* eip4844 beacon block proposals
* Don't fetch blobs under minimal preset
@tersec's summary of the issue:
BlobsBundleV1 in the execution API spec assumes a mainnet preset blob
size, where the EIP4844 consensus spec defines
FIELD_ELEMENTS_PER_BLOB: 4 under the minimal preset, which leads to a
Blob having a length of 4 * 32, not 4096 * 32 which BlobsBundleV1
requires.
