Solana RPC uses the following commitment levels:

| Value       | Description                                                                                                                                                                        |
| ----------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `processed` | Return data from the highest slot this node has processed on the fork it currently considers best. This is the newest view, but it can still change if the cluster switches forks. |
| `confirmed` | Return data from the highest slot the cluster has finalized. On Alpenglow, `confirmed` and `finalized` are the same level.                                                         |
| `finalized` | Return data from the highest slot that the cluster has finalized. On Alpenglow there are no vote towers or lockouts: a slot is finalized by certificates of aggregated votes.      |

**`identity`** · string

Return only entries for this validator identity, as a base-58 encoded string.

**`range`** · object

Slot range to return block production for. If parameter not provided, defaults to current epoch.

| Field       | Type  | Description                                                                                                                                       |
| ----------- | ----- | ------------------------------------------------------------------------------------------------------------------------------------------------- |
| `firstSlot` | `u64` | First slot for which to return block-production information, inclusive.                                                                           |
| `lastSlot`  | `u64` | Last slot for which to return block-production information, inclusive. If omitted, defaults to the current slot at the selected commitment level. |

## Response

```json
{
  "jsonrpc": "2.0",
  "result": {
    "context": {
      "apiVersion": "4.3.2",
      "slot": 9887
    },
    "value": {
      "byIdentity": {
        "85iYT5RuzRTDgjyRa3cP8SYhM2j21fj7NhfJ3peu1DPr": [9888, 9886]
      },
      "range": {
        "firstSlot": 0,
        "lastSlot": 9887
      }
    }
  },
  "id": 1
}

| --------------------- | ---------------- | ---------------------------------------------------------------------------- |
| `<validatorIdentity>` | `[usize, usize]` | Map entry keyed by a validator identity pubkey, as a base-58 encoded string. |

**`byIdentity` tuple indexes**

| Index | Type    | Description                                                               |
| ----- | ------- | ------------------------------------------------------------------------- |
| `0`   | `usize` | Number of leader slots assigned to that validator in the requested range. |
| `1`   | `usize` | Number of blocks that validator actually produced in that range.          |

**`range` fields**

| Field       | Type  | Description                                                   |
