Background
The original EIP-6110 proposes to process deposits in per-slot block processing which requires clients to store unfinalized validators and their indices in pubkey cache. Our solution was to introduce
unfinalizedPubkey2index
inEpochCache
to separate unfinalized validators with finalized validators in case of re-org.ethereum/consensus-specs#3818 updates EIP-6110 to take advantage of pending deposit queue from EIP-7251 such that
slot
that has been finalized will be processed.As such, re-org will not impact/change validator index assignment of a newly joined validator and thus there is no need for Lodestar to maintain
unfinalizedPubkey2index
.Description
This PR contains the following:
unfinalizedPubkey2index
fromEpochCache
and related perf and memory testhistoricalValidatorLengths
fromEpochCache
EpochCache.pubkey2index
