Problem to be solved

Add support for DutyPrepareSyncContribution to fetcher. Fetcher needs to calculate which validators are aggregators for the given slot.

Proposed solution

  • Fetcher queries aggSigDB for DutyPrepareSyncContribution
  • It then filters out the validators that are aggregators using eth2exp.CalculateSyncCommitteeSelection().
  • It also queries DutyDB for DutySyncMessage to get the blockRoot.
  • It then queries the beacon API endpoint GET /eth/v1/validator/sync_committee_contribution to get the sync committee contribution.

Out of Scope

None.
