Barnard Release: Governance Unleashed

‍
Following Andromeda's finality boost, Barnard introduces critical self-governance, smart contract optimizations, and lays the final groundwork for Supernova and 600ms block times.

‍
Key changes:

• Protocol-level governance update (proposal creation, on-chain voting, automatic cleanup)
• Gas-penalty reduction (10× → 2×) for fairer execution
• New account state iterator endpoint
• Time granularity hooks (seconds → milliseconds)
• Go 1.23, VM hooks, node ops improvements

‍

This release marks a major evolution of the core SDK powering most dApps in the MultiversX ecosystem. Rewritten from the ground up, mx-sdk-dapp v.5.0.introduces a modular, framework-agnostic architecture designed for longevity, flexibility, and a significantly improved developer experience.

SpaceCraft SDK v0.59.0 is live.
‍
This release brings full support for the Barnard protocol upgrade, introducing expanded APIs, fallible transaction mechanisms, and improved contract tooling for MultiversX smart contract development.

It’s a major step forward for developers building advanced logic, tools, and governance flows on MultiversX.
