- Moderator edit to add link to on-chain proposal: [Mintscan - Chain explorer by COSMOSTATION](https://www.mintscan.io/cosmos/proposals/5) According to the expedited rules laid down in governance proposal #3 the following criteria needed to be met: 1. `v0.34.0` released by the development team 2. New testnet launched using that release. 3. No critical issues found during testing. `v0.34.0` has been released, and the upgrade procedure that will be followed for mainnet was carried out on the `gaia-13002` test on April 8th. The network came up with no issues and has been running w/o problems since then. Seeing as the conditions of the expedited process have been followed, we propose the following upgrade path: 1. Final code hash for Hub 0.34 state machine is `0f7877c23b407e24e56056469e90fe6b8a78d84c` 2. Gaia-13003 is a successful test of the upgrade procedure and final code 3. State export from `cosmoshub-1` is at block `507915` 4. Genesis time will be `2019-04-22T17:00:00Z UTC` 5. Validators can generate the new genesis file by running ```auto # must be run after the chain is stopped using v0.33.2 gaiad export —height=500000 —for-zero-height > cosmoshub-1-export.json # must be run after the upgrade to v0.34.0 python3 contrib/export/v0.33.x-to-v0.34.0.py —chain-id=cosmoshub-2 \ —start-time=2019-04-22T17:00:00Z \ cosmoshub-1-export.json > > genesis.json ``` ---

There is some debate between about block for export. @gamarin proposed exporting at block 507\_900 as this would be 10-12 hours closer to the target of 5pm GMT on April 22nd. I’m in favor of block 500\_000 for the following reasons. 1. in 10 years, no one will remember why we did 507\_900 but people will care about the integrity of the token distribution in the Cosmos Hub. A round number will stand the test of history better. 2. Validators running full nodes with the default options are storing the last 100 blocks of state and every 10,000th block. [https://github.com/cosmos/cosmos-sdk/blob/develop/store/types/pruning.go#L34](https://github.com/cosmos/cosmos-sdk/blob/develop/store/types/pruning.go#L34) Curious how other people feel? I don’t think planned downtime during this upgrade is a big deal. ---

Block 507\_900 was calculated using stargazer’s displayed block time of 6s ([https://stargazer.certus.one/](https://stargazer.certus.one/)). Apparently the real average block time is ~6.8sec, which changes the estimation entirely. With ~6.8sec block time, block 500\_000 happens ~1h before 5pm UTC, so it should work perfectly. This solves the issue, I think we can go with block 500\_000. ---

What are you guys using for an average block time? By my calculation we have just 20 minutes to export, upgrade, and restart: ``` Export at block 500,000 Current block 451,614 Blocks to go 48,386 Seconds per block 7 Seconds to go 338,702 Unix time now 1,555,612,481 Unix time export 1,555,951,183 Unix time genesis 1,555,952,400 ``` Seconds between export & genesis is 1,217, which is about 20 minutes. What am I doing wrong in this calculation or what am I not understanding about the export to genesis transition? 20 minutes doesn’t give much room for any kind of genesis file validation or upgrade error correction. ---

Thanks for clarifying! In this case, Figment Networks is also in favour of a block height of 500k 👍 ---

I think the genesis time is too tight. I agree 100% with Zaki that planned downtime is not a big deal, so we should have a buffer of a few hours between export and genesis. ---

By making your calculation at 7 seconds per block, aren’t you skewing your result to a later halt than actually planned? Block time is averaging 6.8s, so the halt should be ~9677 seconds earlier than you’re indicating. ~2 hours 40 minutes. ---

Is it not better to be conservative than aggressive in average block time? ---

I don’t feel strongly about it, but block time has been averaging between 6.75 and 6.80 seconds for the last 48 hours. So seems like ~3 hours from halt to genesis, if my math is correct. ---

500,000 is fine. My calculation is similar to Matt. It’s about `83 hours` from now (at height `456,735`, taking `6.85s` block time), which will be around `22 Apr 3pm UTC`. There will only be a 2-hour room for validators to export the genesis file and upgrade software. This is too short for all validators to do the job on Easter Monday. I think at least an 8-hour window is needed for all validators to wake up and clear our minds to make sure we are doing things right. ---

Is it correct that according to current conditions validators will have ~2,5h to upgrade the software? ---

It was a mistake for ```auto State export from cosmoshub-1 is at block 507915 ``` to make it into proposal 5. It was intended to be ```auto State export from cosmoshub-1 is at block 500000 ``` Immutability is hard but the whole point of the level of maturity of the system is we are writing human reabable text. ---

I think a genesis time of 19:00:00Z can make everyone happy. [Next page](https://forum.cosmos.network/t/proposal-5-accepted-transfer-enablement-proposal-expedited-cosmos-upgrade-proposal/1884.md?page=2)
