All coordination efforts will be done in the "SN Validators" Telegram group.
Make sure to backup your validator before making any changes.
Please read carefully before you begin the upgrade.
Note: The below instructions assume default installation. DO NOT COPY-PASTE if config.toml is not in ~/.secretd/config/config.toml or if you modified /etc/systemd/system/secret-node.service. If you have modified /etc/systemd/system/secret-node.service, you will need to re-apply those changes post installation and pre service restart.
When the network reaches the halt height 11,136,666, you'll see this message in your node's log (journalctl -fu secret-node):
Then, the upgrade steps for v1.12 are:
After restarting the node with v1.12, you should see INF applying upgrade "v1.12" at height: 11136666 in the logs (journalctl -fu secret-node). Once 67% of voting power comes online, you'll see blocks executing again.
Cosmovisor is a new process manager for cosmos blockchains. It can make low-downtime upgrades smoother, as validators don't have to manually upgrade binaries during the upgrade, and instead can pre-install new binaries, and Cosmovisor will automatically update them based on on-chain SoftwareUpgrade proposals.
⚠️ Cosmovisor is still new and best practices for using it are not yet established. If you don't feel adventurous at this time, we recommend upgrading the manual way.
For instructions on how to setup Cosmovisor, go here.
When the network reaches the halt height 11,136,666, the Secret Network blockchain will be halted and validators will need to take action to upgrade the chain to the secretd v1.12 binary (be it manually or automatically).
The proposal targets the upgrade proposal block to be 11,136,666, anticipated to be on Tuesday October 17, 2023 at 2:00 PM UTC.
The upgrade is anticipated to take approx 30 minutes, during which time, there will not be any on-chain activity on the network.
In the event of an issue at upgrade time, we should coordinate via the "SN Validators" Telegram group.
If as a result of a software bug the network fails to produce new blocks with the v1.12 binaries, the SCRT Labs team will distribute a v1.11 binary with a replacement v1.12 upgrade handler, which will allow the chain to revert to v1.11 while continuing to produce new blocks.
