-## [v7.1.2](https://github.com/prysmaticlabs/prysm/compare/v7.1.1...v7.1.2) - 2026-01-07
-
-Happy new year! This patch release is very small. The main improvement is better management of pending attestation aggregation via [PR 16153](https://github.com/OffchainLabs/prysm/pull/16153).
-
-### Added
-
-- `primitives.BuilderIndex`: SSZ `uint64` wrapper for builder registry indices. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16169)
-
-### Changed
-
-- the /eth/v2/beacon/pool/attestations and /eth/v1/beacon/pool/sync_committees now returns a 503 error if the node is still syncing, the rest api is also working in a similar process to gRPC broadcasting immediately now. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16152)
-- `validateDataColumn`: Remove error logs. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16157)
-- Pending aggregates: When multiple aggregated attestations only differing by the aggregator index are in the pending queue, only process one of them. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16153)
-
-### Fixed
-
-- Fix the missing fork version object mapping for Fulu in light client p2p. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16151)
-- Do not process slots and copy states for next epoch proposers after Fulu. [[PR]](https://github.com/prysmaticlabs/prysm/pull/16168)

+Data column sidecars storage documentation
+==========================================
+
+File organisation
+-----------------
+- The first byte represents the version of the file structure (up to 0xff = 255).
+  We set it to 0x01.
+  Note: This is not strictly needed, but it will help a lot if, in the future,
+        we want to modify the file structure.
+- The next 4 bytes represents the size of a SSZ encoded data column sidecar.
+  (See the `Computation of the maximum size of a DataColumnSidecar` section to a description
+  of how this value is computed).
+- The next 128 bytes represent the index in the file of a given column.
+  The first bit of each byte in the index is set to 0 if there is no data column,
+  and set to 1 if there is a data column.
+  The remaining 7 bits (from 0 to 127) represent the index of the data column.
+  This sentinel bit is needed to distinguish between the column with index 0 and no column.
+  Example: If the column with index 5 is in the 3th position in the file, then indices[5] = 0x80 + 0x03 = 0x83.
+- The rest of the file is a repeat of the SSZ encoded data column sidecars.
+
+
+|------------------------------------------|------------------------------------------------------------------------------------|

+
+Each file is named after the block root where the data columns were data columns are committed to.
+Example: `0x259c6d2f6a0bb75e2405cea7cb248e5663dc26b9404fd3bcd777afc20de91c1e.sszs`
+
+Database organisation
+---------------------
+SSZ encoded data column sidecars are stored following the `by-epoch` layout.
+- The first layer is a directory corresponding to the `period`, which corresponds to the epoch divided by the 4096.
+- The second layer is a directory corresponding to the epoch.
+- Then all files are stored in the epoch directory.

-# Data column sidecars
-
-## File organisation
-
-- The first byte represents the version of the file structure (up to `0xff = 255`).
-  We set it to `0x01`.
-
-  _(Note: This is not strictly needed, but it will help a lot if, in the future, we want to modify the file structure.)_
-
-- The next 4 bytes represents the size of a SSZ encoded data column sidecar.
-  (See the [Computation of the maximum size of a DataColumnSidecar](#computation-of-the-maximum-size-of-a-datacolumnsidecar) section for a description
-  of how this value is computed).
-
-- The next 128 bytes represent the index in the file of a given column.
-  The first bit of each byte in the index is set to 0 if there is no data column,
-  and set to 1 if there is a data column.
-  The remaining 7 bits (from 0 to 127) represent the index of the data column.
-  This sentinel bit is needed to distinguish between the column with index 0 and no column.
-
-  **Example:** If the column with index 5 is in the 3rd position in the file, then `indices[5] = 0x80 + 0x03 = 0x83`.
-
-- The rest of the file is a repeat of the SSZ encoded data column sidecars.
-
-### File layout
-
-| Byte offset | Description |
-|-------------|-------------|
-| `0` | `version (1 byte) \| sszEncodedDataColumnSidecarSize (4 bytes) \| indices (128 bytes)` |
-| `133 + 0×sszEncodedDataColumnSidecarSize` | `sszEncodedDataColumnSidecar (sszEncodedDataColumnSidecarSize bytes)` |
-| `133 + 1×sszEncodedDataColumnSidecarSize` | `sszEncodedDataColumnSidecar (sszEncodedDataColumnSidecarSize bytes)` |
-| `133 + 2×sszEncodedDataColumnSidecarSize` | `sszEncodedDataColumnSidecar (sszEncodedDataColumnSidecarSize bytes)` |
-| ... | ... |
-| `133 + 127×sszEncodedDataColumnSidecarSize` | `sszEncodedDataColumnSidecar (sszEncodedDataColumnSidecarSize bytes)` |
-
-Each file is named after the block root where the data columns are committed to.
-
-**Example:** `0x259c6d2f6a0bb75e2405cea7cb248e5663dc26b9404fd3bcd777afc20de91c1e.sszs`
-
-## Database organisation
-
-SSZ encoded data column sidecars are stored following the `by-epoch` layout.
-
-- The first layer is a directory corresponding to the `period`, which corresponds to the epoch divided by 4096.
-- The second layer is a directory corresponding to the epoch.
-- Then all files are stored in the epoch directory.

-### Size breakdown
-
-| Field | Calculation | Size |
-|-------|-------------|------|
-| `index` | `ColumnIndex` | `2 bytes` |
-| `column` | `4,096 (MAX_BLOB_COMMITMENTS_PER_BLOCK) × 64 (FIELD_ELEMENTS_PER_CELL) × 32 bytes (BYTES_PER_FIELD_ELEMENT)` | `8,388,608 bytes` |
-| `kzg_commitments` | `4,096 (MAX_BLOB_COMMITMENTS_PER_BLOCK) × 48 bytes (KZGCommitment)` | `196,608 bytes` |

-| `signed_block_header` | `2 bytes (Slot) + 2 bytes (ValidatorIndex) + 3 × 2 bytes (Root) + 96 bytes (BLSSignature)` | `106 bytes` |
-| `kzg_commitments_inclusion_proof` | `4 (KZG_COMMITMENTS_INCLUSION_PROOF_DEPTH) × 32 bytes` | `128 bytes` |
-
-**TOTAL:** `8,782,060 bytes = 70,256,480 bits`
-
-```
-log(70,256,480) / log(2) ≈ 26.07
-```
-
-**Conclusion:** 32 bits (4 bytes) are enough to store the maximum size of a data column sidecar.
-
-The maximum size of an SSZ encoded data column can be `2³² bits = 536,879,912 bytes`,
-which leaves a room of `536,879,912 bytes - 8,782,060 bytes ≈ 503 megabytes` to store the extra data needed by SSZ encoding (which is more than enough).

-# Execution proofs
-
-## File organisation
-
-Unlike data column sidecars (which have a fixed size per block), execution proofs have variable sizes.
-To handle this, we use an offset table that stores the position and size of each proof.
-
-- The first byte represents the version of the file structure (up to `0xff = 255`).
-  We set it to `0x01`.
-
-- The next 64 bytes represent the offset table with 8 slots (one per proof type).
-  Each slot contains:
-  - 4 bytes for the offset (relative to end of header)
-  - 4 bytes for the size of the SSZ-encoded proof
-
-  If the size is 0, the proof is not present.
-
-- The rest of the file contains the SSZ encoded proofs, stored contiguously.
-
-### File layout
-
-| Byte offset | Description |
-|-------------|-------------|
-| `0` | `version (1 byte) \| offsetTable (64 bytes)` |
-| `65 + offsetTable[0].offset` | `sszEncodedProof (offsetTable[0].size bytes)` |
-| `65 + offsetTable[1].offset` | `sszEncodedProof (offsetTable[1].size bytes)` |
-| ... | ... |
-| `65 + offsetTable[7].offset` | `sszEncodedProof (offsetTable[7].size bytes)` |
-
-**Header size:** 1 (version) + 64 (offset table) = **65 bytes**
-
-### Offset table entry format
-
-Each slot in the offset table (8 bytes per slot):
-- `offset` (4 bytes, big-endian): Offset from end of header where proof data begins
-- `size` (4 bytes, big-endian): Size of the SSZ-encoded proof in bytes
-
-**Note:** Offsets are relative to the end of the header (byte 65), not the start of the file.
-This maximizes the usable range of the 4-byte offset field.
-
-### Reading a proof with `proofID=N (O(1) access)`
-
-1. Read header (65 bytes)
-2. Check slot N: if `size == 0`, proof not present
-3. Seek to `(65 + offset)`, read `size` bytes, SSZ unmarshal
-
-Each file is named after the block root.
-
-**Example:** `0x259c6d2f6a0bb75e2405cea7cb248e5663dc26b9404fd3bcd777afc20de91c1e.sszs`
-
-## Database Organisation
-
-SSZ encoded execution proofs are stored following the same `by-epoch` layout as data column sidecars.
-
-- The first layer is a directory corresponding to the `period`, which corresponds to the epoch divided by 4096.
-- The second layer is a directory corresponding to the epoch.
-- Then all files are stored in the epoch directory.
