Cosmos Hub Plans Gaia v29.1.0 Vote to Fix Broken Governance Queries

Cosmos Hub is preparing a governance vote on Gaia v29.1.0, a repair release that fixes governance queries broken by the chain's October 28 upgrade. The software upgrade proposal is planned around November 10, and the mainnet upgrade is planned around November 18.

What Broke

The v29 upgrade on October 28 removed the legacy params module as groundwork for Cosmos SDK 0.55. That change broke the decoding of 21 older parameter-change proposals. As a result, parts of the governance interface stopped working: the proposal list, status-filtered and single-proposal queries, tally queries and state export.

What Gaia v29.1.0 Fixes

The release restores decoding of historical ParameterChangeProposal content, which repairs all of the affected queries. It also bumps wasmd to 0.60.10 and wasmvm to 2.3.6. The release candidate v29.1.0-rc0 was published on November 2, and the provider testnet upgraded to it on November 3 at 14:00 UTC.

Because the release includes an upgrade handler, it goes through a coordinated software upgrade proposal. That proposal is planned on mainnet around November 10, with the mainnet upgrade itself planned around November 18. Validators are testing against the release first.

What Cosmos Hub Is

Cosmos (ATOM) is the native token of the Cosmos Hub, the central relay chain of the Cosmos ecosystem. ATOM is used for fees, staking and governance, and the Hub coordinates upgrades through on-chain votes. The Cosmos price chart on Coinranking tracks the market.

Cosmos was founded in 2014 by Jae Kwon and Ethan Buchman. The network uses Tendermint BFT consensus and the Inter-Blockchain Communication protocol to connect more than 100 independent blockchains. The Cosmos SDK is the developer toolkit behind the ecosystem's sovereign chains.

The Hub Unit team publishes a weekly update covering governance and releases. This week's update also flagged the Gaia timeline and asked validators to test the release before the vote.
