ClientConsensusStates defines all the stored consensus states for a given client.

• string client_id = 1

  client identifier

• repeated ConsensusStateWithHeight consensus_states = 2

  consensus states and their heights associated with the client

ClientUpdateProposal is a governance proposal. If it passes, the client is updated with the provided header. The update may fail if the header is not valid given certain conditions specified by the client implementation.

• string title = 1

  the title of the update proposal

• string description = 2

  the description of the proposal

• string client_id = 3

  the client identifier for the client to be updated if the proposal passes

• optional google.protobuf.Any header = 4

  the header used to update the client if the proposal passes

ConsensusStateWithHeight defines a consensus state with an additional height field.

Used in: ClientConsensusStates

• optional Height height = 1

  consensus state height

• optional google.protobuf.Any consensus_state = 2

  consensus state

Height is a monotonically increasing data type that can be compared against another Height for the purposes of updating and freezing clients Normally the VersionHeight is incremented at each height while keeping version number the same However some consensus algorithms may choose to reset the height in certain conditions e.g. hard forks, state-machine breaking changes In these cases, the version number is incremented so that height continues to be monitonically increasing even as the VersionHeight gets reset

Used in: ConsensusStateWithHeight, MsgUpgradeClient

• uint64 version_number = 1

  the version that the client is currently on

• uint64 version_height = 2

  the height within the given version

IdentifiedClientState defines a client state with an additional client identifier field.

• string client_id = 1

  client identifier

• optional google.protobuf.Any client_state = 2

  client state

MsgCreateClient defines a message to create an IBC client

• string client_id = 1

  client unique identifier

• optional google.protobuf.Any client_state = 2

  light client state

• optional google.protobuf.Any consensus_state = 3

  consensus state associated with the client that corresponds to a given height.

• string signer = 4

  signer address

MsgSubmitMisbehaviour defines an sdk.Msg type that submits Evidence for light client misbehaviour.

• string client_id = 1

  client unique identifier

• optional google.protobuf.Any misbehaviour = 2

  misbehaviour used for freezing the light client

• string signer = 3

  signer address

MsgUpdateClient defines an sdk.Msg to update a IBC client state using the given header.

• string client_id = 1

  client unique identifier

• optional google.protobuf.Any header = 2

  header to update the light client

• string signer = 3

  signer address

MsgUpgradeClient defines an sdk.Msg to upgrade an IBC client to a new client state

• string client_id = 1

  client unique identifier

• optional google.protobuf.Any client_state = 2

  upgraded client state

• optional Height upgrade_height = 3

  height at which old chain halts and upgrades (i.e last block executed)

• bytes proof_upgrade = 4

  proof that old chain committed to new client

• string signer = 5

  signer address
