Cosmos Hub is currently voting on a critical software upgrade to address a governance query issue that arose after the v29 update. The problem, which made older proposals unreadable, has disrupted tools used to monitor network upgrades. Proposal 1061 aims to upgrade Gaia, the network's node software, to v29.1.0 at block 33,935,300 if approved. Voting closes Nov. 17 at 6:57 a.m. ET, with the upgrade expected around Nov. 18.
As of early Nov. 14, the onchain tally showed overwhelming support for the upgrade, with about 149.34 million $ATOM in voting power for the proposal, 167 $ATOM against, and 681 $ATOM abstaining. Turnout was approximately 43.35% of bonded $ATOM, exceeding the 40% quorum requirement with near-unanimous support.
The issue stems from v29's removal of x/params, a module that also removed the registration needed to interpret historical parameter-change proposals. While the old records remain onchain, nodes running the affected software cannot decode them. This failure affects proposal-list pages, status-filtered searches, and queries for individual proposals, disrupting services for validators and delegators.
If the proposal passes, validators must have the v29.1.0 binary ready for the scheduled block height. The upgrade guide advises operators to verify the release and stage it under the exact onchain plan name, v29.1.0, when using Cosmovisor. Validators that do not upgrade will be unable to continue past the upgrade height and will miss signing blocks.
