Gaia v24 Upgrade

Background

This upgrade changes the LSM module to a refactored x/liquid module, which has been audited by Zellic. Docs for the module are available here. This work is needed to get the Hub unforked from the SDK, which would reduce our technical debt and ease future development. After the migration in this upgrade, we can complete the unforking in Gaia v25, targeted for mid / late June.

Gaia v24.0.0 is a major release that will follow the regular governance process for software upgrades on the Cosmos Hub.

Reminder – This proposal will have a voting period of just ONE WEEK.

If the proposal passes, validators will be required to update the Cosmos Hub binary at the halt-height specified in the on-chain proposal.

STATE BREAKING

This upgrade is state-breaking and mandatory once the on-chain vote passes and the upgrade-height is reached.

Testing and Testnets

The v24.0.0 release has gone through rigorous testing, including e2e tests, and integration tests by Interchain Labs. In addition, the upgrade process will be independently tested by the team at Hypha Co-op and will be performed by validators and node operators on a public testnet prior to cutting the final release.

If you wish to participate in the testnet upgrade process in the future, you can find the relevant information (genesis file, peers, etc.) to join the Cosmos Hub’s Interchain Security Testnet (provider) here.

Potential risk factors

As with any major upgrade, there always exists a risk that the Cosmos Hub might experience problems due to potential bugs or errors, even though extensive testing and simulation has been completed. In the case of serious problems, validators should stop operating the network immediately.

Coordination with validators will happen in the #cosmos-hub-validators-verified channel of the Cosmos Network 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 (v23.3.0).

Governance votes

The following items summarize the voting options and what it means for this proposal:

YES - You agree that the Cosmos Hub should upgrade to v24.0.0.

NO - You disagree that the Cosmos Hub should upgrade to v24.0.0.

NO WITH VETO - A ‘NoWithVeto’ vote indicates a proposal either (1) is deemed to be spam, i.e., irrelevant to Cosmos Hub, (2) disproportionately infringes on minority interests, or (3) violates or encourages violation of the rules of engagement as currently set out by Cosmos Hub governance. If the number of ‘NoWithVeto’ votes is greater than a third of total votes, the proposal is rejected and the deposits are burned.

ABSTAIN - You wish to contribute to the quorum but you formally decline to vote either for or against the proposal.
