The execution layer provides the RLP-encoded `blockAccessList` to the consensus layer via the Engine API. The consensus layer then computes the SSZ `hash_tree_root` for storage in the `ExecutionPayload`.

**Retrieval methods** for historical BALs (similar to `engine_getPayloadBodiesByHashV1`):
**Retrieval methods** for historical BALs:

- `engine_getBALsByHashV1`: Array of block hashes → Array of RLP-encoded BALs
- `engine_getBALsByRangeV1`: Start block number, count → Array of RLP-encoded BALs
- `engine_getPayloadBodiesByHashV2`: Returns `ExecutionPayloadBodyV2` objects containing transactions, withdrawals, and `blockAccessList`
- `engine_getPayloadBodiesByRangeV2`: Returns `ExecutionPayloadBodyV2` objects containing transactions, withdrawals, and `blockAccessList`

The `blockAccessList` field contains the RLP-encoded BAL or `null` for pre-Amsterdam blocks or when data has been pruned.

The EL MUST retain BALs for at least the duration of the weak subjectivity period (`=3533 epochs`) to support synchronization with re-execution after being offline for less than the WSP.
