Prop 136: Pirin v0.6.2

Summary

This on-chain upgrade governance proposal is to adopt the Nolus Eden v0.6.2 update for the Nolus Pirin mainnet which is currently running on v0.5.3. By voting "YES" to this proposal, you approve of adding these updates to the base layer protocol. This upgrade introduces mainly Cosmos SDK v50 and CosmWasm 2.0. Below a detailed breakdown of the powerful new features and optimizations:

  • ABCI 2.0 with Vote Extensions: Unlocks the implementation of potential features like decentralized and permissionless block-by-block oracle prices.

  • IAVL v1: Brings significant improvements to disk storage and overall performance. These optimizations are key in reducing the block time of the Nolus chain boosting the transaction throughput.

  • Modular SDK: Core modules of the SDK are gradually extracted, reducing complexity.

  • IBC Callbacks: Allows smart contracts to seamlessly integrate with the ICS-20 (IBC token transfers) and ICS-27 (Interchain Accounts) standards.

  • Swagger API: Generation of a Swagger API documentation for a better overall developer experience.

Changes

A complete changelog can be seen in the v0.6.2 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 6556000 which should happen on the 05th of August, 2024 (Monday) at around 11:00 UTC. As a disclaimer, this is a rough estimate assuming an average block time of 5.75 seconds.
