yeah, but we can include it in this pr, but also add it to alloy and once we have a new release we can phase it out here

this is a bit tricky, because this can lead to stack overflow on deserialize on debug...
I encountered this here as well:
see corresponding test
so we ideally want a sanity test and perhaps we also need to do

I think we should definitely box this because we do vec![None; request.len()] so each entry even if missing will be a full blob

I think we can return a servererror in this case

@michaelsproul sorry about the conflicts, |

thanks @mattsse that would be great I started on it locally but got drawn into other things and will likely continue getting distracted thanks for pushing it along! |
This is a prototype implementation of
engine_getBlobsV1, which allows the CL to fetch blobs from the EL to accelerate blob propagation:engine_getBlobsV1ethereum/execution-apis#559Before merging there are a few things that need to be resolved:
get_blobsor whether we should make it infallible (don't return a result).BlobAndProofV1type.
