ClientState from Tendermint tracks the current validator set, latest height, and a possible frozen height.

• string chain_id = 1

• optional Fraction trust_level = 2

• optional google.protobuf.Duration trusting_period = 3

  duration of the period since the LastestTimestamp during which the submitted headers are valid for upgrade

• optional google.protobuf.Duration unbonding_period = 4

  duration of the staking unbonding period

• optional google.protobuf.Duration max_clock_drift = 5

  defines how much new (untrusted) header's Time can drift into the future.

• optional core.client.v1.Height frozen_height = 6

  Block height when the client was frozen due to a misbehaviour

• optional core.client.v1.Height latest_height = 7

  Latest height the client was updated to

• repeated ics23.ProofSpec proof_specs = 8

  Proof specifications used in verifying counterparty state

• repeated string upgrade_path = 9

  Path at which next upgraded client will be committed. Each element corresponds to the key for a single CommitmentProof in the chained proof. NOTE: ClientState must stored under `{upgradePath}/{upgradeHeight}/clientState` ConsensusState must be stored under `{upgradepath}/{upgradeHeight}/consensusState` For SDK chains using the default upgrade module, upgrade_path should be []string{"upgrade", "upgradedIBCState"}`

• bool allow_update_after_expiry = 10

  allow_update_after_expiry is deprecated

• bool allow_update_after_misbehaviour = 11

  allow_update_after_misbehaviour is deprecated

ConsensusState defines the consensus state from Tendermint.

• optional google.protobuf.Timestamp timestamp = 1

  timestamp that corresponds to the block height in which the ConsensusState was stored.

• optional core.commitment.v1.MerkleRoot root = 2

  commitment root (i.e app hash)

• bytes next_validators_hash = 3

Fraction defines the protobuf message type for tmmath.Fraction that only supports positive values.

Used in: ClientState

• uint64 numerator = 1

• uint64 denominator = 2

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.

Used in: Misbehaviour

• optional tendermint.types.SignedHeader signed_header = 1

• optional tendermint.types.ValidatorSet validator_set = 2

• optional core.client.v1.Height trusted_height = 3

• optional tendermint.types.ValidatorSet trusted_validators = 4

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

• string client_id = 1

• optional Header header_1 = 2

• optional Header header_2 = 3
