+###### Blob retrieval via local execution layer client
+
+In addition to `BlobSidecarsByRoot` requests, recent blobs MAY be retrieved by querying the Execution Layer (i.e. via `engine_getBlobsV1`).
+Implementers are encouraged to leverage this method to increase the likelihood of incorporating and attesting to the last block when its proposer is not able to publish blobs on time.
+
+When clients use the local execution layer to retrieve blobs, they MUST behave as if the corresponding `blob_sidecar` had been received via gossip. In particular they MUST:
+* publish the corresponding `blob_sidecar` on the `blob_sidecar_{subnet_id}` subnet.
+* update gossip rule related data structures (i.e. update the anti-equivocation cache).
