Summary

This on-chain upgrade governance proposal is to adopt v0.5.1 for the Nolus Pirin mainnet which is currently running on v0.5.0. By voting YES to this proposal, you approve of adding these updates to the base layer protocol. This upgrade introduces:

• The fee grant module which allows a given wallet address to grant fee allowances to other wallets. The grantees can then execute any transaction without having to maintain sufficient fees;
• Adjustment in the fee abstraction mechanism to allow paying fees with stablecoins;
• Nolus chain as an Interchain Accounts host network to allows other IBC protocols to utilize Nolus in an interoperable fashion;

Changes

A complete changelog can be seen in the v0.5.1 release on [Hidden link].

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 3958000 which should happen on the 12th of February, 2024 (Monday) at around 14:00 UTC. As a disclaimer, this is a rough estimate assuming an average block time of 5.75 seconds.
