v0.4.2 Nolus Pirin Software Upgrade

Summary

This on-chain upgrade governance proposal is to adopt v0.4.2 for the Nolus Pirin mainnet which is currently running on v0.4.1. By voting YES to this proposal, you approve of adding these updates to the base layer protocol. This update seeks to introduce the following:

• Introduce the x/authz module. It allows an account (granter) to grant arbitrary privileges to another account (grantee) to execute transactions on their behalf.
  
• Add CosmWasm 1.2. It delivers important new features such as calculation of a smart contract address in advance.
  

Changes

A complete changelog can be seen in the v0.4.2 release on github.

On-Chain Upgrade Process

When the network reaches the halt height, the state machine program of Nolus will be halted. The classic method for upgrading requires all validators and node operators to manually substitute the existing state machine binary with the new binary. Validators can coordinate with each other on Discord in advance of the release. Please use the chat channel under the Validators section. The target block for the scheduled update is 3044000 which should happen on the 13th of December, 2023 (Wednesday) at around 09:15 UTC. As a disclaimer, this is a rough estimate assuming an average block time of 5.76 seconds.
