CHANGELOG

v6.2.0

October 4, 2024

DEPENDENCIES

FEATURES

  • [x/consumer] Populate the memo on the IBC transfer packets used to send ICS rewards. with the required consumer chain Id to identify the consumer to the provider.
  • [x/provider] Identify the source of ICS rewards from the IBC transfer packet memo. (#2290)
  • [x/provider] Enable permissionless allowlisting of reward denoms (at most 3) per consumer chain. (#2309)

STATE BREAKING

  • [x/consumer] Populate the memo on the IBC transfer packets used to send ICS rewards. with the required consumer chain Id to identify the consumer to the provider.
  • [x/provider] Identify the source of ICS rewards from the IBC transfer packet memo. (#2290)
  • [x/provider] Enable permissionless allowlisting of reward denoms (at most 3) per consumer chain. (#2309)

v6.1.0

September 20, 2024

BUG FIXES

  • Remove duplicate event emission on cached context. (#2282)
  • [x/provider] Add patch to enable ICS rewards from Stride to be distributed. (#2288)

STATE BREAKING

  • [x/provider] Add patch to enable ICS rewards from Stride to be distributed. (#2288)

v6.0.0

September 12, 2024

API BREAKING

  • [x/provider] Add the Inactive Provider Validators feature (as per ADR-017), which entails the following changes on the provider. (#2079)

    • Add max_provider_consensus_validators, a provider module param that sets the maximum number of validators that will be passed to the provider consensus engine.
    • Add no_valupdates_genutil and no_valupdates_staking, "wrapper" modules around the Cosmos SDK's native genutil and staking modules. Both modules provide the exact same functionality as the native modules, except for not returning validator set updates to the provider consensus engine.
    • Return the first max_provider_consensus_validators validators (sorted by largest amount of stake first) to the provider consensus engine.
    • Use the max_validators validators as basis for the validator sets sent to the consumers (max_validators is a staking module param).

  • [x/provider] The removal of VSCMaturedPackets entail several API breaking changes. (#2098)

    • Remove the oldest_unconfirmed_vsc query -- used to get the send timestamp of the oldest unconfirmed VSCPacket.
    • Deprecate the init_timeout_period and vsc_timeout_period parameters from the provider module.

  • [x/provider] Add the Permissionless ICS feature on the provider (as per ADR-019), which entails the following api-breaking changes on the provider. (#2171)

    • Deprecate the chain-id parameter in favour of consumer-id for all transactions and queries targeting a unique consumer chain. Below is a list highlighting the changes in the CLI commands. All commands assume the prefix interchain-security-pd tx|q provider.

      • Transactions:

      • Queries:

        • consumer-genesis [consumer-id] -- query for consumer chain genesis state by consumer id.

          • REST:/interchain_security/ccv/provider/consumer_genesis/{consumer_id}

        • validator-consumer-key [consumer-id] [provider-validator-address] -- query assigned validator consensus public key for a consumer chain.

          • REST: /interchain_security/ccv/provider/validator_consumer_addr/{consumer_id}/{provider_address}

        • validator-provider-key [consumer-id] [consumer-validator-address] -- query assigned validator consensus public key for the provider chain.

          • REST: /interchain_security/ccv/provider/validator_provider_addr/{consumer_id}/{consumer_address}

        • consumer-opted-in-validators [consumer-id] -- query opted-in validators for a given consumer chain.

          • REST: /interchain_security/ccv/provider/opted_in_validators/{consumer_id}

        • consumer-validators [consumer-id] -- query the last set consumer-validator set for a given consumer chain.

          • REST: /interchain_security/ccv/provider/consumer_validators/{consumer_id}

        • validator-consumer-commission-rate [consumer-id] -- query the consumer commission rate a validator charges on a consumer chain.

          • REST: /interchain_security/ccv/provider/consumer_commission_rate/{consumer_id}/{provider_address}

        • all-pairs-valconsensus-address [consumer-id] -- query all pairs of valconsensus address by consumer id.

          • REST: /interchain_security/ccv/provider/address_pairs/{consumer_id}

    • Deprecate the following queries, proposals and all legacy governance proposals:

DEPENDENCIES

FEATURES

  • [x/provider] Add min_stake, a power shaping configuration parameter that enables consumers to set the minimum amount of provider stake every validator needs to be eligible to opt-in. (#2035)

  • [x/provider] Add allow_inactive_vals, a power shaping configuration parameter that enables consumers to specify whether validators outside the active provider validator set are eligible to opt-in. (#2066)

  • [x/provider] Add the Inactive Provider Validators feature (as per ADR-017), which entails the following changes on the provider. (#2079)

    • Add max_provider_consensus_validators, a provider module param that sets the maximum number of validators that will be passed to the provider consensus engine.
    • Add no_valupdates_genutil and no_valupdates_staking, "wrapper" modules around the Cosmos SDK's native genutil and staking modules. Both modules provide the exact same functionality as the native modules, except for not returning validator set updates to the provider consensus engine.
    • Return the first max_provider_consensus_validators validators (sorted by largest amount of stake first) to the provider consensus engine.
    • Use the max_validators validators as basis for the validator sets sent to the consumers (max_validators is a staking module param).

  • [x/provider] Remove VSCMaturedPackets from the provider module, which entails the following changes to the provider. (#2098)

    • Remove unbonding operations pausing.
    • Remove the CCV channel initialization timeout.
    • Remove VSCPackets timeout.
    • Redesign key assignment pruning -- prune old consumer keys after the unbonding period elapses.

  • [x/provider] Add a query to get the blocks until the next epoch begins (#2106)

  • [x/provider] Add the Permissionless ICS feature (as per ADR-019), which entails the following CLI and API enhancements on the provider. (#2171)

    • Introduce new CLI commands and gRPC endpoints to manage consumer chains. All commands listed below assume the prefix interchain-security-pd tx|q provider.

      • Transactions:

        These new TX commands should be used instead of their corresponding deprecated proposals. To update consumer chains owned by the governance module, a proposal containing a MsgUpdateConsumer message must be submitted.

      • Queries:

        • consumer-chain [consumer-id]-- query details of a consumer chain associated with the consumer id.
          • REST: interchain-security/ccv/provider/consumer_chain/{consumer_id}
        • consumer-id-from-client-id [client-id] -- get the consumer id of a chain from a client id.
          • REST: interchain-security/ccv/provider/consumer_id/{client_id}
        • blocks-until-next-epoch -- query number of blocks remaining until the next epoch begins.
          • REST: interchain-security/ccv/provider/blocks_until_next_epoch

    • Improve the list-consumer-chains query to accept optional parameters [phase] and [limit]:

      • [phase]: Filters returned consumer chains by their phase.
      • [limit]: Limits the number of consumer chains returned.

  • [x/provider] Remove provider migrations to consensus versions lower than 7. To migrate the provider module from consensus version 3, 4, or 5 to consensus version 7 or higher, users should use v4.3.x in production to migrate to consensus version 6. (#2211)
