Prop 995: Gaia v23.2.0 Upgrade

Proposal

On May 7th, Ethereum has a hard fork, the Pectra upgrade, which introduces changes that require the current Ethereum light client to be migrated to function with this hard fork.

This proposal upgrades the Cosmos Hub chain binary with a migrated Ethereum light client that will function with the new hard fork by providing the block height that the client will transition to the consensus mechanism used in the Pectra fork.

Motivation

IBC Eureka launched on the Hub before a block height was provided for the Pectra fork, hence the Ethereum light client could not be instantiated with the block height of the hard fork already specified.

Without a migration, when the hard fork takes place, the IBC connection between Ethereum and the Hub would be suspended, as the Ethereum light client will freeze.

Therefore this migration is necessary to avoid downtime, and maintain the connection’s liveness.

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

Governance votes

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

YES - You support upgrading the Ethereum light client to support the Pectra hard fork and keep the Ethereum <> Hub IBC connection live.

NO - You do not support upgrading the Ethereum light client to support the Pectra hard fork, and want the Ethereum light client to freeze, causing IBC downtime.

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.
