type Oracle

type Oracle struct {
	log.Log
	// contains filtered or unexported fields
}

Oracle is the hare eligibility oracle.

func New

func New(
	beacons system.BeaconGetter,
	atxdb atxProvider,
	meshdb meshProvider,
	vrfVerifier verifierFunc,
	vrfSigner *signing.VRFSigner,
	layersPerEpoch uint32,
	cfg config.Config,
	logger log.Log) *Oracle

New returns a new eligibility oracle instance.

func (*Oracle) CalcEligibility added in v1.0.0

func (o *Oracle) CalcEligibility(ctx context.Context, layer types.LayerID, round uint32, committeeSize int,
	id types.NodeID, vrfSig []byte) (uint16, error)

CalcEligibility calculates the number of eligibilities of ID on the given Layer where msg is the VRF message, sig is the role proof and assuming commSize as the expected committee size.

func (*Oracle) IsIdentityActiveOnConsensusView

func (o *Oracle) IsIdentityActiveOnConsensusView(ctx context.Context, edID string, layer types.LayerID) (bool, error)

IsIdentityActiveOnConsensusView returns true if the provided identity is active on the consensus view derived from the specified layer, false otherwise.

func (*Oracle) Proof

func (o *Oracle) Proof(ctx context.Context, layer types.LayerID, round uint32) ([]byte, error)

Proof returns the role proof for the current Layer & Round.

func (*Oracle) Validate added in v1.0.0

func (o *Oracle) Validate(ctx context.Context, layer types.LayerID, round uint32, committeeSize int, id types.NodeID, sig []byte, eligibilityCount uint16) (bool, error)

Validate validates the number of eligibilities of ID on the given Layer where msg is the VRF message, sig is the role proof and assuming commSize as the expected committee size.
