Functions

func GetBySlotAndCommitteeIndex added in v5.3.0 

func GetBySlotAndCommitteeIndex[T ethpb.Att](c *AttestationCache, slot primitives.Slot, committeeIndex primitives.CommitteeIndex) []T

GetBySlotAndCommitteeIndex returns all attestations in the cache that match the provided slot and committee index. Forkchoice attestations are not returned.

NOTE: This function cannot be declared as a method on the AttestationCache because it is a generic function.

Types

type AttestationCache 

type AttestationCache struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

AttestationCache holds a map of attGroup items that group together all attestations for a single slot. When we add an attestation to the cache by calling Add, we either create a new group with this attestation (if this is the first attestation for some slot) or two things can happen:

  • If the attestation is unaggregated, we add its attestation bit to attestation bits of the first attestation in the group.
  • If the attestation is aggregated, we append it to the group. There should be no redundancy in the list because we ignore redundant aggregates in gossip.

The first bullet point above means that we keep one aggregate attestation to which we keep appending bits as new single-bit attestations arrive. This means that at any point during seconds 0-4 of a slot we will have only one attestation for this slot in the cache.

NOTE: This design in principle can result in worse aggregates since we lose the ability to aggregate some single bit attestations in case of overlaps with incoming aggregates.

The cache also keeps forkchoice attestations in a separate struct. These attestations are used for forkchoice-related operations.

type ProposerIndicesCache 

type ProposerIndicesCache struct {
	sync.Mutex
	// contains filtered or unexported fields
}

ProposerIndicesCache keeps track of the proposer indices in the next two epochs. It is keyed by the state root of the last epoch before. That is, for blocks during epoch 2, for example slot 65, it will be keyed by the state root of slot 63 (last slot in epoch 1). The cache keeps two sets of indices computed, the "safe" set is computed right before the epoch transition into the current epoch. For example for epoch 2 we will compute this list after importing block 63. The "unsafe" version is computed an epoch in advance, for example for epoch 3, it will be computed after importing block 63.

The cache also keeps a map from checkpoints to state roots so that one is able to access the proposer indices list from a checkpoint instead. The checkpoint is the checkpoint for the epoch previous to the requested proposer indices. That is, for a slot in epoch 2 (eg. 65), the checkpoint root would be for slot 32 if present.
