Functions

func GetProcessedTime 

func GetProcessedTime(clientStore sdk.KVStore, height exported.Height) (uint64, bool)

GetProcessedTime gets the time (in nanoseconds) at which this chain received and processed a tendermint header. This is used to validate that a received packet has passed the delay period.

func IterateProcessedTime 

func IterateProcessedTime(store sdk.KVStore, cb func(key, val []byte) bool)

IterateProcessedTime iterates through the prefix store and applies the callback. If the cb returns true, then iterator will close and stop.

func ProcessedTimeKey 

func ProcessedTimeKey(height exported.Height) []byte

ProcessedTimeKey returns the key under which the processed time will be stored in the client store.

func RegisterInterfaces 

func RegisterInterfaces(registry codectypes.InterfaceRegistry)

RegisterInterfaces registers the tendermint concrete client-related implementations and interfaces.

func SetProcessedTime 

func SetProcessedTime(clientStore sdk.KVStore, height exported.Height, timeNs uint64)

SetProcessedTime stores the time at which a header was processed and the corresponding consensus state was created. This is useful when validating whether a packet has reached the specified delay period in the tendermint client's verification functions

func NewClientState

func (ClientState) CheckHeaderAndUpdateState 

func (cs ClientState) CheckHeaderAndUpdateState(
	ctx sdk.Context, cdc codec.BinaryMarshaler, 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).

func (ClientState) CheckMisbehaviourAndUpdateState 

func (cs ClientState) CheckMisbehaviourAndUpdateState(

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

func (ClientState) CheckProposedHeaderAndUpdateState 

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

CheckProposedHeaderAndUpdateState will try to update the client with the new header if and only if the proposal passes and one of the following two conditions is satisfied:

  1. AllowUpdateAfterExpiry=true and Expire(ctx.BlockTime) = true
  2. AllowUpdateAfterMisbehaviour and IsFrozen() = true

In case 2) before trying to update the client, the client will be unfrozen by resetting the FrozenHeight to the zero Height. If AllowUpdateAfterMisbehaviour is set to true, expired clients will also be updated even if AllowUpdateAfterExpiry is set to false. Note, that even if the update happens, it may not be successful. The header may fail validation checks and an error will be returned in that case.

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.
