Motivation

  • Improve processSlashings() which only run when there are validators getting slashed

Description

  • Resolves all TODOs for state.slashings:
    • Cache total slashings in EpochCache so that we don't need to compute in processSlashings
    • With that we can store state.slashings as number[] instead of BigInt[]
  • Update slashing penalties once in processRewardsAndPenalties
  • Also no need to recompute slashing penalties for validators with the same effective balance

part of #6112

part of #5892

Testing

  • This reduces the processSlashing() to almost zero cost.
  • Before
phase0 processSlashings
✔ phase0 processSlashings - 250000 worstcase                          377.9087 ops/s    2.646142 ms/op        -        858 runs   14.7 s
  • After
phase0 processSlashings
✔ phase0 processSlashings - 250000 worstcase                          10352.72 ops/s    96.59300 us/op        -       1647 runs   14.0 s

effectiveBalanceIncrements is populated with validator count and increased its length per processDeposit so the default value for any validator index is always 0

I also doubled check all use of effectiveBalanceIncrements, we don't need to handle undefined there so I think we don't need to do it here too. For example

lodestar/packages/state-transition/src/block/processAttestationsAltair.ts

Line 111 in 3f3a207

epochCtx.currentTargetUnslashedBalanceIncrements += effectiveBalanceIncrements[index];

packages/state-transition/src/block/slashValidator.ts Outdated
const slashingIndex = epoch % EPOCHS_PER_SLASHINGS_VECTOR;
state.slashings.set(slashingIndex, state.slashings.get(slashingIndex) + BigInt(effectiveBalance));
state.slashings.set(slashingIndex, state.slashings.get(slashingIndex) + effectiveBalance);
