What about BlobGasUsed and ExcessBlobGas? The type doesn't have those fields.

not needed as those fields are validated at the builder, this is just an helper struct that grabs the common fields needed for validation at the relay

services/api/types_test.go

database/database_test.go

datastore/redis.go

common/types_spec.go

+type BuilderBlockValidationRequest struct {
+	*VersionedSubmitBlockRequest
+	RegisteredGasLimit    uint64       `json:"registered_gas_limit,string"`
+	ParentBeaconBlockRoot *phase0.Root `json:"parent_beacon_block_root,omitempty"`
 }


Will the validator function allow ParentBeaconBlockRoot to be missing? It doesn't appear to be an optional field in the builder's BuilderBlockValidationRequestV3 struct. Should BuilderBlockValidationRequest (here in the relay) have the omitempty qualifier?

I think the builder's BuilderBlockValidationRequestV3 struct will unmashal to a zero value (0 hash) as it does not validate that it is a required field.

@avalonche I didn't realize that switch statement pattern (falllthrough) was used to appease exhaustive.

@jtraglia yeah I didn't like having to list every version as the code only supports a small subset of the versions, so disabled the linter

PSA: We've deployed this PR (tip of deneb branch 1ffdc1a) to Flashbots mainnet relay.
