## Issue Addressed Non-urgent clean-up possible after - https://github.com/sigp/lighthouse/pull/5583 This can wait for after v5.2.0 Currently we are: - Fetching an entire Vec of blocks in the network context -...

Add peers to lookup ancestors

## Description If a peer claims to have imported block A, and we have a parent chain of blocks with block A as tip, then the peer must know about...

Too many `Searching for block components`

**TLDR**: Not actively harmful, just wasted CPU cycles while block and blobs are in the da_checker and we keep getting attestations - Introduced in https://github.com/sigp/lighthouse/pull/5583 17,901 hits on `ho-h-bn-suit` during...

## Issue Addressed Part of - https://github.com/sigp/lighthouse/issues/4983 Allows nodes to fulfill their custody requirements during forward sync and backfill sync. ## Proposed Changes - Some changes on the boilerplate to...

After merging https://github.com/ChainSafe/bls-keystore/pull/6. Extract the functionality used in https://github.com/ChainSafe/lodestar/pull/1110/files/c25b0165ac81f2fbcdef5cc6f383af82b052742d#diff-0f27f9fb8dc6f56bc2af257db4c0c97d into its own `bls-walletstore` NPM package > Ideally we pull this out into a bls-walletstore library https://github.com/ChainSafe/lodestar/pull/1110#discussion_r451215065
