# Details of upgrade time

This proposal suggests block #12801683 for the upgrade, which is estimated to be at Thursday 21th March 14:30 UTC, using avg block time of 5.9 secs https://www.mintscan.io/stargaze/blocks/12801683

When the network reaches the halt height, the state machine of the blockchain will be halted. Cosmovisor, if configured properly, will then switch the binary used for v13.0.0, and then the chain will continue to make progress.

In the event of an issue at upgrade time, we will coordinate via the #verified-validators channel in Discord.
