Types

type MockactiveSetCache

type MockactiveSetCache struct {
	// contains filtered or unexported fields
}

MockactiveSetCache is a mock of activeSetCache interface.

func NewMockactiveSetCache

func NewMockactiveSetCache(ctrl *gomock.Controller) *MockactiveSetCache

NewMockactiveSetCache creates a new mock instance.

func (*MockactiveSetCache) Add

func (m *MockactiveSetCache) Add(key types.EpochID, value *cachedActiveSet) bool

Add mocks base method.

func (*MockactiveSetCache) EXPECT

func (m *MockactiveSetCache) EXPECT() *MockactiveSetCacheMockRecorder

EXPECT returns an object that allows the caller to indicate expected use.

func (*MockactiveSetCache) Get

func (m *MockactiveSetCache) Get(key types.EpochID) (*cachedActiveSet, bool)

Get mocks base method.

type MockactiveSetCacheMockRecorder

type MockactiveSetCacheMockRecorder struct {
	// contains filtered or unexported fields
}

MockactiveSetCacheMockRecorder is the mock recorder for MockactiveSetCache.

func (*MockactiveSetCacheMockRecorder) Add

func (mr *MockactiveSetCacheMockRecorder) Add(key, value interface{}) *gomock.Call

Add indicates an expected call of Add.

func (*MockactiveSetCacheMockRecorder) Get

func (mr *MockactiveSetCacheMockRecorder) Get(key interface{}) *gomock.Call

Get indicates an expected call of Get.

type MockvrfVerifier

type MockvrfVerifier struct {
	// contains filtered or unexported fields
}

MockvrfVerifier is a mock of vrfVerifier interface.

func NewMockvrfVerifier

func NewMockvrfVerifier(ctrl *gomock.Controller) *MockvrfVerifier

NewMockvrfVerifier creates a new mock instance.

func (*MockvrfVerifier) EXPECT

func (m *MockvrfVerifier) EXPECT() *MockvrfVerifierMockRecorder

EXPECT returns an object that allows the caller to indicate expected use.

func (*MockvrfVerifier) Verify

func (m *MockvrfVerifier) Verify(nodeID types.NodeID, msg []byte, sig types.VrfSignature) bool

Verify mocks base method.

type MockvrfVerifierMockRecorder

type MockvrfVerifierMockRecorder struct {
	// contains filtered or unexported fields
}

MockvrfVerifierMockRecorder is the mock recorder for MockvrfVerifier.

func (*MockvrfVerifierMockRecorder) Verify

func (mr *MockvrfVerifierMockRecorder) Verify(nodeID, msg, sig interface{}) *gomock.Call

Verify indicates an expected call of Verify.

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,
	db *datastore.CachedDB,
	vrfVerifier vrfVerifier,
	vrfSigner *signing.VRFSigner,
	layersPerEpoch uint32,
	cfg config.Config,
	logger log.Log,
) *Oracle

New returns a new eligibility oracle instance.

func (*Oracle) ActiveSet

func (o *Oracle) ActiveSet(ctx context.Context, targetEpoch types.EpochID) ([]types.ATXID, error)

func (*Oracle) CalcEligibility

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

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

func (*Oracle) UpdateActiveSet

func (o *Oracle) UpdateActiveSet(epoch types.EpochID, activeSet []types.ATXID)

func (*Oracle) Validate

func (o *Oracle) Validate(ctx context.Context, layer types.LayerID, round uint32, committeeSize int, id types.NodeID, sig types.VrfSignature, 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.

type VrfMessage

type VrfMessage struct {
	Type   types.EligibilityType // always types.EligibilityHare
	Beacon types.Beacon
	Round  uint32
	Layer  types.LayerID
}

VrfMessage is a verification message. It is also the payload for the signature in `types.HareEligibility`.

func (*VrfMessage) DecodeScale

func (t *VrfMessage) DecodeScale(dec *scale.Decoder) (total int, err error)

func (*VrfMessage) EncodeScale

func (t *VrfMessage) EncodeScale(enc *scale.Encoder) (total int, err error)
