Gaia v9.0.0 Release Notes

This is the final release for the Lambda upgrade which is proposed to take place at height 14,470,501. The date/time of the upgrade is subject to change as blocks are not generated at a constant interval. You can stay up-to-date using this live countdown page.

The chain id will remain cosmoshub-4.

For full upgrade instructions please see https://hub.cosmos.network/main/hub-tutorials/upgrade-node.html.

Be sure to monitor the #cosmos-hub-validators-verified channel in the Cosmos Hub Developers Discord as the estimated height approaches

Lambda Changelog :

• (feat) Add Interchain-Security v1.0.0 provider module. See the ICS Spec for more details.
• (gaia) Bump cosmos-sdk to v0.45.13-ics. See CHANGELOG.md for details.
• (gaia) Bump ibc-go to v4.2.0. See v4.2 Release Notes for details.
• (gaia) Bump tendermint to 0.34.26. See CHANGELOG.md for details.
• (gaia) Bump packet-forward-middleware to v4.0.4.
• (tests) Add E2E ccv tests. Tests covering new functionality introduced by the provider module to add and remove a consumer chain via governance proposal.
• (tests) Add integration ccv tests. Imports Interchain-Security's TestCCVTestSuite and implements Gaia as the provider chain.

---

Summary

This on-chain upgrade governance proposal is to adopt Gaia v9.0.0. By voting YES to this proposal, you approve of adding these updates to the Cosmos Hub.

This upgrade includes the Replicated Security feature.

The forum post discussing this upgrade can be found here.

Background

Since the last v8-Rho upgrade at height 14,099,412 there have been a number of updates, fixes and new modules added to Gaia.

Updates

• Bump cosmos-sdk to v0.45.13-ics. See CHANGELOG.md for details.
• Bump ibc-go to v4.2.0. See v4.2 Release Notes for details.
• Bump tendermint to 0.34.26. See CHANGELOG.md for details.
• Bump packet-forward-middleware to v4.0.4.

Features

• Add Interchain-Security v1.0.0 provider module. See the ICS Spec for more details.

Tests

• Add E2E ccv tests. Tests covering new functionality introduced by the provider module to add and remove a consumer chain via governance proposal.
• Add integration ccv tests. Imports Interchain-Security's TestCCVTestSuite and implements Gaia as the provider chain.

Testnet

V9 Lambda went live on the persistent testnet after the successful simulated upgrade. For more information, see the testnet upgrade proposal or block explorer, and visit the persistent testnet documentation.

On-Chain Upgrade Process

This upgrade can be performed in multiple ways. When the network reaches the halt height, the state machine program of the Cosmos Hub will be halted. The classic method for upgrading requires all validators and node operators to manually substitute the existing state machine binary with the new binary. Alternatively node operators can use the Cosmovisor utility to swap the binaries automatically. Cosmovisor also includes the ability to download the binaries automatically before swapping them. Documentation on Cosmovisor can be found here and instructions specific to the upgrade can be found here. If you are interested in trying Cosmosvisor with a simulated local upgrade please see the local testnet documentation. Because it is an onchain upgrade process, the blockchain will be continued with all the accumulated history with continuous block height.

Potential Risk Factors

Although very extensive testing and simulation has taken place there always still exists a risk that the Cosmos Hub might experience problems due to potential bugs or errors from the new features. In the case of serious problems, validators should stop operating the network immediately. Cosmos Core Contributors will coordinate with validators in the #validators-verified channel of the Cosmos Developer Discord to create and execute a contingency plan. Likely this will be an emergency release with fixes or the recommendation to consider the upgrade aborted and revert back to the previous release of gaia (v8.0.1).
