Cosmos Hub 3 Upgrade Proposal D

Figment Networks (https://figment.network)

-=-=-

This proposal is intended to supersede flawed Cosmos Hub 3 Upgrade Proposal B (https://hubble.figment.network/cosmos/chains/cosmoshub-2/governance/proposals/14) and Cosmos Hub 3 Upgrade Proposal C (https://hubble.figment.network/cosmos/chains/cosmoshub-2/governance/proposals/15), regardless of their outcomes. This proposal will make both Proposal 14 and 15 void.

This proposal is intended to signal acceptance/rejection of the precise software release that will contain the changes to be included in the Cosmos Hub 3 upgrade. A high overview of these changes was successfully approved by the voters signalling via Cosmos Hub 3 Upgrade Proposal A: https://hubble.figment.network/cosmos/chains/cosmoshub-2/governance/proposals/13

We are proposing to use this code https://github.com/cosmos/gaia/releases/tag/v2.0.0 to upgrade the Cosmos Hub. We are proposing to export the ledger’s state at Block Height 1,933,000, which we expect to occur on September 24, 2019 at or around 1:53 pm UTC. Please note that there will likely be a variance from this target time, due to changes in block time (https://forum.cosmos.network/t/cosmos-hub-3-upgrade-proposal-d/2675/18?u=gavin). We are proposing to launch Cosmos Hub 3 at 60 minutes after Block Height 1,933,000.
