## Table Description

The `beacon.blobs` table stores blob sidecar data that is exchanged between validators and users on the Beacon network. This table is partitioned by block\_date.

## Column Descriptions

| **Column**                            | **Type**  | **Description**                                                                                 |
| ------------------------------------- | --------- | ----------------------------------------------------------------------------------------------- |
| **block\_epoch**                      | long      | Epoch number when the block containing the blob sidecar was proposed.                           |
| **block\_slot**                       | long      | Slot number within the epoch when the block containing the blob sidecar was proposed.           |
| **block\_time**                       | timestamp | Timestamp when the block containing the blob sidecar was included in the chain.                 |
| **block\_date**                       | date      | Date corresponding to the block\_time.                                                          |
| **index**                             | long      | Index of the blob sidecar within the block.                                                     |
| **proposer\_index**                   | long      | Validator index of the block proposer.                                                          |
| **kzg\_commitment**                   | binary    | KZG commitment for the blob, ensuring data availability and integrity.                          |
| **kzg\_commitment\_inclusion\_proof** | binary    | Proof that the KZG commitment is included in the block, verifying its validity.                 |
| **kzg\_proof**                        | binary    | KZG proof associated with the blob, used for data verification.                                 |
| **body\_root**                        | binary    | Root hash of the block body, representing its contents.                                         |
| **parent\_root**                      | binary    | Root hash of the parent block, linking to the previous block in the chain.                      |
| **state\_root**                       | binary    | Root hash of the state after processing the block, reflecting the system's state.               |
| **signature**                         | binary    | BLS signature of the block proposer, ensuring authenticity.                                     |
| **blob**                              | binary    | The actual blob data associated with the sidecar, containing arbitrary data stored temporarily. |
