}

func NewClientState 

func NewClientState(
	chainID string, trustLevel Fraction,
	trustingPeriod, ubdPeriod, maxClockDrift time.Duration,
	latestHeight clienttypes.Height, specs []*ics23.ProofSpec,
	upgradePath []string, allowUpdateAfterExpiry, allowUpdateAfterMisbehaviour bool,
) *ClientState

NewClientState creates a new ClientState instance

func (ClientState) CheckHeaderAndUpdateState 

func (cs ClientState) CheckHeaderAndUpdateState(
	ctx sdk.Context, cdc codec.BinaryCodec, clientStore sdk.KVStore,
	header exported.Header,
) (exported.ClientState, exported.ConsensusState, error)

CheckHeaderAndUpdateState checks if the provided header is valid, and if valid it will: create the consensus state for the header.Height and update the client state if the header height is greater than the latest client state height It returns an error if: - the client or header provided are not parseable to tendermint types - the header is invalid - header height is less than or equal to the trusted header height - header revision is not equal to trusted header revision - header valset commit verification fails - header timestamp is past the trusting period in relation to the consensus state - header timestamp is less than or equal to the consensus state timestamp

UpdateClient may be used to either create a consensus state for: - a future height greater than the latest client state height - a past height that was skipped during bisection If we are updating to a past height, a consensus state is created for that height to be persisted in client store If we are updating to a future height, the consensus state is created and the client state is updated to reflect the new latest height UpdateClient must only be used to update within a single revision, thus header revision number and trusted height's revision number must be the same. To update to a new revision, use a separate upgrade path Tendermint client validity checking uses the bisection algorithm described in the [Tendermint spec](https://github.com/tendermint/spec/blob/master/spec/consensus/light-client.md).

Misbehaviour Detection: UpdateClient will detect implicit misbehaviour by enforcing certain invariants on any new update call and will return a frozen client. 1. Any valid update that creates a different consensus state for an already existing height is evidence of misbehaviour and will freeze client. 2. Any valid update that breaks time monotonicity with respect to its neighboring consensus states is evidence of misbehaviour and will freeze client. Misbehaviour sets frozen height to {0, 1} since it is only used as a boolean value (zero or non-zero).

Pruning: UpdateClient will additionally retrieve the earliest consensus state for this clientID and check if it is expired. If it is, that consensus state will be pruned from store along with all associated metadata. This will prevent the client store from becoming bloated with expired consensus states that can no longer be used for updates and packet verification.

func (ClientState) CheckMisbehaviourAndUpdateState 

func (cs ClientState) CheckMisbehaviourAndUpdateState(
	ctx sdk.Context,
	cdc codec.BinaryCodec,
	clientStore sdk.KVStore,
	misbehaviour exported.Misbehaviour,
) (exported.ClientState, error)

CheckMisbehaviourAndUpdateState determines whether or not two conflicting headers at the same height would have convinced the light client.

NOTE: consensusState1 is the trusted consensus state that corresponds to the TrustedHeight of misbehaviour.Header1 Similarly, consensusState2 is the trusted consensus state that corresponds to misbehaviour.Header2 Misbehaviour sets frozen height to {0, 1} since it is only used as a boolean value (zero or non-zero).

func (ClientState) CheckSubstituteAndUpdateState 

func (cs ClientState) CheckSubstituteAndUpdateState(
	ctx sdk.Context, cdc codec.BinaryCodec, subjectClientStore,
	substituteClientStore sdk.KVStore, substituteClient exported.ClientState,
) (exported.ClientState, error)

CheckSubstituteAndUpdateState will try to update the client with the state of the substitute if and only if the proposal passes and one of the following conditions are satisfied:

  1. AllowUpdateAfterMisbehaviour and Status() == Frozen
  2. AllowUpdateAfterExpiry=true and Status() == Expired

The following must always be true:

  • The substitute client is the same type as the subject client
  • The subject and substitute client states match in all parameters (expect frozen height, latest height, and chain-id)

In case 1) before updating the client, the client will be unfrozen by resetting the FrozenHeight to the zero Height. If a client is frozen and AllowUpdateAfterMisbehaviour is set to true, the client will be unexpired even if AllowUpdateAfterExpiry is set to false.

func GetNextConsensusState

}

Header defines the Tendermint client consensus Header. It encapsulates all the information necessary to update from a trusted Tendermint ConsensusState. The inclusion of TrustedHeight and TrustedValidators allows this update to process correctly, so long as the ConsensusState for the TrustedHeight exists, this removes race conditions among relayers The SignedHeader and ValidatorSet are the new untrusted update fields for the client. The TrustedHeight is the height of a stored ConsensusState on the client that will be used to verify the new untrusted header. The Trusted ConsensusState must be within the unbonding period of current time in order to correctly verify, and the TrustedValidators must hash to TrustedConsensusState.NextValidatorsHash since that is the last trusted validator set at the TrustedHeight.

type Misbehaviour 

type Misbehaviour struct {
	ClientId string  `protobuf:"bytes,1,opt,name=client_id,json=clientId,proto3" json:"client_id,omitempty" yaml:"client_id"`
	Header1  *Header `protobuf:"bytes,2,opt,name=header_1,json=header1,proto3" json:"header_1,omitempty" yaml:"header_1"`
	Header2  *Header `protobuf:"bytes,3,opt,name=header_2,json=header2,proto3" json:"header_2,omitempty" yaml:"header_2"`
}

Misbehaviour is a wrapper over two conflicting Headers that implements Misbehaviour interface expected by ICS-02

func NewMisbehaviour 

func NewMisbehaviour(clientID string, header1, header2 *Header) *Misbehaviour

NewMisbehaviour creates a new Misbehaviour instance.

func (Misbehaviour) ClientType 

func (misbehaviour Misbehaviour) ClientType() string

ClientType is Tendermint light client

func (*Misbehaviour) Descriptor 

func (*Misbehaviour) Descriptor() ([]byte, []int)

func (Misbehaviour) GetClientID 

func (misbehaviour Misbehaviour) GetClientID() string

GetClientID returns the ID of the client that committed a misbehaviour.

func (Misbehaviour) GetTime 

func (misbehaviour Misbehaviour) GetTime() time.Time

GetTime returns the timestamp at which misbehaviour occurred. It uses the maximum value from both headers to prevent producing an invalid header outside of the misbehaviour age range.

func (*Misbehaviour) Marshal 

func (m *Misbehaviour) Marshal() (dAtA []byte, err error)

func (*Misbehaviour) MarshalTo 

func (m *Misbehaviour) MarshalTo(dAtA []byte) (int, error)
