Documentation

Overview

Package client implements the ICS 02 - Client Semantics specification https://github.com/soomindae/ics/tree/master/spec/ics-002-client-semantics. This concrete implementations defines types and method to store and update light clients which tracks on other chain's state.

The main type is `Client`, which provides `commitment.Root` to verify state proofs and `ConsensusState` to verify header proofs.

Functions

func BeginBlocker

func BeginBlocker(ctx sdk.Context, k keeper.Keeper)

BeginBlocker updates an existing localhost client with the latest block height.

func ExportGenesis

func ExportGenesis(ctx sdk.Context, k keeper.Keeper) types.GenesisState

ExportGenesis returns the ibc client submodule's exported genesis. NOTE: CreateLocalhost should always be false on export since a created localhost will be included in the exported clients.

func GetQueryCmd

func GetQueryCmd() *cobra.Command

GetQueryCmd returns no root query command for the IBC client

func InitGenesis

func InitGenesis(ctx sdk.Context, k keeper.Keeper, gs types.GenesisState)

InitGenesis initializes the ibc client submodule's state from a provided genesis state.

func Name

func Name() string

Name returns the IBC client name

func NewClientUpdateProposalHandler

func NewClientUpdateProposalHandler(k keeper.Keeper) govtypes.Handler

NewClientUpdateProposalHandler defines the client update proposal handler

func RegisterQueryService

func RegisterQueryService(server grpc.Server, queryServer types.QueryServer)

RegisterQueryService registers the gRPC query service for IBC client.
