Refer to [Lighthouse API](./api_lighthouse.md#lighthousedatabaseinfo) for an example response.

Alternatively, you can use the [lighthouse API](api_vc_endpoints.md). See below for an example.

Use the [lighthouse API](api_vc_endpoints.md) to enable/disable use of the builder API on a per-validator basis.

Refer to [suggested fee recipient](validator_fee_recipient.md) documentation.

Block builders and relays can query beacon node events from the [Events API](https://ethereum.github.io/beacon-APIs/#/Events/eventstream). An example of querying the payload attributes in the Events API is outlined in [Beacon node API - Events API](./api_bn.md#events-api)

[`/lighthouse/database`](./api_lighthouse.md) APIs.

The following table lists the data for different configurations. Note that the disk space requirement is for the `chain_db` and `freezer_db`, excluding the `blobs_db`.

| Hierarchy Exponents | Storage Requirement | Sequential Slot Query | Uncached Query | Time to Sync |

|---|---|---|---|---|

| 5,9,11,13,16,18,21 (default) | 418 GiB | 250-700 ms | up to 10 s | 1 week |

| 5,7,11 (frequent snapshots) | 589 GiB | 250-700 ms | up to 6 s | 1 week |

| 0,5,7,11 (per-slot diffs) | 2500 GiB | 250-700 ms | up to 4 s | 7 weeks |

[Jim](https://github.com/mcdee) has done some experiments to study the response time of querying random slots (uncached query) for `--hierarchy-exponents 0,5,7,11` (per-slot diffs) and `--hierarchy-exponents 5,9,11,13,17,21` (per-epoch diffs), as show in the figures below. From the figures, two points can be concluded:

- response time (y-axis) increases with slot number (x-axis) due to state growth.

- response time for per-slot configuration in general is 2x faster than that of per-epoch.

In short, setting different configurations is a trade-off between disk space requirement, sync time and response time. The data presented here is useful to help users choosing the configuration that suit their needs.

The first step creates a `validators` directory under `/var/lib/my-custom-dir` which contains the imported keys and [`validator_definitions.yml`](./validator_management.md).
