PROPOSAL DESCRIPTION

Figment Networks ( figment.network ) -=-=- Full proposal: ipfs.io -=-=- _Decision_ We are signalling that: 1. The Gaia 2.0.3 implementation is aligned with the list of high-level changes approved in Cosmos Hub 3 Upgrade Proposal A. 2. We are prepared to upgrade the Cosmos Hub to cosmoshub-3 based upon a. Commit hash: 2f6783e298f25ff4e12cb84549777053ab88749a; b. The state export from cosmoshub-2 at Block Height 2902000; c. Genesis time: 60 minutes after the timestamp at Block Height 2902000. 3. We are prepared to relaunch cosmoshub-2 a. In the event of: i. A non-trivial error in the migration procedure and/or ii. A need for ad-hoc genesis file changes iii. The failure of cosmoshub-3 to produce two (2) blocks by 180 minutes after the timestamp of Block Height 2902000; b. Using: i. The starting block height: 2902000 ii. Software version: Cosmos SDK v0.34.6+ github.com iii. The full data snapshot at export Block Height 2902000; c. And will consider the relaunch complete after cosmoshub-2 has reached consensus on Block 2902001. 4. The upgrade will be considered complete after cosmoshub-3 has reached consensus on Block Height 2 within 120 minutes of genesis time. 5. This proposal is void if the voting period has not concluded by Block Height 2852202. -=-=- _Context_ This proposal follows Cosmos Hub 3 Upgrade Proposal D ( hubble.figment.network ) aka Prop 16, which passed in vote, but failed in execution ( forum.cosmos.network ). This proposal is intended to succeed where Prop 16 failed. 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 level overview of these changes was successfully approved by the voters signalling via Cosmos Hub 3 Upgrade Proposal A: hubble.figment.network We are proposing to use this code github.com to upgrade the Cosmos Hub. We are proposing to export the ledger’s state at Block Height 2,902,000, which we expect to occur on December 11, 2019 at or around 14:27 UTC assuming an average of 6.94 seconds per block. Please note that there will likely be a variance from this target time, due to deviations in block time. We are proposing that the Cosmos Hub 3 genesis time be set to 60 minutes after Block Height 2,902,000. -=-=- Co-ordination in case of failure will happen in this channel: riot.im
