validate EL block hash in Electra when no EL is connected #6407

Closed etan-status closed 4 months ago

etan-status commented 4 months ago

When no EL is connected, it is still required to validate the block hash of ExecutionPayload to prevent attacks that trick us into attesting to a circular chain with invalid in-between block hashes. This is already done through Deneb but was still missing in Electra to be rectified now.
