Functions

func IsAttAggregator

func IsAttAggregator(ctx context.Context, specProvider eth2client.SpecProvider, commLen uint64, slotSig eth2p0.BLSSignature) (bool, error)

IsAttAggregator returns true if the validator is the attestation aggregator for the given committee. Refer: https://github.com/ethereum/consensus-specs/blob/dev/specs/phase0/validator.md#aggregation-selection

func IsSyncCommAggregator

func IsSyncCommAggregator(ctx context.Context, specProvider eth2client.SpecProvider, sig eth2p0.BLSSignature) (bool, error)

IsSyncCommAggregator returns true if the validator is the aggregator for the provided sync subcommittee. Refer: https://github.com/ethereum/consensus-specs/blob/dev/specs/altair/validator.md#aggregation-selection

Types

type BeaconCommitteeSelection

type BeaconCommitteeSelection struct {
	// ValidatorIdex is the index of the validator making the aggregate request.
	ValidatorIndex eth2p0.ValidatorIndex
	// Slot is the slot for which the validator is possibly aggregating.
	Slot eth2p0.Slot
	// SelectionProof is the slot signature required to calculate whether the validator is an aggregator.
	SelectionProof eth2p0.BLSSignature
}

BeaconCommitteeSelection is the data required for a beacon committee subscription.

func (*BeaconCommitteeSelection) MarshalJSON

func (b *BeaconCommitteeSelection) MarshalJSON() ([]byte, error)

MarshalJSON implements json.Marshaler.

func (*BeaconCommitteeSelection) String

func (b *BeaconCommitteeSelection) String() (string, error)

String returns a string version of the structure.

func (*BeaconCommitteeSelection) UnmarshalJSON

func (b *BeaconCommitteeSelection) UnmarshalJSON(input []byte) error

UnmarshalJSON implements json.Unmarshaler.

type BeaconCommitteeSelectionAggregator

type BeaconCommitteeSelectionAggregator interface {
	// AggregateBeaconCommitteeSelections returns DVT aggregated beacon committee selection proofs.
	// This would call a new BN API endpoint: POST /eth/v1/validator/beacon_committee_selections
	AggregateBeaconCommitteeSelections(ctx context.Context, partialSelections []*BeaconCommitteeSelection) ([]*BeaconCommitteeSelection, error)
}

BeaconCommitteeSelectionAggregator is the interface for aggregating beacon committee selection proofs in a DVT cluster. TODO(dhruv): Should be removed once it is supported by go-eth2-client.

type SyncCommitteeSelection

type SyncCommitteeSelection struct {
	// ValidatorIndex is the index of the validator making the selection request.
	ValidatorIndex eth2p0.ValidatorIndex
	// Slot is the slot for which the selection request is made.
	Slot eth2p0.Slot
	// SubcommitteeIndex is the subcommittee to which the validator is assigned.
	SubcommitteeIndex eth2p0.CommitteeIndex
	// SelectionProof is a partial or an aggregated signature.
	SelectionProof eth2p0.BLSSignature
}

SyncCommitteeSelection is the data required for a sync committee subscription.

func (*SyncCommitteeSelection) MarshalJSON

func (s *SyncCommitteeSelection) MarshalJSON() ([]byte, error)

MarshalJSON implements json.Marshaler.

func (*SyncCommitteeSelection) String

func (s *SyncCommitteeSelection) String() (string, error)

String returns a string version of SyncCommitteeSelection.

func (*SyncCommitteeSelection) UnmarshalJSON

func (s *SyncCommitteeSelection) UnmarshalJSON(input []byte) error

UnmarshalJSON implements json.Unmarshaler.

type SyncCommitteeSelectionAggregator

type SyncCommitteeSelectionAggregator interface {
	// AggregateSyncCommitteeSelections returns the threshold aggregated sync committee selection proofs.
	// This would call a new BN API endpoint: POST /eth/v1/validator/sync_committee_selections
	AggregateSyncCommitteeSelections(ctx context.Context, partialSelections []*SyncCommitteeSelection) ([]*SyncCommitteeSelection, error)
}

SyncCommitteeSelectionAggregator is the interface for aggregating sync committee selection proofs.
