changes seems pretty isolated, I think it's better to target unstable branch instead and rebase/merge changes into |

There was a problem hiding this comment.
might also wanna update getMaxRequestBlobSidecars but it might be removed soon and we might be fine just calculating it where we need it

maybe we get rid of this function altogether and always calculate the value as proposed in ethereum/consensus-specs#4322

This change will likely be in devnet 1. Will follow up in another PR

In devnet-0 the req/resp limits will be wrong then, we should consider doing this already for that devnet, can do it in a separate PR though to keep diff minimal here and focus on blob schedule changes

As pointed out here #7729 (comment) , devnet-0 is still using MAX_BLOBS_PER_BLOCK_ELECTRA and MAX_BLOBS_PER_BLOCK for electra and deneb.
Can hold off making this change until devnet-1

But still, we need to update those values for fulu and later, otherwise we keep using the electra values, I don't think it's a big deal though

this will be problematic, if a beacon node does not yet have BLOB_SCHEDULE or didn't backport deneb/electra values then it won't be able to interop with lodestar vc which is really bad since Obol uses it as primary vc
I think we need to add this as fuluForkRelevant for now, we lose some checks on deneb/electra values but that should be fine, might make it stricter once we know majority/all bns implemented this, or earliest in the backport PR when we remove previous constants

Just realized back port blob schedule to Deneb and Electra is not part of fusaka devnet-0 but devnet-1. Updated to reflect this. |

**Motivation** Follow up to #7729, we need to configure blob schedule for each network. This will become relevant once we fully backport blob schedule to deneb and electra. **Description** Add blob schedule to each network config

…ms (#7859) **Motivation** Follow up to #7729, we need to handle blob schedule separately from generic string comparison of values, otherwise what we compare are shallow stringified arrays. It does not validate the object properties and on length mismatch we just get the following error ``` ✖ Error: Local and remote configs are different BLOB_SCHEDULE different value: [object object] != [object object],[object object] ``` **Description** Add special handling for blob schedule when asserting equal params - deserialize and sort blob schedules - compare length of local and remote blob schedule - then check each entry by comparing `EPOCH` and `MAX_BLOBS_PER_BLOCK`
