Documentation

Overview

Package client implements the ICS 02 - Client Semantics specification https://github.com/cosmos/ibc/tree/master/spec/core/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 GetTxCmd

func GetTxCmd() *cobra.Command

GetTxCmd returns the root tx command for 02-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 NewClientProposalHandler

func NewClientProposalHandler(k keeper.Keeper) govtypes.Handler

NewClientProposalHandler defines the 02-client proposal handler

func RegisterQueryService

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

RegisterQueryService registers the gRPC query service for IBC client.
